An Ōtsutsuki on the sea(Op male reader x ONE PIECE)

Laboon

NO ONE'S POV:
It was finally time for the Straw Hats to go up Reverse Mountain, they had gotten awfully closer the entrance and there was no turning back now. (Y/N) was steering the ship at the steering pole to the best of his ability.

"Nami do you see the entrance, it should be a crack in the mountain!" (Y/N) called out from the gallery room of the ship. Since he had decided to get the crew to the mountain, he had been steering the ship for the last hour until they got even closer to the mountain.

"Yes, I see it! Keep going straight ahead like we're going now." Nami said as she looked through a pair of binoculars. She was quite surprised by how reliable (Y/N) was compared to Luffy seeing as how Luffy didn't know how to navigate or cook but it seems like his brother has more skills that can be put to use around the ship. "Everyone come look!"

"I can't believe it's going up towards the sky!" Zoro exclaimed as he saw the water going up the mountain. Normally such a thing would be deemed impossible or just fiction but to actually see it was quite surprising to the swordsman.

"Oh just wait until we get to the Grand Line, you're gonna see way more surprising things. I wonder if I'll be able to take you guys to one of my favorite islands along the way. There's some old friends I wanna see again." (Y/N) said as he as leaned against outside of the gallery. He was quite happy thinking about all the people he's met throughout the Grand Line. "Luffy you'd be quite interested by them."

"Wait a minute if you're here than who is steering the ship?!" Nami yelled at the masked individual. She had thought he was responsible but now it's starting to be clear how similar he is to Luffy. "Get back to steering!"

"There's no need for that beautiful, I'm still steering while I'm out here. Just take a look." (Y/N) said as he pointed to the gallery where the steering mechanism was located at. The others would see another (Y/N) keeping the rudder going straight as they sailed towards the Red line.

"How can there be two of you?!" Nami yelled with a slight blush on her face. She had been used this by Sanji but something felt different hearing it from the masked individual.

"Yeah how?! Did you eat a devil fruit?" Usopp called out as he saw the duplicate of (Y/N) alongside the others of the crew. He was trying to think of what fruit the white haired male could've eaten. "Did you eat the double double fruit or something like that?"

"Oh no, it's just one of the many things I can do. It's quite common among the people of my birthplace." said the original (Y/N). He made the shadow clone hand sign. "Shadow clone justu!"

(It's just one Y/N) that was summoned, don't wanna sink the ship)

"That's amazing!" Luffy yelled as he had stars in his eyes. The rubber man was enjoying seeing the shadow clone. He poked the clone only for it to disappear in a cloud of smoke after he poked it's cheek. "Woah it's gone!"

"Luffy, I've shown you this technique a long time ago. But anyways we're about to go in the Grand Line so let's all make an oath right here on what we plan on accomplishing ok?" (Y/N) said as he placed a barrel in the middle of the ship. "After all you guys only enter the Grand Line for the first time once so it's a memorable moment for you all!"

"Sounds like fun!" Luffy said as he stretched his way over to the middle of the ship. He was excited because this was one of the first major events that would lead up to him becoming the king of the pirates.
