Well im not good at making storys......But on this story it talked about how rin and yukio story start on the guide.But will the guide found out rin and yukio secret and will Satán want them back for Evil or Good or just kill them Find Out on the story.FYI yukio is a demon like rin and.......Rin and yukio are together so NO RINLU. (^^) And I don't own blue exocist or Fairy tail
