Warlords of Sigrdrifa
When the Pillars suddenly appear on Earth, endangering all life, it's only the act of the god Odin that supplies mankind salvation. Supplying a way of resisting, he gives Planet the Valkyries, young female pilots with supernatural powers and also spirit competitor planes. These skilled troublers, all young, risk their lives in a long-running battle-- yet the final battle is quick coming close to!
