From Death To King

Explain

"I was brought back as a demon... With the soul of Genocide..."

"Genocide!? Nononono!! He's been in jail for hundreds of years!! All he wants is to cause chaos..."

"W-Wait who are you..?" I stood.

"Oh! Yes... Where are my manners? Sorry about that. I'm Matrix! Tier ten Demon. Ruler of hell." He smirked.

"Ruler...?"

"Yeah. You have to work up and then you get given tiers by me. Speaking of which." He placed his hand out.

"A-Ah!!! Stop!! I've been through this too many times!!!" Every single one of my features came back.

"Sorry... You have to be like this. This time there's no way to become human again because you are, in fact, a demon. Rather than being possessed by a demon you are the demon and can possess others."

"So I'm a tier one demon?" I looked up at Matrix.

"Yeah. Tier ones work at the mines but... you... well..."

"I'm too weak... right...?"

"Yeah." He sighed. "Where is Genocide?"

"Oh! Shit!!! He possessed a student of mine! He wanted to destroy the city!! I... I have to stop him!!"

"Toshinori! You can't! You are far too weak to fight him."

"Well... Can you not just give me more tiers?"

"I guess so but... going from tier one straight to tier ten is the most painful thing ever... you could just... die... you'd go to the next place which is much worse... constant battling..." Matrix sat down on his thrown.

"You healed me... Can you not give me them potion things to stop the pain while doing it?"

"You really won't retire, will you?" He laughed.

"No! Never." I smiled.

"Your idea is quite smart. It would work. Painful... But you wouldn't die. Still wanna do it?"

"Hell yeah!! I've been through bad pain before."

"What..? Oh- You're scar..." He sighed. "Lets do it. He came down to my level. "Do you know what's going to change?"

"Uh... No..." I admitted.

"Most likely you'll become taller, grow more horns, stronger wings and tail, your feet will change to digitigrade so you may need to relearn how to walk..."

"Right... Anything else?" I sighed.

"You may get other features... Not really sure what..." He placed his hand out. "Ready?"

"Yeah... Just get it over with."

Red and black smoke appeared around me. It soon engulfed both me and Matrix. "This doesn't hurt that ba-! AH!!"

"Spoke too soon."

"Aaahh!!!" I wanted to scramble away but I had to stay put for the sake of Midoriya... For the sake of the city...

My body began stretching. It was like a growth spurt but with worse pain. The pain shot straight up my spine and spread across my whole entire body.

"Almost done, hang on."

"D-Done... wha..?"

"Just the growth part of it."
