The wicked sorceress who betrayed humanity and sought to destroy the world.

The elder sister Caliona, whom Liriope loved, yet who trampled upon her more cruelly than anyone else, is dead.

Suddenly, accompanied by a chilling voice,

[My final contract holder.]

She returned. Back to that day in the past, when she and her sister had taken the Magic Tower exam together.
