"Gum-gum: Jet Pistol!" The arm of the boy wearing red stretched and retracted at incredible speeds, covering a large distance in a blank of an eye.
"As I've told you, it doesn't—" The sound of an invisible, deep-sounding gong rumbled throughout the air as a fist filled with flames hit my chest. Or, rather, hit the infinity between his fist, and my chest.
"Damn it!" The red-shirted boy said, his eyes honed in on my head. He destroyed the dirt ground as he kicked his body sideways, disappearing from my vision. The hissing sound of water turning to steam played around me. One second the sound was behind me, the next second it was in front.
His body was red and steaming at the same time. I don't know what he said, but he clearly didn't like the fact that I was working as a Marine.
"Gum-gum: Jet Bullet!" He was on my left side, aiming at my head this time. This time, unlike his first attack, he was much closer. Close enough that I can see the scar on his chest rather clearly.
"Cursed Technique, Reversal Red"
The red-shirted boy's eyes then widen as his straw hat gets blown away alongside his body. Screaming as the by-product of my cursed technique sends him flying in ways he cannot control, the shockwaves of wind rushing away from him as his body strikes the ground, leaving only large craters behind. He was hit in point-blank range by my Red, a technique that repels objects with unrelenting force. The ground had shrunken into nothing more than trenches and holes.
The boy's eyes were blank as his expression told the rest of the story. His jaw opened wide as the muscle tensions within his entire body loosens up: he was unconscious. He is unconscious, but his arms cradle his chest, and his legs had stayed planted in the ground. Standing, the boy's eyes stayed blank.
"Wow…" I had no other words. "It's as if his body is made out of a rubber ball."
A chill then went down my spine and my arms tensed without my control. My Six Eyes perceived danger from him.
The birds and other animals around us then begin to fall or drop to the ground, as one by one they all stop moving altogether.
"That technique… feels a lot like a Domain." Walking up to the boy, I was only able to gaze at the furrowed ground where his feet had planted themselves and gawk at his strength. "That wave of energy that hit me just then… what was that?"
All jokes aside, that wave just now was very similar to a domain. Everything around us was hit by something, and it had struck for sure, it even went passed my infinity. Just, what was it?
"Armament hardening…"
A strong punch flew past my right ear and then stretched as far as the eye can see.
"…Bullet"
Finally, the boy's body collapses. "Your bounty is as good as mine now, Red-Shirted boy… but first, I gotta figure out your name."
