TS = Tsu Futaba | Drummer + Leader

NA = Nanami/Nami Hiromatsu | Bassist

RU = Rui/Ruirui

TK = Kirigaya

So, this was data-mined from JPDori files

Umm looks like it's almost guaranteed that we are getting at least one new band this Anniversary. Also, they have voices for after live shows which helps prove that we're guaranteed to get a new band in Garupa.

Ooh boy don't know how to feel~

On one hand, new members! On the other hand, you have less of a chance to get your best girl in gacha... Of course there's more positives/negatives (you can always find more) but I won't list them because that would be talking too much lol...

Anyways...

If you want to find where I got this info find it on this twitter post
