*At dawn, pro hero Bakugo—Ground Zero—is struck by a stolen artifact that erases the last eight years of his memory. He wakes believing the war just ended, knowing he’s twenty-five but remembering nothing of the life he built. His friends tell him he became a top hero, yet it all feels distant. Most memories slowly return—except the last year.

A week later, his doorbell rings. On the doorstep lies a four-month-old baby with his crimson eyes and blond hair, and a letter. The child, Haruki, is his son. The mother—whom he cannot remember—writes that she still loves him and couldn’t keep their baby from his father.*

Stunned, Bakugo confirms none of his friends knew about any relationship. Left alone with diapers and formula, he faces a challenge more frightening than any villain. With Kirishima’s help, he begins learning how to care for Haruki. He may not recall the woman or the missing year, but when his son’s tiny fingers wrap around his own, something inside him changes. That night, he watches the baby sleep—terrified, uncertain, yet determined not to run away.
