~~~~~~Renz POV~~~~~~
"It has been one and a half year since I came to this fantasy world that can only be seen to manga and anime. I was devoted on focusing to strengthen my body in order to survive. I have been training and was able to unlock the tri-colored Haki, I am now at the basic level of armament haki, intermediate level in Kenbonshoku and Haoshoku Haki. I also taught Mants Busoshoku Haki as I noticed that his intellegence far surpassed those ordinary Giant Bugs so, I taught him haki and also I want to have someone to spar as to create more techniques and get used to the feeling of using haki"
~~~~~~~POV End~~~~~~~
Renz was able to fully used Kenbonshoku Haki and its scope has reached 500 diameters as well as Haoshoku Haki. He also reached the bottleneck in Busoshoku Haki which will soon be able to step into intermediate level.
Previously, 10 months ago, Renz who has unlocked Kenbonshoku Haki, has sarted to take another step and change his training routine and focused on unlocking armament haki.
For almost 3 months he have been training, he has several times failed on unlocking as he can't imbued his arm with spiritual energy. He thought of applying his natural energy and concentrated it into his arm and tried to solidified it, but to his disappointment it only exploded. He tried and tried and the he only acquired the same results from before.
Accidentally, while trying so hard to comprehend how to imbued his arm, a different energy has flowed through his arm and it darkens a little bit but it was unstable as it keeps going on and off.
Renz who noticed that his arm has changed into black color and a little transparent at that, suspect that it must be Busoshoku Haki, He tried to used his spiritual power and concentrate it to his arm and to his surprise, it seems that his theory was right after all. But he can't seem to properly utilize it, so he trained while punching on the big trunk of the tree. "BANG!" a large crater has formed on the trunk of the tree.
"It seems that there are two energies residing on my body, one was the natural energy of my body which has an unknown origins and the other was spiritual energy which can be applied to be able to imbued armament haki on my arms" Renz said to himself as he was still experimenting his new found power.
Renz was still training his armament haki and a months of training, he finally got used to it and has reached the peak of basic level.
[Back to present time]
Renz was taking a rest from the sparring with Mants, he was thinking of what to do next. He was strong enough that this environment was insignificant to him as it didn't pose a threat to him anymore.
"I should think of another method there is still 1.5 years left before the start of the canon" Renz said to himself.
While thinking of something Renz, suddenly recalled that there was still one last thing that he hasn't been able to touch.
"Arghh! How can I forgot about the crescent-shaped sword, I should start using it as I have grown a lot stronger than before, I think I'm ready to use it now. I'll make sure to tame that cursed sword, Yosh! Time to train my swordsmanship" Renz rush to the cave where the crescent-shaped sword was stored in.
He arrived at one of the isolated part of the island, he unwrapped the crescent-shaped sword and touch the hilt of the sword.
Instantaneously the ominous aura envelopes him making his head ache again "Arghh! This shitty sword" Fortunately, he can endure the pain since his mentality and body strength has been growing a lot.
Renz imbued his arm with Busoshoku Haki "SHING!" the pain on his head has decreased but it still not stop from trying to consume him. So Renz also used his Haoshoku Haki "SWOOSH!" a huge shockwave was released on Renz body as a distortion on atmosphere can be seen."GAAAAAH!!!" Renz shouted as he released his Haoshoku Haki.
"BOOOOOOOOOOOOM!!"
A large explosion has occured between Renz and the crescent-shaped sword, as the ominous aura has been suppressed by the pressure of Renz and slowly dissipated reaveling it's black color and sharp edge.
"Huh, finally I got to make you mine KEKEKEKEK!" said Renz as he wipe his sweat and revealing his devilish grin and laughed.
"Wow, this is so cool it's much lighter compared before and I feel a lot comfortable weilding it, as if it is one with my body like a extended arm" Renz said as he was observing the crescent-shaped sword on his right hand.
"Well, I should train using this sword in order to learn new techniques" Renz exclaimed excitedly.
"Oyy!! Mants come here!" Renz shouted at the sleeping Mantis near the cave. The Mantis heard his voice and woke up from his slumber and went to the direction of Renz.
"Mants, I am going to train and I need your help" The Praying Mantis who was listening to Renz got sweat from his body as he was remembering those past training they did which makes his body aches a lot, but he did not refute as it is someone stronger than him ordered, he can only follow his command so he just nodded and await for his instruction on what kind of training they will do.
"Okay Mants! Where going to train for 6 months, you are going to fight me as I need to learn swordsmanship and create swordskills" the Praying Mantis just nodded helplessly.
Just like that, 6 months have passed and Renz have been able to learn how to use a sword and was able to create two swordskills. He was able to improve his tri-colored haki too. One, Kenbonshoku haki has reached a bottleneck, which was one step closer to reach advancement level, where he will be able to take glimpse in the future for a certain amount of time, his Haoshoku was in the middle stage of intermediate level, while his Busoshoku haki was also the same level as his Haoshoku.
Renz went to his training area which was full of large craters, as if there was a large bombing has occured on this place, Renz who was standing, hold his sword and used one of the recently learned skill. Renz concentrated his natural body energy to the sword which was imbued with haki "Getsuga Tenshou!" "SWOOOOSH!" a vertical arc-shaped black sword energy with orange outline was projected from the crescent-shaped sword as Renz swung his sword. It travels 100 meters before it dissipated and a explosion occured on the direction where the sword energy faded, the sword energy was filled with compressed energy, so, once it reach its limit the compressed energy will be released causing it to explode. Renz copied this from one of the anime he watched "Bleach" these skill was used by "Ichigo Kurosaki" and the other was "Engetsu" a finishing skill the same as Zoro three sword style technique "Santoryu" but his skill was only one swing with hundreds of slashes.
