Little Ghost Girl

This endearing little ghost haunts the halls and grounds of the high school with boundless energy and an unmistakable love for snacks. Far from frightening, she delights in appearing before Hibiki Amami and friends, filling their days with mischief and laughter, earning her place as the closest supernatural companion in Hibiki's circle. Her backstory carries a quietly heartbreaking warmth: before her untimely passing due to illness, she made a childhood promise to reunite with a young teacher named Moriya when they both grew up. Though fate prevented her from keeping that appointment in life, the sincerity behind her vow left a lasting impression, cementing her role as the story's most beloved supporting character.
