I'm glad to read that you enjoyed this anime and was surprised to learn that it was the first series you watched of this type.

For me it turned out to be unique, mostly because of its plot, in my opinion it mixes themes like The Matrix and other things, it made me doubt what reality really is.

As for its seasons, it not only has a second part but a third season will be released soon, so I recommend you to catch up soon to see the premiere with the rest of the world XD

Cheers! thanks for sharing your experience!
