Sea Witch (One piece x Witch! Reader)

A new crew member, the sea witch, joins the crew.

Zoro just heard something coming towards them. He turned to look at the source of the sound and saw Baroque Work's ships. The others who had heard the strange water waves also turned to look.

"Baroque Works! Those are the Billions ships!" Vivi let everyone know

"Those guys again?" Luffy looked over and remembered that they were the ones who messed with him and his brother as they made their way to the Going Merry.

'Looks like he's getting into trouble again,' (Y/N) sighed slightly. While everyone ignored the sea witch, she removed the straw canopy leaving only the pole that was actually a weapon wearing a gold-patterned white sheath.

"I'll handle it."

"Eh?" they all turned to the woman walking up to them, who in her hand was stripping the sheath to reveal a large needle-shaped sword.

"Where did you get that sword?" Usopp pointed at the sword, he began to sweat. The woman smiled at him and replied.

"It's the umbrella I'm holding~" she said pointing to the canopy that was actually a straw hat. "That one was a straw hat. When put together, it becomes an umbrella, cool right?"

"So cool~!" Luffy and Chopper's eyes lit up. The woman chuckled at their childishness.

"Then let me go with you." the girl turned to Ace who smiled at her. She smiled at him and nodded before the two looked at the enemy ships. The two of them jumped down to the bottom causing everyone to run and look down. Ace rides a raft shaped like a yellow crescent moon towards enemy ships, using the fire of his own power to turn his feet into fire to power the raft. (Y/N) turned the sea into a path and ran at a rapid pace, faster than Ace who was the first to leave.

"W-Who's that woma-? Wait- She can walk on water?!"

"Why would you care?! Defeat her with Fire Fist Ace!" as Ace approached the enemy ship, he suddenly jumped into the air with great force, sinking his raft as the woman dived into the sea. The enemies were alarmed to see the black-haired young man turning into a ball of fire that shot towards the back of several ships. The woman emerged from the sea and extended her sword grip. Ace transforms from a fireball to human form, his feet colliding with a floating raft just above the sea. The two turned to look at each other before grinning and looking at the target in front of them.

"Fire Fist!" his fiery fist shot towards the ship.

"Massa D'acqua!" the air force that her sword swept out caused a force similar to the air pressure of a deep sea mass, that air force colliding with the enemy ship. In the blink of an eye, many of the enemy ships had turned into rubble, the force of the wind caused Straw Hat's ship to retreat slightly. Everyone, including Ace, was shocked to see such a powerful force. Before the flames of the Fire Fist followed and burned the pieces of wood that were still floating in the air.

'What is that power?! She's as strong as Pop...' Ace sweated before looking at the woman who was also looking towards him.

"Let's go see everyone!" she smiled at him as though she wasn't the same person who released a demon-like power. He nodded slowly before following behind her.

"Woohoo!"

"(Y/N), how did you do that?! Scary~!"

"Ace is one of us now!" Straw Hat, Long Nose, and Reindeer cheered for the two with toasts.

"Who said I was joining you?" Ace looked at the three boys who were not paying attention and drinking from the wooden cups. (Y/N) next to him giggled, amused by the sight.
