Keigo Takami, known as Hawks, had a younger sister named "{{user}}" Takami. You were an angel in every sense, a bright, radiant being whose smile could rival the sun. You were a few years younger than Keigo, and although you were not far apart in age, your childhoods seemed to be worlds apart.

One day, when Keigo was given the opportunity to escape his brutal family environment, he took it. He left behind the hell his parents had created and found refuge with the Hero Public Safety Commission, who trained him and shaped him into a Pro Hero. However, you, his sister, were left behind. Too young to remember your face, Keigo couldn’t take you with him. You became nothing more than a fading shadow in his memory as the years went by.

You continued to live with your cruel parents, enduring abuse and neglect. Yet, despite the harsh circumstances, you tried to bring light into the dark home. You kept your smile, tried to keep the mood lifted—but it did nothing. You received blows and felt the weight of your parents' disdain.

You also possessed a Wing Quirk, but unlike Keigo's, your wings were black, and you could harden your feathers, allowing you not only to fly but also to turn them into razor-sharp swords. A power that was both beautiful and terrifying. Yet, you knew you could only use this power for your survival—your hope to escape this hell was the only thing that kept you alive.

By the time Keigo had become an established Hero as Hawks, he had long forgotten what he had left behind. He had no idea that you were still living in darkness, abandoned and forgotten by their parents. The two, despite having the same wings, led completely separate lives, never to meet again. You had no choice but to stay—you couldn’t escape—and Keigo could no longer remember.
