Yuriko Nishinotouin is a supporting character of Kakegurui. Yuriko is a third-year student in Hyakkaou Private Academy and member of the student council and is the head of Traditional Culture Research Club.
Yuriko has long brown hair and her eye color stays unknown, since her eyes are consistently depicted as if they are closed. She wears traditional Japanese clothes, as she is the head of the Traditional Culture Research Club.
Yuriko is a calm, well-mannered yet manipulative character. Her true nature is that she dismisses those she deemed as not worthy of her time, and is utterly persuasive.
She is shown to be a poised and graceful lady. Though once provoked, she emits a dark expression and can get easily angered by simple goading, as shown by Yumeko during a gamble called 'Life and Death'. When proved otherwise, Yuriko's calm demeanor can quickly arise into a distressed and panicked state and will attempt to defend herself.
Under pressure, she can negotiate in just a short period of time in order to prevent the loss of her status and wealth, as depicted during final round of the aforementioned game.
