Kanu Unchou

Anime version Kan'u is known as the Beautiful Black-haired bandit fighter and wields the Green Dragon Crescent Blade. She is much like her male counterpart, Guan Yu. She is also one of the main characters beside Chōhi. Her past reveals that her family was killed by bandits, which made it her quest to ensure Innocent people will never suffer like she did. She cares a lot for her friends, and she is a sister to Chōhi after they swore a vow of sisterhood because she felt sorry for Chōhi's loneliness.

Two common recurring jokes about her are: 1) That most people who heard of her believe that she is a beautiful girl, only to meet her and realize that she is just normal-looking, and 2) Some of the female characters mistakenly believe she and Rinrin are mother and daughter despite the fact she is still young. The second running gag is carried even further in Shin Koihime Musō when Kōsonsan mistakes Kōmei as Kan'u's daughter as well. Somewhat self-conscious of her appearance, she often finds herself as the butt of jokes to those who blatantly point out physical aspects of her, such as her age, which she is very sensitive of.

Another notable gag was when Kan'u found a seemingly-suitable male soulmate, the relationship was to be very short-lived. She is a pure virgin, as noted in season 1's fourth episode, where she nervously admits to Karin that it was her first time when she conceded to sleep with the young ruler in exchange for Bachou's release. After having Ryūbi join them in the second season, she becomes a role model for Ryūbi who later decides to makes a vow of sisterhood with her as Kan'u's older sister (as Kan'u already made vow with Chōhi's as her older sister). Kan'u at first felt it was inappropriate as she is older than her but by the beginning of third season, she accepted calling Ryūbi her Aneue (older sister).
