Sakurai Keiwa is the deuteragonist of Kamen Rider Geats. He participates in the Desire Grand Prix as Kamen Rider Tycoon.
Keiwa is a 22-year-old college student in search of employment. Despite his struggles to get a job, Keiwa takes up volunteering at his favorite tanuki soba restaurant and thinks about others before himself. He wishes for world peace to be achieved.
His older sister Sara (25) is his only relative who looks after him. They lost their parents sometime before the start of the series' events. Their parents were Sakurai Shigeru (52) and Sakurai Yukino (51).
From his Desire Card, Keiwa initially wished for world peace. After his return to the DGP in episode 17, Keiwa wishes for the revival of all deceased victims of the Jamato and the DGP.

Trivia
Tycoon's name is probably an anagram of Tanuki.
Keiwa's name is very similar to "heiwa/peace". His personality has a tendency towards pacifism/peace.
Bujin usually uses the kanji (武人) and typically translates to "military man, soldier". However, Keiwa's sword is also named Bujin, which means "military sword" because of its kanji (武刃).
The device call says "Black General", despite "Shogun" being a better fit for Tycoon's Japanese theming.
