As expected, the StuCo takes one final infraction as an excuse to shut the Hero Club down. Locking up their clubroom and banning them from helping people inside or outside school, on pain of expulsion. That infraction? Allowing a non-student in “Setsuna Kirito” on school grounds during the festival.
Mizuki might’ve had a chance to clear things up, but to do so would’ve meant breaking her promise to keep Futaba’s alter-ego a secret. Besides, they would have found another excuse anyway. With the club shuttered, Sekiya is attacked by an unknown entity, while a rash of thefts are perpetrated at school.
Mysterious thefts and assaults aside, killing the Hero Club was extremely short-sighted (which I guess becomes the StuCo, all of whom wear glasses): all of the school clubs they helped out relied on them being around, and now they’re all in big pinches.
As their normie emissary, Mizuki is the one who has to hear from these parties about how unfortunate it is, but while there’s talk of them giving the StuCo a piece of their minds, that doesn’t take place here, and the other Hero Club members mostly go off and do their own thing, albiet badly because they’re depressed about losing their meeting place and mandate.
It’s just as bad outside of school, as Mizuki has to turn down a girl who loved Tomoki’s Sora-chan performance and wants him for another one. The elderly folks who the Hero Club helped blame themselves for relying too much and getting them in trouble, which Mizuki has to reassure them isn’t the case.
Whether in or outside of school, the Hero Club was a vital resource whose importance belied the eccentricity of its members. Disbanding them left a huge void in the fabric of both school and community. After partnering with Mizuki and a member drama club to help out the Sora-chan girl, Nanako assures Mizuki that together they’ll find a way to rescue the Hero Club from the StuCo unjust and reckless judgment.
They certainly have public opinion in their favor. As for the mysterious culprit of the assault and thefts, that’s something the StuCo seems incpable of solving. They may have no choice but to rely on the rule-breaking weirdos they loathe.
