Black Rabbit Brotherhood 2nd Fight

I gotta be honest, I've loved this game so far. The bosses range from relatively easy to incredibly challenging (king of puppets was a real wall for me), but I've felt like pretty much all the fights felt good to slowly master, even if I struggled pretty hard with them.

However, I'm honestly about to walk away from this game. The first black rabbit brotherhood fight was the worst in the game so far, but it was fairly easy, so I gritted my teeth and got through it pretty fast. I got to the second one now, though, and it's honestly awful. Like truly, and really terrible. It's so ball bustingly hard that I'm clearly going to have to spend a long time on it, but that's not the issue, the issue is that every second of the fight is scientifically purified anti-fun.

How did anybody keep their enthusiasm for this game through this fight? If this fight were anywhere in the first half of the game, I honestly would have dropped the game. I'm currently considering not going back because of how completely unenjoyable the last hour of trying this fight was. Am I missing something? Did everyone else actually somehow enjoy this?
