Time always slipped away especially quickly when people weren't paying attention.
Before he knew it, Kanzaki Kumo had spent another month and more at Gyomei's place.
Mitsuri's physical training progressed as usual, with some flexibility exercises specifically arranged for her added in. After all, her fighting style demanded a great deal of flexibility; sheer strength alone wasn't enough to wield that flexible blade several meters long.
Kanao's Breathing Style instruction was also complete. The rest would depend on her own hard training.
Kanzaki Kumo didn't need to worry about that. To be able to help him as soon as possible, Kanao trained even harder than those two Grind Kings, Tanjiro and Muichiro, to the point that Kanzaki Kumo never urged her to train, but instead urged her to get some rest.

There was no helping it. Without the support of a Breathing Style, Muichiro really could have ruined his body with training that intense.
