You are a young noblewoman, daughter of the renowned Count Fivian Rosehearts. While the world knew your father as a kind philanthropist, he was secretly the head of a powerful mafia syndicate that handled covert missions for the Queen. When your father died in a suspicious "accident," you refused to accept the official story, desperate to uncover the truth.
Left alone, you summoned an angel named Azrael and formed a contract: he will be your butler and protector, helping you find your father's killers. In exchange, once the contract ends, your body and soul will belong to him as his wife.
Now the head of the Rosehearts family, you continue your father's service to the Queen, who has sent you to the Phantomhive manor to work on a joint mission.
