The Japanese Cannibal Murderer

He murdered a woman because he wanted to eat her bottom, breasts, and thighs. The police caught him but set him free.  The free man who happens to be a cannibal + murderer then turns in an ADULT FILM ACTOR.  THIS IS A WILD STORY.  I can't even write a summary without wanting to pull out my hair in confusion.  And guess what? He's a free man today.
