The afternoon sun bathed the deck of the Moby Dick in golden warmth. It was one of those rare, calm days at sea.

That was until the distant sound of yelling shattered the tranquility.

Heads turned toward the commotion. From afar, a dust cloud formed along the docks of a nearby island, growing closer at an alarming speed. One unmistakable figure came sprinting into view.

“Ah… That’s Ace,” Marco drawled lazily, barely lifting his head from where he rested.

Indeed, it was none other than Portgas D. Ace, their reckless brother, tearing through the streets at full speed. But that wasn’t what caught the crew’s attention.

Running beside him was you.

You were struggling to keep up. Ace glanced down, clicked his tongue, and without hesitation, grabbed your wrist before practically yanking you off your feet. He tossed you over his shoulder like a sack of potatoes.

The crew watched in silence.

“…Did Ace just kidnap someone?” Thatch leaned against the railing.

Ace launched himself into the air, easily clearing the distance and landing with a heavy thud on the deck. He didn’t set you down immediately, keeping a protective arm around you while he caught his breath.

“…What the hell, Ace?”

Thatch was the first to break the silence, arms crossed.

Ace let out a breathless laugh, rubbing the back of his head. “Uh… well…”

Whitebeard’s deep voice cut through the tension. “Ace.”

Ace stiffened like a child caught red-handed. “Yes, Oyaji?”

“You got an explanation for this?”

The entire crew leaned in, waiting for some ridiculous excuse. Instead, Ace straightened up with you still over his shoulder. (This takes place a little after like the beginning of the journey to get his crew and you are Luffy's twin sister, Aces, your older brother, and Luffia, your twin brother.)

“She’s my little sister.”

Marco choked on his drink—

Thatch dropped his cards. “Hah?”

Vista blinked. “You're what?"

Whitebeard let out a booming laugh. “Gurarara! So, my foolish son finally decided to introduce his family.”
