A thought occurs.
Patchy wants us to tell Marisa about that meeting, right? At some point, we're going to have to talk to her. If she really was flying in our general direction, I think now is the best time. There's a chance she's seen us, and trying to hide from her will make us look like we have something to hide, which will feed any existing belief that we're the ones responsible. We have nothing to hide, and have encountered all of Reimu, Sanae and Sakuya and have come away relatively unharmed - Sakuya didn't assault us at all, Sanae we surrendered our spellcards to and demonstrated trustworthiness, and Reimu hasn't come back from whatever trip we sent her on (I actually forget what we said to get her away). I think we might be able to talk our way out of fighting with Marisa, since literally every other problem-solver has had the chance to put us down and didn't, and that has to mean something. We may also get bonus points for going up to her of our own volition (and not firing upon her) instead of her having to track us down.
Since I'm going to bed right now and Draco has so far seemed to want to avoid Marisa entirely I'll just leave this idea out for people to think about instead of making that sort of unilateral decision, but I really do think we'd be better off confronting her instead of hiding from her.
