Synopsis: The Strongest Hero: Envoy of Darkness -Betrayed by His Comrades, the Strongest Hero Joins Forces with the Strongest Monster-

Known as the fabled "Hero of Darkness," Shion was deemed the mightiest of all heroes. He believed strongly in his comrades, pledging to vanquish the Demon Lord by their side. Tragedy struck when these very girls he trusted implicitly betrayed him, shattering his heart and causing a profound wound in his soul. Hopelessness consumed him as he wandered aimlessly through a forest, searching for a means to end his miserable existence. It was here that a solitary monster crossed his path, begging for the mercy of death. Despite no longer possessing his godlike abilities, Shion's impressive physical prowess remained. The monster's plea shocked him, for he too yearned for the sweet release of death. Thus, he was forced to make a difficult decision.
