That being said, I think it's highly likely that they're tied to a battle facility. The fact that there even is a seperate, earnable currency implies that there's both a unique way to earn them that's somehow different from LP/money, and more unique uses for them. It'd be extremely bizarre to introduce a THIRD currency for no real reason. Furthermore, the fact that the Indigo Disk is tied to post game, and the fact that the school is a school with it's own league fits this. The generic NPC datamines, alongside there being a new ribbon also fit with this. I think it's likely that the Blueberry E4 will be re-challenge-able in a Battle Tower style format, and you can grind and earn BP this way.
