Hentai Ouji to Warawanai Neko.

Yokodera Youto is a boy from a local school academy whose mind is focused on his “carnal desires” — the only problem is that no one recognizes him for the pervert he is! When he hears an urban legend about a stony cat statue that can grant his wishes, he prays that he'll be able to speak his perverted mind wherever and whenever he needs to. Just wait and see how this stony cat grants his wish! (Source: eManga) Note: Includes chapter 0 and 2 extra chapters.
