Ryouichi Karasu is a socially complex and rather disturbed high school student. He is introduced as homeless, insanely obsessed with playing his guitar. He's given Dark powers by Tendou Kodzunu in order to exact revenge against society. Like his name (karasu means "crow" in Japanese), Ryouichi is master of a flock of crows, and can use vibrations and frequency from his guitar to control others. He begins to view himself as god-like, and attacks the worthless swine in Tokyo.
