One Piece System
A SERIOUS FIGHT

"King of the Enma Monkey!!!"

There was a small burst of smoke from where Luffy touched the ground and when the white smoke disappeared, the people around and GARP saw what happened. At that place a humanoid monkey had appeared. The monkey was twice as big as a normal human. Even the large Garp looked small in front of the monkey that appeared.

It's Enma. The summoning monster from Sarutobi Hiruzen and now the monster from Luffy. Since he has the character of Hiruzen then of course Luffy will receive all the inheritance from him. Luffy had tried using this when the synchronization had reached 90% and he was overjoyed because it was truly Enma. Even Ken himself was surprised by this because he never expected that Luffy would be able to do such a thing and the system would even let this happen.

In all of their previous fights, Luffy had used both hands or the iron pipe they had gotten from Terminal Gray but after the appearance of Enma, the, Luffy has dedicated most of his time to fighting Enma's transformational state, which is a stick that can change its size and width in commands.

Luffy struggled at first but then he mastered it. Enma looked threatening and ruthless with battle scars on her body. It had white spiky hair and wore standard ninja clothes. In fact, Enma has the head band of Konoha up to. He knew that he was not in the same world anymore because Hiruzen had died, but he was also happy that now he had made a new friend that he liked.

In the past year, Enma personally trained Luffy and Ken also talked to him about this world. This surprised him even more as he learned of this new level of world power, but once again he was looking forward to seeing a new world.

And today for this battle, Luffy did not hesitate to take her. It's going to be a tough battle and they have to be serious.

"What'sthis? A stoat? How did he show up? I don't feel anyone near me with this much power." GARP was a little confused to see such a big monkey appear. Enma looked like a stoat but she had never seen a stoat of this caliber before.

"Son, why did you call me? I thought you were traveling... Uh!!!" Enma looked at Luffy but then she felt the eyes of a strong man staring at her. Enma turned around and looked at GARP. He could sense that this person was not easy and there might be a fight.

"Grandfather Enma, he is my grandfather and we have to stop him when we run away" Luffy said.

"escaped? Are you sure we can't beat this Ken kid?" Enma surprised. Luffy had never retreated from any battle until now. And even when he trained with her, he showed incredible prowess in battle, but here Luffy thought of escaping. Luffy just shook his head.

"Haha... I didn't expect my own grandson to be in a relationship with someone from the Mink Tribe.. As expected of my grandson. Now who are you?" ask GARP.

"I'm the summoning creature, Monkey King Enma and I don't think you even know what it means, but I think we have to fight it out for this kid to achieve his dream." enma said and with a puff of smoke Enma disappeared and transformed herself into Adamantine Nyoi. A large black stick with yellow ribbons on both sides.

The black stick fell into Luffy's hand as he twisted it at high speed. I don't know why the stick feels alive in Luffy's hands. Meanwhile, Ken's body was enveloped in lightning. GARP doesn't understand what just happened. The monkey of the ermine tribe? Black stick? Ken has the power of lightning? And two guns?

Was he so ignoring his granddaughter that he didn't even notice such a big change. He felt a little guilty but again no matter what was going on. They will go with him anyway. He looked up and saw the black clouds and could easily tell that there was some sort of reaction from Ken's power. GARP thinks Ken may have eaten the fruit of the lightning logia.

"Kids, do you really want to fight me? Luffy did you forget how I disciplined you? Ken, are you underestimating me too much?" Garp said while unbuttoning his beach shirt. He's getting serious!!

"I remember Grandpa but I always said that I would become the Pirate King and become a great pirate like Shanks." Said Luffy while pointing Enma towards the GARP. Ken turned his hammer at high speed.

"Luffy, do you remember the trick I used to do before?" whispered Ken.

"Yes! Do you want to use that?"

"There is no other way!!"

"Will it work?" Luffy was a little skeptical of the trick that Ken mentioned. Although he had heard a lot about it, he was still more afraid of his own grandfather.

"Trust me. You just need to slow it down and I'll do the trick. And also make sure the surrounding marines are taken care of."

"All right!!" Luffy said as he ran to the side to take down the marines who had just stood up. Although these marines won't be a concern to Luffy and Ken, owning them will probably be a problem later on. The marines stiffened when they saw Luffy approaching them. They saw him as a child but when Luffy knocked down the first marines with just a self-growing wave of 'sticks', they almost wet the bed.

One punch! One Knockdown!

Meanwhile, Ken takes his Stormbreaker and jumps high to fill himself with lightning and continues using momentum and attacking Garp with lightning and physical strength. The surroundings changed from sunny side to gloomy as Ken made his first move.

GARP put a smile on his face!!
