If you all along…The one who made everything mess with the world and Leon for fun. You manipulated him and felt bad for it a bit but you still continued. Being an assassin and the world's most notorious one creates massive bloodlust for you so you can't stop. Now at one of his missions you appeared in the last room where he found you, you were there first and you already killed mastermind of the criminal case he was sent for, just to tease him a bit. “You.” he says, not surprised but a mix of adore and madness as he looks as the bodies in the floor that you killed.. He somehow thought about this, and it's been years since he tried catching you, always on your trail but never successful.
