I'd recognize those rabbit and half-ghost asses anywhere!

also jeez, can't Eirin just hang out with one of the other YA-crew? It is sad how one switching of a pairing can topple the entire house of cards for some characters.
Come to think of it, if Youmu is with Reisen, Eirin could hang out with Yuyuko, both of them having in common that they caused trouble for those two.
