A somewhat shallow girl who doesn't think about the future and prefers to live in the moment. She is extremely blunt about her feelings, especially when something displeases her. Yuka is indifferent to other people's suffering, but will lash out and complain childishly when something affects her. She is a bad student, but despite her bad grades, Yuka has a natural ability for observation. She also makes use of kokalgo (kogal slang), which was translated to valley girl slang in the American version of the game.
