Leader of Innovator
Member of Parliament
On the outside, Yoshimitsu Kaidou appears as a noble governmental figure towards the world. His true self is an ambitious character for world domination by monopolizing profitable attempts to create his own kingdom. He will any means to obtain his goal, regardless of civilian casualties and will not hesitate to push the blame towards others if failure arises.
At the Tokyo Bridge collapse incident, Yoshimitsu protects Jin Kaido from the media and adopts him into his family. It is not shown how much sincerity he puts while raising Jin, as the caring side was nothing more than a facade compared to his true character.
He later advises Yagami Eiji that the Innovator are not a crime syndicate, and are an organization trying to better the world. But as Yagami walks away, he laments that his agent is starting to learn too much.
When Jin lost to Ban at the Underground Visdas Tournament, he expressed disappoint but remained the confident that the Innovator would reign supreme. He met Ban Yamano, Ami, and Kazu in person for the first time and offered the boy and his friends the chance to free his father: if they can beat him in an LBX battle. He overpowers them with his LBX Gekkoumaru and uses his Hissatsu Function: Gekka Ranbu, all three slashes eliminating Achilles, Hunter, and Kunoichi. Hunter lost an arm and Kunoichi lost a leg. He got his guards to surround them, and revealed that his other guards captured Hanzou, Mika, Ryuu, Takuya, Lex, and Rina. With everyone together for a "reunion", and Jin watching without his knowledge he taunts Lex for coming back before having his guards bring in the guest of honor: Junichiro Yamano. Takuya takes this opportunity to overpower his guard with Hanzou's help and aims a gun at his back.
After the 2050 Artemis tournament, he stands proudly in his hotel room with the successful theft of the Platinum Capsule and the Methanus GX CPU. He was confronted by Eiji Yagami questioning about the forceful methods for stealing the items, leading Yoshimitsu to believe Yagami was no longer useful on account of his rebelllious speech. Later after Yagami leaves the room, he was shot by Ren Hiyama (in the anime), with his identity replaced by an android.
