Haou Airen ("Supreme King's Mistress") 9 volumes-complete
Kurumi is taken by Hakuron to the world of Mafia in Hongkong. I've already read 5-6 of Mayu Shinjo's works so I was bored with the first half considering Shinjo's characters looks the same, Kurumi falling in love with the guy way too soon (she's too easy) and the same 'Love Celeb' interruptions (BTW Hakuron had a cameo there but I didnt know him then). The turning point of the story is at the middle part then it was like "100% Perfect Girl" all over again. Same character flaws but way, way, way more smuttier and bloodier. All the guys that are after are all anti-heroes as well although one or two seems to have feelings but others were only after her body. :S For mature readers only. Thanks to Tartza for the tip!
