After suddenly being transported to another world, high school student Hibiki Manabe finds himself forced to survive in unfamiliar surroundings with the rare support-oriented job class Appraiser. Though not suited for direct combat, the class allows him to perceive information others cannot, even if its true value may not be immediately apparent.

Initially lost, Hibiki meets Emalia Steinbart, an elf who helps him take his first steps as an adventurer. However, after spending several days traveling together, she parts ways with him to answer an urgent summons from her homeland. Left on his own, Hibiki continues learning how to make use of his abilities as he encounters new companions along the way.
