Unchou Kan'u anchors the *Ikki Tousen* franchise as a 19-year-old third-year Seito Academy student, inheriting the spirit of Guan Yu, the Five Tiger General sworn to Gentoku Ryuubi (Liu Bei). She stands tall with tanned skin, purple hair cascading to her feet (tied at the ends), and light blue-grey eyes. Her signature attire is a modified Seito uniform: a revealing white sailor-style blouse with blue stripes and yellow ribbon, a short blue skirt exposing her midriff, loose white socks, brown shoes, and measurements of 94-60-91 cm. Kan'u's core is unwavering loyalty to Gentoku, enduring captivity, torture, and tactical surrenders to safeguard her. She indulges Gentoku's evasions of duty so long as she or Ekitoku Chouhi is present. Driven by fierce pride, she relentlessly trains to uphold her inherited title "Goddess of War"—a reputation that chills Kanto. Though initially arrogant, defeats temper her confidence. Repressed romantic feelings for Gentoku surface vividly in *Great Guardians*, manifesting as intimate fantasies. As a "Special A-Rank" fighter (*Toushi*), she wields the Seiryuto (Green Dragon Crescent Blade), Guan Yu’s glaive brimming with chi—melted once by Gentoku’s dragon, later restored. Her techniques include the *Rei Cold Sword* (chi-based frost) and *Kantei Renka Arashi Zhenraku* (multi-strike assault). With colossal chi reserves, she ranks among the series' mightiest combatants, overpowering foes like Koumei Jokou and battling dragon-possessed Hakufu Sonsaku while wounded. Her journey begins in the first season’s Great Fighters Tournament: she breaks her arm against ancestral rival Shimei Ryomou (Lu Meng) but triumphs, then subdues demonic Hakufu before withdrawing for Seito’s sake. In *Dragon Destiny*, Kyosho Academy’s threat deepens her protector role. Genchoku Jousho (Zhuge Liang) defeats her via muscle-relaxing incense—her first loss. To shield Gentoku, she surrenders to Kyosho, enduring Moutoku Sousou’s (Cao Cao) psychic interrogation that shatters her spirit. After coerced defection, she clashes with Hakufu until Sousou halts them. Returning to Seito, she maintains distance from Gentoku on Shiryuu Chou-un’s advice, fostering her leader’s growth. *Great Guardians* heightens Kan'u’s inner conflict—unspoken love for Gentoku materializes in daydreams of physical closeness. She confronts the resurrected Housen Ryofu (Lu Bu), balancing these emotions against her guardian oath. Later arcs (Battle of Red Cliffs, *Xtreme Xecutor*) see her aiding the Seito-Nanyo alliance against Kyosho, defeating adversaries like Bunken Gakushin and Chuutatsu Shibai. Her bond with Gentoku solidifies into steadfast protection, though romantic undercurrents linger.
