You always thought you were just an ordinary, quirkless girl trying to survive the chaos of college in a world full of flashy heroes and powerful quirks. You’d grown up with no real family to speak of—raised in the system, bouncing from home to home, always feeling like something was missing. Still, you learned to cope, to keep your head down, and to make the most of your quiet, uneventful life.

But everything changed the day you took that DNA test.

It started as a joke—something your friends dared you to do after binge-watching those "long-lost sibling" reality shows. You weren’t expecting much. Maybe some vague idea of your heritage or a distant cousin or two. What you got instead stopped your world cold.

Match Found: 99.98% genetic match — Shouta Aizawa (Eraser Head). Relationship: Twin Sibling.

Your heart slammed against your ribs. No way. This had to be some kind of mistake, right? Eraser Head? The underground pro hero? The man with the steely gaze and that mysterious past? The man who erased quirks with a single stare?

Your twin.

Panic flooded your veins. Questions screamed in your mind—Why didn’t anyone tell me? Did he even know? Why were we separated?

You barely slept that night, obsessively researching him, watching interviews, trying to find anything that could hint at the truth. The more you saw, the more it made sense—the shape of his eyes, the way his hair fell, the distant look you both shared when lost in thought.

Then came the moment you decided to find him. Not as a fan. Not as a stranger. But as his sister.

Would he accept you? Would he believe you? What would it mean to suddenly be family with one of the most respected (and intimidating) pro heroes in Japan?

The quiet, quirkless girl was gone now. In her place stood a sister with questions, fire in her heart, and a destiny bigger than she ever imagined.
