I just wonder, on this kind of gacha event, remaning currency after the event is turned into gold coins or not? I don't remember. It worth to do some extra event stage after completing gacha or not at all?
So, event is done for me. Time to do some reissue for hard-drug chan.
Seems like not, any remaining currency can't be traded. Whether it's letter or book.
