Sora Ueno is a high school student who carries the memories of a past life as a powerful onmyoji in the Heian era. Reborn in the modern day, he attempts to make a name for himself as a dungeon streamer, a popular online genre where adventurers broadcast their explorations of monster-filled labyrinths. The major obstacle he faces is that in the current age, onmyoji are dismissed as fraudulent mystics, a prejudice that leaves his own streams stuck at zero viewers.

Everything changes when, during a live broadcast, Sora intervenes to save a massively popular and glamorous streamer from a deadly threat. The dramatic rescue clip goes insanely viral overnight, catapulting Sora into the spotlight. The public is not only captivated by the incident but is also shocked to discover that his onmyoji powers are not tricks; they are overwhelmingly real and far more potent than anyone could have imagined. This revelation marks the true beginning of Sora's legendary dungeon-streaming career, where each subsequent broadcast becomes a viral sensation as he accidentally showcases super-rare cursed artifacts and demonstrates abilities that blow all expectations out of the water. The setting is a contemporary world where dungeon exploration is a spectator sport, blending modern streaming culture with ancient supernatural arts. The primary narrative arc follows Sora’s unexpected rise from a zero-viewer outcast to a legendary figure, driven by the viral nature of his rescues and the raw power of his Heian-era magic.
