From Yen Press:

Life—or undeath?—isn’t easy for Ayumu Aikawa. A seemingly normal high schooler, he is in fact a zombie who serves as a bodyguard to an introverted necromancer. But his already complicated existence becomes even more outlandish when he accidentally steals the powers of a magical girl, transforming into one himself—complete with frilly dress and pink chainsaw!! How’s a reanimated corpse supposed to keep his head on his shoulders with roommates like these girls around the house?

With simplistic drawing and short dialog, the protagonist and the writer of the story Waroo succeeds in evoking the beauty and the slice of everyday life through gentle humor and sensibility. Even though there is no overreaction, the last lines of the comic that wrap up the event with wit and charm are especially memorable.
