Not Just a Program (Vocaloid FanFiction)

The Vocaloids have lived in their huge mansion their entire lives. Why a mansion? If all of them lived in a house, they wouldn't all fit. And they wouldn't be able to do their work. What work, you may ask? They help the humans with problems before they're too major. But what happens when there's a virus going around the world while, at the same time, creatures are running free, and the Vocaloids are scattered across the world?
