[The original book is being revised, so I'm uploading a new story here instead~~]
Ten years ago, humanity's strongest hero sealed the Demon King. Ten years later, with no Demon King to threaten the human world, heroes were no longer needed, and people gradually forgot about them.
As the heir to a hero's legacy, young Gio Scarth saw that his family couldn't even afford the rent. He decided to gather his childhood friend and fellow hero's heir, Iris Landemir, and head to the dungeon to release the Demon King. Then they could bring out a hero to defeat the Demon King and revive the hero clan!
After the two of them disguised themselves as monsters and set up a base in the dungeon, Gio's sense of justice led him to save the Demon King's heir, even though it would help him achieve his goal!?
The dungeon adventure begins: an unscrupulous would-be hero seeking work and a somewhat airheaded would-be Demon King seeking to revive her legacy!
