So, takeaways from this chapter:
This sort of says that Kiyoharu produces both the regular negative energy, which people chosen to be magical girls produce a lot of (implied to be something like a "female soul" if the dialogue in the Planet chapters are anything to go off of), and the "male" minus energy. Since none of the admins except Nana knew about the minus energy thing, Hachi enlisted Kiyoharu just because she produced a lot of negative energy like every other chosen magical girl, to feed into energy for Tempest.
But also:
Kiyoharu has been presenting as female, calling herself a girl and genuinely believing it, and wearing girl clothes for at least the current school year up until now (several months), but she still counts as more "male" than Kaname, who just got a dick up his ass? Kayo literally was just a regular girl for 14+ years of her life but she grows a dick and she's suddenly more "male" than Kaname? Like there is some dumb shit that happens in MSS but this might honestly might be the dumbest shit that's happened yet. Like, the "they're actually twins" reveal had foreshadowing going into it for a long time, this just comes out of nowhere and makes no logical sense.
Also KiyoKosa is still the best ship.
