A Smile With Claws || Katsuki Bakugo

Kimiyo Kamiyana has always known how to disappear.

With a smile as bright as sunlight and a laugh that draws people in, she is everything Class 1-A adores, kind, bubbly, endlessly warm. A girl who makes everyone feel seen. A girl who never cries. A girl who always puts others first.

But behind the glow is a Quirk built on illusion, invisibility, and escape. And behind the smile is a childhood shaped by ruthless training, a cold home, and a mother who demands perfection at any cost. Kimiyo learned early that being loved meant being useful, and that the safest place to hide was in plain sight.

At U.A. High, she shines brighter than ever. She is the class's sunshine, the glue holding friendships together, the quiet comfort others lean on without realizing how much weight she carries. Katsuki Bakugo sees it all, the cracks beneath the cheer, the exhaustion she masks, the way she vanishes when things hurt too much. He's been in love with her for as long as he can remember, and she's been holding his fire just as long.

Everyone can see what they are to each other. No one sees what Kimiyo is becoming.

As danger grows and the line between hero and sacrifice begins to blur, Kimiyo must confront a truth she's spent her life avoiding: disappearing may keep others safe, but it will destroy her. And if she wants to survive, she'll have to stop smiling long enough to bare her claws.

Because even the brightest smiles can hide their teeth.
