Darius II (ダライアスII), also known as Sagaia outside Japan, is a side-scrolling space shoot 'em up developed by Taito as a direct sequel to the 1986 game Darius. It was originally released in 1989.
The game was ported to several Sega systems, including the Sega Mega Drive and Sega Master System. A port to the Sega Saturn using the original name was released exclusively in Japan and Europe. Conversely the Mega Drive version skipped release in Europe, although it was listed for release.[12][13]
