Fushigi Neko no Kyuu-chan is a thirty-part webcomic by a Japanese artist named にとりささみ. It's cute and weird, and both those things make it a joy to read. Situations don't play out in normal ways and you'll need your Japanese to understand what's going on, to a certain extent. For example:
The Japanese language doesn't stray too far past intermediate at parts, and you have to be able to read a font that mimics handwriting. It's a bite-sized read that may just add a few things to your Japanese knowledge pool. At least it'll add a sound effect or two!
