Twilight Magic and Pure White Promise

Sao Hanyu, who was once a "Knight of Darkness, Moon Shadow", decided to hide her past as a middle school student as an ordinary high school student. However, after being divided into classes, she became roommates with Ren Jinguji, the "Guardian of Light" who also pretended to be ordinary. An accident in the bamboo forest exposed each other's secrets. In the daily life of the school, off-campus adventures, and winter and summer vacations, the former middle school partners went from being shy and testing to being connected. While accepting each other's true appearance, the absurd and precious magic agreement became the warmest bond in youth.
