A girl who transfers into Hyakkaou Private Academy. She might look like an attractive young lady, but she is actually a "Kakegurui," someone who finds pleasure in taking risks.

Attractive, smooth as silk, and silver-tongued, Yumeko is a natural-born gambler. Gathering the attention of her peers and the entire student council, there's no denying she enjoys the attention she receives. Despite all odds in a gambling match, she somehow manages to turn the tables in the most daring ways, often times using her perceptiveness to decipher her opponent's tricks.
