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...?
