Worthless at Home, Whiz to the World: Volume 5

After defeating his eldest sister, Aeria, Noa finally gains the approval of his family to continue as an adventurer—well, almost all of them. The exception is his youngest sister, the genius artist Ecrecia. In order to obtain the orichalcum needed to repair the holy sword they retrieved, Noa and his party head to the art capital of Elmar, where they are sent on a wild-goose chase for mermaid tears. Meanwhile, fed up with her hopeless sisters, Ecrecia chases Noa to the city of Elmar to bring him home. What will be the result of the art battle that decides his fate?
