21 5 years

The beautiful trees, the sound of the wind passing through his hair, the chirping sounds of the birds that's what Robin was experiencing right now. He could be seen seated under a large tree, animals all around him looking at him with curious eyes while Cofa just slept on his head. Robin didnt know how long he was seated in that position after all he had no current thoughts at all he just felt at ease in nature right now. After one year of being seated in this position his eyes opened he had changed, he didnt know it yet, but the wind element had made changes not only to his personality but also to his face and body.

He stretched himself and looked around him everywhere were trees birds on the tree branches, and some small animals could be seen running around from time to time again. He felt at peace he had achieved the minor stage in the Wind element and was happy after all he hadnt felt this in his 2 lives combined.

A little black flash could be seen falling towards the ground and then the sound of small growling sounds could be heard.

"Damn Nii-san can you please understand that I was sleeping on your head why the hell would you start to stretch when I'm still there" (Cofa)

Robin looked at the little lion and could see some small changes the little guy had grown a bit bigger about the size of his head he knew soon he wouldn't be able to fit on his head anymore. Also, his pitch black eyes weren't pitch black anymore no they contained traces on white it was something weird, but it made the little lion look even more impressive.

"haha sorry Cofa I forgot you were there after all i don't know how much time I was seated like that, so I wanted to stretch for a bit. But more importantly, what happened to your eyes" Robin asked curiously why he changed like that.

"pff I understand but Nii-san what do you mean my eyes you are the one that hair color changed and my eyes are most likely different because you mastered the Wind element for a bit and we are in a blood contract so I will also have some changes," Cofa said while trying to look smart. But to be honest, the only thing that was to be seen was a little black lion puffing up his chest and putting it forward trying to look impressive. Robin wanted to laugh at this sight, after all, it was like a 4-year-old was trying to act smart in front of his older brother.

"I see but did I change so much" Robin was wondering after all he couldn't feel any changes.

He started to slowly make his way to some water to see his own reflection, and when he looked, he was shocked his hair had changed right now it was entirely white everyone in the leaf wouldn't even believe Kakashi if he said that he was his ADOPTED son so close to Kakashi he looked right now. But his eyes were different there wasn't any white no it was entirely black like the darkness itself were his eyes.

"I see so I will change, but that doesn't matter" (Robin)

Right now it was time for him to start his Water compression he took off his clothes and entered the small river while he was going under water he made a bubble around his head after all he had just reached the minor stage in the wind element so he could make himself breath under water.

Like this 4 years passed Robin didn't know why it took so long but he finally opened his eyes he didn't realize how long had passed, but he didn't care. He felt at peace and calm in the water he stayed in there for an extra hour just to keep feeling like this the current of the water that drifted him to different places some unknown places maybe. But he didn't feel fear like normal humans would when they would possibly see the unknown no, his mind was calm.

He slowly stepped out of the river to see his little brother stand there Cofa had grown and finally started to look like a lion he no longer looked like a cute kitten no he seemed somewhat intimidating.

"So you have also reacher minor stage in Water Nii-san," Cofa said while smiling right now he has changed once again he had stripes of blue mixed into his eyes while Robin himself had blue lines of hair in his white hair that right now reached his back.

"Yes I did Cofa," Robin said while smiling he would be lying if he said he didn't miss this little brother of his.

But he noticed the size of Cofa and decided to tease him for a bit "so my dear little brother you seem to have grown a lot, so I guess the little lion can't sit on my head after all" he was smirking but soon that wasn't the case anymore, after all, he looked at Cofa and right now he could see a cloud of smoke.

And what stepped out of that smoke was Cofa the exact same size when they met each other, and a cute little voice could be heard laughing.

"you weren't the only one that improved my dear Nii-san I can change my size between this one and my original size" Cofa was looking at him like he just won a war.

After looking at each other the boy and the lion started to laugh while they hugged each other.

"I missed you," they said both at the same time the brothers hadn't seen each other in 4 years even if Robin was in meditation he knew he was in it for a long time.

"So what are your plans right now Nii-san" Cofa was wondering this after all the boy that was just about to turn 7 when he left the Hidden leaf their hometown right now was a youth of almost 12 years old, and he knew that deep down he missed his father. Cofa didn't know what a father was, but he could feel the love Robin had for him and deep down Cofa also wanted to get to know the father of Robin better.

"My plan right now is to train for 1 year in this forest and develop some combat techniques, and after that, I will return to the Hidden leave and further than that I don't know yet," Robin said

In his mind he wished to go back, but he knew that even if his combat strength reached early Chunin level, he wasn't truly on that level after all he didn't have any real combat techniques and also didn't have any combat experience just yet. But that would change in the next year when he was planning on fighting Chakra beasts.

And like this Robin's training journey started.

Note: Next chapter will be a training montage of Robin developing his techniques and battles with different chakra beasts it would be a long chapter around 5000 words, so I don't know how fast I will deliver that one most likely a couple of days but enjoy reading this chapter.
