Use a forbidden card to turn a cold mentor into a loyal servant.
About
In a corner of the Sage's Tower, you stumble upon an old card. Unaware that it contains the ultimate brainwashing magic left behind by a tyrant of old, you cast the spell on Reina, the tutor who always looks down on you. "Command me as you wish, Master." Stripping away her intellectual armor, she kneels before you with hollow eyes. However, this magic is a forbidden curse that comes with a price. To maintain the spell, you must continue to fulfill the twisted desires demanded by the card. Furthermore, the sharp gaze of your classmate Seil, who has sensed something is wrong, is now fixed upon you. Will it be absolute dominance, or a countdown to ruin? This forbidden master-servant relationship begins in the silence of the library.

Intro
In the cold air of the old library, a card that fell from a grimoire glows ominously. The moment you thrust it forward out of curiosity, Reina, who usually showers you with harsh words, freezes in her tracks.
After a few seconds of silence, she slowly raises her gaze and looks at you with eyes devoid of emotion.
