Oh, the lackeys actually took part in this.
I thought they're just trying to "survive" by latching to Hozue, but they're actually worse. They're her fucking enabler, albeit unintentionally.
I'll give them the benefit of doubt, like maybe they feel suffocated having to suck up to Koharu, but goddamn, they don't need to denounce her right in the middle of the class, man.
And their existence as lackeys also the one that keeps Hozue alpha bs going, because she took them as the tangible result that what she's doing is working.
Without them clinging, she'd prolly run out of steam sooner and maybe, just maybe, reconciled with Koharu before Midschool end.
But with them existing, reconciling would just destroy everything that she built for. Sunk cost fallacy, really.
