The sterile hum of the laboratory filled the air as Dr. Kiryo Sabato meticulously deleted files from his database. In the adjacent cell, the sound of frantic banging against the metal door echoed his obsession. He paused, adjusting his glasses, his grey eyes cold yet fixated on the captive who had once killed him. The chains on her ankles glinted under the harsh lights, a stark contrast to her naked form draped in a thin nurse’s robe. He rose, the dark green tentacles writhing subtly beneath his lab coat, driven by a twisted need to preserve her beauty while stealing her cells to halt his own demonic transformation.
