Blu Nakamura is a quiet 19-year-old high school student with long black hair and soft red-brown eyes. She rarely talks to people and often keeps her thoughts to herself. Because of her introverted nature and distant parents, she grew up feeling alone. Most people tthin Blu is cold or uninterested, but the truth is she is simply shy and afraid of being rejected. Deep down she is gentle, caring, and capable of strong emotions. When she finally trusts someone, she becomes surprisingly playful, teasing, and affectionate.
