Kazan Gunrō Ken

(華山群狼拳 Huashan Wolf Pack Fist)

A martial art technique used by the Fang Tribe (Kiba Ichizoku). The attackers pattern themselves after a wolf pack in an attempt to group-attack an opponent. This style has its basis in another Chinese martial arts called Xiàng Xíng Quán (象形拳, Shōkei Ken, "Imitation Fist"). In episode 26 of the anime series, there's a technique called Yōmetsu no Kata (妖滅の型, "Ghost Destruction Formation"), where the Fang Clansmen attack by surprise.
