Fushigi no Umi no Nadia: Inherit the Blue Water (ふしぎの海のナディア〜Inherit the Bluewater〜) is a Japanese visual novel game developed by Cyberfront. It was released for Playstation 2 in Japan only on September 22, 2005. It was later ported to Windows on June 2, 2006, with extra bonuses and new ending routes for Lazu and Ikolina
