It isn't too much of a surprise that CSG was the root behind everything. As the one that Adachi is talking to has the Fairy Tale Card. So, while we don't know who that person is, he must have received that power from CSG. So the power dynamic was CSG → Fairy Tale Card Holder → Adachi & Murakami. Now it seems for those two they get assignments & they have to follow for those assignments. More than likely CSG wants things done very particularly. Sadly for Adachi she is getting involved just to help her mother.
The other big part is Momo. The curse is now taking root. Which we now see that Vamola can't see her. That is a terrifying thing. It does feel like we are going to get into a situation where Okarun will be the last person to be able to see Momo, but that is when he will fix the curse. It would amplify the romance between the two, which is the core foundation of the series.
