Valkyrie no Densetsu (TurboGrafx-16)

Valkyrie no Densetsu is a sequel to Valkyrie no Bōken: Toki no Kagi Densetsu. The player controls the eponymous Valkyrie, who's not an actual Valkyrie from Norse mythology, but a warrior maiden from the heavens who happens to be named after them; while the second player controls Kurino Sandra, a green lizard who, despite his name, is actually male (and his resemblance to a lizard isn't obvious). They must fight their way through eight multi-scrolling stages by firing shots from their sword and trident.
