To the Fallen

Jujutsu High, Kyoto

Naoya kicked (y/n) in the stomach which broke him out of the pane and he was sent sliding back to his original spot across the roof tiles

Naoya:hmph, is that all a "Special Grade" has got? Or are you that rank for another reason?

He pointed towards his own head

Naoya:are you just slow up here? Dumbass.

(Y/n) slouched forward as he let his arms dangle in front of him with his eyes remaining half open remaining solely focused on Naoya

(Y/n):...

Naoya vanished again and appeared behind (y/n) throwing a right straight which connected to the back of (y/n)'s head as Naoya followed up while circling around (y/n) clockwise throwing a left jab, right straight, two left straights, a right hook and a left high kick to the head as he made it around to (y/n)'s right side

(Y/n)'s eyes jerked to his right as he turned around while pivoting on his left foot and swinging his right heel towards Naoya's head

Naoya ducked under (y/n)'s foot as he tapped the backside of (y/n)'s right leg and (y/n) became trapped inside another pane

Naoya:thought you'd be faster!

Naoya threw a right haymaker as he stepped into the strike, putting his entire arm, back and even his legs into the strike as his fist collided into (y/n)'s stomach smashing him out of his prison and sending him flying towards the track field of the school

Just before (y/n) collided with the field he flipped himself upward as his bare feet began skirting across the dry grass as he slid back several meters before coming to a halt

(Y/n) stood upright, his nose was bleeding and the several strikes Naoya had thrown previously had clearly landed

(Y/n):Your quick.

He spit out some blood onto the field as he tilted his head to the side causing his neck to crack

(Y/n):*A blatant speed type. Even if I was in top form, we'd probably be equals in terms of speed. If not, he might even be a bit faster.*

(Y/n)'s binding bow was never undone, therefor he'd never required his own heartbeat.

During the three days (Y/n)'s body remained in suspended animation due to the efforts of his friends to save his life, his body.
Now lacking a pulse, subconsciously began preparing to ensure its future survival underwent metamorphosis.

(Y/n) tilted his head to the opposite side as his neck cracked again as Naoya appeared before (y/n) leaving a few meters between them

Naoya:Not using the fabled Limitless Technique? Or is it that you can't? Either way, I suppose you make for a good punching bag.

In other words, to prevent a similar occurrence to the life threatening scenario his body reflexively created a system to operate his own pulse subconscious and then optimized that system to the point that his body could generate cursed energy faster then it was burned.

(Y/n) stood upright as he placed his right hand on his hip, eyes still half open and dead serious

(Y/n):Would you use a shotgun to kill a fly if it landed on your arm?
