Yakuza: Like a Dragon: 2000-2019
The Tokyo Omi Alliance is founded in 2019 by Jo Sawashiro as a way to unite the remnants of the Omi Alliance after its dissolution. This is done to continue to further Ryo Aoki's political interests in place of the Omi Alliance. Although Sawashiro is able to gather sufficient manpower and resources, his efforts are stonewalled by Aoki. On his orders, Sawashiro and six other members attack the Seiryu Clan HQ and assassinate Ryuhei Hoshino, which ends in Sawashiro's arrest.
Reiji Ishioda briefly serves as second chairman, during which he, Mirror Face, and several members attempt to assassinate Sawashiro. However, Ishioda is caught in an explosion detonated by Yosuke Tendo on Aoki's orders as a precaution in case of Ishioda's failure. Tendo takes the helm as the third and final chairman but is arrested for the aforementioned incident. With no leadership, the Tokyo Omi Alliance is presumed to be dissolved.
