It's odd, I tried to make things difficult and fun for myself by playing on Hard and getting no upgrades (other than outfit), and it was fun to lose 3 times and then make it to the first boss on the 4th try, but I couldn't arrest him, even with generally high detection levels. Then, I lowered it to Normal, and even Easy, and I... cannot catch the boss?... Like, I have a pretty good grasp on how to win the game in general, but like, the enemies never run out and I can never arrest the boss?... I could experiment more, but uhh, what am I missing here?...
