The first episodes narrate the first missions of the protagonists. As the series progresses, they explain the background of some characters.
My opinion:
Plot → Typical anime in which each chapter develops a mission, except for some in which they explain the origin of the protagonist. Nothing relevant or interesting happens.
Setting → Nothing to highlight.
Characters → No characters stand out and their backgrounds are nothing special.
Conclusion: In general, it was a boring anime for me, because it gives the feeling that there is no interesting plot to follow. It is a generic anime with nothing to contribute.
