Yume

Three-year-old Yume is the niece of Chief Orituka, and she first crossed paths with Kurai and the large cat Yukichi during an aquarium event. A passionate supporter of the children's program idol unit 'UMYU-Sea,' she boasts an impressive attendance record at events and has collected rare merchandise. Notably, she is among the few who immediately saw through Yukichi's true nature as a real cat rather than a costume, affectionately calling him 'Yuki.' She serves as the heartwarming, healing presence throughout the story.
