Butterfly Estate ~ Several Days Later

"Full focus breathing?" Tanjiro tilted his head to the side, slight confusion glinting in his eyes.

"Yep. Essentially, it means to keep up full focus breaths constantly, even while you sleep." (Y/N) nodded, having Tanjiro, Aoi, Zenitsu and Inosuke sitting before him.

"But...how are we supposed to achieve that?" Aoi asked, confused.

"Uh..." (Y/N) sweatdropped, his eyes shifting around rapidly. He'd mastered it without even knowing it, so...he wasn't really a teacher...

"If you continue to do full focus breaths throughout both the day and the night, you'll realize that your base stamina will rapidly increase. If you continue to practice that form of breathing, your body will eventually memorize that breathing pattern and allow you to perform full focus breaths all the time." Shinobu raised her finger to the side, standing beside (Y/N) as she explained what full focus breaths were. She also made sure to shoot (Y/N) a smug smirk, getting an eye roll from him.

"That's the basic jist of it, yeah. Basically just keep practicing that all day and night, no matter what you might be doing. I'm looking at you, Zenitsu." (Y/N) deadpanned, before he began turning.

"Where are you and Shinobu-sama going, Master (Y/N)?" Aoi asked, seeing the two wielding their swords and seemingly prepared to head out. Beside her, the boys dispersed and went on about their days.

"We've got to go and report to Oyakata-sama about something we learnt during the last mission. Just focus on mastering the full focus breaths. Kanao already mastered her Full Focus Breathing, and I've instructed the girls to make sure you practice." (Y/N) suddenly smirked, hearing screams echoing through the Estate along with bashing sounds.

"I should also mention I gave them special permission to use force. Excessive amounts of force." (Y/N) cackled, hearing the screams of bloody murder from the three who had dispersed prior.

"Isittolatetogobacktobeingahousenurse?"

"No takebacks." (Y/N) gave Aoi a seemingly innocent, yet menacing grin, almost as if could read her thoughts.

"Hai~ hai~, don't bully the younger ones so much, (Y/N)-san." Shinobu rolled her eyes, walking out of the Butterfly Estate with an amused smile plastered on her face.

"You're not my mum. Oh, and Aoi, tell Tanjiro and Inosuke that their new blades have been ordered, so that they don't need to use the standardized blades anymore. Later~!" (Y/N) then left the Estate, leaving Aoi to her own thoughts and joining Shinobu outside.

"Man, it sure is hot out today." (Y/N) remarked as he walked out of the Estate gates, closing the gates behind him and walking up to Shinobu.

"Well, you're usually supposed to be burning in the sun~." Shinobu teased, getting a small chuckle from (Y/N).

"Don't remind me." He laughed as the two then turned towards the road ahead.

"By the way, do you know where Oyakata-sama is? I didn't pay attention the last time." (Y/N) deadpanned, staring at Shinobu hopefully.

"Mou~ that's not very good. You'll have to memorize the way there, after all. Only Pillars are given the right to know the direct path to Oyakata-sama's Estate." Shinobu smiled empathetically, patting (Y/N)'s shoulder as a tick mark formed on his head.
