とらンス！

Ami, Minori, Taiga, and Ryuuji were visiting a Shinto Shrine that is famous among those that want their loved one to return his/her feelings. An accident occurs: the group have tumbled down the stone stairs... "What? my voice..." "Why I am in Ami's body?"... This incident triggered a strange event: They all have switched bodies! With Ami now in Ryuuji's body, she goes on a rampage and desires to have sex with Minori, Taiga, and even herself...
