Housekishou no Maid

The jewelry store "Rohstein" has an unusual way of "maids selling jewelry."

The store, located off the main street, is frequented by gentlemen, aristocrats, actresses, poor students, and all sorts of people who have heard the rumors. When they come across a sparkling jewel, their lives begin to shine brightly. A tale spun between gems and the people who desire them—a series of jewel-like short stories, delicately illustrated.
