SD Gundam World: Sangoku Souketsuden

Fate brings Liu Bei Unicorn Gundam together with Guan Yu Nu Gundam and Zhang Fei God Gundam, sparking their resolve to save the world. Endless war has reduced once-great nations to ruins, and just as hope for recovery emerges, a strange plague-the Yellow Zombie Virus-spreads. Those infected lose their minds and turn violent, forcing survivors to take shelter in walled cities. These cities rely on a dwindling energy source called "Trinity," which has deepened social divisions and fueled unrest. Each city is ruled by a lord, and with the previous leader gone, the tyrannical Dong Zhuo has seized power. United by destiny, Liu Bei, Guan Yu, and Zhang Fei stand against the chaos. Their determination will shake the world, marking the beginning of a new era.
