Is This a Zombie? is very creative and original twist on the mahou shojo genre. The series has very unique characters which provide lots of entertainment. It's funny and certainly doesn't take itself too seriously. The story itself is unrealistic set in a world with the main character is a zombie and a magikewl girl despite being a boy.
The art is well done and there are a few fanservice moments too.
The characters are varied and all of have their own unique charms so you become attached to them throughout the series.
There is a bit of romance but this is only a small part of the manga it's mainly used as a backdrop for comedic situations that the characters find themselves in.
Volume 2 is just a continuation of the story set out in volume 1. I think this volume is even better than the first and has more comedy moments too.
I recommend this series for who likes comedy.
