The next day.
Kanzaki Kumo's special training for Kanae officially began.
It was broadly divided into four areas: swordsmanship, reflexes, Breathing Styles, and stamina.
But Kanae had only spent a limited amount of time learning Breathing Styles. Her mastery of Total Concentration Breathing lagged far behind Makomo's before her, and her body had not been fully strengthened by her Breathing Style either.
So he reduced the intensity of her physical training and added more Breathing Style training.
This time, Kanzaki Kumo brought out another prop-a gourd.
That was right, the same kind of gourd the protagonists used to train their Breathing Styles in the original story.
In fact, Breathing Style training could be seen as training lung capacity.
Ordinary people, however, generally trained their lung capacity through deep breathing, aerobic exercise, and the like, along with simple resistance breathing exercises such as blowing up balloons.
For the Demon Slayer Corps' swordsmen, that level of training was not enough.
So a set of gourds in different sizes made for useful training aids.
Once Kanae successfully blew apart the gourd that stood over a meter tall, it would also prove that she was capable of mastering Total Concentration: Constant.
The morning still focused primarily on swordsmanship training.
Besides pointing out the openings in Kanae's techniques, he also needed to help her develop new ones.
Since Kanae had created Flower Breathing herself, there was practically nothing unnatural about her movements, which set her apart from Makomo.
But precisely because she had created it herself, using only Water Breathing as a reference, it contained some movements unsuited to actual combat.
These arguably unnecessary movements would not cause problems against weaker enemies and even made her techniques somewhat more deceptive.
But against an equally strong or stronger opponent, those extra movements meant extra expenditure and
