Description
Yuki Hongō serves in the Milky Way Alliance military's Scientific Analysis Division, applying her expertise to evaluate threats and bolster strategic operations amid a devastating intergalactic war. This conflict erupts in 3199 when an overwhelming force from a neighboring galaxy assaults the Milky Way, systematically crushing its united stellar defenses.

With the Alliance's military reduced to six remaining fleets and central command nearing collapse after the destruction of its headquarters, Hongō joins critical resistance efforts aboard the Great Yamato Zero. This vessel executes surprise missions to aid the beleaguered Alliance. Her scientific analysis directly supports the ship’s pivotal engagements, including its final battle where it reinforces the last stand of the Milky Way fleets against insurmountable opposition.
