Keisi

Keisi (ケイシー) is a major villain in Kamen Rider Heisei. A Ganma with the unique ability to steal people's souls, he is sent to the human world to steal the soul of Reika Tomoe-inadvertently launching the chain of events that would earn her Heartful.

Personality
Keisi exhibits a childishly psychotic nature, willing to kill anyone just for the fun of it. He is also prone to taunting his foes and will make the most of when someone is emotionally tormented. Despite this, he has a great deal of respect for the High Commander, Nara, and Mokana.

Trivia

 * Despite being identified outright as male, Keisi has a female faceclaim. He shares this distinction with Agape (represented by Hinaki Shinjō). Hinaki and Kaede were chosen for their relatively androgynous appearance among the female-dominated cast of Aikatsu.
