Yumemi Yumemite is a supporting character in Kakegurui. She is a part-time idol as well as the Student Council's Head of Public Relations.
Yumemi is a girl with an average height. She has very light skin and long light brown/slightly pink hair, which part of them is styled into two ponytails that are tied with white hairbands (or what looks like scrunchies). Her eyes are blue with white pupils which are in the shape of star. She wears the Hyakkaou Private Academy issued uniform; a red blazer with black trim lining the cuffs and collar with purple flower in the middle, a white button up dress shirt, a dark pleated skirt, a tie and white colored stockings. As well as the academy's issued footwear, brown colored loafers with black soles. She also sports light pink lipstick and has pink painted fingernails. During her performances, she manages to create a much cuter image for herself with shorts skirts and pink colours.
Yumemi has a two-faced personality. On the outside, she's a sweet, lovely girl who loves her fans above all. However, in reality, she's an arrogant, calculated and sadistic person, who will do everything to be on top. She's also disgusted by her fans, often calling them 'pigs' but at the same time, she doesn't want to turn in meetings with them, due to her dream of becoming a famous actress in Hollywood.
Yumeni never enjoys the dancing routines the fan club comes up with and has shown to be disguted by their 'sweaty gross palms'. She is motivated by stating on top and achieving an academy reward which is why she involves herself with the fans as much as she can. Even though she is mostly foucsed on herself, she manages to remember the birthday dates of all her fans in her fan club which she tries using to her advantage when she gets herself caught in a gamble with Yumeko.
