Summary: Izuku Midoriya once again finds himself into trouble as he was accidentally turned back being a five-year-old kid.
Timeline: A week after the Provisional Hero Licensing Exam.
Shouta Aizawa also known as the underground hero, Eraserhead already knew that he was going to have a bad day.
He was about to take a nap when his phone vibrated in his pocket. A chat was sent in the group chat of Class 1-A, his advisory class.
Aizawa opened the message slightly annoyed.
Iida Tenya: Aizawa-sensei, please come to the dorm quickly. There's a situation.
Aizawa let out a groan. It was not frequent for Tenya Iida, the class predident, to summon his presence so he know it was important. Whenever there is a problem that has risen among the students, their last resort is their teacher. They always do whatever they can to solve their problems on their own. Just like what happened during the Kamino incident.
He sighed. "I have a bad feeling about this."
It was too early for a Saturday morning. But still, Aizawa immediately went to the student's dorm without further ado.
When Aizawa opened the door of his student's dorm, the first thing he noticed was all of his students were present at the main living room. They all encircled the red couch in the center.
It seemed like no one noticed Aizawa when he entered. All of them were much more focused to whatever was in that couch.
"He's so cute!" The pink-skinned girl, Mina, squealed in excitement.
"Yaomomo, the clothes you made for him fits exactly." Kaminari blurted out.
"It sure is. It makes him cuter!" Hagakure agreed.
"He reminds me of my brother when he was younger, ribbit." Asui said.
Aizawa went over to his students to look at what they were looking at.
"I supposed this is the situation..." Aizawa said dryly.
All of the students were surprised by their homeroom teacher speaking out of nowhere.
"Aizawa-sensei!" Kirishima exclaimed.
Aizawa sighed heavily. He scanned the unconcious boy that was laying in the couch. He looks like he is between four or five years old. The boy has green curly hair. In both of his cheeks, it was covered with freckles. He was wearing a green t-shirt and black shorts that were seemed to be made by one of his students.
There was no doubt about it, that boy is Izuku Midoriya.
It seems like his most problematic child once again found himself in trouble. But then, why should he be surprised? Midoriya seemed to be the embodiment of trouble.
Just as Aizawa was studying the boy, he began to twitch his eyes. The young Midoriya opened his eyes. He started to scan the room with his wide and somewhat fearful eyes.
"W-Where am I?" The young boy asked. "Who are y-you?"
"Relax. We're not here to hurt you." Aizawa was the first one to speak.
"Deku-kun, what do you last remember?" Ochako asked, crouching towards the boy.
"D-Deku? How do you know my nickname?" Izuku stuttered worriedly. "Where am I? Where's my mommy?"
Aizawa opened his mouth to answer the little boy when he heard his other student, Katsuki Bakugo, yelled unexpectedly.
"Listen here, shitty Deku." Bakugo yelled angrily.
With Bakugo blurting out a curse word in front of a child, a lot of his classmates started to yell at him.
"Bakugo! Stop cursing. He's too young!" Sero, among with the others, yelled.
"That was unnecesary!" Iida said while waving his hand, robotically.
Aizawa glared at the students with his red eyes. "All of you shut up."
Izuku eyed the teen with an ash blonde hair while blinking rapidly. "Kacchan?"
"Yes, I am, nerd." Bakugo said angrily. "Listen up, since it seems like you don't remember anything that happened. Right now, you're a fifteen-year-old who's studying at U.A. Earlier, someone has used their quirk on you turning you into a five-year-old. Do you understand?"
Izuku blinked for a moment digesting what he had heard before answering. "What...?"
"Tsk..." Bakugo turned away and started walking out. "My job's done here."
A few people called him back but he still went to go upstairs where his room was located.
"Hi, Deku-kun. I'm Uraraka Ochaco. What Bakugo said is true so you don't have to worry about anything. We're not here to harm you." Ochako assured the young boy with a smile.
"H-Hello..." Izuku said shyly.
"I'm Kaminari Denki, you can call me, Denki. My quirk's electricity."
"Hi, Izuku-chan. I'm Yaoyorozu Momo."
"My name's Tsuyu Asui. Please call me Tsu."
"I'm Todoroki Shoto."
Aizawa heard eighteen of his students introduced theirselves to the young green-haired boy. It would probably be lucky if the boy managed to pick up some five or six names after all that introduction. After all is said and done, Aizawa spoke up.
"Iida, explain what happened to him." Aizawa ordered.
"Of course, sensei." Iida agreed.
"So let me get this straight, you and Midoriya went to buy some food outside U.A. and on your way back a young girl accidentally bumped Midoriya. The girl panicked and then somehow used her quirk on Midoriya turning him into a five year old kid that only remembers his memory at that point?"
"That sounds right, sensei." Iida confirmed. "That is what I explained to the class."
Aizawa groaned slightly and stroke his forehead. He asked to speak with Iida to know the situation in the kitchen so they can have some kind of privacy.
"So how can we turn him back?" Aizawa asked.
"It's pretty easy, sensei." Iida said while he waved his hand. "The girl's mother told me, after apologizing, that it will only last for a few hours. Hopefully, when Midoriya wakes up tomorrow, he is back in his self."
"So it's only for a day, huh." Aizawa let out a relief sigh.
The student and the teacher exited the kitchen and went back to the living room where Izuku was located.
"Really!? All Might is one of your teachers!?" Izuku blurted out excitedly. His eyes beamed brightly and somewhat awestruck by the thought.
"No, silly." Ochako giggled. "He is one of our teachers."
"Our?" Izuku echoed.
"Yes, you're our classmate after all." Kaminari said in a teasing tone.
Kirishima started to laugh. "So ever since you're a kid, you're a fan of All Might? That's so manly!"
"It seems like it is a lifetime habit." Ojiro commented with a chuckle.
The first thing Aizawa noticed at the scene was that there were fewer students. The only ones remaining where Uraraka, Kaminari, Ashido, Tsuyu, Kirishima, Sero, Hagakure, Ojiro, Yaoyorozu, Jiro, and Mineta.
Izuku unexpectedly turned his gaze towards Aizawa. "Hi, mister..." The boy said.
"Hello, Midoriya." Aizawa said. "I'm Shota Aizawa. Hero name: Eraserhead. I'm your homeroom teacher."
Izuku's eyes lit up. "You're a pro hero?"
"I am."
"Um..." Izuku turned his gaze away slightly embarrassed.
"What is it, kid?" Aizawa asked.
Izuku looked at Aizawa with his wide green eyes. The pro hero thought that he was somewhat cute. If there is one thing Aizawa likes, it is cats because they are cute. Aizawa believes that Izuku is even cuter than the cats he owned.
"I..." Izuku said shyly making the hero snapped out of his thoughts. "They told me about All Might being their teacher since they were telling me stories about school and—"
"Geez, Midoriya. Is muttering also a lifetime habit of yours?" Mineta said.
Aizawa spoke up. "Get to the point, kid."
"Can I..." Izuku gulped. "...meet All Might...?"
Aizawa sighed. He knew this was coming. Everyone knows that Izuku looks up at All Might highly. And even though All Might does not admit it, Izuku was surely his favorite student.
All of the students look up to him waiting for his answer.
"Midoriya, All Might retired just two months ago." Aizawa revealed.
"Retired...?" Izuku said with eyes widened in shock and worry. The boy did not expected it coming at all.
"Yes. Nothing lasts forever. Even the symbol of peace." Aizawa said. "But the thing I want to say is... All Might's appearance changed. He became skinny."
"Why?" Izuku asked sadly.
"He fought a villain some time ago. He sustained an injury in his respiratory that cause the change in his appearance." Aizawa answered. "You can meet All Might but I am just warning you."
Silence befell upon the room. All of the students look at Izuku worriedly. The young boy seemed to be thinking about the words he had just heard
"But, he is still All Might, right?" Izuku finally said. "All Might is All Might. I still want to meet him no matter what he looks like." Izuku declared with a smile.
Everyone was taken a back about what the boy said especially Aizawa.
"Aww, Deku-kun. You're so precious!" Ochako said while hugging him.
The others agreed with her also engulfing the boy with a hug.
"I see..." Aizawa whispered.
He walked away from the living room and went outside. He get his phone and dialed the former number one hero's number.
To say that All Might is dumbfounded, was truly an understatement.
"I don't fully understand the situation..." The skinny blond man said. "But I suppose this is him."
Aizawa's eyes narrowed. "No, this is the other five-year-old kid that I found in here today." He deadpanned.
All Might frowned.
Aizawa snorted. "Of course, this is Midoriya."
All Might looked at his now five-year-old succesor. Izuku was hiding behind the legs of Aizawa. The boy scanned the former hero with wide eyes laced with nervousness but somehow it also shows curiosity at him.
He does not blame the boy though. His appearance is really different from his hero persona. He remembered the first time he met young Midoriya. He was hectic and dumbfounded when he found out All Might's secret. But right now, it's no secret. Afterall, he is effectively retired now. There was no need for hiding it.
There were some students encouraging Izuku to talk to him but he seemed to be too nervous.
Earlier, All Might has received a call from his co-teacher, Eraserhead. He explained the situation to him as quickly and smoothly as possible. Also, he had asked him to come to the dorm because the young boy wants to meet him.
"Yo!" All Might said to the boy with a huge smile. He crouched so that the boy can see him clearly.
"H-Hello..." Izuku greeted. He finally left Aizawa and started to walk towards his idol. "You're All Might?"
"Yes, I am." The blonde man sighed. "It's probably a surprise to you..."
"N-No it's fine!" Izuku quickly said. "Aizawa-sensei already explained it to me. I understand."
"You really are a smart boy." All Might chuckled a little ruffling the boy's hair.
Izuku remained still for a moment before looking at the older man's blue eyes. "Ne, All Might?"
"Yes, my boy?" All Might answered.
"Does it hurt?"
No one present in the living room expected those words of Izuku. Even All Might himself has a dumbfounded look on his face. He sighed before answering.
"I think you need to replace does with 'did'." All Might said, sighing. "Of course it did hurt but right now. I am fine."
Izuku was silent for a moment before breaking into a smile. "That is good to hear."
Before any of them could say anything, Aizawa butted in. "I guess I will leave now."
"Already?" All Might asked.
"I've been here since morning. I need to ran some errands." Aizawa said. "And I told you didn't I? There is no need to worry about him. He will be back to normal tomorrow and his classmates will take care of him.
And with that, Aizawa left Izuku with All Might.
"So the two villains crashed down when I used California Smash." All Might told the young boy. "But of course, I had the help of Dave."
"That's so cool!" The young Izuku exclaimed in excitement.
All Might had ended up telling stories to the young Izuku. They were sitting in the couch of the living room. The boy beamed with excitement. Of course, hearing some stories from your favorite hero is enough for him to be excited and happy.
Some of the students were also listening to those stories earlier. But then, they left the two. Others because they have something to do and some simply want to give Izuku space.
"Yes, it is, my boy." All Might said. The stories he said to the young boy made him nostalgic. It seems that his life in America was so long ago.
"Hey, All Might..." Izuku said, almost a whisper.
"Yes?"
"Can I... ask you something?"
"Sure, my boy."
Izuku seemed to be silent like he was trying to formed his question. His little hands clasped the long sleeves of the older man. All Might just waited for him.
"They told me that I am already a fifteen year old and I'm studying at U.A. right?" Izuku said.
"You are."
"C-Can I..." Izuku seemed to be lost for words. The young boy's face formed a frown. He looked up at All Might's eyes.
"Can I really be a hero too?"
All Might was stunned by the question. That was also the same thing Izuku asked him when he first met the boy. His answer that time, was not the answer the boy seeks.
"Pro heroes are always risking their lives... No, I don't think you can be a hero too."
But this time, All Might's answer will be different.
"My boy, permission to go to your dorm room?" All Might asked.
Izuku eyed him curiosly. "Why...?"
"I want to show you something that might have the answer of your question."
"Okay."
The two went on their way to the second floor where Izuku's room is located. On their way, a student had seen the two.
"All Might-sensei," Tokoyami acknowledge. "Hello, Izuku-kun."
"Hi..." Izuku greeted the bird teen.
"Hello, young Tokoyami. I'm going to show young Izuku his door room." All Might said.
"His room is in the second floor on the left." Tokoyami explained and went on his way.
All Might and the young Izuku went to the second floor with the instruction. Izuku was holding the man's hand.
Finally, the blonde man had found the room with Izuku's nameplate on it.
"This is your room. Ready to see it?"
Izuku nodded.
All Might opened the door slowly. The older man clicked the switch and lights quickly beamed the room.
In All Might's perspective, the room looks almost identical to the room that Izuku had in their apartment. All Might did not really mean to peak in to his room back then but curiosity got him.
Young Izuku's eyes glittered in a mixture of shock and awe. The room was full of All Might's merchandise. From posters to action figures.
"It's so cool! It's just like my current room!" Izuku yelled happily.
"You're really a fanboy." That got a laugh from his mentor. "Do you mind if I can search your room?"
Izuku looked up at him and nodded slightly.
The young boy immediately went to pick some of the action figures and inspect it happily.
All Might, on the other hand, started to search for it. He went to search for the desk, cabinets, and his bag but it is not in there. Finally, when he found his wallet on his pants, there it is. He took it out and smiled.
"Young one, come here." All Might called the boy.
Izuku looked at him. "Okay." The boy immediately placed those action figures back on its original place.
All Might crouched and handed the boy a card.
"What is that?" Izuku asked.
The blond laugh gently. "See for yourself. It's the answer for your question earlier."
"N-No way..." Izuku muttered. "It is—!
"It's your hero's license." All Might finished. "You just got that a week ago."
Izuku clenched the card tightly. His eyes were close to crying. He sniffed slightly. "B-But how? How can I be a hero? I'm quirkless..."
All Might let out a heavy sigh. He can't explain to the young boy how the quirk he gave to him: One for All managed to work.
"Let's just say..." All Might scratched his head slightly. "You developed a quirk later in age."
"R-Really? But I have never heard such a thing before. A lot of my classmates already have a quirk before they turned—"
"You don't believe me?" the older man asked.
"O-Of course I believe you!" Izuku blurted. "It was just that... It's a dream come true."
Izuku sniffled. He rubbed his eyes as the tears flowed out. The boy could not believe that the he is living his dreams.
"You are a hero, Young Midoriya." All Might said while hugging the boy tightly to comfort him.
After All Might had left, the five-year-old Izuku was left to be taken of by his classmates. Most of the students enjoyed the company of the boy and told him some stories about their everyday lives.
It was dinner time already. Uraraka and Iida introduced themselves to him as his best friends. The two brought Izuku with them in the dining room. Izuku was next to Uraraka while Iida was in front of them.
"Hey guys! Move the tables together. Don't keep him all by yourself!" Mina pouted.
They move three tables together and there are twelve students in total.
"Izuku-chan, we made you some katsudon." Momo clapped her hands and smiled at the boy.
"It's your favorite isn't it, Deku-kun?" Uraraka grinned.
"Here," Jiro handed the bowl in his front. "Eat up! It's good."
Izuku's eyes lit up. He did not realized how hungry he was. Talking to his idol All Might made him happy to the point that he forgot his hunger.
Izuku tasted the pork cutlet first. "It's delicious!"
They all smiled at the boy's reaction. It was physically impossible not to smile at Izuku's cute face.
"There is plenty. You can always get more" Ojiro said with a smile.
Izuku nodded. He was grateful to them. He was here for a few hours now and all they showed him is affection. They also made him his favorite dish even without him telling them.
Did his older self told them about his favorites? Does that mean he trusted them enough?
Izuku did not have friends. If there is one person he is really close to, it was Kacchan. The only time Izuku spoke to the older Kacchan today was when he first woke up. He trusted the older Kacchan because he is his friend. He will not lie to him. He felt guilty for not talking to Kacchan. He will changed that before the day ends. Kacchan was not in their table. He was in the table at the corner eating with a red-haired guy.
"Are you alright, Izuku-kun?" Iida asked as he noticed the boy was silent.
"Yes, sorry." The boy then again ate his dinner.
A few conversations wasd carried out here and there. Almost all of it was centered at Izuku so he will not feel left out.
"Thank you for the meal!" Izuku exclaimed.
He then left out his seat and walked towards the table where Kacchan was eating. The students eyed the young boy as they noticed who is the person he was approaching.
"What is it, shitty brat?" The older Kacchan asked him.
This of course had led to a numerous people pointing that Bakugo should stop cursing in front of the kid.
The red-haired guy besides Kacchan laugh. "Hello Izuku. I'm Kirishima. Just reminding you since you already may have forgotten."
"Hi..." Izuku said shyly. "Can I seat with you?"
"Of course."
Izuku sat next to Kirishima and Kacchan was in his front. Izuku stared at the older Kacchan's face. Nothing much has changed. He still have his ash blond hair and red eyes. His eyes were still looking angry.
"Deku, you're not here to watch me eat. What do you want?" Kacchan asked the boy with a growl.
Izuku gulped. He was already afraid of Kacchan even before they were kids. And now, he is ten years older than him.
"I just want to ask you something, Kacchan." Izuku said.
"You are already asking."
Izuku looked up to him with a serious face. "Do you know why my hero name is Deku?"
All of the students present at the dining room look at the table where Izuku and Bakugo were located. It was not really a surprise that Izuku asked that question. They anticipated Bakugo's answer.
"You're the one who gave me that nickname..." Izuku whispered nervously.
"Tsk. I know." Kacchan put his chopsticks down. "I gave that name to you as an insult but round face has changed its meaning into 'I can do it'."
Izuku's eyes widened with those words. "I can do it...?"
Kirishima started to laugh loudly. "I can't believe you actually answered him!"
The others also started laughing as they did not actually expected Bakugo to answer the boy truthfully. They all yelled some 'good job' at the explosive teen.
"Shut up you all! I'll kill you!" Kacchan shouted angrily with a growl. "And you—" He pointed at Izuku. "Go back in there!"
"Y-Yes!" Izuku nodded fearfully and left the table of Kacchan.
He went back to the table were he was originally seated. He sat between Uraraka and Iida.
"Did you find a good answer, ribbit?" Asui asked him.
"Yes." Izuku laughed. "I'm just wondering who change the meaning..."
The students eyed each other for a moment before turning into Uraraka.
"Uh... I did." Uraraka answered the boy with a slight blush in his cheeks.
"Really?" Izuku asked.
"Yes." Uraraka giggled slightly. "On the first day of school, I heard Bakugo calling you back then as Deku so I thought that's your first name. I didn't realized it as an insult because I thought it sounded like dekiru."
"I can do it." Izuku said the meaning.
"Yes you can, Izuku-kun!" Hagakure yelled.
"You are a great hero." Shoji praised the boy.
"Merci~" Aoyama exclaimed. "Continue striving to be the best, Midoriya-kun."
They all gave him some form of encouragement. Izuku cannot take it. It was too much. All his life, people always say that he was useless and even crushed his dream of beoming a hero. But right now, even though he did not know any of them, they were saying nice words to him.
He was happy. If this was his future, a future where he had friends and studying to be a hero, well that is enough for him. He was glad that he managed to live his dream and didn't listen to the people who discourage him.
He have friends who listened to him, laugh with him and help him in times of need. They encouraged him to follow his dreams. He was too blessed to have them.
With a huge smile on his face, the young boy said the words. "Thank you..."
After dinner, Uraraka and Iida escorted Izuku back in his dorm room. Uraraka opened the door and turned back to the boy.
"See, Deku-kun! Your room is amazing." Uraraka exclaimed.
"Yes it is. All Might even think so." Izuku said happily.
"Eh, All Might has gone in your room?" Iida asked.
"Yes." Izuku nodded. "He showed me my hero license that's how I know my hero name!"
Uraraka pouted. "Aww... I thought we're gonna surprise you."
"Can you sleep on your own, Izuku-kun?" Iida said escorting the boy into his bed.
Izuku nodded while laying down. "I'm old. I can manage."
"You're only five. It's not that old." Uraraka laughed while stroking his green hair. She gave the boy a kiss in the cheeks.
"Good night, Deku-kun. I hope to see the older you tomorrow." Uraraka said with a blush
"G-Good night!" Izuku was red as a tomato. No one has ever kissed him in the cheeks aside from his mother.
"Good night. Sweet dreams I hope." Iida said smiling.
Uraraka and Iida turned around to leave the boy but he started to talk.
"I'm glad that I became friends with you..." Izuku said sleepily.
The two stopped on their tracks and turned back to the boy. They exchange glances before laughing slightly.
"We are glad too, Izuku-kun." Iida said.
And with that, the two went out of the room leaving the boy to sleep. Hopefully tomorrow, Izuku will be back in his older self.
Izuku Midoriya was going to have a bad day. He can already feel it. He woke up from a painful headache.
And then he remembered yesterday's events.
He threw himself out of his bed and immediately went to the bathroom. He looked at himself straight at the mirror.
Sure enough, he was back being a fifteen years old again.
Izuku let out a relief smile. He quickly showered and brushed his teeth to start his morning. He noticed that it was eight in the morning and he might missed breakfast.
After all is done, nervousness struck him. How would his classmates react now? He said some things that he was not supposed to ask. But still, he managed to open his door and went to the kitchen.
He did not see anyone on his way. They were all probably eating breakfast. When he was near, he realized that the dining room was louder than normal.
He gathered up his nerves and walk in.
"Good morning." Izuku said with a smile.
All of the eyes were turned to him in an instant. The dining room became silent with him arriving.
"I'm sorry for the trouble I cause yesterday...?" Izuku apologized scratching his head.
"Deku!" Bakugo was the first one to react. "You back in yourself, huh!?"
Izuku blushed remembering what he asked to him yesterday. "E-Eh Kacchan—"
"Midoriya!" Mina acknowledge. "I'm glad you are back!"
"You are an adorable child, Midoriya-san." Momo said with a giggle.
"Ha! You should have seen yourself yesterday. You were such a fanboy around All Might!" Kaminari laughed.
A lot of his classmates greeted him and happy that he is finally back on his older self. Izuku of course thanked them all.
He then sat once again with Iida and Uraraka to feed his growling stomach.
"Welcome back, Midoriya." Iida said with a genuine smile and offered a handshake.
Izuku accepted it and said. "Thank you for yesterday."
Uraraka spoke up with a giggle. "As much as I adored the younger you, I am so glad you're back."
"Yeah, I am too."
His younger self is right.
He is very lucky to have them as his friends.
A/N: I just finished My Hero Academia, both anime and manga, two weeks ago and I immediately fell in love with it. Deku is my favourite character.
Thanks for reading!
