Tatsuki Fujimoto has talked about in interviews that he was heavily inspired by Gantz, so Chainsaw Man is a really close one. There's plenty of parallels aswell: hyperviolent theme, alien;devil systems, sexuality, youth, nihilism, teenager protag, religious & apocalyptic overtones, and disposable protagonists.
That would be your closest bet besides Inuyashiki
I finished reading it and loved it so much I was wondering if there is any other mangas with same vibe and stuff like that! please and thank you
