OVA
Description
Chie Setouchi is a third-year student at Osafune Girls' Academy who later becomes a first-year student at the National Police Academy. Originally from Gifu prefecture, she moved to Okayama prefecture before her middle school years, which is when she began attending Osafune. Her chosen okatana, the sacred blade she wields as a Toji, is named Sohayanotsurugi.

Chie is characterized by a calm and observant nature, typically assessing situations from a measured distance rather than rushing into action. Despite this reserved demeanor, she has a persistent habit of meddling in the affairs of others, a trait that stems from a deeply ingrained caring nature. This protective instinct is especially pronounced in her relationship with Mihono Asakura, her childhood friend, towards whom she acts as an older sister figure. Her sisterly dynamic with Mihono is further expressed through small but meaningful actions, such as cooking dishes for her and others. When provoked, her normally calm attitude can shift into a more intimidating presence.

Within the story, Chie primarily serves as a supporting figure and a grounding presence for the more impulsive Mihono. Her role as a graduate of Osafune Girls' Academy and a recruit at the police academy places her at a juncture between her past as a student Toji and her future, hinting at a continued commitment to protecting others in a new capacity. Her relationship with Mihono is the most defining of her key relationships, built on a shared history and geographical origin before Chie's family moved, creating a bond that endures despite the physical distance placed between them during their school years.

Chie's development involves the transition from a senior student at Osafune to a cadet at the National Police Academy, representing a natural progression of her protective instincts into a more formalized path. Her personal interests include knitting, and she enjoys crafting small toys in her free time. In terms of abilities, beyond her proficiency with her okatana Sohayanotsurugi, her key strengths lie in her emotional intelligence, her capacity for calm observation, and her domestic skills like cooking, all of which she uses to care for and support those around her. Physically, she is described as having violet hair and blue eyes, with a height of 163 centimeters, and her birthday is February 7th. She also appears in the spin-off series Mini Toji, which depicts characters from the main series in a chibi art style during their school life.
