Return of the Corpse King I, a Former Hero, Am Summoned Back to Another World to Stop the Chuunibyou Secret Society I Created

Resummoned with My Former Chuunibyou Revived? The Birth of an Embarrassing Dark History Comedy in Another World!

“How could my past self have done such embarrassing things with such enthusiasm?!”

Nisaki Shio, a hero who was summoned to another world in his third year of middle school and saved it. After defeating the Demon King and being forcibly returned to the modern world, three years later, he is summoned to the other world again—to stop the rampage of the secret society “Helheim.”

However, it turns out this organization is actually the embarrassingly cringeworthy dark history that he had created when he suffered from chuunibyou, calling himself the “King of Corpses”!?

Who on earth is impersonating “Helheim” and spreading its notorious reputation? To solve this mystery and restore the organization’s name, the Corpse King begins to reassemble the executives who once made Helheim the strongest—the “Eight Precepts”—and resumes his activities in the other world… while writhing in embarrassment.

First stop is the steel city of Gagiul. Save the struggling city and rescue the countess of dull colors who stands in peril.

“—Helheim, the operation begins now.”
