Are the events of other Taimanin games canon to this game? I was just eyeing Kurenai to buy her (I already have Felicia)
I was wondering if Felicia helping Kurenai lactate during sex, counts as having happened already in this game.

Also I would really love to know how to get more of these bat coins, they seem pretty important but I can't find them on my inventory, can't find more info about them from the ? (it just tells me the UR rates) and can't find them given away on any of the prizes/lists I've gotten before. Where do they come from?
