I'm The Catlord's Manservant v.1
Izumi Yukihara, high school second year. His life is completely average - until a series of misfortunate events turn his life upside down.
As if losing his parents weren't enough, he's saddled with their massive debt and forced to relocate to a new residence.
On the bright side, the owners of his new residence offer him a chance to repay his debt... by serving cats?!
