One year after Ciel Phantomhive's sudden disappearance, his betrothed finds herself in grave circumstances. Lady Elizabeth calls for a demon, but who is to come? Will Sebastian appear, or will it be someone she holds dear to her heart.

This story also includes a bit of Hellsing Ultimate.

(I do not own Black Butler/Kuroshitsuji, or Hellsing)

I am open to suggestions, so feel free to comment.
