There don't seem to be many stories about them. Stories about one person or the two of them are both fine. I'd also like to read a story about Kokushibo and his wife from when he was human. Please recommend something (´⌣`ʃƪ) Thank you.

Looking for stories like "Upper Moon One Is Still Taking Care of Kids Today". I've read a lot lately, so I'm not really in the mood for stories where someone cosplays as or transmigrates into Michikatsu. I'm open to stories with different styles, teachers, or a pairing with him. I'm in a serious reading slump lately.

I'd rather not have too many original characters or elements, and no original-character harems, either.

The plot is good, and the writing is also decent, but some settings are incorrect. Yoriichi wasn't a successor of Sun Breathing; he was its creator, and all other breathing techniques are derived from it. Yoriichi only taught the other demons breathing techniques after joining the Demon Slayer Corps.
The author writes very well, the characters aren't too out of character, and the everyday life depicted is very ordinary and sweet. Kokushibo Tsugikuni isn't as obsessive in this story, which is exactly the kind of lifestyle I wanted for Kokushibo Tsugikuni and Yoriichi Tsugikuni. The sun and moon should shine together! ❤️😢
The author writes very well, it's sweet and heartwarming. Although I'm looking forward to the later plot of the "Infernal Affairs Plan," the author must have his reasons for ending it this way. Perhaps the ending where everyone knows they'll win is the best ending? (PS: No malice intended, no plot planning. I'm actually relieved, even though I know it's fiction. The two little bitter gourds in the original story were already so bitter, let me read some fanfiction to sweeten things up!!!)
It's good, but I feel like Yan Sheng can't let go or be at peace with it, so I always felt something was off while reading.
The writing is very good, but some parts might not match the original anime (those who don't mind can take a look). Also, the ending is a very open-ended E-O (the later plot isn't written, it's a very open E-O). Furthermore, Yan Sheng truly lets go of his obsessions in this book (he lets go very openly, even feeling proud of his younger brother).
The Tsugikuni brothers finally understand each other's thoughts, and Lord Tsugikuni is the most human-like character I've seen so far. Yoriichi shows signs of intellectual awakening, and Mikoto's second playthrough made up for many regrets I had when reading the original work—it's so sweet 🤭
I'm still really looking forward to what comes next. I'm still looking forward to the rest of the story, but I feel that Yan Sheng and Yoriichi in the book are a bit weaker than in the original work. [Currently rushing to finish the manuscript]
The lividity has faded, and the two little ones are so cute!
The plot is good, but it's a bit out of character (OOC).
Seriously, this book perfectly captures the atmosphere I envision for the two brothers. Looking forward to it!
