"Kazuto!" shouted Thirteen
"Yes, Sensei?" asked Kazuto
"I saw what you did in the entrance exam, so I give you permission to use your quirk to go call for help!" said Thirteen
Kazuto just nods and then turns and stares at the Nomu. The villains that were there look at each other confused they all then turn to Shigiraki. "Hey Shigiraki!" shouted one of the villains. "Where are those heroes you told us about?" asked a mad villain. "They gave me false information," responded Shigiraki. He then turns to the Nomu and says "Nomu kill Thirteen" The Nomu nods and disappears.
Since Thirteen was distracted and didn't hear what Shigiraki said she couldn't react to the Numo appearing in front of her. Thirteen reacted late and turned to the Nomu she couldn't activate her quirk in time. The Nomu was about to punch her when it suddenly stopped moving, a purple glow surrounds the Nomu. Thirteen turns and looks at the glowing Kazuto. He smiles and says "Sensei don't worry I'll handle this, you go call for help."
Thirteen starts to glow purple and floats up to the air. "Wait don't I need to protect you!!" shouted Thirteen. Kazuto looks at her and gives her a gentle smile. The entrance of the doors opens. Kazuto then sends her to UA to get help. Once she left Kazuto looks at Shigiraki "So your name is Shigiraki correct?" Shigiraki then starts scratching his neck, he then shouts "KILL HIM!!"
All the villains then start rushing to Kazuto. Kazuto puts his palms together and shouts.
"Art is an EXPLOSION!!" Kazuto shouted while activating {Telekinetic Explosion} On the villains.
[Mob Psycho power move]
The villains that we're rushing to attack got hit with the explosion instantly knocking them out and some were on fire. Shigiraki got furious and was about to say something when Kazuto suddenly appeared in front of him and punched him in the gut sending him flying. While he was flying away Kazuto appeared on top of him and grabbed his head and slammed him to the cement floor-breaking Shigiraki's facial bones and Knocking him out. Kurogiri didn't have any time to react to Shigiraki getting destroyed. Kurogiri turns around and tries to activate his quirk but his arms and legs get crushed leaving a ton of blood everywhere.
[A/N What Gojo Satoru did to Juzo in Jujutsu-Kaisen]
All the villains that saw what Kazuto did got horrified expressions and tried to escape, Kazuto noticed this and a grin appeared on his face. He then activates {Super Gravity Waves} slamming every villain in the building to the floor instantly knocking them out.

Class 1-A just reached UA, they walked back to the school after their training got canceled.
"Finally we made it!" shouted a tired Mineta
"It was a fun experience!" shouted a gleeful Mina
Uraraka looked worried and turned to Aizawa and asked him "Sensei where's Kazuto, shouldn't he be here with Thirteen?"
Aizawa looks at her but then turns away "He's fine but now let's head to class." said Aizawa, he then starts to head into the building when he suddenly hears a scream heading to him. Aizawa and the class head outside and they see a flying Thirteen heading to them. She lands on her feet and rushes to Aizawa ignoring her dizziness.
Once she reached Aizawa she says "Villains are attacking the USJ!" Aizawa's eyes widen, the class all get shocked. Thirteen then stands up properly and says "And Kazuto Shio is there facing them alone." The class's eye's widened, Aizawa then turns to [Lida] and shouts "Lida head to the principal's office and tell him USJ is getting attacked by villains and that Kazuto is facing them alone." Lida nods and runs to the principles office using his quirk. Aizawa puts his goggles on and turns to Thirteen and says "Thirteen take care of the students, I'm heading to the USJ!" Aizawa exits UA and starts running to the USJ building.
Thirteen looks at students and tells them to head inside to class.
"Sensei is Kazuto okay? We should help!" shouted Kirishima
Thirteen then looks at Kirishima "We need to keep you safe first."
"What about Kazuto!" shouted Jiro
"We need to go help him!" shouted Kaminari
The class then started to get worried for Kazuto.
~~~
Lida was using his quirk to reach Nezu. On the way there Lida thought "I need to tell Nezu quickly or else something bad might happen to Kazuto." Once Lida opened the door he spotted Nezu talking to a skinny man with yellow hair. Nezu saw the panicked Lida and asked him what's wrong. Lida explained the situation to Nezu. Nezu immediately got into the school's intercom and says "All heroes on campus head to the USJ! It's getting attacked by villains and a student named Kazuto Shio is defending himself on his own." All Might runs out of the office and heads to a window.
~~~
Vlad King just finished telling his students about the test there going to have when Nezu says something on the intercom. Vlad King turns to his students and then leaves running to the USJ.
"Kazuto's in trouble!" shouted a worried Rin
Shiozaki starts praying and says "Oh the lord please don't let anything bad happen to Kazuto he means a lot to me."
"Oh no Kazuto," said pony
The students that have ties with Kazuto started to get worried. Kendo stands up and looks at her classmates.
"Kazuto is strong he can protect himself he'll be fine," said Kendo while trying to calm down her classmates but in her head, she was completely worried and afraid.
At a different seat was a girl with an expressionless face but once she heard the intercom her face changed and she started to get worried for Kazuto.
~~~
Back at the USJ Kazuto was standing on top of Shigiraki's unconscious body he turns to the Nomu and snaps his fingers for added effect. The glow that was around it disappears. The Nomu stays still waiting for Shigiraki's command. Kazuto then turns to Shigiraki and lifts up his head from the ground.
"Hey Shigiraki wake up," said Kazuto while staring at Shigiraki's messed up face. He then sighs and starts breaking Shigiraki's bones one by one hoping to wake him up. Kurogiri lifts up his head and sees what Kazuto is doing to Shigiraki. He opens a portal under Shigiraki, Kazuto notices this and jumps away from Shigiraki letting him escape. Once Shigiraki got warped away Kurogiri also warps himself away.
