Won't you rise to the top by providing Ecchi material through Dungeon streaming? Sange, who started Dance streaming with the sole desire to become a Hero but saw no growth at all, and his younger sister Hanabi, who helps him, decide to do Dungeon streaming in the "Scud Dungeon" that suddenly appeared from an Isekai in the school city!! Sange charged into the Dungeon with high spirits, but he was granted the Skill "Chin-chi-N" by a Goddess. Due to this mysterious Skill, dark clouds loomed over the stream... or so it seemed, until the Goddess was attacked by a Monster and exposed herself in a lewd state, causing the number of connections to grow rapidly. Sange and Hanabi realized they could become popular through Ero streaming!! Can Sange provide "material" for the viewers through Dungeon streaming and make it to the top!!!?
