VY2 Yuuma

VY2 Yuuma, or simply Yuuma, is a member (not exactly child) of the Vocaloid Household. Although he isn’t as popular as his Vocaloid companions, he still enjoys to be there with his friends. He is currently the fiancé of IA.

Ok so according to fanfics, he was a Vocaloid who was cold and mean and a bitch to almost everyone but I guess he isn't as much anymore. Yes, he did act like this at one point in his life but Mizki being the "helpful" sister she was helped him to stop being such a cold bitch to everyone. i really don't know why this is here it's just a headcanon i guess

Relationships
IA - He met IA in the household, meeting just as bored friends. As they started to hang out more, both developed feelings for each other, eventually confessing their feelings. Soon, they became a loving couple. Months later, Yuuma proposed to IA, making them an engaged couple.

Tei - The only "relationship" he has with her is the fake marriage that Ruko "blessed," tattooing a ring around Yuuma's finger. And oh God does he have Tei PTSD now- But I mean, sometimes he's fine with her.

Yohio - Like IA, they sort of met in the household. Since they both like to drink, they sort of became drinking buddies if Fukase wasn't around.

ZOLA Project (Yuu, Kyo, Wil) - He met them in his private household for the Vocaloids he prefers to have there. He gets along well with them, honestly.

Gakupo - literally just bros

VY1 Mizki - He gets along really well with her, being his sister (in this universe). They were meant to be partners, but I guess they just kinda are brother and sister, now-

History cause fuck it
Created in April of 2011, VY2 Yuuma had the role of being the male counterpart to VY1 Mizki, his partner. Later on, he considered her to be his sister, for they had similar tastes and interests and stuff like that, just like siblings (you can't forget sibling rivalry, either).
