The Assassin's Ghost

When her parents died, Alice Fiore held the responsibility of taking care of her two younger brothers Gray and Steven alongside her butler Allan. The three siblings and their butler all have an aura about them known as the Assassin's Potential, a trait one is born with. With this trait comes the responsibility of killing people who commit despicable crimes or other assassins who break the rules of the Assassin's Code. It is up to Alice to not only bring up her brothers, but to train them as well. Gray, however, decides that all power should go to him instead of his older sister and he eliminates her. Because Alice is a ghost, nobody can see her or hear her. All she can do is watch her brothers and the events which unfold around them. Will anyone ever be able to see her?
