The Return of the Corpse King: I, the Former Hero, Summoned Once Again to Another World to Stop the Chuunibyou Secret Society I Formed.

Once, there was a hero named Shio Hizaki, who saved another world. All his classmates who were summoned together with him died, and after defeating the Demon Lord, he was forcibly sent back without any rewards. Overcoming a gruesome past with the support of those around him, he graduated from high school. Shio was once again summoned to the other world by a woman claiming to be a goddess. “Hey, our world is in trouble because of this Helheim thing, so do something about it.” “Well, I’m the one who created that organization, you know…!” Tortured by the responsibility of creating the organization, Shio struggled with his dark history, but now he must traverse the world to stop the rampaging “Helheim.” “Welcome back, King of the Dead.” With his former subordinates gathered around him, Shio once again treads the chaotic world.
