The rest of the day was normal. Too normal.
Katzo played blocks with Katsuki. Ate dinner (Mitsuki's curry, extra spicy). Took a bath. Brushed his teeth.
All while the words QUIRK MUTATED echoed in his head.
But nothing happened. No new sensation, no visible change. He went to bed disappointed.
Then he woke up in the middle of the night.
Not from a nightmare — just… awake. And aware of something different.
He sniffed the air. His room smelled like nothing. Not the usual mix of laundry detergent and his own kid-sweat. Just nothing.
He lifted his arm. Sniffed his armpit.
Nothing. No smell at all.
"Okay," he whispered to the dark. "Weird."
He padded to the bathroom, climbed onto the step stool, and stared at himself in the mirror. Same messy hair. Same four-year-old face. But his skin looked… cleaner? Like he'd just stepped out of a shower, even though he hadn't.
He touched his own cheek. A thin, clear liquid beaded on his fingertip — not sweat, not oily. Just… wet.
He wiped it on the sink. The porcelain seemed to gleam where the liquid touched.
It cleans things?
He licked his finger without thinking. Tasteless.
Then he noticed something else. His breath. Usually, morning breath was gross — even at four, he knew that. But now? Nothing. Just clean.
His mind raced back to the HUD's mutation notice. Mitsuki's Glycerin kept skin soft and glossy. His version…
It eats germs. It keeps me clean.
He grinned in the mirror. It wasn't an explosion. It wasn't flashy. But he'd never stink. Never have bad breath. Never get a dirty scrape that festered.
Not bad for a first roll.
He climbed back into bed, pulled the blanket up to his chin, and stared at the ceiling.
The HUD was quiet. No countdown. No new window.
But he knew it would come back. And next time, he'd be ready.
Next time, I'm copying someone with a combat Quirk.
He closed his eyes, smelling like absolutely nothing, and fell asleep smiling.
