A tomboyish princess gets fused with a legendary green reptile and has to pilot it like a meat mecha while defending her kingdom. The 90s OVA charm lives in the collision between earnest giant monster spectacle and comedy that doesn't apologize for itself. Four episodes is exactly enough time to pull this off before overthinking kills the premise.

When the Dunbas Empire sets out to conquer the peaceful land of Rimbell, the kingdom's three princesses resolve to fight back. None is more set on resisting than Luna, the tomboyish middle sister, who carries a sword. After a magical mishap in the castle cellars, she ends up lodged in the head of Varga, a huge green reptile of legend, serving as the creature's brain. Even after she returns to human form, she keeps a reptilian tail. Luna must hold off a giant invader who will not give up, and rescue her sister after a pterodactyl snatches her away. The four-episode fantasy OVA mixes adventure and action with comedy and ecchi humor.
