My Vtuber System Wants Me to Stream in a Dungeon?!

Another day, another poor bastard gets isekai’d. Truck-kun claimed another victim. Parita Kestrel, an aspiring female streamer, got transmigrated into a fantasy world because of a certain truck’s delivery service. Upon her arrival in this new land, a strange system appeared, offering her a chance at something better, but at a cost. She had to become a Vtuber. Even though she was in a fantasy world devoid of technology like smartphones and computers, the system forced her to stream, and she couldn’t tell others that she was a Vtuber. After raiding a dungeon, she was then forced to perform a live concert...? What is she, a horse girl?! No, just a Vtuber, a gentle and harmless idol who, by accident, killed a dragon with an overhead suplex.
