Midoriya Izuku IV

"Thirteen sensei...?" Midoriya questioned, his fear making the name tremble from his lips.

His only answer was complete silence.

Midoriya couldn't help but feel his stomach drop. A part of him hoped for a reaction, a faint answer from the Space Hero, a twitching finger, anything. But all he got was the sound of Momo's accelerated breathing and the thundering sound of footsteps approaching.

"Deku-kun!" Ochako yelled, immediately following her friend's faithful voice.

Izuku looked up, forcing himself to push Thirteen's broken image out of his mind and focus instead on Ochako. She looked a bit shaken, her chocolate eyes full of concern and fear. She stopped a few centimeters away from him, placing a firm hand on his shoulder and scanning his wrinkled uniform. The action made his cheeks heat up, still not used to having a pretty girl's attention, much less one so genuinely worried about him.

Once Ochako concluded that there were no serious wounds on Midoriya's body, her scraped shoulders dropped in relief. "I am glad you're okay!" She smiled feebly, giving Killua and Momo a quick once over as well. "All of you."

Midoriya just nodded, unsure how to respond. Ochako's grip on his shoulder loosened, sliding down his arm and hanging limply by her waist. A thin path of blood slid between her fingers, dripping quietly to the floor. Midoriya frowned at the sight, noticing a small crack on her helmet and a lot of dirt on the left part of her costume.

She looked worn out. Hurt. But she was smiling faintly, determined to not make a big deal of it.

Midoriya silently offered his damp towel to his friend, giving a small smile to return the comforting gesture and stay optimistic. Her eyes softened, gingerly taking the torn fabric from his hands and cleaning her arm, revealing superficial scrapes and thin cuts underneath all the dirt. She was okay. Those are just scrapes, nothing too serious. Considering how furious the Smoke Villain had looked, Midoriya should just be thankful his friend had no threatening injuries.

"That was fast, I didn't even see you three coming," Sero greeted Midoriya and his partners from the ground where he sat, an ugly cut marring his leg. Kaminari and Satou, the last students in the area, mindlessly voiced their agreement, tearing their eyes away from Thirteen to send a surprised look.

Midoriya's pathetic smile withered, brows furrowing in an explicit show of concern. While the students' injuries proved to be very minor, Thirteen looked mortally wounded.

"Is Thirteen okay...?" Midoriya asked, not wanting to voice the possibility of death.

"I don't know," Ochako admitted, her smile dropping into a more solemn expression. "The villain used his quirk to reverse Thirteen's black hole. I want to believe it hasn't killed them but..." An uncomfortable pause. "It wasn't pretty."

Killua hummed to indicate he was listening, giving an unreadable look to his teacher's remains. He didn't move or appear to activate any quirk, but his blue eyes suddenly lit up with instantaneous understanding, declaring: "They're not dead yet, just unconscious," and moving on, already scanning the area. Everything was the same, only emptier. No villain in sight.

The way Killua delivered his observation bordered on seeming dismissive, but Midoriya believed him to be serious. Maybe he was being too trusting, but after being saved twice, he was inclined to trust Killua's judgment.

Ochako blinked in surprise, not reassured by the pale boy's deduction. Momo furrowed her brows, looking at her friend with discomfort and voicing the question on the tip of everyone tongue "Yet..?"

"I'm no medic but I don't like their chances," Killua admitted, he sounded more serious, but still not very bothered. Clinically detached, like the doctor Midoriya had visited with hopes for a nonexistent quirk. "I would give them around one hour."

"O-One hour?!" That was not long at all.

Ochako clenched her jaw, trying to keep calm despite her obvious distress. "Are you sure?"

"Positive."

Midoriya bit his lip "How can you be so sure?"

A pause, the slightest hint of hesitance before he let it go.

"They still have an aura," Killua revealed, acting as if the sentence explained anything.

It didn't.

Midoriya and Ochako shared a look, unsure if they should wait for an elaboration, hope for more information that could help nurse Thirteen, or try to improvise something. Judging by the mildly exasperated look on Momo's face, it would be better to go for the second option.

"Infinity girl," Killua started, interrupting Midoriya's thoughts before they even got going. "Your quirk is floating things, right?"

"Yes," Ochako disclosed, a bit surprised that someone still used the over-the-top nickname from the first day of class.

Killua's face darkened as he considered his alternatives. "Can you float Thirteen to the school nurse without passing out?"

Ochako paused, processing the idea and then nodding, determined to help. She ran to Thirteen's remains and gently touched the hero pieces, making them float. The anxiety of carrying someone in such a precarious state made her be extra careful, tightening her hold on the space suit arm and guiding the body to the exit. "I'll do my best!"

Midoriya waved in encouragement, wanting to help but not knowing how. Thankfully, Satou was already sprinting towards the heavy door, opening a clear path for Ochako. His friend smiled in appreciation, wanting to avoid any heavy exercise while keeping her quirk activated. That would tire her out, and she couldn't afford to overwork with a life in her hands.

Momo advised Satou to follow Ochako and help her with any obstacles she may encounter. Satou wholeheartedly agreed with her. Both students were quick to go.

Midoriya ended up staying, not feeling good abandoning his shocked classmates and knowing he wouldn't be able to do anything to support Satou and Ochako with his self-destructive quirk.

"Now that that's taken care of," Killua said, shifting his attention to Sero as soon as the two students disappeared behind the door. "Where is the villain? Haven't seen him around."

Of course.

Midoriya had almost forgotten about it.

Sero looked up after being addressed, slowly shifting his injured leg, grimacing at the movement, "I'm not sure, he just warped away."

"Why would he do such a thing?" Momo frowned. Midoriya fidgeted anxiously in place, sharing Momo's confusion.

"He gave up," Sero stated slowly, focusing on Killua with an uncomfortable look. "Fled the place after the belly laser guy got out and went looking for you."

Momo and Midoriya tensed up, unconsciously stepping closer to Killua. After his clear display of power and wits, they understood how ridiculous the idea of protecting Killua sounds, but they still cared. They had his back.

Killua absorbed the new information with half-lidded eyes, far more intrigued by his classmates' worry than Sero's news. He blinked sluggishly, pushing his personal confusion somewhere in the corner of his mind and diving straight into the more logical questions. "Do you remember how long ago Laser Boy escaped?"

"Around five minutes ago, I think...? Probably longer." Sero said, taking a shot in the dark and relaxing his shoulders. Despite not knowing Killua, the tall student was not oblivious to the overwhelming confidence the pale boy carried himself with. The calm yet powerful presence deeply appreciated in such dire circumstances. "As soon as everyone got warped away, he sneaked out."

Midoriya blinked, "Aoyoma-san sneaked out...?"

Strange, Midoriya thought, he seemed like the kind of guy who would prefer to make a dramatic exit, throwing glitter everywhere.

Guess sometimes fear really conquers all else.

"Yeah, after Zoldyck demolished that smoke man, Aoyoma ran. I saw him inching closer to the door and everything..." Kaminari said, looking oddly nervous. He stared at Killua with both respect and awe but also poorly concealed fear, avoiding direct eye contact. "Good job, by the way, that villain had no chance."

"Of course he didn't. He was weak," Killua agreed easily. His word choice sounded like bragging but his tone was far too mellow.

"Yeah..." Kaminari mumbled, staring at the place where Thirteen's broken body had been with palpable unease. "Weak."

Midoriya felt a twinge of unease. Killua may be blunt and detached, verging on insensitive at times, but he was not going to hurt anyone. He was a partner, a fellow hero in training. Kaminari shouldn't be afraid.

Why was he afraid..?

Momo frowned, staring at Kaminari with anger and concern. She tilted her head, shifting her heavy gaze to Killua's calm expression and back to Kaminari's shaky form. Something must have clicked, for her face softened, her expressive eyes already communicating her wish: to be more sensitive.

Killua looked at Momo for five long seconds, unblinking.

She held his stare.

Killua's shoulders drooped.

"You know," He started, catching Kaminari's attention, "If the two of you fought, the smoke villain's chances of winning would be very slim." Despite his stilted tone, he seemed sincere. Midoriya could not be sure. It seemed very rare for Killua to show genuine emotions even when talking to Momo, and even harder to tell if he was being honest when he spoke to any of his other classmates.

Kaminari sputtered, conveying his disbelief.

It looked like he took Killua's words for a lie.

Killua raised an eyebrow. "What? Your power is electricity. If you use it right, there is no way you'll lose to a floating hunk of metal. A strong zap should be enough to knock him down." Kaminari was very still, listening with vague interest. "Just ask Momo to create a strong electricity conductor and get the idiot monologuing, that should give you enough time to hit him."

Kaminari blinked, seeing some semblance of logic to Killua's words. It made him noticeably less tense, but still uncomfortable.

He looked like he wanted to ask something, but his voice was abruptly cut off by the sound of doors exploding inwards. Midoriya tensed up, looking towards the USJ entrance and feeling an immediate sense of hope and happiness consume his soul as soon as the dust settled down.

There, in all his glory, stood his idol. The hero of heroes! All Might!

The sheer power of his presence silenced the entire, facility. Kaminari lost his words, stumped by awe. Izuku started crying in happiness and admiration, Sero and Momo smiled a bit, eyes shining with hope. Killua was the only one that wasn't completely captivated by the hero's arrival, simply sparing the iconic blue, yellow and red uniform of justice an analytical look and shifting his full attention to his classmates' reaction. He did that thing where you can practically hear his brain gaining new data.

Midoriya didn't mind. His classmate's constant underreactions and mysteries may be alluring, a great puzzle to crack, but All Might will always be the one under Midoriya's spotlight. Stealing all the attention.

Each of All Might's iconic words brought a force strong enough to flood the student's hearts with a sense of security.

Everything was alright now because he was here.

All Might jumped on the villains with anger and determination, disappearing in a flash and dropping right in the center of the chaos. Ripping something from the villain's face. Midoriya squinted his eyes, noticing it was one of the creepy villain hands.

Surrounded by all the villains he saw two figures, despite the distance, he recognizes Tsuyu's cute green costume and Iida's awesome Ingenium themed uniform. They looked shocked but, thankfully, unharmed.

All Might lifted something from the ground. Something black and red, human-shaped and familiar-

Aizawa-sensei!

Midoriya gasped at the thick waterfall of blood running down his teacher's face.

"Also alive," Killua stated, reassuring the nearby students.

Midoriya nodded numbly, watching his idol pass Aizawa-sensei's unconscious form over to Iida and Tsuyu. Both students cradled their teacher with care, carrying him away from the battleground.

Even with Killua's assurances easing his worry, Midoriya couldn't stand idly by, his instincts made him want to help, he needed to help. Before he knew it, his legs were already moving, approaching his injured teacher. Momo was too distracted to notice his escapade and Killua just watched him go by, curious but not bothered.

Midoriya skipped some stairs, breathing fast as he reached Iida and Tsuyu. His gaze swept over Aizawa-sensei's broken and bleeding visage, taking in the damage. "Let me help!"

Tsuyu let Midoriya's steady hands support the right side of Aizawa shoulder. Iida lowered himself to make Aizawa's left side match Midoriya's height. And so they walked.

A strong gust of wind blew on his face, shaking the pebbles of dirt on the ground and forcing the students to stop, shielding Aizawa from the force.

Midoriya froze, looking for the source and not surprised to see All Might punch the living shit out of a huge monster. The monster's muscular body convulsed at each punch, creating a loud sound of impact but no damage. This monster, 'Nomu', acted like a mindless zombie, no survival instincts, no intelligence, just brute strength and an amazing shock absorption defense.

After All Might listened to the villain's monologue about the Nomu's super defense, he changed tactics, deciding to stop throwing fast punches and instead grabbed the monster by it's waist, attempting to bury the abomination's head in the ground.

The portal came out of nowhere, sucking in half of the Nomu and teleporting the beast directly under All Might's back. With no defenses in the way, the Nomu's long fingers pierced All Might's injured abdomen, drawing blood.

Iida's body went rigid, as did Midoriya's.

The smoke villain raised from the ground, his body still slightly bent, yellow eyes calmer, perpetually full of malice.

Midoriya felt his heart pound in his chest, with each drop of blood sliding down the Nomu's claws, filling Midoriya with pure panic.

When they had met, All Might had looked him in the eye and let him know that his hero's smile had also served to hide the fear within himself.

With grave injuries, scared students and a definite, but unspoken time limit looming over his head, All Might did not smile.

He was afraid. He needed help.

Midoriya tightened his grip on Aizawa's shirt, feeling the blood, sticking thickly to his fingers, but forcing himself to not get sick. "Tsuyu." He was surprised by how steady his voice sounded. "Switch with me."

Tsuyu hesitantly shifted places with him. As soon as his fingers left the sticky fabric he sprinted towards his injured mentor, desperate to save him

"Midoriya-kun! What do you think you're doing?!" Iida screamed, his loud voice nothing more than background static. "Midoriya, don't!"

'No! All Might!' Midoriya thought. 'There's still a ton of things I want you to teach me!'

Memories flashed through his head, stealing his breath and forcing his legs to run faster. Go faster. Faster! He was almost there, just a bit more and he could he-

A mass of black smoke filled his vision, the painfully familiar portal far too close to his face. He couldn't dodge. He couldn't dodge!

An explosion dissolved the portal, cold black smoke being overtaken by scalding grey.

"Move! You're in the way, Deku!"

Ice covered the ground, going straight to the Nomu and freezing him. All Might was free. Bakugou had the smoke man trapped.

"That was close," Iida said in the background, voice full of relief.

creak

creak

Midoriya's eyes widened at the strange noise, watching in horror as the monster got out of the portal, abandoning the limbs covered in ice and limping a few steps, it started producing some incomprehensible noises before it's muscles twitched, fastly regenerating what was lost. In a matter of seconds, it back up, ready to destroy.

"What?" All Might yelled, "Wasn't his quirk shook absorption?"

"I didn't say that was all he had," the hand villain said, the implication of his words sending a chill down everyone spines. "This is his super regeneration. He's been modified to take you at your 100%."

The monster howled, intimidating Midoriya. T-Two quirks...?

Was that even possible...?

"First we got to get our gate back," the hand villain said, "Go, Nomu."

The monster ran in Kacchan's direction, immediately obeying it's master. Midoriya felt his heart drop. It was fast! Too fast! Even Kacchan wouldn't be able to dodge!

A faint breeze hit his side, no dust spreading in the air.

Something heavy dropped by his side.

"Honestly," A soft voice said, scaring the hell out of Midoriya. He jumped, his wide eyes meeting calm blue ones. "You're not on their level."

When did he...?

"It would be better to not attack," Killua added, looking at all the kids with something close to indifference. "These villains may be amateurs but they won't spare you."

Todoroki and Kacchan froze, spooked by his sudden presence. Midoriya half expected Kacchan to explode in anger but he only slapped Killua's hand away from his hero uniform, trembling ever so slightly.

"You!" The smoke villain, Kurogiri, hissed, staring at Killua with anger and a healthy dose of unease. He was smart enough to not attack.

The hand guy also focused on Killua, startled and angry. "Who?"

Kurogiri concisely informed Hand Guy on what Killua was capable of.

"Keep them safe, young Zoldyck!" All Might smiled at the information. If he was surprised by the boy's appearance, he sure didn't show it, too busy hiding his fatigue and preparing his muscles for another fight. "I'll take it from here"

Killua nodded, immediately facing Midoriya. "Don't do anything stupid," He warned, eyes alert and posture relaxed. "Momo and Iida are worried about you."

Momo and Iida? He sent a quick look to his worried friend. There was a helmet in his suit, but he did not have to see his expression to notice his tense posture. He felt bad, but he couldn't just leave his mentor like this!

All Might was bleeding and his time was almost up! No one else knew about his hero's handicap!

"Brat!" Hand Guy hissed, annoyed at being completely ignored. "I will show this kid who's really the best!" Killua smiled condescendingly in response, which did not go over well with the hand villain. "Kurogiri, Nomu, you two take care of All Might." The smoke villain looked visibly ruffled by this, but he kept quiet.

All Might puffed out his chest, clenching his fists.

"Shigaraki, do not underestimate the pale one," Kurogiri advised, his smoke unconsciously receding closer to his bent metal body.

"Yeah, yeah," the hand guy, Shigaraki, said. Shigaraki took a step forward. Killua mimicked the action, calm and confident, keeping a close eye on the villain's hands. Maybe they should let the boy protect everyone, but no one, not even Midoriya, liked the idea of being protected by a fellow classmate.

Plus All Might was here.

The strongest man in the world was here and he was fighting to protect.

That changed everything.

Worried about his students' safety, the hero went all out on the Nomu, his raw strength mesmerizing.

An exchange of fast blows send waves after waves of wind right at Midoriya's face, he could barely watch what was happening, and after a while, the monster was sent to the stars.

Midoriya was still staring at the giant hole in the USJ dome when an explosion of footsteps and flashy colors invaded the place. With whips, guns, speakers and long coats.

The pro heroes had arrived.

Everything from then on out quickly scaled for the better.

Shigaraki yelled in rage, looking positively offended by the newcomers. He cursed and whined loudly about cheaters, having to be shot twice before Kurogiri covered him, sucking the bullets with his portals and narrowing his misty yellow eyes, keeping eye contact with both All Might and Killua before fading into nothing.

A beat of silence passed before Midoriya's worry came back full force, his body already sprinting toward his Mentor before he even had time to think.

He felt Killua's eyes on him, but didn't hear any footsteps following his own hasty ones.

The dust settled down and All Might give him a thumbs up, slowly deflating but keeping a firm smile. Midoriya returned the smile, feeling his eyes water.

Everything was okay now.

.

After the cops and ambulances arrived, the professional heroes made sure to check on everyone's mental and physical state.

No student received any major injuries, only getting superficial scrapes and cuts that Recovery Girl could easily take care of. Curiously enough, Aoyama seemed to be the one that took the most damage. Midnight said he's currently in Recovery Girl's office, unconscious. He was running as fast as he could, overworking his laser quirk to go even faster and yelling for help, giving shaky explanations while curled up with an intense stomach ache and promptly blacking out.

Midoriya frowned at the new information, promising himself to pay Aoyama a visit in the hospital wing to thank him personally. If the heroes had arrived much later, All Might would have been unable to continue fighting.

Midoriya looked around after finishing his checkup, noticing how everyone was now walking close to the groups they got teleported with. Tsuyu and Iida were speaking to the medic that took Aizawa away. Ashido, Kouda, and Jirou were talking quietly, still shaken by the recent events. Shouto was alone, Bakugou was alone too, slowly dragging himself to the bus, away from all the commotion. Momo was staring intensely at an anxious Kaminari, and Shouji was quietly walking behind a chirpy Hagakure and a tired Ojirou, Kirishima was gushing about something to Tokoyami, Sero was getting his leg bandaged and Killua was still talking to one of the heroes, bristling at whatever Midnight was asking him.

He wasn't sure if he should join Tsuyu and Iida, they seemed busy, and at this point, he wouldn't mind laying down and taking a breath from all this action.

"Yo, Midoriya," Killua said, getting out of the longest check up in the whole class. He looked done with the day, pointedly not staring at the amused hero he left behind.

"H-hello Zoldyck-san!" Midoriya said, letting his curiosity loose. "You took a w-while to finish. D-did something happen?"

"Gon happened," He sounded unimpressed despite his annoyance.

"Gon?"

Hadn't he heard that name before...?

Midoriya frowned. He was sure he had heard it, but where?

"My stupid friend," Killua let out an exaggerated sigh, heavy with annoyance. "Honestly, it hasn't even been one week and I already got another mess to clean."

His words were harsh, but he had a sparkle in his eyes. It was the most alive Killua had ever seemed in Midoriya's presence.

Killua looked over Midoriya's shoulder, the light in his eyes remaining.

Kirishima and a reluctant Tokoyami were approaching them. Judging by their chattering, which consisted of Kirishima exclaiming about how manly Tokoyami was in the Downpour Zone and the bird boy giving short cryptic comments in response, they had some quality bonding time over destroying villains.

"Yo, Zoldyck!" Kirishima chirped, friendly as always. Tokoyami just nodded in silent acknowledge, Dark Shadow peeking underneath his black hero uniform. "You were so manly back there!" His smile widened, displaying sharp teeth. "It was all speed and power, I couldn't even see you, dude!"

"That's the idea," he said, giving them a small smirk.

"Darkness shall stray their sight," Tokoyami replied.

Midoriya didn't quite understand what he meant by that, but judging by his tone of voice, he approved of Killua's tactic.

Kirishima laughed in good nature after seeing everyone's bemused faces. "Not gonna lie, I am still trying to understand him too."

Tokoyami huffed at this, but he didn't seem particularly offended.

Midoriya smiled awkwardly at the boy's loud enthusiasm, sparing Dark Shadow a curious glance as soon as he heard the mass of darkness imitating it's master's huff. Now that he got a clear view of Tokoyami's quirk, he could see the bird creature's body of constantly shifting darkness, creating an otherworldly texture that imitated human emotions.

Midoriya couldn't help but ask, "Is it alive?"

Tokoyami nodded in a solemn manner, contrasting greatly with the offended "Rude!" that Dark Shadow squawked out.

Midoriya felt his cheeks heat up, not expecting a verbal answer from the shadow. "I meant no o-offense!" He looked away, unsure how to interact with Dark Shadow, but still very curious. "I was just wondering how you can function, your texture is so cool but it's too solid to be shadows, I don't know how you can have a voice of your own or-"

"Dude," Kirishima laughed. "You're mumbling."

"Again," Killua added.

Midoriya shrunk into himself, embarrassed. He kept being painfully awkward, all these amazing hero students must think he's a barely functioning mess. "Sorry!"

Killua rolled his eyes, "You brought up a valid point, stop apologizing every five seconds."

"S-sorr-" Midoriya himself stopped midway, horrified of his mistake.

Kirishima grinned as Killua snorted in amusement and shook his head "Hey Tokoyami," he said, pointing at Dark Shadow. "Can I touch him?"

"No!" The shadow said, inching away. Tokoyami closed his eyes, "...I wouldn't recommend it."

Killua eyed the shadow innocently, way too innocently. There was no way he wasn't prepared to ignore his classmate advice and go forward anyway. As if sensing the potential disaster unfolding, Momo approached their little group, visibly troubled.

"Killua-kun," Momo called. "Kaminari was looking for you."

Killua raised an eyebrow, putting his hands inside his pockets. "Really..?" He sounded skeptical "I thought for sure I accidentally traumatized him yesterday."

Midoriya didn't understand how someone could accidentally do such a thing. Tokoyami and Kirishima shared a look, probably going along similar lines of thought.

"Don't be like this," she said disapprovingly at his dark sense of humor. "I think he wants to apologize."

He glanced to where the blond student was anxiously waving, keeping his golden eyes locked on his, for once. Killua tilted his head, considering Momo's words but not believing her.

"Okay," he eventually decided. "I'll see what he wants."
