Full name: Ryōmen Sukuna
Powers: Most of Sukuna's powers are unknown, but he will have all his skills/powers that are stated in the wiki. He will also have Senjutsu and Youjutsu.
Story: The story will start approximately 1000 years before canon, in old Japan. He will meet with characters from Jujutsu Kaisen and DxD Universe. It is not stated when The Great War starts and Devil Civil War was like 500 years before canon. Also, it is not stated for how long The Great War was kept going. So mostly, before the canon starts, there will be a lot of events/ bullshit that didn't occur in canon. And true to Sukunas title of the King of Curses, he will have some subordinates (as a king should) and some abilities related to actual curses. There will be no harem in this story, but there will be a romance with one person (Tamamo-no-Mae).
Personality: I will try to not change his personality a lot. He will be the same selfish, immoral, exceedingly sadistic, and cold-hearted. Only exceptional to all this will be Tamamo-no-Mae. It is just the DxD world, thus there can't be a protagonist without at least one person who he will cherish. It is also more interesting this way. Sukuna is a highly intelligent and manipulative being, so if he finds that something/person will be useful to him in some way, then he will use it. Also, it is stated he is just selfish, so it's not really like he can't like or love someone, it will just be something unique from how others do it (basically, don't use a normal human moral compass to compare to Sukuna). Also, he is extremely prideful, even arrogant, but that's because he has tremendous power and he has been in this world for quite some time, so it's normal. Still, he can acknowledge worthy enemies or enemies who have the potential to become stronger.
About the story/goal: Sukuna doesn't really have any apparent goals. If he feels upset, he will go and start yet another massacre. So he doesn't have any real goal in his life, he just lives without thinking about the consequences of his actions. He will actively participate in canon, so it ought to be interesting.
To readers: If you have any suggestions on how I should improve this story, then you are free to write about it. Also if you have ideas about characters/powers/skills that I should add, and they won't destroy canon (completely), then I will consider adding them. Also, I can take normal and reasonable critique pretty easily, so If you have to say something about that, then feel free to do so. But just saying, that this is my first story, so don't be extremely harsh. Thanks in advance.
