Sooo... i have no idea where the author is going with Yuuhi's arc. Still looks like Rio's testing Yuuhi's friends if they're serious with their friendship. Would make sense since all previous character background stories were solved through friendship. So far, Rio did nothing too bad after...
Shiramine is tsundere, all right, but that attitude of Kurosawa in this chapter is even bitchier than anything Shiramine showed us so far. And what the F did she bit her for? Shiramine sure is a masochist for liking her. 👀
