The place was different than the place you stayed.It was more modren.It was night time.You didn't noticed that people are looking at your katana.

"Oi Kid.Drop that sword!!!"You look where the voice was.It was two police.They are the same like always.

You sighed and sprint."Using your Quirk is illegal!!!"That make you confused.

"Quirk?What is Quirk?"You thought as you stop when the bandages tie you.

"I see"You muttered."How are you guys slay demons without quirks?"Tsukauchi ask you in confusion.

"Can I get my katana?"You ask them.Aizawa hestient a bit but hand your sword.

"In my word.There's a way.The Breathing Style.For example like this"You unsheathe your sword.
You do simply breathing and the mist surround the whole waiting room.

"Even you guys can do it....if you train physically and emotionally.Training like hell"You told Aizawa and Tsukauchi.Aizawa use his quirk on you but the mist didn't disappeared.

The Mist slowly disappear when you stop."Do you believe me right now?"Tsukauchi nod and Aizawa who still look you.

Everything is solved but one thing that make you question."Where am I going to stay?"


"This is your room"Aizawa show you where your room was."Thank you"You thanks Aizawa.

Aizawa hum."If you want something.My room is next to you"You nod.

There a room that unfamiliar to you.More like modern.You lay on the bed."What happen to Mui-Nii?"You thought as you were greet by darkness.

Aizawa lazily patrolling and capturing villains.He thought one thing.
