What did you think of it in the end? I was thinking of nominating it for the light novel club, but then I remembered the thing about the author expecting you to have read 雨のティアラ | L30?? already, which gave me pause…
I’ll personally probly still read it first anyway, just b/c I already started it, and I’m ambivalent about the horror-ish(?) seeming setting for 雨のティアラ (tho Konno-sensei does a decent job with horror/supernatural stuff in general)
