Going unnoticed by no one at St. Francesca Academy, Fuyurugi is the sempai everyone looks up to. She uses an archaic style of speech, and carries herself in a cool and gracious way.
Due to her strict personality, she can sometimes be too serious about things, but she sometimes has trouble handling her finances. The head of the kendo club, she’s pretty much at a genius level when it comes to kendo and hasn’t lost a single match for several years.
She is a character from Harukoi Otome ~Otome no Sono de Gokigen'you~(春恋＊乙女 ～乙女の園でごきげんよう。～), as one of the heroines that the protagonist, Hayasaka Akihito, can pursue. Due to St. Francesca Academy being present in both VNs, her name is mentioned in Koihime†Musou as one of Oikawa's ex-girlfriends and Kazuto's upperclassman. She is the head of St. Francesca Academy Kendo Club which Kazuto is a member of.
In Harukoi Otome, it is mentioned that she hasn't lost a match in several years; Kazuto reflects this in the beginning of Koihime†Musou, saying that his current goal is to defeat her.
