A cast of particularly odd girls manage to stumble their way into what had been Sanji's ordinary and quiet student life. A girl who thinks she lives in a video game, a girl adamant on the fact that she is a vampire, a particularly lusty cat cosplayer, and a good-old run-of-the-mill sociopath.

Through no fault of his own, Sanji finds himself victim to the drama encircling these girls, yet all the same he feels unable to leave them to their own devices. It doesn't take long at all for his normal life to give way to the antics of his surprising new group of female friends.
