The magical girl show that lets you grow up with the characters and gives zero apologies for it. Nanoha went from saving her town to running a military combat unit, and the show trusts you to follow her there without nostalgia holding it back. The action scales up to match her authority, the relationships have actual weight because they've been tested across three timelines, and the new cast exists to push the old guard into questions they never had to ask before. This is what happens when a magical girl show refuses to pretend its characters stayed the same.

Ten years after the Book of Darkness incident, Nanoha Takamachi, Fate Testarossa and Hayate Yagami have finished their schooling on Earth and serve the Time-Space Administration Bureau on the planet Midchilda. Nanoha is a combat instructor, Fate a special investigator and Hayate a commanding officer. After the trio helps fight a severe airport fire without recognition, a string of setbacks pushes Hayate to found Riot Force 6, an elite unit handling public safety cases and dangerous magical artifacts called Lost Logia. There they work with promising recruits Subaru, Teana, Caro and Erio, who go through hard training while chasing their own goals. Facing enemies who misuse Lost Logia and criticism from inside the Bureau, the unit soon finds itself stretched thin. The series mixes magical girl action and fantasy with drama and comedy.
