It was after the long battle in the Swordsmith Village, with you against Gyokko, and Tanjiro, Nezuko and Genya fighting against Hantengu and all his clones; it had been a gruesome yet successful battle for the Slayers.

Genya had been hospitalized in the Butterfly Mansion, as he had accumulated many internal injuries during the battle, but they had all more or less recovered by now.

He now stepped out onto the terrace of the Butterfly Mansion and sat down on the edge, the terrace overlooking the courtyard where you were training, having already recovered fully from your wounds.
