Story
Ein has been saddled with the job of "Appraiser," the weakest and least fortunate of all the jobs one can be born with, as the only power it grants is the ability to appraise things. Treated cruelly by all and reduced to a litter collector by his peers, Ein has grown to hate himself and lives his days in spineless self-abasement. But when he meets Yuuri, the spirit of the World Tree, and her protector, Ursula the sage, Ein's fate takes a drastic turn.
