It doesn't surprise me that doa114christ couldn't stop talking about Noblesse or just stop talking in general. She's quite chatty. (And pleasantly so!) I hope you're liking Noblesse so far. When I first found it, I read the whole thing over two days, but there was a considerably lower number of chapters back then. Anyway, I'm hooked.
Noblesse S is a light novel that focuses mostly on the school/personal aspects of the characters' lives. It used to be for sale, but it was offered for free a few months ago so now I'm part of a group that translates it into English. That's honestly all I know. I've only read the first chapter, haha!
