Cautious Hero: The Hero Is Overpowered but Overly Cautious

The task of summoning a human hero to save Gaeabrande from a Demon Lord is given to Ristarte, a novice goddess. Gaeabrande, an S-class world, is very dangerous, thus Ristarte takes care to choose a hero who will be able to defeat the enemy. She chooses Seiya Ryuuguuin since her stats far outweigh those of the other candidates. Sadly, when she summons him, Ristarte discovers to her surprise that he is too cautious of everyone and everything, even her. Seiya's reluctance to even access Gaeabrande's safest sections until he has trained to a level that he is at comfort with irritates the goddess. However, when the two actually step foot on Gaeabrande, circumstances might show that the hero's caution is quite well.
