But Chronos is determined to conceal their secrets at any cost. Sho soon finds himself relentlessly pursued by an army of horrific bio-monsters. With nowhere to run, Sho is forced to call upon the fearsome power of the Guyver and rip his opponents limb from limb in a desperate struggle for survival.
