Yagi Household, Musutafu

Izuku's POV

Age Six

     I was woken up by Papa, he smiled down at me as I woke up in my All Might pajamas. "Get up, Izuku. I wanna take you somewhere today." I sat up and rubbed my eyes, "Mmm? W-Were are we gonna go, Papa?" He smiled at me, "It's a surprise, I already talked to your mother. You're gonna meet some friends of mine." I got out of bed, "F-Fwiends?" He nodded, "Yep. They're heroes too."  

    My eyes glimmered with excitement, "Woww!" He chuckled at me and I pleaded, "Can I bwing my journal? Pwease?" He patted my head, "Sure." I cheered and smiled, quickly running around my bed to grab my book. Journal No. 2. I smiled as I came back around and he picked me up. "First, you gotta change out of those clothes though." I whine and hugged myself, "B-But I don't wanna. I wike my onesey." Papa sighed and much to my dismay, helped me out of my clothes and into an All Might shirt, green shorts, and red sneakers.

    "Need help tying your shoes, Izuku?" He asked me, and I bent down to tie them. "N-No, Papa! I can do it!" I smiled as I tied my red sneakers, looking up at him. "See? I dids it!" I pouted as he patted my large amount of green hair, making it cover my eyes. "Paaappaa! I can't see!" "Alright, alright, here. You can see again." He took his hand off of my head and picked me up. "Ready to go meet some pro-heroes?" 

      I cheered and smiled in his arms, raising a fist into the air. "Ya!" "Alright, then." Papa carried me out of my room and out into the living room. I saw Mama and wriggled out of Papa's arms, running toward her and colliding with her legs in a hug. "Mama!" She jostled when the small child collided with her legs, holding onto the living room couch, "O-Oh my!" I giggled and looked up at her and she smiled down at me. "Hello, there my little man!" She kneeled down to my height and kissed my cheek to which I was grossed out and pulled away. "M-Mama!!" I wiped my cheek a bunch, "Don't gives me kooties!" 

   She gave me a weird look and chuckled, "Izuku. Mothers can't give cooties. Love cures it." She hugged me and kissed my head. "M-Mama! Nuu!" She succeeds with her love attack and waddle away from her. "So gwoss.." She just smiled at me and got up to talk to my Papa, "So I hope he has fun on this little surprise." Papa smiled at her and picked me back up. "Yep. I think he will." We were about to leave when Mama suddenly stopped Papa.

   "Don't forget the camera!" She ran over and handed the camera to Papa, he took it and put it in his pocket. "I won't, dear. I'll make sure to get plenty of pictures of our little broccoli." I blushed and whined, "A-Am not a bwoccoli!" I had my head patted again and Papa replied, "Sure you're not." I whined again as we went out the door. "B-But am not!"

U.A. High School, 10 Minutes Later

Third-Person POV

    Izuku currently had his eyes closed by Toshinori's request and wasn't happy about it. "Can I open my eyes now? I wunna see!" Toshinori stopped the car and got out, taking Izuku with him as he walked. "Just a little bit longer, Izuku." The small child nodded and soon Toshinori stopped moving. "Okay, you can look." The child opened his eyes and was quickly amazed by the giant blue building. "I-Is this?!" Toshinori smiled and pet his son's head. "U.A. High. My alma mater. 

    Izuku shook in Toshinori's arms, bouncing with excitement. "Can we goes inside?! Pwease!" The blonde adult gave his son a smirk and the child cheered with excitement while he was carried off into the building. Once inside, Toshinori was greeted by a strange, small, white creature. Part Dog/Cat/Mouse. Toshinori addressed the creature, "Hello Principal Nezu." The white creature approached him with his arms behind his back. "Why hello, Al-" He stops talking as he notices the small child in Toshinori's arms.

   "Does he..um...know?" Toshinori nodded in response, "Little Izuku knows I'm All Might. He's known since he was four, he actually passed out when I revealed myself, sir." Meanwhile, Izuku was looking around trying to find the source of the second voice. He finally saw Nezu as Toshinori set him down. The little boy squealed and hugged the short principal, "F-Fwuffy!"

    Toshinori watched in disbelief and a bit of horror as his son hugged his former-principal, "I-Izuku, you sh-" Nezu cuts him off, "It's quite alright. I'm used to being hugged by little children." Toshinori sighed in relief and Nezu smiled at the little boy when their hug broke. "Your son doesn't look any different than the day he was born." Toshinori nodded and replied, "Yep." Izuku looked back and forth between the two adults as they conversed. "W-Waits, he was der when I was born?" Nezu nodded his hands now behind his back. "Yes, I was, Izuku. Your Mother actually let me hold you." The short animal gave a slight smirk, "Don't think I can pick you up now though..."

   "I'm sure you cans! Lemme jump into your arms, pwease." Toshinori was about to butt-in before Izuku did what he was about to do, but the Symbol of Peace was too slow and Izuku jumped toward Nezu. Not wanting to let the child fall, the principal instinctively caught the child who was a little bigger than him. He strained to keep himself standing as he struggled to keep holding up the child that was of his own body weight. Speaking in a strained voice, "Y-Yagi...he-help..." 

   Toshinori swiftly took the little boy off of Nezu, much to the child's dismay and Nezu let out a deep breath, stretching. "Yikes...that was too much." Toshinori seems a bit panicked and quickly apologizes, "I-I'm so sorry, sir! I didn't expect that Izuku would do that...he's usually well behaved.." Toshinori states the last part in a firm tone while giving his green-headed son a glare. To which the young boy just smiled and giggled, Toshinori letting out a sigh. "Don't misbehave anymore, Izuku. Today is supposed to be fun for you, I'd rather not put you right into a time out when we get home."

    Izuku frowns a bit, fiddling with his fingers. "S-Sowwy, Papa...I was just cuwious." Nezu waves it off, "It's alright...I'm okay. He was just curious, and I'm not that old yet. My back can withstand it." Toshinori rolls his eyes, "Your legs can't." Both adults chuckled and Nezu left after saying, "Have fun, Izuku. U.A. is quite a spectacle." "Well then...let's go meet some pros, Izuku!" 

   The little boy cheered and Toshinori carried him throughout the building, finding the teacher's lounge. In the room stood Midnight, Aizawa, and Recovery Girl. Chatting. Toshinori whispered to Izuku, "Remember can't tell anyone I'm All Might." Izuku nods and Toshinori buffs up into All Might, making his presence known in the room. "Ahaha! I am here...with a child!" The three pros turn around as All Might puts the child on his own two feet. Aizawa sighing, "Ladies and Gentlemen...Dadmight." 

    Recovery Girl sighs, "All Might. Where did you get this six-year-old that obviously doesn't look like you?" "H-He's my kid. Wow. Izuku, son. Do the face." The little green-head smiled, "Da Papa face?" "Yep, the Papa face." Izuku looked to the three adults and did his impression of All Might's face, very much disturbing and creeping the three out. Midnight stammers out, "O-Okay! He's yours! He's yours!" Izuku stopped doing the face and his lip quivered at having creeped the three pro heroes out, turning to All Might. "D-Did I do someting w-wong?" The little boy sniffled and Midnight immediately hugged the child, letting out her apologies while squeezing him. Showing her love for children.

   "Nononono! You're adorable! It's okay!" She sobbed with him, turning her head to Aizawa. "Sh-Shota! Can we keep it?!" He took a sip of his coffee and said bluntly, "No. I don't want a brat, it's All Might's problem." All Might just watched on before Izuku dried his tears and thanked Midnight. "Um...so..Izuku. I can assume you know all of these Pro Heroes before you." Izuku nodded and booped Midnight's nose. "Chu is Nemuri Kayama, Midnight!" He ran up to Recovery Girl. "Chiyo Shuzenji, Wecovery Girl!" He walked up to the man dressed in all black and a gray scarf. Aizawa. 

   Everyone in the room winced when Izuku made a daring move. He CLIMBED up the side of Aizawa like Nezu does and rested his chin on Aizawa's shoulder, giggling. "Shota Aizawa, Eraserhead!" There was a moment of silence where everyone thought Aizawa was about to throw this small child. He took a deep breath and a sip of his coffee before smirking, "Smart kid. I like him." Izuku got down with everyone in shock and walked back over to his Father.

   "So what's his Quirk? This kid must be smart for a reason." Shota sat his coffee mug down on the counter, waiting for a response. "No, he's smart because he studies a lot. He loves heroes. He got a more powerful version of his Mother's. Show them, son." Izuku smiled, "W-Weally?" He bounced a little in excitement and looked to Aizawa. "Mr. Zawa?" Midnight chuckled at the nickname. "Do chu wants your dwink back?" "Um...sure, kid." They all watched in silence as the little boy aimed his right hand at the mug and it moved. Floating through the air until it was secured in Aizawa's hand. 

    Aizawa looked at the mug and back to Izuku. "Ho...ly...shit." Midnight quickly covered his mouth, "Language, Shota!" Izuku turned and looked up at his father, "Papa. Wat does shit mean?" Aizawa looked like he was gonna burst out laughing while Midnight scolded him about ruining the child's innocence. All Might just looked like he wanted to die and kneeled down to the boys height. "That's an adult word, Izuku. You don't need to know it. Don't say it either, okay?" Izuku nodded, "Okay, Papa." 

    All Might looked back up to the three, "Maybe I could surprise some of your students, Aizawa, or catch up with some others here." He just nodded, "Sure, but if any of them pass out, then I blame you." All Might understood and turned to Midnight, "Kayama. Do you mind taking Izuku to the park nearby? I'm sure he wouldn't mind having some fun." She had a wide smile, "Of course! On the condition that I am now Auntie Nemuri." The blonde sighed and chuckled while Izuku gasped and squealed. "Pwease, Papa? I wunna go to da park!"  "Fine, she is...your Auntie Nemuri." 

    Midnight raised her fist in the air, "Yus! Let me go change into civilian clothing and I'll take him to the park." After a couple of minutes after she left the room, she came back in a dark purple shirt and jeans. As well as sunglasses. "Sure is bright outside, and I'd rather not be identified and swarmed by fans." She smiled down at Izuku, "Ready to go?" The little boy nodded and squealed in happiness, taking her hand. "Yes, Auntie Nemmie!" Her heart melted at the nickname and she whispered to All Might, "He's a fucking angel..." All Might whispered back, "No swearing around him...and make sure he doesn't get into trouble. He doesn't do it intentionally, but he finds ways." 

    The woman nodded and took Izuku with her to the park, smiling while the little boy walked with her, hands connected. They walked outside and to Nemuri's car and she looked down at Izuku to ask him a question, "Hey. Are you used to sitting in a booster seat, buddy?" He shook his head no, "Nu. I am a big boy now!" She smiled at him and thought to herself, 'He's so adorable...the way he speaks is so cute too...My heart is gonna explode.'  He got into the backseat of her car when she opened it. She closed it behind him and got into the driver's seat. Then putting her keys into the ignition and driving off toward a nearby park. Built by U.A. actually as a gift to the community. 

    Once she arrived and parked the car Izuku got out of the car and waited patiently. Nemuri got out of the car and locked it. Taking Izuku's hand as they walked into the park, "Go have fun, buddy. I'll watch from the bench." Nemuri smiled as he nodded and ran off into the park, squealing in excitement. She sat down at a bench next to a brown-haired woman with rosy cheeks. "Your little guy is adorable." Nemuri turned her head to the woman and smiled, "O-Oh thanks, but he's not my son. I'm a friend of his Dad, he asked me to take him here." "Oh, sorry. Well, I should introduce myself. I'm Naomi Uraraka." (A/N: We've seen Ochako's Mother before |S2 Ep12|, but either I can't remember her name, or it wasn't said at all. Edit: @Ryan_Nerd7 gave me a great idea. Her name is Naomi.) "I'm Nemuri Kayama. Nice to meet you, Naomi." Nemuri froze up as she said her name and Uraraka's eyes went wide and she gasped, "Y-You're Midnight! The R-Rated Hero!" 

    Nemuri panicked in her mind, 'C-Crap!' She sighed and spoke again, "P-Please be quiet...I didn't wanna be swarmed out here. I just wanted to let Izuku have a nice time.." "Oh, I'm sorry for being loud. I won't give you any unwanted attention." The brown-head hung her head low, a little embarrassed of her outburst. Nemuri sighed and asked her, "So which one is yours?" Uraraka picked her head up and spoke while pointing to a 6-year-old girl with the same features as her who was interacting with Izuku. "That's my little girl. Ochako." 

At the playground

    Izuku was playing and having fun when he ran into a girl with brown hair and waved. "Oh, hai." She waved back too a little nervous of a new person, "H-Hai.." Izuku became nervous too and asked her, "W-Wat's ur name?" The little girl stammered, "U-Um...Ochako Ur-Uraraka..y-you?" "I-I'm Izuku Yagi.." The two socially awkward kids stood there in awkward silence for a bit before Ochako tapped him on the shoulder and shouted, "You're it!" Izuku stood there in confusion for a moment as she ran away from him before he snapped out of it and took chase. "I-I'm gunna get ya!" From the bench, the two women smiled and giggled as they chased each other through the playground before Ochako tripped on an untied shoelace and fell. 

    She sat up in pain, saw her scraped knee and teared up. Nemuri and her mother ran over to see what had happened. Uraraka kneeled down when she got to her daughter and pulled some band-aids from her purse. "Oh no! Don't cry, Ochako. It's just a scrape." She put the band-aid on her knee and kissed it while Izuku, Nemuri watched. "Is that better?" Ochako nodded and rubbed her eyes, "Y-Yes, Mommy." Nemuri took in all this mothering information in case she ever had to put it to use. She stood Ochako back up, "Well. I should get her home, we've been here a while." Ochako pouted a little and Izuku looked up to the brown woman.

    "M-Miss?" She looked at the green-headed boy, "Yes?" "Um...c-can me and Ocha pway more sometime?" She smiled and wrote their address down and handed it to Nemuri before walking away. Izuku looked defeated, the only friend he really had was Katsuki and he was hoping to have gained one more. "Well..guess no new fwiend.." Nemuri noticed his look and picked him up. "Hey, don't look so sad, bud. Look what I got." She showed him the slip of paper that she was given. "That's an address, or where they live. I can give it to your Papa and he can take you to go play anytime." Izuku's frown as quickly turned into a smile as he cheered. 

    She took Izuku back to the car and drove him back to U.A. where All Might was waiting. Nemuri parked her car and got out with Izuku. "So, was he well-behaved?" Nemuri nodded, "He was a very good boy. Oh, here." She handed him the slip of paper and he saw the address. "What's this address for?" "Izuku made a little friend at the park and her mother gave me that." She leaned into All Might's ear and whispered. "More like a girlfriend if you ask me." Izuku heard and blushed, "N-Nu! Stop it, Aunt Nemmie!" Both adults chuckled before Nemuri spoke again. "Ah, well I give you your son back." He thanked her and she walked off. 

    All Might walked Izuku to his car and he poofed back into Toshinori, sighing. "Oh finally, I can be normal." He chuckled and let Izuku into the backseat of his car and he got into the front seat. "So, did you have fun today, Izuku?" The little boy nodded his head, "Yus! Today was really fun." Toshinori smiled as he started the car and drove them home. 

"Good."



(A/N: Holy sh- I wrote a nearly 3,000 word long chapter?! Hope you didn't fall asleep while reading. But Izuku made a new little friend and a new Aunt and possibly an Uncle if Aizawa wants to.

"Not interested, Author." 

Whatever you say. You totally love Izuku. See you guys in the next chapter!)
