Is this a Zombie? is a 2009 light novel series written by Kimura Shinichi, illustrated by kobuichi and muririn, published by Fujimi Shobou, and later turned into a 2011 anime series by Studio Deen.
Aikawa Ayumu is a high-schooler murdered by a serial killer, only to be revived as a zombie by underworld necromancer Eucliwood Hellscythe. Currently he lives with Eucliwood, Haruna, a prideful Masou-Shoujo (magically-equipped girl; a pink chainsaw, in her case) whose powers he accidentally stole, and Seraphim and Yoshida Yuki, a pair of vampire-ninjas from opposing clans.
