AN: I don't own My hero academia

Liar

A pair of operatives marched side by side along an empty hallway. Their footsteps echoed along the hard floor. One was a woman with a stern expression. She wore military-like gear with cargo pants, a turtleneck tank top, and a pair of hard boots. Her long blue and pink hair was tied in a high ponytail. The other was a man similar in age. Pale blonde hard hidden under a fedora. He wore an oversized black trench coat with a long train and a pair of matching leather shoes. They squeaked with every step. Unlike the woman, the man had a never-ending smile on his face. The two walked in relative quiet until the woman spoke up.

"This is crazy!" She yelled, and she swirled her body to block the other's path. "Can't you try and pick anyone else."

"Like someone not on the kill list?"

"Exactly!"

The man laughed all too kindly. "No, I made up my mind." His smiling eyes softened sternly as he glared the woman down. "We had a deal and I'm not going to let the commission kill him."

"But why," the woman argued back. "He's on that list for a reason. He wasn't just trained to be a puppet hero. He was also trained to kill."

"And you aren't?"

The women stopped talking while taking a step back. Her purple eyes glared at the other hurt. "That's a low blow."

"I know," he simply said, fulling knowing his words hurt her deeply. "Then again, if you get to live why shouldn't he?"

"I'm not the one brainwashed into a monster," the woman argued back with stronger furry in her tone. "The files said he's extremely temperamental. They can turn nearly anything they see into a weapon. That's why..."

"They locked him up in a dark room and forced a weighted mask on his face to take his quirk away." The man finished for her. "I'm fully aware of the danger, my friend. If this is the last thing I do, the commission can laugh at my death. And I'll die knowing that I tried. I see it as a win, win either way." He continued walking fully knowing the path he chose could kill him. Yet he didn't care. He wanted to see that man smile. A man who couldn't even tell him what his favourite colour was. Who looked confused when he asked him for coffee. Whose eyes were so bright and so dull at the same time. He would live with such regret if he didn't at least try. Suddenly, he felt a pair of hands clenched behind him. A face was planted firmly in his spine.

"Please don't do this," she begged while tightening her grip. "I don't know if I can stay sane without you here."

Swiftly, the man turned around and embraced the woman warmly. She easily accepted the hug, hoping it was a sign she won. It wasn't. "I'm sorry,'" he whispered in her ear before chopping the back of her neck knocking her out temporarily. Her body slumped in his arms, and he carefully dragged his friend to a corner. One where she won't get hurt as well as be hard to spot. He rather not let anyone else interrupt him. Then he pocketed a key card from her and went on his way.

Eventually, he reached his destination. In front of him was a mechanical door. Warning labels were plastered all over it. It didn't scare him. Without hesitation, he swiped the card down. The gears twisted and turned till the door lifted itself up. Beyond it was a man. Chained to the far back of the walls, his head hanged from his shoulders, as his curly long black navy hair pooled at his knees.

Once the door opened the man lazily lift his head. A pair of deep blue eyes stared back at him annoyed but curiosity.

"Hello in there," He greeted as brightly as he could. "Do you remember me?"

The other said nothing. Only stared with his deep blue eyes.

Cautiously, the man walked in. The light of escape behind him grew ever smaller as he walked into the shadows. He then crouched down to the chained man's level. "It's me, coffee guy. I asked what your favourite colour was. You saved me from a construction beam," he tried to explain but didn't get a word back. He supposed the story did sound a little odd. "Do you have an answer for me now?"

Yet again the response was nothing.

Combing his ash-blonde locks, he hummed thinking of ways he could get some type of reaction. "I know! What do you call a pig who does karate?"

"…"

"A pork chop!" He yelled out the answer with a giggle while drumming on some invisible drums.

The other did not look amused. More confused.

Tough crowd. The man hanged his head defeated. So, he tried something else. Silly faces! Fish lips, pig nose, tongue out. Anything he could think of with a pairing the most ridiculous noises his body was capable of. He did this for a good minute and looked completely stupid.

'You're strange.' He heard echoed in his head

The man dropped the faces and smiled. "You finally responded to me." He then held out a hand. "I don't think I full introduced myself last time. My name is Sai Darewell."

The other stared at the hand. Not entirely sure what to make of it.

The look in their eyes. That touch of curiosity. He wanted to see more of it. That's why… "If you have nowhere to go. You can come with me," he wanted to reach out. Take on the challenge without regret. He wanted to see this man smile. Even if it was for a second.

Eventually, the other took his hand.

It happened in a flash. All Might's body glowed with a blue hue before floating up and was flung out the window. Shattered shards of glass chipped onto the counters and floors. Just another thing to add to the growing mess. In the centre of it was Arata. His eyes glowed brightly and were highlighted with tears. There was only pure anger across his face as his eyes aimed out the broken window. Then his body began to glow and levitated. Bringing with him an elongated, thin, black back that housed his weapons of choice. He wasn't done yet.

"Arata, stop!" Enji yelled and pounced on the man. He felt himself float up with him, but it was enough to weigh them in place. "You need to calm down."

"Shut up!" Arata shrieked. Any sense his tone was gone. It wasn't long until Enji started to glow and was ripped away. Violently, Enji was tossed around in a whirlwind to a wall. It crumbled and cracked to fit their shape. "Don't try to stop me!" Arata yelled one last time before flying off to do who knows what.

Well, Enji could harbour a guess. He wasn't dumb. Once you know all the pieces and put them together the picture became clear as to what Arata wanted to do. Depending on the severity, he might need to get his hero costume. It's because of that reason he had to do whatever he could to prevent the man from doing something stupid. Both luckily and unluckily for him, they're facing off against arguably the strongest hero in Japan. He knew All Might could hold his own if things got rough. Arata on the other hand.

Another fact about the man came to mind. Precisely, about their quirk's critical weakness. It made his blood ran cold. His mind raced with possibilities as his legs took him down the hall. He had to act fast and defused the situation before anything disastrous happen. Once at the door, he slapped a pair of random shoes on. Any will do. The man was running on pure adrenaline now while panicked thoughts ran around his mind. He had to stop the escalation. However, the second his hand reached the door handle he heard a voice behind him.

"Dad, what happened?" Touya came running up to him along with the other two children. All of them wore worried faces. While they weren't completely sure what happened, but the violent ruckus was enough to set them on edge.

"Never you mind. Just stay where you are all of you. I'll deal with this." Enji ordered.

"But dad!"

"I mean it!" He yelled louder. While he wasn't completely sure what was happening between Arata and All Might, he knew he didn't want the kids anywhere near it. The last thing he wanted was for any of them to get hurt. "This isn't something children should get involve with." He gave the children one final cold stone glare to keep them in place. Then rushed out the door slamming the shut behind him.

His cold stone glare seemed to have worked. All three children stayed in their place frozen, but it wouldn't last forever. Touya hands started clenching. Their core heated as steam smoked out from his finger gaps. It was frustrating. Being told to say put as if they couldn't do anything to help. Like they were useless in this situation. Nothing was the best they could do. Yeah, that wasn't going to happen.

A fire lit in the boy's stomach as he glared at the place his father was moments ago. Without any further hesitation, he disobeyed his father's words and raced to the door.

"Touya! Stop!" His little brother called out to him. "Father said."

"Forget what dad said." The older Todoroki snapped back before his little brother could parrot their father's words. "Do you really think I'll stay here and do nothing? Who knows what going on out there? I doubt dad can do it alone." Izuku opened his mouth, clearly ready to fight back, but Touya wasn't having it. "Oh, shut up," he cruelly hissed. Shocking his little brother's mouth to shut. He then marched forward to him. His dominating aura made the child retreat a couple of steps while his body turtled in on itself. It's been a long time since he has seen his older brother's gaze of rage like this. "You're always such a goody-two-shoes. Listening to dad's every word. Agreeing with everything. Don't you have your own opinions? Or Are you just going to follow his words like law forever?"

Of course, Izuku said nothing. Like a good little boy, he stayed quiet.

Touya clicked his tongue at his younger brother's silence. "Stay back here all you want. I'm going." He reached out to the door again. And again, he felt someone pulled him back. It was frustrating. He was ready to punch them until he realised the one holding him back was Tenko.

The smaller boy's lips were quivering but his eyes were determined. "I'm coming too," He claimed. He wasn't sure what he could do but if there was anything he wanted to try. Besides he couldn't help but feel this was partly his fault. Touya nodded back to him, and they both left the house together.

That left Izuku all alone. Frozen in the entryway. Like a good little boy.

Meanwhile…

An enraged Arata chased after a very confused All Might. Four blades tailed close behind the psychic quirk user. They threatened to skewer the hero, but All Might managed to dodge them even if it was just barely with a few cuts in his clothing. The two other of them tussled in the air for quite some time exchanging glares, grunts, and a couple of fists. Eventually, they landed unceremoniously into the nearby forest.

Once back on solid ground the two went for each other. Well, more so Arata, who fiercely slashing away with his blades in random directions. It was wild and uncoordinated. It made them easy to doge. For the most part. Dodging four blades at once isn't an easy task. Unless you're the number 1 hero who happened to have not only ridiculous strength but speed as well.

All Might dodge those slashes like the pro he was. Bending backwards and dashing to the side, all in a nick of time. It wasn't long until he reached the caster and punched them in the stomach. Nothing too strong. A mere love tapped that ended with some blood coughing. The most impressive thing was that his opponent was still standing. Their eyes glowed bright and soon All Might found himself swallowed in blue light. A force made his limbs constrict into his body in awkward positions. He then found himself being thrown around like some rag doll.

Dirt and leaves kicked off through the ground as man-size indents left their marks in the mud. Arata wasn't thinking straight or maybe he was. There was something chaotically satisficing treating the number 1 hero like a rag doll. He could almost call it fun. Was it so easy? No. It never will be. A shock suddenly ran through his brain. Like a knife, it stabbed his brain violently. Shaking his body to his core. Arata fell to his knees. It's been a long time since he felt this type of pain. Since it's been a long time some had been able to bake out his quirk at full force. It shouldn't have been surprising knowing who he chose to pick a fight with.

Rising through the dusk All Might stood seemly unharmed. Barely, a scratch on him aside from the varies of marks on his white T-shirt and cargo pants. Still, after the beating he took it's amazing how he was still standing so proudly. Then again, he wasn't number one for nothing. In a blink of an eye, he crouched down to a running start then dashed in for his own assault. He threw a hand and it collided with his opponent's face. Yet his opponent did have enough time to move just enough so the impact wouldn't, unfortunately, be a K.O

Arata's eyes glow as his sword started moving around again. Yet he couldn't land a single strike on the hero. They, on the other hand, landed several. What was worst was that he could tell the hero was going easy on him. They had many chanced to land a fatal blow. If this was easy mode, he couldn't even begin to imagine what hard mode was like. In a panic, Arata went on the defensive, bringing his sword together to act as a shield against the hero combo of fists. It proved to be useless. The swords cracked under the pressure. It wasn't long until the mighty hero's first smashed through them. Shattering them to pieces. With the yelp, Arata was blown away with them. His body was thrown against a nearby tree. He could hear his spine cracking from the collision. The pain causes his body to shut now for a second. It slumped over the forest floor. No matter how hard he tried to move his limbs wouldn't respond. This is the power of the number one hero.

Barely phased, All Might marched towards the fallen man that was so eager to fight him. He admitted they put up a good one. Their quirk was an impressive one but wasn't enough to beat him. "It's over. No matter how you look at it. I can overpower you," he proclaimed with a heated growl from his fallen opponent. "Your weapons are destroyed. You can barely stand. How about we talk like civil men. I won't even press charges."

If he could, Arata would be laughing. This man thought just because he was weapon less, and his body could barely move physically, he thought this was over? Far from it. Although, it has been a while. He was most likely out of practice. Not to mention how dangerous it would be, but he didn't care. The rage and hatred in his heart blinded any sense he had left. All he wanted to do was forced this eyesore of a hero to his knees. By any means necessary. "Force quirk evaluation. Have you ever heard of it?"

The sudden question confused All Might. He has heard the concept of quirk evolution. A theory which could be tied to the growing idea of quirk singularity. It was common among only the most highly trained individuals where they unlock a new stage of their quirks. Making them go to higher levels. Perhaps even unlocking new applications of their quirks or breaking their previous limits. Those who achieve such feats see to it with pride. However, that 'force' part brought a chill in his blood. Something didn't feel right about how the man said it.

"It's a gruelling process. You're forced to use your quirk over and over. Breaking your limits constantly without rest or care of any kind." The man's voice deepened with every word as his fingers clawed at the dirt. His eyes twitched as if remembering something unsightly. A horrid and chilling memory. "There were some whose bodies can't keep up. So, they die." He said so nonchalantly it was unsettling. Arata could see them vividly. Hear the too. The cries of pain. The useless begging. The cracks of whips. Heartless commands. "I've seen it so many times. How they drop like flies around you." It was then Arata's eyes began to glow once again. Only even brighter this time. His body was soon encased in the same blue glow.

Alarmed, All Might leapt back not entirely sure where this was going. The force that was swirling around his opponent told him it was no good. This doesn't seem like it will be over anytime soon.

"Yet if you survive," Arata cackled bitterly as his body rose from the ground. Levitating higher and higher. He looked down at the hero with eyes painted with a deranged expression. "You'll break through all your limitations and use the full extent of your quirk. Any natural safeguards to stop you are broken with them." Truly a deadly process that awards a double edge sword. Just because the quirk had grown to max limit doesn't mean the body would follow. But that fact didn't matter now. His mind honed on one thing and one thing only. This so-called number 1 hero. "As far as I'm concern everything around me is a weapon."

A chill ran down the hero's spine as the echoing of rustling leaves boomed around him. It was unnatural. How they crinkled in unison. Even more unnatural when hundreds of them glowed blue. Curled into themselves to a sharp drill tip. It wasn't long until they fired in all directions. Some of them missed him. Others grazed him. Few drilled themselves into his muscles. It was surprisingly painful but nothing he couldn't handle. More like a bunch of stinging, deep paper cuts. Annoying but nothing in the end. With a battle like a roar, All Might spun around changing the wind current around him. It knocked all the weaponised leaves out of place as well as scattered drops of blood around him. He dispersed them enough to back an opening and he took it. Changing directly at the floating caster with a battle cry.

The hero bent his legs and launched himself up high enough to grab his opponents on the shoulder. The man weight amounted to nothing as the hero wrestled them to their back mid-air. They were still floating but the weight of the hero was enough to bring them both down gradually. As they fell All Might yelled, "why are you so angry with me!"

To him none of this made sense. He only meant this stranger today, yet it was obvious to anyone that they held such animosity towards him. It matched that of villains' hatred, yet he doesn't think this man was any villain he put behind bars. Usually, they stay behind bars. The rage that burned in their eyes felt different. Mix it with that hate was…pain. A type of pain All Might couldn't quite understand.

Arata's gritted his teeth at the question. His rage only grew because of it as well as the pounding in his head. It hurt. It hurt so much. But it didn't matter. He could push through. He could keep going. The consequences were meaningless. His eyes glowed even brighter as they aimed themselves at a nearby tree branch. It glowed with his signature blue and thrust itself down at the two falling men. Like a hand come to life its finger branches wrapped themselves around the hero and violently plucked him from the caster. They then sent the hero flying as high as they could like a catapult.

Not missing the opportunity, Arata flew higher with a fist at the ready. Bring with him all his pent-up emotions. "It's because you're an eyesore." He screeched with his first punch that collided with the hero's cheek. "An idiot." He continued while punching the hero's other cheek. "But most of all." It wasn't long until the disoriented hero was glowing blue again. This time with a much stronger force griping on him than the last. Before the hero had a chance to break free and recovered, Arata forced him to spin around before thrusting them back to the ground. His raging voice only got louder and violent. "You're a liar!"

Crash!

Izuku found himself alone in his home. Wondering the empty hallways. There was no point for him to go. In disobeying. After all, what could he do? He was just a child that didn't know better. A weak, quirkless child with no power. He was useless. The type to only get in the way. So, he'll stay behind like a good little boy. His father didn't want him hurt after all. So, he should stay out of trouble. The others could handle whatever was going on without him. They were stronger. Capable. They even had the number 1 hero there. And All Might. That guy too. He can't do anything.

But still.

The child wandered aimlessly until he reached the dining room. At least what little remained in it. Paintings on the walls had fallen. Chairs have been broken. Glass decorated the floor, and the table was flipped upside down. A good two-inch crack ran down its side. It was a mess in every meaning of the word. Form it Izuku clearly deduced there was a fight. The cracks in the table told him this was not a one-sided fight. The last the saw of the adult men after his father shooed them out All Might was sitting there. Knowing their placement and likely action, All Might was the one who made those cracks and flipped the table. The symbol of peace must have been ticked off badly to grant such a reaction.

The fallen paintings and misplaced objects were clearly Arata's doing. The man's quirk tended to flare erratically when he was emotional. It was rare but Izuku has seen it a couple of times. Like when he kept pestering him about Sai. The man grew so uncharacteristically angry that he pushed the child down with his quirk once. It was all an accident, and he didn't get hurt too badly. His teacher's eyes would glow and any objects in his field of view would glow with them. Since the only paintings and objects affected were on the other side of the table, the focus of his anger must have been sitting in front of him. The only person that could be was All Might.

From these facts alone the child could easily tell neither of them liked each other. They pretty much started to be at odds the second they saw each other. Then it somehow escalated to a full-blown fight. That's why the dining room was in ruin and there was a screaming match. If those two are fighting, then there really wasn't any reason for him to go. What could he do? Nothing.

But couldn't there be something?

In the corner of his eye, he spotted something glimmering by a stream of light. It was scattered among the glass shards. He thought it was a piece of glass but that couldn't be right. Its glimmer had an oddly golden tint. On closer inspection, he spotted Arata's locket between the shards. He carefully picked it up, avoiding the sharp shards around it. They never took this off, meaning the chain must have snapped apart during the struggle. The boy's little scarred hands played with its outer shell. The locket's casting was made of cold metal, but it felt oddly warm. It was a kind warmth. The loving type.

While his fingers tranced around its fame it suddenly clicked open. It revealed a touching image of two men. One held the other bride style. Their hair was long and curled with a navy black hue. It contrasted nicely with their white suit with light blue accents. The expression he wore was soft while his blue eyes held such love. They were looking at the man in their arm's. A far more playful gentleman with one of their legs kicked up and arms out in celebration. They too wore a suit, but it was black with dark green accents. It matched well with their ash blonde hair. They winked at the camera with an eye that matched his own.

From the minor descriptions he remembered, Izuku could easily recognise the blonde man to be Sai. Arata's husband. It was the first time seeing them, but they were exactly how he imagined. That meant they had to be his teacher, but he looked different. Besides the outer appearance, he looked happier. The smile that the boy used to see felt fake and genuine at the same time. As if he enjoyed his time yet hid his true feeling deep down. But the smile in this picture. It felt 100% genuine. The boy wondered where that smile had gone?

Soon Izuku placed all the pieces together. This picture. His teacher's odd behaviour in recent weeks and how he snapped so suddenly. It didn't make a pretty picture. He clenched the locket in his hands closing it shut. He then looked out at the broken window in thought.

There had to be something he could do.

AN: well…this was half an event. It became too long for my format, so I split it. good news is that might mean the next one might be a little early since its half done. No promises. Also, the lady from the first scene flashback should be familiar to you manga readers. She is not an OC, but she might be a character I may use in the future. Depending on how far I'll go. Also, I think this is the first time I showed Sai outside of Arata talking about him and his memories.

So extra context since I don't know how deep I'll explain it in story. Arata was always meant to die since the hero safety commission saw him as a lost cause. Too dangerous and unpredictable to be rehabilitated. That's when Sai came in and pretty much blackmailed them into giving him a chance to rehabilitate Arata. It's only mentioned briefly but Sai did work for the hero association. So, he has a lot of their dirty laundry to use against them. He was also very well liked amongst other agents, staff members and even those outside who worked in law enforcement. So, they couldn't get rid of him easily without at least one person sticking their nose in and causing more problems down the line. It was much easier for them to let him do it. Then hope he'll die tying to get rid of him as a threat without getting their hand dirty. Also, they'll have a reason to label Arata as a villain and kill him justly. Or Sai miraculously turns Arata into a model citizen and everyone walks away form this deal happy. So, the commission had nothing to lose but one of their agents since Sai quit working for them to be Arata's full on caretaker.

guest nr 386 – I first like to say I don't hate All Might. While he's not my favourite by any means, I respect what his character means for the overall story. You can't deny the man works hard to maintain his vision of society. That and it's confirmed in the vigilante's series and a bit in the main that he has trouble doing paperwork. Nighteye was the one who deals with that. So, some things may have gone unnoticed. Still if he just slowed down. Even a bit maybe this wouldn't happen. Better now since he can afford to slow down since the hero industry is booming. Let someone else take the spotlight for simple crimes.

now when it comes to who the better parent with what has been presented Arata is better by a little. I say little because he is not exactly stable. Losing Sai really messed with his life. Quitting his old job, letting his home go to ruin, miskicking his lost love to feel even a little closer to him, etc. The fact that his previous live before him was not at all clean just adds to the instability. The thing that edges him out is the fact he has the Todorokis and Tenko already likes him. It is still questionable if he is up to the task of being a single parent.

Anyway, that's all next is the climax of this fight.
