AND PEOPLE SAY THAT THE KAGAMINE TWINS BEING SHIPPED TOGETHER IS WORSE THAN THIS?
Oh come on. Plus, there was this one Greek myth I read about when we researched them a few years ago. The first humans had four arms, four legs, two heads, all of that. But Zeus decided that they would be too powerful and split them apart, and the humans were like they are now, with two arms, two legs, and one head. But they still only had one soul shared between the two split halves. These people were called soulmates, people who were destined to be together, and every human alive would spend their life looking for their soulmate.
Gee, I wonder who shares a soul in the Vocaloid world, hmm?
