Jin's credo was to do anything for his adorable younger sister, despite their age gap, and so he accompanied her as her cameraman for her dungeon-conquering streams.

The moment the stream began, the two fell into a warp trap and were teleported to the 95th floor, where S-rank monsters appear.

Just as every viewer resigned themselves to their deaths, Jin had to get serious against a Black Dragon to protect his sister.

His overwhelming display of power, single-handedly dominating a Black Dragon that no one had ever managed to defeat, was immediately spread across the internet, and Jin went viral, becoming incredibly popular...

Collaborating with various famous streamers, Jin became even more famous.
