[Finisher Usage]
After seeing the usage of finisher on the section starting 00:43:857, you have to make some sort of consistency of those usage on kiai as well to feel more intuitive while playing the map. The concept of finisher should be same on this case in my opinion, so I suggest to either apply finisher concept of kiai to the last part or vice versa.
There is two way for this, choose what you prefer:
I highly recommend to apply the first way as to be consistent to the rest of the set, would be better overall in my opinion.
