異世界帰りの勇者は、ダンジョンが出現した現実世界で、インフルエンサーになって金を稼ぎます！

An ordinary-looking junior high school student, Ryoji Furuya, had a secret. During spring break before his third year of junior high, he was suddenly summoned to another world. After ten years of hardship, he defeated the Demon King and returned to his original world.

Moreover, Ryoji didn’t age at all and returned at the exact time he was summoned to the other world. However, right after returning, his parents died in an accident. He had conflicts with relatives at the funeral, and suddenly, familiar dungeons appeared all over the world.

The world changed drastically as energy, metals, and essential materials for convenient living could only be obtained from these dungeons. A small number of people with “adventurer traits” began to level up inside the dungeons, earning significant achievements and making money.

Due to the effects of being active in two worlds, Ryoji had adventurer traits but no displayed job and his level remained at 1. Abandoned by his childhood friend who had excellent adventurer qualities, Ryoji started his activities at his own pace, earning a large amount of money and becoming an influencer.

With no particular life goal, where will Ryoji’s tomorrow lead him?
