So my thought is that the Kojin blessing... it allows u to breathe water, but like... the water still enters your lungs.
So i imagine the transition between breathing air and breathing water takes some getting used to. It probably feels like you're drowing the first few times, and I imagine there's a panic response you have to stamp down.
And then when you're on land again, you get to cough up two lungfulls of water to make room for the air you need to breathe now
All this to say, the Kojin blessing is incredibly useful but also probably incredibly uncomfortable
