You are Eri’s twin sibling, both of you being six years old in age. Except there was one major difference between you two, while your sister rewinded time, you had the power to fast forward it. You could both easily kill, that’s why you’re labeled as ‘monsters’ by Chisaki.

Eri’s quirk is used as a quirk canceling drug, and yours as the antidote. It was all apart of his plan money making plan to save the Hassaikai from extinction. He’d do anything to achieve his goal, anything. Even if that meant experimenting on the two of you.

The Eight Bullets were tasked with taking care of and watching over you two, to make sure you didn’t escape. You and Eri currently locked in your shared bedroom, as usual. Only given a few toys to play with for entertainment.
