(Meanwhile/Timeskip)

Yang: really? You have two older half sisters?!

Y/n: yeah and we're trying to search them.

Then a knife hits Y/n's head and they looked at the roof were a girl on top of it.

Deku: that's Himeiko Toga!!

Bakugo: Let me hit her*Gets hit by the head from Weiss* OW!!

Weiss: plan first attack second Bakugo.

Kirishima: BURN!!

Himeiko: catch me if you can!!

She starts to run jumping roofs to roofs they all began to chase her.

Y/n: split up!!

All of them split up and chase her from all angles but she dodges their attacks luckily some attacks did hit her causing her to slow down but they arrived at a abandon warehouse as their base.

Blake: this where she went to.

Asuna: why the lights are off?

The lights were on and reveal Paranormal Liberation Front's the grand commander Tomura Shigaraki and the lieutenants.

Bakugo: Give me break!!

Tomura: well, well look do we have here more quirks to take along with semblances.

Y/n: really steal people's powers to have your own? Coward.

Tomura: stop them.

They all charge at them Tomura tried to attack Y/n with the Decay quirk but Y/n was not even effected by the quirk.

Y/n: tell me Tomura where are my sisters?!

Tomura: why should I? you're nothing!!

Y/n: tell me where are they!?

He snaps his fingers and reveal Rin and Yukio bruises.

Y/n: what did you do to them!?

Tomura: tortured them to give me the details about Satan and your family.

Y/n: you bastard!!!

Tomura: you're very powerful but not enough to save your friends.

Y/n: flame on!!!*transforms into Ivlis* take the heat!!

Shot barrages of fireballs at the all for one quirk user, barrages of punches and kicks sending Tomura straight to the ground.

Y/n: you really pushing my buttons and you'll be payed dearly for torturing my sisters and killing innocent lives from your quirks.

Tomura: turn around fool.

He turns around to see his team, rwby and 1-A students bruised and being hold down.

Y/n: let them go-GHAAAAAAAAA!!!

A giant hand slams him to the wall from Rikiya's stress quirk. Tomura walks towards his team and told them to start to torture his team, rwby and 1-A students.

Y/n: let them go!!!

Tomura: well I'll use my Decay with Asuna first.

Y/n tried to use his demonic powers but hearing his friends scream in pain of agony. His flames burn Rikiya's hands causing him to let go.

Rikiya: fuck my hand!!

Y/n: Let them go now!!

Dabi: why should we let them go?

Mr.Compress: you're nothing but a freak like your faunus friends.

The flames began to go crazy, it's movements were impossible to predict then it exploded surrounding Y/n and his flames were turning blue.

Y/n: because I'll burning your asses to hell as a villain BBQ for Lu's hellhounds, BURN OUT!!

His whole body was covered in blue flames, the air was more hotter than before even Dabi was getting more sweaty. The flames were gone to reveal in but he was different.

Y/n: let them go NOW!!

Spinner: let me hit this weak kid he'll be easy to harm!!

Spinner uses his makeshift sword and swings at Y/n but was blocked by Y/n's sword.

Spinner: what the hell!?

Y/n: Death Stare.

He looks at Spinner and the gecko villain saw it causing his head to explode.

Y/n: Lu rise up my blue flame queen.

Lu: yes my lovely king?

Y/n: take Rin, Yukio, my team, rwby, and the 1-A away from here.

Lu: yes master.

She teleports them away from the building and Y/n was alone with the villains he burns the corpse of Spinner.

Y/n: next?

Mr.Compress: Time to be shrink down kid!!

He runs towards Y/n and touches his chest but no effects did anything shocking them.

Mr.Compress: what the-GHAAAAAAAAA!!

Y/n: Dodge the fast bullets fools!!

Dabi: I'll show true heat!!

He shot a wave blue flames and but Y/n dodges while turning back to his base form.

Himeiko: what's wrong you scared!?
