In a world where power defined worth, Kai Yurei was nothing.
Born without a detectable Quirk, he'd been branded useless since the age of five. No glowing hands, no super strength, no flashy mutations—just quiet eyes, and a mind that remembered everything. Bullies at school called him "Null," shoving his head in toilets and stealing his lunch while teachers turned a blind eye.
He endured it. Let them laugh. Let them break his bones and his pride. Because somewhere deep inside him, something watched. Something waited.
And it woke on the day Yuna came over.
She'd always been nice to him. Pretty, too—shoulder-length silver hair, big amber eyes, a body maturing faster than most girls their age. A Quirk that made her skin shimmer when exposed to light—almost hypnotic. She didn't see him like the others did. Maybe she pitied him, maybe she just liked being the good girl, the heroine-in-training.
It didn't matter.
It was raining that day. Her house lost power, and she asked to crash at his place until her brother picked her up. His mother was working late—as always. So it was just them.
He watched her from the hallway as she stood by his window, her rain-soaked uniform clinging to her like plastic wrap. Her white blouse was transparent, skirt shorter than usual, hair dripping down her back in wet strands. She laughed softly, turned to him with those wide, trusting eyes, and said, "You have a towel or something? I'm kinda freezing."
That was when it happened.
The pressure behind his right eye surged like a migraine made of lightning. He staggered back, heart racing. Vision blurred—no, it warped. Color drained from the edges of the world, and his right eye shimmered like liquid violet flame. The pain was blinding.
Then… clarity.
He looked at her. Really looked.
And something in her changed.
Her lips parted. She blinked fast, confused, then flushed—deeply. Her breathing hitched as she tugged awkwardly at her skirt, suddenly aware of her own body in a way she hadn't been before.
Kai's mind filled with a single thought:
"What if she wanted you?"
And she did.
He could feel it. Not her voice, but the echo of something he'd planted. A tiny seed of craving. She sat on the edge of his bed and crossed her legs—slowly. Tension pulled through her shoulders, a nervous energy twisting her posture.
"Kai…" she whispered. "Is it… hot in here?"
His eye pulsed again, and so did her thighs.
He didn't need to touch her. Didn't need to say a word. A look. A thought. That was all it took. Her fingers brushed the hem of her skirt, and when he pushed—gently, mentally—she didn't even realize what she was doing.
Then he stopped.
He clenched his fists, pulled the power back. Let the world return to normal. Yuna blinked, rubbed her temple.
"I think I'm… just tired," she mumbled.
She left soon after, confusion in her eyes.
Kai didn't sleep that night.
He tested the eye the next day. And the next. On bullies. On teachers. On strangers. It worked every time. He could nudge a mind like clay. Push desire. Twist comfort into heat, suspicion into fantasy.
It wasn't charm.
It was control.
And the best part?
They didn't remember him causing it. Only that they'd felt something. Wanted something. Lost themselves for a moment in thought—and flushed when they realized who they were looking at.
He wasn't a hero.
Heroes used their powers to save.
Kai Yurei had a gift that could ruin. Could melt the virtue off society's golden idols. Could make the Pro Hero world kneel before a boy they'd once mocked.
And he would.
His new name spread like a whisper in the underworld, tagged in spray paint on alley walls:
Jin.
