— DiEnd, concerning treasures
Daiki Kaito (海東 大樹? Kaitō Daiki), better known as Kamen Rider DiEnd (仮面ライダーディエンド? Kamen Raidā Diendo, Masked Rider Diend), is a master thief and Kamen Rider hailing from another universe. He is considered the rival of Kamen Rider Decade, supported by their many battles against each other.
Daiki lived in his own world, where Kamen Riders were considered enemies of the state. He worked as an officer serving the evil Fourteen, and hunted down Riders and turned them into the authorities for reeducation. Eventually, Daiki captured the leader of the Riders, Kamen Rider Glaive, who turned out to be Junichi Kaito, his brother. With this revelation, Daiki learned Fourteen was the true villain, and lost his self-confidence, and set out to correct his mistakes. He stole the DiEndriver from Dai-Shocker, and took up the mantle of Kamen Rider DiEnd and became his world's new most wanted Rider.
Decade, the 9 Worlds, and Beyond
Eventually, DiEnd left his world as a wanted criminal, and journeyed to other worlds in search of treasures, to fill the void left by his brother's brainwashing at his hands. In the process, he crossed paths with Hikari Studio, a group of world travelers seeking to save the multiverse from collapsing upon itself and stopping Dai-Shocker, lead by a Kamen Rider known as Decade. Decade often got in the way of DiEnd's heists, quickly becoming a thorn in Daiki's side. While DiEnd did on occasion help Decade, it was mostly out of honor and similar interests.
Return to Home
At some point, Hikari Studio arrived in Daiki's world, where DiEnd is a wanted criminal. The world was peaceful, yet had the dark secret of society being controlled by Fourteen and his Darkroaches. DiEnd was pursued by his former allies Larc and Lance for being why Junichi was brainwashed, but they eventually banded together to find and destroy Fourteen, who had kidnapped and brainwashed Yusuke and Natsumi. Decade and DiEnd then teamed up and used Kaito as bait to lure Fourteen out, and then ambushed him, with Decade managing to land a fatal blow on Fourteen, ending his reign of terror and freeing everyone from being brainwashed. However, Junichi, as Glaive, attacked DiEnd, revealing he never was brainwashed and served Fourteen willingly. Decade kept the other Riders back so DiEnd and Glaive could have their duel, but the duel ended in a tie when Decade stopped it. Junichi proclaimed he would become the next Fourteen and left, proclaiming that his brother was dead to him.
DiEnd in Gensokyo
DiEnd later followed Hikari Studio into the RPverse, ending up in Gensokyo. DiEnd had heard rumors of the Hourai Elixir, an elixir that could make the user absolutely immortal, and decided it was to be his next treasure. DiEnd entered Eientei and attempted to rob Eirin Yagokoro, but was driven off by her, along with Kaguya Houraisan and, ironically enough, Decade. DiEnd escaped without the Elixir.
Later, DiEnd teamed up with Decade yet again to face down Hoopa, who had entered his unbound form. The two, aided by alternate versions of themselves, fought Hoopa, but even with both Decades in Complete Form, they were overpowered. It was not until one of the Decades used a Final Form Ride on Reimu, followed by the intervention of Yukari Yakumo herself, that Hoopa was defeated. DiEnd then stole the Prison Bottle, seeing it as a treasure of great value for how strong it made Hoopa, but gave it to Yukari the next day, feeling he "owed" her.
Daiki is a man who has no true goal other than to collect as many treasures as possible. He does this to fill the void left by what he supposedly did to his brother, and later to fill the void left by his brother leaving him. He tends not to help people unless it serves his own interests, and will not hesitate to hurt anyone who gets in the way of said interests, even if they are weak or innocent. In the end, he firmly is allied with no one but himself; mistaking his assistance as an alliance is a mistake no one should make, lest they truly want to assist him in his goals.
Do not take this as him being a villain, however. As his past shows, DiEnd hates those who take freedom from others, as Fourteen did with his world, and he will not hesitate to kill anyone who robs people of their freedom.
Daiki also has his soft side, and is willing to help people if he feels he "owes" them in some way. He also has a small soft spot for children, often acting as a big brother to children in need, although he denies having such friendships with children.
