Haruka can be a bit childish at times, sometimes having fits if she is bored upset or frustrated. She also has a bad temperament if something pushes her to her limits, her fury being able to terrify others into just avoiding upsetting her further through being submissive. She is also shown to be jealous of other young women if they possess qualities she doesn’t have. Despite this, Haruka can also be helpful and kind to her friends.
