In a dark room, a boy no older than 15 was sleeping soundly in a single person bed.
Suddenly the boy got up Gasping for breath, he clutched his right eye with his two hands, lightly screaming in pain as blood trickled down his right cheek.
He went to the bathroom and turned on the mirror before removing his hands from the bloody eye, the eye was red in colour, slowly rotating as several rings started forming in said eye, many comma like marks appeared around the different rings formed in the eye as it gained a purple pigmentation.
Ayato looked in the bathroom mirror to see that his right eye had transformed into a rinnegan, the left was untransformed and attained the Sharingan's red pigmentation but another unknown pattern, A 9 pointed shuriken with a hole in each of the 9 circles.
His vision was clearer now, he could see chakra around his body and the natural energy present in the environment. He could see every movement slower now, every twitch in his body, every vein pumping blood, he could perceive all of them.
Ayato felt his life energy drain out of him as he deactivated the eyes, gaining control over them.
'What the f***, Rinnegan? I expected to get mangekyo or Eternal mangekyo but this is too much, the rinnegan can easily strain my body and kill me, draining my life force.' Was the thought in his mind.
He looked back up again, The chakra flow slowly stopped as his eyes reverted into his onyx orbs, the rinnegan disappeared alongside his Eternal mangekyou.
Ayato took a moment to look at the palm of his hands and again in the mirror with his right cheek dyed red from the blood tear from his right eye. He felt dizzy before passing out in the bathroom.
As soon as Ayato woke up, it was already morning. He looked in the mirror again, cleaning his blood stained face first before examining his eyes, he pulled an eyelid back to inspect his eye, finding nothing wrong in it the eye, he transferred chakra into his eyes.
Both of his Eyes started out with the base Sharingan before rapidly spinning to form a nine pointed star, He felt memories rushing inside his head, telling him the names of two Japanese gods.
Fukurokuju...
Jurōjin...
His mangekyou abilities, The first Fukurokuju in his left eye allowed him to cast a Genjutsu on himself and any other person, allowing for exchange, lending or borrowing of life force from someone who volunteers to do so consciously, By borrowing it can also mean that life force can be stealen by Ayato if he has knocked the victim out, the stolen lifeforce will be transferred to the victim if it is alive, otherwise the lifeforce will be converted into natural chakra when the user of Fukurokuju dies.
His second ability, jurōjin in his right eye allowed him to heal injuries fast, the cost is a certain amount of longevity that he has. If he takes a fatal injury it will take double the time it will take to heal and if he takes a life threatening injury then half his original lifespan will be taken, he can use this technique to heal others but at the cost of double the lifeforce it took to heal himself.
These two skills perfectly complement each other and can be used without any reprecautions.
Ayato transformed his right eye into the Rinnegan and immediately felt a sharp pain as his eye started bleeding due to the strain but he could see all things and chakra clearly. Upon closer inspection, he could notice a small pathway of chakra in his body, the 50 percent of all the chakra in his body was directed into his eyes. That's how much strain he had when just activating the eyes but only could imagine the cost of doing a chibaku tensei. He shuttered In fear.
Like before a new memory made it's way into his mind.
Deva Path...
Ashura Path...
Human Path...
Animal path...
Preta path...
Naraka prath...
Animal path...
The powers of the paths remained just like he remembered them but he felt that the chakra cost of each of this moves was way higher than his chakra pool, which had also expanded tremendously, he would put his chakra at elite jounin level. Moreover, his body had also strengthened tremendously, every action he did was easier, but his chakra control did become way worse than he remembered it to be.
After walking up properly and doing his morning errands, he went to the outskirts of the village, near his house to practice his abilities and chakra control.
