There may be some OOC moments, so please bear with me.
The story will later transmigrate to other worlds.
Yang Yuan was a fine young man from the 21st century. One night, as he walked home alone, a road roller fell from the sky and crushed him to death. When he woke up, he found that he had transmigrated into Demon Slayer.
Looking at the Stone Mask and Aja Stone in his hands, Yang Yuan fell into deep thought.
(This is my first time writing a novel, so please don't flame me if you don't like it. There'll be all sorts of references later, so don't think too hard while reading.) There will be Stands and Hamon.
There may be a heroine (it's only a possibility). It could be a single heroine, or there could be multiple heroines.
