This has gotta be one of the best animes I have seen. No stupid side characters, no meaningless episodes, and no “fan service” of literal fracking teenagers (I hate that one’s in like half of all animes). Just great animation, a straightforward, understandable plot, and shockingly good, consistent worldbuilding.
Most popular animes take place in high-school settings or utilize high-school aged characters. They also use fanservice to try and appeal to the audience. This practice is generally hated among most anime fans.
While fanservice can mean any number of things, for anime, it generally refers to the sexualization of a character.
I like how it focuses a lot more on the journey and the worldbuilding than on instant gratification like most modern anime tend to do.
There’s an actual story to be told here, with a tone that is primarily lighthearted but at the same time not afraid to get really dark when it needs to.
