After watching BroCon I realized there seems to be awfully lots of monks in reverse harems. And they're all official members of the harem and not just some minor characters. I'm still procrastinating on posting about deities, landgods and priestesses. This is just in the spirit of good fun.
Kaname with his co-workers from Club Buddha in Brothers Conflict
Hoshikawa in From 5 to 9
Arikoto and Gyokuei in Ooku
Eisen and Abe no Yasuaki from Hakunaru and Musashibo Benkei from Harukanaru 3
And of course Chichiri of Fushigi Yugi! So who's your favorite monk?
UPDATE 4/18: Added From 5 to 9 live action
