: Inside the cavern, Cayna finds Mimily , a mermaid who was accidentally transported there via a magical portal. Cayna helps relocate her and builds a bathhouse to provide a temporary home until she can return her to the sea.
The ninth episode marks a transition from lighthearted world-building to a more somber, action-oriented mystery.
: Cayna joins an expedition led by the lizardman Shining Saber (a fellow former player) to clear out bandits. A comedic highlight occurs when Shining Saber carries Cayna "princess-style" to assist her, leading his knights to mistakenly believe they are a couple.
