So... now that I finally got my hands on the Japanese books *cuddles serena_daragon*, I was able to do some decent icons. Pretty plain ones, I'm not an adept of messed-up colours and text that cannot be read, but still. They are free to use, so help yourselves to anything you might like.
I'm working on a series using the character images at the beginning of the novels, but those might take a bit since I don't know what I want to do with them, theme and colour-wise.
