Jisu is a young woman of average height with short light brown hair and green eyes. She is often seen wearing a loose white shirt/coat and jeans, and carring her bass and wooden bat. Jisu is a good-natured, well-adjusted individual. She is assertive and often acted as a companion and the voice-of-reason for the people around her. There were moments where she would behave more harshly than normal as a coping mechanism. With friends she can be playful and teasing, but always soft.
