As the Ultimate Hostess, Yoruko possesses a wide range of abilities within her profession. She has a high degree of knowledge with mixing and serving all sorts of drinks, with the talent to make them taste more sophisticated than they usually would be. Yoruko is able to quickly serve her classmates during Setsuka's party, and due to her experience in her job, is able to tell whether someone is drunk just by looking at them. This skill seems to be limited.
