Magical Girl Gacha?

Probably not. The rate-up servants aren’t that great / are pretty niche, and it’s too late for the event drop CEs to make a difference in farming. I’d save your quartz for a better banner.

The loli banner isnt good imo. The 5*s are almost useless against anything without class advantage and the 4*s are kind of okay. I think the only reason to summon is for Illya and/or to reunite the Emiya family

Jail is just a room oniichan
