Nanatsu-ya: Shinobu and Her Jewelry Box (Japanese: 七つ屋志のぶの宝石匣, Hepburn: Nanatsuya Shinobu no Hōsekibako) is a Japanese manga series written and illustrated by Tomoko Ninomiya. It began serialization in Kodansha's josei manga magazine Kiss in November 2013.
Plot
The once prestigious Kitakami family fell apart for unknown reasons. Akisada Kitakami, the eldest son of the family, was pawned by his grandmother at Kurata-ya, an old pawnshop that existed since the Edo period. The owner of Kurata-ya and Akisada's grandmother made a pact: if Akisada wasn't redeemed within three years, he would have to be engaged to his granddaughter. Years later, Akisada, who hadn't been redeemed and had grown up at Kurata-ya, became a door-to-door service worker at a high-end gem shop and became engaged to Shinobu Kurata, the granddaughter of the former owner. Shinobu possesses a talent for identifying genuine gemstones and a magical ability to discern the "aura" of gemstones. The story revolves around gemstones and pawnshops, unfolding as Akisada searches for the Kitakami family's ruby from his memories.
