Shin

Shin (シン) is one of the first major antagonists in the series and a boss in Legendary Mode in Hokuto Musou. He is among the Nanto warriors who is born under a star, his star being the "Martyr Star". His star dictates that he will throw away everything that he has for love.

He is Kenshiro's best friend and rival during their training days. However, Shin has always loved Yuria and is disheartened that he could never win her affections. Sweet-talked by Jagi to use evil means for his desires, Shin abandons his respective mannerisms and attacks the couple with a biker gang. He wounds Kenshiro and forces Yuria to say that she loves him. With each moment she hesitates, he stabs his finger through Kenshiro's chest to see how many pokes it will take for his friend to die. By the time she yells a strained confession, he has stabbed into Kenshiro's chest seven times, which creates Kenshiro's trademark north dipper scar.

Determined to make a land for him and Yuria, he creates the tyrannical Southern Cross and calls himself King. Although he says that Yuria had died to Kenshiro, he is actually one of the individuals responsible for her survival.

Fighting Style
In the original release of the comic, his style was just Nanto Seiken and he demonstrated several abilities made prominent in other Nanto styles. As more Nanto users were introduced, Shin's style was renamed to be Nanto Koshūken. His style utilizes his hands and legs to perform various thrusting techniques. He can use enough force from his fingertips and legs to break concrete.
