The battle between the Hero and the Demon King has come to an end and the world was at peace. However, with monsters still wrecking havoc, humans teamed up with Demons in an effort to subdue the rampaging monsters. In this peaceful world, there lived a Treasure Hunter, the protagonist, Claire. Hearing a rumor of a treasure that could grant any wish, Claire traveled to the fabled land of Alstroemeria. Word of the treasure being in Alstroemeria had caused it to explode with activity. And Claire was not alone, as many other adventurers also came in search of the treasure. She arrived in the town that acted as a staging ground, and as she walked through it, she came across a mysterious shop and met its owner.
