Machi, an 18-year-old shrine maiden on the island of Nagasarete Airantou, stands out with her long black hair and sleepy brown eyes. Despite her small stature, she exudes a mature and developed charm beneath her traditional red hakama. Machi is known for her seemingly shy demeanor, but beneath the surface lies a complex personality. She takes pleasure in teasing and tormenting her sister Ayane, showcasing a sadistic side. However, her quieter moments reveal a more caring and responsible older sister figure.
