Black Butler Fanfiction
Yana Toboso's gothic Victorian manga about Ciel Phantomhive, a young earl who contracts the demon Sebastian Michaelis to serve as his butler until his revenge is complete. The fandom has run continuously since the mid-2000s, producing lush period pieces, dark contract-deal explorations, and a great deal of aged-up Sebastian/Ciel content alongside gen casefic about the Phantomhive household. Writers gravitate to the manor's servants, the Undertaker's mysteries, and the question of what happens when the contract finally comes due.
