Keraku no Ou

No friends, daily beatings by bullies & even his parents have given up on Ryouichi. However, his life changes one day when a new girl transfers to his class. Chihiro is an old childhood friend, and she remembers Ryouichi. She is unaware that he has suffered brain damage from an injury he sustained while they were playing together as children. Riddled with guilt, she offers to do anything for him. Taking advantage of the situation, Ryouichi demands sex from her. Her conscience does not allow Chihiro to back out, and she agrees. Ryouichi quickly learns that he is infallible in bed, and vows to make every woman who has wronged him his sexual slave! (Source: hkdvdstore.net)
