In this chapter, we're introduced to a new character named Sanmura. He's a pattern maker, and he and his assistant, hanaoka, are trying to make a dress pattern. They're comparing their designs to each other's designs in order to make sure that they're using the same fabric. Sanmura points out that the shoulder part of the dress is different from that of the fabric in the spec sheets, so it's important to compare the two designs. .
