A technique for sucking in Chi from the air. When Firo tried to copy Naofumi and Atlas, and was immediately able to grasp Musou Kassei by copying Firo and Naofumi.
Even though Firo had experience using the pose to recover magic, in just a day of practice, she learned to suck in Chi and move around, conveniently obtaining power easily. What’s more, it seems that Firo subconsciously activated Musou Kassei. Her movements are quicker than before.
The Musou Kassei that Firo and Atlas picked up is somehow different from the one Rishia used, because they only learned through observation. Even so, Rishia says their skill is not inferior.
And no matter how long Firo can keep Mussou Kassei up, there’s still a limit. Using only internal Chi, it’s one minute. While taking Chi in, five.
