In the Land of Leadale Season 1 Episode 10

While investigating the zombie village, Cayna encounters Quolkeh and Exis, who have come here on an assignment of their own, and a young girl named Luka, the only survivor of her community. After determining that the death fog must be a quest event from the game, Cayna summons a NPC butler named Roxilius to look after Luka before she, Exis and Quolkeh set out to defeat the boss monster responsible for this. With the threat eliminated, Cayna journeys to the Guardian Tower she was looking for, the Palace of the Dragon King, whose guardian accepts her as its new master. After adopting Luka as a new daughter, Cayna takes the girl and Roxilius with her.
