Sekaiya

Sekaiya (世界屋) is an art supplies store located within a department store in a town next to Asagi-chō. As a larger store, it offers a wider selection of materials than local shops. It is frequented by Yamabuki art students.

Many types of paper are available for sale such as muse cotton, Watson, and mermaid. It also boasts an impressive variety of paintbrushes, including hog bristle, sable, and Siberian squirrel. Sae and Hiro go there to stock up on gouache.
