He also can transform into another Legend Rider Form and some other fictional character if he has a card from a fictional character that is concerned.

Tsukasa is an interesting individual to say the least. Initially, one would get the impression that he’s an irritating, hypocritical, cavalier, and a bit self-righteous, and well, that’d be correct, to a point. He tends to press forward regardless of the situation, most cases seeming to have a certain "I'm better than you" attitude about it all. He seems cold when it comes to others, and like someone that would be terribly ignorant about things (despite the fact that he’s very talented when it comes to everything). Of course, this is pretty much just the impression anyone gets from watching him for a little while. He’s uncaring, rude, and mostly kind of a bad person.

All in all, he’s not a terrible person. He’s just bad with other people. He wants to find a home and somewhere he belongs and that’s really all his grand aspirations end up being. He also really likes photography but, the photos that he takes always having bad results.

Usually, before he transform into Decade and fight his opponent, Tsukasa would say "Tōrisugari no Kamen Raidā da, oboeteoke!" (I'm just a passing-through Kamen Rider. Remember that!)

A masked man orchestrates a "King Game", saying that whoever wins the game will become king of the world. Anyone who fails a task in the game will be killed by Another Ryuki. When Yusuke Onodera, Misa Kudo, and Swartz observe a deceased old man who has been killed by a mysterious person while holding a lot of cash, Tsukasa appears and greets Yusuke after not seeing each other for a long time. At first, the remaining people in the mansion are suspicious because of Tsukasa and Yusuke's acquaintance. Tsukasa explains to his old friend that the mansion they are in is the entrance to a dimensional gap and that the "King Game" has happened many times in the past. He also reveals that the true mastermind of the King Game is the "True Sougo", a man destined to become Ohma Zi-O, who has also become weakened because of having used "too much power". He further notes that nobody is to be trusted in the mansion, since it is connected to various worlds, and no one can know who is from what dimension. The next day, the masked man appears on TV and continues the game, with Tsukasa as a participant. This time, the challenge is some simple games of rock-paper-scissors. However, if 5 games end in a draw, everyone will die. Misa Kudo decides to be the loser voluntarily, saying that she has a plan. Another Ryuki promptly appears and kills her for being the loser. Swartz mocks Misa for being too weak, only to be shoved food in the mouth by Tsukasa. While eating, he proclaims he cannot lose, to draw the "true Sougo" out. The Game continues. This time, it is a hide-and-seek challenge where anyone first found by Another Ryuki will lose. Swartz is killed by an unknown person while playing, alerting Tsukasa. Before dying, Swartz tells him he wants a poisoned dumpling. The masked man reveals his final challenge: The rest of the mansion must each find a treasure weapon in the compound and use them to kill one another until there is only one left, and Another Ryuki will be killing them at random also. Tsukasa manages to find a sword. He walks outside and finds Yusuke, but the latter does not want to open his box of treasure and gives Tsukasa instead. Distracted, Tsukasa is sneak-attacked by Yusuke, who reveals himself to be the mysterious killer all along. He notes that Yusuke is not the same Yusuke Onodera he knows and quickly deducts that he is from an alternate dimension. Soon after, just as Yusuke thinks he has won, Sougo shows up, having survived the attempt on his life thanks to his robot physiology. At this point, Tsukasa learns that nearly every player in the King Game is not the same person that as he knows: Sougo Tokiwa is a robot from a timeline where humanity has been destroyed and replaced by machines, Heure is a space ninja, and Misa is a ghost. The robot Sougo then helps Tsukasa back to the mansion. Inside, the masked man finally makes his presence and identity known: He is none other than Decade's old enemy, Narutaki. He explains that the "true Sougo" has become very weak somehow, and he creates this Game to find a suitable body, with Narutaki acting as the referee. Just then, Ohma Zi-O appears inside a mirror, attempting to take Yusuke as the body, but Yusuke proves to be unsuitable as a host and disintegrates. At this point, Narutaki confesses that he has become tired of his role as the referee, and has guided Tsukasa to the mansion so that the Game could be stopped. Tsukasa and Sougo transform and jump into the mirror to battle Ohma Zi-O. In the wasteland, the two are joined by Kamen Riders Diend, Kiva-la, and Kuuga. Despite outnumbering the tyrant, they quickly find themselves on the losing side. Zi-O, seeing no other choice, gives Decade the Saber Ridewatch, telling him to deliver it to someone who can use its power. Decade and the four other Riders are then defeated by Ohma Zi-O in a massive explosion.

And for Rider Time: Kamen Rider Zi-O VS Decade - 7 of Zi-O!, After having survived the battle with Ohma Zi-O, Decade is still hellbent on ending his reign. Due to a distortion within several different timelines focused around their versions of Sougo Tokiwa, Tsukasa returns to destroy the resulting world by killing all of the alternate Sougos within, while trying to prevent Ohma Zi-O from rising to power as well. Driving a jeep towards Hikarigamori Academy, he spots a frightened, cowardly Sougo trying to run from him, Tsukasa stops the jeep to transform into Decade, and instantly kills this Sougo with a Final Attack Ride. Tsukasa eventually arrives at Hikarigamori, but turns around when the actions of Sougo C lead to a fight and lure out several more alternate Sougos. The night afterward, it is revealed that Tsukasa is slowly starting to disappear, showing that his wound during the stab from the evil Yusuke and Ohma Zi-O actually endangering his life because Tsukasa has yet to be treated into full condition. After the other alternate Sougos are erased through a mix of infighting and Tsukasa's own actions, the mysterious child Tsukuyomi has been helping appears and reveals himself as yet another alternate version of Sougo (The "True Sougo" that Tsukasa has been hunting) who has now become Ohma Zi-O. Tsukasa attempts to intervene by equipping the K-Touch 21 and transforming into Decade Complete Form 21, but his weakened condition proves fatal, with Ohma Zi-O easily defeating Tsukasa once more. Once Sougo A manages to remanifest, he finds Tsukasa near the pond where Ohma Zi-O has defeated him earlier, and is given the Saber Ridewatch. Following Ohma Zi-O's destruction at the hands of Zi-O DecadeArmor Saber Form, Tsukasa begins to disintegrate, relieved that his journey will finally be over before quietly passing away and restoring all seven timelines to their original state. Although he is seemingly dead, Black Woz does believe Tsukasa and Ohma Zi-O may return in the near future.

Decade VS Ohma Zi-O: Final Stage (Violent Emotion Decade's Rebirth)
Finally, after some time, Tsukasa has revived again and began to do his activity and his journey as the overseer of the Kamen Rider Multiverse as usual. Until in the end, there is an event, which is the same as the incident in Movie War 2010, that Parallel Worlds is merged again. The Alternative Riders are starting to hunt for Decade again, because Decade is revived again, and Decade here also regains his Violent Emotion Form again, which is called Neo Violent Emotion Decade, where the power is the same as the basic Violent Emotion Decade, but here he can access additional powers from Heisei Phase 2, the same as Neo Decade, because it is the Neo Form of Violent Emotion Decade. Decade finally had to return to face the alternative Riders from Showa and Heisei Phase 1 and Heisei Phase 2, and again became the Destroyer of Riders. It is not known who ordered these alternative Riders to kill Tsukasa, which is certain after Tsukasa defeated all the existing Riders, it is known that the one who ordered it was Ohma Zi-O himself to destroy the existence of the Decade. Indeed, even though it was repeatedly destroyed, Ohma Zi -O will always be there if Sougo still has dreams of becoming King, no matter which version of Sougo is. And finally, there was a duel between Tsukasa who became Neo Violent Emotion Decade and Ohma Zi-O. At first, as usual, Tsukasa was still having trouble fighting Ohma Zi-O at that time, even Tsukasa didn't even get the chance to attack Ohma Zi-O until finally, his old K-Touch and his K-Touch 21, fused and upgraded to K-Touch Ultimate. Finally, Tsukasa used K-Touch Ultimate to transform into Decade Ultimate Complete Form. Even though Tsukasa still has a hard time-fighting Ohma Zi-O with this form, Tsukasa with this form has also experienced an increase in his strength and abilities which makes him also slightly able to keep up with Ohma Zi-O. And in the mid of their duel, Diend also appeared with his new Final Form, which is also Ultimate Complete Form or Diend Ultimate Complete Form. Finally, the two of them together tried to defeat Ohma Zi-O, and finally, they were able to defeat Ohma Zi-O in the Rider Kick collide, where Ohma Zi-O used his Ohma Zi-O Hissatsu Geki and Decade and Diend used their Final Attack Ride, Decade & Diend Ultimate Dimension Kick. After defeating Ohma Zi-O, Decade returned to his Neo Violent Emotion base form and Diend also returned to his base form. Then suddenly, Decade is interfered by Kuuga Ultimate and Grand Zi-O, where this Kuuga Ultimate turns out to be Yusuke Godai, who is the Original Version of Kamen Rider Kuuga. They finally attacked Decade and beat him mercilessly, and at that time Decade was also very overwhelmed in facing them, especially when facing Kuuga Ultimate, because the fighting style of Yusuke Godai was so brutal it even broke Decade's belt. Initially, Kaito was just silence seeing Tsukasa being beaten up by Kuuga Ultimate and Grand Zi-O because he felt that it was not his business, but seeing Tsukasa who was dying, finally, Kaito decided to help Decade and gave the real reason why Decade destroyed the Alternative Riders from Showa and Heisei, it was because they had been controlled by Ohma Zi-O and Ohma Zi-O also already defeated at that time, finally, they stopped their persecution to Decade, and Decade when they were very dying even said to have experienced internal organ failure as a result from their attacks let alone Kuuga Ultimate's attack until finally, Sougo (Grand Zi-O) decided to take the remnants of the aura of power from Ohma Zi-O to restore the alternative world and after the alternative world was restored, all the dead Riders came back to life, and also Tsukasa started to recover and recover once and at the same time as his Neo Violent Emotion form changed into a basic Neo Decade form.

Lost in Genshin Universe
After the events in Decade VS Ohma Zi-O: Final Stage, Tsukasa finally started to return to his duties as an overseer of the Kamen Rider Multiverse and also observed the development of the Universe and the Timeline of the Kamen Rider Multiverse, until finally, he found an oddity, which is the emergence of a portal near the Hikari Photo Studio, but it seems that the portal has no connection with the world of Kamen Rider, the portal seems to lead to another world which is not from the Kamen Rider world, and initially, Tsukasa thought that this portal is connected to the Super Sentai world. Finally, Tsukasa entered the portal and was very surprised to him because it was not the World of Super Sentai but another world that he did not know at all, which turned out to be the Genshin Impact World or Genshin World. Suddenly the portal closes and Tsukasa can't return to the Rider world again, finally, he tries to use his Aurora Curtain to get away from that world but it turns out that he was instead get teleported to Snezhnaya. After he arrived at Snezhnaya, he was immediately intercepted by Snezhnaya's troops and also several troops from the Teyvat Defense Forces Division, finally, Tsukasa was forced to fight and defeat them all. After Tsukasa defeated them all, finally the news about an outsider who slaughtered the Snezhnayan and Teyvat Defense Forces Division troops spread throughout Snezhnaya and even outside Snezhnaya which finally made Childe order all his troops to hunt Tsukasa, and this is where the story of Decade in Genshin World begins.

The Outsider Invasion: The Attack of Kamen Rider Decade, The Passing Through Kamen Rider arc
Tsukasa has now is become a fugitive of the whole Snezhnaya and a fugitive of the Teyvat Defense Forces Division, he was at that time also nicknamed as "Pink Armored Barcode Outsider". At that time Tsukasa tried to find a hiding place in Snezhnaya to avoid the pursuit of the Snezhnayan troops and the Teyvat Defense Forces Division. 4 days passed, by that time Tsukasa was already getting tired because there was no food and the temperature was very cold at that time. Finally, Tsukasa decides to go to the nearest town in Snezhnaya to find food and find shelter, hoping that people there will not recognize him and suspect him. While on the way, he accidentally met Childe, who was with Kayla at the time, and now they also were in the middle of an icy field surrounded by forests and mountains with a very cold temperature at that time. Childe, who realized that he was the fugitive he had been looking for all this time, immediately tried to attack Tsukasa with his Revolver. Tsukasa was finally shot twice in the chest, and luckily he immediately turned into Kamen Rider Decade and there was a fierce battle between the two of them. The fight between the two looks balanced until finally Childe immediately transforms into his Foul Legacy Transformation to urge Decade and after Childe manages to urge Decade, he immediately accesses his strongest form by using his Archon Form to finish off Decade. Fortunately at that time Decade managed to outwit Childe by using his Attack Ride: Illusion to make 3 clones to outwit Childe and he immediately changed to his Final Form, Decade Ultimate Complete Form. Finally, there was a very fierce battle between them, the strength of the Decade Ultimate Complete Form could even match the strength of Childe with his Archon Form, even though Decade at that time was still having a hard time facing Childe, even Kayla who witnessed their battle said that their battle until it destroys 3 Mountains. In short, Childe managed to push and corner Decade once again by hitting him so that he bounced up into the sky, and at that moment in the sky, at that moment Childe wanted to immediately end Decade, but Decade cunningly, again used Attack Ride: Illusion to create a clone which then the clone immediately headed for towards Kayla and held her hostage. Childe has finally fooled again because of that, he was confused about whether he should finish Decade or save Kayla, finally, Decade used this opportunity to finish off Childe with a Final Attack Ride, Childe who didn't have time to counter had to lose after being hit by the Ultimate Dimension Kick belonging to Decade. Finally Decade returned to his Basic Form and the dead Childe finally turned into a card and the card was taken by Decade, and this card is the first Rider Card which is the Rider Card of the Genshin Impact character which Decade also managed to get. Kayla who saw it was very shocked and cried very bitterly, she even called Decade as Terrible Devil. He also finally tries to fight Decade by taking Childe's Revolver and shooting it at Decade, but Tsukasa in his Rider Form is not affected by any shots, until finally Kayla recklessly runs and attacks Decade. Decade easily countered Kayla's attack and immediately knockouted Kayla by just kicking her, and after that, Decade immediately left Kayla who fainted, alone in that place.

Tsukasa, who at that time had recovered because he could regenerate while in Decade Form, finally decided to immediately leave from Snezhnaya, and at that time the World Guardian Corps had also started to help deal with this case. Tsukasa finally went to Mondstadt, to the Starsnatch Cliff. When Tsukasa was relaxing in the Starsnatch Cliff area, suddenly he was visited by 200 World Guardian Corps troops and also Razor. And it is also known that previously he had also spread terror throughout Teyvat several times which caused the World Guardian Corps to intervene to overcome this problem, and for that, the Great Commander of the World Guardian Corps, Aether Minci, ordered his troops to immediately hunt down Tsukasa. Finally, Tsukasa turned into Decade and there was a fight between Razor and his troops against Tsukasa, in short Tsukasa was overwhelmed to fight them, he never even got a chance to strike back or change to his Final Form and also his Rider Armor has started to be badly damaged. Finally, Tsukasa decided to immediately leave from there using his Aurora Curtain. Knowing that he had started to be hunted by a world, he finally decided to destroy that world, by killing the main character from that world, he tried to find information about Genshin World and Teyvat from several people there and he also knew the fact that there were already many people from the world. outside of Genshin World who can go to Genshin World other than himself. After he got enough information about Teyvat and Genshin World, he started looking for information about who the main character from this world was, he accidentally met an Outsider who turned out to be Sasuke Uchiha, he had been in Genshin World for a long time and he also decided to try seeking legality to become a citizen of Genshin World. Sasuke tells Tsukasa that the main character of this world is a 14 years old kid named Aether Minci. He was the son of the then ruler of Mondstadt and he was also the Great Commander of the World Guardian Corps. After getting some information about Aether from Sasuke, Tsukasa decides to look for more information about Aether, he goes around Teyvat to find more information about Aether, after getting enough information about it, Tsukasa gets ready to carry out his plan of defeating Aether and destroying Genshin World.

In short, Tsukasa already knows where Aether is currently, he knows if Aether is currently in Liyue's area, finally he is waiting at the place where Aether will pass, Aether at that time also still didn't realize who Tsukasa was, and in fact, the person that he met at that time was the person he had been looking for all this time. In short, Aether finally passed that place and without thinking, Tsukasa immediately intercepted him and invited him to fight, he also said that after defeating him, he would immediately destroy this world. Finally, Tsukasa transforms into Kamen Rider Decade and he immediately attacks Aether. Aether calmly tries to resist and dodge Decade's attacks while enjoying his favorite Lollipop. When fighting Aether, Decade up to 4x transformed into another Rider Form such as Kamen Rider Hibiki to attack Aether with Kibōjutsu: Rekkadan, but Aether managed to counter it with Cosmo Pyro Bullet Shot, then he transformed into Kamen Rider Fourze Elekstates Form to attack Aether with Electrical Slash, but again Aether was able to counter it with her Cosmo Electro Cross-Slash, she also transformed into Kamen Rider Double FangTrigger to attack Aether with FangTrigger Bow Shoot, and Aether was able to counter it again with Cosmo Anemo Pyro Great Slash, until finally, Decade decided to change to Kamen Rider Kuuga Ultimate Form and tried to finish Aether with Kuuga Ultimate Kick, but Aether managed to counter it with Aether Hyper Kick which then made Decade in Kuuga Ultimate Form bounced far away. Aether, who was already getting annoyed by Decade, immediately summoned Kamen Rider Blade King Form to fight Decade. Decade also looks very overwhelmed when fighting Kamen Rider Blade King Form which requires him to access his Final Form, finally, Decade turns into Decade Ultimate Complete Form, and finally, with great difficulty, Decade manages to defeat Kamen Rider Blade King Form which was summoned by Aether. Finally, Aether summoned 3 Kamen Rider Ohma Zi-O at once whose strength was 2x stronger than the original version, at this point Decade again had to desperately face 3 Ohma Zi-O at once, even by making 2 clones to help himself. still not enough to defeat the 3 clones of Ohma Zi-O until he finally decided to use the power of Kamen Rider J and transformed into Kamen Rider Decade Jumbo Ultimate Complete Form to fight against the 3 Ohma Zi-O, and Decade can destroy that 3 Ohma Zi-O with only 10 attacks with using Ride Booker Slash Mode and Attack Ride: Slash. Finally, Decade returned to its normal size and he also ran out of patience and immediately wanted to finish off Aether with his Rider Kick and when he launched his Rider Kick attack called Ultimate Dimension Kick, suddenly Aether easily countered him with his Aether Super Punch. Finally Decade lost and he also gave up on Aether, which finally made Aether immediately send him back to his homeworld, Kamen Rider World. But suddenly he realized something if that person was the Pink Armored Barcode Outsider that people had been looking for all this time and finally he immediately pulled Decade back to Genshin World. And when Aether was about to catch and execute it, suddenly that person also showed a card with Childe's picture. He explained that he got the card after he defeated and killed Childe in Snezhnaya and he also knew that the person on the card had a relationship with Aether. He asked to be forgiven and also he said he will bring that person back to life. Previously he had also told the chronology of how he met Childe and also how he defeated that person and he also told his real name, Tsukasa Kadoya. Finally, they immediately went to Snezhnaya and the place where Tsukasa / Decade defeated Childe, and finally, Tsukasa tried to revive Childe by trying to get Childe out of the card, but that failed and Tsukasa could only surrender because he couldn't return it all over again. Aether, who knew the sincerity of Tsukasa who already regretted his actions, finally forgive him and allowed him to go.

After Tsukasa leaves the place, he accidentally meets a mysterious man who calls himself "The Reader". He explained himself to Tsukasa, he explained that he was a reader of this story, and he also said that he came from a world called the "Real World", he also explained that he and the other "Readers" could do anything in this world or what they call as the "Fiction World" or you could say if they are all is an omnipotent figures. Not long after their conversation, The Reader gave Tsukasa a Rider Card which was revealed to be the Ohma Zi-O Rider Card. Not long afterward, 6 days later, Tsukasa came back to Aether and challenged him to a duel again. He did this because he believed, that he could defeat Aether with his Ohma Zi-O Rider Card. Eventually, Tsukasa turned into Ohma Zi-O and began to challenge Aether who was enjoying his Lollipop. Finally, without further ado, Tsukasa with his Ohma Zi-O Form decided to immediately finish off Aether with Ohma Zi-O's Rider Kick, namely Ohma Zi-O Hissatsu Geki, but it turned out that Aether easily managed to counter him with his Aetherkinesis, finally Tsukasa returned to his human form and he also said that if it was just a test to find out how much strength Ohma Zi-O he had, he also gave Aether lots of candy to convince him because he knew that Aether really liked candy, and finally Aether accepted it and started to believe Tsukasa's words. And finally, he also knew that the reason Tsukasa did that was to protect himself because when he first came to this world and arrived at Snezhnaya, he was already considered a threat and he also got threatened by the presence of Snezhnaya troops and the Teyvat Defense Forces Division troops who have acted aggressively against him even though actually he already give up and asked them not to act aggressively to him, and that's what forced him to fight them all. After that, Tsukasa finally decided to go from there, to the Main City of Liyue.

The Kamen Rider Decade: Chapter 1 (Another Decade) arc
While on his way to the main city in Liyue, he was suddenly confronted by a mysterious Kamen Rider, his form is like a monster and in Kamen Rider World, this creature is called Another Rider, and Another Rider who appears at this time is Another Decade. Another Decade at that time was also hunting for Tsukasa to take all his strength, Tsukasa was surprised that he immediately transforms into Decade and fought Another Decade. Tsukasa, who is confused as to why Another Decade wants his power, tries to remind him that he and Another Decade previously had no problems or had been at peace since the events after Rider Time: Kamen Rider Zi-O VS Decade - 7 of Zi-O!. At that time, Tsukasa initially thought that the person behind Another Decade was Swartz, but finally, he realized that Another Decade was not Swartz because Another Decade's behavior was very different from Swartz, and this Another Decade didn't seem to understand the relationship at all. that existed with them in previous events. Because the power of this version of Another Decade is very strong, even stronger than Swartz's version of Another Decade, and Tsukasa is also getting overwhelmed, Tsukasa finally decides to run away with his Aurora Curtain.

After he managed to escape from Another Decade, he immediately rushed to the main city of Liyue and when Tsukasa was near the harbor area, he accidentally saw Kayla who was with Xiao at that time and it turned out that Kayla was also aware of it. Kayla, who is still shrouded in revenge because of Childe's death, immediately attacks Tsukasa with Childe's relic Revolver, luckily Tsukasa managed to dodge Kayla's shot and he immediately left the place, Kayla tried to chase him, but in the end, she lost track of Tsukasa. Tsukasa who managed to escape from Kayla, finally continued his journey, and finally, he arrived at the center of Liyue city, it turned out that he deliberately went to Liyue to find a place to live in this Genshin World, he thought that Liyue was the most suitable Nation for him to live in this world. At that time he wanted to find Ningguang, who was a Tianquan or Liyue ruler at that time, he tried to find information about Ningguang, and finally, he got all the information he needed to meet Ningguang and to meet Ningguang, finally, he was directed by a soldier in there, to go to the Jade Chamber if he wants to meet Ningguang. Finally, Tsukasa went to the Jade Chamber accompanied by several subordinates from Ningguang. Finally, Tsukasa arrived at the Jade Chamber and met Ningguang. When asked what purpose he came to this world and Liyue by Ningguang, Tsukasa replied that he wanted to live in this world and he also wanted to live in Liyue. Ningguang who heard Tsukasa's answer was very surprised, he considered that it was very difficult for Outsiders to get official legal residence rights and become residents of the Genshinverse, while Tsukasa easily asked him to live in Liyue, even though he was not the one who had the right to decide Tsukasa's status in the world. Ningguang also said that it would be best before he requested to live here, he would have to deal with the Teyvat Union or the World Guardian Corps to apply for the right to become an official resident of the Genshinverse and there was no need to meet her in person if he wanted to apply for the right to live in Liyue because someone was already there taking care of it other than herself, but Tsukasa easily said that he was a good friend of her nephew, Aether Minci, it turned out that Tsukasa also knew about the relationship of this Aether. Ningguang was surprised after knowing this, she thought that it was rare for Aether to have a good friend who was an outsider, Ningguang who just believed Tsukasa without knowing that Tsukasa was still in an illegal status in that world, immediately gave him special residence rights in Liyue, because of his relationship with her nephew.

3 days later, Tsukasa is enjoying his life in Liyue, because he gets special treatment from Ningguang because of his confession that he is a good friend of Aether. While Tsukasa was enjoying his leisure time, he suddenly heard the news that Liyue was being attacked by an outsider, all of Liyue's special forces were deployed to defeat the outsider, but no one was able to fight the outsider, even the outsider had massacred all the Teyvat Defense Forces Division troops, which was in the Liyue harbor area at that time had about 400 people. Tsukasa who saw this was surprising because it turned out that the outsider in question was Another Decade, knowing Tsukasa was there, Another Decade shouted that his purpose here was to find Tsukasa and kill him and take his power, finally to avoid more casualties, Tsukasa agreed to fight With Another Decade, Tsukasa finally transforms into Decade and fights him. Another Decade's strength at that time was far superior to Decade, this made Decade very overwhelmed and even became a punching bag for Another Decade. Decade who is already overwhelmed also intends to finish him off with the power of Ohma Zi-O, when Decade wants to change to Ohma Zi-O's form, Another Decade immediately punches his Neo Decadriver Belt which causes his Neo Decadriver Belt to be badly damaged and he returns to his human form, and at that moment Another Decade finished off the helpless Tsukasa with his Dimension Punch. Tsukasa who was dying finally died which turned out his body suddenly disappeared from there, along with the arrival of Aether, Venti, Xiao, and Razor and their World Guardian Corps troops, Aether immediately asked Another Decade to surrender and he would be sent back to his original world, but Another Decade refuses because he hasn't gotten the power from Tsukasa, he still wants to find Tsukasa's whereabouts to take all his power. Razor continued to forcefully warn Another Decade to immediately surrender and cooperate with the instructions of his commander, Aether, but this was ignored by him and he instead took Kayla hostage who was also nearby, Xiao who tried to save Kayla was easily rendered helpless. by Another Decade with just one attack, because of this Aether immediately attacked Another Decade with his Aetherkinesis and attacked him with Aether Hyper Slash which managed to make Another Decade seriously injured, but in the end, Another Decade managed to escape with his Aurora Curtain.

Tsukasa finally came back to life and regained consciousness, but when he tried to wake up again, he felt something strange, like a lot of death aura around him and when he looked around, he realized that he was now in a world of the dead called the Underworld. Suddenly he gets a mysterious whisper that says if he wants to get out of the Underworld, he must be able to defeat the ruler of the Underworld, namely The Leviathan. At that time Tsukasa tried to use his power, namely to create a Dimension Wall/Aurora Curtain so he could teleport but it turned out that his power was completely useless in the Underworld, Tsukasa began to lose hope at that time, and at the same time 2 Underworld creatures suddenly attacked him, and because Tsukasa immediately ran away from that place, and while on the run, he continued to be chased by more Underworld creatures and finally he came to a place like a big tree with a big mirror. He also hid there until the Underworld creatures stopped chasing him, feeling safe, Tsukasa finally came out of his hiding place and contemplated near the tree. When Tsukasa was contemplating, he suddenly remembered the figure of Tenkuji Takeru the last time they met, Tsukasa saw that Takeru could control the dead realm. He also felt that the existence of Takeru's natural control power of the dead could reach Genshin World. Finally, with hope, Tsukasa tries to absorb the energy of the power while asking Takeru to touch the feeling and give him the power of the dead realm. Finally, Tsukasa managed to get all the energy from Takeru and resonate it with the death energy in the Underworld, and finally, with that power, he was able to transform into Kamen Rider Ghost Demon Damashii Rider. He immediately rushed to the place where the King of the Underworld was. Tsukasa with the power of Kamen Rider Ghost Demon Damashii Rider can easily defeat the Underworld creatures that confront him until finally, he arrives at the place where The Leviathan, King of Underworld is located. Finally, he invited Leviathan to fight and in short with great difficulty, Tsukasa managed to defeat Leviathan with the Hell Demon Omega Drive Kick from Kamen Rider Ghost Demon Damashii Rider and immediately turned it into a card. It is known that the power of Leviathan can destroy the world. Finally, Tsukasa managed to get out of the Underworld and return to the normal world.

After returning from Underworld, Tsukasa accidentally reunited with Another Decade, and Another Decade, knowing that Tsukasa was still alive, immediately attacked Tsukasa, but Tsukasa was not injured after being hit by Another Decade's attack, due to the power of Kamen Rider Ghost Demon Damashii Rider. Finally, Tsukasa transforms into Kamen Rider Ghost Demon Damashii Rider again and returns to fight Another Decade, with the power of Ghost Demon Damashii Rider, Tsukasa can easily outperform Another Decade even to the point of draining half of Another Decade's power, and because of this, Another Decade finally decided to retreat to recover his strength back. After that fight, suddenly the power of Kamen Rider Ghost Demon Damashii Rider disappeared and was no longer accessible, this made Tsukasa panic because he could no longer transform into Kamen Rider because the power of his Ghost Demon Damashii Rider was gone and his Neo Decadriver also badly damaged. Tsukasa could only resign himself to his current fate, and that's when he met Aether who was walking alone in the area, it was known that Aether had just bought a large bag of candy from a nearby local village. Aether, who knowing Tsukasa's condition, offered to repair Tsukasa's Neo Decadriver and while waiting for Tsukasa's Neo Decadriver to be repaired, Aether gave him a device called Neo Decadriver II Launcher, where when the Launcher was triggered, the Launcher would automatically summon the Neo Decadriver and the Ride Booker too. Tsukasa is also very grateful to Aether because he wants to help him, and as a sign of gratitude, Tsukasa also bought Aether an Ice Cream which is very famous in that village.

A week passed, Another Decade, who had not yet recovered, decided to attack Liyue again to lure Tsukasa out. Another Decade immediately went to Liyue with his Aurora Curtain and started to attack there. Liyue City Center at that time had begun to be ravaged, many civilian and military casualties as a result of Another Decade's ferocity. As a result of this, Ningguang finally ordered Zhongli and his Adeptus to immediately stop Another Decade. Another Decade who already knew about it immediately attacked to divert them all so that they were separated, and sure enough, this attack managed to make Ningguang, Zhongli with his Adeptus, and the Guards separate from each other, and at that time Another Decade was about to make Ningguang who was in the middle of the city center alone as his hostage. Before Another Decade approached Ningguang to take her as a hostage, unexpectedly at that time Tsukasa immediately came and challenged Another Decade to a fight. Another Decade who saw this laughed, and thought that if Tsukasa is too much style, he wanted to fight him even though he didn't have the power to turn into a Rider anymore, he already knew that Tsukasa had also lost his power to become Kamen Rider Ghost Demon Damashii Rider, and he also said that Tsukasa came there just to die in style. Tsukasa who heard that also laughed and he took out his Neo Decadriver II Launcher. He finally activated his Neo Decadriver II Launcher and immediately summoned the Neo Decadriver and Ride Booker that had appeared on his body. This makes Another Decade shocked because Tsukasa should no longer be able to become a Rider because his Neo Decadriver should have been damaged and he has lost his power to transform into Kamen Rider Ghost Demon Damashii Rider. Tsukasa explains to Another Decade that his Rider's power is from his existence itself, so even if he loses his ability to become Decade he will still gain the power to become Decade somehow or from where it came from, which is actually because Aether made a new device for Tsukasa, it turns into Decade which can also later become Tsukasa's backup device to become Decade. In short, Tsukasa turns into Decade and starts fighting Another Decade with the "Hit & Run" strategy. Here Decade tries to drain back the power of Another Decade before fighting it directly by diverting it by changing form/becoming another Rider Form such as Kamen Rider Agito, Kamen Rider Blade, Kamen Rider Zi-O, Kamen Rider Zero-One, Kamen Rider Ex-Aid, and Kamen Rider Kabuto.

After successfully overwhelming Another Decade and draining his power back by half, Decade returns to his base and begins to fight face-to-face with Another Decade. In this battle, their strength seems to be balanced until the final moment comes where they both will do their respective Rider Kick finishers. Another Decade launches his very destructive Dimension Kick attack and Decade also launches a Dimension Kick which he combines with the power of The Leviathan to offset Another Decade's Dimension Kick, and finally, they do a Rider Kick collide. In the end, Decade by exerting all his strength, Decade finally managed to win the Rider Kick collide and managed to defeat Another Decade, which is finally, Another Decade is killed and his body disappeared and turned into particles. Finally, after Tsukasa won the fight, everyone in Liyue who saw the fight cheered and considered Tsukasa as a hero after that incident, Tsukasa got a promotion to be part of the government and politics in Liyue by Ningguang's recommendation. Finally, Tsukasa became one of the government figures in Liyue and became one of the Great Commanders for Liyue's troops as the Great Commander of Liyue Special Investigation & Intelligence Division, with the rank of Shaojiang or Major General.
