Yeah the illustrations are a great part of the novels, really like Shiro Amano's take on the characters. The Larxene on the back cover of CoM is probably one of my favorite takes on her and their Aqua is also super cute.It's before, then it'll have MoM and the Zoo-Keys (Foretellers) in them? If so then I'll certainly want that one. One thing I've loved about the novel's is Shiro Amano's illustrations in them too. I love that cartoony style and want to see them in it.
The KH3 novels and mangas will likely be split up here, which I'm honestly okay with. Yeah, I'd prefer the mega novels but the small ones aren't bad either. I'm hoping they both have ReMind content in them too.
I imagine that ReMind would be included in both Novels and Manga, after all most of ReMinds additions are in the later part of the story, which neither is close to yet.
