When lazy, erotic-game loving Mahiro Oyama is transformed into a girl by his younger scientist sister’s experiments, he becomes determined to change back, only to recognize that with his new opportunity, he may want to turn his life around.

Wakana Gojo is a high school boy who wants to become a kashirashi–a master craftsman who makes traditional Japanese Hina dolls. Though he’s gung-ho about the craft, he knows nothing about the latest trends, and has a hard time fitting in with his class. The popular kids–especially one girl, Marin Kitagawa–seem like they live in a completely different world. That all changes one day, when she shares an unexpected secret with him, and their completely different worlds collide.
