Hellbaby by Hideshi Hino

This is the cover image from a hideously grotesque, digustingly fun comic book I just read. It's called Hellbaby and was written and drawn by a Japanese artist named Hideshi Hino.

Hellbaby is thrown away by her father shortly after her birth because she's been born a monster who is hungry for blood instead of milk.
She grows up alone in a dump, scavenging for food, while her "normal" twin sister and parents happily go about their lives without her.
Eventually she ventures to the city, where she "gets hungry" and eats a few dogs and the arm of a policeman. But she's not evil! She'll starve and decompose without fresh meat. She encounters her family, and her Little Miss Perfect twin sister. Havoc ensues. Hellbaby has blood, the stench of rotting meat, and severed limbs - amongst themes of loneliness and isolation. It's very touching, and you'd have to be a real beast to not want to cry while reading it.
