17 USJ, confrontation.

Sekizan jumped into the fray. The mob villains immediately began to attack him, a mutant quirk user with reptilian like mutation jumped at him with his claws, trying to cut him apart.

Sekizan easily dodged the villain lunge and countered with a punch on the tip of his chin. Rattling his brain, being a mutant type he resisted the punch without falling unconscious, but did not get the chance of regain his footing as a kick found the side of his head, making his get knocked out immediately.

Sekizan was like a wolf among a pack of sheep, using minimal movements to knock out the villains using only one punch. When the villain had a endurance type of quirk he used Shigan to incapacitate or cripple, leaving them to his luck, he did not want to waste time with those weak villains. He was trying to bait the big bad guy, conserving energy to the most difficult fight of his life.

Getting close to Aizawa he observed the technique of his professor. He was impressed, even though it was a more un-letal type of martial arts, more focused on apprehend villains. But he respected him, he did not have a quirk who gave him the attack power, but it levelled the playing field and allowed him to fight and be a great hero.

Aizawa in turn saw the efficiency of his student and the brutality of his movements and was in shock. He didn't know martial arts could become like that, and the cold-bloodedness of the way Scarlatti dispatched villains worried him a bit.

' I got to have a talk with him after this is over.' He thought seeing him approaching.He saw him kick at him and involuntarily dodged making the kick hit a sneaky villain who had sneak close to him without him noticing.

" Get your head straight sensei." Sekizan said seriously, he was not expecting a veteran to get distracted. Not noticing that it was his actions who worried the poor professor, making him distracted.

" Thanks, you as well. This invasion seems planned. Be careful." Aizawa said. He was feeling a little guilty about doubting his student,but he didn't put much thought in it right now.

They continued to defeat the villains with surgeon like precision, until the villain who looked like the leader got annoyed.

" This two are getting in the way of our plans. Nomu go deal with them." Tomora said, giving the order.

The giant goliath vanished from his side, intent on following his orders.

Sekizan was in the middle of knocking another villain when he felt a sudden spike in his danger sense. The air pressure became imbalanced and he immediately found the direction of the danger.

He saw the giant bird man about to smash his teacher to a paste.

*Soru*

Sekizan instantly appeared behind his teacher, caching him by the scarf using his momentum to evade the punch coming from the above.

*BANG!*

The floor ended up being the unfortunate target of the punishment dished out by the nomu.

But he didn't stop, immediately he attacked again.

Sekizan felt the wind pressure of the punch, he throwed Aizawa away, and tried to concentrate on the enemy in front of him, watching the creature wind-up another punch.

*Fuuhhh*

Using a mixture of Kami-e and footwork to dodge this punch the mc used his opponent momentum to counter, aiming at the solar plexus.

*Bang*

Looking for a reaction from his opponent he got instead another punch, even faster than the first one.

*Fuuuuhhhhh*

The wind pressure of the punch made it difficult for him to steady his feet, using Geppo he dodged to the side again, maneuvering in the rough winds this time sticking at his opponent's liver with a roundhouse kick.

*BANG!*

Still, no reaction. Preemptively evading he used soru to get some distance and Geppo'ed to get more momentum. Using Geppo again in conjunction with gravity he front flipped into a axe kick, aiming now at the exposed brain of the creature.

*BAAanG*

But the bird man was relentless. Dishing a uppercut in retaliation.

Sekizan barely dodged, the wind of the punch coming so close that his skin was cut, making him bleed.

Back flipping into a standing position he proceeded to change tactics. Making claws and using speed to incapacitate his opponent to give him a chance to dish out a stronger move.

The Nomu continued to dish out punches and Sekizan continued evading by the skin of his teeth, countering by cutting the ligaments of the goliath at every move. Trying to get time.

All of this happened in just a few seconds. Aizawa was seeing this and was worried. His student was dodging the punches by so little that he was getting cut so much that the blood began to soak his clothes making him look terrifying.

Sekizan passed 20 seconds on his most heated trade of punches and finally saw a chance, the nomu was kneeling after he spend great efforts in severing all the tendons of his limbs. Not wasting this opportunity he prepared to test a thing that he was working for several years on this enemy!

Liberating his body limitations and pumping his adrenaline and speeding his heart, in a technique he called 'Release'.

Getting in position he put his two fists in front of his opponent he tried a move he trained all his life for.

"Rokuogan! Hah!!" He shouted, using all his muscles in a wave like manner to dish out the true expression of the rokushiki style.

*Ziiioong*

A shockwave spread throughout the body of the nomu making his flesh and insides to collapse, his skin to tear and his eyes to explode out of his sockets.

Sekizan was a little tired, that move took more than he was expecting, slowly he began to get upright and was met with a giant fist standing right in front of him.

' Shit.' He couldn't dodge this one.

His brain was lighting up a storm, his sinapses were happening so fast that even static like energy was being produced around his head. As the fist connected with his head he did the only thing he could.

As the force of the punch travelled through his body like a destroying shock wave, not so different from his previous move, he redirected the force like a wave through his muscles, lacerating them as the wave passed, sending to his own fist, countering almost immediately, sending another shockwave through the USJ.

*BANG*

*BANG*

There was two sounds one after another, the nomu took three steps back, our mc however was in the same place having used all the kinetic energy he was given.

Sekizan was bloodied and in rough shape. His nose was broken, his lips and eyebrows were torn open and blood was soaking his intire face. If he did not had transfered the force of the punch he surely would have died or at least crippled by that punch.

" Hahaha it's that all you have bastard! Come at me again bird brain,I can do this all day!" The image of a bloodied 1.90 ginger with bloodshot eyes and a manical grin after being pounded by a punch capable of destroying a building was a sight that no person was expecting to see today. They were paralysed by the intensity of his voice.

" Uhh NOMU! KILL THIS BASTARD!" Shigaraki Tomura was pissed about being intimidated by a f*cking brat, and immediately ordered the nomu to finish the job.

"Wryyyy!!" The Nomu made a astringent shout and punched again, much stronger than before, having healed from the damage taken beforehand.

Sekizan could not move at the moment so he had to rely on his incomplete martial art that redirected force to survive the onslaught.

His focus was so sharp that his eyes became even more bloodshot, there was even a gleam on them.

' Let's see who can last the longest you broken piece of shit.' He shouted in his mind. Thinking about the amount of quirks this piece of shit monster had.

Receiving another punch he redirected again through his muscles, this time with more mastery, shredding less of his opposite arm. Trading punches with the nomu again.

*BanBang*

"Eughhh, ahhh" Sekizan shouted. Preparing for another punch.

The Nomu continued to punch and Sekizan continued to redirect, everytime he received a punch he became more proficient in redirecting force, everytime tearing less and less muscles. Trading punches after punches, over time he got his movent back and began to evade again, this time using Shigan to repeatedly patter the Nomu in the joints, the eyes, tendons and important muscles. using his release to continue sending endorphins to his system, being able to punch kick and slash as much as he could. Until.

Until the Nomu was in his knees again, this time, he saw that his healing was much more slow than before. The MC was the image of a person who passed through hell, his shirt destroyed, showing his shredded and lacerated upper body with blood flowing from the open wounds. His red hair, soaked in his own blood was sticking on his skin.

Sekizan took a deep breath, using the release again, this time pumping endorphins together with adrenalin, to not suffer from shock because of the pain coursing through his system, he had to end this.

Putting his two fists again in position, trying to maintain steady feet, Sekizan used every ounce of his strength to end this fight once and for all.

" Now you stay down you bird bastard! ROKUOGAN!!!!!"

*VUNGNNNN*

The shockwave spread throughout the body of the Nomu again making his skin explode, the brain that was exposed on his head turned to mush, and finally he stayed down, for good this time, his healing has exhausted apperently.

"Phew." Sekizan straightened up lifting his head to the sky. He did it. His body was not moving currently, and his left eye was shut close, already purple, but he did it. He defeated a overpowered bastard with just his martial arts, he can get even stronger now.

After a breath he looked at the direction of the guy with the hands on his face. His one eye stared at him with boundless bloodlust, slowly he began to walk toward him.

At that moment the door of the USJ blow open and all might showed up looking at the current situation.

A red headed student was bathed with his own blood, and there was a teacher hurt and he saw various students spread across the facility.

" Let's get out of here Kurogiri, the Nomu is down." Shigaraki said. He was a bit uncomfortable with the look of the MC.

The warping fog man, warped the two out of the USJ.

All might did not take long to apprehend the rest of the villains, but when he saw the state of Sekizan he was disappointed with himself.

Our protagonist seated on the floor, focusing on healing. He was playing the fight frame by frame in his mind, analyzing all he could have done, all his mistakes.

' I still have a long way to go.' He thought in a self deprecating way.

He continued to meditate, it was a long day today.
