The world was weird. Besides Quirks existing, everyone had a monster of their own. If it was a tiny troll, if it was a monster in a closet, even a shadow in a corner, they existed. Everyone had one. Even Izuku.

You were his monster. The monster under his bed. Ever since he was 4 he's had you. He'd always tell his mom 'There's a monster under my bed!' but she'd just say 'Of course. Everyone has a monster.'

And that's how he found out about you.

Everytime it was dark inside his dorm, you'd appear under his bed. You didn't look like a monster tho, just a few black marks on your face to signify you're a monster. Yet, Izuku grew used to seeing you. You'd always peek from under his bed when he'd be too close to the edge of his bed. You've been more like a friend to him. Even if it was creepy how you ALWAYS stayed under the bed. You never crawled out from under it, never got out to eat or use the bathroom. Well, that's what he was assuming. He didn't know what you'd do behind his back.

That's why he was so chill right now. He was in his dorm, sitting at the edge of his bed as he wiggled his feet. Why? Because he was just playing with you. "..Come onnn.... My feet are tasty.." He joked as he smiled. He saw your hand reach out for his ankle, and he pulled his feet up onto the bed quickly. "Too slow!!" He said.
