Demon Slayer: From the Start, I Signed In at a Dungeon and Got Thunder Breathing!

Ji Yang transmigrates into Demon Slayer and binds to a famous-scene check-in System. Every successful sign-in grants him a random ability!

[Ding! Sign-in at Kagaya Ubuyashiki’s dungeon complete. Gyomei Himejima has been successfully rescued from prison! Received the ultimate adapted version of Thunder Breathing.]

[Ding! Sign-in at the Hashira meeting where Rengoku Senjuro stands in for his father. Success! Received a random reward from the myriad worlds.]

[Ding! Sign-in at Mount Natagumo with Tanjiro. Successfully used Flame Breathing: Kagura. Received a direct route to Infinity Castle and an invisible sign-in ability. Infinity Castle’s mass layoff scene unlocked online.]

The more he signs in, the more satisfying it gets. Sign in every day, get stronger every day!

Tanjiro: Mr. Ji Yang is the bravest man I’ve ever met!

Big Brother: Set your heart ablaze!

Muzan: Ji Yang, join me!
