Excuse me I'd like to ask if you could please write a One Piece story. Marco the Phoenix by T/n T/n is Ace's younger twin sister. Unlike her brothers, she enlisted in the Navy.
She was Akainu's student, but he didn't know who she was, or that pirate blood ran in her blood.
Y/n reached the rank of vice admiral of the navy. After a while, Y/n would occasionally give information about ships with certain merchandise to the white-bearded pirates since her brother had joined them. One day, when she was supposed to exchange information, she met Marco the Phoenix. She always heard great deeds from that pirate. 4 months later Y/n apologized. I'm sorry. This will be the last time I can give you information about the ships or merchandise. Ace looked at her, "Uh, why?" Y/n smiled. "I'll be assigned to Marijoise." Both men stared at each other.
Days later When Narba Blanca found out, he was furious. He had tolerated the daughter of his friend and former pirate rival becoming a marine simply because she met Ace and Marco, and they knew she was safe. But if she went to that place, No, he shouldn't have allowed it. He assigned his sons to capture her and bring her to him. But several sons who tried returned seriously injured.
So he was forced to assign Ace and Marco. That night, Ace was almost unconscious against some rocks with a broken arm and a concussion. T/N had defeated her brother. She was panting somewhat tired. T/N, I'm sorry, brother. Unlike you, Grandpa and that demon Akainu were my teachers. Marco Rio, I think he can't hear you anymore. Then you should go. Oh, you'll end up like him. How dare they set a trap for me like that? Marco approached her in the blink of an eye. I caught you once.
Marco kissed her The girl blushed back How dare you Marco Rio, I think I came to kidnap you You won't win Please, can you do something with that information?

Warnings: Violence, Blood and injury, Sibling combat, Emotional conflict, Kidnapping attempt, Power imbalance, Mild language
She was born in the shadow of fire.
Twin sister to Portgas D. Ace, granddaughter to Monkey D. Garp, daughter of Gol D. Roger—but Y/N never wanted to carry their names. So she built her own.
She wore a Navy uniform with pride, her coat a crisp white underlined with conviction. Vice Admiral Y/N. The youngest to ever reach such a rank. Trained by her grandfather, shaped by the brutal ideology of Sakazuki himself—and still, he never once knew the blood she carried.
They called her the Ember Admiral. A slow-burning flame that never lost control.
Only a few ever knew the truth.
For a while, she drifted between fire and duty.
Ace sent letters. Coded, brotherly, hopeful. And sometimes, Y/N answered them.
When she passed information to Whitebeard's crew, it was subtle. No one suspected the Vice Admiral of treason. A whisper here, a redirected shipment there. Just enough to keep her brother and his captain out of the worst trouble.
Then, she met Marco.
It was on a coast near Swallow Island. She had planned to deliver one last set of ship coordinates to Ace. But Marco came instead.
Golden hair kissed by sunlight. Calm in the way that made your pulse race. He didn't raise a weapon. He didn't need to.
"You're her," he said, eyes sharp, lips soft. "Ace's sister."
She said nothing. But she didn’t stop him from walking beside her along the shore.
That night, they talked under moonlight and ocean wind.
It was the first time Y/N felt seen—not as a soldier. Not as the daughter of legends.
But as herself.
Four months later, her voice broke with finality.
"I'm sorry. This is the last time. I can't pass you any more information."
Ace frowned. "Why?"
She smiled sadly. "I've been reassigned. Marijoise."
Ace turned to Marco, who remained still, his expression unreadable.
Y/N looked down. "It's not my choice."
They said nothing. But the air between them shifted.
When Whitebeard found out, his rage shook the ship.
"Marijoise?! That place is poison."
He had respected Y/N’s choice to join the Navy. Tolerated it for her brother’s sake. But to serve the Celestial Dragons?
No.
He sent his sons to bring her back.
None succeeded.
Some came back bloodied. Others, broken.
She hadn’t killed them. But she had made it clear: she would not be taken.
So he sent Ace and Marco.
It was a cold night when they cornered her.
Winds swept across the rocky coastline near her docked ship. Her crew had been sent to shore. Only she remained.
"You shouldn't have come," she said, facing her brother.
Ace already looked battered. His arm hung limp at his side. Blood trickled from his brow.
"I had to," he said hoarsely. "You're not safe."
Y/N stepped back, sword drawn. "Unlike you, I was raised by Akainu. I don't run from duty."
"Akainu's not family!"
She lunged. Their battle was brutal. Siblings born of the same fire, now burning each other.
Marco watched, silent.
Until Ace collapsed.
"Y/N," Marco said, his voice a low warning.
"Go back," she spat. "You shouldn't have come."
"I caught you once."
He vanished. Reappeared behind her.
Before she could react, his arms were around her, strong and certain.
Then he kissed her.
It was fast. Bold. Desperate.
Her body stiffened. Then softened.
"How dare you," she whispered, blushing fiercely.
He smiled against her cheek. "I think I came to kidnap you."
"You won't win."
"Then I lose with you in my arms."
Suddenly—
"Vice Admiral!"
Her Lieutenant Commander, the only one who knew her truth, burst from the trees and attacked Marco.
Steel clashed with phoenix fire.
Y/N snapped into motion, the kiss forgotten, instincts flaring.
Together, they fought.
But Marco was faster.
The last thing Y/N saw was her commander falling.
Pain bloomed across her ribs.
She collapsed into Marco’s arms.
As he lifted her, the small journal hidden in her coat slipped free.
He caught it.
A weathered logbook.
Gold D. Roger’s mark.
As he turned to leave, her lieutenant groaned.
"Wait…"
Marco paused.
The man spat blood. "You were right. Keeping her brothers away… that was smart. Pirates always steal what others love most."
He reached for his sword.
Marco stepped on his hand.
"You’ll regret not telling her you love her."
The phoenix said nothing.
"We made a good team," the man murmured. "But next time you see her… she’ll be a pirate."
Then darkness claimed him.
And Marco carried her into the night.
