Both Katsuki and Izuku were lectured by Aizawa when they returned to the dorm that night. The current narrative was that these two got into a fight, and that sort of news got the teacher agitated enough to place the two boys under house arrest. For one week, they would have to complete a set of tasks set by their dorm mother during those seven days. Asking where he was got All Might to simply ask Aizawa to simply let the boys off with just the week for now.

He begrudgingly agreed to let the boys go to bed before it got too late in the evening. There was still the matter of the missing dorm mother, so Aizawa elected to go searching for the illusive man. It didn't take long for him to find the man, who was sitting outside on the steps that led to the loading area for deliveries. One thing that Aizawa took pride in was how sharp his eyes were for details, and from what he could see there was something that was weighing heavily on Nakamura's mind.

The silhouette of Haru's back through the open door with only the light outside illuminating him made Nakamura look more pitiful than ever. Like a lost kid or stray dog hoping to be adopted. Taking a moment, Aizawa retrieved something from one of the refrigerators that he knew Nakamura kept his stash of alcoholic beverages inside of.

Outside in the evening chill, Haru was smoking his third cigarette while staring off into space. Behind him, he could hear the clinking of two empty glasses and the soft swishing of beer in it's glass bottle. The gift of a glass being filled to the brim with beer was presented to Haru by none other than Eraser Head himself.

"Isn't Emi waiting for you at home?"

"I can't exactly ignore a work call, now can I?"

Aizawa was filling his own glass to sip on while Haru downed most of his glass in one go before setting it back down to be refilled. The next glass lasted longer as the two men sat in solitude from being UA employees. Although he wasn't much of a talker, he was an ideal listener with how little feedback he offered. Without warning, he took the pack of smokes for a stick of his own and started smoking alongside Nakamura.

"Thought you didn't smoke."

"I do when the urge hits me."

More silence settled in as the two of them just kept drinking and smoking peacefully. Taking a mental note of the currently bandaged hand with blood seeped bandages, a question was forwarded to Haru from Aizawa.

"Thought you didn't get into fights with brick walls."

"... I do when the urge hits me."

Just a parroting of Aizawa's response from earlier. From what he could tell, he knew the line about the two boys getting into a fist fight with one another was complete bullshit. Their relationship seemed to have been one that was amicable yet distant in terms of how childhood friends should be. Also, their injuries had none of the tell tale signs of being in a fist fight. It was more likely that they were just thrown around with how their injuries were more in line with taking a hard tumble multiple times.

No singular bruises, no cuts or scrapes from punching or kicking, and far too many skid marks on their clothes with how little these boys were ground fighters. With the look of absent minded misery and injury on his right hand, he could tell that something happened between Haru and the boys that he was well out of his depth of prying into.

Things were ideal for Nakamura being the current dorm mother, him being good at his job while being popular amongst the students as being their caretakers. The personal history that Haru had with some of the students, Aizawa could tell at just a glance wasn't as ideal as others would think at first glance.

"... Listen, whatever it is that got you all involved with that fight; I know you aren't stupid enough to fuck up. We all lose our depth with things here and again, so stop beating yourself up for simply making yourself heard."

Downing the rest of his glass and then taking one last drag of his nearly spent smoke, Aizawa got back up and decided to head home for the evening. The nicotine worked its magic as he went to put away the empty glass in his possession into the sink.

"Goodnight, Nakamura."

He flicked the still burning cigarette at Haru to put in the trash later. His left hand caught the piece of garbage and snuffed it out with just the grip itself. Things were still far too up in the air for Haru to say anything was going to be one way or another. Looking down at his bandaged knuckles, he softly chuckled at how ironic things were from what Arizu said to him.

Just another crack to the unshatterable wine glass that was Nakamura Haru.

Later that Evening

Trying to sneak back into Mina's room without waking her was easy enough for Midoriya. The rustling of the bed woke up the girl and had her asking where he was after feeling the signs of dressed injuries. Turning the lights back on revealed Izuku's poor bandage job to Mina. Since the last few times Izuku got injured, she now kept a fully stocked first aid kit in her room just in case. Redressing his wounds was comforting to the depressed teenage boy. He hugged Mina when she finished fixing the botched first aid by Izuku's self application. Detecting something, she stayed up for a little while longer while listening to Izuku relay everything that had happened.

After hearing him out, her stance on things was somewhere in between sympathetic and apathetic. Though she held him in a gentle hug, the truth of the matter was that she understood where Nakamura was coming from. Midoriya had a habit of not thinking things through whenever he acted out on certain decisions.

Although this trait was something that many heroes possessed, he acted impulsively far too often for the sake of others. His personal life suffered for his thoughtlessness with how close he was to losing Mina over one fight. Now it was his lifelong mentor who was feeling neglected by not only Izuku, but now Bakugou as well.

"You have to start thinking things through, Ikki. Do you think it's fair that Haru-san is ignored so much? He loves you and it's likely he doesn't feel loved back."

Mina covered Izuku's mouth with a hand while straddling his hip like the first time they kissed. He was cross legged while she sat with her legs wrapped around his waist with her torso pressed up to his. She cradled Izuku's head against her chest and allowed Midoriya to embrace her back to listen to her lulling heartbeat.

"Oh, Ikki. He could never hate you. You just have to start thinking things through from now on, okay?"

There was too much going through his head to think about anything else at the moment. Mina was pulled down with izuku to the bed to go back to sleep. The remote to the lights was fished out from the sheets before she arranged the bedding to get both of them comfortable. As Mina was about to close her eyes, a startling question was posed to her by Izuku.

"... After we graduate and we figure things out; will you marry me?"

It gave her so much joy to know that the Izuku she knew and loved was making such a promise to her. This was both him asking to make herself his and himself hers and promising to always honor her desire to see him come home every night to her. Even though it was nothing but a distant goal for the moment, the love that would hold for that day was still very much real to them now.

There was a blush to her face as she embraced Izuku tighter while being thankful for being with Izuku of all people. Still, she couldn't resist the naughty thoughts that she was prone to act upon once in a while.

"Only if you marry all of us, okay?"

Both of them knew that was a given, but Izuku still brought himself face to face with Mina as he promised her the life they both wanted.

"I wouldn't have it any other way."

They kissed for a bit before they spooned each other and fell asleep. Whatever challenges the next day held, they would face them together if they could help it.

The Next Day

Waking up to the lack of Nakamura dutifully setting out a hot breakfast for the class of 1-A was something that everyone never knew they would miss until it was gone. The food was still there and warm for everyone to enjoy, but it didn't satisfy them as much without their dorm mother there to fret over each of their well beings before they left for class.

Some of the students even took an item from the set meal they wouldn't normally consume since Nakamura wasn't there to nag them about keeping a consistent diet. All of them knew of the impossible amount of work he puts into making sure that all their needs are met everyday. Whatever grievances they had about him being a bit of a parent when they wanted to enjoy their freedom were squashed the first time he wasn't there for them.

Izuku and Bakugou only found two notes on the table that instructed them of all the duties of the dorm that were to be done by certain parts of the day. Neither could complain about the tasks set forth by them after what had happened last night. As per usual, Izuku was given a goodbye peck on the cheek by each of the girls while the boys who gave a damn were only able to remain bitter about the discrepancy that Midoriya created in their class.

After everyone had left for classes, the two classmates got busy with the list of tasks that were required of them to complete. For the most part it was a manageable amount of work. That day was primarily the usual daily tasks that were necessary to maintain their dorm building. They both used the steam vacuums to clean all the floors before moving on to their individual tasks.

Bakugou was charged with cleaning the male bath while Izuku managed the female one. Laundry duty was also a thing they had to contend with as Katsuki was stuck with the men's side while Midoriya was tending to the female's. For obvious reasons, this divine was created since only Izuku was the one that the entire female dorm would trust with such delicate material.

Then there was kitchen duty that Bakugou was in charge of. Izuku was barked at for ingredients that Katsuki needed washed and ready for him to prepare for Haru later that afternoon. As they were hitting a rhythm, Bakugou said something that caught Midoriya's attention.

"... It's too rigid."

"Huh?"

His genuine reaction to Bakugou's random statement was one of genuine confusion. His childhood friend elaborated without breaking pace while finishing up the pile of cabbages to his left.

"Your style. When you go from moving around to fighting, it's rigid as hell. You need to figure out how to do both at a moment's notice… I can help you with that, if you want…"

It dawned on Izuku that maybe Katsuki was probably in need of some common ground with someone right now. Both of them were in the same sort of boat since their careless disregard of the same man who felt a bit distant from them at the moment. While far from being a complete recovery, their friendship did hit a new milestone for now.

Later that Day

All the first year classes were assembled on ground beta for their second semester opening ceremony. In comparison to many of the other uniquely heroic activities the students are subjected to, this was a normal school activity that was just per the course. Nezu was the one to start things off with his introduction speech as well as inform the students of their next hero internship.

The lead educator still couldn't resist rambling on about his appearance while advising the students on how they could achieve his level of self care and grooming. This took up more time than what was planned and dragged the ceremony on for an additional ten or twenty minutes.

Thankfully, Nexu cut himself short before he went on another mindless non sequitur. He addressed the events of All Might losing his powers and how the world was standing on its laurels while waiting for the next big threat. The world was not as defenseless as they thought it would be, since the secondary purpose of the internship was to educate the students on the functionality of the Emergency Security Department and how they will be interacting with them out in the real world.

A few murmurs were passed between the students at the news. There hadn't been this sort of course work in the history of education, but it was something that was to be implemented with all hero academies. Criminals and villains were already on the rise, growing bolder and braver with each passing day. That didn't mean that the public was equally as defenseless to the new threat.

ESD work around the country had garnered praise for managing to keep crime at a relatively similar place as things were before the loss of All Might. Along with the rise of criminal activities, ESD arrests increased just as steadily and held down the fort for those in need of their services. Because their work had been increasing along with those of heroes, hero academies all around the country decided to vote in a trial of sorts to get their students more familiar with the government appointed law enforcement.

All the students could do for now was speculate as for what their internships would teach them about the hero work when they become fully fledged heroes. Things progressed normally, with teachers giving their own speeches before dismissing the students to their homerooms.

In the third year classes, there were three very particular students recognized by the student body and teachers as being extraordinary amongst potential great heroes to come. One of them was a recommendation that Nezu himself pointed out for All Might when he first asked the principal for possible successors. A student who would indeed be a good fit; had it not been for the fact the current successor was already well on his way to becoming a hero who will surpass him in the future.

A Few Days Later

For the entire time that Izuku and Bakugou were under house arrest, the amount of times they collectively saw Nakamura in person on one hand. After his outburst, one thing that they were somewhat dreading was the possibility of their future at UA Academy coming to a premature end. Izuku was the first to crack under pressure and called his mother to see if Nakamura said anything to her.

"Izuku? Is everything alright, dear?"

The apprehension in his voice was clear as day to the mother who saw that Izuku was skirting around a topic that he was nervous to ask about. Her patience was limitless when it came to talking to her boy, so after the initial sawward greetings and light banter was when her son went for broke.

"... Has, uh… Has… Has Nakamura-san said anything?"

He knew he slipped up just now since he called Haru by his formal moniker over the familiar one. Instantly, Inko knew that something happened between her son and the man she considered her son's father figure.

"... Izuku, is everything alright?"

"..."

"..."

"... No. It isn't."

All of last night's events were shared with the older Midoriya for Inko to give her a proper recounting of the one sided fight that was instigated by none other than Nakamura himself. After listening to everything that Izuku had to say, she was silent for a moment as the mother was putting her words together for her thoughts on the matter.

"Mom? A-are you still there?"

"Hm? Yes baby, I'm still here."

Another short pause before Midoriya heard his mother take a breath before speaking again.

"Izuku, you've known Haru as this invincible and strong man who was always there for you when you needed him. Right?"

There was a pregnant pause where Izuku didn't answer. He didn't need to answer for how accurate Inko's assumption was dead on the money.

"I'm so sorry, Izuku. To tell you the truth; he's not that kind of man. He only comes off like that because of the experience his life has given him. The reason he was so strong for you was because… Was because he wanted to make you stronger without having to suffer like he did."

Those stories he remembered Nakamura told him over the years in bits and pieces all came back to him. He separated the man from the stories with how confident Haru was while neglecting to remember what had shaped his earlier years. There was no say for Nakamura over whether or not he wanted to be strong, it was that or possibly dying to whoever decided that taking it too far would be acceptable. Nobody could claim that something so horrific or traumatizing wouldn't bother someone during their childhood.

What Haru told him that made him everything he was as a man today was born out of the man's own experiences being passed down. While All for One gave him physical power, the time and experience shared by his lifelong mentor was what pushed him through the tougher moments in life. Being so fixated on the mission he thought was the only one that mattered; it made Izuku neglect how well the man, who practically taught him everything he knew, treated him.

Putting two and two together filled Izuku with shame and self loathing for how little he actually saw in the grand scheme of things. His mentor sacrificed so much, only to be treated like yesterday's leftovers.

"Truth be told, he's scared."

That wasn't something he could even imagine Haru being. There was almost nothing that the man was unable to confront without that confidence of knowing who the winner already was.

"Right now, there's something that scares him more than anything in the world. Something that even I find horrible…"

Taking her pause before saying what it was wasn't out of her need to add a dramatic pause. Izuku could hear his mother fighting tears to share with her son the fear that has even grasped her along with Nakamura.

"... H-he and I… We can't stand the thought of-of losing you. To see you hurt. To see you get injured. It scares us so much, and neither he or I can stop you from taking these risks because… Because we love you enough to let you make your choices."

Hearing the truth didn't make Izuku feel any better. It made him feel like he was sinking into deeper waters where the pressure was squeezing his chest like a vice. Having the excuse of not intending to hurt his parents did little to alleviate his shame. Never once did he consider Nakamura to be capable of breaking under pressure. Now he realized that all of it was for Izuku's sake that Haru walked beside him for so long.

With everything he helped Izuku with, the least he deserved was better than what Izuku did to him during that night. Forgiving the boy for his mistake didn't mean things were back to normal. What Haru offered was the opportunity to regain his trust with time and effort. The expectation that things were just the same as before was an unfair one at best.

They should have never accepted Nakamura's challenge to a fight. When Haru needed affection, they offered their hostility at the possibility of being moved away from the path to their dreams they wanted to take. Another incident of being sidelined by the boy's he loved like his own over their own desires. Not a single moment was spared by either one of them to just slow down enough and think about what made Nakamura act the way he did. About why his endless patience was suddenly all gone in a single moment.

Haru was never the children's priority. He was important to them, but he was far back enough in the line that he felt neglected by those he cared for so much. That realization was what drove him away from the kids of dorm 1-A for the time being. No matter how much love someone has for another, being of no concern to that same person was a painful truth to come to terms with.

"... Mom? I think I messed up…"

Izuku's tears poured freely as he felt the guilt of his neglect come over him. This man raised him like his father, and all he got in return was being treated like the kind neighbor that occasionally came over to help out. He realized that expecting Haru to simply get over it or not even considering how he felt when Izuku fought to return to UA would affect the man.

Inko was questioned over whether or not Haru agreed or disagreed with his decision to return to UA. His mother simply told him that Nakamura said that his opinion didn't matter, since he knew the boy was going to go back no matter what he or Inko said. Even the reason he took on such a challenge being a dorm mother was out of his need to make sure that the children were safe. The realization that he knew nothing about his mentor and didn't bother making the effort hurt like nothing else.

For now, Inko told her son that time was going to be the only thing that was going to help mend things over until Nakamura is ready to talk to him again. Once they hung up, Izuku just sat in the commons until the first few students began to return from classes. Thankfully, it was Jiro who was the first to notice him and usher the catatonic boy to her room. He didn't say much, but snuggling up with the girl with the night did help mend a little of his broken heart.

The Next Day

Bakugou was out on his personal balcony to make his own personal call to a family member. A few short dial tones and he was connected with the familiar voice of his mother, Mitsuki.

"Bakugou? What's wrong?"

"... Hey, mom."

Any mother could see when their child was behaving strangely, and hearing Katsuki sound so worn out did plenty to alert her that something had happened. There was no resistance to her questions that involved yelling or agitation. Instead, it was replaced with a lack of enthusiasm and reluctance. Mitsuki skipped the questions and went for a simple command to get more information out of her distressed son.

"Katsuki, answer me. What happened?"

He took a moment to put his words together before responding to his mother. His response was a question that gave her a need to pause before responding. It was a topic that she never would have imagined her son would go out of his way to ask about after all these years.

"Mom?"

"Yes?"

"Um… What were… What were Nakamura-san and my dad like? Y'know, before?"

It filled her with a cocktail of wildly varying emotions to hear her son talk about his father again. For years, she was fearful that one day he would just try and forget his passed father altogether. Hearing him ask about him gave her hope and joy while reminding her of a painful loss that they both suffered from. The memory of Masara was far more important than any grievance she may have versus the need that Katsuki had to know what kind of man his real father was.

"... Uh, yes. Sorry, give me a moment here…"

Trying to pick out the memories of their interactions wasn't a difficult thing to do. Years of leaving them up on the shelves had made them a bit difficult to remember off the top of her head. Once she had a firm enough grasp of her memories of the two men, the forgotten jovial and cherished moments began to return in their full glory.

"Both he and your father? They were friends. Your dad wasn't a drinker, but Haru was the greatest drinking friend your father had. Those exact words were his and he stood by them. Even still, they got along like a fish to water when alcohol wasn't involved. He was the first new friend since your father graduated from university."

What Katsuki said to his mentor the other night filled him with even more guilt for being so short tempered. Whatever drove him to spit out such a shallow accusation, he wished anything short of killing him would have stopped him from saying such awful things.

"They were almost like brothers. Haru always made time for all of us and vice versa. He was and is a good man to our family… Even still, I wish he would forgive himself. What happened after that, he still blames himself for."

"... Why? What happened? Did he do something?"

A deep sigh followed by a few moments of silence passed before Mitsuki was able to muster the strength to share the truth. Something that Katsuki deeply wished he knew of before mouthing off to Haru.

"Do you remember the day when it happened? Before what happened."

His silence told her that besides the traumatizing part of that very day, nothing else came to mind.

"After everything and things were looking up, Haru came over to the house while you weren't there. What he told me… He told me that he was responsible for letting your father die."

That revelation didn't sit well with Katsuki at all. She shared how it was Nakamura who directed him and his father to that very same bank where the explosion took place. How he was barely able to resuscitate him before emergency responders got to the scene. For years, he held onto the guilt that he was the one responsible for taking away the boy's father away from his family.

All those conversations that Haru attempted in bringing up the subject of the deceased father suddenly made more sense. He felt a debt of duty to keep Katsuki's father alive in the mind of the boy, no matter how agitated Bakugou got with the man. The memory of getting his haircut from the man and getting the story about Haru's father after asking only once further drove the knife into his chest.

Haru never forced Katsuki to face his grief. What Haru did was offer the opportunity to face those difficult emotions an uncountable amount of times while offering to help Katsuki through those emotions. All he did was throw it back into his face every single time. He was the only one who wanted to help Bakugou with his pain without asking for anything in return.

His mentor never treated him like a villain. Everybody else made assumptions and just treated him as difficult or obsessed with his own power. There were places in himself that he never wanted to be. Whenever he was reminded of his father or felt overwhelmed with all the fighting he got into, the one to help him back onto his feet was Nakamura. He never failed to be there when Bakugou called or didn't call for him. It was like the man knew the boy better than Katsuki knew himself.

"... Is everything okay, Katsuki? Do you need to talk?"

It wasn't a usual occurrence when his mother and him talked amicably, since they were prone to butting heads. As much as Katsuki wanted to talk to his mother about the issue, he held his tongue to shield her from an issue that was his to deal with. Even without his dad, he was taught to accept the consequences of his actions like a man.

"No. I just wanted to hear your voice, mom."

A tender moment that had Mitsuki feeling emotional enough to stifle her tears. They both said their goodbyes and hung up. Katsuki was now well aware of how much of a fuck up he brought upon himself and Haru. He knew better than to push his luck and confront Haru right now. If he knew the man well enough, Katsuki knew that his mentor needed time before they were ready to talk again. There was a conviction he swore upon to prevent himself from making such a careless mistake in the future.

He would be dead before he broke it. That much he knew.

Several Days Later

It was finally time for Izuku and Bakugou to make their big return to the classroom after days of grueling housework. For them, it took a good majority of their day to get their own dorm cleaned to a standard that Nakamura deemed acceptable. He had several other dorms that he was mostly responsible for while completing their workload in a fraction of the time. Although he did get some help from some trusted staff, it was still him as the primary caretaker most of the time.

Their time away from the classroom did not exempt them from the schoolwork that was distributed to the others. Izuku and Katsuki were delivered their schoolwork regularly by their classmates while being dragged to the commons by Nakamura to go over the lesson plans. Haru was distant during their lessons and never strayed from the professionalism that he upheld during his tutoring.

Both teenage boys accepted this treatment without complaint in order to respect their mentor's boundaries. Without even knowing it, they took a major step towards maturing into proper adults they could be proud of becoming. Returning to the classroom was a sight for sore eyes after the days of being trapped indoors for a whole week.

Who knew that having a routine that allowed you to interact with other people would improve one's mood? During homeroom, Aizawa addressed the return of Izuku and Katsuki as an appropriate time for the introduction of several of UA's top third year students to make their introductions.

Entering the classroom were three students with quite the presence about them. They were introduced as the creatively named big three of UA's graduating class of the year. Since the second semester internships were up and coming, they all took time out of their current schedules to introduce themselves to the class of 1-A. Unknown to the class was how impressed the big three were about how much of the first year class was able to get their provisional licenses on their first try.

In the lineup, a black haired student that went by the name of Amajiki was designated by Aizawa to go first. His stare was an intense stare on surface level only. Those more familiar with an actual glare with malicious intent were able to see through the aesthetic misunderstanding that the socially inept older teen was involuntarily displaying.

Nobody had predicted that one of the big three was so socially inept to the point of facing the nearest wall like an abused dog over a simple introduction. Up next was the overly social Nejire. Her presence was one who wanted to approach people to an extremely personal degree.

There were questions that she posed to the class of 1-A that were asked that any self respecting adult would never expect. Behavior more appropriate for someone half her age were intrusively launched towards the classroom as the dense girl was socializing to the best of her abilities. While the rest of the classroom saw the demeanor as adorable, Mineta was about to act in his usual behavior before withholding after feeling a chill down his spine. An involuntary reaction he has accumulated from living under the same roof as Nakamura.

His sudden bout of silence was greatly appreciated by everyone in the room as his constant perversions were greatly unappreciated. Her constant questioning fell to the sidelines as the final student made their introduction to the classroom. Mario wasn't the brightest nor most diligent student in UA history, but there was an element that made him remarkable amongst his peers.

The first thing that he did was an obscure cheer that nobody knew of. This didn't dissuade his unnaturally positive behavior from teaching the first year freshman of his made up call out. This was followed up with an assessment of his own that gave a foreboding feeling with the truthful fact that the first years accomplished something truly unprecedented.

Mirio wasn't as dense as he came off as and acknowledged that his introduction was perhaps a little flat. His initiation for all the students to join him at training facility gamma caught a few people off guard, but it was a request that Aizawa forced the entire class to take a part of. Nobody was aware of the one sided fight that would be their losing battle against Mirio by his lonesome.

Later at UA Training Gym Gamma

Everybody had changed out of their school uniforms and were now all back inside their PE clothes. Mirio was stretching and limbering up while his underclassmen were all still processing what it was that he proposed to be their ice breaker. A straight fight between him and the rest of class 1-A.

They were all hesitant at first since all of them were certain that their numbers were already too much of an advantage. His confidence along with the other underhanded comments from the other third years began to grate against the nerves of the rest of the class. Izuku, Bakugou, and Kirishima were the first three who wanted to take on Mirio ahead of the others in their class. From what they could tell, their senior was a bit of an oddball, though he was far from being an idiot. All of them hit the ground running with each of their powers being activated at the same time.

As Izuku and Bakugou were closing the distance between Mirio and themselves, they all were mentally disarmed at the sight of their upperclassman suddenly losing his clothing by phasing through them. Kyoka lost it and screamed in a panic at the sight of a naked Mirio. Having sex multiple times with Izuku did little to alleviate her embarrassment at the unintentional act of exhibitionism.

Wrestling his pants back on, he apologized for the free show he gave everyone while Izuku took advantage of the opening. Rather than the satisfying resistance of a connected hit, Midoriya's right leg went straight through Mirio's head like it was made out of air. Another volley of ranged attacks phased through the older student's body without him even looking at the potential incoming threat.

After the smoke and dust settled, there was nothing but open space and abandoned clothing where Mirio previously stood. He suddenly reappeared out of the floor and declared his plan to engage the ranged combatants first. Poor Kyoka was again subjected to the full frontal nudity of her senior classman as he was unable to bring his clothes along for the ride. Screaming bloody murder did little to protect herself or her fellow classmates from the beating that Mirio delivered upon them in spades.

"Power!"

Snatching up his pants, Mirio yelled his signature battlecry as he left half of the freshman class lying on the floor in pain. The other students were startled at how quickly he was able to bring down the others in a matter of seconds. Some of the class were already assuming that Mirio was unbeatable before Izuku cut them off.

Midoriya correctly guessed that it wasn't invincibility that gave their singular opponent the upper hand. By phasing through objects, Mirio was able to avoid taking damage at a moment's notice while slipping past his opponent's defenses with little effort.

It was nothing short of a one sided slaughter as the senior made short work of every single student he was up against. Even the ones who were able to last a bit longer due to their training in straight fights were handled with little difficulty. Another few minutes was all the time Mirio needed to end the fight with him as the sole victor.

Later

The apology that was offered by Mirio did little to alleviate the aching sensation in everybody's guts. Being punched in the stomach repeatedly would hurt regardless if one was trained to take them or not. Questioning the class over how powerful his quirk was gave him a unanimous consensus that they all thought he was powerful by himself.

He corrected the naive students by explaining that his power was only as strong as it was due to his precise control of it. Activating his quirk known as permeation made him unable to breathe or see if his head or lungs became intangible. How he was able to launch himself from the ground was due to his quirk launching him if his mass became tangible while still underground. Things like direction and speed were all determined on how he became tangible while still being overlapped by something.

What Mirio wanted to show the inexperienced group was how important it was to understand and learn what they were capable of while they take on their internships. It was only due to his experience that his quirk was one with all the utility it currently had.

"Well said, Mirio. Now, to further drive this point home for all of you, I've invited somebody you know to be experienced in taking on challenging encounters with a permanent handicap."

Behind the majority of the students, the front entrance swung open and introduced the well known dorm mother of UA Academy's dorms. Haru still wore his apron while wearing drop crotch sweatpants and a large black shirt. Many of the students thought that the actual opponent meant for Mirio had yet to appear as Nakamura approached the teacher and stood next to him.

"Heya. I'm the one Aizawa asked to be here."

A lot of startled faces looked straight at the man dressed in a doggy paw print apron at the declaration of being Mirio's next opponent. Several students who were aware of the man's combat prowess were respectfully silent as Aizawa disclosed the experience that Mirio was referring to.

Even if their powers were formidable, none of their powers could match up against someone who had far more experience in combat than they did. Nakamura was the ideal choice since he didn't even possess a quirk to begin with. Having a past filled with violence while being essentially powerless gave him more than enough experience in becoming stronger than the average fighter.

Although hesitant at first, Mirio agreed to the impromptu match orchestrated by Eraser Head. Everybody else gave the two their room as they got ready to scuffle. Haru simply put his apron down while Mirio warmed up a bit before taking position across from Nakamura.

They were facing one another when Mirio took the initiative and began to run directly at Haru. To his surprise, the teenager began to descend into the floor before his very eyes. All the spectators were starting to get nervous as to what Haru's next move would be in response to the senior student's.

His response was to simply take a few steps to his left and stop. It was a completely underwhelming experience for the other students watching. Only Aizawa smirked under his scarf as he figured out that Haru knew what to do already against Mirio. There was a very good chance that Mirio was done the moment he used his power to phase through the floor.

Launching out of the ground threw Mirio for a loop as he couldn't tell where Nakamura was for a brief second. He was barely able to turn back around before seeing an incoming kick that he barely phased through in time. Becoming tangible again only served to throw off the young man's balance again. Once he got his bearings again, Mirio realized what had pushed him backwards.

Haru hadn't followed through with his attack like he initially thought. The leg was still sticking through his head when Mirio became tangible again, collided with his reforming body and launched his head backwards as if it was in the ground with the rest of his body. Mirio had little time to think as he was still stumbling backwards while Nakamura was closing the distance.

Amajiki was left dumbfounded at how quickly Haru already figured out a way to use Mirio's power to his advantage. By only watching permeation work once, Haru already devised a way to throw its users balance off by simply occupying the space that went intangible until the power was disabled. The resulting physics that was usually used by Mirio as a form of offense now served to work in Nakamura's favor.

There wasn't enough distance for Mirio to work with while Haru was trying to close the distance between him and the young adult. Falling through the floor, he was forced to back off from Haru in order to rethink his strategy. Resurfacing was barely an improvement with Haru's incoming fist being the first thing he saw when he became physically tangible again.

The punch went through his head, but what the other students saw that was interesting was how Nakamura followed through with his attack. Haru kept pushing up in order to keep parts of his body overlapping Mirio's intangible ones. This aggressive tactic kept Mirio off balance and on the defensive without any sort of breathing room to collect himself. It was disorienting with how he was constantly trying to catch himself while avoiding the man's assault with his quirk.

Switching things up was the senior student's only hope of getting some sort of counter in order to push back Nakamura. His fist was aimed right at Haru's left side as Mirio used the brief opening in the man's assault to counter his advance.

Mirio was certain that he felt his fist touch Nakamura's shirt. The punch was suddenly thrown to the side with Haru smacking away the counter attack. What Mirio and his other big three members realized was that Nakamura reacted fast enough to touch Mirio's incoming fist just as it became tangible. A reaction speed like that wasn't something to take lightly.

Later

Eventually, Mirio found himself heaving and sweating against Haru while lying on the floor with his back touching the concrete. The girls in the class would have found the image more attractive if Mirio wasn't lacking in comparison to someone they already were intimate with. He wasn't small, but a pond was still lacking to a lake by definition.

Collecting himself, there was no desire from Mirio to continue the match anymore. He conceded the fight to Haru and accepted the help to get back onto his feet while also accepting the pants that Nakamura fetched to help preserve the senior student's dignity.

Off to the sidelines, Amajiki knew better than the others how impressive it was that Haru won in such a one sided manner. His friend was an athletic human being with the ability to use their power to overcome almost any sort of challenge. Seeing someone who was not only more physically adept than Mirio beat the student in a contest of skill was unprecedented.

Nakamura immediately identified an exploitative aspect to his opponent's power and used it to gain the advantage. He would later learn of the tale of Haru's past that explained how this skill of his was a necessity for him to survive as a quirkless child. Perhaps even Mirio was still in need of learning in comparison to someone who had to fight for their right to live.
