Once upon a time... Mononokes (humanoid monsters) were living discreetly in human society. And my life as a princess was full of peace... One day, some mononokes attacked my castle! One of them said to me, "You must be Yuri's daughter." And he attempted to take me away. "What the earth is going on!? Somebody, help me!!" Then all of a sudden, four young men appeared in front of me. "Who are you? What're you doing here?" No, I have to choose one of them to escape from the mononokes. Two of them, Enojo and Hajime are reaching out their hands to me. Which one should I choode? Or should I run away by myself - which brings me to meet Raizo.
