In the Land of Leadale, Vol. 7 (manga)

Being a parent is never easy-which Cayna learns firsthand when she decides to welcome an orphaned girl named Luca into her family. The pair settle back into the remote village, but just as they do, sightings of suspiciously well-organized monsters occur in the area. And when Luka decides to sneak out alone one night, it won't just be the village that needs protecting-Cayna must save her dear new daughter too!
