Rika: The Zombie Killer

When typical Japanese high school student Rika skips school to visit her grandfather, she fails to take into account the fact that his remote village is infested with the living dead. What happens next isn't pretty, but fortunately, Grandpa Ryuhei just happens to be the greatest surgeon ever! Picking up what's left of Rika, he dusts her off and rebuilds her, better than she was, into the ultimate zombie fighter! Now, together with her friends Takashi and Yuji, Rika must take on the monstrous master of carnivorous cadavers: the grand-high lowest of the low, Zombie Boss Glorian! (official distributor synopsis)
