MHA Universe, Earth, Japan, Yokohama.
"What happened to the Nomu facility?" Toshinori asked, stopping Rumi from jumping into the fight between Tatsuo, Alfonzo, and All for One. "More importantly, what happened to... all of this?"
Huffing in annoyance, Rumi stopped cracking her knuckles. Then, she gave Toshinori a quick rundown of what happened, repeating Akatsuki's and Sakura's explanation. When Rumi's story finished, Toshinori turned towards the ongoing battle. And when she saw All for One's face, his eyebrows shot up in shock and anger.
"All for One!" Toshinori shouted, wrath dripping from his roar.
Hearing that familiar voice, All for One snuck a glance in its direction. And when he saw Toshinori, nemesis, he could not help sneering before opening his mouth to mock the Symbol of Piece.
"So, you're--- Urgh!" All for One began to say.
*Bang!*
*Splatter!*
However, before All for One could even get started, Tatsuo, angered that he was being ignored, slammed an uppercut into All for One's open jaw, snapping his mouth shut and causing him to bite through his tongue.
"You're fighting me, Asshole!" Tatsuo shouted angrily. "Unless you plan on telling me who the fuck is targeting me, don't you dare look away! Otherwise, I'm cutting off that little thing between your fucking legs!"
Despite his pain tolerance, which allowed him to merely grunt at having his chest impaled more than once, All for One found himself shivering at Tatsuo's threat. Clearly, no matter how strong a man is, that kind of pain was not something they could just shrug off. Even the thought of experiencing such pain was more than most men could bear.
"Fuckin' cold blooded." Alfonzo said while involuntarily squeezing his thighs together. "But honestly, I'd rather not have to see that thing lying on the pavement. So, let's make sure it never gets to that point. [Gravity Ball]."
Alfonzo then created an electromagnetic field in his hand. And the density of the field caused the gravity around it to fluctuate before it increased dramatically a moment later.
Meanwhile, Akatsuki, Sakura, Toshinori, and Rumi were dumbfounded by the amount of anger they heard from Tatsuo's voice. Because they had not been present when All for One took out the vial and mentioned that he had been told to eliminate Tatsuo, they had no idea what set him off, either. As a result, neither Toshinori nor Rumi jumped into the fight immediately.
"That's the furthest thing away from heroic I've heard you say all afternoon, Soramoto-Kun." All for One said after his tongue regenerated. "Are you really aiming to be a Hero? It sounds like you'd fit in better with my League of Villains. Unfortunately, because I have to kill you, that won't be possible."
Tatsuo only snorted at All for One's attempt to rile him up. Despite his anger and his dragon side doing its best to influence him, he was still in control, if not more aggressive than usual. So, All for One's taunt had very little effect on him.
*Bang!* *Bang!* *Bang!* *Swish!* *Swish!* *Bang!* *Bang!* *Bang!* *Swish!*
Instead, Tatsuo continued his onslaught, landing powerful blows that continuously broke bones, avoided counterattacks, and tore through All for One's defenses with his [Spatial Rends] and [Spatial Slashes].
And these clashes were happening at a speed that Akatsuki and Sakura were incapable of following. Meanwhile, Rumi, who, like Toshinori, had no issue following the action, was preparing to jump in and join the fight.
Toshinori, on the other hand, was still reeling from the fact that All for One seemed to still be at his peak, despite how badly he had been injured at the end of their last confrontation. The same confrontation that left him with many of his internal organs damaged or missing altogether.
"How is this possible?" Toshinori growled angrily as the pain he felt constantly flared up to an uncomfortable degree. "The last time I saw him, I left him for dead. There's no way he should have been able to survive that."
Shaking his head to banish those thoughts, Toshinori bent his knees. Then...
*Boom!*
... he jumped towards the ongoing battle, the force of his leap causing the already destroyed ground to crater. Meanwhile, Rumi growled at Toshinori, who she wanted to stay behind and protect Akatsuki and Sakura so that she could join the battle.
"Damn muscle head." Rumi hissed.
"Hello, Kettle." Akatsuki said while holding her hand up to her ear in a telephone gesture. "This is Mirko... I just wanted to say, you're black."
Sakura could not help giggling at Akatsuki's joke while Rumi snapped her head in Akatsuki's direction, causing the younger woman to look away.
*Chuff!* *Chuff!* *Chuff!* *Chuff!* *Chuff!* *Chuff!* *Chuff!*
However, before Rumi could bark at Akatsuki, her ears twitched at a familiar sound in the distance. Looking towards the sound, she saw a helicopter approaching the battlefield.
"Tch!" Rumi clicked her tongue in annoyance. "Of course they're here. Now there are even more people to protect. Don't they know how dangerous things are right now?"
"Huh? Who's here?" Sakura asked while looking in the same direction as Rumi. Unfortunately, her eye sight was not good enough to see the helicopter at such a distance.
"The media." Rumi said, her annoyance evident. "Someone probably saw All Might rushing this way and posted it on social media. Then, the news followed up, thinking there was some kind of scoop."
"Well, they're not wrong." Akatsuki muttered. "But I don't know if this is a good time for them to show up. Tatsuo-Kun isn't exactly at his most presentable right now."
Akatsuki, Sakura, and Rumi were not the only ones to notice the new helicopter approaching. Tatsuo, Alfonzo, Toshinori, and All for One recognized it, as well. And like Rumi, Tatsuo clicked his tongue. And surprisingly enough, it was for the same reason. Fighting All for One was already a big enough problem. Having to protect civilians while doing so would be a nightmare.
Alfonzo and Toshinori, on the other hand, were more focused on dealing with All for One, especially Toshinori, who approached the fight at high speed with his right fist cocked back and ready to deliver one of his signature [Smashes].
"[Detroit Smash]!" Toshinori shouted once he was within an arm's distance of All for One.
Yet, Toshinori never threw the punch he intended to. And the reason for that was...
"Stay the fuck out of it!" Tatsuo shouted as he threw a backhand at Toshinori. "This isn't your fight!"
"What?" Toshinori exclaimed as he dodged Tatsuo's attack. "Don't be stubborn, Young Soramoto. This is someone beyond your current capabilities. I have no doubt you could handle him in the future, but..."
"I said stay out of it!" Tatsuo shouted as he raked his claws across All for One's chest. "You have no idea what I'm capable of!"
*Splatter!*
Once again, All for One's blood splattered across the ground after one of Tatsuo's attacks. However, just like before, his [Super Regeneration Quirk] quickly mended his injuries as he stumbled backwards from the attack. And as he did so, he looked towards Toshinori with a sneer.
"He's right, Yagi." All for One said mockingly. "You don't have what it takes anymore. I can feel it, you've already passed on [One for All], haven't you? On top of that, you're still injured from the last time we met. Face it, you're out of your league."
Gritting his teeth, Toshinori knew that All for One was correct. Even so, he could not stand having to stand by while one of his students fought against his nemesis.
*Zap!*
However, before Toshinori could respond, Alfonzo, cloaked in his violet electricity, appeared behind All for One with a glowing orb in his right hand. And when Toshinori felt the aura coming from that orb, he could not help widening his eyes in surprise.
Meanwhile, Tatsuo spread his wings and soared high into the sky. At the same time, Alfonzo slammed the orb into the center of All for One's back. Then, he flashed away before All for One's [Rivet Stab] could skewer him.
"What is--- Argh~~~~~~~~!" All for One screamed before he could ask his question in full.
For the first time, despite all the damage he took from Tatsuo's onslaught, All for One screamed in pain as the orb Alfonzo slammed into his back began to put pressure on him. Having every part of his body being drawn towards a single point was more than anything the Symbol of Fear had ever experienced.
"Now's my chance!" Toshinori shouted as he once again reeled his right fist back. "This is the end for you, All for One! [United States of Smash]!"
"You're not strong enough!" All for One bellowed after seeing Toshinori trying to attack him again. "[Spring-like Limbs], [Hypertrophy], [Kinetic Booster x 4], [Strength Enhancer x 3]!"
*Boom~~~~~~~~~!*
The collision between the two fists caused a shockwave that sent all the debris surrounding Toshinori and All for One flying nearly a thousand feet in all directions. Even more impressive than that was the fact that Toshinori was sent flying as well. On top of that…
*Crack!*
"Argh~~~~~~~~~~!"
… the bones in the Symbol of Peace's arm broke in several places, causing the blond Hero to scream in agony.
"*sigh* You're so stubborn.' Alfonzo said after flashing behind Toshinori and catching him. "You're not at full strength because of everything you've been through. Why won't you just let us handle this?"
Toshinori did not respond to Alfonzo's question, only gritting his teeth with a feeling of impotent rage, causing Alfonzo to sigh once again. He then looked up before speaking again.
"Well, you're not gonna have a choice." Alfonzo said. "T is about to end this once and for all."
"Huh?" Toshinori intoned while turning his head to look at Alfonzo. He then saw that Alfonzo was looking up at the sky, causing him to turn in the same direction out of curiosity. "What are you---"
However, Toshinori could not voice the rest of his question. Because what was at the end of his line of sight was Tatsuo with his wings spread wide, arms raised high above his head with [Spatial Energy] coating his claws, and a savage expression on his face.
"Wait! What is he about to do?" Toshinori asked in a panicked tone.
"What needs to be done." Alfonzo replied in a solemn tone.
"[Spatial Rend]." Tatsuo shouted, his voice echoing over the area as he slashed his arms down towards All for One.
Following the path of Tatsuo's arms, a net of [Spatial Energy Slashes] descended towards All for One. And judging by the trajectory, those slashes would dice All for One's body from the nick down.
*Swoosh!*
An instant later, Tatsuo, his claws still coated in [Spatial Energy] reoriented himself in the air before flapping his wings and shooting down behind his [Spatial Rends].
By now, the [Gravity Ball] pinning All for One to the ground had expanded, engulfing him completely. So, the only thing he was currently capable of doing was watching the attacks that would end his life approach.
"Ha! Hahaha! Ahahahahaha!" All for One could only laugh at the end that was approaching. Even so, he could not help trying one last mind game. "It looks like you've resolved yourself to kill me, Boy! But how do you intend to get the information you seek if you do that?"
It was obvious to everyone that All for One was trying to make Tatsuo hesitate. And the reason for that was simple. Though it was slowed down by the gravity acting on his body, All for One's [Super Regeneration] was still at work.
Meaning, if he could by himself a little more time, he would be able to return to fighting shape. And once he did that, he could start planning to get away from the gravitational field. He might even be able to get Tatsuo to dispel it in his anger.
Unfortunately, All for One had no idea that Tatsuo had been trained as an assassin for years. As a result, despite his towering anger, Tatsuo would not hesitate to go for the kill. And giving his target a chance to recover was even further out of the question.
So, when Tatsuo did not slow down at all, it surprised not only All for One, as Toshinori and Rumi were both surprised by his ruthlessness, as well. While Rumi did not seem to mind Tatsuo's intent to kill, Toshinori was panicking visibly.
"Alfonzo, what are you doing?" Toshinori, shuddering at the amount of killing intent he could feel pouring out of Tatsuo, asked in a frantic tone. "You can't let him kill him."
"Why not?" Alfonzo asked bluntly. "This is better for everyone. All for One is a blight on the world."
Hearing that, Toshinori was stunned. From what he knew about Alfonzo, he was very protective of Tatsuo, despite the fact that he always teased his younger cousin. As a result, he only stared at Alfonzo blankly for a few moments.
Meanwhile, Alfonzo watched Tatsuo's descent. While doing so, he noticed that the scales on Tatsuo's body were increasing in number and covering more of his skin.
"That's not the point!" Toshinori shouted. "Once he does it, there's no going---"
*Splatter!*
Before Toshinori could finish, the [Spatial Rends] reached All for One. When they did, they diced his body below the neck into pieces.
"Argh~~~~~~~~~~!" All for One bellowed from the pain of having his body cut into so many pieces.
Seeing the gory scene, Akatsuki could not help turning away while she was hit with an intense case of nausea. Sakura, on the other hand, who had grown up in a Magus family, did not even flinch when she saw the gruesome sight.
*Boom~~~~~~~~~!*
Not even a second later, Tatsuo, with his wings folded behind him and his hands extended, slammed into the ground, his claws tearing straight through All for One's skull and brain before impacting the ground, causing severe trembling along with a large dust cloud to shoot up into the sky.
Then, before the dust even started to settle, Tatsuo, Alfonzo, Akatsuki, and Sakura knew the fight was over when an information window appeared in their fields of vision.
{[Notifications]
Objective 5 – Defeat All for One – Complete}
The [Notification] made the four otherworlders breathe sighs of relief. At the same time, with All for One put down for good, Tatsuo's anger began to fade. Though, it did not disappear completely. Even so, he slowly began to return to his human form, the scales, claws, wings, and tail receding into his body. Then, once he was back to normal, Tatsuo slowly stepped out of the dust cloud, patting dust out of his hair as he came into view.
"Damn... I overdid it." Tatsuo muttered to himself. "it's gonna be a bitch getting all this dust out of my hair."
"You're fuckin' right it is." Alfonzo replied as he, while still carrying Toshinori, said as he landed next to Tatsuo. "And you better clean the bathroom real good after you're done washing that shit out later."
"Whatever." Tatsuo replied while rolling his eyes.
"Don't you take that tone with me, young man." Alfonzo said in a playfully stern tone. "As long as you live under my roof, you'll live by my rules. Do I make myself clear?"
Once again, Tatsuo rolled his eyes at Alfonzo's antics. Meanwhile, Toshinori could only stare at the two dumbfoundedly. Thinking this was Tatsuo's first time taking a life, especially since he was only fifteen years old, he could not understand how Alfonzo and Tatsuo could joke around like they were.
*Chuff!* *Chuff!* *Chuff!* *Chuff!* *Chuff!* *Chuff!*
Unfortunately, Toshinori could not bring it up again with the sound of the helicopters approaching. Instead, he had to coordinate with Alfonzo and Rumi to get their stories straight about what happened here. Because under no circumstances could they mention that All for One had been here. Otherwise, that would just cause mass panic.
