The Green Ninja dedicated his life to protecting mankind from terrors most only witness in their darkest nightmares, and few could rival his combination of skill and luck. When his luck took a turn for the worse, that life ended, and he suffered a fate more tragic than death: a new existence among the very abominations he was sworn to destroy. Now the Guild of Ninjas, who were once his allies and closest friends, are seen as enemies in his eyes. Can his former comrades overcome his new form, a monstrosity forged in Hell who was nearly unstoppable in life, or will the world's most elite warriors fall victim to the Green Demon?
