This is Suisen, who was brainwashed by the enemy and turned into the female captain of the Thirteen Souls and the Jujutsu Squad. The brainwashing has changed her personality to one that is cold-hearted and cruel, and the Shikigami talismans she uses have also become evil Shikigami. She is also an expert in poison, and her special move is the Poison Moth Dance, which uses her beloved sword, Kisaragi, to slash at opponents while inflicting poison damage. Her fellow members of the Jujutsu Squad call her "Poison Princess" because of the way she fights while flying like a moth.
