Recommend me a seinen manga or anime that has sci-fi, fantasy, or otherworldly elements

Shonen is ok too if it has immersive worldbuilding.

My favorite manga of all time is “Blame!”

Currently I’m following Paralel Paradise, Frieren, Hell’s Paradise, and Boruto manga, though that’s shonen.

I do like classics such as Beserk, Claymore, Stein’s Gate, Eureka 7, Shinsekai Yori, and To Your Eternity.

Is there anything newish out there that I might like? I think I’ve seen most things pre 2020
