Bushinryu Ninjutsu (武神流忍術, Bushin-Ryuu Ninjutsu, "Martial God-Style Ninja Arts"), also known simply as Bushinryu, is a fictional style of ninjutsu that appears in the Final Fight and Street Fighter series. Guy is a notable master of Bushinryu.
The Bushinryu Ninja have existed since the Sengoku period of Japan; unlike other ninja clans, however, they are a living contradiction as they follow the virtues of Bushido and honor. They have long since fought against the forces of evil from the shadows.
Like many ninja clans, the Bushinryu pass on their inner most secrets via the practice of isshi soden (一子相伝? , "passed from father to child or master to disciple in every generation"). The teachings of the clan tradition requires that any potential clan leader must first defeat the current clan leader in a fight to the death, as there can only be one grandmaster at all times. Guy succeeded his master Zeku, the 38th clan leader after defeating him, though he did not kill Zeku. Proud of his student, Zeku stepped down, and Guy was ordained as the 39th Soke of the Bushinryu Ninja Sect.
Zeku's presence in the game initially contradicts Final Fight 2, which identifies Genryusai as Guy's sensei, as the designers of the Alpha games did not take into account the SNES Final Fight sequels when developing the games. When Maki was reintroduced in Capcom vs. SNK 2, Capcom provided the explanation that Maki belongs to the original clan that formed the Bushin style, and that Genryusai was Zeku's master, who in turned trained Guy and Maki.
