A camera crew ventures into dungeons to broadcast the impossible, treating monsters like breaking news and equipment failures like the real enemy. The show finds comedy in the collision between TV production logistics and high fantasy, a lighting rig fails mid-combat, sound gets eaten by echoes, the crew argues about angles while a basilisk approaches. It's a genre mashup that shouldn't work this well, grounding sword-and-sorcery adventure in the mundane panic of live broadcasting with no safety net.

Television has just been invented in a world still ruled by swords and sorcery, and now the cameras are turning toward dungeons that only adventurers have ever seen. Marda, an adventurer thrown out of his party, meets the reporter Syi and a broadcasting crew. Together they set out to air a live dungeon capture, the first of its kind. Along the way they battle endless monsters and keep running into equipment trouble. Competing against rival crews, they find out how much fun making television can be, and they also run into the ethical problems that come with mass media. The ONA mixes fantasy adventure with a story about the early days of broadcasting.
