Isuzu Sohma is one of the supporting of the Fruits Basket series and and cursed by the spirit of the horse of the zodiac. She appears only in the manga and the 2019 anime.
She is voiced by Aki Toyosaki in the Japanese version of the anime, and by Brina Palencia in the English version of the anime.
She is tall and initially has hip-length dark hair; according to an author's note, Natsuki Takaya initially designed her with very short hair but then made it long to mimic the blowing of a Horse's mane in the wind.
When her curse activates, Isuzu transforms into a black horse.
Isuzu is a stubborn and independent girl, to the point she cannot stand being dependent on someone else, traits associated with those born in her zodiac year; she is also sharp-tongued but concerned about others.
When Rin was a child her parents acted affectionate and devoted to her, unlike the parents of many cursed Sohmas, but when she asked if they were happy, the strain of pretending for her benefit shattered the facade, after which they neglected and abused her to the point she was hospitalized and developed panic disorder. After this, her parents kicked her out and Rin moved into Kagura Sohma's home.
Rin and Hatsuharu have a romantic and sexual relationship that began before the start of the series. When Akito finds out about it, Rin claims full responsibility to protect Hatsuharu, and to punish her Akito pushes Rin out a window; while recuperating in the hospital, Rin breaks up with Hatsuharu both to protect him and to avoid burdening him, but without explaining why. To free Hatsuharu, Rin starts searching for a way to break the curse, and asks Kazuma, Shigure, and Ren Sohma for help, though she resists the assistance of Tohru Honda, who she thinks is too nice for her own good.
Ren offers to help if Rin steals a treasure (a black box) from Akito, but Rin is caught by Akito, who confines her in the cat's prison and cuts off her hair; after she is released by Kureno, she reconciles with Hatsuharu, accepting his support. She also accepts Tohru's assistance because of the latter's kindness, and grows as protective of her as of Hatsuharu, getting angry when someone upsets or hurts her.
After the zodiac curse is broken, Rin cannot understand how others can move on as if Akito's abuse never happened, and in the final chapter she says she still gets angry.
