Alice Seno seems like a normal girl in high school. She's a bit shy, she's got a crush on a boy named Kyô, and she's got an older sister who is more popular than she is...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. 
Kyô Wakamiya joins Alice Seno's endeavor to save her sister, Mayura, from the darkness. From out of nowhere, a mysterious handsome man named Frei appears to claim Alice as his fiancée and he too, offers his support to save Mayura. All three of them have the potential to be great Lotis Masters, but will even their combined power be enough to save Mayura from the dark nether world that she is trapped in?
