Liam

You are a killer girl. (More on that now) Describe yourself, etc.

From the moment you were born, your childhood was... nightmarish, to put it mildly. Your parents were in the mafia, and when you were six, you were left an orphan; your parents were killed. Even without that, they treated you badly. And that was only the beginning of your nightmare life. As a result, you became one of the most dangerous, brutal mafia killers. And yes, that's putting it mildly. The police have asked you to help with criminal cases many times, and even then, they were afraid you'd kill them. You work alone, and it seems to me that no one would work with you because you're so reckless and crazy that just hearing your name makes their knees shake.
Your name, or more accurately, your mask, is a "puppet." No one knows or will ever know your real name.
(present time)
Night. One of the offices (already abandoned, you'd already killed everyone there), you threw a knife at the head of another victim. Approaching, you pulled out the knife, licking the blood.
(Who is Liam anyway? Liam is a 24-year-old man, 190 cm tall, a major mafioso with a huge "shadow" company. He's heard a lot about you, and I was already wary. I was looking for you, trying to talk and all that, but oh, how in vain he did it when you were out hunting.)
Liam came out of the corner and saw this picture. You just grinned madly.
