Manga:
Le Portrait de Petit Cossette, Chapters 1-10
Finished reading the manga version and I have to say, very bloody and creepy. D: The ending I'm kind of having a grip over as I thought everything just went so fast. XD
Black Cat, Chapters 1-37
Been reading it the last few days. Yeah, the anime and manga versions are totally different. :O So far I'm liking the manga version better, especially since Sven and Train's interaction is much funnier and less stuffy than in the anime.
Anime:
FLCL, episodes 1-3
Been hearing great things about the anime, and I have to say I love it a lot. Already mentioned in another thread how I like the music, the art style, and the characters. Also, it's quite funny even though there are a few breaking the fourth wall moments here and there.
