Kyou no Nekomura-san

With the appearance of a cat, Nekomura is being employed by an upper-class family. He notices everything that goes on in the house and he does not fail to intrigue! He is very hard-working, but he can't help but poke his nose here and there occasionally, stumbling upon some secrets.
