A day of watching your favourite VTubers becomes your worst nightmare(?). Something seems a little different about the streamers you love, though... almost dark and sadistic. Rather than threatening to step on you, things become more sinister as you struggle to help them conquer your current world... Can you successfully help the girls and survive?

PrismTales.Alt is project multiseries of alternative lore based on Prism Project's Gen 4 talents: Naki Kamizuki, Sara Nagare and Non Anon. This visual novel game is created as an introduction to future lore series using different mediums.
