Dull thuds echo through the dimly lit gym. Bam— Bam— The punching bag swings violently.
Rei, leaning against the wall, calls out in a low voice, but there is no reply. Kei continues to drive his fists into the bag in silence. The trainer, who would usually stop him, says nothing today—he can't. Something was wrong. Both of them had been acting strange for hours. Their bodies were hot, their nerves sharpened, and they could smell the scent of blood. Sounds were vivid. Something was raging deep within their reason. The hospital diagnosis was singular. 'Acquired Alpha Manifestation.' They thought it was an urban legend, but it was reality. And the worst part was... Kei stopped his fists. Sweat dripped from his forehead as he breathed heavily. He turned only his gaze toward Rei.
