One Piece/Blue Exorcist: The Fourth Brother

What if Rin was born in the One Piece universe and was the fourth member of ASL?

A teen landed on their ship in the darkness of night.

Everyone was asleep, but one swordsman sat in the Sunny's crow's nest, asleep, but alert.

His hands itched towards his swords on his hip, his one eye opening a crack.

He leaned forward and looked toward the deck, eye following the silhouette that circled the wooden floor.

He slipped his swords from his sheaths, leaping down and aiming to cut the person's neck.

The figure swung around, dodging backward with a grace and speed that had the green-haired man impressed.

"Who are you?" Zoro growled, his voice slightly slurred from the sword in his mouth.

The bright moon in the sky illuminated both of them as the clouds parted and Zoro was able to see the figure better.

It was a teen, a male one at that. His raven hair looked like Luffy's, but thicker and a bit longer, along with a blue tint that Zoro doubted was from the moonlight. His bangs swung against his forehead from the sea breeze, but somehow left his bright blue eyes visible. He was about 5'8", standing proudly. His ears were pointed and his canines were sharper than a normal human's. He wore a pair of blue jeans, a chain hanging off one side of the leg, a pair of black boots, and a navy tee.

The male raised an eyebrow at the swordsman. "Pirate Hunter Zoro, Swordsman and First Mate of the Strawhat Pirates."

"Who are you? What are you doing here?" Zoro demanded, swords tight in his hands.

The male sighed, eyes dropping to his feet. "My name is Rin, and I need to talk to your captain, Monkey D. Luffy."

"What do you want with Luffy?" Zoro asked tensely.

"Zoro? What's all the ruckus?" A female voice asked angrily. "We're trying to sleep!"

Rin turned to look at the female, examining her long, orange hair and melted chocolate eyes. "Hello. You must be Cat Burglar Nami."

Nami's eyes widened. "Who are you, and what are you doing on our ship?"

"As I've said before-" Rin was cut off as he jumped backward to avoid getting kicked in the face by a certain blonde chef.

Rin narrowed his eyes and huffed childishly. "I don't understand why you guys keep asking me questions, but won't let me answer them. So rude."

By now, the whole crew had woken up except Luffy and eyed the stranger. Rin examined them all. "Black Leg Sanji, Sogeking, Cotton Candy Lover Chopper, Devil Child Nico Robin, Cyborg Franky, and Soul King Brook. Pleasure to meet you. Now, I'm looking for Monkey D. Luffy, so if any of you would be kind enough to show me to him, then I would really appreciate it."

"Like hell we're telling you where that shitty rubber is!" Sanji barked, biting his cigarette in half.

Rin raised an eyebrow. "Look, I-"

"Rin?" A quiet whisper sounded behind the whole crew.

They all whipped around to see Luffy, standing there with wide, shocked eyes. Rin smiled at the straw-hatted boy. "Hey, Luffy. Long time, no see, huh?"
