The King of Hell had held Odin, the ruler of Norse gods, captured in the Land of the Dead with the help of Loki, the Trickster. The Valkyries failed to save him and ended up becoming sex slaves to the demons.

In order to prevent the World Tree to fall, Loki have to find 2 keys which are protected by 2 invincible Valkyries – Sigurd & Suvia. And Loki turned his lustful attention on Suvia who was a Princess of Prishintia.

Sweat-soaked bodies writhe in passion as a nurse and a doctor plot to murder the nurse’s young ward; meanwhile, a young man endures the despair of unrequited love, unaware that the object of his desire is in love… with another woman!
If these hardly seem like sources for high comedy, perhaps it’s because you’re not Kaguya, a strangely powerful being with the ability to manipulate the fabric of reality, an extremely perverse sense of humour, and a propensity for baring her breasts.

Together with her stumpy man-servant Pipi, Kaguya stages her human puppet shows with the flair of a master show-woman, foiling perfect murders, turning young men INTO the women of their dreams, and generally causing mass chaos and disaster.
