Carl swung his sword right, left, and in various directions to ward off her wind attacks. It came fast and alternating, so he couldn't take a deep breath to relax from the tension. It was intense and seemed to force him to hold his breath throughout his defense.
He felt the wind hit his arm. But he didn't have time to check because there was a lot of wind he needed to brush off. He moved as fast as he could, swinging the swords in both hands, though one was worse than the other. And he had no choice but to keep doing that. It was to get used to his body.
Another wind hit his thigh. He felt the cut, even though he was sure there was no wound. His shield. It protected him well, but Miku made him feel a bit of pain. Just a little cause it would disappear soon. She said it was to get used to his body to feel the pain.
Again, about getting used to his body. Yeah, the practice was all about that.
