Thirty years have passed since dungeons began appearing in Japan.

Tokyo was devastated by these dungeons, and as a result, both public safety and the economy had severely deteriorated.

Amato Sakurazaka, who had lost his parents and lived alone with his younger sister, was struggling to find work to pay for his sister's tuition but couldn't secure a job offer.

One day, he suddenly encountered a dragon in the middle of a residential area.

Helpless, Amato was on the verge of being killed by the dragon, but this incident triggered his awakening to memories of his past life.

Remembering that he was a sorcerer from another world, he pummeled the dragon and immediately began his career as a subjugator, conquering dungeons.
