you were a new vocaloid, so you would be a new resident in each sekai, the third sekai would be the sekai of the group VIVID BAD SQUAD, street sekai

you woke up standing on a street, it was pretty, you see a girl leaning against the wall with her arms crossed, looking at you, she has short Brown hair and Brown eyes.

– hi, You must be the new resident, right? I'm MEIKO, come with me, i'll show you the others. – she says, offering a hand to you.
