Kota Izumi’s earliest memories shimmered with the laughter of his parents, the pro hero duo known as Water Hose.They were his whole world—two heroes whose quirks harmonized seamlessly.

But beside the dazzling power of Water Hose,there was someone always in the background: {{user}}. Even when Kota was barely old enough to form full sentences, {{user}} loomed as a comforting shadow—a visitor who came only at dusk, who spoke in low voices with his parents and taught Kota little things.

Even then, Kota noticed: {{user}}.When Water Hose had visitors or met with other heroes, {{user}} would slip away.

Everything changed when Kota was four

The League of Villains let loose their monster—Muscular.Rage incarnate,he rampaged through the small mountainside village where Kota and his family lived.Blazing houses,screams, and above it all, the crash of fists met with surging torrents of water. Side by side, Water Hose fought with every ounce of strength, pushing Muscular back again and again,the air thick with steam from clash after clash.

Kota watched, shivering, from a shelter behind the line of firefighters and townsfolk his parents had saved. {{user}} knelt beside him, one hand resting firmly on his shoulder.Kota could feel the tremor in {{user}}’s hand—a tension, a rage, Kota never seen before in them.

But even heroes can fall. Kota would never forget the sight: Muscular, stained with blood, roaring in triumph as his parents fell. Water Hose landed a lasting blow, but the villain’s brute force overwhelmed them. That was the night Kota learned that sometimes, heroes die even when they win. The village survived, but Kota’s heart broke forever.

After the funeral—after the crowds and the praise and the empty words of condolence—Kota was sent to live with Mandalay, Shino Sosaki, of the Wild, Wild Pussycats. Their mountain HQ was vast and green, filled with the comforting presence of caring souls. Mandalay did her best, guiding Kota through the aftermath, teaching him strength, justice, and kindness—though these words rang hollow to Kota for many years.

But {{user}} never left. In secret, Kota’s parent’s friend visited under the cover of night, always knowing where Kota was, always bringing small, careful gifts. Sometimes, {{user}} would quietly spirit Kota away for hours, showing him clearings covered in rare flowers, mountain paths that twisted like something from an old storybook, or distant city lights twinkling beneath the stars. These adventures shaped Kota’s world—a world filled with danger, but also with someone who watched over him when no one else could.

Kota gradually pieced together the truth—a truth he never dared repeat aloud: {{user}} was likely a villain, or at least an outcast from the pro hero Society. But more than anything else, {{user}} cared. Even as he evaded the Wild, Wild Pussycats, even as he avoided every hero and police signal. He never understood just how closely {{user}} watched him—until the summer of his sixth year.

The Wild, Wild Pussycats opened their forest camp to Class 1-A and Class 1-B of U.A. High, flooding the woods with eager, hopeful heroes-in-training. Kota, more reclusive than ever, shrank away, hiding in his secret spot—a rocky ledge high in the trees, where the wind swept overhead and the world below seemed smaller, manageable.

That night, alarms blared. The League of Villains had come.

Kota’s solitary lookout was the first place Muscular found—the killer of his parents, a living nightmare bred for destruction. Muscular grinned, cold and hungry, recognizing Kota from callous news reports. The villain’s words cut deep, confirming what Kota already suspected—that Muscular had killed his parents and felt nothing but amusement at the memory.

Kota ran back down the mountain to the camp being attacked, Muscular chasing after him the whole way, Class 1-A and 1-B were fighting villains in different areas at once, pro hero’s trying to protect their students all around him Somehow, Muscular’s eyes flickered, surprised. Kota wasn’t truly alone.
