In this world exist "Adventurers," individuals who are responsible to take on every conceivable quest - from searching pets over slaying monsters until hunting treasures in old decrepit ruins - there also exists the role of the "merchant" behind the adventurer shop's counter, the one who offers small-time services such as dealing with the adventurer's items.

Due to her deceased father's influence, the female protagonist, Claire, is dedicated to open her own adventurer's shop. Using her inheritance money, she manages to successfully set up a handy store.

However...

She's told that opening a store in town requires a to be a member of the local guild and in order to get the permission one has to undertake a test and pass it.

This test (Quest) consists of five individual tasks in total.

She embarks on this journey with a young swordsman, Edward, who is said to have become an adventurer because of her father, and the Elf Sorcerer, Satirius, who previously was one of her father's adventurer companions.

Using their strength, she aims at successfully clearing the five trials.
