One Piece System
WITCHCRAFT

Hachi relentlessly slammed all his swords towards Luffy to slash at him. No warning, nothing. It was because Hachi felt Luffy had broken his trust and insulted his food. As the 8 swords were several inches away from Luffy's body, Hachi heard a voice in his ear.

"Mother"

One sword blade that looked like it was burning in flames was so hot that even before the sword could touch the hachi sword, he felt its burden from a distance. Hachi who was proficient in 8 swords wanted to avenge the sword attack that was about to land but it was too late.

It was Zoro who used the first form of solar breathing and stopped Hachi's attack. Two attacks from two different people and the fishermen around along with several marines for the first time saw the pure brilliance of two people they had never seen before.

Sanji's kick breaks Arlong's bone and Zoro's sword breaks all 8 of Hachi's swords. There was complete silence after this. Only the waves that hit the pool were all the sounds that people around could hear.

"It's not your place to tell us who my friends are and who's not. Nami is our friend and that's all I care about. I may not be able to fly, I may not know how to be a good swordsman or may not." know how to navigate and cook. But I knew that my friends would be there to help me on my journey." Luffy said as he placed his fingers in a triangular shape and placed them near his mouth.

"Katon: Gokka Mekkyaku" (Fire Style: Great Destruction)

*cashhh*

Luffy blew the air from his mouth and the air passing through those fingers unleashed an extremely majestic burst of fire towards Arlong and all his crew. His movements were so fast that they did not even understand what had just happened.

Arlong who was already in pain had to run and dive into the pool to avoid the barrage of shots that this Straw Hat man had just emitted. But others are not so lucky with it. Other crews of Arlong pirates and even Captain Nezumi block the fire.

A majestic release of fire like this was enough to completely burn the people around him. This jutsu was somewhat exclusive to the Uchiha clan but apparently Luffy had already learned it. It shows how good his inclination is towards fire. Luffy's devil fruit really plays its part here.

This move surprised Ken. Luffy is very good at learning new techniques and surprising them. When Luffy studied the second tooth, it shocked everyone. Now it looks like Ken is also on the other side of the trick.

Luffy was really made for battle. After the fire slowly reduced, Sanji slowly advanced and gave a nice kick to Luffy's head. Luffy was blown away by that because he didn't expect Sanji to do that.

"Bakma.... If I don't have fire resistance, I'll die there."

Sanji is not really angry but is only annoyed that he is also the victim of Luffy's attack. It was good because his new body gave him fire resistance along with using fire through his legs. Everyone can see the destruction. There's nothing left. Chairs and tables burned down.

Smoke shot out from the people's bodies as their entire bodies were charred. Thankfully this is a One Piece world and people have a hard life, otherwise they would have died in Ken's previous life.

Luffy doesn't mind Sanji hitting him. He put his straw hat back on his head and smiled like a fool like Sanji.

Meanwhile Hachi cried to see his friends lying half dead. He was angry and sad. Angry at not being able to save them and sad that his friends are on the verge of death. He fell to his knees as he picked up one of the crew members on his arm and started crying.

"What are you crying for here? Not that they're dead." Ken was annoyed with Hachi's shout, Hearing that, his crying instantly stopped. To see if what Ken said was true, place his ear on the chest of a fellow human fish, only to hear his heartbeat.

Hachi looked happy to see his friend was fine. Seeing Hachi's stupidity, everyone put their hands on their foreheads. This person was completely desperate.even Nami did not feel like doing anything to Hachi seeing how easily he was manipulated.

It was Luffy who nearly killed his friends, but a few words from Ken made him feel Luffy and the others were even irresponsible. Patients with short-term memory loss.

Meanwhile Sanji came forward and looked towards the pool. He knew very well that Arlong was fine and hid in the water. Since water was not his power, he had to wait, but he strongly doubted that Arlong would appear.

"Oi's a sniper. Can you find him?"

Sanji looked at Usopp who was trying to use his glasses to see Arlong's whereabouts. He was happy to see how powerful his crewmate was and wanted to help but how could he find someone this way.

"Do I look like a fishman to you?"

"With your nose, I really think that you are a fish-man."

"What did you say?"

"You heard me!! Nose - kun."

"Stop you two, I'll find Arlong." Nami said as she took out her wand and muttered

"Revelio"

An invisible force was emitted from the stick and slowly entered the sea water. Immediately a very blurred image of a person swimming in the water was seen several meters from the edge of the pond.

That's Arlong.
