There have been some comments about how they didn't like the personality of Kenshin being 500+ years old and talking with Luffy and joining him. Personally I don't care what you think and I sure don't give a damn about it. So, if you don't like don't read it. Just don't fill the comments or reviews with your biased and hateful remarks.

It has been a day since Kenshin left Raijin Island where Kenshin and Shanks have sparred. While running in the air, Kenshin thought, "Man it's frustrating". There was a slight frustration on Kenshin's ever calm face.
"I knew that Yonko were powerful but to think there is this much of a gap between us. Shanks only used physical strength and Sword mastery to beat me. If he would have used his Haki which I am sure is already at the peak of Grand Master level, he would be about 100 times stronger.
It's frustrating but it's fine. If there were no challenge then it would have been boring. If nothing else happens then I am sure within 5 years I will surpass him. How many years it has been when I felt my blood boil", said Kenshin. At first, he was frustrated but he soon maintained his composure.
Yesterday- Raijin Island.
"Captain, how was the kid", asked Lucky Roo as he watched Kenshin flying in the air.
"Strong. Very strong. He is only 16 and has the same strength as the top 10 strongest within our ship. I am sure he will only get stronger in the future. Within a few years, the balance that has been maintained for so many years will break. Great War is coming. It's time to change the rulers. Men prepare yourself for the war", said Shanks looking towards Kenshin.
When Shanks crew-mate heard this, they were shocked. This was the first time he has praised someone so much and Shanks who has always tried to maintain balance is now picking sides of a kid in the war.
But they nevertheless followed the order of their Captain.
Back to Kenshin who was flying or running in the sky. Kenshin saw a news coo flying towards him. Kenshin just stopped, took the newspaper and paid the amount. After which Kenshin went down to read the newspaper.
Kenshin saw "3D2Y" has happened even though Ace was saved. The remnants of Whitebeard Pirates were fighting against the other pirates encroaching their lands. And many more such things.
White Kenshin was just casually standing on the surface of the water and reading the newspaper, a pirate ship was near him and for some reason, their Captain decided to bombard toward Kenshin.
Kenshin who was reading saw bombs coming towards his direction by using his Kembunshoku Haki. Kenshin just released his ki to make make a barrier that pushed the bombs in the direction where they came from. The poor pirates signed their own death warrant.
The bombs came toward their direction destroying a major portion of their ship, many were also injured. The captain was scared looking at this. After a few minutes, Kenshin finished reading, then looked towards the pirate ship.
Kenshin made a very compressed vortex of ki and threw it towards the pirate ship. The compressed vortex when contacted the ship exploded and destroyed everything near a 100-meter radius. After that Kenshin flew towards the next island using his Log Pose.
While running in the air, Kenshin formulated a plan to improve his strength. Kenshin thought, "My ki will increase as I am forever using DDD and my control is perfect, so I don't have to worry about it. The main matter to improve is my physical strength, Haki and sword mastery. So in the next 2 years, I will use only these 3 to fight the stronger opponents".
Like this time went flying. It has been about 2 years since Kenshin came to the New world. He went from Island to Island to fight with strong people. Kenshin was surprised to find about many peoples with strength comparable to Yonko Commanders in New World.
In his journey, Kenshin fought people with the bounty from 1 to 2 billion bellies. In this time Kenshin's sword mastery went to low Legendary level and his Haki went to mid Legendary level. Kenshin also didn't forget his physical training.
Kenshin would go to deep underwater about 12 to 13 km deep and practice Sword Arts while applying Haki on his sword. This way Kenshin improved his physical strength, Haki and sword mastery at the same time.
In this time Kenshin's body also changed a lot may be due to One Piece world or some other reason. Kenshin height increased from 1.9 meters to 2.3 meters. Though it is not much in this world, his height increased 30 cm more than his previous life.
Kenshin's current strength would be comparable to the Shanks of 2 years ago even after using his ki. (Shanks physical strength and Haki also have increased in these 2 years, so as every bodies strength)
One of the regrets of Kenshin was that he didn't found Toto Land, Wano or Zou even after roaming around New World. Kenshin just sighed and thought that he didn't have the protagonist aura, so that is why he couldn't find these places.
Kenshin's ki also improved a lot in these 2 years due to DDD being such perfect cultivation and also due to the fact that Kenshin ate hundreds of thousands of sea kings and monsters of that level and using Iron Stomach techniques, he converted them to ki. (If compared as to how much ki Kenshin currently has, then it would be about 5 tailed beast level if we compare with Naruto World)
In these two years, he was lucky to met Mihawk in a competition where much strong personnel from New World had come. After that, he fought with Mihawk for about a month every day. This soared his fame to another level.
It was due to fighting with Mihawk that he is at low Legendary level otherwise he would have been almost at high Grandmaster level. Mihawk who fought with Kenshin also benefited from the fight as he was able to reach the Legendary level and create his own sword domain.
In these 2 years, Kenshin's bounty also increased many times and he also got the new title "Blood Devil". It was due to him killing pirates and many tyrannical rulers he came across. Kenshin's current bounty is 1.7 Billion Bellies.
Kenshin's sword developed a sword spirit. After the development of sword spirit, ki and Haki conductance of the sword has increased by tenfold. It also became fully black in color. Kenshin changed the name to 'Izanagi' (Shinto god who can create and destroy worlds).
He finally found scabbard to fit his sword and also that looks cool. The scabbard was a black color with red and dragon and phoenix made onto it.
Now, currently, Kenshin is running in the air towards Sabaody Archipelago to join with Luffy. At first, he didn't want as he wanted to have his own adventure. But due to his nature, he couldn't make any friends other than Mihawk who is almost like him 'loner'.
So, he wanted to join and make friends as he is improving and will become a powerful martial artist but being there alone without challenges is no fun. So he decided to join Luffy as they will become strong and Luffy and gang always attract trouble which will help Kenshin to fight with stronger opponents.
As soon as he landed on Sabaody Archipelago Kenshin went to greet Rayleigh and Shakky as Kenshin liked them from the anime as well as personally also.
"Ken-chan, is that you? Welcome and what will you have", said Shakky.
"Yo Kenshin, you seem to be causing a storm in the New World", said Rayleigh.
"Hello, Shakky and Rayleigh-san. I will have some steak and Bacon", said Kenshin while taking seat.
While sitting Kenshin looked and saw many injured people there.
"Shakky, you don't have to beat them so much to rip them off their money", said Kenshin.
"No ken-chan, they are injured while protecting Monkey-chan's ship", said Shakky. It was then Kenshin remember them as Duval and gang protecting Luff's ship.
"Ken-chan what are you doing in Paradise. Did you finish your adventure", asked Shakky.
"No Shakky, I am here to take Luffy's offer and join his gang on an adventure", said Kenshin. This surprised Shakky and Rayleigh.
"Why do you want to join Monkey-chan's gang", asked Shakky curiously.
"Nothing special I just want adventure with some friends and I like Luffy's personality so his crew must be nice. I am bored of being alone and if I stayed alone I will be like that stupid faced Mihawk", said Kenshin. Hearing this Shakky and Rayleigh just were surprised a bit, then laughed slightly.
"Ken-chan, you have changed. But it's good. Being lonely is not great even though you may be stronger", said Shakky while Rayleigh also nodded.
As they were talking Sanji came to the bar. Like in the manga he talked with Shakky and Rayleigh a bit and also thanked Duval for protecting their ship. He also asked about other members of the ship to Shakky.
