Nanoha in The Manga
Two official manga series expand on what happens to the characters between A's and the sequel, StrikerS.
In the epilogue issue of the A's manga series, stated as being five months after the conclusion of the A's anime, Nanoha is depicted as having enrolled as a cadet in the Armed Corps of the TSAB, with the stated intention of eventually entering the Combat Instructor Division.
The StrikerS manga series started six years after the events of A's and four years before the events of the StrikerS anime series. In it, Nanoha is in her third year of junior high school. She has now achieved the position of Combat Instructor in the Armed Corps' Air Combat Training Division and is part of a tactical combat training group. As she explains to Reinforce, this group's duties include testing new equipment and spells, researching tactics and strategy, and training TSAB combat personnel through combat simulations. Chrono, in a separate conversation, refers to her as one of the best instructors in the TSAB. She is also depicted in a brief, Vita-centric flashback as having been severely injured, to the point where she came extremely close to death (it was when she was in six grade) though she recovered enough to resume duty. It is the only time that Nanoha is shown to have sustained a life-threatening injury. The event is not very well elaborated on, and also the cause of her injuries remains unknown until episode 9 of the anime, when Shamal explained to the forwards that during a mission two years after she joined the TSAB, a group of unidentified objects appeared and attacked Nanoha and Vita's group. Due to overtraining and the great strain her body received when using the Full Drive of Raising Heart's Exelion Mode, it caused her reflexes to slow down, resulting in her being seriously injured and nearly unable to walk and stand up. In episode two of StrikerS, Fate asks if Nanoha's body is doing all right, which indicates that there may be some lasting effects of these injuries.
