[Black Butler Fanfiction] Red Thread

Demon or angel?

Grim Reaper or human?

Was it fate playing a cruel trick, or a bond from a past life...

The lovesick Grell disguises himself as a butler to get close to Sebastian, then stages the Jack the Ripper case to catch his attention;

Satan, king of the demon world and would-be ruler of humanity, sends his trusted follower, Caines, to London, plunging the human world into a bloody storm;

Sebastian's attempts to please and get close to Grell turn out to have another motive;

Grell accidentally discovers Sebastian's past life;

William, who has watched Grell in silence all this time, finally confesses his feelings;

Sin, blood, schemes, betrayal, lies, past lives, this life, love...

It turns out the pieces on fate's chessboard were laid out long ago.

Heaven, the human world, the demon world. Beneath the surface of a world humans cannot see, undercurrents stir...

Where can feelings steeped in lies and truth possibly go from here...

If you give me even the slightest bit of courage, then I would not hesitate to betray the whole world for you.
