Mouki Bachou carries the spirit of the ancient warrior Ma Chao within her magatama, serving as his modern successor and sole heir to the Mouki clan legacy. After initially attending Ryoshu Academy, she transfers to Seito Academy, becoming one of Gentoku Ryuubi's "Five Tiger Generals" alongside Kan'u Unchou and Kouchuu Kanshou. She possesses auburn hair, golden or amber eyes, and a buxom figure with measurements of 82/55/83. Her typical attire includes a pink coat worn over her school uniform, pink fingerless gloves, and sneakers; she occasionally wears her hair in a ponytail, leading to comparisons with Hakufu Sonsaku in the manga. Her personality varies between adaptations: the anime portrays her as impulsive and ditzy like Hakufu, often acting without thought during fights, while the manga depicts her as more aligned with Gentoku Ryuubi – absentminded yet deeply compassionate towards comrades. Both versions emphasize her fierce loyalty and occasional naivete. A pivotal aspect of her character involves the spirit of Ma Chao awakening within her when friends or allies face grave danger. This spirit temporarily seizes control, unleashing violent, overwhelming combat prowess distinct from Hakufu's draconic state, representing a full spiritual takeover. Mouki typically reverts to her usual self afterward with no memory of the event, illustrating the risk of a Toushi being dominated by their magatama's ancestral will. Her narrative arc in *Xtreme Xecutor* sees her infiltrate Kyosho Academy to confront Sousou after her brother Kansui suffers near-fatal injuries. She defeats multiple adversaries, including Soujin, before being stopped by Kyocho. Later, found despondent in the rain, she encounters Ryuubi, who affectionately dubs her "Maa-chan" and invites her into Seito. Mouki harbors a notable fear of snakes, evident during a mission with Hakufu at Nanban, though she briefly overcomes this phobia to help behead one. She repeatedly battles the Kentei-infused Teni across various locations. Her relationship with Koukin evolves from her dismissively calling him "a goldfish shit" and feigning dislike to acknowledging his worth, revealing a semi-mild crush. Following Kentei's disappearance and Hakufu's apparent demise, she heeds Sousou's counsel and formally joins Seito. Her development includes training sessions with Hakufu, whom she views as a mentor, and gradual integration into Seito's ranks under Ryuubi's guidance. The coexistence with Ma Chao's spirit remains a defining aspect, reflecting the series theme of ancestral fates shaping contemporary lives.
