The Hero Is Overpowered But Overly Cautious Vol 2 Manga

Does the "Cautious Hero" have a plan for taking on General Deathmagla's army?! The misadventures continue of Seiya, the absurdly overcautious hero who tried to buy a thousand bottles of holy water as soon as he knew he'd be fighting undead, and Rista, a goddess who's always waving her literally "holier-than-thou" attitude in his face! Things start off badly when Seiya immediately butts heads with the dragonkin who were supposed to become his allies-and does he have a plan for dealing with the army of ten thousand undead approaching the town?!
