Insano Steve says: Teenage Yakuza Riki Fudoh has his underage crime syndicate running like clockwork. His team features child assassins and women who shoot vaginal blowgun darts and the usual assortment of misfits. But to claim control of Kyushu island, he must off his father who is the leader of the controlling Yakuza. Fortunately, this can only be achieved violently with as much bloodshed as possible.
Based on a Manga. Gratuitous beheadings, acid burning and hermaphrodites (God bless those sexually gifted freaks) are always appreciated.
