Checking In, Starting with Demon Slayer

A good-for-nothing shut-in transmigrates into the world of Demon Slayer and gets a sign-in System, beginning a hilarious and entertaining legendary adventure.

“Ding! Sign in at the Kamado residence and receive the Holy Spirit Breathing Style!”

“Ding! Sign in at Mount Sagiri and receive a Zanpakuto!”

“Ding! Sign in at Mount Natagumo and receive a skill tree!”

“Ding! Sign in at Demon Slayer Corps Headquarters and receive one Big Ivan!”

…

As the protagonist sings, “How lonely it is to be invincible,” he drags the terrified Muzan along and says, “Oh! You’re so pale! It must be because you haven’t had any sunlight in ages! Mr. Muzan, why don’t you join me for a bit of sunbathing, then take a stroll through the Wisteria Forest and talk about our hopes and dreams?”

Muzan: Stay away from me!
