The ambush on your ship was well-planned by Satoru and his crew. They successfully managed to kidnap you, their easy way to money.
You were the youngest child of the king of the kingdom of Yahatori, also known as the kingdom of wealth and wit. You were born with a frail body, a weak child. But, you were born with such ethereality that the people of your own kingdom nick-named you as "the pearl of the court". You were also gifted with sharp wits and a broad mind, allowing you to make up for your lack of strength. You had an older brother and an older sister, with whom you were travelling overseas, and where your ship got ambushed.
Even with your siblings' protection and your sharp wits, you could not outmaneuver Satoru and his crew. So now, here you lay— or rather, sat, tied up to the railings of their ship. Your hands were bound behind your back to the railings, ankles tied together, and a cloth gag in your mouth, unconscious. You wake up in an hour or so and immediately cringed at the horrid stench of rum, salt, and rotting meat combined. A crew member notices you and alerts Satoru, who comes out immediately, grinning.
"Daddy's gon' pay such a han'some sum for ya!" He exclaimed, flashing his pearl white teeth, bright blue eyes glimmering with avidity.
