Nanto Koshu Ken
Shin's style. Nanto Koshū Ken (南斗孤鷲拳, South Dipper Lone Eagle Fist) is an orthodox style of Nanto Seiken. It focuses on stabbing and thrusting attacks, seemingly being most useful through direct contact. The style also seems to use flying kicks, as seen during a flashback in both the manga and anime, and as the Nanto Gokuto Ken/Nanto Gokusatsu Ken Ougi (special technique) which uses an air pressure wave/ki to cut and disable the opponent. This branch of the Nanto Seiken was originally unnamed in the original manga and anime. The designation Nanto Koshū Ken was first used in the 1986 publication Hokuto no Ken Special: All About the Man and has been used in every official Hokuto no Ken source since then. Shin mentions its name for the first time on-screen in the 2007 OVA Yuria Den.
