OVA
Description
Chiaki Enno is a human female with dark violet hair and dark blue eyes, typically seen wearing priestess attire including a robe and a protective bracelet imbued with holy light. As the 55th-generation descendant of the ancient exorcist Ozunu Enno, she serves as the master of guardian deities Zenki, Goki, Vasara, and Lulupapa. Initially residing alone at Enno Shrine at age 16 (17 by the series' end), she later relocates to Kirin Temple after her ancestral home is damaged.

Raised as a boy until age 15, an unconventional upbringing resulting in a self-reliant and occasionally brash personality, her feminine identity was encouraged when Abbot Jukai gifted her a mini-skirt. She harbors deep-seated emotional needs from her archaeologist parents' perpetual absence during childhood. Trained by her step-granduncle Abbot Jukai, himself a descendant of Ozunu, she honed skills in martial arts, spells, and exorcism. She becomes Kirin Temple's first female disciple, dedicating herself to preserving both the Enno family legacy and the temple's traditions.

Chiaki wields the Bracelet of Protection to summon and transform Zenki from his sealed state into combat-ready forms. Her abilities evolve from initial reliance on spells and charms to acquiring the Yin-Yang Dragon Sword for self-defense in the manga. She masters ancestral techniques passed down through generations, positioning her as a leading exorcist. Her relationship with Zenki begins with mutual distrust following his initial attempt to kill her upon release. She matures from treating him as a servant to viewing him as a younger brother, reconciling after temporarily replacing him with Lulupapa.

Her bond with Abbot Jukai transitions from initial aversion to profound affection. Recognizing his hidden wisdom and loneliness, she increasingly frequents Kirin Temple. A pivotal moment occurs when she kisses him after he saves her life, solidifying their emotional connection. Their relationship, described as a "clandestine affair" in the manga, includes private displays of affection witnessed by temple novices.

In the OVA *Kishin Dōji Zenki Gaiden: Anki Kitan*, Chiaki is 17 and portrayed as notably more composed. Working as a professional exorcist, she investigates disappearances in a village plagued by the demon Kagura. She demonstrates maturity by forgoing typical punitive reactions, such as when Zenki steals her food. She directly transforms Zenki into his "Great Demon God" form without intermediary stages, a feat consistent with the manga. Her mission involves confronting the Ibuki family's sacrificial rituals, allying with two sisters destined as offerings. Despite her efforts, the sisters succumb to Kagura, and Zenki sustains a lasting facial injury during the battle.

Chiaki's personality combines a hot temper with deep loyalty and courage. She exhibits kindness toward family and allies, particularly Jukai, and overcomes fears through her admiration for him. Her growth is marked by increasing emotional resilience as she moves past initial immaturity to prioritize her guardians' well-being. She shares ancestry with the Heian-period exorcist Chihaya Enno, though their direct familial link is unspecified.
