I swear, Kosame's pose with the hat feels like a reference to the manga Domo.
Also @EvelynIsGone it's been established that men using sticks harms the King. So Kayo probably plans to use it to change her own sex to hurt the King as a back-up plan.
@fennec But... it's implied biological sex doesn't matter, because Kiyoharu isn't brought up at all as an option for harming the King. It also wouldn't make sense because the existence of the Necktie Stick would inherently mean that King would be harmed from it.
What!! the Shitty Bowl cut hero is here..
well I can approve this is the most ambitious crossover *LoL
it's been long since I stopped trying to predict this manga or the sister manga, and I glad to do that or it'll blown my mind
