SD Gundam World: Sangoku Souketsuden

After meeting Guan Yu Nu Gundam and Zhang Fei God Gundam, Liu Bei Unicorn Gundam decides to defend the world as though guided by fate. Wars have repeatedly destroyed once-prosperous nations, leaving the land in ruins. When recovery seems imminent, an outbreak of the enigmatic Yellow Zombie Virus occurs. The virus carriers become disoriented and begin to assault humans. The survivors are compelled to live in walled cities, relying on a type of energy known as "Trinity," for protection. However, social stratification and considerable conflict have resulted from this finite energy. Walls separate each fortified city from its neighbors, and lords rule over each nation. Since the death of the former lord, the lord Dong Zhuo has been acting outrageously. Liu Bei Unicorn Gundam meets Guan Yu Nu Gundam and Zhang Fei God Gundam as though brought together by fate and decides to save the planet. The three young men's devotion will ultimately lead to a significant transformation of the planet. A fresh section of history is revealed by the new heroes!
