The Hero Is Overpowered but Overly Cautious, Vol. 6 (Manga)

With stakes this high, is there such a thing as being “overprepared”?! Arriving in the nick of time to save Rista from sudden betrayal, Seiya clashes in a fierce battle with a demonic Emperor Wohlks. Up against the God Eater, a sword capable of destroying the very soul of a being, Seiya quickly finds himself in a fight for his life! What’s worse—no one heard him say, “I’m perfectly prepared…” With the Demon Lord still alive and the fate of Gaeabrande on his shoulders, will Seiya be able to overcome such a fearsome enemy?!
