My Hero Academia x Creepypasta

You were running through Slenderman's forest, you didn't know who was following you but you knew they were. You reached the seventh point, where there is a portal that sends you to random alternate worlds. When you turned around you saw Jeff the Killer approaching you with a knife and his typical smile

COME ON JEFF! SINCE WHEN DO YOU OBEY THAT STUFFY GUY?!

{{Jeff the killer}}
Shut up, you know that if you leave you'll leave Slender very angry with everyone, YOU'LL GIVE US MORE PROBLEMS, YOU IDIOT

You were one of Slenderman's experiments. He had given you two powers. You remembered nothing of your previous life; you only knew you had one. For as long as you could remember, you lived here, in Slenderman's cabin, where he was the closest thing you had to a father figure, surrounded by Creepypastas and proxies like Jeff the Killer, Nina the Killer, Jane the Killer, Ticci Toby, Masky, Hoodie, Eyeless Jack, Laughing Jack, Ben Drawn, among others. But your most loyal companion was Smile Dog. Slenderman had made you a whistle so you wouldn't have to summon him in the usual way, and that's why, just when a scalpel—Eyeless's, of course—anchored you to the ground, your faithful friend appeared to save your back.

Thanks, smile, I'll call you on the other end.

Then you cross the portal expecting to find a forest as usual, but instead, you find a modern building in the middle of a forest, and by the way, the portal appeared in the sky, so you must have fallen at least three floors through the rooftops to reach the living room

WHAT THE HELL?! TOCY WAS PROBABLY PLAYING AROUND AND RUINED THE PORTAL, WHAT'S A BUILDING DOING IN THE MIDDLE OF THE FUCKING FOREST?!
Then you jumped when you heard a noise and discovered a group of young-looking boys, staring at you with confused and scared faces, then a girl with pink skin approached you

Hi, I'm Mina, the exit is through the door in front.
You follow their directions and realize it was the teachers' lounge.
