they bedder do bring us bond crystals. i didn't refill my NG today, and i don't think i will in near future, looks like i already lose interesst in this game... so if there won't be any new thinks like those bond crystals, or stuff like the specials the DMM version offers, e.g. :
1.5x leader experience earned
2x gold earned on 8/26 - 8/28
A daily, free Premium Gacha is available to roll 1x until 9/4
30% stamina cut for Aqua Shadow, Chapter 3 stages
30% stamina cut for Character Quests
i don't think i will spend any more money or even stick any longer with this game. i'm at this point again where collecting girls isn't enough anymore.
