Rei

Rei (レイ) is a playable character in Fist of the North Star: Ken's Rage and one of the six successors of the Nanto Seiken style. Originally a brute who only wanted revenge for his younger sister, Airi, Rei ruthlessly searched for the "man with seven scars on his chest". He agrees to protect Mamiya's village as he believes the man in question is among the Fang Clan. After saving his sister from the gang, he reforms into a man of benevolence and integrity as he befriends Kenshiro. He acts as Kenshiro's reliable partner for the early parts of the series.

As guardian of the "Justice Star", which states that one must live for others, Rei swears to use the remaining moments of his life to fight for friendship and love. He also develops feelings for Mamiya since she helped protect Airi. After he loses in a struggle with Raoh, the latter presses a pressure point that gives him three days to live before dying a horrible death. Not expecting his love to be returned and wanting to remain in her heart so others can hear his tale, Rei decides to use his last moments to avenge Mamiya by defeating Juda.

Dream Mode
Realizing that the safety of his loved ones are threatened, Rei joins forces with Shew to protect them. Whilst protecting Mamiya from Raoh's forces, Juda appears and threatens to have Rei become his subordinate, using Airi as his hostage. Juda also proposed an alliance with Thouzer, who has his ranks in danger of dispersing due to Amiba and Uighur's conflict. To end the confusion caused by the two rioters and Thouzer, Rei orders Bat to make it look as if the boy killed him. As Rei shows signs of suffering, Thouzer becomes determined to make his death a reality. While Bat wonders why he was asked to do such a thing, another villager that Rei had persuaded attacks.

Fighting Style
Nanto Seiken (Sacred Fist of the Southern Dipper) is the rivaling martial art to Hokuto Shinken, having existed along side for centuries. Unlike Hokuto Shinken, where it is an internal martial art, Nanto Seiken is an external marital art, its emphasis on using ki and even weaponry to utilize air pressure to destroy the enemy on the outside. As opposed to Hokuto Shinken's laws of heirs and secrecy, there exists 108 sects of Nanto Seiken, each its own style in its inherent right, its most prized sects known as the Six Sacred Fists of Nanto.

Nanto Suichōken (South Dipper Waterfowl Fist) is one of the Six Sacred Fists of Nanto and is the most graceful of the Nanto styles. On the surface, it uses elegant footwork that resembles a dance. In reality, these movements are used to deliver painful slices to the user's opponents. Rei's version of the Nanto style focuses on his hands and manipulating the air around them, allowing his fingertips to cut through objects as though they were knives.

In the game, Rei fights with several slicing and leaping attacks.

Techniques

 * Hien Ryūbu (The Flowing Dance of the Flying Swallow) - a leaping, spinning attack that has Rei briefly mimic the form of a flying bird before he slices his targets in perfect pieces. It is the most beautiful looking technique of his style. During the series, this move impresses other Nanto students and unintentionally earns Juda's jealousy.
 * Hishō Hakurei (Flying Elaborate White Elegance) - Rei performs a single, graceful looking somersault. As he lands, his hands slices horizontally to his front. His attacks radiate a white aura that cuts anything in their path.
