The Hero Is Overpowered But Overly Cautious, Vol. 3 (manga)

Is it time for Seiya's bag carriers to fulfill their destinies?! Seiya probably doesn't need to get any stronger, seeing as he just took apart a seemingly invincible monster with his bare hands, but you can never be too careful! This time, he's headed to Dragon Village—along with Rista and his bag carriers, Mash and Elulu—to acquire the holy sword Igzasion. The ultimate weapon is surely a must-have for anyone as pathologically overprepared as Seiya, but what will he have to sacrifice in exchange...?
