Demon Slayer: I Lie Flat, but the Childless Brother Overhears My Thoughts

After transmigrating into Demon Slayer, he becomes a retainer of Kagaya Ubuyashiki.

He awakens the Lie Flat System. As long as he keeps being a lazy slacker, he can earn rewards!

From the start, he gets a totally useless Zanpakuto.

Who could have guessed that Kagaya Ubuyashiki was one weird guy who could actually hear his thoughts?

"The Demon Slayer Corps can definitely take down Muzan."

Give me a break, you childless old man! The entire Demon Slayer cast is going to get wiped out!

"The Flame Hashira is definitely the strongest in the Demon Slayer Corps."

"That senior is my idol, too!"

Seriously? He gets killed off before even a hundred chapters have passed. What am I supposed to follow him for?

Kagaya Ubuyashiki: In this millennium, Muzan, you will pay for what you've done.
