Rika Orimoto is the childhood friend of Yuta Okkotsu. One day while walking home, Rika Orimoto is tragically killed in a traffic accident. Yuta witnesses this and becomes cursed by her spirit. It isn't until later that we find out that it was actually Yuta who cursed her and wasn't ready to let go of her. Rika always seemed cheerful and happy to be with Yuta. When Yuta was able to lift the curse, Rike forgave him and even said that she was glad to be cursed with him.
