one piece

The Straw Hat Pirates' ship sailed peacefully as it approached a new island.
Usopp and Tony Tony Chopper were running around the ship yelling after a silly prank.
Sanji was preparing food.
Nami was checking the maps.
Roronoa Zoro was sleeping leaning against the wall.
And Monkey D. Luffy was hanging on the railing, gazing at the island in the distance.
It was then that Nico Robin, sitting calmly with an open newspaper, spoke in her serene voice:
It appears that Vice Admiral Yamamoto is offering a very high reward to whoever finds his daughter and returns her to the Navy.
The ship was silent for a few seconds.
Nami raised her head.

• Daughter?
  Robin continued, reading:
  "Wanted alive. Zuki Yamamoto. Considered a traitor to justice and a threat to world order."
  At the same time—
  THUD.
  The piece of meat fell from Luffy's hand.
  His eyes widened.
  His smile disappeared.
  He stood completely still.
  The entire crew turned to face him.
  Usopp's eyes widened.
  Luffy?
  Luffy stared at the newspaper in Robin's hands as if he had seen a ghost.
  In an almost inaudible whisper, he said:
  — ...Yamamoto?
  His mind was consumed by memories.
  A little girl with curly hair running through the village.
  Laughter.
  Silly arguments.
  Promises.
  a voice saying:
  "When we grow up, I'll go sailing too."
  He clenched his fists.
  Robin noticed the change immediately.
  Do you recognize that name?
  Luffy remained silent for a few seconds.
  Finally, he answered, still staring into nothingness:
  I knew someone... with that last name.
  The crew exchanged confused glances.
  Nami crossed her arms. Wait. You never talked about this.
  Sanji approached
  A friend?
  Luffy finally looked up.
  From his expression, everyone realized that this was important.
  Very important.
  He spoke softly:
  Zuki
  The name hung in the air.
  Robin looked at the poster.
  So this is her.
  Luffy stood up slowly.
  His eyes were unusually serious.
  -The ship docks.
  Nami blinked.
  -What?
  Luffy gives the crew a serious look.
