6 Smash

Author's Note

I think there's some confusion on how Infinity works. Whenever he casts a spell, it does use mana, but it will never disappear until he wills it. For example, if he froze someone, they would stay frozen until he willed it to disappear or they could break it. It still uses the mana, the effect just doesn't end.

--------------------------------------------------------------Two weeks passed with everyone doing their best to train for the UA Sports Festival. While the rest of my class was stressing about how they would in the the festival, I was focusing on developing my skills as much as possible.

At the end of the two weeks, my skills had progressed a good amount.

[Armament Haki: A form of Haki that allows the user to use their own spiritual energy to create, in essence, an invisible armor around themselves, providing incredible offensive and defensive capabilities. Lvl 5/10

One For All: Allows the user to stockpile an enormous amount of raw power, allowing them to significantly enhance all of their physical abilities to a superhuman level. Lvl 5/10 Max Output without Damage: 80%

Observation Haki: A form of Haki that grants the user a sixth sense that allows them to sense the presence, strength, and emotions of others. Lvl 5/10

Geppo: Allows the users to actually jump off the air itself, allowing them to stay in the air for much longer than usual. 3/10]

My awareness with Observation Haki had grown a lot, managing to cover the entirety of All Might's house with it. Geppo could be used longer in the air and my Armament Haki was stronger than ever. One For All was strange, though. It hadn't leveled, but my maximum output was increasing. I assumed it would hit level 6 when I got it to 100%, but I wasn't sure how the last 4 levels would behave.

I was currently walking with the rest of class 1-A out to the stadium where the festival would take place. Right before we exited the tunnel, Todoroki sidled up next to me and said "Know this Emiya, I will beat you."

"Good luck with that" I said, giving him a thumbs up. At my current power level, no one in UA was a match for me. I was almost to All Might's level, most pro's couldn't do much against me.

We walked out, with the other classes walking out of adjacent tunnels. We formed a semi-circle around the podium, where Midnight was standing. The stadium was filled to the brim with people. All different kinds of heroes could be seen, looking down at us, waiting to see how we would perform.

"Give it up for all of UA's first year students" Present Mic's voice could heard, roaring over the crowd cheering.

"Silence everyone. To give the student pledge, Shirou Emiya." Midnight said.

Shrugging, I walked up to the podium. They had said something about me having to do it since I was first in the class, but I hadn't really thought about what I'd say until now.

"Try to keep up" was all I said before turning around and walking back down.

There was outcry from the other classes, but much like Bakugo, I didn't really care. Some meaningless words in the beginning didn't matter, if you couldn't compete, you couldn't compete.

"And with those rousing words, let's get on to the first challenge." Present Mic said.

He then went on to explain that we would be doing a race, with obstacles placed along the path. Everyone crowded into the large tunnel where the starting line was and waited.

"BEGIN!" was yelled by Present Mic as everyone began to clamber to try to get out of the tunnel. The ground began to freeze as Todoroki's attack passed through the entirety of the tunnel. Jumping up before it could reach me, I dug my hand into the roof of the tunnel and waited as the ice passed by. Dropping down on top of it, I activated One For All at 15% and dashed forward, running past all of the people trapped and continuing after Todoroki, who had already left the tunnel.

I could hear Bakugo raging behind me and his explosions sounding off as he escaped as well. I quickly caught up to Todoroki, who wasted no time in freezing the zero pointers. I caught up and passed by him, waving behind me.

"See you at the finish line."

I didn't use my full speed, there wasn't a point and I didn't want to straight up dishearten everyone. I maintained my speed at a level that I was a good ways ahead of Todoroki, but I wasn't completely off in the distance.

Bakugo and Todoroki continued to try to push themselves to catch up to me, completely surpassing everyone else in the race as they moved as fast as they could, but I crossed the finish line first by a good distance.

Bakugo and Todoroki panted as they crossed the finish line. Bakugo looked at me and rushed forward, grabbing the scruff of my uniform.

"I will win the next challenge. Count on it."

He released me and walked off the side as he waited for everyone else to pass the finish line.

Once everyone was done, Midnight explained the next challenge to us. The top 42 advanced while the rest didn't. I was handed a 10 million point headband and everyone was told to form a 2-4 person team.

Looking around, I could see everyone avoiding coming near me since I was the most likely to be targeted. Looking for people I knew, I saw Momo teaming up with Todoroki. Somebody tapped me on the shoulder. Turning around, I found Ibara and Jirou.

"Got room for us?" Jirou asked.

"Yeah, but why be on my team? I'm the biggest target."

"Because you're the strongest person in our year. I don't think anyone can take it from you. Isn't that right Ibara?" Jirou said.

Ibara nodded. "You're too fast for them."

"Alright, then we're a team. I'll be on top if that's alright with you two?" I asked.

"That's fine, we'll hold you up." Jirou said.

I was lifted onto their shoulders and put the headband on.

"Ibara, if you can try to deflect some attacks with your vines, that would help. Jirou, make sure we aren't caught by surprise."

The both nodded.

"BEGIN!" Present Mic yelled once again.

'Someone needs to turn him down' I thought with my ears ringing.

As soon as the word begin was heard, everyone began to rush at us. Bakugo's team was in the lead, running at us when someone swiped his headband, causing him to take a detour and chase them.

Todoroki had frozen a lot of people and was coming for us. Ice slid along the floor towards Ibara and Jirou's feet.

"Watch out" I called out.

Ibara used her vines to root herself and Jirou into the ground, making sure they wouldn't slip and fall. It had the side effect of making us completely immobile, however, so the teams soon converged on us.

Todoroki sent a wave of ice into the air, but I sent a 50% punch and destroyed it. I noticed tape coming toward me with Observation Haki, but I didn't react, instead letting Jirou call out "Shirou, behind you."

I reacted, grabbing the tape and pulling, ripping it off of the source.

'I can't do everything. My teammates need to participate too.'

All kinds of different powers attack us when I sensed a spherical object flying toward me. Looking at it, I found a purple orb flying in my direction.

'So Mineta is here somewhere.'

I moved my head out of the way, letting the ball fly by me as I defended myself from another of Todoroki's attacks.

The cavalry battle continued, with us managing to not lose the 10 million point headband at all as it came down to the last five seconds. As Present Mic counted down, Bakugo came flying towards me, trying to grab the headband.

I watched as he neared, trying to get close, but instead of me blocking him, Ibara did it. She wrapped her vines around his leg and flung him away from us.

"Ha, nice Ibara."

"Time's up. Lets see who has the most points." Present Mic called out.

Like canon, the team Shinso mind controlled into carrying him forfeited, leading to the people that advanced being me, Ibara, Jirou, Ida, Momo, Todoroki, Uraraka, Shinso, Mina, Kendo, and Tetsutetsu.

"We have an odd number of finalists, so Emiya will be automatically advanced to the next battle due to having won the first challenge." Midnight announced.

"We will not draw the lots to see who will be going against whom in the final challenge, which is a tournament battle." Midnight said as she reached into a bag to pull out lots, but before she could an explosion occurred. The stadium shook as smoke began to rise from a hole in the wall. From it poured large groups of villains, who began to attack the heroes in the stands.

'Shit, okay, so me preventing the ringleaders from escaping led to them attacking here instead. Why move up their plans though?' I thought, but had to move as a villain attacked me. All around battle was happening as various heroes and villains fought. I could see Mt. Lady rise up as she grew and battled another giant villain.

'Attacking here doesn't serve any purpose. So many heroes are here that they're guaranteed defeat. Unless, it's all a big distraction. With most of the heroes here, they can move to free Tomura. He's too important for All For One to leave in prison. I need to find All Might.'

Spreading my Observation Haki as far as I could, I searched through the stadium for All Might. I couldn't find him with my range being where it was, so I activated One For All and became a blur as I sped around the stadium, looking for where he could be. I eventually found him, defeating villain's as quickly as they could come for him.

"All Might, this is a distraction. They're trying to free Tomura." I said to him quickly.

"Well then we should go stop them now shouldn't we." He said, sending another villain flying as he jumped out of the ran out of the stadium. I quickly followed him as we both made our way to the Police Department, where Tomura was being kept under high security along with Kurogiri.

When we arrived, we found the building collapsed. I searched with my Observation Haki, finding Kurogiri standing with a group of villains and Tomura.

"Over here All Might" I said, moving as fast as I could as I saw Kurogiri open a portal to take them away.

All Might moved past me, grabbing ahold of Tomura's arm before he could walk through and yanking him back, pulling him out of the portal.

"Haha, yes All Might. I'll be sure to kill you right here." Tomura laughed, trying to wrap his hands around All Might's wrist, but All Might pulled his hand away before he could.

"Kurogiri, summon the Nomu." Tomura said.

"Leader said we should head straight back." Kurogiri replied.

"We have All Might right here. We can kill him now!" Tomura yelled.

"You're always so quick to act Tomura. Action should be taken when you're ready." A voice said as a man stepped out of the portal. He was tall, wearing a suit and his face was covered by a mask.

"All For One" All Might growled.

"Hello All Might, miss me?" He asked.

"You shouldn't have crawled out of that hole you were hiding in. I won't let you roam free this time." All Might said.

"You sure. You're getting on in years All Might, I don't think you can handle me."

Instead of answering, All Might dashed at All For One, throwing a punch that was met with one by All For One. There exchange became a blur of exchanges as the two continued to fight each other.

While they were fighting, I turned to Tomura and appeared behind him, knocking him out with a chop to the neck.

Looking for Kurogiri, I found him already having warped the rest of the villains away. Sensing a portal opening behind me, I threw a Haki enhanced punch back, shattering the portal. Running at Kurogiri, I used my Haki to coat my hand and grab onto his body, knocking him out like Tomura.

Turning and looking at the fight between All Might and All For One, the city street we were on was getting torn up. Buildings were crumbling as the damage the two did to the surrounding environment increased.

Hearing a noise, I looked up to see a news helicopter flying above, recording the fight.

'This is happening way sooner than it should be. I know Tomura is important to All For One, but enough to move up his plans entirely?'

I watched the fight and I could see that All Might was slowly wearing down. This was different than the anime, where All For One had basically spammed one combo he though worked. He was using all kinds of different quirks. Spikes were coming out of his body and electricity was flowing through each of his punches. One of his punches caused a soundwave to go out that made my ears bleed, and I could see All Might's ears bleeding as well.

'All Might's going to lose.' I realized, looking at the battered form of the Symbol of Peace. His costume was in tatters and I could see him breathing heavily. Maybe if he was at his prime he would be able to win, but he couldn't keep up with the versatility of All For One anymore.

He finally reached his last legs and he began to steam, shifting back to his emaciated form. All For One grabbed him by the neck and held his body up, showing the cameras above.

"This is your Symbol of Peace! He's nothing but a frail old man, trying to cling to some notion of being a Symbol." All For One said, his voice carrying with the help of some unknown sound quirk.

I charged up One For All past my limits, getting it to 100% as red electricity flew all around my body. All For One turned to me as I kicked off the ground, flying toward him and delivering a punch that sent him skidding back and released his grip on All Might, letting me grab him.

"How you feeling Toshinori?" I asked him.

"Shirou" Toshinori said.

"I'm not. You have anything left in the tank?" I asked him.

He pushed my hand off him and stood on his own, saying "I've got one more left in me. If this is the end of All Might, I'm going out swinging."

"Alright, together then." I said, holding my fist out.

"Together" he said, meeting my fist bump.

"This is touching, but don't think you still stand a chance All Might" One For All said.

"Wanna bet?" I asked as All Might and I both began to have lightning around us. His was a light blue while mine was the same color as my hair. We both pushed off the ground as All Might's legs shifted into his hero form's for a second, giving him the strength to speed over to All For One with me.

All For One tried to form rock barriers from the ground to stop us, but we blew through them and appeared in front of us, both rearing our fists back as All Might's legs returned to normal while his arm buffed up again.

"United States of Smash!" we both yelled, delivering two 100% punches to All For One, caving his chest in and sending him flying through several buildings before coming to a stop. Much like All Might's injury, All For One now had a crater in his chest and his head laid limp.

All Might began to cough up blood and fell to his knees, his arm reverting to normal as he collapsed, unconscious. I got him before he could hit the ground, holding up the now powerless Symbol of Peace.
