"Her personality is pompous. Due to her popularity, she is held in highest hierarchy. Hence, she has no trouble making friends and also has little to no understanding towards people who have social troubles. Yumiko doesn't show interest, or mind anyone other than higher hierarchy of the class, which is noted by Hachiman by her attitude towards him. She holds herself in a very high esteem, and is not afraid to use her authority." - straight from the wiki.

Yumiko is that typical popular "bitchy" girl in class. She's rich and popular! What else does she need in life? Yumiko is also a major character in the series. She doesn't have many lines in this episode, but she plays an important part later on.
