Preferably Manga (anime only is fine tho) similar to Gachiakuta

It's been a while since I binged a manga. That flow state where I turn on my phone whenever i have a free moment and just keep reading forever until some outside force stops me. Recently I've been looking for something to fill that void, the last one was Iruma-kun which was fire, but ever since I've just haven't found anything that held my interest. I work an office job with downtime so I was bored and just decided to read something that was currently airing it's anime at the time, Gachiakuta. It was on a whim, but I finally found that flow state again. The story itself isn't even anything groundbreaking or anything, It's just good. Like good good, not whatever good (the art is great too). I need something else like that, not necessarily dark fantasy/gritty dystopia, but something with a good main cast, the cast has chemistry with each other and not just the MC, the world building and lore is growing, multiple factions and mysteries and a good balance of fun and serious. To give context, One Piece is my goat, and I'm into a lot of shonen/seinen manga like kingdom, HXH, Berserk, Iruma and ichi the witch, Dandadan, among others. I've given dorohedoro a chance but didn't like the vibe, and tried some shojo stuff like akatsuki no yona but gave up around 50 chapters in.
