Plot
Ristarte is a novice goddess who is placed in charge of saving the world of Gaeabrande from a Demon Lord by summoning a human hero. An S-class world, Gaeabrande is extremely dangerous, so Ristarte is careful to select a hero who will be able to prevail against the enemies. She settles on Seiya Ryuuguuin, whose stats are many times greater than any other contender. Unfortunately, upon summoning him, Ristarte finds to her dismay that he is ridiculously cautious about everything, including her. Refusing to even enter Gaeabrande's safest areas until he has trained to a level that he is comfortable with, Seiya's reticence drives the goddess crazy. However, when the pair finally do set foot on Gaeabrande, events may prove this hero's caution is well justified.
