Remember those nightmares you had as a child, where your toys came to life? That's the reality that Jun Sakurada suddenly finds himself living in when Shinku arrives in a box. She's the first of several magical Rozen Maidens to invade the secluded life he has made for himself since refusing to attend school anymore and living the life of a hermit. Worse, he finds himself magically bound to Shinku, his life force powering hers, and she's not too crazy about the way he's been living his life.
