@Whiterunight bruh this is how the entire manga has gone and will keep going, fun fluff with some progress here and there, that's how it's always been and will be.
Let's see... Kishi-san first appeared in bloody chapter 8 i believe, and since that was back when the chapters were only a couple pages long, that might very well have been the first or second issue of the manga. But she never had her own episode which is probably why not everyone noticed her. She's a part of Yamai's group of friends, but so is Onigashima, so i'm hoping she's a good girl too. She once smacked Yamai and dragged her away when she was a nuisance, so she probably is a good girl :). And she's also a part of the Komi Imperial Guard . That's all i can remember at the moment.
