Festival Maids

The place was dark. It was a building but there was no light. Someone was running.

"Damn it...It is all messed up."

He was running...He was Shido Itsuka.

He kept running without stopping...With him was a little girl running as well, Yoshino.

Yoshino: "S-Shido-san...Where are we going?"

Shido answered her while running, "I don't know...I don't know either. Just keep running for the moment-"

"AAAAHHH!" A high-pitch scream and multiple explosions were heard from the behind.

Shido gritted his teeth, he held Yoshino's hand tighter and kept running faster. 

They then made a turn to the left, just then a couple of explosive bullets hit the wall in front of them and a figure walked out.

"Ya all know, I never trusted yo ass to begin with." The figure's body emitted a lightning aura which made the body visible.

It was G/n S/n, is a full black suit except that the coat was hanged on his shoulders.

G/n: "We all doing this, huh? No point yapping anyways, I high-key thought of jumping the hungry kid but cuz bro said to cap myself, whatever...Hand over the ice loli."

In G/n's left hand was a katana which was very bloody. With a very motion, the blood spattered on the ground before him as he pointed the tip at Shido's direction.

Shido stood with Yoshino behind him, he was panting due to all the running and his heart was beating faster due to how much menace this man in front of him caused in such a short time.

"Sandalphon!" Shido materialized the sword in his hands and stood his ground in front of G/n.

G/n: "Bro, for real. I removed the limiter off my cheat-codes, you ain't doing shit to me even if I pull a AFK over here."

Shido didn't understand G/n's odd way of speaking all that well. But for himself, he knew one thing...

"No..." Said Shido, who now stood straight with the sword in hands, "I won't let you take her away"

G/n: "Bruh, You can't defeat me. I be OP as fuck to the point I can say the N-word. What ya got against me?"

Shido: "I won't stop...*panting*until I seal you-"

G/n: "Fuck your bitch-ass pussy-ass mission of sealing GODDAMN magical girls, you dense idiot."

Shido was shocked at G/n's voice but didn't step back, because he will save Yoshino.

Shido: "How do you even say that?! Look at all these people you killed! There's blood laying around-"

G/n: "I ain't give no fuck."

Shido: "You...You are a monster. That's why I will stop-"

G/n: "Bruh, stop yapping. You ain't Guts or Goku that ya trained like ass to fight some Boss like it's no joke. Ya never trained other than your rizz."

Shido: "I know...I am weak but you are a killer, I have to seal you-"

G/n: "Nigga, Talk no jutsu ain't working on me. Ya got low charisma."

Shido was frustrated and realized that talking to G/n will do nothing.

Shido started to run forward but his eyes suddenly widened when he saw G/n's figure suddenly dash in front of him with a long jump. Shido managed to clash with G/n's katana in time but...
