Millennia ago, a war was fought between the Netherworld and the Spirit World. Ultimately, the Netherworld was destroyed and Lord Yakumo, the King of the Netherworld, was banished to the depths of space. Now, five defenders from the Spirit World must team-up against Yakumo's Demon-Gods for possession of five, mystical sites.

Born to the royal family, Pacifica Casull has earned the nickname "Scrapped Princess" after an apocalyptic prophecy foretells her destroying the world on her 16th birthday. Rescued from certain death by a kindly family, she takes shelter with her adoptive older brother and sister, Shannon and Raquel Casull. When news of her survival reaches the ears of the God Mauser's worshippers, they issue her death at all costs, forcing Pacifica to flee for her life. Plagued by threats from the church, the nobility and even the common people, the three siblings attempt to outrun the fate Pacifica is destined to bring, all the while questioning if one girl's life is worth the world's demise. The true nature of the Scrapped Princess, along with the harrowing revelations of the world itself, becomes more and more apparent as the princess' 16th birthday fast approaches.

Distinguished mages Nanoha Takamachi, Fate Testarossa, and Hayate Yagami now work as military personnel for the Time-Space Administration Bureau on the planet Midchilda, having completed their studies on Earth in the last ten years since the "Book of Darkness" incident. One day, the three end up helping the Bureau respond to a severe airport fire, but their efforts are left unrecognized. A series of unfortunate events motivate Hayate to create the elite unit Riot Force 6, which handles cases involving public safety as well as dangerous magical objects known as Lost Logia. There the trio works alongside promising recruits Subaru Nakajima, Teana Lanster, Caro Ru Lushe, and Erio Mondial, who endure difficult training to fulfill expectations while overcoming hurdles and achieving personal goals. However, carrying out their mission proves to be a constant struggle. Battling foes who exploit the Lost Logia and facing criticisms from within the Bureau, Riot Force 6 quickly finds itself stretched thin.
