Saiteihen de Agaku Boku wa, Isekai de Kibou ni Deau ~Jibun Dake no Youna Isekai ni Ikeru You ni Natta node Level wo Agete Minna wa Mikaeshimasu~

When a meteor shower streaked across the night sky, the world was changed forever. Dungeons teeming with bizarre monsters materialized across the globe, and every human gained the ability to view their own "status." With the days of peace at an end, delving into dungeons to hunt monsters became humanity's duty, and society now ranked each individual according to the power displayed on that status. Takashi Nakamura sits at the very bottom of this new order. Cursed with nothing but the lowest-ranked abilities, he endures constant ridicule from those around him. To scrape by, he hides away in the depths of the dungeons, working as a burden carrier for stronger adventurers and suffering through each grueling day in their shadow. But Takashi's fate begins to shift the moment he crosses paths with Argos, a B-rank monster lurking within a dungeon. He suddenly gains the power to freely travel to a game-like fantasy world all his own—a personal isekai where the experience points he earns flow directly back into his status in the real world. For the first time, the boy scorned as the weakest holds the means to level up and turn the tables on the world that looked down on him.
