Yukiko is a rich and elegant young woman who is popular with boys and girls alike. Often scoring the best during exams she is very intelligent. As a smart, beautiful, feminine, respectful and fair-skinned teenager, she has attracted many male characters in Inaba, but acts uncomfortably when someone mentions her beauty. At first, Yukiko is very introverted, but she gets livelier after she is rescued from the Midnight Channel. She also truly appreciates and cares about others and often vows to become an even stronger, more dependable person. Yukiko is also open-minded and straightforward. Yukiko is not only shown to be quite fearless and unflinching in the face of creepy atmospheres and surroundings. Her biggest insecurity is being chained down. Her whole life she has felt she is on a railroad track with no opportunity for deviation. She then develops a desire to run away from such life and start anew.
