Chapter 5 - To Fight An Assassin

Kai was busy waiting for Chusuke to get done with class whenever three bigger boys came up to him.

" We heard you put a hand on Ryuuto, That's a big no-no," said The biggest boy he was around 5'6 and was built kinda stocky,

" He laid his hands on me first, and I gave him a warning," said Kai.

" That may be true, but that's not the way we see it," the second boy who was on the heftier side of the group,

" Is that so?" Kai asked the rotund boy.

" There's three of us and one of you," said the third one a lanky teen who had the appearance similar to giant baba.

" Now you may not understand the situation here,' said Kai, "The three of you are ganging up on one person, now the way you see it they'll take your word because there's three of you, but the way the adults see it is that when three boys gang up on one boy it's an act of bullying," Kai replied explaining the situation since he had lived to his 20's on his previous life he had the knowledge that comes with adulthood.

" Heh, Not when your a stranger Nin-ja," he said syllabling the last words.

Kai sighed he assumed his Kage-ken fighting stance which was a southpaw Philly shell stance.

The three boys were about to attack him whenever a gruff voice spoke up.

" What's going on here," asked A man dressed in a ceremonial Kimono.

" Nothing sir," said The leader of the boys.

Kai felt something off about this man's chakra as if he were using a transformation.

Suddenly Kai got a warning from his system.

[ Be careful of the lizard men] said the system.

This earned an eye twitch from Kai, He remembered that chapter knowing damn well that the warning referred to a group of men who took advantage of weaker people leaving them for dead and having them killed.

Kai noticed the man leave he secretly followed him using stealth as the man suddenly vanished via a Shunshin-No-Jutsu.

' Of Course He's A Shinobi,' Kai thought internally.

Kai sensed the man's presence a mile away by now.

" Typical must be a Chūnin and he must be using the Kage-tobu-no-jutsu/ art of shadow jumping, and with my current task right now I can't give chase, fortunately I can complete my daily mission during the school's Phys-ed period," said Kai.

And right as Kai said that the group gathered to learn Phys-ed.

Kai was in the Nobleman's academy training ground doing his daily mission of 100 hundred pushups 100 sit-ups, 100 squats and a ten Kilometer run.

Naturally everyone who was attending was surprised to see how Kai was used to such an exercise.

Chusuke was also able to keep up with Kai up until the 4th kilometer.

" How can he run Ten kilometers and not break a sweat?" Asked the boys.

" Well he's a Shinobi so yeah," said Chusuke.

The next half of Phys-ed involved training in Taijutsu and Kenjutsu.

Kai noticed that Chusuke had the manners of one who was once learning but then lacking in proper training.

" Hey Chusuke come here?" He said.

Chusuke came over.

" Tell me when did they quite giving you lessons?" Asked Kai.

" About two months ago they said I no longer needed them, but I know they lied and when I told my father they showed him fake records," said Chusuke.

" ...then how about we make those records true," Kai offered.

the next day Chusuke was using more proper footwork and fighting applications this was due to Kai setting up Floor decals and targets for Chusuke to practice on and to Kai drilling him in kata from His knowledge of Shotokan and kickboxing from his previous life.

His sword fighting form improved as well this was due to Kai teaching him proper sword forms from Kendo and fencing having him learn a mix of both to teach him to wield a two handed and one handed sword Kai also taught him a sword style based on the one used by obi-wan Kenobi called soresu however I expanded on it by adding counter cuts and reversals essentially giving it offensive counter-attacks.

As the day went by I reported to Sensei Ayeka about the fact that I've noticed that some strange things one the teachers stopped teaching Chusuke self defense about two months ago that would be enough time to make his training and cultivation lag behind his fellow students who were at least the level of a mid-level Genin, Second: The teacher had lied to Chusuke's father not only that they had lied to the Daimyo's which is a crime punishable by death, and finally: there had been sightings of a man in a hood appearing at the school by several students.

" I see, that is quite troublesome, very well then Kai if you encounter any trouble I shall give you permission to take action and defend yourself," said Ayeka.

" Hai Sensei, good to know," I said my old habits from my karate class coming back.

During free period at the academy I decided to go for a walk with Chusuke as we stepped closer to the woods and told Chusuke I needed to pee which was a lie so I slipped into the bushes and summoned a shadow clone before using Shunshin-No-Jutsu to hide in a tree at that moment the hooded figure appeared and attacked Chusuke fortunately at that moment Burai came out and parried the man's daggers.

I leaped down from the tree and delivered a corkscrew roundhouse kick to the man's head " looks there's trouble in paradise baby!" Shouted kai in his best Jamaican accent while drawing my knives landing on the ground he smirked " party time!" Kai said and attacked the Assassin who parried my Kunai and my Dagger as I cut his knives using a mixture of movements from Wing Chun, Penkak Silat and Escrima.

The assassin cursed especially since Burai was cornering him as he tried to retreat.

He smirked and used a Shunshin-No-Jutsu to vanish before reappearing behind Kai stabbing him through the back.

" Kai-Kun!" Shouted Chusuke,

However, Kai suddenly vanished in a puff of smoke as a log with a stab wound appeared with the man's knife buried in it and Kai reappeared behind the man burying the poisonous blade of Kasaka's Venom Fang into the man's heart from the center of his back.

As Kai leaned into the man's ear, " word of advice lizard, don't mess around with the wolverine," said Kai and he toar the man's heart out from behind with a pull of his Dagger as the assassin died.

Konami removed the vital organ from his blade and then he wiped the blood from the fang before konami holstered his dagger.

Konami walked over to the surprised boy.

" Konami-kun, wha wha-what the hell is that thing?!" Said Chusuke pointing to Burai.

" His name is Burai, and he's a shadow created from my personal kekkie Genkai that is unique to me," Kai explained, " he's also the spirit of my ancestor," he added.

" Do your Sensei or teammates know about this?" Asked Chusuke before Kai put a finger to up to his mouth and whispered.

" This is our little secret okay Chusuké you and I will be the only ones who know about this bloodline for now," said Kai.

" How does it work?" Asked Chusuke.

Kai walked over to the man and held up his hand, " Arise!" He said as the assassins Shadow was drawn from the Assassins body and the boy backed up.

" Don't worry he won't be able to hurt you," Kai informed Chusuke, " because he's under my rule, that means he is bound to follow my orders, unless he deems them compromising or Beyond normal ethics," he explained.

Then took the head and heart of the Assassin and took them to the Daimyo Palace.

" What the heck is even that," said the warlord.

" It's the heart and head of the assassin who tried to kill your son," said Kai.

" You couldn't have possibly defeated it on your own, you're just a Genin," said the warlord.

" No-no-no-no see that's where you are mistaken about the squad that I'm on," said Kai, " see unlike normal squads miss Ayeka's is special because it's a squad specifically meant for the Genins who have more battle experience and abilities than any other Genins in the academy and out of all the 11 teams; team 11's purpose is to act specifically as an execution squad meaning that it is our job to deal with those who would try and harm or kill important officials, or—their families, such as yourself and your son, also last time I checked you trusted your son's teacher instead of investigating their lies and your wife has lost her cat due to her smothering it till it's scared spitless and right now I believe you just hired team 7 to catch it for about the 21st time in the past 2 years," Kai explained using his knowledge of the Anime as a bargaining chip to point out the Daimyo's folly.

The Daimyo was silent because 1 Kai was right, 2 Kai Adressed something the Daimyo had never had the ability to address since if he showed favor to his son he wouldve been seen as a nepotic and three he couldn't fathom how Kai knew about the cat.

" I see your point, but how did you know about the cat?" Asked The Daimyo.

" 3 reasons: one I have a sort of latent precognitive ability, two: I Knew that cat had probably ran away multiple times due to how that woman keeps it caged which you don't do to cats, and how she smothers it, and three: My best friend is on team 7 and he lets me know about his E-rank missions since they're not top secret and I left a shadow clone at the village to keep up with Taijutsu training and to check in on my old man every once in a while," said Kai.

The Daimyo was surprised as the first was a rare ability two a kid had noticed things nobody else did and three this welp could make shadow clones as in the thing that was banned due to major deaths in Genin classes due to mistakes made by Senseis and was the reason Chūnin were only allowed to train kids, and this kid knew it.

" Erm Kai-Kun was it, how many clones can your creat as of Now?" Asked the Warlord.

" Hmm at the most I can probably create about 600, the friend I mentioned can creat up to about 2000 if he's using the multiple variant and if he's using the normal variant about 900 at most," said Kai.

" Hoova, you kids are insane, just what Clan is your friend from," he asked.

" My friend is from the Uzumaki clan, he is also the heir of Minato Namikaze although...that is a secret that is to be guarded with your life and if it slips from this room there will be the need of crowning a new warlord," I said with a smile that hid a silent fury with the strength of a raging typhoon.

The Daimyo had nervous smile on his face as he had a pale sweat, " Oh...I see," said the Daimyo.

" Don't worry sir by this time tomorrow all those who were the culprits of this crime will be dealt with," I said.

Later that night I slipped into the hidden base of those who came up with this ploy as the shadow of the assassin I had named Morpheus lead me to, I slipped into the base and with help of both Morpheus and Burai I began my slaughter.

The system repeated as I slayed every Chūnin level and Jōnin level Bandit and Assassin, Not only did I gain levels but also my two shadows.

From there I used shadow Extraction and Shadow Preservation to add them to my armies fortunately for me each of the members were Either Nukenin or soldiers who had some degree of chakra usage and a bounty even though they only had the standard fire jutsu and Fundamental academy Jutsu fortunately with the way my shaodws worked they had a had access to most of my Ninjutsu techniques except for my God hand and Burning blow and My

After the battle ended I added my skill points to my status before I noticed a rune stone on the ground.

I picked it up and I once I did the female voice of the system spoke up.

" Impressive, so after that I gained 6 levels and obtained a 30 boost in my stats due to my use of shadow clones," Kai said in surprise.

Kai returned and reported to Ayeka that he had disposed of the threat much to her surprise after a quick lecture about team work, Ayeka informed the Daimyo.

I then turned in the heads of the ninja and quickly obtained the bounty per ninja which was about sixty thousand per head resulting in over six million Ryō, as well as The payment to the village was 50,000 Ryō plus 10,000 Ryō to the village however Kai was rewarded and extra 20,000 in courtesy of Chusukè.

Kai smirked he returned home to Konoha right as Naruto and his team were heading for the land of waves.

" You guys better, come back stronger and all in one piece now, Ya Hear," said Kai.

" Of course we will just who the hell do you think we are," said Naruto with a Foxy Grin.

Kai returned to his house.

" Hey pops I'm home," He called out as he entered his house.

" Kai-Kun, your back tell me, did you have fun with your special assignment," said Iga.

" Yeah it was cool I made a couple friends," said Kai.

" And you even got to kill 100 rogues," said Iga with a happy tone that held the secret message of let's have a little chat aka your in trouble and I'm disappointed.

" Eh, hehe, Oh shit," said Kai.

The next few minutes the village heard the cries of a young man getting his ass tore up with a leather strap.

[ It was at this moment Kai Knew...He Fucked Up,] said the system.

A few weeks later Ayeka called us in.

" It appears that we have been given a new mission, it is a C-rank assignment as we are to assist Team seven in their duty at the land of waves, apparently an S Rank Nukenin Has been hired to deal with their squad, and we are to help assist them in dealing with this threat," Ayeka explained.

' this'll be good, I can gain some levels and probably get myself, Zabuza and Haku Yukki, as shadows, the later of course I'll try to keep from dying as much as I can, maybe Himiko can help defend against Haku's ice needles with her Gentle fist using a technique similar to the water stream encampment,' thought Kai.

" Hey, Himiko, do you know any Taijutsu techniques that can defend attacks from a range of 360 degrees," asked Kai.

" Actually I developed one 3 days ago; I call it The Taikyoku-shou: Gekiha-Shisui," she said.

" Universal Extreme Palm: Fierce Wave still water Huh," I said in surprise.

" Indeed, I Even taught my cousin Hinata how to do it," said Himiko.

" Sweet," Kai said and then Yoshiko and Ayeka called out to us asking to meet up with them near the gate of the village.

Kai and Himiko arrived at the gate where Ayeka and Yoshiko were waiting for us.

" So what were the two of you talking about?" Asked Yoshiko.

" Just Taijutsu and our different styles," said Himiko As Icy as ever.

The four of us then quickly made our way to the border of the country if you are surprised, don't be the only reason it took team seven so long was because they had to escort that old sot along the way.

We quickly arrived at the ferry where we would be taken to the land of waves within a day however Ayeka used a secret Jutsu that allowed us to travel three times as fast which was the same technique she used to create a barrier field around herself.

" Uchuu-ton: Gosei-kekkai Suisei/ Cosmic Release: Earthstar Barrier Comet," Ayeka said surprising us before launching us across the sea like some sort of motorboat powered on Unlimited fuel and Nitrous Oxide.

When we stopped Himiko got Vertigo, Yoshiko was shaking, Kai stepped out of the boat smiling. " Sweet Service let's do that again Sensei," I said causing the two to look at me with lifeless eyes even for a Hyuga whose eyes are blank unless with their Byakugan active with the look in their eyes saying kill me if that ever happens.

As we walked we passed the swamp and got into the village to meet up with Naruto and crew.

" Hey, Kai-Kun You're here guess what we faced a member of the legendary Swordsman of the mist and Sasuke and I fought against him while kakashi got trapped and I freed kakashi by using my water streaming rock smashing fist to launch his clones sword at him," said Naruto.

" Sounds like you had a good week, as for me, I got some good training in and I Even got to go joy-riding," Kai told the ever rambunctious blonde.

" Kakashi Sensei, did we have to have back up we could handle this ourselves," asked Sasukè.

" Now Sasukè, The Hokage sent these four to help train you three to get stronger," Kakashi explained.

" Hn," Sasukè grunted dismissively.

Kai and the others began training.

Sasuke had managed to awaken his Sharingan.

Naruto and Yoshiko decided to train in order to get better acquainted with each other, Sakura decided to train with Yoshiko in order to improve her Taijutsu skills which impressed everyone with her effort to grow stronger, and that just left Sasuke and I.

" Listen, I don't need your help training," said Sasukè but before he knew it I was in front of him as I activated my blood lust skill.

" Listen here you little shit." Kai said With immense killing intent, " I don't care how Elite your clan is, last time I checked they're not around anymore, and when it comes to their status, nobody gave a flying fuck about their lineage, last time I checked you were a fresh out of the academy Genin with no achievements to his name, and You are relying on your family's status to make yourself top dog," Kai shouted before leering him dead in the eye as his eyes glowed with a cool blue light, " So stop acting like a spoiled brat and Grow Up," He said putting emphasis on the last two words

Sasuke felt his legs give out he had felt fear from Zabuza but even then He never felt this level of Killer Intent from Anyone Until now.

" Now you are going to stop acting like hot shit and train with me," said Kai, " Or— I'll turn you into an Eunuch, Do you understand me," while having a smile that said just try and find out.

Sasuke managed to get a little strength back but he knew he had to comply or the Uchiha clan may just end with him on this particular mission.

For the next for hours Sasuke was training his butt off learning what he could from Kai despite what he expected Kai actually was pretty chill when it came to teaching him in fact he was even more thorough with explaining techniques to Sasuke than Kakashi was, Sasuke also learned how to use Denjin-Reiki to give him more speed and a better chance at survival even though it wasn't at the same level as Naruto and Kai's technique.

A few days into it Kakashi and Ayeka decided to teach the kids ond of the more essential techniques for ninja to use.

" So what is it we are learning?" Asked Naruto excitedly.

" It's a fundamental skill every ninja needs to know, it's tree walking, The technique itself is a form of Tree walking," said Ayeka.

Himiko being a Hyuga and thus having the best talent in directing chakra was the one to demonstrate the technique.

" The trick is to circulate your chakra into the soles of your feet as you step up the tree you direct that chakra into the tree and walk up it," said Himiko in a cold yet friendly manner.

I was able to do it thanks to my high level of chakra control despite it being in the 50's that was just a rough estimate in fact the base level of a stat is actually a percentage of the actual amount so while my chakra control stat level is 57 my actual chakra control ability is somewhere around 760, just like my chakra capacity being around 67 but being somewhere around 970 the stat is actually 30+ due to how the leveling system works and as for my personal level I'm at least at level 46

Naruto had managed to pick it up surprisingly quick while Sasuke also managed to pick it up as well.

[ You have learned a new skill: Tree walking Jutsu, user can now walk up tree's passively as a way to travel faster,] said the female voice of the system.

' Technically it's more of a drill than an actual technique not that I'm complaining since it gives me more ways to increase my chakra Capacity and Control, hell even in the original Japanese manga it's name is called Tree Climbing Practice,' Kai thought to himself.

As he did a free fall from the tree before flipping into a quadruple somersault and landed on his feet.

" That was fun," Kai said with a smirk.

Naruto did it as well although he wound up landing in an awkward position where he fell into a split.

" Yipe!" He yelped as he landed in a split.

We all couldn't withhold our laughter and soon everyone even Sasuke couldn't hold it in.

A few days later I was relaxing in the marsh with Naruto when suddenly a girl stood before the two of us.

" The two of you seem relaxed," said the Giry.

" Well our Senseis told us to take it easy every once and a while," said Naruto.

" Just don't go getting yourself sick," said the giy.

" Sure sis," said Naruto.

" Well I just came to gather herbs," said the Goy.

" Sure thing sis," said Naruto.

She turned around, " by the way I'm a boy," said the boy.

" What the Hell, He's prettier than Sakura, I've seen some crazy shit in my day but this one takes the cake," said Naruto in utter shock.

" Talk about androgynous," Kai said with a strained voice.

" I'll see you two around," he said and he walked off.

' I need strong shadows, but I still want to try and prevent his death as much as possible,' Kai thought to himself.

Kai and Naruto returned home and prepared for the battle at the end of the week.

To be continued.

( Authors notes)

I wanted to end it there because I was pushing my word cap.

Anyway I wanted to ask you guys what you think if I included girls from the movies and videogames into Kai's Harem.

The list I've made are the following.

Himiko Hyuga.

Yoshiko Senju-Misaki.

Kin: she feels remorse for trying to start the war after becoming attracted to Kai and discovers that the ploy is to kill the Hokage she decides to inform them and joins Kai's harem.

Koyuki Kazahana ( the spring Daimyo from Naruto movie 1)

shion ( priestess of the land of demons,)

Sāra ( princess of kingdom of Rōran/ her descendant of the same name who is also her reincarnation) this one is a bit complex so let me break it down in the past Kai meets Sāra due to a time slip where he's sent back over 800 years to the kingdom of Rōran after helping save it from the evil that would destroy it he returned to the current time where Sāra's descendant of the same name who is also her reincarnation wound up falling for Kai and she eventually becomes Kai's lover.

That's all I have for now

Anyways that's it for this chapter; see you next time.

Ciao.
