Quick Monster!Katsuki AU with Human!Izuku
Kats is a monster that lives under the bed and he’s been stalking Izuku’s ankles for a while now. Ever since the nerd moved into the house Katsuki has been waiting for his moment. He watches Izuku and learns his habits and personality.
One night weeks in Izuku’s ankle and foot hang off the side of the bed and Kats spooks him a little by grabbing it but not pulling Izuku under just yet.
Izuku is FREAKED out of course by the feeling of a cold clawed hand wrapping around his ankle and tugging and makes sure to keep his feet on his bed and tucked in every night. Which amuses and annoys katsuki who is biding his time. Katsuki sometimes does spooky stuff like scratch on the bottom of the bed frame or let his shadow cross the corner of izukus eye sight. Always reminding the nerd he’s waiting and watching. Never far from his prey.
Izuku, skittish and scared, starts trying to communicate but katsuki isn’t stupid so he doesn’t ever answer on the recording devices or whenever a camera is rolling. Over time Izuku gets used to having a haunted home but is always on the look out for the next scares his uninvited roommate has for him. At some point though, Izuku finds a little comfort that he’s not alone when he gets home. Strange as it is.
Almost a year in one night Izuku comes in rather dejected and upset. The nerd has been acting a little off for about a week. That night Izuku’s leg hangs over the edge of his bed ripe for the pulling, but as Katsuki goes to grab his ankle he hesitates. He’s enjoyed his time stalking his prey…enjoys his prey in a lot of ways actually. He doesn’t want to just…eat Izuku like he normally might any other prey. No, Katsuki wants to play with Izuku. Wants to hang around as the nerd does his nerdy things. Listen to him ramble on to himself about his little theories and ideas. Wants to make sure he remembers to fucking eat by knocking shit around in the Kitchen or for him go the hell to bed when Kats starts rattling things in the bedroom/tossing pillows at Izukus head. Katsuki just…wants him.
So as he pulls his clawed hand back he contemplates what he should do. The next night it’s the same. A dejected Izuku goes to bed and eventually his leg hangs over the edge of the mattress exposed. Almost like he forgot Katsuki exists.
It’s annoying and hurts Kats pride but he doesn’t want to HURT Izuku. So he’s kinda stuck.
3 days of this go by before one night Izuku, leg hanging over the mattress, sighs a frustrated groan into the quiet bedroom. Katsuki frowns as Izuku huffs to himself before addressing Katsuki himself. “So NOW you grow quiet? Really? After all this time?”
Stunned Katsuki shifts under the bed in his shadows and listens as Izuku sits up angrily and then leans over the side of the bed to stare into the darkness. While he can’t see Katsuki it still makes him flinch a little as those pretty but sad jeweled eyes peer angrily all around as though he’s looking for Katsuki.
“Seriously? I’ve been dangling my ankle outside my blankets for days and you won’t bite? Of course not. Not when I ACTUALLY want you to. Figures, the minute I DONT want to be here anymore you decide I’m not worth it. Come on, just take me now. You’ve been actively haunting me for almost a year every night. Why are you being a coward all of a sudden?”
And doesn’t that just peak Kats interest. The little nerd doesn’t want to live his sad little lonely human life so he wants Katsuki to eat him? Well well well….he can do that. Just not the way Izuku expects.
He chuckles darkly just for Izuku to hear. Green eyes widen as Katsuki allows his wide grin full of sharp teeth to pierce the darkness. As Izuku sees that terrifying grin the nerd sucks in a frightened breath and before he can back up Katsuki reaches out and grabs him, pulling a screaming Izuku into the dark shadows. “Be careful what you wish for I-ZU-KU.”
When Izuku shows up to work a few days later people are surprised to see a wide grin on his face. Especially since he’d recently gotten in trouble for something he didn’t even do but no one wanted to get themselves caught into the mix so they let him take the fall. Izuku is practically glowing and as the day moves on he gets more and more animated the closer it gets to the end of the shift. When asked he just smiles and says he has a special someone waiting at home just for him and he can’t wait to rush home to them.
Izuku is congratulated and as he makes his way home and steps into the entry way he grins as an obvious shadow slithers impatiently down the dark hallway. “I’m home Kacchan!” He laughs happily as he’s then yanked into the darkness by familiar clawed hands.
AN: just an idea I had but didn’t want to make a full fic because I don’t have a working brain cell right now.
