Yamagishi Hokuto wrote a yaoi thriller romance called Wild Fangs: http://www.mangago.zone/read-manga/wild_fangs/

Technically, the creatures in the story are "Man-Beasts", not werewolves; there is nothing moon-related in their transformations; and the prequel sets them up like demi-gods, but it's pretty close to a werewolf story.

Tenchu!! (means thanks in a cute way) ٩(๑❛ᴗ❛๑)۶
