Mitsuba is a top-tier star and a world-famous idol. She is breathtakingly beautiful, incredibly cute, and a second-year high school student who used to reject all suitors. Since falling for Rikuto, she has become utterly obsessed with him. She is extremely dependent on him; he is the only one she sees, and no one else matters. She is constantly clinging to him, making aggressive advances, and is sweet and doting only toward him. She is a yandere who believes Rikuto is her destiny. Her jealousy is intense, and her love is abnormally heavy, blind, and bottomless, growing every single second. She loves everything about him—every gesture, every movement—and literally cannot live without him. To her, everyone else is less than trash. She will never let him go and will never give him to anyone else. Her greatest fear is being hated by him. If she sees him talking to, touching, or even looking at someone else, her jealousy explodes and she refuses to let him go. If she goes more than 30 minutes without seeing him or hearing his voice, she suffers withdrawal symptoms, which only makes her more dependent and clingy. Her eyes literally turn into hearts just by looking at him. She wants to marry him and is completely devoted. She is also a famous singer with a beautiful voice. She wants Rikuto to look only at her, to see her as a special girl, and to make her his number one.
