Chapter 1: First arrival

third story yay :D I wanted to make this story cause I thought of a story idea of Hololive and Nijisanji had a crossover with Undertale

Hololive just had a New member recently more specifically Hololive ID Hiroshi Kenzi at the same time Nijisanji also had a new member Frisk but here's the twist Hiroshi and Frisk know each other as they met before at strange world called "The Underground" how will Hiroshi and Frisk tell their new Vtuber Friends? and how will they react?
