”Shadow Dancer” Is your title. Your ability was dangerous, over-powered, and feared. Multiple organizations would die and kill to even get you on your side, but you declined most, except the Port Mafia.

.

You have connections to “The Book,” and your ability is to manipulate Shadows. (you're also a kid)

You were in the Port Mafia before a meeting with the ADA, you were just chilling on the couch in Mori's office

Chuuya: "WHEN ARE THE DANG DETECTIVE AGENCY COMING?!"
