• Unlike the other Vocaloids, who were at one point human before becoming Vocaloids, Yuuma and Mizki were artificially created, so neither of them age and while they still need to sleep and eat, they can survive longer without doing either of those things. It's still not pleasant for them, though
• Since they're sexless, they don't care about what pronouns are used for them
• Most people call them they or he though
• Because they have no official design, Yuuma and Mizki can both change their appearances however they please, though Yuuma prefers to stay in their 66 roro design
• Bi
• Is secretly really insecure and constantly making small changes to their appearance to make themselves look better
• Has fangs because they thought it looked cool
• When they're in sword form, they obviously can't move or talk, but if someone holds them, then they can communicate telepathically
• Dating Mizki
• Used to have a crush on Hio, then IA, then Luka
• Is rivals with Gakupo
• Only went by VY2 for a little while before Kaito decided that they deserved a real name and started calling them Yuuma
• Since they were artificially created, it took them a while to develop emotions and a personality
• Sometimes shapeshifts into the other Vocaloids to prank them
