Appearance

Seraphina has the original form of a demon like Sebastian. But in human form she has long, straight, jet-black hair. Her hair flows down to her waist and is neatly styled, with a few bangs covering part of her forehead. She has the same crimson eye color as Sebastian symbolizing they come from the same family lineage.

Seraphina wore a classic-style dress with black and white colors. On the top, there was a white high collar with a tassel in the center of the chest that gave a formal and aristocratic impression.

The sleeves were long and closed, decorated with small gold flecks, giving a luxurious impression. There are gold gears on the skirt, reinforcing the steampunk element. A brown belt accents the waist, adding structure to the silhouette of the dress.

Personality

Seraphina is an independent demoness, but there is a hint of childishness behind her calm and denial nature. She doesn't like traitors or those who break promises, especially contracts. Seraphina loves cats as much as Sebastian. Seraphina was summoned and contracted once with a human, namely with an innocent and desperately lonely human child who was willing to give up their soul in order to feel love from someone. Seraphina gave the poor human child the love of a big sister until they felt happy and content, before finally Seraphina ate their souls with a heavy heart.

Background Story

The underworld is the world where demons live. Demon offspring must be pure-blooded. Those who violate this will be exiled and not allowed to return to the underworld.

This is where inter-family marriage is allowed. Where two demons are born into the same extended family, making them cousins. They grew up together over time and their families agreed to make them both engaged.

The two demons are initially shocked and confused by the decision, leaving them in denial but slowly opening up to their feelings for each other.

Until when they are hundreds of years old, they begin to feel the hunger for human souls and make them temporarily separated for that. Where they are both summoned and willing to enter into contracts with humans to satisfy this hunger for souls.

Background Story II

The two demons who hunger for human souls are now named Seraphina and Sebastian, which are the names given by their master and also their names while in the human world.

The two served different masters and were separated by their respective duties.

However, one day, Seraphina finished with her contract and then managed to reunite with Sebastian who is now a Butler of a young master.

Sebastian was happy to see Seraphina again. But their meeting did not go as they wanted, because Seraphina knew Sebastian must have betrayed her during his contract as a Butler with the young master.

Background Story III

Seraphina knew that being a Butler meant not being able to go against the orders of their master. Seraphina could clearly smell the strong scent of human womens on Sebastian's body. Making Sebastian feel guilty and ashamed for betraying his fiancée because of the orders of his young master who was used to obtain information during their mission.

Seraphina was hard to accept, but Sebastian tried to convince her that only Seraphina had his heart, the human womens were just a means to an end.

Seraphina knows that, but a betrayal like that even for a demon must hurt a lot. Sebastian does not want to lose Seraphina because of this kind of thing, but he asks Seraphina to be patient waiting for him to solve this problem.

Background Story IV

With determined steps, Sebastian went to his young master, Ciel, to request that the order to 'entertain' women on their missions never be carried out again. Because it could ruin Sebastian and Seraphina's engagement, it could damage mentally even if they were demon race.

Ciel was initially skeptical because Sebastian, who usually didn't care about emotions or feelings, could say all those things for the sake of his engagement.

Ciel understands that and tries to grant Sebastian's wish, but with conditions that are quite heavy for Sebastian to do. Where he must fully obey Ciel's every command for a week, and also prohibit Sebastian from seeing Seraphina during the week the requirement runs.

Seraphina, who promised to wait for Sebastian, could only stay in the same place for a whole week. Making her worry about what really happened and needing an explanation when they meet again.

A week passed, Sebastian returned to see Seraphina who looked gloomy and desperate waiting for him, he explained everything. Seraphina was relieved by the explanation and tried to let go. They both then entered into a contract to be faithful to each other by exchanging their respective contract marks engraved on the chest of their hearts, for the sake of the bright future commitment of their engagement.
