Summary: Having had enough of how he was being treated in Bellwood, Ben Tennyson leaves for the country of feudal Japan. He meets up with a swordsman that has a cross-shaped scar on his left cheek, and decides to stay at a sword arts dojo that practices "Katsujin Ken", or "Swords that give life". Now watch as Ben Tennyson takes this new and strange world by storm! Takes place in Omniverse.

Leaving for Japan!


On a cargo ship heading for the distant country of Japan, there was a single passenger who wasn't a part of the crew. He had shaggy brown hair, neon green eyes, and pale skin. He was wearing a black and green shirt with the number '10' on the chest, a pair of brown cargo pants, and a pair of white and green sneakers. He also had a white wristwatch on his wrist that had a square black faceplate with a green hourglass mark in the center. He appears to be about sixteen years old, and has a look in his eyes that suggested that he was betrayed by everyone he ever cared about.

This is Benjamin Kirby Tennyson, wielder of the Omnitrix and hero of the universe. And about the whole betrayal thing? Well, you aren't too far from the truth. Earlier that day, Ben had failed in a mission to stop Vilgax from destroying a nuclear power plant. This wouldn't have been so bad if it didn't leave an entire town dead from radiation poisoning. This caused Ben to slip into a deep depression, which only worsened as his family and friends stopped paying attention to him all together.

Eventually, Ben left Bellwood without so much as a word of warning. He managed to get a ticket on a cargo ship to go to Japan. He figured that the rural area and change of culture might be what he needed to calm down and reflect on what went wrong in his life.

"Well isn't this an oddly familiar situation." Said a voice from a nearby crate.

Ben turned to look at the speaker, and saw that it was Azmuth. Azmuth was a Galvan that created the Omnitrix, and looked like a gray skinned anthropomorphic frog with bulbous green eyes, long appendages hanging from his upper lip which gave the appearance of a mustache, and was wearing a black and green toga with armor underneath it. His eyes held sympathy for what the teen was going through.

"Oh... Hey, Azmuth." Ben greeted halfheartedly.

"I heard about the incident from Maxwell. And I can most certainly say that I understand what you're going through." Azmuth said as he walked over to Ben.

Azmuth thought back to the beginning of the Hybreed's invasion. He thought about how he couldn't do anything to stop the temporary destruction of his entire race. The very thought was enough to send chills down his spine.

"The loss of all those innocent lives was hard on you, wasn't it?" Azmuth asked.

"I can still hear them. Their screams of pain and terror haunting every corner of my mind! I let them all down! I should've been there sooner!" Ben said with his face buried in his hands.

Azmuth was no stranger to this behavior. It was exactly how he was when he failed to save his own species from certain doom. But he also knew that sitting around moping wasn't going to solve anything! Besides, there was something that Azmuth needed to do that involved the Omnitrix.

"While it's true that you COULD have gotten there in time, I'm afraid the fact remains that you cannot change the past. Besides, I need to make an upgrade to the Omnitrix in order to help you fight stronger enemies." Azmuth explained.

Ben was puzzled by the Galvan's words, but paid attention anyway. Azmuth walked over to the Omnitrix, removed the core stating that it would only be temporary, and pulled out a green Polymorphic Crystal. He put the crystal into the Omnitrix, reattached the core and faceplate, and like that the Omnitrix began to transform.

It still stayed on his wrist, but the faceplate became circular and the band split to form what appeared to be four green 'Ultimate' spikes that met in the middle under his wrist. There were also two activation buttons on both sides of the dial, and the hourglass was now totally green.

"What happened to the Omnitrix?" Ben asked.

"I have upgraded it. It now has the evolution function of Albedo's Ultimatrix, but it is far more powerful! It can take your aliens beyond even the Ultimate forms!" Azmuth explained.

Ben was amazed by this new development! Now he had even more power than before at his disposal, and he had his Ultimate forms back! But that's when the Galvan scientist decided to break out some more news.

"However, I'm afraid that with certain aliens that are in your arsenal you can only change straight into their Ultimate forms. You won't be able to turn into their devolved states anymore." Azmuth said.

While Ben was happy about having new powers, he didn't like the trade-off very much. But he knew that there was nothing that he could do about this particular situation. Ben's eyes lit up with a renewed fire of determination, and vowed that he wouldn't allow any more innocent people to die because he couldn't do anything! The ship would be docking soon, so Ben picked up his supplies and went to the upper deck while Azmuth teleported back home.

Once Ben had disembarked from the ship, he started on his way along the winding paths of this country. He knew that the first thing he had to do was find a way to convert his American currency into Japanese fare. And right now, he doesn't have much money as it is. Ben was broken from his thoughts when he ended up bumping into someone.

"Oh, sorry. I didn't see you there!" Ben apologized.

It was a man who was apparently a samurai judging from his choice of clothing and the sword strapped to his left hip. He had lavender colored eyes with reddish orange hair, was a bit on the skinny side, and had a cross shaped scar on the left side of his face.

"Please, there is no need to apologize. This one was not watching where he was going. It is this one who should be apologizing to you!" said the strange man.

Ben was a little weirded out by the man's odd way of talking. It was like he was degrading himself by speaking in the third person, but Ben could somehow tell that this was a man he could trust.

"My name's Ben. Ben Tennyson. Who are you?" Ben asked.

"Kenshin. This one's name is Himura Kenshin." said the now-named Kenshin.


This is my new story, guys! I hope you all enjoy this, because I have put a great deal of effort into the creation of this chapter! Now, I'd like your honest opinions here. Should I have Ben learn the Hiten Mitsurugi style of kenjutsu, or not? And who should he be paired with in this story? Kaoru? Megumi? Or Misao? Please let me know in the reviews, or through PM. I promise to take all ideas into account!
