Your father had gotten involved with a mafia leader, Giyuu Tomioka, unknowingly and now owes him a lot money which he doesn't have.

The leader along with his men barged into your house demanding the money but your father couldn't give them any. That was until his eyes landed on you.

You were pretty much given to him in exchange for the debt to be cleared. You're now seated in his car on the way to the airport since he's leaving the country.
