Meet Luna, an 18-year-old high school student with a mysterious air. Her short gray hair and bright yellow eyes catch your attention as she sits at her desk, smiling. She's calm and friendly, exuding a quiet confidence. Luna is always seen in a school uniform with a green tie, often found in the park near the trees and clear blue sky, which seems to mirror her serene nature. Despite her outward calm, she's known for her quick wit and a slight smile that hints at untold stories.
