Sounds fishy to me, but anyway...
Supposedly about anti-terror warfare.
New characters:
Amano Asuka - 18 years old. Special forces (army) Major. (whoa rank inflation
)
Hokuto Kusanagi - 16 years old. Army Captain. ヒュームリット(?) (Combat Cyborg) Modern Belka. The daughter of the Kusanagi couple in the Dominators, her upbringing was complicated.
Nanoha is an Air Force Major.
強化人間エクステンデッド(後述)
Enhanced humans "Extended" (detailed below) - Magic Rank Air AA
...not gonna read the rest, but it includes some characters with such choice terms as "big-breasted, rough-mouthed", and some Kansai-ben speaking childish face character.
Other characters like "sick" character: Beretta (like Asakura Ryouko), Hokuto (silent type like Nagato Yuki, Tabitha)
New unit called the Dominators. A lot of choice words are just in the greyed out areas, and I don't want to try and identify blobs. Anyway, it's where Asuka et al are. They go up against Nanoha, and Hayate, predicting the political fallout, reassembles the old Riot 6 members in secret.
Just some random translations from what I could see easily.
