Yukino is prideful, talented and extremely smart, but has a tendency to be blunt and point out faults in other people without consideration. She believes that it is the duty of the "exceptional" (a.k.a. herself) to help the less fortunate, which Hachiman Hikigaya refers to as her twisted nobility. In the beginning she has a very cold and unfriendly demeanor, earning her the nickname of Ice Queen, although this changes with her character development as she genuinely becomes kinder and friendlier.
