2 seasons?

Unless they're short chapters/long episodes/low dialogue this is a 3-4 cours show based on the volumes and a 3-5 cours based on the chapters without cutting too much content.

@WestOnAndrewAve It's Netflix though, it has to do really well to even get renewed. Which has me worried for Blood of Zeus, which is anime in name only, but is a cool Greek mythos angle (even if those have had a resurgence since Lore Olympus, practically)

This show already got a second batch of episodes confirmed before it even premiered, and yes it's 12 per batch.
