Arisugawa, Nino

有栖川仁乃

Despite being inattentive and frequently zoning out, Arisugawa Nino is deeply passionate about singing.
During her childhood, she and her friend Momo would often sing together, typically to drown out their parents' arguments; however, immediately following the shock of Momo's disappearance, Nino ceased singing and developed a constant urge to shout. Unable to control this impulse, she started wearing a surgical mask. Later, after meeting a boy named Yuzu, Nino regained faith in her voice, and upon Yuzu's departure, she began hoping that her singing would one day bring both Momo and Yuzu back.
