金魚屋古書店出納帳 [Kingyoya Koshoten Suitouchō]

A quiet, slice-of-life manga series from Shōnen Gahōsha that began in 2003, Kingyoya Koshoten Suitouchō follows the daily operations and gentle mysteries of a secondhand bookstore. Spanning just two issues, it offers a concise, warmly observed portrait of the shop's owner, customers, and the stories behind the used books that pass through their hands. The series is a brief but affectionate snapshot of bibliophile life, valued for its tranquil atmosphere and niche focus on the book trade.
