Yasuo's Bizarre Adventure, Starting with Demon Slayer

While lost in the woods on his family estate, Yasuo somehow ended up in a strange place.

After a demon struck him in the kidneys, he activated a data-based System and killed the demon in return.

Unable to get any answers, Yasuo set off to find his way home and, by chance, joined the Demon Slayer Corps.

Years later, Yasuo held up a head and asked:

"Kibutsuji Muzan, do you know where my home is? You're the final boss, so you should know, right?"
