His father is also a retired Japanese Army Commander who currently serves as Prime Minister of Japan.

Little Daiki has been taught hard militarily by his father, his father wants Daiki to become an army just like he was before and severely limits Daiki's freedom when doing anything. Different from his father, his mother Sakura Kazaki, taught Daiki more gently and freely which is inversely proportional to his father's upbringing, this makes Daiki more like his mother than his father, even so Daiki still respects and loves his father as much as he respects and loves his mother, because He considers that the two upbringings are balanced upbringing and will be of great benefit to his future.

When he grew up, Daiki became a very liberal person and he also became an adventurer, he often traveled back and forth around the world and looked for challenges that he thought were interesting, and this of course made his father annoyed because Daiki ended up being someone he considered too liberal. Because of this, his father was immediately very angry with him and considered Daiki as a failure, his father insisted that he immediately enter the military academy but Daiki refused, his father continued to force him even to the point of threatening him if he still refused his father's orders to enter the military, and Daiki who can't stand it anymore and finally invites a duel with his father, if the father wins, then he will follow all his orders, and if he wins, then the father must let Daiki do and determine whatever he wants, and his father agreed to this. In short, finally, a duel was held where they performed a Karate duel in a large hall near the palace, and this duel was being watched by many people even by the Emperor himself. The duel begins and here Daiki is very overwhelmed in facing his father, his father continues to beat him hard without giving him a chance to attack him back, and in just 45 seconds, Daiki immediately falls. Not long after, Daiki felt an aura of strange power within him that immediately made him fit in again, he finally asked for a rematch duel with his father and his father agreed to this. The duel started again and again the father continued to dominate the fight by beating Daiki all out, but Daiki still persisted until 6 minutes later, the audience there started to get excited about it where Daiki was starting to feel pain and asked to surrender to his father, but his father did not care about it where his father wanted Daiki to fully knocked out as a lesson so that he would not fight his father again. Daiki kept shouting asking his father to stop and asking the people there to stop his father. The people there began to panic and asked his father to stop the fight, some of them even tried to enter the duel arena to break them up but were restrained by his father's aides. Unable to take it anymore, Daiki began to scream loudly, and unexpectedly, Daiki with the power of a strange power aura within him, instantly knocked his father out with the power of telekinesis which also instantly knocked his father unconscious. The people and the Emperor who was there watching the match start to be shocked seeing this, as were the aides of the father. Feeling guilty and scared, Daiki finally decided to go and run away from there, where his father's men tried to chase him, but they were stopped by the Emperor to stop chasing Daiki.

First Meeting with Tsukasa Kadoya and Becoming Kamen Rider
Daiki, who was still afraid of what had happened, started to run far away from the palace without a direction which after 3 hours of non-stop running, he arrived near a mountain where he decided to rest there. While he was resting, he was also visited by a mysterious man who claimed that he could change Daiki's fate by honing Daiki's superpowers. The mysterious man also invited Daiki to come with him, and Daiki agreed to this, then the mysterious man began to open a dimensional curtain which is a portal and they finally entered the curtain. After entering the curtain, they were immediately in a large mansion which turned out to be the residence of the mysterious man. The mysterious man introduced himself as Tsukasa Kadoya, and he was not alone, he was with two other friends who also lived there, they were Daiki Kaito and Yusuke Onodera. Tsukasa explains, if he feels a tremendous power within Daiki, he says that with that power, he has the potential to become a Kamen Rider. Daiki, who is confused about what Kamen Rider is, begins to ask Tsukasa about what power he has so that he can perform telekinesis attacks and what Kamen Rider is. Tsukasa also explained what Kamen Rider is and he also explained that the power that Daiki has, is a base power of a Kamen Rider, which the power has a link with the power of the same Kamen Rider as himself, namely Kamen Rider Decade. For that, Tsukasa finally gave his old Decadriver to be used by Daiki to test whether he could transform into Kamen Rider Decade or not because only people who have interdimensional power resonate with the base power of Kamen Rider, especially the base power of Kamen Rider Decade, which can transform into Kamen Rider Decade, which Tsukasa himself felt that Daiki already had a base power from Kamen Rider Decade. Daiki finally tries to transform into Kamen Rider Decade and finally, Tsukasa's prediction is correct, if Daiki can transform into Kamen Rider Decade with the power that is within him. But not long after, Daiki began to lose control of his power that had resonated with the power of Kamen Rider Decade, Daiki can't control his Rider Form power, which eventually made Tsukasa quickly release the Decadriver on Daiki's waist, and Daiki suddenly detransformed into his human form again. Tsukasa finally decides to train Daiki's potential power so that he can control his power directly or when he is in his Rider Form, and also to unlock his true power which according to Tsukasa, that his power is still locked inside of Daiki.
