Hey alan sup? Just a quick suggestions, for the MC in ZZZ character development. I suggest you do your research in their training arc(Based on the weapon Y/N using), it would be much more impactful and much more good if it based on a real life training. If you already planning that, then good.. keep it up.
And also, make some development through his personality in some way.. make him.. likeable but a bit more different (I already like it, but it lacks something i can't quite put my word into it). That's all I gotta say, hope you consider it!
