Lillet Blan was thrilled with excitement. She was invited to a Magic Academy where only the talented could enter. The legendary wizard and the headmaster of the Magic Academy, Gammel Dore, the one who defeated the Archmage. And the Silver Star Tower which is the school campus that once destroyed Archmage's castle. The tower was full of unsolved mysteries and dangers, and people who had their own speculations.

On the fifth day after Lillet opened her grimoire and began her path to becoming a wizard, a terrifying disaster struck the academy, and everyone in the tower is dead. Except for Lillet who had traveled back in time without knowing why... Will Lillet come closer to the truth by reliving the five days before the tragedy?
