Our Hero Academia! Ch1: I wanna become a hero! part 1

...

Tsuna ran to school, he ended up waking up late once again. With his mother being a famous news reporter and his father being a professional hero, they mainly were never home. Of course, Tsuna loved them both the same, regardless of them not being able to actually give him time to be with anymore than when he was a child. Though he didn't need anymore time together with them since he's actually 14 now attending the same school as Midoriya and Kacchan.

As the school was approaching Tsuna saw a familiar green haired boy he loved.

"MIDORIN!" Tsuna shouted his rare nickname making the green haired boy turned with a rather gleeful expression on his face. Tsuna instantly knew his expression was from watching the fight this morning he received notification on his cellphone that his mother gave him. As much as Tsuna didn't want it, it was a rare model no one could get but top heroes. It ran alerts and updates like no other smartphone and had a full body scanner installed to record your body data, like heart rate, blood pressure, and much more features.

"Ah! Good morning Tsu-chan." Midoriya smiled happily as he stopped to let the brunet boy Tsuna catch up. When Tsuna finally did he gave his signature smile at him, Midoriya really must be in a happy mood from the morning fight, he even used the brunet's famous nickname.

"Good morning Midorin! I take it you saw the fight with the villain today at the train stop?" Tsuna spoke as they began to walk in school casually, both right on time as others were walking in as well.

"Mmhm! It was so cool! Kamui was fighting this villain but the fight was intervened by this new hero called Mount lady. Too bad! Though her quirk was amazing! I wonder if she could freely decrease and increase her size or its only that way." Midoriya couldn't help but rant happily as Tsuna could only giggle as the others habit came out. Even if he didn't enjoy seeing or watching, he was really supporting of others decisions.

"I hope you figure out soon to place down in your notes!" Tsuna replied brightly as his honey caramel eyes shined only to make Midoriya blush and smile shyly. He was actually really happy that Tsuna never judge him for being quirkless and actually understood him for having no quirk as well but not only that, the brunet supported his decision in becoming a hero.

"Hehe, yeah." The conversation ended there as they made it in class and began to move to their assigned seats. Tsuna could feel the rude glances on them when they entered but he paid no mind and happily walked to his desk not bothered at all unlike his self-conscious friend who stiffly moved and sat in his seat. Making Tsuna send small gazes of reassurance and a silly 'you can do it' fist pump only making Midoriya smile at the boy.

"Good morning Kacchan!" Tsuna spoke as he sat literally right by the blonde boy who was half asleep with his legs kicked up on the desk. His rather dark red eyes opened slowly and turned their gaze to the brunet smiling at him happily. His lips formed into a small smirk not cocky or rude compared to all the other ones he does. Tsuna's full attention on him making his mood actually better this morning. He didn't want the brunet's attention somewhere else right now but him.

"Good mornin' Tsu." Katsuki spoke as their gazes never departed one another for a moment. Tsuna decided to break his eyes away to roam through his bag and hand over a blue wrapped bentou for the cocky blonde.

"These are left overs of the spicy curry my mom made. It's just simply too much, it's hard to eat by myself." Tsuna spoke up as the blonde's eyes trailed to the bentou before he removed one hand from his head to grab it. Katsuki absolutely loved Tsuna's mother's cooking, it was amazingly good every single time he ate as if heaven was melting in his mouth.

"If you insist on handing it over." Katsuki smoothly replied as if he didn't actually want it but Tsuna knew better than anyone else.

With that Tsuna's attention turned to Midoriya who was staring up over at them. The brunet instinctively smiled as the other shot his hand down and started scribbling something in his notes furiously, with a soft giggle Tsuna's attention trailed back to a now unhappy Bakugou. The brunet gave a small sheepish smile as the other clicked his tongue in a upsetting matter. 'Why was he so mad now?' Tsuna pondered questionably but soon the teacher came in to start their class.

...

...

Midoriya turned his gaze over to Tsuna who was happily chatting with Katsuki, he was glad his other friend didnt hurt the brunet in any way but seeing Tsuna being friendly with everyone but him made him rather upset. Soon the boy shook his head, 'why am I thinking such things?' he pondered as his green wide eyes turn back to Tsuna who was now looking over at him with a smile. This made him blush deeply as he quickly turned away from Tsuna, who caught him looking over. 'I thought my heart was gonna stop!' He thought as he started furiously scrambling in his notes and accidentally writing the brunet's name.

...

...

Class was rather dreadful, Tsuna was completely no good with keeping up. He wasn't a genius like his blond friend who literally continued to sleep throughout it.

Or Midoriya was hiding himself in his arms while continously roaming and scribblingthrough his notes. Tsuna gave a small pout as he gave up in solving the mathematical problem in front of him, it was simply too hard. He ended up pursuing out his lips and placing the pencil on top to balance it while continuously staring at the teacher.

Katsuki glanced over at Tsuna, staring at the brunet who had rested his head on both of his hands while trying to keep balance of the pencil. Those cute soft lips puckering out as his full concentration was on the teacher, the blond could only watch as he could feel his cheeks almost flare if he didn't suppress it down. Tsuna stopped with a sigh and caught his pencil with his hand, his eyes soon turn as the blond could only shut his eyes in reflex.

Tsuna gazed at the blond, he felt someone looking at him but to find out no one was. Odd. He didn't think of it as his attention drawn back to taking notes, Katsuki almost let out a sigh in relief. He was glad Tsuna didn't catch him staring, his eyes went back to the brunet as he was taking notes. Tsuna always hanged out with Deku, why couldn't he bother to always stay with him instead. He turned his eyes to the teacher, sleep no longer hitting him, so he decided to listen boredly.

...

...

"You bunch are seniors now in middle school! You really have to think a about your future!" The teacher spoke making Tsuna only to flinch visibly, there was no way this wasn't going to end well.

"I'm gonna pass out handout's for your future plans now. But... You're going to be hero's yes?" The teacher smiled as he tossed the papers behind him, he kept going on about how great the quirks are in class, Tsuna already knew there was no way he was getting into any good schools from his grades and studies.

"Hey Teacher don't lump me with everyone else, I'm not going to be stuck at the bottom with the rest of these rejects!" A voice spoke rather arrogant making Tsuna to only sigh lightly, it really wasn't going to end well, not with Katsuki's personality.

"Hey Katsuki! That's uncalled for!" Every started to complain as Katsuki only laughed mocking at them.

"Shut up you extras!"

"If I remember correctly isn't Bakugou going to apply for U.A?"

"Really!? Isn't that the super hard school that has a failed 79 percent of their examinees!?"

"I heard its the top school."

Thus, let the beginning of bragging hence.

"Thats why you are all extras! I aced the mock test and I'm the only one in the school who is possible to go." Katsuki smirked as he jumped onto his desk, the poor brunet right by him could only sigh as he tried to hide his own embarrassment for his friend.

"I'll definitely surpass All Might and become the top hero! My name will be inlisted on top of the list of earners!"

"Oh yeah, didn't Midoriya wanted to go to U.A., too?" The teacher interrupted on purpose.

The whole class got quickly quiet before everyone started laughing hysterically at Midoriya all besides the angered blonde male and the brunet who could only frown at the entire class.

"Pfft! Midoriya!? No way!"

"There is no way you can get in with just studies!"

"That's not true! They change that rule a long time ago!" Midoriya spoke nervously as he tried to defend himself only to be intervined by a enraged blonde.

"DEKU!" Katsuki slammed his hand on the boy's desk using his quirk as the poor green haired boy could only fall back from the impacted of the explosion, soon the blonde continued to talk after his loud at burst.

"You're below the rejects, you're quirkless! How can you even think to be equal to me!? HUH!?"

"Wait Kacchan! It's not like I'm trying to compete with you or anything! Really! It's just been my dream to go ever since I was little.. And you never know unless you try right?"

"What do you mean you never know unless you try!? What the hell can you do!? You quirkless!" Katsuki shouted angerily before Tsuna suddenly appeared in front of Midoriya with his hands spread out.

"Stop it Kacchan! Leave Midoriya alone, along with all of you! Even you Sensei! How could you just let all of this happen while we are still in school, you have no right to be teaching then!" Tsuna frownedas his eyes flared orange for a brief moment but it was unnoticable by most. "Kacchan you idiot! Stop picking on Midorin! If you don't stop I'm never going to talk to you again!" He soon turned his attention back to Katsuki, leaving the blonde wordless from the brunet's outburst. All he could think about was what Tsuna said as he stood in a complete petrified state.

Tsuna soon turned around to Midoriya who was as well lost for words but had an expression of glee, "Um.. Tsu-chan.." He mumbled with a small smile as Tsuna helped him up. "T-thank you."

"Dont worry about it! Honest! Besides, dont let anyone stop you from losing sight of your dream! I still think you'll make a great hero! No matter what!" Tsuna smiled happily only making Midoriya blush as he felt relieved inside for having such a great friend.

"OI! Tsu!" Katsuki finally broke out of his trace as he grabbed the boy's arm, the brunet could only turn his head around to see a facial expression he never witness before. "Tsu. What's so great about Deku? Why are you always defending him? He's quirkless! He'll never be great! I'm definitely going to be the top hero and become famous! Everyone will admire me more than anything!" 'So why...' Katsuki clenched his fist together as his teeth was slammed shut, all he could do was stare at his childhood friend who simply stared couldn't read the emotions on his friend's face, it was a keen to hurt, sadness, frustration, and desperation. Seeing such an expression rather gave his heart a tight squeeze, because Tsuna knew he was the reason why his friend looked so hurt.

"You should treat him better, I thought we were all friends. Midorin treats you like one, so... Why cant you?" Tsuna spoke gently as if he was trying not to hurt his friend more but such expression only told him otherwise.

Katsuki went quiet as Tsuna could only stare at him with those sadden eyes, 'It's because I lost you to him.' He thought but of course, he wasn't going to say it. 'Tsuna was my friend first, then Deku came along and ruined it all! He's quirkless! you should hang out with me! I'm going to be the best but yet he's with a normal person who doesn't even have a single quirk! Just a dream that can never be fufilled!'

"Alright, everyone quiet down, and who ever is up please get back in your seats!" The teacher finally spoke, breaking the tension in the class.

"Oh right, sensei! Let's have a chat afterschool ok?" Tsuna smiled cruelly as the teacher could only sweat bullets, the so called quirkless brunet was actually the son of the Vongola company who produce all of the latest techonology for hero's and normal people alike. Not only that but his father was the one of the best heroes and is well known for helping the poor and his mother was the best reporter everyone admires.

"Ah, yes Sawada-san." The teacher spoke respectfully as they took their seats.

Katsuki could only stare blankly at the teacher who was beginning to speak about their job forms in the future once more.

"Katsuki-kun, this is Tsuna. For a week he's going to stay with us ok? He's parents are busy working so he doesnt have a place to go." Katsuki's mother spoke as the boy could only stare at the shy brunet in front of him. Those soft but wide caramel eyes stared back at him in wonder.

"No hurting him ok? He's oddly shy but he's a good boy, I'm sure you two will get along well."

Katsuki nodded as he walked over to the boy and held his hand out, "Do you want to play with my robot?"

Tsuna could only stare at the boy cautiously, soon he deemed him safe before taking the blonde's hand happily. Katsuki smiled as he guided the boy to his room. It was rather messy as all sorts of toys of heros and robots where scattered across the floor. Careful, he led the boy around easily, before getting to a small but safe enough spot to play without them sitting on anything unnecessary.

"This is my robot! Cool huh?" Katsuki spoke as he shown his most prized possession happily to Tsuna who can only admire how cool it looked. It wasnt anything amazing from an adults view but the robot had action and voice buttons making noises as it moved and that alone made it amazing to the two boys. Tsuna could only shake his head in agreement to the blonde haired boy with a warm smile on his face. Katsuki could feel suddenly embarrassed by that smile that seemed to glow.

"I'll let you play with it! You can help me defeat these heroes." Katsuki grinned as Tsuna nodded once more as Katsuki gave him his favourite robot.

"Mwahaha! You'll never defeat the great robot Katsuki and his sidekick Tsuna!" Katsuki yelled as Tsuna moved the robot as if it was talking. "Take this! Seeking rockets! Boom! Boom!" He continued as the brunet could only giggle as he acted like he was firing at the heroes. "Ahh! Someone help!" Katsuki spoke for the heroes as he made them run away. "Yes! We did it! We drove them away!" Soon the blonde turned to Tsuna who seemed to not look so well.

"Tsuna?" He questioned before the boy suddenly collasped on the floor. "Mom! Mom! Help!" Katsuki panicked as he quickly rushed to go get his mother.

...

...

"The doctor told me it's fatigue, he hasn't been sleeping and eating much he said." A voice spoke sturring the brunet awake, his eye lids were heavy as he could only feel them suddenly close once more.

"Mom, will he be ok?" Another voice spoke, Tsuna instantly recalled the little boy's voice. It was Katsuki, the blonde boy who he was playing with.

"Of course Katsuki-kun. He just needs rest."

"Alright mom." With that the brunet could only fall asleep once more.

...

"My mom said you should eat! Boys who dont eat can never grow upstrong!" Katsuki spoke as he shoved a spoon of rice porridge into Tsuna's mouth. Its already been 1 year since Tsuna has been in the hospital for an unknown reason, the doctors dont understand whats going on with the boy but its as if his body is rejecting anything they put inside of him.

"I dont feel like eating..." Tsuna muttered after swallowing the spoon full. He gave a small pout to his now bestfriend who could only smile back in return.

"Come on Tsu! You need to eat! The only time you ever do is when I'm around!" Katsuki remarked making the boy only pout more.

"Fine.. Just a little more and I'm done." Tsuna finally agreed as he let the bestfriend feed him once more. Apparently, the only time Tsuna could eat or drink is if Katsuki was around. It was the only time his body didnt reject what his friend gave him and thankfully too.

"Tsu! Dont worry ok? I'll always be here to help you! So get better!"

"Ne, Kacchan. Why do you pick on Midorin?" Tsuna asked making Katsuki only to stop studying and turn his head.

"Huh?" Was all the brunet recieved back as a somewhat rude comment.

"Don't huh me! Geez!" Tsune pouted lightly making Katsuki's glare somewhat lighten at his friends rather cute expression. The brunet blinked before tilting his head slightly to the side, "Kacchan?" He spoke once more making the blonde only to snap out of it.

"Shut up." He quickly spoke as he tried his best not to blush or stammer trying not to think about seeing his friend in that kind of way. Secretly, he developed those kinds of feelings. It just sort of happened when he took care of the boy for a long time when he was bed ridden. Tsuna was just so helpless and cute, like a kitten who was lonely.

"Kacchan! Geez... Poor Midorin. What did he do to deserve such a thing." Tsuna sighed as he flopped back on his friend's soft bed staring up at ceiling before turning his eyes towards a picture he drew of the two of them on the side of the bed. "I see you still have that picture. Is it some kind of treasure?" The brunet giggled in a joking matter as Katsuki got up out of the chair and walked over to Tsuna who was laying down.

"Yes. It is." He spoke seriously as he got on top of his bestfriend, both arms resting by Tsuna's head. Katsuki couldn't help but give a smug smirk as the boy underneath blush deeply.

"G-get off!" Tsuna shouted as he tried to shove the otheroff but the blonde didn't budge. Instead there was a rather compassionate soft gaze from those red eyes, making the brunet rather slowly drown in those eyes.

"You're wide open Tsu." Katsuki smirked as he leaned forward and started tickling his bestfriend on the sides, his weak spots.

"Noooo! Haha... Stop! Haha.. I can't breathe! Help!" Tsuna's words were all over the place as he continued to laugh hysterically, trying to kick, shove, or bite just to get away.

Katsuki soon stopped before getting up and leaving the brunet to compose himself over the little session he recieved.

"I'm gonna get a drink." The blonde soon slipped out the door, escaping from the soon pillow that was thrown at the door by the brunet with a pout on his face.

"KACCHAN JUST WAIT UNTIL I GET MY HANDS ON YOU!" Was all Katsuki heard from Tsuna as he rushed to the kitchen.
