Chapter 3: Jigen
At that time, Kiyoshi, who had not yet awakened his past life's memories, had no idea what his awakened Otsutsuki bloodline meant.
In an unknown temple in the ninja world, a young monk-like man wearing a white haori, his hair gathered on top of his head with a long braid hanging down his back, a Roman numeral 4 tattooed below his left eye, and a black mark on his chin, was meditating and training. He wore a red neck gaiter and red wristbands, had black nail polish, a red belt around his waist, and red earrings.
The monk's name was Jigen. He lived in the ancient era thousands of years ago, an era even before the time of the Sage of Six Paths.
In ancient times, Kaguya Otsutsuki and Isshiki Otsutsuki came to the planet where the ninja world was located as partners to plant the God Tree. Originally, one of them would be used as a sacrifice to the God Tree.
Isshiki Otsutsuki's strength was slightly greater than Kaguya Otsutsuki's, so for the Otsutsuki clan, where strength was paramount, Kaguya was to be the sacrifice.
However, unwilling to be a sacrifice, Kaguya made a desperate move on the eve of the sacrifice, launching a surprise attack on Isshiki, causing the sacrifice to fail and Isshiki to suffer irreparable injuries.
But at that moment, a monk named Jigen happened to pass by in the distance. Seeing a glimmer of life, Isshiki Otsutsuki used his dōjutsu, "Sukuna Hikona," to shrink himself and infiltrated Jigen's body.
Isshiki gained a chance to breathe and, after slightly recovering a bit of strength, carved his "Karma" seal onto Jigen's body.
Just as Kiyoshi awakened his Shikotsumyaku and emitted an inexplicable aura, Jigen, who was meditating in the temple, suddenly stopped his training. His body involuntarily changed, and strange black markings appeared on his body and face, the initial stage of "Karma."
"The aura of a nascent Otsutsuki... the bloodline of the Otsutsuki has been born again in this world after a thousand years, although it is still very weak!" Isshiki's slightly excited voice echoed, "And, this is the aura of that lowly woman Kaguya! It seems to be her descendant."
"This is wonderful! A body with the Otsutsuki bloodline, even if it's just the most initial kind, is perfectly usable for my resurrection!" Isshiki's emotions fluctuated.
Jigen gained a long lifespan because he was marked with the "Karma" seal by Isshiki and became a vessel for Isshiki's resurrection. However, Isshiki's power was far too great for a native of the ninja world, and Jigen was just an ordinary monk from the ninja world. He could not become a suitable vessel for Isshiki Otsutsuki's complete resurrection, and he couldn't even exert Isshiki's full strength for long periods.
Therefore, Isshiki had been troubled for a long time by not being able to find a suitable body, a "vessel," that would allow him to complete his reincarnation smoothly.
It was no wonder that Isshiki was so excited at this moment when he suddenly sensed Kiyoshi's aura.
After all, this was a body with the Otsutsuki bloodline. Although the bloodline was weak, it already had a foundation. The weakness of the bloodline also meant low strength, making it the most suitable body for Isshiki at this time. If it were a fully evolved or complete Otsutsuki, like the Six Paths brothers of the past, or Indra and Asura, Isshiki would definitely hide as far as possible.
The sensed aura was in the far east. Jigen returned to normal, slowly stood up, and embarked on the journey to find Kiyoshi.
At this time, after driving away the two Jōnin, Genji returned to Kiyoshi's room with a complicated expression. Looking at his son, who was still unconscious on the ground, his heart slowly became firm.
"I thought in such a harsh environment, his body wouldn't support his awakening, but I didn't expect him to be so talented," Genji thought with admiration. "It seems he is destined to become a ninja!"
"Ugh!" Kiyoshi slowly opened his eyes and rubbed his groggy head. "Father, what happened to me?"
"You're awake, come and sit down," Genji's faint voice came, without any discernible emotional fluctuation.
Kiyoshi slowly got up from the ground, and the events that had just occurred gradually came back to his mind. He slowly walked to Genji, sat down with difficulty, the exhaustion of Chakra making him extremely uncomfortable.
"Can you still use the Ten Finger Drilling Bullets from just now?" Genji asked.
"Ten Finger Drilling Bullets?" Kiyoshi asked. "What's that?"
"It's the ninjutsu you used to break the wall just now. It's a ninjutsu that shoots high-speed, penetrating bone bullets from the fingertips of both hands for attack," Genji explained.
"I'm sorry, Father, I only saw bone spurs emerging from my fingers, and then I fainted," Kiyoshi replied apologetically, feeling slightly embarrassed.
"Indeed, a weak body coupled with the newly awakened Shikotsumyaku," Genji said, not surprised. "But to be able to instinctively use the Ten Finger Drilling Bullets just after awakening, your talent is far greater than mine."
"Alright, let's leave it at that for now. Go and rest, recover your Chakra. We'll talk about any problems tomorrow." After saying this, Genji got up and left Kiyoshi's room.
"Yes, Father," Kiyoshi replied respectfully, suppressing the urge to know the details. Since Genji understood what had happened to him, there was indeed no need to rush.
"Shikotsumyaku, is that the name of the ability my body produced?" Kiyoshi wondered curiously. With a mix of apprehension and curiosity, he slowly drifted off to sleep, falling into a deep slumber.
In this remote area, Kiyoshi's sleeping body slowly became tinged with a divine light, once again emitting an inexplicable aura. Apart from Isshiki, who sensed the Otsutsuki aura, no one knew that a boy in a remote part of the ninja world, while awakening his Kekkei Genkai, had also experienced an initial atavism of his bloodline, becoming a nascent Otsutsuki.
