Universes calling (a former FNF MHA crossover. This book is now mine.)

UA

Aizawa's POV: it was hard to focus it was an exhausting day. First Midoriya breaking his bones again and having to go to recovery girl. Then Bakugo started a fight with Lida again and nearly blew up the gym. And then Mineta was caught snooping around the locker rooms we had to suspend him for a while.

He was startled out of his thoughts by a large portal forming at the top of the classroom cracklings with dark energy.

Everyone stopped what they were doing and looked up in fear.

"Stand back!" I shouted "they might be villains!" Then suddenly two kids fell through.

Both appeared to have a black substance covering them but one appeared to only have it half covered, both were clenching their heads in pain.

"Urakura!" I shouted to the brown haired girl. "Go get recovery girl these kids need medical attention now."

"What is this stuff?" Momo said.

Aizawa stopped her before she could touch it. "Don't touch it, it might be a part of their quirks."

They stopped their conversation to see the orange haired boy slowly open his eyes. One was a bright pink while the other was green.

Mina's eyes widened in shock. "Hey are you alright that is a pretty bad head wound you have."

Aizawa looked closer then reeled back only now noticing the chains around his waist.

"What's your name?" Momo asked.

"M-my names Pico." Pico replied, "and my friend over there is Kieth."

"What's your quirk?" Aizawa asked calming down, "is it that black stuff on you?"

"Black stuff? Wait we're still partially corrupted but I feel in control." Pico shouted out loud.

"In control?" Aizawa asked.

"Oops, wait!? Did I say that out loud!" Pico yelled, "well I guess I'll have to explain this now."

——— after explaining ———

Wait so they were corrupted by some kind of demon! Aizawa thought unaware that someone was listening in.

Toga's POV: ohhhhh Shiggy's going to be interested in this information. Maybe we'll even gain a powerful recruit. I'll see if Kurogiri could make a portal to this dimension they speak of. I thought with excitement.
