Yes, there is direct involvement from Madokami into the story, but how that involvement happens... it happens in chapter 10, we are very close at this point, so I will not say anything about that.
It should also be noted, the playable Nagisa in MagiReco is actually Cycles Nagisa, that is, she is the Nagisa from the original series' universe, and in fact an envoy of the Law of Cycles, Nagisa from the MagiReco universe still became a Witch, and Charlotte proves herself to be the most powerful Witch ever fought short of Walpurgis herself, her hunger-based nature causing her familiars to rapidly develop into full Witches, creating dozens upon dozens of Charlotte copies, which both Kamihama Cheese Panic and Mirror World Chocolatier events revolve around fighting, the later of which ends with Mami fighting Charlotte Prime, that is, the Charlotte that actually was Nagisa, to save Cycles Nagisa who had become trapped in Charlotte's labyrinth, and winning the fight this time.
Also on an unrelated note, why doesn't Touka and Nemu use their super intelligence to do something, like make magical girl science babies.
...they are 11, I don't think they are anywhere near the point where they would start thinking about what building a family would even entail, even in the context of super intelligence, some aspects of life only come with actual maturity.
Though they did end up with a daughter regardless, even if that's much, much less of what you meant...
