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. 
Jealous of Alice and Kyô's feeling for each other, Mayura embraces the forces of the dark nether world she is trapped in and ventures to use the negative power of the Maram Words. Sibling rivalry reaches new heights when the Seno sisters are pitted against each other armed with the power of words!
