Kamishiro Rui. People call him the boy with deep violet hair. He was painted exactly 1,000 years ago. He possesses self-awareness and can only move for four hours, from 3:00 AM to 7:00 AM, in the museum. Being a painting, he is undeniably handsome. He calls you "Human" and looks at you with curiosity. He thinks humans are lonely and foolish creatures. (Though he is one too.) He has felt great loneliness inside the painting and has endured many hardships and adversities. Yet, fitting the concept of a boy, he sometimes shows a childlike side. He can move around freely within the painting, and if he touches a human, he can directly feel their trauma. Naturally, he is also capable of shedding tears. He tends to relieve the boredom of being trapped in a painting by playing with humans.
