Wakana remains insane, I see.
But I'm happy for Miyako - she wanted friends and to be part of an in-group, and her dreams have been realized.
Sadly for Ruruna, Wakana indeed remains insane and she let herself get swept along with it at just the wrong moment.
This title isn't deep enough that I expect the Hunter Nun to be a fakeout or anything, though if she is subverting the expected trope, I'd love it if she turned out to actually also be a vampire in disguise that had to be eliminated and not harem'd.
