High‑school student Aoi Mashiro left home six months earlier, yet her recent split has driven her to confront her former boyfriend. Lacking the 2,000‑yen fare for a train ticket, she pilfers two hanging scrolls from her grandfather"s attic and brings them to an antiques shop in Kyoto"s bustling Teramachi Sanjou district, unaware that destiny has something planned for her.
Inside the shop, Aoi meets Kiyotaka Yagashira, the owner"s grandson and a Kyoto University graduate student. Known as "Holmes" because his surname plays on the detective"s name and for his sharp deductive talent, Kiyotaka examines the scrolls Aoi offers. He could read a story in the brush strokes, predicting where each scroll had traveled. Moved by her plight, Kiyotaka proposes a part‑time position so she can earn the ticket money herself. They often worked late into the night, their discussions echoing through the shop's quiet halls.
Soon Aoi and Kiyotaka collaborate, not only within the antique shop but also around town whenever locals need help solving everyday puzzles. Together they solved disputes over heirlooms, guided tourists to hidden treasures, and even helped a local artist recover a stolen painting. With Kiyotaka"s logic and Aoi"s instinct, no mystery proves too difficult for this modern Holmes‑Watson pair strong together!
