"Kaa-san do you need help with anything?" I asked my Mother, I wondered if she was tired. She was working very hard around the house and I wanted to help. "Huh? Y/n you don't have to help me." Kaa-san replied back to me, I shook my head and replied with, "But Kaa-san I want to help you." I wanted to help even more now, she has to take care of me, Tanjiro, Nezuko and Takeo who was recently born.
She smiles and pats my head, inside I felt happy and warm, but outside I still looked emotionless. She puts a finger to her head and looks like she's thinking. "Well recently your Father has been feeling sick lately. We also need wood for fire, could you chop some logs please?"
"Alright Kaa-san, i'll see you in about an hour or two." She nods and continues to clean the kitchen, I turn around and grab an axe. I walk out of the house and travelled down the mountain a bit. I walk up to the tree and thought, 'I should probably use Total Concentration Breathing to cut this tree down.'
I inhale then exhale and swung my axe to the tree and cut it down, it was kinda hard to cut it down. Suddenly I fell down to the ground, gripping at my chest I cough rapidly. Without even knowing that I kept the Total Concentration Breathing up for a solid 3 minutes. 'Oh... well that hurt a lot. I guess I should finish cutting down some more trees. Then I can practice Total Concentration Breathing.'
==========
I just finished cutting down those annoying trees and I was kinda feeling tired. My lungs felt like they were going to explode, but it was useful in the future. I fell on my ass and coughed, I looked around my surroundings and realized it was already night. 'Oh, that's nice isn't it?' I heard movement from behind me and roll to the right dodging a Demon. "Hehe, look what I found a pesky Human to eat! Hahahah-" Before the Demon could continue, his head was suddenly sliced off.
I look around to see who did that and saw six eyes looking at me, ain't that great meeting an Upper Moon is nice. "Human tell me what's your name?" I look at him with a blank expression and replied with, "Y/n, Y/n Kamado." While watching what Kokushibou would do next he seemed to be in a deep daze.
'I see, could Yoriichi have possibly been reborn. If so I can finish my fight with him, but first I have to train him. Maybe he can even be able to do Sun Breathing, he looks exactly like Yoriichi. I'll train him and once he's strong enough we'll have a fight to the death.'
"So Mr. Super Evil Six Eyed Demon, i've been wondering which eye pair do you look out of?" Kokushibou seemed to be confused on his nickname but replied with, "I can see through all of them of course." I was still confused on why he has six eyes for. What was one pair to look after the other Upper Moons? Was the other pair to look at Muzan and the other pair to look at his sword? While I was dazed out Kokushibou's face was right in front of me. "What are you doing? Are you a Pedophile? Do you want to touch me fuckface?"
Needless to say Kokushibou knew he would have to teach him how to not swear. He was already getting annoyed with your insults, He stood up and looked away and said, "Y/n meet me here again when it's night time tomorrow." Y/n was confused but still kept his emotionless face. "What are you implying? Are you still trying to rape me?"
"No of course not, i'm not a Pedophile I want to meet you for training. And I saw you earlier tonight cutting down trees using Total Concentration Breathing." I nod my head and stand up, as I was walking away I heard Kokushibou ask me a question. "Hm? I didn't hear you what did you say." He seemed to be annoyed a bit but replied back anyways and said, "Can I call you Yoriichi?"
"Call me what you want I don't care." I start to walk away and then quickly start to run realizing my Family is worried for me. While running I started thinking, 'I wonder if I could persuade Kokushibou to betray Muzan and have him help the Demon Slayers.'
==========
When I arrived I was greeted with an angry Family and it didn't feel good. I basically was hugged for two hours, and I was dragged to Tanjiro's room. As I laid down Tanjiro started to cuddle me and fell asleep. I hug him closer to my body and slowly fell asleep.
When I woke up I started to head back out to where I met Kokushibou and started to cut the trees down. I improved my Total Concentration Breathing today. I can now use it for about 10 minutes but that's not even close to Twenty-Four Hours. "I see, you've been practicing Total Concentration Breathing." I swear he's gonna give me a heart attack one of these days.
