They might start off as friends but gradually realize their feelings for each other in a 'Black Butler Love Story'.
Maybe Grell and Sebastian. Grell has a very strong fascination with Sebastian in the original series. In a love - themed version, this could develop into a more serious relationship, with Grell's over - the - top personality creating some interesting dynamics in the love story.
It could be Sebastian and Ciel. Their relationship in the original is very deep and complex. In a love story, the loyalty and protectiveness that Sebastian shows towards Ciel could easily be transformed into romantic love.
One possibility could be Sebastian Michaelis, the demon butler, as the snake in a transformed state falling in love with Ciel Phantomhive. It would be a very strange and complex relationship as Sebastian's loyalty is supposed to be to Ciel in a more master - servant way, but if he were a snake in love, it would completely change the dynamic.
A love story with Pluto could center around his transformation. He was once a normal dog before becoming a demon. If he were to fall in love, it could be with someone who saw him both as the innocent dog and the powerful demon he became. This love could be a catalyst for him to question his place in the world of Black Butler, whether he should continue to serve his master blindly or follow his heart in the matters of love.
The main characters are Ciel Phantomhive and Sebastian Michaelis. Ciel is the young earl seeking revenge, and Sebastian is the demon butler who serves him.
In a Black Butler Sebastian love story fanfiction, a good match for Sebastian could be a librarian. She is well - read and can engage Sebastian in intellectual conversations. She also has access to a lot of knowledge about the occult and other things that might interest him. Another possibility is a young journalist who is always seeking the truth. Sebastian would find her tenacity and curiosity appealing. Or perhaps a female bounty hunter. She has a tough exterior but a kind heart, and her skills in tracking and fighting would be something Sebastian could respect.
It could be a new female character with black hair and red eyes. She could be a witch who has a connection to Sebastian's past. Maybe she was once his ally but now has her own agenda in the 'Black Butler' world.

Ciel and Sebastian are central, but other important characters from the side story include the servants in the Phantomhive manor. There's Bardroy, the cook with a past in the military. Finny, the gardener with superhuman strength. Mey - Rin, the clumsy yet endearing maid, and Tanaka, the wise old butler. They all add to the charm and complexity of the Black Butler Side Story.
The main characters are Ciel Phantomhive and Sebastian Michaelis. Ciel is the young earl seeking revenge. Sebastian is the demon butler who serves Ciel while waiting to claim his soul.

Also, in the world of Black Butler, there are always dangerous enemies around. His love might be put at risk because of his association with the Phantomhive family, as their enemies could target those close to the servants.
