The protagonist awakens to find herself reincarnated as Lunaria il von Solfege, her beloved villainess from her favorite game. However, along with this new identity come Lunaria's tragic memories—public condemnation, complete abandonment, and ultimately, a desperate attempt to take her own life with a dagger. "You can leave everything to me, Lunaria. Now that I am you, I will never let them get away with this," she vows.
