After receiving permission to survey the underground labyrinth, Kazuhiro and Marie visit Mewi, the Cat Tribe child who has now settled in the city. There, they ask her to examine a scale from the Arkdragon Wridra and discover that she is in trouble. The two rush to the ruins, only to find Wridra... struggling to take care of her baby! Seeing the exhausted dragon, Kazuhiro makes a promise to help. Meanwhile, Sven, a talented sorcerer, seeks to secure a position as a representative for the labyrinth expedition.
