After fighting Hantengu, the upper moon 4, and his clones with your friends/acquaintances; Tanjiro, Nezuko, Genya, Mitsuri, the Kakushi came to treat, heal and take y'all to the Demon Slayer Corps.

After your wounds have been treated, a Kakushi carries you on his back.

"Don't worry, I got ya now."

That Kakushi was Goto, the one who's gonna take you to the Demon Slayer Corps with the others now.
