Chiori

Chiori is a famous fashion designer from Inazuma who is currently running Chioriya Boutique in Fontaine and is one of the Komaniya Express's regular customers. She left Inazuma when the Vision Hunt Decree and Sakoku Decree was enacted and has not returned since. Chiori usually speaks in a blunt, straightforward manner, which can take some time to get used to. Her methods of resolving disputes can be considered radical, as she does not like wasting her time on explanations. She is also particularly prideful with her clothes[2] and even scolding Lyney on one occasion when his outfit got damaged.[3] However, if the situation calls for it, she does not mind having them damaged and/or destroyed.

In her youth, Chiori was often a troublemaker and considers herself spoiled by her parents. In one instance, she even snuck into the Kamisato Estate.[4][5] She developed an interest in needlework and shows immense skill, thus resulting in her parents sending her to a master tailor to refine her craft. However, she soon came to learn and despise arrogant higher-ups, thus resulting in incidents that made her leave Inazuma for Fontaine. Her Geo Vision showcases her determination to follow her own path without succumbing to outside influences.

After an encounter while delivering a package to her, Chiori made Kirara's current outfit, Whirling Bloom, after being displeased with her appearance at the time, which she described as akin to being "unceremoniously dropped in a bucket of paint". This resulted in her store becoming more known as people inquired about the outfit.[2][6][7] She also tailored the outfits worn by Lyney, Lynette, and Navia, as well as the accessories for Charlotte's Kamera, Monsieur Verite. Chiori is very popular among the people of Fontaine, ranging from the upper classes to even muscle men who treat her with respect and gifts; anyone who disrespects her are promptly thrown out of her store.[8] While people are willing to pay for her clothes, Chiori is not particularly driven by wealth, rather being more interested in increasing the reputation of her name and store.[9]

Chiori is good friends with Chevreuse, though her hard-handed methods to solving problems often leaves Chevreuse exasperated. She is also good friends with Navia, as the two young women share similarities with each other. It is also implied that she does not like competition in the fashion industry, as she quickly drives out malignant competitors[10] and had nearly done the same when she was learning the trade in Inazuma.
