Posting updates about me tiering because yes:

No white day Tomoe AND Tomoe is an event card in the backstage pass 4 meaning no powerful 4* Tomoe which is what I expected... But roughly 87 boosts later i have 100k!!! I'm trying to get 150k for now and then doing circa 50k a day ( which is a lot... ). Poorly it'll take 30 boosts per day which is pretty much lots of stars and boosts i need... And i also have school so it's hard spreading out everything, but i will try!!
