I'm currently planning a new novel but something had been plaguing my mind recently. It's like this: The novel I'm currently writing is eerily similar to Three Meals of a Reincarnator (Transmigrated to a hellish place and got sent back to a monster infested earth that revolves around Hunters). My question is, is this considered plagiarizing? For background, while my W.I.P is similar to TMOR, it's only the transmigration and monster infested earth part. Although there are demons, they aren't really the focus of the story.
Questions about copying.
As long as you aren't passing of someone's written characters, world and words as your own. And you've created your own unique character, world and story design. No its not copyright violation.
What it can become is cliche or trope.
