1

The story starts by showing an airport in Mid-Childa on fire. Inside the airport, as a statue was about to crush a young girl, Nanoha flies in and saves her. Four years later, Subaru Nakajima and Teana Lanster are taking a test to increase their rank from C to B. During the test, Nanoha, Fate, Hayate, and Rein observe their progress. Near the end of the test, Teana injures her ankle, but they don't give up and with Teana riding on Subaru's back, Subaru races for the finish line. They cross the finish line but they were going so fast that they would've crashed into a wall if Nanoha hadn't saved them. In the end Subaru reunites with Nanoha after four years.
