Chūkō Kyocho, inspired by Romance of the Three Kingdoms’ Xu Chu, attends Kyosho Academy as a first-year student aligned with the Kyosho faction. She stands 184 cm tall with measurements of 99-60-91 cm, marking her as one of her series' tallest and most physically endowed female fighters. Born June 20 (Gemini, blood type O), she typically wears gym attire with knee and elbow pads in combat. Her past includes severe bullying at a previous school where male judo members, mistaking her for male, attempted physical assault to verify her gender. Sousou Moutoku intervened, his awakened dragon spirit slaughtering the attackers. Witnessing Sousou's protective rage forged Chūkō's unwavering loyalty, compelling her to dedicate her life to his safety and follow him to Kyosho Academy. This event solidified her general emotional detachment, though she retains deep care for Sousou and Kyosho allies. Classified as a Special A-Rank fighter, Chūkō wields immense strength. During *Dragon Destiny* battles, she overpowered Ekitoku Chouhi by choking her unconscious but fell to Unchou Kan-u's fury at the Battle of Red Cliffs. Chuutatsu Shibai frequently tasked her with monitoring Sousou, utilizing her unique calming influence to stabilize him when his dragon powers threatened consumption. Post-battle, she joined school volleyball, leveraging her height. She also engages with the stitching club, and despite her judo history tied to Sousou, the academy's judo club actively seeks her membership. Her narrative continues in *Xtreme Xecutor*. She confronted Bachou Mouki during Mouki's attempt to reach Sousou and was selected as one of Kyosho's two representatives for the Nanban Island tournament. Surviving an ambush on their transport boat, she swam ashore alongside Mouki, fostering unexpected camaraderie. On the island, Chūkō offered Mouki personal insights into Sousou's character, facilitating peace between them. She later allied with Hakufu Sonsaku during a prison break, repelling Nanban fighters in the culminating conflict. Following resolution, she reunited with Sousou and Kyosho during Teni's recovery. Her stoic demeanor consistently masks profound, protective devotion to Sousou, defining her core motivation.
