Yeah. I never get tired of them, to the point I started to unironically creating a scenario in my head where I'm a hidden character in any isekai or fantasy title that I'm reading where I'm the unknown but all-powerful one.
Oh wait, there's already an isekai title for that one too.
God I feel like I should create my own isekai stuff and post them on shousetsuka ni narou or smth. I'm pretty sure the japs would never get bored of this genre.
