All Jouno had to do in the scene where Chuuya throws the bullets is to activate his ability so they would just pass through him. The bullets can’t hurt him.
They can, however, hurt Tecchou. One of them even pierces his shoulder.
Which means this scene of Jouno slicing at the bullets to deflect them is 100% for the sake of protecting Tecchou. There’s literally no other reason.
Just look at the action lines. You can see how Jouno’s sword motion starts directly above Tecchou’s head, deflecting the bullets away from him.
But sure, Jouno, keep telling us how much you hate Tecchou. We know the truth
