Sitting at 150, and currently using my gift box as an alternative storage, so i could use another 80~100 more slots as my manyus will start expiring in a week. If you want to be efficient, or get screwed and don't get certain girls type (slice, i'm looking at you) or you dont hve clear targets for manyus so you end up holding some of them, then needed storage spce goes up pretty quickly ._.
