Bakugo charged forward with hus explosions, arriving before All Might before holding his hands out, creating a sphere of light between his hands that exploded into a large scale flash.
"Ho?" All Might hummed as the light engulfed him. As the light disappeared, All Might quickly noticed that Izuku and Sukuna were gone.
From his sides, Izuku and Sukuna charged towards him at blurring speeds, both throwing punches towards at his face. All Might simply squatted down, letting their fists glide over him.
"Haa!!!" All Might yelled before he quickly stood up, slamming both his fists at their stomachs. Both Sukuna and Izuku grunted as they were sent flying yet again.
Bakugo scowled. He stretched out one of his hands, before using his other hand to form a circle on the palm of his outstretched hand. He focused the path of his explosions into a single point instead of around his whole palm, firing a concentrated blast towards All Might.
All Might saw the attack coming and raised his hand, blocking the attack with just his palm. Bakugo narrowed his eyes, before rapidly firing more of his concentrated explosions at the pro hero.
"A new move! You've improved, young Bakugo! But this isn't enough!" All Might declared, dodging the blasts with a grin, which annoyed Bakugo instead of making him feel safe at this point.
'One For All 20%! Delaware Smash!' All Might noticed Izuku firing four compressed air blasts him from behind. He leaped up to the sky, dodging them, before Sukuna suddenly appeared before him in mid air.
Sukuna threw his fist forward towards All Might's chest. The man's response to his attack was to aim a punch towards the teen's fist. They entered a clash, sending a giant shockwave which devastated their surroundings.
'What?! I'm using full power, but he's still—' Sukuna's eyes were wide as he was launched back down, slamming violently into the ground. He coughed out blood, laying in a crater.
'Amazing, this kid forced me to use 40% of my own power off the rip!' All Might thought to himself, sweat dripping a little. Turning around, he saw Bakugo and Izuku dashing towards the exit, taking advantage of the pro hero being distracted.
"Oh no you don't!" The two teens heard All Might shout from him, with them only increasing their speed.
"Guard Railll!!!!" Izuku grunted as he was suddenly pinned to the ground with a guard rail from above, courtesy of All Might. Bakugo watched as All Might charged towards him, intending to punch him again.
"Nuh uh!" Bakugo shouted, using his explosions to move himself, dodging an uppercut. He then held his hands out again.
"Bang!!" All Might grunted a little as Bakugo fired another point blank stun grenade, this time an even more potent version, immobilizing the pro hero for a moment.
When the blinding light disappeared, Izuku and Bakugo were gone. "Come out come out wherever you are!" All Might shouted. Bakugo suddenly appeared from behind, firing multiple concentrated explosions at him.
The explosions landed on All Might's back, as the pro turned around to look at him. As soon as he turned around, All Might noticed something, one of Bakugo's Grenadier Bracers was missing.
"Do it, Izuku!!!" Bakugo shouted. All Might widened his eyes a little as Izuku suddenly appeared behind All Might, releasing the grenade pin without wasting another second, blasting an immense explosion at All Might at point blank range.
The explosion, having the output of a missile's, engulfed All Might and devastated the road behind him. Izuku and Bakugo didn't waste a moment, as they started heading towards the exit.
"Hey! I feel kind of hurt that you're ignoring me like that!" The two froze, turning around to see that All Might was walking out of the debris, visibly unscathed, only having a small line of blood flowing from his lower lip.
"You're not going to get rid of me that easily!" He declared, preparing to charge at them once again. But then he stopped, as someone appeared between them.
It was Sukuna, and he himself was also visibly unscathed, only having some lines of blood under his lower lip. The teen was grinning at the pro hero.
"I admit it, All Might. For you to get rid of me like I'm some fly. Yeah.... There's no doubt about it... You are the greatest..." Sukuna muttered before sliding into a fighting stance.
"But despite that, I ain't scared of you. So come at me." Sukuna declared, looking back at his two teammates, signalling them with his eyes to start running.
"Ho? So you're offering to be the sacrificial lamb? How heroic of you, young Sukuna!" All Might declared, charging towards Sukuna, throwing a punch as soon as he arrived in front of the teen.
Sukuna grunted, feeling his bones crack as he flew straight into a building. Ignoring the pain, he charged towards All Might again, as the fight shifted into a heroic slugfest, a fight full of fists and durability.
Sukuna was punched in the face, spitting out blood before he looked back at All Might, sending a kick to the man's side. All Might grunted, but still grinned, grabbing Sukuna's leg in time before throwing him into a building.
The next second, Sukuna flew out of it, his body instinctively healing his injuries before he and All Might fought again. But it was clear for anyone watching that Sukuna was losing, and he was losing badly.
"You are stubborn, young Sukuna!" All Might shouted. Sukuna grunted, blocking a karate chop from the muscular hero.
"You're trying to hide it, but I can see it clear as day! Quirks are like muscles, young Sukuna! I can tell that you're pushing yourself! If you keep this up, your body will tell you to stop, and it won't be a pretty sight!" All Might warned. With the constant regenerating, and the constant need of pushing past his full power, Sukuna was straining himself as time passed.
"Just shut up and fight!" He growled out, before he gasped. He was hit straight in the chest by All Might. The air detonated and the ground caved in. His ribs cracked, before it quickly healed.
All Might, seeing that Sukuna was still standing, decided to attack him again. Sukuna braced instinctively, grunting as he blocked the punch with his arms, being sent back from the force.
He got up again, charging straight at All Might. He was hit again and again, but Sukuna wouldn't give, it wasn't in his nature to simply give up like others.
All Might punched him again. Sukuna blocked it, but then he felt it, a lag of sorts. His healing didn't snap instantly. The inconsistency was immediately noticed as his arms were back at peak condition.
Sukuna snarled, a little annoyed at the strange activity happening within him. On the next exchange, he instinctively tightened something internal, though it wasn't his muscles. It was something deeper. It felt like a pressure in the spine, a tightening behind the sternum.
As All Might's punch landed, he realized something, the punch hurt less. Something had responded to his 'tightening'. He let All Might swing again, this time he focused on that internal pressure, this mysterious 'weight' inside his body.
The punch landed again, debris exploded outwards as Sukuna flew back yet again. All Might stared, eyes narrowing. "Stop, young Sukuna." He muttered. "There is no shame in giving up."
He sighed as Sukuna walked out of the broken building, though there was something different to him. His annoyed expression had long disappeared, replaced by a look of concentration that unsettled All Might.
"I understand it now..." Sukuna muttered as he looked at his own hands, a fiery reddish-black energy around it. No wonder why his healing was automatic, and his strength was naturally reinforced.
"How did I not notice it before?" He snorted a little. 'So it seems I have an energy system... I didn't notice it before because it was always running at max capacity in the background. How interesting...' He shook his head.
The truth was, his physicality was never purely muscle. It was always reinforced, always buffered, always fed by something beneath it.
And now that he had expended most of this energy fighting against All Might, he finally felt it for himself. He didn't noticed it before because it wasn't something he emitted, it was something he was.
"Something's different about you. What happened?" All Might asked, wondering what that darl reddish aura around him was as Sukuna slowly walked towards him.
"You can say I had an epiphany, All Might."
The fight wasn't over just yet!
And it'll continue on the next chapter...
