He eventually gets tired of his world and seeks to find a new one, along the way he finds the Diendriver and ends up working for Narutaki and there’s no real explanation for any of this.
Video Game appearances Kamen Rider Diend appears as a Second Rider in the video game Kamen Rider: Battride War.
Personality
Daiki is a mysterious young man who is portrayed as being cheerful to the extent of being annoying to those around him, but becomes serious in battle and sees material objects as more important than anything else. Narutaki, aware that Daiki is Diend, avoids getting in his way. He also appears to know about Tsukasa's past, referring to sea cucumbers as being something Tsukasa had always wanted to taste. He travels from A.R. World to A.R. World, stealing what he refers to as "treasures".
It is revealed that he comes from an A.R. World (referred to as the "World of Diend") where he was an officer who served the evil Fourteen who has deemed Kamen Riders as threats to the public peace. Daiki hunted them down and turned them in for education until he captured the leader of the Kamen Riders: Kamen Rider Glaive. When Glaive is unmasked, he is revealed to be Daiki's older brother Junichi.
By then, Daiki learns the truth that Fourteen brainwashes people, powerless to stop him. Losing his self-confidence and seeking to undo all of the mistakes he had caused, Daiki stole the Diendriver from Dai-Shocker, becoming Kamen Rider Diend and becomes Fourteen's new most wanted Kamen Rider.
He leaves his world, traveling to other worlds and taking their treasures as a means of self-delusion until he crosses paths with Kamen Rider Decade. Eventually, he does lackadaisically accept the Hikari Studio residents as "friends", even calling Decade a "comrade", though he is not beyond abandoning them without explanation, usually for his own self-interest.

- Daiki Kaito is portrayed by Kimito Totani, who reprised his role in Kamen Rider × Super Sentai: Super Hero Taisen.
- As Kamen Rider Diend, his suit actor in Kamen Rider Decade was Eitoku, who has been the suit actor for the Secondary Riders of the "Neo-Heisei era" from Accel to Meteor. In Super Hero Taisen, his suit actor was Ryo Yokota.
- Kamen Rider Diend name comes from the English words "die" and "end", as well as "the end".
- Daiki's surname is a homophone of the Japanese word kaitō, a role he fulfills in Decade.
- In some materials in Decade, Daiki's surname is spelled in English as "Kaitoh" rather than "Kaito"; this is considered an acceptable alternative Romanization for the long "O" sound.
- Unlike Kamen Rider Decade, Daiki can't change into any of the past Riders in the same way he could. The only time he became another Rider was when he briefly wears the G3-X armor.
- Exactly how and when Kaito stole the Diendriver from Dai-Shocker was never clearly stated, but many fans believe that when he ran away from his world, he stole the Driver while traveling and stealing treasure.
- He is similar to Basco ta Jolokia from Kaizoku Sentai Gokaiger, as they both can summon Riders/Sentai from a device. However, what separates Daiki from the likes of Basco is that he doesn't have a monstrous form and that he's also somewhat redeemable.
- As shown in Super Hero Taisen, he is also similar to Joe Gibken (Gokai Blue), in that they are both blue-colored heroes and Daiki has a close relationship with Tsukasa just as Joe as a close relationship with Captain Marvelous (Gokai Red). However, Daiki is more of a rival to Tsukasa while Joe is much more loyal to Marvelous.
- He is the second Rider after Daisuke Kazama to use a gun to transform into a Rider.
- Coincidentally, both Daisuke and Daiki are Cyan-colored Riders.
