A teenage girl Maze wakes up in an unfamiliar world — her bedroom having been torn from the rest of her house. She desperately tries to make sense of this strange world when suddenly a little girl named Mill hugs her and starts calling her big sister. As it turns out Mill is a princess in need of protection by Maze. And if that was not bizarre enough, Maze now turns into a man at night, and becomes big sister/brother to Mill.
Maze meets up with all sorts of strange friends, most of whom are attracted to her. And male Maze, in turn, falls for most of the female cast. These friends wind up protecting Maze and Mill, helping the latter to eventually reclaim the throne.
