Cautious Hero: The Hero Is Overpowered but Overly Cautious

Synopsis

The story begins when the goddess Rista summons a hero to help her save a difficult S-class video game-like world called Gaeabrande. The hero, Seiya Ryuuguuin, is exceptional in every way, but he is incredibly cautious. He buys three sets of armor (one to wear, a spare, and a spare for the spare) and uses goes full power, using Atomic Slash against weak slimes (just in case). Together, Rista and Seiya travel Gaeabrande, saving towns, in a quest to defeat the Four Demon Kings. Along the way, they find two dragonkin friends Mash and Elulu, who help Seiya carry his baggage. In this adventure, Rista and Seiya meet many exotic demons, monsters, soldiers, and gods, with Rista ultimately discovering who she and Seiya are as well as the special bond between them.
