everything before chapter 17 somehow, I managed to read it, but it's the worst experience consider I thought this was avatar fanfic and got little disappointed bro these 17 useless chapters.
sorry for the confusion, it's a multiverse fic with the first 17 chapters centered around kc's homeowlrd (which is a mix of hentai and slice of life anime) and he would be returning to it. The first world after this is avatar (210 chaps) and then the homeworld, and then black lagoon x???
