The Wrong Dimension (Naruto X HP)

Prologue

Chapter 11: Shinobis, Who are They?

In the most ancient of oldest books in the Restricted Section of the Library was a book detailing the oldest known human race known as...shinobis.

Long, long ago, two different groups of people learned magic. Wizards and witches learned how to direct their inner-magic through wands while ninjas learned signs and jutsus, controlling a inner stream of force known to them as chakra.

Trained from as early as 7 to 8 years of age, they can graduate at any given time with the average graduate age at 12 years of age. Once graduated, they were considered to be adults within their villages and are given missions by their head of government.

They were trained from a early age to kill, to assassinate, to protect, to guard. They didn't bat a eye against blood, nor did they flinch when they were stabbed. It's not like they recommended the idea of killing others, but it was how young ninja candidates were brought up. Given that there was insane S-ranked criminals hiding within the Hidden Continents, generation after generation of children were taught not to fear the idea of blood. Learn to face the pain, but don't seek or embrace it.

After learning the basics (Clones, Transformation, Replacement, Shuriken/Kunai Throwing, Chakra Theory [Hand Seals], Trap Setting), they are then separated into 3-man cells led by a higher- up, where they honed their individual skills on various types of ninjutsu, taijutsu, or genjutsu.

All of the shinobis live on a rather large island located near modern-day Japan, separating into individual nations based on elements. Within each nation dwelled several villages, named by their primary force of defense

5 of them were the most powerful, dominating over the rest of the other shinobi villages: Konohagakure, the 'Village Hidden in the Leaves' (in the Land of Fire); Sunagakure, the 'Village Hidden in Sand' (in the Land of Wind); Iwagakure, the 'Village Hidden by Rocks' (in the Land of Earth); Kumogakure, the 'Village Hidden by Clouds' (in the Land of Lightning); and Kirigakure, the 'Village Hidden by Mist' (in the Land of Water).

Once upon a time, shinobi and kunoichi alike walked the earth with wizards and witches. Healing techniques were shared among nurses and medical ninja, despite the difference in practices and usage. Kages, powerful individual ninjas thought to the leader of a shinobi village, were involved in the political affairs with the Outside, discussing and forming political alliances.

But soon time would drive the two human races apart. Selfish wizards, those who wanted to hang on to their power and fame, would employ shinobi to assassinate others, sometimes their own friend.

The Kages finally snapped, after years and years of endless wars. One war would end only for another to take its place several years later. Truly, the term 'peace' is merely just a word. Peace never existed long in any place.

Erecting a giant shield around their entire island, civilians and ninjas disappeared behind it, to no longer make foriegn contact. Time ran slower inside the shield. Its jutsu formula ever so complicated, it made its own climate in various regions and time slowed down. A decade would trickle by the ninjas as a century raced by the wizards. Civilians forgot there was even land outside of the shield. Memories wiped clean, they lived contentedly without modern technology. 

People, or animals, who managed to find their way in and were affiliated with the Outside's political forces disappear,  were never heard from again. The name, Hidden Continents, came to life. Unplottable, untraceable, none succeeded in contacting the Hidden Shinobi Nations. No wizard since Wizard Year 1650, ever saw a ninja. They only existed inside ancient historical documents. To them, ninjas were a fairy tale. Only a handful still wholeheartedly believes in the existence of ninjas.

politely worded criticism please :)

edit: omggg, i wasnt gonna go off on this but gUYS; i know that konoha, suna, iwa, etc. are basically large (military) villages ("cities" who are we kidding, at this point even in naruto ship. they just need skyscrapers to be 'cities') within a larger nation. but like, the daimyo (even though they're the 'govt.') they do shit nothing; they just sit on their asses and wave their pretty fans while being petty asses. the limited amount of filler episodes i had bothered to watch was pretty much the daimyo sitting around calling for help
