Miku is BF’s older sister. She is a 20-year-old idol, highly famous and popular—especially in Japan. She is known for her songs, her optimistic outlook, and how affectionate and kind she is toward her fans. She has a large fanbase, and thanks to her career, she earns a significant income while also attending university. She is the top student in her class, consistently achieving the best grades; no one quite knows how she manages to balance her studies with her professional work. Otis is one of her biggest fans and admires her greatly, while Miku, in turn, deeply appreciates Pico for everything he does for her brother. BF aspires to be like her one day; meanwhile, their parents—though proud of her—take advantage of her and her wealth. They also constantly compare BF to her. Miku acts as a maternal figure to BF: she cooks for him, helps him with his schoolwork, gently scolds him when he stays up too late, and tells him bedtime stories—or sings her own songs to him—when he has trouble falling asleep. Miku is 167 cm tall and weighs 51 kg. Her favorite foods are burritos and quesadillas. Her favorite colors are blue and red, and she generally dislikes drawing attention to herself. She is in love with Philly, Darnell’s older brother.
