When Yasui Ryosuke is transported to the world of Demon Slayer, he is devastated.

Good news: He is familiar with the original work and knows the plot.

Bad news: The original owner was a sickly person who was not long for life, and the only cheat was the double-dealing system that required spending a lot of time and effort to become stronger!

"You mean killing demons grants you lifespan, which can then be used to enhance your breathing technique and sword skills?"

Yes, that's right~

How much longer can I live?

[Congenital liver failure, at most one year, haha~]

Yasui Ryojie was angry.

Knowing the original plot, Ryosuke would never willingly seek his own death by joining the scoundrel Muzan.

If that's the case, then kill!

Kill them until the sky darkens...
