Kindred in the World of One Piece

This book relentlessly vilifies the navy while simultaneously having the protagonist fawn over them. You can either write a more positive characterization of the Navy so the protagonist doesn't find it offensive to fawn over them, or you can harshly criticize the Navy so the protagonist is decisive and ruthless. Look at the Navy's lines.

Why didn't they kill the naval admiral who framed the protagonist? Not killing ordinary naval personnel is understandable!

I prefer optimistic and cheerful protagonists; this noodle stall guy is out of the question—it's just the author's repressed fantasy. They wanted to create a cool and aloof character, but their writing couldn't quite capture it. Adding him to my blacklist. You've poisoned my mind, so I'm saying something. No offense intended, just stating the facts.

Isn't Kindred a girl? ( •̥́ ˍ •̀ू )

Here's a suggestion: the protagonist is already this powerful after only twenty-odd chapters, his strength is increasing too fast. You won't be able to write a long story like this. Also, he's always fighting alone, and there's not much plot to see.

The archer theme is good, keep it up! (ง •̀_•́)ง
