The Experiment
Few weeks after the joint force investigation between both of the villages had begun, two groups of citizens and shinobi alike found themselves trapped in some-sort of a cave, separated from eachother. The shinobi were group A, as the letter was painted on their torso and the citzens were group B. To their own surprise they found out that they were all from different villages, some appeared to be from the Sand and some from the Leaf, pit together with eachother. Panic broke loose among the group B, while group A were trying to analyze the situation with a calm attitude, just like they were taught to. Upon closer inspection they noticed that they all had strange dual-syringe markings around their necks, they also felt a great disturbance in their chakra but they couldn’t feel or sense anything outside the cave. After some time both of the groups stumbled upon a letter, left for each of them.
’’Good morning, I want to play a game. You of the shinobi world were taught how to handle situations like these. You were taught how to think with a clear mind, to fight in battle and survive in outmost disgusting ways. A test for your capabilities. The shinobi you see with you are from different villages, that is correct. You are all connected to eachother as you have killed family members, loved ones, team-mates of one another. I am sure that if you look closely and remind yourselves of those specific situations, you will recognize eachother. Your test is to look past the differences, to forgive one another and to survive this game of mine by escaping from the cave. Time is not on your side, good luck. Y.’’
After reading that letter out loud there was a moment of silence, a shinobi from the hidden leaf briefly glanced at a shinobi from the sand and recognized him as being the one who killed his son in battle. The rest of them also began recognizing one another from certain times in the past. Shortly after, the group divided themselves between the villages and engaged in combat with one another.
’’Good evening, I want to play a game. You are dear citizens of the land of Fire and Wind. Personally I have nothing against you but during your lives you were all too afraid of something, to achieve what you truly wanted. You didnt use the gift of life, rather disregarded it because of your fears. I promise you this, if you manage to complete this test, to survive, to surpass your fears. You will be granted a power of your desire, to overcome your weaknesses and fulfill your dreams. Time is not on your side as your obstacles grow stronger by every minute. To pass this test, you must win the game. Escape from this cave and remove your obstacles that you find on your way out. Good luck. Y. ’’
The citizens looked at eachother, in a slight disgust. Realising they were from different villages that were at war not so long ago but unlike the shinobi they were capable of looking past of what happened before and to work together. They gathered up and formed one large, united group, and proceed forward. As they passed the first phase, they stumbled upon several weapons attatched to a wall, swords, spears whatever you could find useful in battle. The number of tools left for them was the exact number of the people, and after being armed they proceed to phase two. They ended up in what appeared to be a larger area, with more light in the room coming from several lanterns across the area. In that area they came across several mutated beasts. Those who lacked the courage to fight died but those who gathered all their inner strength and courage passed through and eventually escaped from the cave. Moments after the last survivor managed to escape from the claws of a mutated beast not far from the exit, a certain figure appeared at the entrance wearing a white hooded robe.
Glancing at the beast charging at him, followed by few others, the man said ’’Game over.’’ before sealing the cave completely and placing a simple barrier jutsu upon it. Turning around and revealing parts of his face to the survivors by removing the hood from his head, a man wearing a white hooded robe and a red metallic face-mask, with long white hair and crimson red eyes appeared before them.

’’You have all passed the test. I congratulate you. You were promised power and you have received it. The markings on your necks are fruits of my experiments that I have conducted over the past years. I constructed this cave behind me specifically for this. Inside of this cave was a great source of nature energy, reacting to a certain liquid that was injected in your bodies, one that required to be close to the source to activate and an emotional outbreak, such as surge of adrenaline for example. But had you not worked together and remained in that cave for longer, you would have become the bi-products of experimentation, just like those you fought on your way out. While those failures are strong, the power you possess now is far beyond that, and with time you will control it. Good luck, dear citizens I am sure there is a greater destiny awaiting you. Experiment Sucessfull.’’
Until we meet again
Sixty years has passed. After the experiment was considered a success, Yukimura had halted all of his projects and dissapeared without a trace. The survivors returned to their villages with powers beyond their imaginations. The Medical Ninjas studied them and their powers for years to come, later on developing a pseudo-outcome of what Yukimura had achieved, that was named ’’The Cursed Seal’’. They used the power of the Cursed Seal to finally overcome the war against the Hellspitter, who was so close to wipe them all out.
The failed experiments, later known as the ’’Cursed Hosts’’ eventually broke through the barrier set on their tomb and terrorized the smaller villages nearby, spreading their disease across the lands until they were initially put down and later on controlled by the Konoha and Sunagakure.
The scientist who fell under the description of those who survived was never seen after, his documented experiments and other works were discovered later on and studied upon. While he was feared by almost everyone for what he had done in the past, some saw brilliance in his experiments and studies. The knowledge possesed from the data he left behind skyrocketed the advancement in medicine, technology and science all together. In the end nobody knew who he was, the only thing that was known was his visual description from the survivors of his experiment and the initals he left behind on his works, ’’Y.’’
Two centuries passed. The ninja world had become far different from what it was before but the problems between the villages eventually remained the same. The power of the cursed seal was wide-spread across the ninja world. Weaponized and now used by the authorities to gain advantage over one another.
On a certain day in the winter, two boys were born in the land of water and fire. One with beautiful white hair and blood red eyes, the other complete opposite pitch black hair and round black eyes. The story that goes beyond, we all know of. Yukimura, the Blood Medic and Niti, the Hellspitter. Reborn.
