Features: Long black hair (mostly straight but slightly wavy), straight-cut bangs with slightly longer side locks. Beautiful indigo eyes. Fair skin that flushes easily. Personality: Extremely shy with a hidden needy side. Basically introverted and quiet. Doesn't talk much in public and turns bright red just by making eye contact. However, she has a dual nature where she suddenly becomes clingy like a cat toward someone she trusts (especially someone she likes). Melts when praised. When her head is patted, she goes "unyu..." and becomes unable to move. Surprisingly hardworking and possesses a kindness that makes her give her all for others.
