Boku wa Oneko-sama no Geboku desu.

Izumi Yukiharu is a second-year high schooler. After suddenly losing his parents one day, the only thing he's inherited is a 50,000,000 yen debt?! Without a place to live, Yukiharu stumbles into a certain residential home. To repay the debt, he's designated as "their Catships' catservant"…?!

The curtain raises on a somewhat peaceful, slapstick, pampered-cat comedy!
