Kumagusu is a minor character in Kakegurui. She is part of Yuriko Nishinotouin's Traditional Culture Research Club. During Life or Death, Kumagusu usually acts as the shuffler who throws the ten swords in the pot and then counts down, while the players bet. Kumagusu is a very strict girl who takes her job seriously. At the same time, she does seem to care a lot about Yuriko Nishinotouin and the club and defends her. When Yuriko is well, Kumagusu is happy too. She is able to keep a good composure, except when Yuriko herself is angry. At that time, she is absolutely terrified. Kumagusa has dark blue hair that is tied up in a bun with a long streak on the left side, empty dark eyes and she two piercings on her right hand that she uses to cheat for Yuriko Nishinotouin during the game. Kumagusa wears the normal school uniform.
Kakegurui: Compulsive Gambler
Unlike many schools, attending Hyakkaou Private Academy prepares students for their time in the real world. Since many of the students are the children of the richest people in the world, the academy has its quirks that separate it from all the others. By day, it is a normal school, educating its pupils in history, languages, and the like. But at night, it turns into a gambling den, educating them in the art of dealing with money and manipulating people. Money is power; those who come out on top in the games stand at the top of the school. Yumeko Jabami, a seemingly naive and beautiful transfer student, is ready to try her hand at Hyakkaou's special curriculum. Unlike the rest, she doesn't play to win, but for the thrill of the gamble, and her borderline insane way of gambling might just bring too many new cards to the table.
