Unchou Kan'u, successor to Guan Yu and bearer of the "Goddess of War" mantle, serves as the fiercely loyal protector of Seito Academy’s leader, Gentoku Ryuubi. Her imposing stature, tan skin, and athletic frame command attention, accentuated by floor-length dark purple hair and piercing blue-grey eyes. She wears a revealing Seito uniform, later switching to a somber Kyosho-aligned outfit during a tense alliance, reflecting shifting loyalties. Her life centers on shielding Gentoku, a duty tested during the Great Fighters Tournament, where she battles through injuries—even a shattered arm—to defeat adversaries like Ryomou and Hakufu Sonsaku. Choosing Seito’s survival over victory, she withdraws, later aligning temporarily with Kyosho’s Sousou to safeguard Gentoku. This choice leads to imprisonment and interrogation, though her restrained power hints at dormant, unyielding strength. Overconfidence gives way to vulnerability as she clashes with Koumei Shokatsuryou, initially dismissing then reluctantly respecting his capability to guard Gentoku. Buried romantic feelings for Gentoku surface in confessions to Koukin, exposing tension between devotion and hidden longing. To foster Gentoku’s independence, she briefly steps back, only to reemerge in crises like the Battle of Red Cliffs, ensuring her leader’s survival. Armed with the Blue Dragon Crescent Blade, Kusanagi, and chi mastery, she defies prophecies foretelling her death by Ryomou’s hand—echoes of their Three Kingdoms predecessors. Repeatedly surviving lethal confrontations, she balances physical endurance with emotional resilience. Later arcs delve into sacrificial loyalty, enduring captivity and manipulation for Gentoku’s sake. Daydreams of intimacy with Gentoku in the third season underscore unresolved romantic yearning. Her eventual truce with Koumei and mediation of Seito-Nanyo alliances mark her transition from lone warrior to diplomatic strategist, cementing her legacy as both shield and unspoken catalyst for unity.
