An Unbreakable Bond (Demon Slayer Harem X Reader)

Chapter 25: The Two Tsugukos

The sweat was pouring down your face and you were nearly out of breath. You panted heavily as you struggled to keep yourself from faceplanting into the ground.

"You're doing great Y/N! That was much better this time!!" Kanae encouraged as she came over and gently pat you on the back.

It was after that when your arms gave up and you face planted the ground. "H-Hah....th-this is....s-so hard....a-and I'm meant to do this the whole day?" You asked. Your voice muffled as you were speaking into the dirt.

"Mhm! You have to be able to keep up your total concentration breathing at all times! Even when doing such intense exercises!" Your teacher replied as you slowly pulled yourself back up.

Kanae had quickly got you to begin using total concentration breathing all the time. Tanjiro had began it the day you had left to meet the hashira, so he had a slight head start.

"Don't ever start doubting yourself! I know you can do this! You're getting much better! You managed to keep it up for a full hour this time! Small steps Y/N!" You were really lucky that Kanae was such a good teacher.

She always encouraged you and picked you up when you feel down. There wasn't a single moment where she would get angry or impatient with you.

And that you were thankful for.

"Y-yeah....I want to succeed for you Miss Kanae....I want you to be able to be proud. I don't want to waste your time." You said, causing her already beaming smile to widen.

"You are already making me proud Y/N!" She replied, her hand gently resting in your hair now as she gently rubbed your head.

You just bowed your head as a response, still trying to catch your breath. Once you did so, you got right back to regulating your breath. Calming it down and taking in as much air as you could.

"That's it....good job Y/N. Keep it going." Kanae kept on geeing you up as you used your total concentration breathing.

You felt you stamina building back up again, and soon you were on your feet and running around again. There was plenty of ground to cover in the butterfly estate, and there were two heavy rocks with rope tied to them so you could lift them up.

Of course they were really heavy, but you had grown really strong, even more so now while you were using your total concentration breathing.

All the while, Kanae watched you with a wide smile on face, jumping in every so often to give you some words of encouragement when she felt you needed it.

At one point, the flower pillar heard footsteps coming towards her. She turned to see that Kanao was coming to join her, the same stoic smile present on her face.

"Hello there Kanao!" She smiled and waved as Kanao flipped her coin, before bowing. "Have you come to join me? I am just training Y/N to use total concentration constant all the time! He is making good progress!"

She heard Kanao flip the coin again. "That is...good." The girls voice was really quiet. She hardly ever spoke anyway, but whenever she did it would make Kanae really happy.

They watched you for a little while, before you made your way back over to them. Your face and clothes absolutely soaked with sweat.

"Phew...o-oh hey Kanao!" You greeted the silent girl when you realised she was there.

She flipped the coin again, before bowing to you.

"You are doing so good Y/N! You're even managing to keep it up now! I think we've made great progress today." She praised you, which made you feel even happier. "We should get you changed out of those clothes though and let you wash. You're absolutely drenched with sweat! I'll get Aoi to set out some fresh clothes for you!"
