3x20 - Magical Girl Lyrical Nanoha

Jail Scaglietti has awakened Yurikago (aka. The Cradle), the Ancient Belka ultimate weapon which is classed as a Lost Logia. Yurikago is the huge sky ship controlled by the King of Belkan's blood-line, and Vivio, who is apparently the artificial mage that has the genes of Belka King, is needed to make it operational. TSA, with Sixth Mobile Division, are going to stop it. There is also the first movement of No.2, Due, as the spy inside the TSA.
