Aoki Umi no Torawarehime ("Captive Princess of the Blue Sea") by Yuki Ayumura 2 volumes - completed
Princess Matsurika was abducted by a pirate with a purpose of using her as a sacrifice. I first saw a wallpaper of this on Otome Comic High and I was drawn to it. But I dismissed it as non-reverse harem. (If anyone was able to save all the wallpapers there, please, please send me the links!) The story is sweet mixed with action. But I felt it was lacking. I'm not sure if it needed more romance or more feelings or more action. But I like the fact that the main guy surprised me with being out-of-character at times. The rest of the crew and even the villain are also all beautifully drawn so I kind of wanted more interaction from them too. But alas it all ends in just two volumes.
