Was the main character of this animation very strong but very low-key, making people mistakenly think that he was very weak?

Hey, I recommend you to watch One Piece: The Beautiful Navy. Although the main character, Brian, looked cute, he was actually a very powerful and beautiful navy officer. He was stronger than people imagined. It was precisely because he did not like to show off his strength that he was considered a very weak person. I hope you like this fairy's recommendation. Muah ~😗
