Well it's useful whenever the GHQ area has shut down for the day
Jokes aside, it is nice that everyone is collecting data. I won't be able to help a lot with that for a while since i am not in the BA yet, and this also means i cannot access all GHQ areas yet. Got two more girls i need to finish, and i will be stuck on the current until i can get her SR card since it is not available in normal gacha (rather not get an even lower chance later in the BA).
