Cos was jumping from tree to tree on the way to Kirigakure, and he had just come out of fire country. It had been 3 days since he left Konoha and he had to admit he loved getting out, although having a place to stay and having everythinng near you was nice and all but adventure was better. Right now he made a living by catching rougue shinobi and you could say he was pretty rich. A single Chunnin level shinobi made him enough money to last one month and he easily cought a chunin once a week so in other words he was really freaking rich. As he made his way to the village nearby he was a bit shocked by what he saw. Around 50 Bandits were robbing the entire village and you could hear many screams of people, he stood there shocked but eventually the last scream died out. While Cos was no Hero of Justice he still believed that this sort of thing was wrong. He shunshined to the village and encountered three of the bandits.
The bandit made a bit of a surprised face due to seeing someone he did not notice before but he shook the feeling off. The bandit began to speak as he reached put to the boy
"Kid Follow me nicely if you wanna live or else you" he never got to finish that sentence as his outstretched arm made a crack. He looked at the boy once more and found rippled pattern eyes staring at him and immense pressure pressing him down to the ground following the immense pain fom his arm.
"You you your one of those shinobi!" He stammered clutching is broken arm
"And what of it..." Cos replied coldly,
"Wait wait, I was forced to do this, I didnt have a choice" he said trying to sound sad as sweat began appearing on his face, he looked at the boy closing his eyes for a second and his mouth turned into a smirk, Either way shinobi or not this was still a kid with his stupid emotions, when he was about to strike the boy while he was ' thinking this' he saw that the boy had vanished and was now standing behind him with a sword in his hand.
"You people are scum, act tough when your big and run when your are small and have no honor you disgust me" at this the bandit had wide eyes but before he could speak any more words he fell down on to the ground forever silenced. How was it that these people were even the same species as him? They were mere insects yet they acted so tough.
He made his way down the road killing every single bandit he saw with an emotionless face, they were mere insects, when he was finished he noticed an old house a bit further away than the other houses and a small noice originating from there, he calmly walked into the small house nearby to witness a young boy of around 8 years old crying, hidden amongst the wooden remains of an old home.
"Hey kid you okay?"
"Who are you? What do you want? I... I dont have anything to give you"
"Dont worry kid Im not one of those bandits, im here to save you, whats your name?"
"Um um my name is Kaito Izami my... my mom told me to hide here... where is she?"
Looking at the kids face Cos didn't know how to help him, he had to know the truth "Im sorry kid, your mom..., she couldn't escape, I didnt find anyone here besides you.
"Your your lying! She cant be, no way!"
"Im sorry kid" Cos couldnt help but look away from the horrific expression on the kid's face
"You know kid, if you so wish I will make an exception for you if you wanna come with me, I could teach you a thing or two, you could strive to help others by getting rid of those kinds of people amd avenge your family?"
Kaito while angry and saddened knew he was fortunate he was that this man was here and was offering him something many would dream of, he after a minute of crying finalluy managed to calm himself down and took the offer.
[5 days later]
Two people wearing jet black armor like clothing were running in the forest, and those two happened to be Cos Kaiser and Kaito Izami.
"Kaito stop, someones following us"
"What should we do Nii san?" Lately Kaito had become very devoted to Cos, almost blindly. Ever since yesterday he had become Cos's little brother.
"Kaito I want you to stay out if this and stay hidden, understand?" Cos said while calmly walking as if nothing was happening
"Hai Nii san" with that he dashed away and just like that Cos also turned around and weaving hand signs seemingly at the speed of light shouted "Fire style: Fire Ball Jutsu!" He unleashed a gigantic fireball which was easily twice the size of normal fire ball jutus. A white entity jumped out of the tree just as the fireball made contact
"Kukukuku now that wasn't nice was it Cos kun" it said as he licked his lips with his long tongue and narrowed eyes
"And following me also isn't the nicest thing either now is it? Orochimaru... What would one of the great sannin want with someone like me?" He said also narrowing his eyes
"So you knew, I wouldnt expect anything less from you, Ive heard a lot about you, they say that you are a genious that made other geniuses feel like trash and I see that that is indeed true, you may even rival Itachi" he said smirking
"Do tell me Orochimaru, how would you know this?"
"I have my ways, tell me Cos kun how would you feel about joining me?"
"And why would I do that?"he asked with a bit of a frown
"I asssure you It would be very beneficial after all we wouldnt want all that potential to be watsed now do we?"
"Im gonna refuse you right here and wnow but I dont assume you plan on letting me walk out of this one would you?"
"Kukuku yes your right, your going to be my vesicle until I get my hands on my original target"
Cos had a deep frown on his face, he wasn't quite sure how he would fare against one of the sannin. Cos quickly took his fighting stance.
"Shadow shuriken jutsu!" Hissed Orochimaru sending tens of shurikens towards Cos
"Earth style: earth wall!" declared Cos as he made a wall and blocked all the shuriken and just as the last shuriken was blocked Cos turned to his right to see Orochimaru on his right and extending his neck and sending his head towards him and ready to mark him, however Cos was fast enough to evade and managed to jump into a nearby tree branch.
"Wind style: Massive air bullets!" Yelled Cos as he spewed massive air projectiles at Orochimaru which was seemingly easily evaded by him. "Intresting Cos kun how do you use all 5 chakra natures? You are making me more and more intrested in you, tell me... what is your seceret?"
Cos made a deep frown, he didn't want to reveal he had the rinnegan yet but he had forgoten that only rinnegan users would be this proficient on all chakra nature jutus, he didnt have much of a choice now, If Orochimaru did some digging around he would find out anyway, better yet kill him now.
"You are too good at this for your own good Orochimaru" Cos said as he revealed his Rinnegan "Lets dance shall we?"
