__________________________________________________________________________________________________________

(Y/n):Well, here it is....

(Y/n) said to the White haired and Red eyed six-year-old girl who was holding his right hand.

(Y/n):Your new home!

It had been four weeks since Eri's rescue from the Eight Precepts of Death.

After all the heroes had recovered from the battle, the big question that came up among the teachers was what to do with Eri. After about an hour of thorough deliberation, everyone agreed that she should stay at Kurosu World High Academy in order to keep her safe from any possible future attacks. However, this posed another question: Where should she stay? Many teachers offered to let her stay with them; even Mirio offered to let her stay with him and the other Big Three members. However, during her time in the infirmary, the Headmasters noticed that Eri was the most calm and happy whenever The toddler Teen came to visit her. He then decided that for the time being, Eri would live with Class 1-A and (Y/n) acting as her temporary guardian.

(Y/n) felt a mix of emotions: happiness that he could help Eri and fear of the responsibility that came with it. He had always been a Goofball but now?He was the legal guardian of someone Who's TECHNICALLY older than him since she's 6 and he's actually 4 And how Kai Chisaki/Overhaul hurt her for his plan to create the Power-Destroying Bullets.

Eri looked around the 1-A dorms with wide eyes, taking in the unfamiliar surroundings. The bright colors of the furniture and the posters of various heroes on the walls were starkly different from the dullness of her old life. She clung to (Y/n)'s hand tightly, finding comfort in his warm, reassuring presence. He had promised to take care of her, and she had no doubt that he would keep his word.

As the soon as she entered the building, the first thing she saw was a kitchen. There was a refrigerator, a stove, a sink, a microwave, and other appliances that she knew existed, but had never used before herself. Sitting around a table almost as long as the room itself was a group of people around the same age as Midoriya. Some looked like ordinary people while others had certain features that made them stand out from the others. As soon as they saw her and Midoriya, they all rose from their chairs, standing awkwardly for a second.

Suddenly, a girl with pink hair and pink skin rushed forward toward Eri, bending a bit to Eri's height and with a huge smile on her face.

Mina:Well, aren't you just the cutest thing!

She exclaimed but This sudden move scared Eri and she hid behind (Y/n) legs and sobbed softly into them.

Toru:Mina!

she peeked an eye around the fabric in her hands to realize this was coming from a floating set of clothes.

Toru:You scared her!

Eri buried her face deeper into (Y/n)'s legs as he held her close as Byakuya Togami sighed.

Byakuya:Your BOTH Scaring her.

Mina looked shocked and took a step back.

Mina:I'm sorry! I didn't mean to!

Eri's sobs grew quieter but didn't stop. The other students looked at each other nervously, not knowing what to do next. (Y/n) knelt down and gently picked her up, cradling her in his arms.

(Y/n):It's okay, Eri. They're just happy to meet you. They won't hurt you, I promise.

Eri clung to him, her tiny hands gripping his school uniform. He felt the weight of her trust, and it was almost too much for his young heart to handle. He had wished to be a hero, but he had never imagined that his wish would come true in such a bizarre and overwhelming way.

The group of students looked at Eri with a mix of awe and curiosity. They had heard about the little girl that was saved from the Eight Precepts of Death, but seeing her in person was something else entirely. The teachers had warned them to be gentle and not to overwhelm her with questions, but their curiosity was like a beacon, drawing them in.

Midoriya was the first to approach, a shy smile on his face.

Izuku:Hi,Eri!You remember me,Right?

Eri looked at him and recalled who it was the one who said he's Called deku. She nodded slowly, still sniffling. Izuku took a step back and (Y/n) stood up, holding her in his arms.

??: You don't have to be afraid,We're friends.

Eri looked up and saw a young Teen Girl with long white hair pulled into twin-tails held with shuriken. She has red eyes,Just like her but she was wearing a patch over one of them.

??:I'm Yagyu,(Y/n)'s Girlfriend. And we're all here to help you feel welcome.

The girl introduced herself as Yagyu, her voice kind and gentle. She offered her hand to Eri, who took it tentatively, her curiosity piquing. The room was filled with whispers as the students tried to get a better look at the new arrival. (Y/n) felt a twinge of anxiety, remembering his own whirlwind transformation from a carefree toddler to a teenager thrust into the world of heroics. He had wished for power, for a chance to make a difference, and it had come at the cost of his childhood innocence. Now, holding Eri, he understood the gravity of his wish.

The class began helping Eri through the day-to-day activities, with Y/n acting as her guide and protector. Each student had a unique approach to interacting with the young girl, some more cautious than others due to her traumatic past. Eri remained mostly quiet, observing the world around her with wide eyes filled with a mix of fear and wonder. The colorful hallways of Kurosu World High were a stark contrast to the cold, sterile environment she was used to, and every sound was a potential threat. Yet, in the midst of this chaos, she found solace in the gentle embrace of her newfound family.

One evening, as Eri sat on the floor playing with a set of action figures that Izuku had lent her, she picked up one that looked suspiciously like (Y/n). She stared at it, her thumb tracing the tiny hero's face. It reminded her of the warmth she felt when he held her, the strength in his arms, and the soothing whispers of his promises. She looked up to see him talking with Aizawa-sensei in the corner of the room, his expression serious. The figure felt heavier in her hand, and she realized that she had inadvertently bent it out of shape. A soft knock at the door broke the silence, and in walked a young man with a quirk that allowed him to manipulate gravity.

The gravity-wielding student, Fumikage Tokoyami, offered Eri a small smile. He was one of the few who knew what it was like to be feared because of his power. He approached her slowly, his dark hair seeming to swirl around him as he moved.

Fumikage: Hey, little one. Mind if I join you?

Eri looked up at him, and something in his kind gaze made her feel less alone. She nodded, and he sat down beside her, placing a hand on her shoulder. The weight of his touch was comforting, and she found herself relaxing slightly.

Fumikage: I know it's scary, but we're all here to help you. You don't have to be afraid.

Eri clutched the action figure tightly, feeling a warmth spread through her chest.

Before it scene changed to iida and the rest of Class 1-A noticed (Y/n),Yagyu and Eri coming down the stairs. Upon seeing Eri in her new clothes, many of the girls complimented her, saying how pretty she looked, to which she smiled and giggled.

The Trio sat down on the couch as the chatter died down.

Iida:e were just discussing some new rules that must be established now that Eri will be staying with us.

Iida said.

Iida:So far, we have decided that all of us will assist in taking care of her and teach her various things, such as table manners, how to handle being out in crowds, how to dress, etc. In terms of where she will sleep, it has already been confirmed that she will stay in (Y/n)'s room as he is her temporary guardian." At this,The entire Class both nodded their approval knowing how innocent the toddler teen is.

Iida:I believe the next step is to create some rules. First, no perverted actions or words are to be used around Eri.

He took a moment to shoot a glance at Issei Hyoudou,A member of 1A and The BIGGEST Perv on Campus. He nodded solemnly,his face devoid of his usual lecherous smirk.

Issei:I Know,You Guys Should Know Even I have standards!

This brought a small chuckle from the class,even (Y/n) couldn't help but laugh a bit. Eri looked confused but (Y/n) assured her it was just a joke.

Midoriya:Yeah,Issei is just.....our resident comedian.

He said with a smile.

Iida:Second!

Iida said as though he didn't hear The perv.

Iida:No profanities or curse words of Any kind are to be said when Eri is in the same room.

Kaminari:ear that, Bakugou?

Kaminari asked, shooting a smug grin at the explosion user.

Kaminari:Gotta cut back on the swearing for Eri.

Bakugou:You shut your fu-

akugou shouted, but stopped when he saw Eri looking at him.

Bakugou:your fu-fu-fudging mouth, Kaminari.

Bakugou finished, struggling to get the words out through his clenched teeth.

Kaminari:'Oh, this is going to be good.'

Kaminari thought with delight.

Iida:Third, no antagonizing someone just so they slip up and curse in front of Eri.

Iida said making Kaminari sad.

Kaminari:Whelp, there goes the fun in the second rule.

Kaminari said sadly, while Bakugou returned the smug grin.

Iida concluded As he said....

Iida:We ALL must be sure to spend some time with Eri. We may be training to be heroes, but we also have to remember that Eri will need someone to play with her and teach her to have fun. Everyone agree on these rules?

All the students nodded their heads in agreement; all of these rules seemed fair and reasonable.

The rest of the day consisted of teaching Eri manners like eating properly, saying "Please" and "Thank you", and asking politely for what she wanted. To everyone's surprise, Eri turned out to be an extremely fast learner. After being taught how to use a fork, spoon, and knife to eat her food instead of eating with her hands, she immediately picked up on it.

Soon, the clock in the living room read 8 o'clock at night. Eri suddenly yawned.

(Y/n):Guess it's time for you to go to bed.

(Y/n) said as he lifted Eri up and began to carry her up the stairs to his bedroom as Izuku,Ochako and Yagu soon followed behind them, the rest of the class waving goodnight.

When they reached (Y/n)'s room, he let Eri and the girls in and closed the door to give them time to change Eri. When they were finished, Eri was in a simple pink nightgown.

Yagyu then took her to the bathroom to help her brush her teeth. Soon, Eri was nestled in her little bed with (Y/n),Izuku, Yagyu and Uraraka kneeling down next to her.

Ochako:We got you this little nightlight,

Ochako said as she showed Eri a nightlight that had stars engraved into it.

Ochako:That way....if you ever need to get up at night or have trouble sleeping, the light will always be there to either guide or calm you.

Eri just sat in her bed silently, eyes following her fingers as she traced the design on the blanket. Then, in a voice so quiet that they almost missed it, she said that this was the first time she had something like this as Izuku asked...

Izuku:A nightlight?

Midoriya asked curiously but Eri shook her head.

Eri:A bed.

Hearing this,(Y/n) looked at the others with concern. Sometime during the day, they had forgotten that Eri never had the best childhood. Being held prisoner by a group of villains, experimented on every day, abused by a man who had no regard for the lives of others...it was a life no person should ever have, let alone a child.

Seeing Eri's saddened look, Midoriya placed a hand on Eri's head.

Izuku:I know you didn't have the best life, Eri.

He said in a soft voice as (Y/n) agreed.

(Y/n):Izuku's Right....Nobody should have gone what you went through. But it's going to be alright. Overhaul is gone, you've been freed, and you are surrounded by people who love and care for you.

EriEven you?

Eri asked the four students.

Ochako:Even us, Eri.

Ochako said with a smile.

Ochako:Our Class will care for you no matter what happens. You'll finally be able to live your life like you should. And we promise that we will never treat you like they did.

Eri:You promise?

Eri asked as Yagyu smiled and let out her pinkie finger and said "Pinkie promise"

Eri locked her own pinkie with Yagyu's and gave the Shinobi a small smile.

(Y/n):It's time for bed...Goodnight, Eri.

Izuku and Ochako already left as Lur Toddler teen leaned forward and hugged the little girl.

Eri:Goodnight, Papa.

Eri said.

Yagyu:Goodnight, Eri.

Yagyu said as she too leaned in and hugged her.

Eri:Goodnight, Mama.

Eri responded sleepily. And with that, she laid her head on the pillow and closed her eyes and As soon as they were sure she was asleep, the four plugged the nightlight into the wall, turned off the lights, and slowly closed the door so as not to wake her as they stepped into the hall and rejoined their Classmates.

(Y/n) couldn't help but smile at how happy Eri seemed to finally have a place where she would be loved. She wouldn't have to worry about anyone hurting her or experimenting on her for their own personal gain. She would be able to live a happy life with Class 1A and Himself being her pa-

He stopped as he froze recalling what Eri called him as Yagyu did the same recalling what Eri called her.

Asuka:Hm? What's Wrong?

(Y/n) Stuttered what exactly was wrong....

(Y/n):Eri.......She Called Me "Papa"

Yagyu:And she called Me "Mama"....

The two answered as the Entire dorm was so silent you could hear a pin drop. Every one of the students were looking at the couple with dumbfounded faces. Even Bakugou took a moment to look up from his history book to look at the two before....

Mina:OH MY GOD!SHE CALLED YOU "MAMA" AND "PAPA"?! THAT'S SO ADORABLE!!!

She was shushed and reminded her that Eri was sleeping as Leon said...

Leon:It actually Makes sense for her to call you that,You are her guardian now after all.

(Y/n):But it feels weird,I mean,I'm only 4!!!I'm younger than she is!

The room was abuzz with whispers as the students processed the news but not from what he said because they still thought he was referring to his Mental age,Not his LITERAL Age since he was a Four year old in a Teen's Body as he said...

(Y/n):And what about what she called Yagyu?

Asia had an answer for that as she said....

Asia:Maybe for both,it's like this....she called you "Papa" Because Your now her legal guardian and As for Yagyu,She's Your girlfriend, so I guess in Eri's eyes, that makes her a 'mama' figure.

(Y/n) nodded, his mind racing with the implications of Eri's words. He had never thought about the possibility of becoming a father, let alone being mistaken for one. The pressure of his new life was already immense, and now he had to navigate the complexities of being a parental figure to a traumatized six-year-old girl. He felt the weight of the world on his shoulders, and all he wanted was to be the hero that Eri deserved.

The next day, classes resumed at Kurosu World High, and (Y/n) found himself juggling his schoolwork with his new role as Eri's "Papa".

The students of Class 1-A were supportive, each one taking turns to spend time with her, helping her to feel more at ease. However, the whispers and glances from the other classes were unavoidable. Some were envious of the attention Eri was receiving, while others were simply intrigued by her tragic backstory and the mysterious nature of her powers.
