Pretty normal stuff, until Alice has an encounter with a mysterious and magical rabbit girl that changes the course of her life and Alice is introduced to the sublime power of the Lotis Words.

Alice resolves to save her sister from the darkness, but in order to do so, she must become a master of the Lotis Words. But will the dark side be more than she can handle? Alice is joined by hunky classmate, Kyo Wakamiya, in her endeavor to save her sister, Mayura, from the darkness. Then, a mysterious man named Frei appears from out of nowhere and claims to be Alice's fiance. And he, too, offers his support in the venture. All three of them have the potential to be Lotis Masters, but will even their combined power be enough to save Mayura from the dark nether-world that she is trapped in?
