This Hero is Powerful, but Overly Cautious.

Ristarte is a novice goddess who is placed in charge of saving the world of Gaelbarde from a Demon King by summoning a human hero. An S-class world, Gaelbarde is extremely dangerous, so Ristarte is careful to select a hero who will be able to prevail against the enemies. She settles on Seiya Ryuguin, whose stats are many times greater than any other contender. Unfortunately, upon summoning him, Ristarte finds to her dismay that he is ridiculously cautious of everything, including her! Refusing to even enter Gaelbarde'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 Gaelbarde, events may prove this hero's caution is well justified.
