The only ones I know involve the protagonist going to a post-apocalyptic future, like 7 Seeds or in a sense Dr.Stone, or from the past to our present like Thermae Romae. I don’t think there’s any real series from the present to a Cyberpunk/Sci-Fi future, the only one I know of is a hentai (I heard the plot is actually decent, but it’s still porn in the end).
