Hmm.. I'm not either such a big fan of the art... Ranma 1/2 and Inu Yasha were one of the first manga serieses I read and loved! I still haven't read all of them though.. I love Ryouga and Sesshoumaru

Hmm.. I've read Maison Ikkouku, which is one of the great examples how the art develops

I really liked that series, but if it hadn't been so hilarious I would have been tearing my hair out with the relationship problems

I've also read a few volumes of one pound Gospel (nice

)
Mermaid Saga (scary, touching...)
Lum Urusei Yatsura (fun and hilarious

and the Rumic World trilogy and Rumic theatre.. Hm... I hope I didn't foget anything... *thinks hard*
Altogether.. I really love the humour in her serieses

the art is plain and simple, and somehow different from other styles I've seen. Also it's hard to tell if her manga is shoujo or shonen.. Pretty much in between in my opinion
