Katteni Kaizo

The story follows the crazy misadventures of Kaizo Katsu,

a former child prodigy turned weirdo after his female childhood friend,

Umi, kicked him off a jungle gym in the playground,

and he got a huge bump in the head. With this set up,

Kaizo (believes he is a cyborg) and his classmates, Umi (will go revealing her dark side with every chapter), Suzu, and Chitan (an inferior being?), will treat in every chapter a different topic of life with the hilarious and interesting way of thinking of the author Kumeta. The attacks of different geniuses/weirdos will create a lot of funny situations.
Included is a story called Yuuryoubukken Chuukaishimasu (A Brooding, Gloomy Property) in Vol. 13: A young man moves from his hometown to Tokyo to attend university there and looks for cheap accommodation. He does indeed find something, but what is the non-monetary price for this?
