In a modern world where dungeons have appeared and professional exploration is a recognized career, a young man named Yozakura Shishio works as a dungeon explorer. His ordinary life takes a sharp turn when his favorite VTuber casually mentions wanting to eat food made from dungeon ingredients. Determined to make this wish a reality, Shishio realizes that a regular fan has no way to approach a popular online idol. His solution is to become a VTuber himself.

Adopting the persona of a super hunter named Yamanu Boton, Shishio begins streaming his dungeon adventures with a unique twist. He uses his exceptional skills and cheat items to gather rare, dangerous, and often bizarre dungeon ingredients, which he then cooks into elaborate gourmet meals on stream. The combination of high-stakes exploration and mouth-watering cooking quickly captures the audience's attention, and his channel rapidly gains fame and goes viral.

The central conflict emerges from this very success. Shishio's ultimate dream is to collaborate with his favorite VTuber and personally serve them a dungeon-cooked meal. However, his unconventional and flamboyant methods of obtaining and preparing ingredients, coupled with the chaos of sudden internet fame, leads to a massive online backlash. What began as a pure act of devotion spirals into an unexpected conflagration of controversy, forcing Shishio to navigate the volatile world of streaming, public opinion, and dungeon dangers all at once. The story follows his journey as he continues to pursue his goal, using his culinary and combat prowess, while dealing with the consequences of becoming an overnight sensation.
