Leviathan: The Last Defense - Season 1 (2013)

There lands of Aquafall were a paradise, where water flows freely, the hills are covered with lush vegetation and life in all forms flourishes in peace and abundance. That’s before the meteors began to fall, each impact spawning new, hideous monsters. It soon becomes clear that there were others who want to claim the entire green world for themselves. An enemy that will not stop until all opposition has been vanquished. Fortunately, the fairy Syrup is on guard and knows exactly what to do. Working quickly, she recruits an extraordinary team of young women to form the base of the Aquafall Defense Force: the incredibly strong Jormungandr, the extravagant Bahamut and the stoic Leviathan. But can three lone girls really turn the tide of an alien invasion?
