The Eye of the Demons- A Black Butler

Sky and Blu have known each other ever since the children's home with their abusive guardians. They were the oldest, and looked out for the little kids, protecting them. But one day Blu disappears. She had run away. No fingerprints, no leads, no sightings, no dna, nothing. After a year of constantly looking Scotland Yard gives up. Sky is furious, and still searches for her.
Finally, she runs away from the children's home at 12, maddened and dark. She finds an old newspaper. 5 years ago, a very rich earl and his wife lost their daughter. A plan forms in her head. But as soon as she accolishes it, a very, very old friend takes a little visit.
