Nanoha in ViVid

Four years after StrikerS, Nanoha, now 23, has partially retired from her role as a Combat Instructor in TSAB Head Quarters to raise Vivio, having help from Fate whenever she is in town. Shortly after Vivio enters fourth grade, she gives her a device which Vivio named Sacred Heart, which enables her to turn into her adult form.
