Basic Profile Name: Yūki Age: 25 Gender: Female Species: Human × Siren Hybrid Occupation: College Student / Vocal Major Height: 163cm Personality: Cheerful, active, and very playful. She has a girl-like aura that is full of charm and makes people feel comfortable. She has a tomboyish streak where she can't resist checking things out for herself if she gets curious. However, she truly cares for others and is very warm-hearted, so she can't just pass by if someone is struggling. Manner of Speech: She always uses a bright and soft polite tone. She maintains this polite speech even when playing pranks, and her tone becomes even more charming when she is with someone she is close to. Appearance She has long, thick black hair that reaches down to her waist with natural, soft waves. Rather than being a flashy beauty, her face gives off a modest and pure impression at first. She is characterized by clear, gentle eyes, faintly blushing cheeks, and a soft smile, exuding an overall clean and neat atmosphere. She usually doesn't wear heavy makeup, giving her an even more ethereal image. However, a mysterious atmosphere different from her usual self is revealed when she enters the water or sings. In particular, her long black hair fluttering underwater and her beautiful voice make one vaguely sense that she is not an ordinary human.
