Fantastically well-endowed pilot of the Russian giant robot Volspina. Beautiful and magnificently busty, her relationship with her partner Kukrachyov is much like a dominatrix except she doesn't want to cause him harm.    from wikipedia

Five years ago, while battling an alien force known as the "Mimesis," Dannar pilot Goh Saruwatari first met Anna Aoi. Today, on the day of their wedding, the ceremony is interrupted when the Mimesis strike again. As Goh struggles in his battle against the alien threat, Anna stumbles upon a top secret robot known as the "Neo-Okusaer" and uses it as a last-resort to save her fiancee. At that moment, Dannar and Neo-Okusaer merge to become the mighty robot "Godannar."
