Once through Demon Slayer: Kimetsu no Yaiba, Lin Yuan, a doctor of biology from Tsinghua University, originally wanted to use science to cure the sick boy.
Unexpectedly, the "Kowloon La Coffin" fitness package was so awesome that it actually turned the patient into a ghost king - Oni Wu Tsuji Muzan!
A big mistake was made. In order to correct the mistake and protect himself, Lin Yuan used stronger medicine on himself!
From then on, there was one less doctor in the world who could save lives and injuries, and there was one more... One who walked under the sun, used "science" as a weapon, and hunted his own "creations"...
The perfect ghost king!
