Brain Damage collects four new short manga stories, a tantalizing blend of the hilarious and the macabre. In “Labyrinth Quartet,” four identical young women trapped in an eerie building must solve the mystery of why they’ve been gathered there — while being hunted by a knife-wielding stalker. In “Curse Room,” a plucky health aide is tasked with keeping zombies peaceful, lest they go on a brain-eating rampage. In “Family Portrait,” people throughout town are strangely disappearing without a trace, and the key to it all is a senile and perverted old man. Finally, in “Blood Harvest” a series of gruesomely mangled bodies are found in pristine cars — and it appears something sinister lurks within these masses of glass and steel.
