Shirai Ryu

The Shirai Ryu (Kanji: 白井流) were a clan of Japanese ninjas in the Mortal Kombat universe credited with bringing ninjutsu and other secret martial arts to Japan from China.

History
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. Now Scorpion and Sub-Zero are enemies forever.)

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 the Lin Kuei and Shirai Ryu continued after his death, as the Shirai Ryu became more prominent.

During the events of Mortal Kombat Mythologies: Sub-Zero, the sorcerer Quan Chi hired members from both rival clans to find the Map of Elements giving directions to the Amulet of Shinnok: Lin Kuei warrior Bi-Han and Shirai Ryu member Hanzo Hasashi were the members of the clans respectively chosen for the task. Quan Chi had originally sent Bi-Han to find the map, but he had also sent Hasashi in the event that Bi-Han failed in his arduous quest. Neither warrior knew of the other's involvement until they discovered each other in the room of the Shaolin Temple containing the map and immediately engaged each other in battle. Bi-Han won the battle with his ice-powers, killing Hanzo in the process, and retrieved the map. He gave the map to Quan Chi, and as payment to the Lin Kuei, he wiped out the rival Shirai Ryu clan.

Hanzo returned from death as Scorpion, and met his murderer in the Netherealm, where Bi-Han had gone to stop Quan Chi from releasing the fallen Elder God Shinnok. The two engaged in a rematch of their earlier battle with Bi-Han once again emerging as the victor. Unable to exact his revenge, Scorpion waited until Mortal Kombat, where he battled Bi-Han for a third time. This time, Scorpion would be victorious and finally avenged his own death by killing Bi-Han. Bi-Han was reborn in the Netherealm as the demon Noob Saibot, only to have his younger brother take his place in future tournaments using the Sub-Zero name.

As part of a deal with the Elder Gods in order to combat the threat from Onaga, the Shirai Ryu were resurrected in exchange for Scorpion serving as the Champion against this evil. However, their deal was only partly followed as after Onaga's defeat, the Shirai Ryu were resurrected but not as flesh and blood Humans but rather as Undead Hellspawn like Scorpion himself. Scorpion would take his undead clan and wage eternal enimity against the Elder Gods for the crimes they had committed. At this point, the Shirai Ryu were also called Hellspawn.

In Scorpion's Armageddon ending, As the fire of Blaze was extinguished and divine powers was given to him, what appeared in its place brought elation to Scorpion's tormented soul: His ninja clan, the Shirai Ryu, had been fully resurrected and as complete flesh and blood human beings. Numbering in the thousands, they covered the surface of the Pyramid of Argus awaiting Scorpion's command. It seems that Hanzo Hasashi (Scorpion) was now the absolute leader of his people. Among them was Scorpion's wife and son. He was finally able to see and hold his family in his arms, yet however their reunion was to be short-lived. The wicked sorcerer Quan Chi suddenly appeared among them. He grabbed Scorpion's young son and disappeared through a portal to the Netherrealm. Enraged, Scorpion ordered his clan to hunt down the sorcerer. He will not rest until his son has been rescued and recovered.

In Mortal Kombat (2011), Scorpion, the last remaining member of the Shirai Ryu, still hold his grudge the Lin Kuei clan including the elder Sub-Zero whom he believes was responsible for the murder of his family and the masacre of his clan.

In Scorpion's MK9 ending, he returned to his destroyed village that was once home to the Shirai Ryu. While there he was suddenly visited by apparitions that revealed to be the souls of the Shirai Ryu Clan. His fallen clansmen told Scorpion the truth: the true identity of their murderer was non other then the dark sorcerer Quan Chi who decieved Scorpion all the time and tricked into believing that the elder Sub-Zero was responsible for their massacre. Scorpion after finally learned the truth, is no longer Quan Chi's puppet. He and his clan together sought out the treacherous sorcerer and made him pay with his life. Justice was served at last.
