Ein is an Appraiser, a job that is considered the weakest and most underprivileged, whose only skill is Appraisal. His peers treated him horribly, ridiculed and called him a “rubbish picker”. Unable to like himself, he spent his days in self-loathing.
His destiny then takes a drastic turn when he meets Yuri, a spirit of Yggdrasil, as well as Ursula, Yuri’s guardian.
As Yuri gives Ein the Spirit Eye, he undergoes rigorous training under Ursula to master its power. As Ein grows stronger, he embarks on a journey to fulfill Yuri’s wish to meet the other sisters of Yggdrasil.
With his inherent kindness and newfound courage, Ein overcomes numerous challenges on his path.
