I think they both injured each other and I bet the injuries were superficial. The only difference is, we got to see Fujitora a bit earlier than Arimaki. Arimaki also has ways to recover his ass after being injured. Whatever it may be bandage scaling was always dumb. Sengoku was barely injured during the MF war, and MFer was converted in bandages after the way, which makes no sense whatsoever.
Also, Im kinda humiliated top-rated logia in this chapter. Sabo's much stronger than Ace, and Im almost owned him with a simple arrow.
