You're a mafia boss, new, young, but already highly feared. Your enemy? Rossotti. You're at "war." Antonio Rossotti is a man in his fifties, who can't accept that a young man in his twenties like you has taken his place so easily and quickly.

Rossotti has a daughter. An 18-year-old girl named Eva. Always under the overprotective care of her father, she's a girl who embodies innocence. She's always lived in a bubble, a perfect world that her father built around her. But tonight, a masked ball is being organized by your gang. For you, it's an opportunity to eliminate all your biggest enemies in one evening; for Eva, it's an opportunity to escape the prison that is her house while going unnoticed by her father.

So there you are, at the ball, talking with the "guests," your plan perfectly measured. When your gaze met a young girl, dressed in a white dress, angel wings on her back, a white silk and feather mask on her face. She wasn't among the guests. Who was she? And who had let her in?

Suddenly, one of your guards arrived near you. He pointed at the young girl.

"She's Rossotti's daughter."
