In a training ground, a five-year-old child can be observed practicing taijutsu. 'Byakugan,' exclaimed the boy, as he performed the Hakke Rokujūyon Shō (Eight Trigrams Sixty-Four Palm). This technique involves targeting sixty-four specific chakra points on the opponent's body with the gentle fist, effectively impairing their chakra utilization and impeding their movement.
The process entails sequentially disabling two chakra points, followed by four, eight, sixteen, thirty-two, and finally sixty-four strikes, with an accelerating speed for each set of strikes.
Despite his efforts, the boy acknowledges his need for greater strength to survive in the turbulent world of Naruto.
His words and demeanor reveal that he is from another realm, specifically a transmigrater who originated from a planet known as Earth.
In his previous life, he was an ordinary 16-year-old high school student. Similar to other transmigraters, his untimely demise occurred when he was struck by lightning while commuting to school on his bicycle, along with his umbrella.
[FLASHBACK]
In the subsequent months, he encountered numerous challenging experiences, such as soiling his bed and nursing from female breasts. It required a time span of six and a half months for him to acquire proficiency in the Japanese language and articulate effectively. Additionally, it took him one year and three months to achieve unrestricted mobility, earning him the esteemed reputation of being a prodigy within his clan.
Regarding his lineage, his father perished during the rebellion against the nine-tailed demon fox, while his mother tragically passed away during childbirth. Despite his limited knowledge about his parents, he expressed profound gratitude towards them for bestowing upon him a fresh lease on life. Fortuitously, his grandfather held a significant position as an elder in the Hyuga clan, resulting in him being exempt from acquiring any restraining marks (cage marks). Furthermore, he shares the same generation as Naruto.
When he reached the age of three, all the children from his clan, who were of similar age, were gathered within the extensive training facility. The primary objective was to educate them on the art of refining chakra. During this time, a member from the branch clan named Shinsuke approached and presented him with a scroll that provided instructions on chakra refinement. As soon as he obtained the scroll, he promptly commenced the process of honing his skills.
And due to his remarkable intelligence surpassing that of a three-year-old child, he successfully learned the art of refining chakra within a mere three hours. The observant clan members, who were present during this impressive feat, were astounded, as no one in their entire clan had ever achieved such rapid chakra refinement. Ren was held in high regard as an unprecedented genius within the clan, and news of his accomplishment quickly spread throughout the leaf village. It became a widely-known rumor that at the tender age of three, a prodigious Hyuga had accomplished the feat of refining chakra within three hours.
After completing his chakra refinement, Ren joined the other clan members who had been observing the children. As evening approached, the elder members of the clan brought forth the children from the branch house, and to Ren's horror, he witnessed the immense suffering inflicted upon them through the placement of the cursed seal. This seal granted the main house members absolute control over the individuals from the branch house.
One month following the completion of his refined chakra training, on the day of his daughter Hinata Hyuga's third birthday and the day the peace treaty was signed between Konoha village and Kumogakure village, an event occurred. The squad that had arrived in Konoha for the peace treaty was invited to Hinata's birthday celebration. However, an attempt to kidnap Hinata was made, but was thwarted by her father, Hiashi Hyuga, who killed the would-be kidnappers. Subsequently, the Head Ninja of Kumogakure demanded Hiashi's corpse, as dictated by the terms of the peace treaty. It was Hizashi who ultimately sacrificed his own life for the sake of the village and clan, sealing away his Byakugan upon his death to prevent a war. This incident, known as the Hyūga Affair, brought about significant changes in the behavior of Neji, Hizashi's father, and the other members of the branch clan."

Just as he was about to depart, he experienced a momentary disappointment when a voice suddenly resounded in his mind:
