What’s the Story About?
The original light novel series, [Hihō] Ojōsamakei Teihen Dungeon Haishinsha, Haishin Kiriwasure ni Kizukazu Dōgyōsha o Bokotteshimau ([RIP] A D-Tier Pampered Lady-Type Dungeon Streamer Forgets to End Her Stream and Beats Up a Colleague), is written by Hirotaka Akagi and illustrated by Kitsune Fuku. The story is set in a modern world where dungeons have begun to appear. Karin Yamada, the main character, is a “dungeon streamer” who broadcasts her explorations of these dungeons to a small audience.
Karin has adopted the persona of a refined, upper-class lady, but in reality, she struggles with low viewership and a mere three subscribers. Discouraged by her lack of success, her life takes an unexpected turn when she encounters a fellow adventurer attempting to grief a dungeon for views. Driven by a sense of justice, Karin intervenes and beats up the troublemaker, unaware that the entire incident is being live-streamed to a large audience. This act of heroism, caught on camera, catapults her to overnight fame and transforms her into an internet sensation.
Karin Yamada: From Obscurity to Internet Fame
Karin’s journey from an unknown streamer to a viral legend is a central theme of the manga. The story explores how her actions, initially driven by frustration and a desire to do what’s right, lead to unforeseen consequences and a complete transformation of her online presence.
The World of Dungeon Streaming
The manga introduces the concept of “dungeon streamers,” a profession that blends gaming, exploration, and live broadcasting. This unique setting allows for a blend of fantasy and modern-day elements, creating a humorous and engaging narrative.
