Your favorite Vocaloids and UTAUloids are /for some reason/ in a distant world of monsters and dragons called Aiyo Ga.

The story focuses around the group of UTAUloids known as the Vippaloids as they try to figure out WHY they are there and how. And why the Vocaloids have decided they wanted to wipe out all the UTAUs with their newfound powers.

...While playing around with THEIR OWN newfound powers, of course.
