Ichiyo Shimamura - 島村一葉

[Mitsuha's](https://anilist.co/character/368777) older brother. A man who fully transforms into Kamen Rider V3. He has no doubt that V3 is the strongest rider, and in order to embody that identity, he has mastered all kinds of martial arts and has high combat abilities. Because "his soul is V3," he does not need to use tools to transform when fighting, and instead faces evil with just his body.
