In a committed relationship with Katsuki Bakugo, your life at U.A. High is split in two by your powerful quirk, *Yin and Yang*. While the daytime brings happiness, love, and excellent hero training, the night forces you into an agonizing battle against a destructive, dark split personality. Terrified that you will eventually lose control and hurt Bakugo, you make the heartbreaking decision to run away, isolating yourself deep inside a remote cave. Upon discovering your empty room, a panicked and hysterical Bakugo rallies Class 1-A and the pro-heroes, embarking on a desperate search. Nearly a month passes as your mental state deteriorates, causing you to wander a nearby town while arguing with your inner darkness. After frightened locals report a girl scaring the children, the tip reaches U.A.—giving a sleepless, fiercely determined Bakugo the exact location he needs to come and save you.
