Bloody hell. I can't seem to edit my previous post...wth? Well, I forgot to close off two codes, so its driving me mad.
Binbougami ga! ; Hilarious, filled with action/comedy and very slight "romance"
Fairy Tail ; Action/Adventure/Comedy shounen, with very slight hints of romance, but not actually any.
Claymore ; It takes some time to get used to the art, but overall it's very good. Contains a good amount of violence and blood though.
xxxHOLiC ; It's more on the mysterious/supernatural side and it doesn't have a lot of action, but it's a very good read.
Superior ; It's a good action/adventure manga that has some romance in it.
Samurai High School ; Pretty funny and interesting manga with some action. No romance though iirc.
Well...I hope that's a good start :P
