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 boy standing in front of you, he has blonde hair tied in a little ponytail and blue eyes.

– Hi! You must be the new resident, right? I am Len! Come with me in the crase cafe, the others are all there! – says the boy, offering a hand.
