Kira is a serial killer, characterized as highly egocentric and psychopathic, with a few obsessive-compulsive tendencies. He is also a hand fetishist.

His stand is Killer Queen, it has an alien/catlike appearance and red eyes. Pinky skin tone, strong muscle build. It can turn whatever it touches into a bomb that he can detonate whenever he pleases. 

Longs for a peaceful and quiet life. Never wants to stand out, trying to keep himself hidden.
