She is the girl Randou likes, and ironically, she had feelings for him before the accident, though she never shared them with him. Rina has a quiet demeanor and feels responsible for what happened to her real twin sister, Yuna, after Yuna ran away from home. Rina is an emotional person who relies heavily on Randou (as Yuna) for support and guidance.
She is highly intelligent and the smartest student in her class, although she struggles with cooking. Since Randou returned as Yuna, Rina has become increasingly fearful that her sister might leave her again. As a result, she spends more time with Yuna than ever before, seeking reassurance and companionship.
