Blood and Shadow

It was a time long before the first great ninja war, two villages living in the same nation, a nation unheard of at this time, these two villages were the only known military villages in the nation of 'darkness'.

One of these villages was known as 'occulta sanguis vicus' also known as 'village hidden in blood', a strong legendary 'tribe' or culture lived in this village, only known as 'sanguis users' which means 'Blood users', this legendary culture were known only for their cruelty and need for blood, through generations of blood and gore they were able to unlock a secret weapon, whether it was through mutation or luck or corruption of the soul, they had unlocked a weapon that was strong enough for them to live for centuries on without being challenged, this was known as 'Sanguigan' it was only a known doujutsu kekkai genkai in the nation of darkness, but it's abilities rivaled that of the sharingan or byakugan, maybe not the rinnegan but it was very powerful, this doujutsu allowed the user to use many different techniques.

The Sanguigan's first use upon activation is easily noticed, the user being able to see the blood literally run through any human around them, they are able to switch their vision like a muscle whenever they wish to see the blood coursing through someone's veins, this allows them to see every muscle, every tendon, every chakra point and every white blood cell in the body, this can be useful in many ways, however this power was used for violence rather than using it to the best of its abilities, but what can you expect from a culture that is completely based on blood, gore, hate and death.

Depending on the rate of one's strength or ability, Sanguigan can develop further to a stronger state, known as 'Operativa Sanguigan' this is known as the second stage of Sanguigan which allows the user to use what is known as 'blood jutsu' or 'blood style' This allows the user to then use their Sanguigan to control blood itself, this meaning that they can use jutsu to control the blood inside someone itself or maybe even their own blood, however it takes a very large amount of chakra to control blood itself, many have tried and failed to use the Sanguigan to rip blood out of their opponent in order to kill them instantly, and have failed to do so due to the strain of using so much chakra, even attempting it can reduce you to zero chakra, worst case scenario, you die.

Many however have created very useful jutsu and taught their jutsu to one another in order to increase their power, many blood jutsu were created, though some jutsu were unable to be finished simply because they did not have enough chakra to finish creating it, even so there are many uses for blood jutsu, following further development the Sanguigan can then develop into 'Kaleido Sanguigan' Which allows the user to enter the third stage of Sanguigan, this is very rare though and it is said to get to this stage some very horrific unimaginable things must be done not to mention how difficult it would be to even unlock this stage, however it has been done and the results are immense, specifically a jutsu known as 'Sanguis mens rapidus' a very strong blood style jutsu that has killed many opponents in battle, though there are no records left of it or what it exactly does..

"Anyway children enough of that for now, it's rather late and I think its time you went to bed." Said the old sage named Sapien.

He had a gruff grey beard and was rather frail and quite short, sporting a blood red tunic with a small hat which had a weird symbol upon it, the symbol for blood, the symbol was an M darkly outlined in red, it had a kunai going through the middle downward with too spikes either side of the middle of it, the M also had dark red spikes on the outside of it, he also wore wooden sandals and his tunic had a black cotton lining and was rather dirty with stains of a darker blood red upon it, supposedly real blood, the symbol also resigned on the back of his tunic, the lighting of the tent shone brightly on his tunic, giving off a rather strange but almost invisible red glow, the tent was old but quite large, 10 ft high and 15 ft wide, sporting only an old creaky wooden table and a camping sleep roll, there were many candles around a strange image with a book in front of it.

"But I was learning so much!" Stated a young girl named Suki

"Yeah!" Chorused a large group of children

"Well i'm sorry children but its time to go to bed, i'll resume my tale tomorrow, I got sidetracked after mentioning the Sanguigan I apologize.."

"Ohhhh!" chorused the group of children as they departed to their own separate tents.

The old sage smiled as they left and turned around to his small wooden table and decided to continue writing his book, when he sensed someone still remaining in his tent.. he turned around and greeted two young girls, they were both eighteen, they had only turned eighteen a few weeks ago, on the day of 'that' incident, he smiled genuinely towards them.

"Hello girls how can I help you?" The old sage asked turning around

Suki and her twin sister Kaiyo smiled back and sat down..

Suki was 5 '8' and had dark blonde hair and hazel eyes, she wore a short red skirt and tank top with the same blood symbol as the old sage Sapien, she also wore red wristbands on both arms and red elbow pads with a gold outlining around them, they were a rather handy defense along with the strong knee high red leather boots she wore, just above her boots she wore a bandage on her right leg and a red leather holder for a few kunai, although she didn't have them equipped at this time, on the back of her red tank top was the blood symbol once again, wrapped around her neck was a black cloth with a metal plate in the middle with the blood symbol upon it called a forehead protector, many ninjas wore it on their foreheads, whereas many others didn't.

Kaiyo was 5'7' however and though only an inch shorter then her sister, she still felt a bit uneasy when comparing herself, as sisters do, she had bright blonde hair with slight red streaks, she also wore red wristbands and elbow pads although her pads had a black outlining rather than a gold, she wore a red shirt and a black and red jacket with the blood symbol on the back, her forehead protector however was wrapped around her forehead, she too had hazel eyes, though hers were closer to black then hazel, she also wore red shorts and a satchel on her waist to hold her ninja tools, she wore knee high black boots with a red outlining and had bandages around her left thigh.

"Please tell us more, we want to learn.. we want to be able to defend ourselves.."

"Ah yes, Fine I shall continue, the story was getting a bit too dark for the others im afraid, we may be of the Sangui culture however I do not wish to follow in the footsteps of my predecessors and corrupt the minds of our young, unfortunately you girls have been alive long enough to become chunin and fight in our terrible war against 'Them'..."

"That's why we want to learn more, we want to protect you and the others!" Exclaimed Kaiyo

The old sage chuckled and replied slowly

"Very well.. I will tell you the tale"

'Our culture was unchallenged for centuries to come, until a large group of bandits took over and destroyed many villages in the nation of darkness, thought to be a band of bandits that were for some reason laying low for centuries, it turned out they were an ancient tribe.. their powers long forgotten until one day, a boy who is now the leader of the hidden shadow village 'occulta umbra vicus' unlocked his true potential, and then trained himself on his own, he mastered his abilities as best as he could before he showed them to his band, they all started to learn and grow potential, until they all unlocked their abilities and the now well known to us band of bandits, founded their village after destroying many of our own, we should of dealt with them sooner, but we weren't ready for such a strong power to befall us, since before the first great ninja war our two villages have waged war on one another, rivals till the bitter end, even our doujutsu rivaled theirs, yes we were equal strength-ed, we lost battles and won them, as did they, but that's all over now.. i'm sorry girls, i can't continue this tale, it saddens me too greatly..'

"It's okay, we know about the rest, we experienced it somewhat.. I wish i could of seen the monster that destroyed our village! And caused us all to be outcasts and orphans!" Exclaimed Suki

"I wish for vengeance on the 'umbrage' for all of their crimes, I will have my vengeance as soon as I unlock my sanguigan! Trust me!" Kaiyo stated proudly.

"And I hope you do, until then continue your training, master your natures and soon your sanguigan will unlock, but don't dwell on the sanguigan too much, it will unlock in its own time, forcing it will do you no good, only harm.. now go to bed and continue your training.. I will speak to you both in the morning."

"Good night senpai" Said both the girls before they left the tent and went to sleep.

The old sage smiled as he continued his book, 'I hope this helps them, they are our cultures last hope of survival..'
