Together with me, we shall go to a new world. "Yes, senpai, I have decided to make you mine." A technological cutting-edge city, Shinsui. Everything about life there is exciting, with new discoveries and inventions popping out every day. In that city, lives a genius girl, Tsukigaoka Ran. Her clear-headness might be something we call genius, but nobody understands her. Even Tsukigaoka Ran herself, does not understand what kind of being she is. No, she should've known. What is she. But, she doesn't really know. The feelings of love and the like that begins to sprout within her. Tsukugaoka Ran's feelings of love. Another new thing born here in Shinsui. It may be the single most exciting thing to witness with your own eyes.
