Red thread of Destiny? Nah the thread it's blue
Gojo Satoru is the honoured one, the chosen by the gods and the one whose world changed just for him, there's only one problem though, he's bored
Satoru can see everything with his six eyes which means theres nothing new or interesting for him to see.
The Honoured one is bored out of his Mind, not even walking around the cities closest to the gojo clan or exorcing some curses here and there is fun anymore, Satoru Gojo is bored and he just felt a strong electric cursed energy coming from the middle of a mountain close to him, so he's going to do the obvious and investigate 'there's nothing more interesting anyways'.
Hatake kakashi has been reborn after dying in the war against Kaguya, and he's bored, he realized when he was 2 who he was (and that he still had both,both sharingans and wasn't that a surprise) and that there was some kind of chakra in this world, the difference being that it was more like mud instead of the felling of water chakra gave, during 3 years kakashi focused on training with his cursed energy (like his "mother" told him) and found that he could basically do the same he did with chakra, and the best part was that he had much bigger reserves than in his previous live (don't get him wrong he had a stupid enormous pool of chakra in his past live, but the chakra got drained just as quickly and now he didn't have a sharingan always draining his reserves which helped a lot), the more he trained the more he noticed the strange energy in the air, it wasn't quite like the ones every person alive had, it was more grotesque, more disturbing than the previous one
After Kakashi started training with the sharingan (after not touching that subject for 3 whole years after finding out he still had them) he managed to see all of the weird blobs of black energy that impregnates his senses all the time he gets out of the safety of his house, (cursed energy is a bitch,) he even started seeing them without activating the doujutsu which was a good and bad thing at the same time.
but them at his 11° birthday a rather strong curse entered the mountain and killed Kakashi's "new mother" (now, kakashi never felt anything to his so called mother, he simply viewed her as the woman who gave birth to him) in his daze to simply exterminate the monster from reality he used raikiri causing a tremendous flash where he stood and obliterating the upper body of the monster, making it turn to dust in the next seconds
Kakashi was ready to go back to the comfort and safety of his house to waste the rest of his birthday away when he felt a powerful presence at his left
Kakashi turned around slowly and looked blinking at the eyes of the person who was able to pass his sensors until being so close and was met with beautiful sky-like eyes, the boy in front of him was stunning beautiful with white hair and the contrast between the blue blue of the boy's eyes and his white eyelashes made him have a stunning appearance
The boy was wearing white shorts together with a short sleeve black shirt which adorned a hood, the boy was looking at him with a intense gaze, kakashi stared back and said with uncertainty "hi?"
The boy beamed at him
