Yen Press has obtained the rights to publish the novel series in English, and it provides an enticing description of the story:
Heroism: a retribution reserved solely for the gravest wrongdoers. Those condemned to assume the mantle of a hero are compelled to confront the demon king’s horde on the treacherous frontline.

Perishing in battle merely ensures their revival, sentencing them to an eternal struggle. However, when their commander, found guilty of slaying a deity, encounters another divine being, the pact they forge possesses the potential to reshape the very fabric of our world.
