Made in Abyss Anime Series will get a second season on 2022. It is entitled as "The Sun Blazes Upon the Golden City". I wonder why season 2 though and not movie 4 since every arc in this anime is a movie worthy and people loved the movie the same as the manga or anime adaptation. Made in abyss is one of my all time favorite because of its mesmerising world building and dark story. People tends to overlook this series because of its poster that looks like a normal anime made for kids. But trust me you don't want to let your kids watch this show. It has a lot of things that contradicts its innocent looking cover.
Why Anime Sequel?
I have a feeling that Made in Abyss will reach its en esding soon. They are on the 6th layer and currently planning to go on the 7th and final layer where Riko's mother supposed to reside. And making a sequel is a great choice. They can make a movie soon if they want to, just like what they did on season 1. The movie are created 2 years after the anime but it's just like a recap movie version of anime series. So in this season, they might make a movie out of Ilblu Arc since it is a very good arc too.
Season one are love by many because of its faithful adaptation from manga. And this season is already expected to be as good as the quality of the first. They can focus more in detailing the story in anime series and focus more in animation for the movies. That'd make this show successful even though it is not popular in foreign countries.
What will the story cover?
This might be a confusing one. Even myself is not sure if they will start from Ido Front Arc. This arc is the entire Movie 3. So if they decided to leave the movie as it is and skipped directly to Ilblu Arc, it would just mean that you need to watch the movie in order to understand the story. Very similar to Kimetsu no Yaiba's Movie (Mugen Train) and Season 2.
Ilblu Arc is composed of 19 Chapters from the manga (Chapter 39 to 57). As stated in the title, it all happened in the 6th layer of the abyss at the city called Golden City. It is a layer of No Return since it is believed that no one returned to the surface after reaching this level. And as expected this level is entirely non-human at all. If you've watched the first season and all the movies, you'll notice that the Characters are getting less and less human as they descend to the deep of Abyss. The 6th layer is definitely mysterious and eerie that makes you think if it is the 6th layer, what can we expect to the 7th?
It only just showed that the Abyss is a place way beyond human limits. There are something more we can learn in their journey and there more mysteries yet to solve. What awaits them in the 7th layer? Will they found what they are looking for?
Made in Abyss is highly influenced by Friedrich Nietzsche quote, "If you gaze long into the abyss, the abyss will gaze back into you". And as the meaning of abyss, this anime has a very deep and philosophical meaning along with its dark and mysterious theme. Extending into a deep and wide world building. It only shows that Made in Abyss is a series you can't overlooked.
