In my opinion there are only 3 things that the reader needs to know beforehand or needs improvement on the authors side. Apart from those the idea is great and the grammar is way above most stories you find on this platform. And it's not just the AI generated bullshit that pops up everywhere. 1 - Ulquiorra is nerfed to hell and back, at least in the beginning (10% Ulqiorra = 10 Mio. Bounty Pirate) 2 - Heavy AU; dates, bounties, strengths etc can be all over the place. Although many are close to cannon there is hardly a chapter where One Piece fans don't read something that does not fit into at all. 3 - The ratio of explanations or thought monologues to progression is terrible. I didn't calculate it but it felt like 2:1 or worse. There is hardly any flow for the reader and that makes it hard to stay immersed in the story.

LIKEthat's why i added "in the beginning". While reading i was confused with the 10% strength being so low and saw many comments stating the same, that's why i mentioned it in my review. I read till chapter 24 so i knew his strength grows rapidly
