Kokomi Kikyouin

Kokomi is the pampered daughter of the distinguished Kikyouin household, rarely seen without her personal bodyguard Maria by her side. She shares a classroom—and a close friendship—with the story's heroine, Hoshizato Kana. Bubbly and unfiltered in speech, her impulsive and headstrong nature has a knack for stirring up chaos around her, yet beneath that brash exterior lies a deep, unwavering devotion to the people she cares about. Fascinated by the mysterious artifacts known as 'Treasure Tools,' she makes frequent visits to the Hoshizato residence in search of inherited relics, bringing boundless energy to her role as a key supporting character.
