It was a silent night, only the constant beeping sound coming from a machine at his right could be discerned. Kyoya Kazuya, or at least the name of his "true self" is currently on the verge of death. His eyes swept through the gloomy room while his body is resting in a dissection table. Scars filled his body, at his right, a machine connected to it recording every change.
This night, the researcher said that this might be his last operation. They said that he can finally rest. Ironic, after spending time as one of them, helping them with different things, ensuring his safety and the so-called "happy life", they still can't at least spare his life. They even comforted him. Bah! Shameless.
It's not that surprising, though. The first time he was brought to this place, his life is bound to live in solitude while awaiting his death.
Kazuya lived his first life as the usual happy-go-lucky guy, living it to its fullest, not caring about anything but his happiness. Alas, nothing is permanent. He was diagnosed with cancer, his family can't support the bills, and his loved ones slowly cut their relationship with him. Even his girlfriend broke up with him.
Two years, he lived in the hospital for two tiring years. His body is barely alive, until one day it finally surrendered and brought him to his death.
Miraculously, he was reincarnated. He thought that maybe God is watching him, he decided that he wouldn't let this chance pass. He would live his life from a different angle, he decided to be a police officer. To live a righteous life, abiding the law while bringing justice to the citizen of the world. It's also his way to thank God for giving him another chance.
Alas, things aren't what he expected. His father in this world is a gambling addict while his mother is a slut, prostitute, and whatnots. To pay their debts, they would bear a child and sell it for money. At four years old, he was transported around the world. Then at a certain time, he arrived at a laboratory, laboratory researching about human biology. The researchers there always says "this is for the sake of humanity", which is clearly bullsh*t.
Then they discovered that Kazuya's brain is a unique one. It can process things faster than other kids, thus they decided to nurture him. They teach him science and all those stuff, while Kazuya helps them with menial tasks at the lab.
They also trained his body, along with the other kids. They taught them swordsmanship, applying the training from the ancient books they discovered.
At first, the kids and Kazuya didn't care and just continued their training. They grow as a fine warrior, with huge builds and strong muscles. Thanks for the arduous training that is. They matured and thought that they are trained to be a private army.
Then one day, the researchers held a Battle Royale. They are all startled, clearly afraid of hurting their companions. But their motivation piqued once they heard that the ten survivors will have the privilege to live a normal life after ten years of service.
On that day, everyone turned cold-blooded. Willing to kill even their friends, not trusting even their closest friend. Then the day came, and ten people survived. Out of the 1,000+ people, ten survived. One of these people is Kazuya.
However, the promised prize is just a mere illusion. The ten of them were knocked out, once they woke up they found themselves strapped on a dissection table. And there, the true suffering commenced.
Turns out, this laboratory is researching how to improve humans. To be specific, it is improving the human body. They were curious about how ancient people can live a longer life, finding the easiest and time-efficient way of extending life span.
However, there are no ancient people alive in that day and age. So decided to make one. To ensure the quality, they made them kill each other and pick the strongest and wisest of them. Of course, the wisest is Kazuya thanks to him helping the researchers with some prior research.
There, twenty years have passed. The long tiring torture is almost ending, for Kazuya's case. Now, he's on his last breath. Reminiscing, his first life where he's happy until his next life where his lonely, hurt, and sad.
Two minutes have passed and he breathed his last. His mind spun, and his soul went straight to the void.
...
Just like when he died the first time, the first thing that happened is that he regained consciousness. Not likes his second life, he wasn't a baby. At least for what he felt. He tried to open his eyes.
What he saw a blurry image of a sword laid over an alter. His body full of wounds, and is currently laying in a pool of blood. Then he tried to stand up, even with a tired body plastered with wounds. He shrugged, being used from the pain.
He then scrutinized his surroundings. He can see almost nothing as it seems that he's in an unlit cave. A cold wind swept on his wounds while he could hear footsteps nearby.
Struggling to stand, he slowly walked to the altar where the sword is laid. Then without hesitation, he picked it up. Thinking that the owner of the footsteps may be hostile. At least in this life, he could try to defend himself.
Strangely, just as his fingers touch the samurai-like sword a voice sounded in his mind...
'Seems like it's my time to be a protagonist.'. For the first time, his face formed a grin. The information about his soul being an Immortal is already old news, he knew it in his second reincarnation.
"System, permission granted!" he exclaimed, now gripping the sword as he leans on the altar.
<...>
< Complete! >
< Welcome to The Last Swordsman System. I'm the system, I'm responsible for guiding to complete the system's goal.>
"Okay then, I'm in. What's the goal by the way?"
< To restore the glory of Swordsmanship! >
"Uh, okay. System can I access the owner of this body's memory?"
< Memory Transfer Initiation... >
Soon, unknown numbness followed by pain swept to his mind. However, rather than being in pain he just shrugged. Being a lab rat for twenty long years, pain is the last thing he could feel. Or let's just say, he's used to being in pain.
Unknown memory then lingered on his brain. The young man is also called Kazuya, but his last name is now Red. Kazuya Red, 18 years old. Brown wavy hair, gray eyes, pointy nose, and square jaws. Typical adonis, if not for his weak build he would be the hot guy that is often in-relationship with the cheerleaders.
He lived with his family, not so rich but can sustain two children to go to a good school. This world is highly developed, well one of the many worlds. The World is called Zerth.
The current date is 4020 of early April. People in this world are highly developed in terms of technology. Inter-galactic Travel is old news, interacting with aliens is the norm. Some even lived with humans.
However, this exposed humans to radiation called "Zax". Giving them unknown "superpowers", which is now called Esper ability. Espers are everywhere, only 1.3â„… of the human population is not an Espers. And almost all of them are alien hybrids.
Well back to Kazuya, his predecessor was exploring this cave for training purposes. Unfortunately, he was almost eaten by wolves. If not for his ability, [ Dimension Rift ], he would die in just seconds. However, this exhausted his energy as its a high ranking ability. If not for his arduous training he wouldn't activate it even once.
After stepping out of the dimension, he was brought to this altar and soon bleed to death. That's when Kazuya's rebirth took place. And now considering the situation, he decided to get out of this place.
Looking at his body, he thought that even with his proficiency in sword it wouldn't still work. Though he can ignore the pain, his movement is still too slow. Thus he asked the system if it could do something for help.
" Oh? Then let's open it," he replied, intrigued.
< Opening Gift Pack... >
< [Insta-heal Injection] and [ Sword Modification ] >
"Oh! That's nice! A healing item.". Then he asked the system for it, and a four-inch syringe appeared on his left hand. A green liquid inside it, without hesitation he injected on his self. Immediately, a warm sensation filled his body, several claw wounds clotted in visible speed. In just three seconds, he can now use the sword without feeling the tired in one swing.
Fully healed, he asked the system what the sword modification is. Then a summary of it was voiced by the system.
< [ Sword Modification ] is a one-time thing used for enhancing your sword. Once you used it in a sword, the sword would be bound to you and you're the only person who can use it and its ability. The modification has no certain limit, however, remember that the more powerful the sword the higher the requirements for using it. >
Kazuya pondered for a moment, then he nodded. He sat on the altar and activated the [ Sword Modification ], using the blunt sword for it.
He then entered his consciousness and started the modification. First is the appearance. Since this an advanced technology era, he decided to make its appearance have a certain sci-fi feel. He formed it as a long sword, colored in white while the edge has a blue hue.
Then next is abilities. The first ability is [ Molecular Distortion ], this ensures its sharpness. With this, everything it touched would be cut in half excluding none.
The second ability is [ Energy Manipulation ], this is for long-range attacks. When activated, each slash would send an energy beam in form of a blade. Using his psychic energy of course.
And with that, his simple yet powerful blade is done. All he needs to do is name his sword, which he named Kozo. This is his younger brother's name in his first life. To remember his first life, and to remember who he once is, he decided to name it the same name as his brother. His closest and supportive brother.
Finally, the modification finished. He exited his consciousness and as his eyes opened the old sword floated in the air. Then it spun and spun, magically after it stopped it became his official sword, Kozo.
White blade, blue hue at the edges, and the handle is ink-black. Excitedly, Kazuya grabbed it, and instantly the edge where a blue hue could be seen glowed. Then he tried to slash it in the air. A trail of blue electricity followed the white sword! Sci-fi feel! Hah!
