Chen Shi opens his eyes again and finds himself back on the first day the evil spirits descended.
In his previous life, just after joining the Demon Slayer Bureau and becoming an honored swordsman, he encountered a Class-Zhou great demon on a mission. He was swallowed in a single attack, with no chance to fight back.
In this life, he is reborn with a Demon Slayer System. Not only can he summon members of the Demon Slayer Corps from Demon Slayer, he can also obtain their powerful Breathing Styles!
Having been given another chance at life, I, Chen Shi, swear to slay every evil spirit under heaven, especially you, Muzan Kibutsuji!
