Ryukyu, Izuku and Eri emerged from the office of Principal Nezu of UA. They had been in a meeting to determine the fate of the two siblings. The main issue they faced was the bond between the two. They trusted no-one but each other. Some heroes they were willing to interact with, such as Eraser and Ryukyu, but they mostly kept to themselves. Whenever someone got too close, Izuku's horn would glow dimmly as he non-verbally threatened whoever it was, whilst holding his sister close to him. It was understandable, but complicated certain things. They would be unable to seperate the two, that was painfully clear, so they had to find a way to involve both of them in everything. Eri was unwilling to be without her brother anytime soon, and Izuku would not let Eri be taken somewhere that he wasn't. The years that they spent in the hands of the Yakuza had caused them to become completely inseperable. It was not an unusual thing. A tortured, protective older brother defending his younger sister from anything and everything. Not even All Might would be able to take them away from each other. The 5 year old girl would cling to her brother at all times, and the teen would kill to protect his sister.
It was determined that Ryuko would take care of them most of the time. But, when she was needed elsewhere, they would be watched over by Aizawa. The siblings agreed to this, Shota Aizawa and Ryuko Tatsuma were the two people they trusted the most, aside from each other. But then came possibly the hardest part. Introducing them to the classes that Aizawa taught. He was a teacher by day, hero by night. And so, Izuku and Eri needed to be familiar with the students. The third years would likely be no issue. The duo already knew the big three, and the most challenging part of the third years would have been Nejire's questions. But that was not a problem this time, What Aizawa was most worried about was his first years. 1A was a handful, and he was concerned about how siblings would react. They already knew 3 of them, Uraraka, Tsuyu and Kirishima, but not the rest. Certain pupils, such as Momo Yaoyorozu, Shoto Todoroki and Kyoka Jiro would be easy enough. However people such as Mina Ashido, Minoru Mineta, Katsuki Bakugo, and Fumikage Tokoyami would be harder. Mina for her excitable and playful personality, it could be a bit overwhelming. Bakugo's anger issues and explosive nature. It would not be a surprise if Mineta said something that made Izuku beat him into the ground. And lastly, Fumikage Tokoyami was not a bad person. However, his birdlike appearance may provide traumatic flashbacks for the siblings. The Yakuza liked to wear mask resembling large birds.
"Settle down and listen up," Aizawa stood in front of hero course class 1A. "There are two people you need to meet. A few of you already know them, but I shall warn you all now. Both have lived through hell, so be calm when they are around. Don't spook them or act badly in their presence. They are siblings and the older one is fully prepared to kill anyone who he deems a threat to himself or his sister. And Tokoyami, their captors wore bird masks, so they might be wary of you." The boy nods in understanding. "Wait here while I get them."
Once Aizawa left, the class began talking. After a small amount of time, Aizawa returned. Behind him came Ryukyu, followed by a silver haired teen with a horn on the side of his forehead, and a young girl ,with similar hair and horn, in his arms.
"These two are Izuku and Eri. We don't know their last name. Feel free to ask questions but don't be surprised if they don't answer."
A few people decided to shout questions immediately. The sibling duo recoiled, before Izuku's horn flashed and they were gone.
"I TOLD YOU TO BE CALM AND NOT SPOOK THEM! THE FIRST THING YOU DO IS YELL QUESTIONS AT THEM? HOW STUPID CAN YOU BE?!" Aizawa calmed himself before turning to Ryukyu. "Could you try to get them back in? I'll deal with this lot."
Ryuku nodded, heading to the door. She emerged into the corridor and began looking. She found them huddled in a corner, Eri crying into her brother's shoulder. Izuku was doing his best to comfort her.
"Hey, you two. You alright?
Izuku looked up at Ryukyu, before looking back at Eri.
"Look, I'm sorry about them. Aizawa told them to be calm but clearly some didn't listen. He's making sure they won't do that again."
Once more, Izuku looked up at Ryuko, and then returned his attention to Eri. Standing up, he walked over to his and Eri's new mother, Eri still in his arms, and signalled for her to take them back to the room. She smiled and did just that. They re-entered the room, and all eyes turned to them.
"Now that they're here, you can ask some questions, get to know them and introduce yourselves. Quieter this time."
Hands were raised into the air. Aizawa picked out a pink skinned girl.
"Why is Ryukyu here as well?"
"I'm going to be their mother. We're just waiting for it to be certified."
The girl nods. Aizawa scans the room, before selecting a girl with long black hair, tied into a ponytail.
"What are your quirks?"
The boy looks to Aizawa, as if to get confirmation that they could trust the class. No-one who knew there quirks had treated them well, only Aizawa and Ryuko. Aizawa provided the reassurance.
"Mine is called Standstill. Hers is Rewind."
"What do they do?"
"She can rewind the state of any living thing. I can stop time." Murmurs fly around the room at the announcement. Aizawa selects a boy with a tail.
"How old are you?"
"I'm 16, she's 5." This response recieves a large number of gasps and shocked faces. Even the boy who remained stoic the whole time showed a reaction. Next was a boy with grapes for hair.
"Aizawa-sensei said that you would kill us, is that true?"
"If I deem you a threat to me or my sister, then without hesitation." Izuku's horn glowed as if to highlight his point. Next was a yellow haired boy.
"Why does your horn glow?"
"It's a signal that my quirk is active, or about to activate. Eri's glows whilst hers is active too."
"Why do you have them? Your quirks aren't mutations."
"We don't know. All I remember is that they are completely unique to us two."
The boy nodded, satisfied with the answers. Aizawa once again scanned the room, picking a boy with a limb mutation.
"Are you going to be in this class?"
"I-I don't know. Eri and I haven't been told."
"Not yet, they won't" Aizawa provided an answer. "After a while, maybe. But currently they'll be in and around the school, but not a member of any classes. They will, however, be staying in the dorms. Specifically the teachers' dorms." Whispers flew around the class. Eri squirmed a bit, burying her head into the crook of Izuku's neck. Izuku kissed the top of her head, uttering comforting words into her ear.
"It's OK, Eri. I'm here. I've got you, always will. I'll protect you, little sis. Don't worry."
Eri began to relax. With her head still pressed against his neck, she tightened her grip on her brother. She rested against his shoulder, gradually falling asleep. Once the silver haired girl was safely sound asleep, her brother looked back at the now silent class, an intense glare plastered on his face.
"Be quiet. Do you not listen to your trainer."
"Trainer? What are you on about?"
Izuku faltered a bit. "Eraserhead. Your trainer. Is that not what he is?"
"No he's our teacher. Have you never had a teacher?"
Izuku stepped back, his breathing beginning to increase. His eyes darted around the room, never staying in the same position. His horn flashed, and he and Eri disappeared. Aizawa and Ryuko bolted out of the room. They found the duo back in the same corner as before.
"I-I cant do it anymore, Mr Aizawa. It's too much. I don't know what's real anymore."
"It's alright, kid. Calm down. They're just concerned, they don't know the full story. There are a lot of things that you'll need to re-adjust to. Don't worry though, we'll help you. Come on, we'll take you to the dorm room you'll be sharing."
Izuku closed his eyes, and took a few deep breaths. Upon opening his eyes, he saw Eri looking up at him. He smiled at her, and she snuggled into his chest. Izuku stood up, nodding at Aizawa and Ryuko. The dragoon hero approached them, taking Izuku by the hand and lead him and Eri to their new home.
