After a short stay in the hospital, Izuku was called to the Hosu police station to clarify the facts. When he arrived, he was received by the police chief, who had the head as that of a dog and a human body; the vampire was sure that if Alucard ever saw him he would a serious existential crisis.
"Well, Mr. Midoriya, as you know, it's forbidden to use quirks without a hero's license," said the cop, sitting behind a desk.
"Yep," answered Izuku, standing on his feet.
"This is what we will do, we'll say it was Endeavor and Hellboy the ones who defeated Stain and you just were passing by, woof."
"And if I want to take credit?" he asked already knowing the answer.
"You would be accused of using a quirk without permission, woof. Which would make a big stain on your registry."
"Mister," he read the plaque with his name, "... Tsuragamae, I have no quirk, and that's why I want to take the credit I deserve."
The cop was speechless, how was possible someone without a quirk could defeat someone like the hero killer?
"You lie," said the man-dog, thinking it was false, "those injuries couldn't have been made by someone without a quirk."
"Bring a doctor and I will show you it's true."
Tsuragamae immediately called for a quirk specialist and went to the Hosu hospital. The doctor took blood samples, x-rays, a tomography, etc; to check if he actually didn't have a quirk. While waiting for the tests' results, Izuku went to visit Tenya.
"Tenya," said the vampire after teleporting inside the room.
"Izuku!" shouted the blue haired teen, resting on the bed with an arm and a leg in a cast. "I almost had a heart attack, don't do that again," he added more calmed.
"Alright," he said, bored, "I won't do it again. You are no fun.
"What are you doing here?"
"I came to visit your sad and miserable existence."
"Ehm... thanks, I guess."
"How do you feel after almost dying for your stupidity?"
"Like the biggest fool ever."
"And...?"
"I'm sorry, I'm sorry for being so selfish and unheroic," said Iida with his head down.
"Alright, I forgive you for this whole thing."
"What?! Just like that?! You almost died too for my fault!" he shouted doing his strange gestures.
"Yes, just like that, and I was never in danger, I'm already dead."
"Explain yourself, Izuku."
"If I tell you, do you promise not to do anything like this again and that you'll trust in us? Also, you can't tell anyone else what I'm about to tell you."
"Okay, I promise."
"Well, I don't have a quirk; I'm actually a vampire."
"..."
"..."
"I suspected it; the whole class suspects it."
"Is it so obvious?"
"My friend, you drink blood, nobody has ever seen you eat anything and Dark Shadow fears you, according to Tokoyami."
"Ok, aren't they scared of me?"
"A little when you fake being dead and then reform your body," the boy answered, scratching his head.
"Ah yes, the ol' reliable," said Izuku. "Well, my results must be ready," he started to phase through the floor, "I'll see you in class, byyye."
Izuku arrived in shadows at the doctor's office.
"Did I miss something?" he said suddenly, with his head out of the portal.
"Holy shit!" shouted Tsuragamae when he saw him.
"Easy there," said Izuku and finished going through the portal. "And... according to the tests, I have no quirk, right?"
"Right," said the doctor, "but here I am, watching you coming out of a portal. These tests are infallible, what are you?" he asked with curiosity.
"Answer, Mr. Midoriya."
"I'm a vampire, of a very special species by the way," he made a pause. "So, can I take the credit?" he smiled.
After explaining that All Might and U.A know about him and the school had taken the required measures about his diet and that he isn't a danger, Tsuragame accepted reluctantly to give him the credit and they told he did it without using his quirk.
When he was back to school, everyone except his class looked at him with either fear or respect.
"Midoriya, you're on detention," said Aizawa, just after he stepped in the class.
"Now why, momma caterpillar?" asked Izuku, with a Cheshire's cat like shit eating grin.
"Don't call me that. For being a sly bastard that uses legal lagoons. In a moment I'll tell you your punishment," he looked to the other students. "Kids, we'll be doing an activity, after finishing the final exams, we're going on a camp trip for the weekend."
The class exploded with joy.
"Shut up, the only ones going are the ones who pass their final exams. Izuku, your punishment will be to clean the bus will use with dental floss."
"NOOOOOOOO!" yelled everyone except Izuku, who blocked out his ears and didn't give a fuck about his punishment.
After classes, Momo offered to help study her classmates and Izuku revealed to be a vampire.
After the revealing, his classmates asked him a lot of things, like teleport them to the grounds or the cafeteria. One day, Mineta and Denki asked him to teleport them to the girls' changing rooms, but Izuku teleported them to the Sahara, after a few minutes he picked them up and warned them if they asked him that again, he was going to teleport them to Tibet or the ocean's bottom.
When exams arrived, everyone passed the writing part of it. Then, next day, they made the practical part, which consisted of them fighting in pairs against a teacher. If they beat him, put on him cuffs, or one of them escaped they would pass the test.
The students would fight All Might, Nezu, Eraserhead, Midnight and other heroes. Due to Izuku's skills, he was forbidden to use familiars or the sexual beam and he teamed up with Katsuki.
After a few minutes, the vampire's and Katsuki's turn came and they were surprised to see they would fight All Might.
"Young Midoriya and young Bakugou," greeted the hero with his permanent smile, "now I'm a villain and you will fight me as such," now his smile gave them chills. "Don't worry, I'm using weights that hold back my power to half," he pointed at some kind of bracelets he was wearing. "So, let's start, shall we?"
Then All Might, basically disappeared due to the speed he was moving at, surprising Katsuki, Izuku saw him at a normal speed and dodged him. The hero threw Katsuki pretty far away, the kid could just barely get up.
"Shitty nerd!" shouted Katsuki. "You better have a plan!"
"Oh yeah, I do," Izuku said mysteriously after appearing behind the explosive boy. "I have plenty of options, what will you choose? Leave him unconscious? Run away? Hurting him so much we can put the cuffs on him? Make him give up?"
"You are scaring me?" said Bakugou. "I think I choose to leave him unconscious."
"Alrighty," he was going for All Might but he was stopped by Katsuki.
"Hey, just a quick question. Why you didn't eat that weird thing the villains had?"
"That piece of crap didn't have a soul, I can't absorb it if it doesn't have a soul. But I already took care of it, I ripped off its head, and destroyed its brain and body, and sent the head in a gift box to the villains in a portal.
"..."
"..."
"I shouldn't have asked."
"Hey," said all Might behind them, "don't ignore me," he gave a powerful punch, but Izuku made himself intangible, while Katsuki barely dodged it.
"Excellent," said the vampire while opening a portal, "you saved me the job to go for you."
Izuku put the portal below All Might.
"Omae wa mou shindeiru," said Izuku and made the hero fall through it. After 10 minutes, the vampire made an opening and All Might hit the ground with tremendous force.
"Hey, he's pretty weakened, but isn't unconscious," said Katsuki while approaching the hero.
"I thought it wasn't fair I won alone," he pointed at All Might and smiled. "All yours, Kacchan."
After a few minutes, in which the weakened Peace Symbol still fought Katsuki, the latter ended up putting the cuffs on him and they won.
Meanwhile, at the League of Villains bar, Shigaraki looked annoyed and bored at the new recruits that thanks to their "association" with Stain and an old contact, decided to be villains.
"A burned boy and a crazy girl," said the villain, inexpressive. "You," he pointed at the blonde girl with an eternal blush and with her hair tied in two messy buns who also wore a schoolgirl outfit. "What's your name?"
"I'm Toga, Himiko Toga. And I worship Stain, I want to be like him, I want to kill him and-"
"Tomura Shigaraki," called Kurogiri, "I apologize for the interruption, Himiko Toga, but this is important," he apologized and looked at Tomura. "This arrived through one of my portals," he pulled out a red gift box with a green ribbon."
"Kurogiri, we're not in Christmas, get rid of it."
"No, it's not that, the important thing is who is it from."
"And who is it from?"
"The note says 'From Nosferatu to Handy'"
"That son of a bitch," growled Shigaraki.
"Who are you talking about, Mr. Shigaraki?" asked Himiko, the other boy also was interested.
"About a being more powerful than All Might and the one who defeated Stain," replied the villain of the hands.
"Izuku Midoriya?" asked the burnt recruit.
"That one... ehm..." said Kurogiri.
"Dabi."
"Midoriya? Is he son of Hisashi Midoriya?" asked Himiko.
"Yes, he is the son of the rooky villain that disappeared last year along with other who we know were devoured by Izuku," said the mist man.
"That motherfucker dared to humiliate me and give a nickname," said Tomura. "Kurogiri, open up the box and let's forget about this thing."
The mist man opened the box and dropped it from the shock. Inside was the brainless head of the nomu, with a smile carved by knife along a note.
"What's that?" asked the blonde, surprised.
"That was a being designed to kill All Might," answered Shigaraki while taking the note careful not to disintegrate it.
After reading, he growled and sat at the bar.
"That son of a bitch we'll see, soon he'll have a surprise for him," said Tomura and asked Kurogiri a drink.
Dabi picked up the note and read it aloud.
"Dear substitute chief:
If you keep fucking with us Handy, I'll shove all your hands up your ass and then I'll push them until they go out your mouth.
Nosferatu.
PS: Alucard says jellouda to your boss.
PS 2: Whoever reads this is a fag."
After hearing the last sentence, Himiko cracked up laughing while Dabi angrily burned the note.
"That boy is interesting," said the blonde after calming down. "Wish I met him."
