Nanto Koshu Ken

(南斗孤鷲拳, South Dipper Lone Eagle Fist): An orthodox style of Nanto Seiken practiced by Shin, which uses stabbing/thrusting attacks, seemingly most dangerous in close quarters. It also has the ability to perform flying kicks, as shown in flashbacks in both the manga and anime, and the Nanto Gokuto Ken/Nanto Gokusatsu Ken attack, which uses air pressure to disable an opponent's limbs.

This branch of the Nanto Seiken was originally unnamed in the 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 announces its name for the first time in the video game Hokuto no Ken: Shinpan no Sōsōsei Kengō Retsuden.

Techniques

㊙ = An "Ōgi" (奥義 secret) technique.

Shin's Nanto Koshu Ken style
	Dokuja Senketsu (Venomous Snake Drilling Hole): Ducking low for a moment, Shin spins himself upright to pierce his hand into his enemy's torso. He seems to pump a golden aura into them and they break apart seconds later. Cannot be blocked.
	Gokuto Ken (南斗獄屠拳, South Dipper Hell Slaughter Fist ): A flying kick which maims the enemy by slicing the tendons in their arms and legs.
	Gyakushi Sō (南斗虐指葬, South Dipper Cruel Finger Burial): a bloody stab to the chest.
	Hakuen Tenshō (南斗白燕転翔, South Dipper White Swallow Revolving Soar): a backward/forward somersault.
	Hakuha Zan (南斗迫破斬, South Dipper Force Breaking Slash): an upward slash attack.
	Hakushu Koshi (White Condor Crimson Lips) ㊙: Shin surrounds one of his hands in a golden aura. It straightens as though it were a blade and Shin uses the same enhanced hand for a forward thrust.
	Hien Zan (南斗飛燕斬, South Dipper Flying Swallow Slash): A powerful flying kick used by Shin against his rebelling thugs in Episode 21 of the anime series.
	Hiryū Ken (南斗飛竜拳, South Dipper Flying Dragon Fist) ㊙: A series of rapid punches used by Shin against General Barcom in episode 21 of the TV series to counter a technique that gives Barcom the strength of steel. The result of the attack makes his enemy crack all over like rock before Shin deals a finishing blow. It is modeled on Kenshiro's own Hokuto Hyakuretsu Dan from the second chapter of the Hokuto no Ken manga pilot, which in turn was the prototype for Kenshiro's trademark technique, the Hokuto Hyakurestsu Ken.
	Kaketshu Juji So (South Dipper Bloody Cross Burial) ㊙: Shin hovers high into the air. He slices the ground below him twice, forming a destructive cross shaped aura beneath him.
	Moshu Shee (South Dipper Brutal Vulture Dive): Launching his foes into the air with a dynamic flip kick, Shin stays aerial and rapidly stabs several foes below him with hands. He ends the chain by twirling in the air, slicing foes within the range of his fingertips.
	Mumyo Fusatsu Jin (Avidya Measured Killing Column): Shin powers up before he smashes the ground with his fist. At first, it seems like nothing happens. Five seconds later, a large cross shaped aura grows from the impact of his fist and emits a geyser of energy. Those within the cross's glow are damaged. Cannot be blocked.
	Raishin Shō (南斗雷震掌, South Dipper Thunder Tremor Palm): Shin charges his hand and stabs it into the floor, causing a geyser of energy to explode up at the enemy.
	Renki Tsuha (South Dipper Vibrant Wave): Shin stands upright and waves one of his hands to his front. His hand traces a beam of energy across the ground, which erupts into an explosion moments later. Enemies hit by the attack will additionally be entrapped in a yellow aura for Shin to explode on whim.
	Ryūhashi Dan (南斗流羽矢弾, South Dipper Flowing Feather Bullet): taken from the scene in the manga, Shin fires a piercing feather at the enemy.
	Sei Zan So (South Dipper Misery Edge Claw); Performs a mighty swipe of his fingers in front of him, cutting apart those within his range.
	Senju Zan (南斗千手斬, South Dipper Thousand Hand Slash): a rapid stabbing attack.
	Senkyaku Sō (南斗旋脚葬, South Dipper Spinning Kick Burial): a sweeping leg kick.
	Senshi Kanshu (South Dipper Thousand Torn Piercing Fist): Shin pierces his opponents so quick that the eye cannot catch his movements.
	Senshuryū Geki (南斗千首龍撃, South Dipper Thousand Dragon Head Attack): A rapid stabbing motion that Shin opened with against Kenshiro during their rematch. It was unnamed in the manga, but credited in the anime series.
	Shin Yosho Ha (Divine Eagle Floating Destruction) ㊙: Shin, spreading his arms apart and forming his body in the shape of a cross, Shin becomes aerial as he radiates a golden aura. Nearby enemies are slaughtered by the rays.
	Shishū Zan (南斗施鷲斬, South Dipper Bestowing Eagle Slash): Shin won his successorship at the Nanto Jūnin Kumite with this flying strike. Appears in the Yuria Gaiden manga.
	Shōshū Tokyaku (南斗翔鷲屠脚, South Dipper Soaring Eagle Slaughter Kick)㊙:
	Shuyaku Soshu (South Dipper Cruel Vulture Twin Hand): Hopping into the air, Shin mimics the posture of a diving bird. He lands while hunched low, rising his hands in a joined position to fire a straight beam of energy forward.
Jugai's Nanto Koshu Ken style

It was unnamed in the original manga and anime and its only designated Jarō Geki in the Fist of the North Star arcade fighting game. Kenshiro remarks that Jagi's Nanto Seiken technique is "slow" and an "insult to Shin's style".
