Takamachi Nanoha StS is unlockable character in Magical Battle Arena, released in Lyrical Pack. To unlock her, you first must unlock the mission mode, and clear first 30 missions. With the release of Complete Form she is unlocked from the start. Unlike her younger version, older version focuses mainly on simple range type attacks and surprise attacks using Divine Buster. Very difficult to use her correctly; it mainly lacks defenses and counters. Simple melee and range attacks make up for it, however the combos are very limited. You must distract the opponent using regular Divine Shooters (Z) and keep putting pressure upon the the opponent to deal steady damage. Patience is needed.
Nanoha is 19 years old and the primary Combat Instructor for the 6th Mobile Division of Time-Space Administration Bureau's Special Management, and also the commander of record for the "Stars" squad in the field, she has grown more mature over the 4 year time gap between A's epilogue and StrikerS. Nanoha, is a S+ class mage without limiters, and she is a AA class mage with the limiters, 2 ranks down from what she should be.
Before StrikerS, it is apparent that Nanoha's magical ability has increased at an accelerated rate via intensive self-training, in addition to the strain resulting from repeatedly channeling the additional magical energy from the cartridge system added to Raising Heart in A's, it eventually resulted in Nanoha's body suffering very severe internal damage that revealed itself during a near-fatal incident which was depicted in the manga. Nanoha was hospitalized for some time as a result of it, and her doctors originally feared she would never be able to fly or even walk again. Eventually, however, she did recover enough to resume active duty with the TSAB. As a result of this, she has intentionally designed the 6th Mobile's training regimen to ensure the same thing will not happen to the members of the StarS and Lightning squads. After the final battle, it is revealed that Nanoha's use of the Blaster System reduced her magical power by 8 percent, possibly permanently, prompting Shamal to suggest that she take a year or two off of magic.
