Then on his way home from school Hiromu finally meets a boy who remembers Tetsuya and says that Tetsuya was "delicious" and this isn't the only strange occurrence. This boy seems to think that Hiromu's name is Glorious Lily and that his lover is not his girlfriend, but a beautiful, emotionless girl named Valeriana. With the help of this mysterious boy Hiromu uncovers his past, who Valeriana is and who, or what, he is.
