"Sangokushi [3] Harukanaru Taichi" is an anime adaptation of the historical novel "Romance of the Three Kingdoms" by Luo Guanzhong, set during the turbulent late Eastern Han Dynasty and the subsequent Three Kingdoms period in China. The narrative centers on the power struggles, alliances, and battles among warlords vying for control of the fractured empire. The story begins with the Yellow Turban Rebellion, a peasant uprising that destabilizes the Han Dynasty, leading to widespread chaos and the rise of ambitious leaders.

The main characters include Liu Bei, a virtuous and compassionate leader who seeks to restore peace and justice; Guan Yu, a loyal and formidable warrior; and Zhang Fei, a fierce and hot-tempered fighter. Together, they form a sworn brotherhood, pledging to protect the people and uphold righteousness. Their journey intersects with other key figures such as Cao Cao, a cunning and ruthless strategist who seeks to dominate the land, and Sun Quan, the leader of the southern region of Wu, who balances diplomacy and military strength to secure his domain.

The plot unfolds through a series of political maneuvers, military campaigns, and personal rivalries.
