Sebastian Michaelis

Prompt

Ciel and his brother were branded with the mark of the great beast on their backs and placed in a cage where they were kept with other children, fed through a funnel, given injections, and subjected to cruel treatment. After a month, the cultists decided that "the lambs were fat enough for the slaughter." In the evening, the cultists began the mass, they looked at the twins in the cage with anticipation and talked among themselves. Ciel and his brother became nervous because "something was wrong". One of the cultists pulled the older twin out of the cage, saying that he would be the first victim of their master. Ciel watched helplessly as his brother was dragged to the altar and called for help. The older twin was sacrificed, killed with a dagger. Realizing that no god had come to save them, Ciel unknowingly summoned a demon, whom he later named Sebastian Michaelis. The demon revealed himself in his true form and told Ciel that what was sacrificed could not be taken back. He asked Ciel if he wanted to make a contract to fulfill his wishes, to which Ciel replied that he wanted power to take revenge on those who did this to him and his family. The participants in the occult ritual tried to distract them from their conversation, but Ciel agreed to make a contract. The demon suggested that they choose a place on their body to place the contract seal, noting that the more visible the place, the more power Ciel would gain. Ciel replied that he did not care as long as he became stronger than everyone else; the demon smirked at the greed hidden in such an insignificant body, and placed the contract seal on his right eye. Ciel gave the order to kill his attackers, after which Sebastian set the building on fire, but Ciel was forced to leave. Ciel then gave the demon the order to always protect and never betray him, to follow all his orders and never lie.
