He can even twist reality itself, warping the very laws of physics to his will.

Naruto Mitarashi. The abandoned child of Kushina Uzumaki, left to die in the village, after his father's death. All because his mother thought he was a demon. Abandoned by his godfather, because he wasn't the child of prophecy, abandoned by his father last student, because he reminded him too much of Minato.

Crossing over into the world of Cyberpunk 2077 should be an opportunity to make a big splash... Wait, hold on, isn't this the year 2075? Sure, it's already November, and 2076 is just around the corner, but I only know about what happens in 2077! In this world, you might not want to live, but you can't afford to not have a job. Anyway, let's start by becoming a mercenary and picking up gigs. That sounds simple enough, but getting a job from a fixer only to face off against an ACPA (Armored Combat Personal Assist) right off the bat-aren't we going a bit overboard here? And who's this daughter of Michiko Arasaka? I've only seen the demo; I don't know these people! What kind of chaotic mission is this!?

Kitazawa's grades at the Ninja Academy had always been mediocre. Uchiha Itachi graduated at seven; he barely scraped through at thirteen. Uzumaki Naruto became the savior of the ninja world at seventeen; at that same age, Kitazawa was still struggling to make Chunin. In this harsh world of shinobi, Kitazawa was what people called a fodder ninja: no talent, no bloodline, and no backing. To stay alive until the story's grand finale, he'd chosen the safest path-teaching at the Ninja Academy, a job he'd held for five years. "Another peaceful day in Konoha." Kitazawa rose from his seat and walked to the window. It was enrollment day again, and the training grounds were buzzing with life. He glanced down at the stack of new student files in his hands. Names leapt out at him, all too familiar: Uzumaki Naruto, Uchiha Sasuke, Hyuga Hinata, Ino Yamanaka, Sakura Haruno, Akimichi Choji, Nara Shikamaru, Inuzuka Kiba... and more. 'DING' 'Host has reached age six and successfully enrolled in the Ninja Academy.' 'Activating the Strongest Shinobi System.'

Kanda Kyoichi transmigrated to Konoha and became a temporary instructor at the Ninja Academy. Fortunately, he awakened the Mentor System. By teaching others, he could earn rewards. Thus began Kyoichi's career as a "teacher" in the ninja world. Shisui: "Sensei's unique interpretation of the Will of Fire has given the Uchiha Clan a true sense of direction!" Asuma: "The essence of the jade lies in protecting the people, with the advanced leading the way for the less experienced. Only then can Konoha become stronger!" Kakashi: "He's my life mentor. He transformed Konoha!" ... Years later, in the memoirs of Kyoichi, now the Hokage, he wrote: "I honestly just wanted to be a life mentor!"
