estrela Driver: Kagayaki no Takuto... Well, it's a little mais on the friendship-side isntead of romance, but it's a really great, really funny series!
link Another great one is Dragon Crisis! It has an interesting plotline, complete with epic dragon fights, and it's romantic in a cute, funny way.
link I'll go for one more...
Romeo X Juliet. It's the perfect mix of AMAZING fighting and romance (obviously, since its Romeo and Juliet). But the plot's a little darker and there's mais storyline to it than the original story. ^_^ Also, lots of twists and mais characters to amor <3
link Hope you enjoy those! ^_^
