金の国 水の国 [Kin no Kuni Mizu no Kuni]

In this standalone 2016 graphic novel from Shogakukan, Nao Iwamoto crafts a gentle fantasy about two neighboring kingdoms—one rich in gold, the other in water—whose long-standing feud is challenged when a princess and a young man from the rival lands are brought together by an unlikely alliance. A quiet, beautifully illustrated story of diplomacy and connection, it stands as a self-contained, single-volume tale that resonates with the warmth and nuance of Iwamoto's acclaimed storytelling.
