Beginning disclaimer: I read this in French, not in English. This is a good series by the creator of studio Ghibli. It was written and even had a movie adaptation before the studio was founded, back in 1985. Therefore, this story is slightly darker (?) story line, as people do die, and it does include full blown war. However, it does keep a lightness to it, and has many similar traits with most studio Ghibli, such as a fascination with things that fly and robots/artificial life forms. It has a decent plot, and many things happen. There is some plot armour, but it's not terribly heavy. I enjoyed ready through this detailed fantastical world that, despite not having colours, felt vibrant with life. I hope you enjoy this series as much as I did.
