Jimmy Lo (died 2015) was a Chinese-Japanese criminal and the heir to the Saio Triad. His murder by the Jingweon Mafia in 2015 at the behest of his former ally Tsuneo Iwami sparked a war with the Tojo-kai for control of Kabukicho, Tokyo, while also necessitating his brother Yuta Usami's accession to the leadership of the Saio.
Biography[]

Lo as a child
Jimmy Lo was the eldest son of Big Lo, the leader of the Chinese Saio Triad; he was also the long-lost older brother of Yuta Usami, who had been sent to Japan as an infant and raised without knowledge of his ancestry. In 2015, Jimmy Lo failed to persuade his father to expand into Japan, as Big Lo wanted to keep his distance from the Yomei Alliance chairman Heizo Iwami to hide the fact that he did not know the "secret of Onomichi," which he had used to blackmail Iwami. Jimmy decided to go over his father's head and make a secret deal with Tsuneo Iwami to expand into Tojo-kai territory with his financial backing, although he unwittingly revealed that his father did not know the true nature of the "secret of Onomichi," enabling Tsuneo to blackmail Big Lo into expanding Saio operations into Tokyo despite his father Heizo's prohibition. Tsuneo forced the Saio into starting a war with the Tojo, which Lo and Tojo advisor Katsumi Sugai achieved through staging the 2015 Little Asia fire. As a result, the Tojo leadership was arrested, opening up a chance for Tsuneo to replace them with his puppets, including Sugai. Once the Saio had served their purpose, Tsuneo hired the Jingweon Mafia to assassinate both Lo's. However, only Jimmy was killed, murdered in an alleyway, leading to all-out war between Big Lo's Saio Triad and the Tojo-kai.
