Ryuhei moved first, his body blurring forward with a speed that defied human eyes, his steps cracking the concrete beneath him as he closed the distance between them in less than a breath.
Seijirou barely had time to raise his guard before Ryuhei's fist slammed into his gut, folding him in half, the air exploding out of his lungs with a sharp gasp.
Before he could recover, another blow struck his jaw, then his ribs, each hit landing with brutal precision, carrying the weight of the dark energy that surged through Ryuhei's veins.
Seijirou stumbled backward, disoriented, his vision shaking, but Ryuhei was already upon him again, his movements smooth and vicious, more like a beast than a man.
A heavy kick connected with Seijirou's side, sending him crashing into a billiard table with enough force to split it down the middle.
The wooden frame cracked and splintered as Seijirou's body bounced once, then fell limp across the shattered remains.
