Destiny seems to guide Liu Bei Unicorn Gundam, as he teams up with Guan Yu Nu Gundam and Zhang Fei God Gundam to deliver a world haunted by never-ending conflicts. Once-thriving nations now lie in ruins, and even though the hope of resurgence shimmers on the horizon, a pernicious invasion of the Yellow Zombie Virus prompts chaos. Those who have been infected assault innocent civilians, and the fortified cities powered by the scarce resource of "Trinity" offer the only safety. However, this has resulted in social disparities and never-ending struggles, with each city ruled by a feudal lord, including the cruel Dong Zhuo. But when the three brave heroes meet, their shared determination to rescue humanity ignites a revolutionary spark. The dawn of a new age unfolds as the trio establishes themselves as the champions of a new chapter in history.
