Nekomura the cat has found another place of employment. The same Nekomura the cat (4 years old) you know from "Kyou no Nekomura-san" gets to work once a month at "Casa Brutus" editorial department. There, he saw and heard the whole of the story for the first time. And so, because of Casa-san of the slightly eccentric editorial staff, Nekomura-san is doing his best this month too.
