Ojousama-kei Teihen Dungeon Haishinsha, Meiwaku-kei wo Bokottara Bazutte Densetsu ni Nattemasu wa!?

Set a few years after mysterious dungeons suddenly began appearing across the modern world, the story follows Karin Yamada, a young woman attempting to make her mark as a "dungeon streamer"—a newly emerging type of content creator who broadcasts live expeditions into these perilous underground labyrinths. To stand out in a crowded digital landscape, Karin has carefully crafted an elegant online persona modeled after a refined, wealthy aristocrat. Despite her dedication to the character, reality paints a far grimmer picture. With zero viewers and a mere three subscribers, she remains hopelessly obscure, leaving her deeply frustrated and depressed over her complete lack of success. Her fortunes change dramatically during a routine broadcast when she stumbles upon another adventurer attempting to cause a massive explosion inside the dungeon purely to stir up controversy and generate views. Without hesitation, Karin leaps into action, swiftly subduing the troublemaker with a decisive physical beatdown. Unbeknownst to her, the reckless adventurer was simultaneously streaming to a massive audience. Thousands of viewers watched in real time as Karin thoroughly defeated and lectured the instigator. The spectacular footage spreads like wildfire, catapulting the perpetually struggling streamer into overnight internet fame and transforming her from a forgotten nobody into a viral legend.
