Welcome to U.A!

It's been a week since the end of the U.A. entrance exam. Sirius knew very well that Izuku had already taken his place in Class 1-A, but didn't tell him about it to keep him on his toes. He collected the letter for Midoriya so that Izuku would not have to return to his father's place. It would turn very ugly very quickly. So he tossed the envelope like a grenade into Izuku's room and closed the door so he couldn't get out.

Sirius returned to the basement where Luna was waiting for him by the fireplace. The catgirl loved fire so much that she created a special set of Wards so that a fireplace could exist in the wall without the chimney.

She sat on a soft crimson sofa and kept her legs inside the fire. If it had been anyone else, Sirius would already be screaming bloody murder, but Luna was immune to fire so he had no reason to. Black fell onto the couch and laid his head on the girl's lap, not at all surprised when her hand began stroking his hair.

"Hmm, your hair is too heavy. What are you thinking?"

"Little things, big things, stupid things, but not smart things. For example, right now I'm thinking about how to get my students alive in their first class. Given what I did at their age, it will be difficult."

Luna hummed again and looked into the eyes of her beloved.

"You've done a lot of stupid things before. You hung out with Weasleys after all."

"Hey, Ron wasn't that bad."

"Ron was a man without much talent, so his mind was an easy target for the Wrackspurts. Tell me, now that your mind is clear of all influences, could you forgive Ron after he left you hunting Horcruxes alone with Hermione?"

Sirius fell silent. Would he forgive the man who betrayed him during the times of war? No. Would he be able to restrain himself and not rip his head off at the first meeting?

"Fuck."

"See? And I'm not talking about the fourth year yet. Friends do not abandon each other before a possible death. He abandoned you not once, but much more, so I do not think that your relationship with him was healthy."

Luna kissed Sirius' forehead and silence fell between them. They didn't often talk about the past, but when they did, it always ended like this.

". . . I miss them."

"I know. To see them smiling, talking to each other, running on the grass to the river next to our house. . ."

They fell silent again. Sirius knew perfectly well who Luna was talking about, but did not ask anything. None of them talked about their kids - who don't even exist in this timeline - it hurt too much.

"You know, sometimes I think how many animals I didn't manage to find? How many died before anyone could see them?"

"Far too many." He muttered.

". . . If you had the chance, would you come back?"

Sirius laughed.

"Oh, how I wish I could've come back. I want to see my friends, to see my two wonderful children, to live my own life again. To know that this timeline was swallowed by my death is agonizing. But there are people here who need me. People who love me." He looked at the beautiful silver feline eyes above him. "People who I love. . . This is my life now, has been for quite a while. My wishes can't change that."

Luna bent down and kissed his forehead without even removing her hands from his head. The catgirl hummed and lifted a lock of his hair as if weighing it.

"It's better, your hair is much lighter now."

"That's good."

They spent the rest of the evening talking quietly next to the fireplace, completely ignoring the joyous cries of the three children on the upper floor.

Izuku stood with Gin at the gate in the U.A. This time not as a visitor but as a student. Sirius had to leave earlier than usual, so the teenagers had to get there on their own. The trip was long, hot, and disgusting. Sometimes Izuku wished he had Black's coldness. Only sometimes.

"What do you think your classmates'll be like?" Gin asked suddenly.

Izuku thought for a moment and then answered.

"They'll be weird."

"What? Why?"

"Every Hero in the top 10 has a weird kink. All Might is All Might, Endeavor is angry as fuck all the time, Hawks is. . . relatively normal, but you get the idea. Anyone with a strong or advanced Quirk is just weird. We can only thank God that they are not like Sirius."

They entered together but got separated in one of the corridors. The first years occupied three floors in the building, the same amount as the rest. The first year of the Support Course was on the whole second floor so they wouldn't blow anyone else up during their experiments.

Midoriya walked to the huge door of Class 1-A and stopped as he heard the screams of his classmates. He knew those two loud voices, the first was definitely Bakugo, and the second was that guy with a stick in his ass.

"Just great, why was I expecting peace? Maybe I shouldn't go inside? I could study in another school. . . city. . . country. . ." He looked at the door with a conflicted face until he heard someone running down the corridor. Izuku turned and saw the girl he had helped during the exam.

Ochaco Uraraka was a short girl of a slender yet curvaceous figure. She was fair-skinned with a perpetual blush on her cheeks. Her eyes are large and round, their irises a warm auburn brown, with rather thick upper eyelashes. Shoulder-length and about the same color as her eyes, her hair is bobbed and curved inwards at the ends, two longer clumps taking the same shape on either side of her face, and short bangs that reach roughly a quarter of the way down her forehead.

Izuku thought she looked very cute in her school uniform. She wore a gray dress jacket with green stripes: the thin one below the tick one, two pockets and gold buttons, a white dress shirt, a red tie, a black pleated skirt, black tights, and brown slip-on shoes.

With his height of one hundred and seventy-five centimeters, he was almost a head taller than her, and if you take into account his curly emerald hair. . . It's easier to say that he looked taller than her. As soon as Uraraka noticed him, her eyes immediately shone.

"Oh, I knew that I would see you here! I didn't have time to thank you last time for saving me! I didn't think it was possible to bring a rocket launcher to the exam!"

"I made it on the spot, so it didn't get in the way of Support Gear Regulations." He answered with a smile, but she disappeared immediately when he heard voices from the class.

"Like I care. What middle school are you from, you extra?!"

Izuku's eye twitched in annoyance. He decided to become a Hero and nothing will stop him, even if he has to communicate with that bastard, he will follow his dream.

"Well, time to start our first day at U.A., huh?"

"Yes! We've got our entrance ceremony and guidance lessons today, yeah? Wonder what our teacher'll be like. Boy, I'm nervous."

Izuku's face suddenly looked like he had eaten a lemon.

"Sirius laughed far too long when he talked about my entering 1-A. So if you're nervous, then you have a reason."

"Huh? Who's Sirius?"

Izuku was about to answer when someone from behind spoke up.

"A thorn in the side that is impossible to get rid of."

Behind the two teenagers, none other than Shota Aizawa was lying on the floor. There was a bag of juice in his mouth, and there was endless tiredness in his eyes. He was in a yellow sleeping bag with strange symbols on it. Izuku recognized them as runes but said nothing. Most likely it was a gift from Sirius on some important date.

"Now go to class, the bell will ring in twenty-three seconds."

The man looked too much like Sirius for Izuku's tastes. All the same long hair and the same stubble on the face. But Aizawa was taller than Sirius. And much more tired.

Ochako and Izuku entered the classroom and took their places. Kirishima and Mina waved to their friend and he waved back. The green-haired teenager tried to ignore the way half of the class stared at him, the other half stared at Uraraka. The looks were expected, they were the last to come in after all.

Nobody had time to say anything before the bell rang. The door to their classroom immediately flew open and Aizawa crept inside unnoticed. His shabby figure stood at the teacher's table and he just glared at his students. Gradually, the conversations ended and everyone was able to focus on the strange person in the class.

"Seventeen seconds. You wasted seventeen seconds of precious time on useless conversations. You lot aren't very rational, are you? I'm your Homeroom teacher, Shota Aizawa. Pleased to meet you."

The yellow sleeping bag landed on the floor behind the table and Shota stretched his stiff shoulder.

"Change into your gym clothes and head out to the grounds. Whoever is late will be handed over to Helga as late breakfast."

"Helga's here?" Izuku muttered and frowned even more.

No one heard him mumbling, everyone was in too much of a hurry to the locker rooms.

Already in the locker room, Izuku took off his school uniform and began to put on his gym clothes when he was stopped by a sharp breath from behind.

"What are these tattoos?! Dude, that's so cool!" Said a couple with strange holes on his elbows.

"Tattoos?! Students are not allowed to have tattoos on their bodies until they come of age!" The bespectacled man with a stick in his ass waved his arms like a robot.

Bakugou angrily huffed and slammed the door out of the locker room. Izuku put on his clothes and rolled his sleeves up to the elbow to keep them out of the way. The shape was a little small for him and accentuated his muscles too much, but he could handle it.

"It's a necessity to control my powers. Without them, I would have to draw circles every time I want to do this."

Midoriya touched his bracelets - which he had removed to change his clothes - and they turned into steel gloves on his hands. The blue lightning slowly faded from the ETC and Izuku held up his hands for everyone to see the result. The guy with the glasses looked thoughtfully at his hands and hummed.

"I see. . ." He bowed sharply at ninety degrees, slightly shocking Izuku. "I apologize for my hasty conclusions! This was too low for a future hero!"

"Lord, calm down, no one asked you to apologize. Just pull out this stick that is stuck in your starter and chill. You'll need it today. . ."

Sirius sat on a high stone throne on the grounds next to the U.A. building. He was dressed in his "Hero" suit and held in his right hand an Elder Wand, enlarged to the size of a staff - who knew that it could turn into a staff? Rowena and Helga crawled around him, but the rest of the Basilisks decided to stay in their places. Moonbean lay on his lap, purring in satisfaction from the pats on the head.

Next to him was the same throne for Aizawa who had just come to the field. The tired Hero just looked at the empty throne and sighed heavily.

"What the hell are you doing?"

"What? Can't I scare my students?"

"Drama Queen." He muttered as he fell onto the throne.

Pretty soon all the students came to the grounds and could only look at the horror that awaited them. Two huge, almost identical snakes slithered around two thrones in the form of an infinity symbol. Two almost identical men sat on these lofty thrones and looked at them like dirt under their feet.

The first one was Aizawa Shota whom they had already seen, and the second was Sirius Black. His black clothes were a strong contrast to the red coat on his shoulders. White gloves with strange symbols on his hands distracted attention from the silver cat in his lap.

Izuku's eye twitched again. He had to squeeze Kirishima's shoulder, who immediately hardened his arm. Sirius heard a soft crunch anyway.

"Greetings, my disciples!" Black dramatically spread his arms to the sides but did not rise from the throne. "As you can see, I cannot welcome you on my feet. My cat's sleep is more important than my manners. But let's not waste time talking, you have bigger problems right now. It's time to test your Quirks!"

Basilisks hissed approvingly around him, forcing the students to step back. Only Izuku stood in his place and groaned into his hands. He knew something like this would happen, why did he want everything to be normal?

"A test of our Quirks?!" The students finally realized what he had said.

"What about the entrance ceremony!? Or guidance sessions?!"

"That's the stuff for students, you're not students yet." Sirius said with a cruel smile.

Everyone's faces turned white at his words. And then the chaos began.

"What?! But we passed the entrance exam!"

"If this is a joke, then it is unacceptable for the prestigious School of Heroes!"

"How can I get all the girls if they kick me out?!"

"What the heck?!"

Sirius raised his hand and hit the ground with his staff, sending out a shock of sparks and silencing everyone. Now he understood why Snape had always been so annoyed, children can be a real pain in the ass.

"This gentleman will explain everything now." So he gave this pain to someone else.

Aizawa rose from his throne and began to slowly descend the stone steps.

"Softball trowing, the standing long jump, the 50-meter dash, endurance running, grip strength, side-to-side stepping, upper body training, seated toe touch. You did this all in middle school, right? Your standard no-Quirks-allowed gym tests."

He stopped in front of the Basilisks and they opened the passage for him.

"This country still insists on prohibiting Quirks when calculating the averages of those records. It's not rational."

"They do it to keep people like me from showing up."

Aizawa glared at Sirius who raised his hands in a sign of peace.

"Partly. . ." The tired Hero admitted. "But the Department of Education is just procrastinating anyway."

He took the ball out of his scarf and threw it towards Midoriya, who instinctively caught it and looked at the teacher with a mute question.

"Midoriya, how far did you throw in high school?"

"Sixty meters. They simply were not allowed to throw further, the greedy bastards did not want to lose their priceless balls." Izuku rolled his eyes, his joke made a couple of people blush, but no one dared to laugh.

"I'm not going to comment on this. Now throw it up with your Quirk. Do whatever you need to do, just stay within the circle."

Aizawa knew full well that Izuku didn't have a quirk, but everyone else was still in the dark about it. The sooner they know about this technicality the better.

Midoriya tossed the ball into the air a couple of times, weighing it in his hand.

"Sensei, there is only one small problem."

When the ball was in the air again, Izuku's silhouette blinked and in a second was next to the ball. An emerald aura flowed from the legs of the green-haired teenager, and before anyone could blink again, he had already sent the ball into the horizon with a strong kick. The ball flew forward, breaking the sound barrier.

"This aura..." Ojiro muttered.

Izuku landed on the ground and shook the nonexistent dust off his shoulder.

"I'm Quirkless."

Sirius would have applauded Izuku, but he didn't want to show bias from day one. So he just quietly enjoyed the atmosphere.

"It is important for you to know your limits. This is the first rational step towards understanding what kind of Hero you will become."

Aizawa just looked at his phone, which was measuring the distance of the ball and his eye twitched, he expected something like this. He turned the phone around to show it to everyone else.

"1337 meters exactly."

Izuku had a smug grin on his face. If Sirius has already turned the test into his personal theater, why can't he perform?

His classmates' jaws hit the floor at his statement, but the most shocked was Bakugo. The useless freak does THIS and dares to claim that he's Quirkless?! He would accept the "late bloomer" explanation, but that crap? Never.

So he decided to do what he always does.

"Deku. I'll fucking kill you."

Find out the truth by force.
