The first day after Nero and Deva had worked out their initial training regime. Deva left Nero back at their home to his reading and went straight to the beach.

Deva wanted to use the early mornings where it still had not warmed up as much to do her endurance exercises.

The Shadow Scroll had tips and advice for training a young aspiring shinobi in their early years so as to not negatively affect their growth.

It was recommended that endurance training to be used early on to build up the youth's stamina so that they may spend a lot longer training in other things in the future.

So following the recommendations of wise and old veterans, Deva ran as long as her tiny body could.

After 15 minutes she had to stop and rest for a few minutes in exhaustion. Running while the sand adds resistance makes it so much difficult, but seeing how it would not hinder her growth she proceeds anyways.

After a few hours of torturous running on the beach. Deva rests beneath a tree in the shade and goes over another subject to train in. This time the subject of handseals are brought up.

So until lunch time she would practice each seal individually before doing comboes. Deva would delegate a portion of her time every day for a year until she is able to perform flawlessly any combination of hand seals in record time.

To her it is a necessary skill to master, for the quicker she can launch a jutsu, the quicker she can kill or escape an enemy.

At night Deva would read one of the chakra control scrolls and start with the basic Leaf Exercises. By using her chakra, Deva would attempt to stick a leaf to her forehead.

Despite how simple it may seem, Deva would only succeed in doing it once before bedtime.

...

It did not take Deva long to master the leaf exercise, but she would still spend time doing it to build up her reserves, while simultaneously adding more leaves and at different parts of her body.

If she can release chakra out of her body simultaneously from different parts, then she would never have problems in the future with certain techniques. The Hyuga Rotation technique comes to mind.

After a year of relentless physical conditioning, and rejuvenating cuddling with Nero at bedtime, Deva has come to feel ready to take her training to the next level.

Deva started practicing some basic academy level martial arts, or taijutsu as it is called in the original works. She would follow the katas to the point using a similar training hologram system that Nero used when he started practical lessons.

Just like Nero's training instructors, Deva's would go blue with success, red with failure, and gold with mastery.

So Deva would stubbornly practice over and over again for days until she saw that beautiful gold signalling her mastery before moving on to the next kata.

After perfecting each kata individually Deva would begin the process of combining them perfectly. She went slow at first but gradually getting faster as she had gotten used to one speed.

Soon enough her speed when practicing her katas have gone fast enough that it would impress the Green Beast himself.

Deva was a natural born ninja yo!

...

It was as Nero had suspected.

When the Apes have witnessed Deva's training and martial arts, they too had joined in on the fun.

You know what they say, "Monkey see, monkey do."

When Nero had come to the beach one day to relax after a long study session and saw the apes following Deva in her training regime. He could only sigh and say...

"Jesus Christ," Nero sighs, "are these fucking apes gonna turn into saiyans after this?"

Nero proceeds to return home mumbling something about being too old for this shit.

...

==Deva's Stealth Training==

The sky is blanketed in dark clouds. Despite being midday, it is very dark. The wind blows heavily and the occasional drops of water can be seen dropping. The sky is threatening to burst into a storm at a moment's notice.

Beneath a tree, munching on some berries, is Nero. Relaxing after practicing his rune carving. His outfit is a little tattered, a side effect of his failure in his latest session. Runes are not safe, but they are beneficial once mastered.

A small figure slowly creeps closer to the seemingly "unsuspecting" Nero, sticking to the shadows and his blind spot.

Closer and closer the predator moves towards it's prey, lowering itself into position. Ready to pounce when the time is right.

Nero sighs and smiles while saying, "Nice try Deva, but not good enough." He then proceeds to flick a berry back and splatters it over her forehead.

"DRATS!"

Deva comes stalking out of the shadows sulking while rubbing the berry juices off her forehead.

"Aww man!" I thought I had you!" She glares at Nero and accuses, "You cheated didn't you? Fess up!"

Nero chuckles and said, "My magic is not any less cheating than your shinobi chakra. I am just a bad target for this training."

She huffs and sits down in annoyance with her arms crossed. Looking at Nero, Deva said, "I don't buy it, cheater! I gots my eyes on you bub, all 3 of em!"

"Hahaha! Why are trying to use me as your first stalking target?" Nero asks.

"Lets see here..." She briefly before answering, "Boar Lord is hard mode, Snakey is very hard mode, the monkeys have trained with me so that makes them elite mode, White Kitty is nightmare mode, and even a single raptor is DMD mode."

"Well there is your problem! Your trying to defeat the bosses before dealing with the mobs. Try the weaker animals then progress upwards. Then beat the boss by being overleveled." Nero says, suggesting a progression system.

Deva nods her head before sighing.

"I guess it was too much to expect for me to be able to pull a Dark Souls level 1 win." Deva says in defeat causing Nero to chuckle.

From that moment on Deva started to progressively improve her stealth skills, and boy did it take her a while to get the hang of it. Deva has, in the beginning at the very least, had the stealth potential of a bull in a china shop.

Even the animals with the worst possible hearing could hear her coming.

Through stubborn persistence did she finally improve her stealth skills. In the later years of their training was she able to stroll through raptor territory unnoticed.

But much to her annoyance, Deva was still unable to sneak up on that cheating bastard Nero and, for some reason, her pet raptor Blue too.

The little feathery fellow joined in on her training, eventually becoming able to harness and manipulate chakra, and surpassed Deva in becoming the sneakiest creature in Avalon.

Deva ended up depressed for a while. Her nin-raptor was sneakier than her, most of the apes have become more proficient than her at martial arts, and she can still not sneak up on her man!

Deva was not gonna take it sitting down! Her training went up in intensity. She will dominate this island and laugh on as everything bows down to her, admiring her supreme might!

Of course in the future she would still be disappointed to know that Nero would have her beat in everything but brute force.

Eventually she would start her training in other ninja arts. Ninjutsu, swordsmanship, sealing arts, illusions.

Eventually she was able to awaken both of her eyes. The Byakugan and the one single Sharingan on her forehead. So she started adding those to her training as well.

Her goal is to remove the blind spot of her all seeing eyes, while also reaching Eternal with her sharingan. Hopeful that she can unlock the Rinnegan and maybe at one point the Rinne-Sharingan.

But those hopes will be for the future.

By the time they reach 17 years of age, Deva had already become talented in all of the Nature Releases, main and sub. True to her goal, the eyes have reached her desired levels.

Eternal for the Mangekyo Sharingan and a perfectly 360° range of vision for her Byakugan. The blind spot has officially been removed!

And just like that, their years of training in seclusion have come to an end. Two ridiculously overpowered teenagers will soon step into the wide world to see where they ended up.
