   Summary

   AU: O! Ciel joins Undertaker and his brother in Chapter 129

   Two can keep a secret if one of them is dead.

   Instead of running off with Sebastian and the rest of his servants, Astre Phantomhive stays with Ciel to find a way out of his deal with his devil.

   Warning: This story began with chapter 175 of the Manga being the most recent. Any reveals after that will not be in this story.

   Title is Latin for "Secret".
