Anime XXX - Oni Tensei Episode 3

Legend has it that tattoos may come to life when they're perfectly drawn. Reiko Kure is a female investigator who is investigating a bizarre murder. Only the peaceful Ema Nozomi remained after some big beast brutally massacred thirteen members of the Mafia. In order to keep Ema safe, she is placed into protective care. Nevertheless, she kills and rapes all of the men and women who remain in her group. All that's left is Ema's weird tattoo design, which properly depicts a monster.
