- ―Daiki's boast when stealing a treasure[src]
Daiki Kaito (海東 大樹 Kaitō Daiki?) is Kamen Rider Diend (仮面ライダーディエンド Kamen Raidā Diendo?), who is one of the fictional characters and secondary Kamen Rider in the Kamen Rider Series of Kamen Rider Decade.
World of Blade
World of Faiz
Arriving in Faiz's World ahead of Tsukasa, Daiki witnesses Faiz's battle with the Butterfly Orphnoch and was unable to catch him to acquire his Faiz Gear. When Tsukasa arrives in Faiz's World, Daiki reveals that Faiz is among the student body and warns him not to meddle in his affairs. However, as Tsukasa decides to find Faiz, Daiki gets Lucky Clover's aid by showing them the photograph that Faiz dropped during the fight under the assumption he wanted to join their group, leaving them to attack Yuri before Takumi becomes Faiz to protect her. Daiki then attempts to run away from school, but realizes that he needs to stay and make sure the belt is in proper hands.
When the Orphnochs acquire the belt, Daiki reveals his true intentions as he becomes Diend. He kills the Centipede Orphnoch before he and Decade fight over the Faiz Gear until Takumi regains it, later disposing of it. But in spite of being told Takumi had something more precious than the Faiz Gear, Daiki takes the Ride Booker from Tsukasa in an attempt to take the Faiz Gear from him. Narutaki whisks Tsukasa away to fight Kamen Rider Ryuga, but Daiki interrogates Kiva-la on the location to save Tsukasa, claiming that the Faiz Gear is what he came for as he gives Tsukasa back his Ride Booker.
However, during the Lucky Clover invasion of the Smart Brain School, Daiki returns once again to Tsukasa and Takumi's aid, returning the Faiz Driver to Takumi. After the fight, Daiki claims the Orga Gear for himself out of rubble while seeing it as the "more precious treasure" Tsukasa spoke of, leaving a little note on the painting of Agito's World as a warning not to meddle in his affairs again, which further irritates Tsukasa.

He then admits to get the last scroll from Hibiki who blocks his path and gives him his Onkaku to give to Asumu along with his final request. The next day, Daiki uses Asumu to distract Hibiki lost enough to steal the scroll, invoking the man's change into Gyuki to cover his escape. However, after reading the scrolls, Daiki returns to give Asumu the Onkaku in order to see the harmony of the three Ongekidō styles.

Kamen Rider Decade: The World of Tsukasa Kadoya ~The Garden Inside the Lens~
In the novel which is the reimagination of the TV series, Kaito is given a tragic past and is a very confused and troubled man. His entire family is brutally murdered in front of him. Out of desperation Kaito begs on his knees, hoping he’ll be spared, even going as far as to lick the murderer’s shoes. 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. Here, he has no interest for stealing treasures, but it is however dropped after Kabuto’s world.
Arriving at their final destination, the world of Kabuto, where they meet Souji Tendou, still as arrogant and confident as ever, and considers himself as the strongest Rider ever. The group enters Bistro La Salle where Hiyori Kusakabe works. Hiyori sees Kaito and Tsukasa, dressed as a ZECTroopers, claiming that the two of them ate without paying. Tendou hears this and is enraged. The three of them fight and Tendou actually beats them with only a pair of chopsticks. Turns out it was a pair of Worms that ate without paying. Tsukasa and Kaito are eventually captured by ZECT, only to have Tendou save them. Tsukasa thanks him and says that he never thanks people. Tsukasa starts respecting Tendou. For some inexplicable reason, Tendou has the Clock Up Attack Ride Rider Card and gives it to Tsukasa after he realizes that he is Kamen Rider Decade. Tsukasa uses the Clock Up card as Kuuga, meaning the Attack Ride cards aren’t restricted to their respective Riders in the novel. In the end, the Worms that impersonate both Tsukasa and Kaito have been defeated. As the fight is over the trio goes back to Tsukasa’s world.
Between all the traveling, a vampire has been attacking in Tsukasa’s world, leaving behind drained corpses. The group investigates and they find out that Narutaki is the vampire. Just like the group, Narutaki originally had his own homeworld, but abandoned it to find a new one. However, he’s been traveling for so long that his mind has been deteriorating and can barely remember who he really is. He was originally a human, but somehow in his journeys, he had lost his humanity. The Kamen Riders have a very pure energy that Narutaki seeks to consume: the Rider Cards. Thus, he sends Kaito to steal them for him. Kaito reveals his betrayal towards the team and gives Narutaki Tsukasa's 9 Heisei Rider Cards and Narutaki reveals his real form: a red-hued demon. Kaito suddenly has a change of heart, and sacrifices himself to save Tsukasa.
A few decades after Tsukasa and Natsumi's final confrontation with Narutaki, Kaito revives as an unchanged young man and reappears in front of an elderly Tsukasa. Kaito tells him it’s time to visit Natsumi’s world. There they are greeted by a young Natsumi, and Tsukasa finds himself as a young man again.
Video Game appearances
Kamen Rider: Battride War
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.
He mostly appeared as Kamen Rider Diend. Only in Episode 12 of Kamen Rider Decade, he briefly wore G3-X suit.
Kamen Rider Diend's ending theme is entitled "Treasure Sniper".

Behind the scenes
As Kamen Rider Diend, his suit actor in Kamen Rider Decade was Eitoku (永徳?), 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 (横田 遼 Yokota Ryō?).
- 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 (怪盗? phantom thief), 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.
