Boku no Lucky Star

As a member of a wolf clan, Kiyoto uses his human form to "emigrate" in order to join an idol group and find himself a bride!

Kiyoto works hard in the lessons while hiding his secret, but on the night of a full moon, he can't hold back his instincts and ends up pushing Motoharu down on the bed...!
