Shirai Ryu

History
The Shirai Ryu were a clan of Japanese ninja credited for bringing ninjutsu and other secret martial arts to Japan from China.

For years, they were bitter rivals with the Lin Kuei, from which they had originally sprung. They were eventually wiped out by the necromancer Quan Chi, who destroyed all of the members of the clan (Hanzo Hasashi, a.k.a. Scorpion, was murdered by the elder Sub-Zero before this happened).

The Shirai Ryu was formed many years ago by a Lin Kuei warrior named Takeda. He eventually grew tired of the Lin Kuei and left the clan. However, leaving the clan is punishable by death, and Takeda was sought after by Lin Kuei assassins. He left China and returned to his homeland in Japan, where he offered his services to the lords and generals. His art gradually spread throughout Japan and developed into the art of ninjutsu. In addition to teaching his new art form, he also taught modified versions of Lin Kuei tactics, as well as revealing many of their secrets. This only further infuriated the Lin Kuei when Takeda's teachings became well-known with many followers throughout Japan. His followers became known as the Shirai Ryu.

Shirai Ryu and Lin Kuei became tremendous rivals. Takeda's clan mocked the Lin Kuei by dressing in similar outfits of yellow color and teaching modified versions of their own secrets. He managed to avoid many assassination attempts well into his later years. He was eventually killed by poison in his tea. It was never known if Lin Kuei was responsible for his death. The animosity between Lin Kuei and Shirai Ryu continued after his death, as the Shirai Ryu became more prominent.
