Hey, so i'm starting the game pretty much from the start.

i originally was rerolling my account, for nekomata, and just picking another server if i didn't get her.
However now i realise that i have a ton of accounts and they all give you a nekomata with the event selector.
One of my accounts has a vivian, should i just go with that, or should i just pick any account, choose nekomata and go on with the game?
i started playing again for this red girl, and just wanna accumulate rolls fast for her
