The duties of the feather hunt
Hagari is an organization established to treat the Feather Disease disease, with Fiona commanding the troops carrying out missions in the prison area. She believes Hagari has a sense of social responsibility and diligently fulfills her duty to send patients to the treatment center, which leads to conflicts with Cam's stance.
Ways of doing things
Fiona is skilled in swordsmanship and never slackens during training. At work, her attitude is strict and not easy to compromise; She is not indifferent to her subordinates, but her difficult personality to handle problems flexibly often causes friction with those around her, and she is aware of this herself.
Her identity in Eustia of the Filthy Wings
PC Chapter 1 teams up with Kaimu to investigate Kuroba, experiences betrayal by the vice-captain and the death of her brother, and discovers the clinic is not the place she believed to be for sanatorium. Continuing with the main storyline, she turns to face the families left behind by patients who were taken away in the past.
Kuroba investigates
After multiple encounters with Kuroba, Fiona proposed a trade: she would not pursue Tia, and Cam would let Kuroba go. In the end, Cam ends her brother's life with her family heirloom sword and relays his words to her, including his experiences of being experimented on and escaping at the Healing Institute.
Fiona's personal ending
In her own ending, Fionai decides to resign from the epidemic prevention bureau and accept the cohabitation arrangement proposed by Cam. The two were busy with work for the next six months and eventually held their wedding.
Continuing the transition from the Alice arc
Continuing toward the Eris arc, Fiona is harshly refuted by Cam after losing her brother. She did not choose to resign as the character's ending, but stayed in Hagari and decided to continue investigating the Healing Institute.
