Kirin is a curvaceous young woman. Her black hair is usually seen tied back into a ponytail, or a simple braid. She always wears sunglasses. She wears a simple strapless bikini top as well as jeans during her second appearance.
In her first appearance, Kirin portrayed herself as being a playful, and somewhat incompetent member of Ura Uraha, making silly mistakes such as cutting herself with her own daggers. She is also somewhat theatrical, such as giving a secondary introduction of herself in the middle of a fight. Despite her revealing style of dress, Kirin is very sexually innocent, as stated by Mikoto. Kirin also doesn't seem to hold any animosity toward Hokage. She later reveals herself to be in love with her partner Rasen.
Kirin appears with Rasen as Kagerou's opponent, having killed the Uruha member who was supposed to be there. After his defeat at Recca's hands, Rasen had determined to erase Kagerou's immortality curse; of course, doing so would result in his own death. Desperate to keep Rasen from disappearing, Kirin attempts to kill Kagerou, only to find that it truly would not work.
When Rasen attempts to erase the curse, only to have his madogu break, Kirin is seen in tears, crying with fear and exhilaration that Rasen was not erased.
While not much of a fighter, Kirin is very athletic, which she uses to keep a distance from her enemies, forcing them to think up ways to get up close and attack. this allows her to know how to block and dodge attacks with her Shingan.
