a new anime i've been watchin for sumtime. its average at times. but really kiks arse wen its at its best. watched nine eps so far. and the 9th one was the best in my opinion. made this anime a must watch. getting better and better everytime. official description from anime news network:

"Okajima Rokuro is a Japanese businessman…in a town full of Japanese businessmen. His normal day consists of social drinking with clients and being kicked around by his bosses. He finally gets a break though, as he’s sent by his company to the tropical seas of Eastern China to deliver a disc…only his boat gets hijacked by a band of mercenaries hired to retrieve the disc. “Rock” (as he is newly dubbed by his captors) catches the interest of the only female merc “Levi” as she thinks he’s worth a ransom, taking him hostage. However, the disc that was stolen has a terrible secret that's unknown to Rock, which causes massive confusion and chaos for both him…and his kidnappers."

p.s this is pretty mature too...blood and gore..jus the way i like em :)
