Twins on Different Paths: Yueyan and Wuhan's Bond of Atonement

I expanded on his background based on the image and life experience of Onibatsuji Muzai in the original Demon Slayer: Kimetsu no Yaiba, which is equivalent to making a complete story line on the reasons for his cruelty, self-centeredness, cold-bloodedness, etc. I also added a new character, Tsukiyan Muzai's younger sister. Friends who are interested can read it. Personally, I think this fits well with the original work, and it further deepens Demon Slayer's thinking. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
