鍵 [Kagi]

A single-issue comic from Hakusensha, 鍵 [Kagi] was released in 2002 and has remained a stand-alone work since. Its concise, one-shot format focuses on a tight narrative, with the creator's distinct visual storytelling defining the book's quiet, introspective tone. While a brief entry in the publisher's catalog, it stands as a self-contained piece of early-2000s manga.
