OVA
Description
Kan'u Unchou, real name Aisha, is a central character throughout the Shin Koihime Musō franchise. Bandits killed her family during childhood, including a brother who sacrificed himself for her. This trauma fuels her lifelong mission to protect innocents, driving her vigilantism against bandits.

In the visual novels, she encounters Hongō Kazuto, a modern student transported to ancient China, soon after his arrival. Mistaking his attire and speech for signs he is the "Messenger from Heaven," she rescues him from bandits and becomes the first to swear loyalty. She acts as a driving force for the Shoku faction, performing heroics during the Yellow Turban Rebellion and later conflicts. Initially, she rejects femininity, reacting with hostility to being called a "pretty girl" and showing no embarrassment when seen undressed. Developing feelings for Kazuto, she eventually confesses and loses her virginity to him. She navigates jealousy within his growing harem, accepting non-monogamous relationships, including a lesbian dynamic with Chōryō Bun'en after capture.

The anime adds recurring comedic elements. Legends of her peerless beauty lead to disappointment when others meet her and deem her ordinary-looking. She is frequently mistaken as the mother of younger characters like Rinrin (Chōhi) and Kōmei despite her youth. Age sensitivity becomes a running gag, with characters provoking her by referencing it. Familial bonds are emphasized: she forms a sworn sisterhood with Chouhi Yokutoku (Rinrin) to alleviate Chouhi's loneliness, and later with Ryūbi Gentoku (Tōka). Ryūbi becomes her "older sister" despite Kan'u being older—a dynamic she reluctantly accepts by season three. A key arc involves her offering her virginity to a ruler in exchange for Bachō Mouki's release, showcasing sacrificial loyalty.

Across all media, her personality blends fierce justice, stubbornness, and honor with hidden vulnerabilities. She displays strong leadership and oratory skills, inspiring troops and civilians, but struggles with battlefield adaptability and fear of ghosts. Workaholic tendencies cause stress, and she enforces strict discipline, particularly toward Ryūbi's governance naivete and Kazuto's carelessness. Initially dismissive of femininity, she develops self-consciousness about her emotions and relationships.

Her combat mastery centers on the Green Dragon Crescent Blade (guandao), enabling powerful slashes and precise thrusts. She exhibits exceptional strength (felling trees effortlessly), agility for acrobatics, and skilled horsemanship. Strategic intellect and persuasive speaking enhance her command. Weaknesses include difficulty improvising tactics mid-battle, susceptibility to emotional decisions, and notoriously poor cooking skills.

In the Koihime Enbu fighting game, her gameplay reflects her lore-accurate style, using the guandao for ranged attacks (236X projectiles), anti-air defenses (623X "Dragon Punch"), and overhead strikes (214X). Recommended strategists complement her zoning and close-combat abilities.

Her evolution spans media: visual novels focus on her emotional and romantic growth from stoic warrior to acknowledged lover, while the anime emphasizes familial bonds and comedic insecurities. Shared elements include unwavering protective instincts, trauma-driven motivation, and her core identity as a legendary warrior reimagined through a gender-bent, personal narrative.
