"Who are you?!" Casio's eyes widened.
Unexpectedly, the imposter immediately dashed towards a corner. Five seconds later, he was apprehended by Casio, his throat clasped by a muscular arm. He was forcibly pulled into a nearby alcove.
"Heh heh heh . . ."
The imposter's throat emitted a wheezy, broken sound.
"Speak! What exactly are you?!" Although Casio apprehended the imposter, a chill of terror still ran down his spine. He'd noticed the absence of his own shadow!
"Hee hee hee." The only response from the imposter was a cold laugh.
Suddenly, Casio felt the other "him" in his grip grow bigger, taller and stronger. This was immediately followed by violent struggling, the imposter violently elbowing back.
The blow landed hard on Casio's belly with great strength.
Casio grunted, determination flaring in his eyes. His right hand tightened, the trained muscles in his arm as hard as steel. With a pull from his left hand, exerting force in one direction.
