Kamisama no Youjinbou

"That won't help you be a good rabbit!"

In the early Meiji era, a samurai who was suppose to have died during the Battle of Hakodate wakes up in a strange shrine. There, he finds a small, fuzzy boy who calls himself a god. The god tells him that he needs training to fulfill his wish to be reincarnated as a rabbit, which he doesn't remember wishing for...?　This is the start of a Japanese-style supernatural tale between a former samurai and a small god!
