can anybody recommend a good action/romance anime?

Ga-Rei Zero

Kagura and Yomi are two girls who have a bond that cannot be broken. While once they fought side by side against the supernatural forces that threaten the planet, fate had something different in store for these star-crossed companions. Yet to understand the present, one must first experience the past – a time before Kagura’s involvement with the Supernatural Disaster Prevention Agency. Always cheery and good-natured to a fault, the young Kagura first meets Yomi when she is invited into her home. Over time, the two battle malicious spirits and grow closer together – but soon, more terrifying foes begin to reveal themselves. A swarm of glowing blue butterflies and a mysterious stone are harbingers of darker things to come, and one thing’s for sure: Kagura and Yomi will never be the same.

Angel Beats! (More of the opposite sex friend until the end when it becomes more of a romance show)

Death and reincarnation are inescapable, but what happens in between? Without warning and without his memories, a boy who only recalls his last name - Otonashi - wakes up next to a girl named Yuri who offers him a gun and tells him to shoot an angel. Assuming it must be a misunderstanding, Otonashi is then almost killed by the angel and is drawn into Yuri's army to battle to delay the beginning of his next life. Immortality is within reach, but if Otonashi remembers how he died, will he keep fighting or allow himself to vanish?

Kampfer

Natsuru used to be a typical student with a crush on Kaede, one of the school idols, until one day he awakens to discover that he’s turned into a busty girl! Having been chosen to become a Kampfer by the mysterious Moderators, Natsuru is now required to not only fight other Kampfers, but also to transform into a girl while doing so. Aided by a stuffed tiger, Natsuru must now battle it out with other boobalicious babes and continue to try to get close to Kaede – a task that will now be easier as she’s fallen for Natsuru’s female form! Can Natsuru keep his secret safe while maintaining his double life?

Rosario + Vampire

Fifteen-year-old Tsukune Aono is average in every way; he has no hobbies, less-than-stellar grades and he's even flunked his high school entrance exam. His parents have managed to enroll him in a school, but it's no ordinary school! Tsukune will be attending the Youkai Academy, a place where monsters learn how to co-exist with humans! As the werewolves, vampires, witches and other monsters are required to retain their human forms, Tsukune - the lone human - is able to avoid their bloodthirsty gazes. However, he quickly attracts the attention of a number of devilish beauties including the vampire Moka, a busty succubus and even a young witch! It seems Tsukune's average life isn't so average anymore!

Ga-Rei Zero's not exactly a "romance" show but it has some romance in it, more of a dark drama/action show (don't watch if you don't like 17+ shows). The other 3 are light-hearted Action/Romantic Comedies (Rosy and Kampfer are also Harem/Ecchi).

The Place Promised in Our Early Days. I remember just loving the visuals. It has action, but more romance I think...

You should watch One Piece. When i first heard of it, it didnt sound very good but now I really like it and I am hooked. I dont know if it has that much romance that you want, but it does have a lot of action.

Kannazuki no Miko. (action and romance) (yuri)

Revolutionary Girl Utena. (action and some romance)

Possibly Sailor Moon? Don't know your taste though... (action and romance)

Strawberry Panic (romance) (yuri)

Vampire Knight is awesome too.
