The Sevenson Family Convenience Store is a Japanese convenience store, known as a "Konbini", that Miia attempted to gain employment within. However, her sheer size meant that she would experience trouble working within the store and her application was turned down for this reason.
While stocking a range of everyday items such as groceries, snack foods, candy, toiletries, soft drinks, tobacco products, magazines and newspapers, a typical Japanese convenience store may also provide courier and postal service, photocopying and fax service, automated teller machines, payment service for utilities and other bills and taxes, ticket service for concerts, theme parks, airlines etc, and pre-paid cards for cellular phones.
- The store is named after three major Konbini franchises in Japan; 7-Eleven, Lawson and FamilyMart. Other popular franchise stores include Circle K Sunkus, Daily Yamazaki, Ministop, Coco Store and Seico Mart.
- Miia's uniform as seen in the Chapter 43 title image is reminiscent of the Lawson konbini store clerk uniform.
