My Little Inferno

Hitoshi Arai is just an average college student with a mediocre life. During high school, he was bullied for being fat and got stressed and anxious easily. He had hoped that college would give him a fresh new start, but he remains his ordinary lone self.

One night on his way home from his part-time job, Hitoshi accidentally bumps his bag of groceries into a car. He immediately inspects the car to see if he left any scratches while internally musing about Aladdin's story. He is surprised when the trunk of the car pries itself opens, revealing an intimidating figure of a man who proceeds to take advantage of Hitoshi by letting him stay at his home. Intimidated and scared, Hitoshi does what the man wants. The man introduces himself as "Mah" and thus begins complicating Hitoshi's ordinary life.
