Holy shit Rivaille is NOT USING GAS when he hunts these two titans instead he’s using centrifugal force that’s why he had to do that crazy spin.
See?? SEE??
have some hanji example
Dude, he really is quite efficient in his gas usage and combatting techniques. I mean, all the spinning he does? It increases the length of distance that his swords make through the air before contact with enemy, meaning more acceleration, which means more force applied to the slashing, which means cleaner cut and less friction that dulls his swords.
