(author's note, I will be speed-running jjk because the ending's not out yet, so I can't do much, plus MC is OP, so... have fun reading)
commentMC pov: The next morning, after my daily hunt, I decided that I had gained the following abilities. curse energy protection .super body which Buffs all aspects .curse reinforcement curse energy absorption curse energy transformation which allows the user to change every part of the body .absorption allows the user to absorb anything, such as matter-energy, into anything else in convert it to either curse energy or just do it for copying and usage curse technique set allows the user to copy both physical and curse technique abilities from the target Curse technique adapt allows the user to adapt to anything after a period of 1 minute after the attack has registered the abilities function curse technique Soul manipulation can be evolved with the technique Soul Hit, owned by the technique, one of Jujutsu kaisen MC's .cursed technique Thief allows the user to steal anyone's technique after physical contact curse technique indestructible allows the user to be indestructible whenever active, similar to Infinity, every part of the body, even the soul invincible, trains massive amounts of cursed energy, not an issue for the host, as this will grow cursed energy Reserves after it is used MC POV:
With all these abilities, I crafted a human appearance for myself before preparing to enter the human realm using my Ten Shadows Technique. Though it was technically my own, I still needed to acquire it from its original owner. That meant either waiting until Megumi obtained it or stealing it within the era I was currently set—the Golden Age of Jujutsu. This period was extremely dangerous if I wasn't careful, and unfortunately, none of the overpowered characters from the anime, like Yuta with his copy technique, existed here yet. The best way I thought about this was every time I went to sleep I would skip either 100 years or 200 years and I wore a few characters I did want to get techniques from Full, but first off I would have to allow sukuna to go on his Rampage in his conquering of the world after all he was fairly useless after is techniques were gone first I plan to get the electric guys technique after conjugate took his soul I could just take it by getting the technique or a copy of it tender was the copies of every other good Master out there remember 10 people did impress sukuna at that time so if I could get their abilities at least sore techniques and other such things I could at least have some broken abilities at the start of Jujutsu kaisen, I shall do a little bit more training before I get into it I do have a hundred years before sukuna debut "time skip" 100 years, during this time I have killed over 1.43 million curses remember this realm has an infinite amount being born every minute there's no end to them they all kind of coexist in the realm there's no need for food send everything in here cannot die any food cuz they're curses after the long and drawn-out time between every fight my curse energy Reserve has grown significantly it's so large in fact that it's in yuta combined and then multiplied by over 100 level of curse energy Reserves I could easily crush the entirety of Japan with my pinky finger I'm so powerful in fact that if I really wished the world could be destroyed fairly easily sukuna ruled that which I could destroy the world should come to fight me.
