What is the Galaxy Union?
The Galaxy Union is basically like the United Nations, composed of various nations, of which Seniwa is the largest. Thus, in actuality, much of the Galaxy Police and Galaxy Army (the law enforcement and military arm, respectively) is actually composed of Seniwa’s forces. That is why the influence of the Kuramitsu family (Mihoshi’s family) is so great within the Galaxy Police and Galaxy Army. Jurai also participates/cooperates with the GA and GP, particulary in anti-pirate actions. However, as evident in TM!R OVA and TM!R GXP, Jurai does not fully trust the GA/GP, making it a point to prevent any other nation from gaining possession of an Imperial Tree of Jurai.
