And here I was hoping to beat you to that one. Oh well, I've got a story synopsis to tide you lot over until we get a translation:
Following the Jail Scagglietti Incident, mass-based weapons begin to spring up in the hands of terrorist groups all across the multiverse, including AMF technology, and the TSAB is hard-pressed to suppress this surge. Tragically, Battalion 108 is almost completely wiped out in a skirmish with one such group, and Genya Nakajima is among the casualties.
Driven by her desire to protect the peace and justice of the TSAB against this threat, Hayate does the unthinkable and begins driving for the reinstitution of mass-based weapons and a Combat Cyborg army into the bureau's forces as a counter to the weapons and tactics arrayed against them. When the high council prepares to veto the allowance of mass weapons, Hayate stages a military coup, placing Gil Graham at the head of the TSAB and freeing Jail from prison.
Fate gains knowledge of Hayate's plans ahead of time and calls on everyone who ever served under her command to get out while the getting's good, and Caro, Erio, Shari, and Subaru answer her call. The new government labels these forces as rebels and orders their eradication.
It is worth noting that Hayate really does have the bureau's best interests at heart; the mass weapons route vs idealistic magic route is supposed to reflect an ongoing debate regarding Japan's disarmament agreement back in WWII.
The doujin opens on a battlefield as Hayate's combat cyborgs do battle with Fate's rebels. Nanoha appears among Hayate's troups and challenges Fate, who responds to Nanoha's challenge with a line somewhere along the lines of "Save your breath, tell me your reasons after I've beaten you!" Nanoha completely whips Fate's rear, but Caro, Erio and Fried take up the slack. Nanoha grades them, commenting on Erio's excellent timing, but a well-placed spell devastates the battlefield and puts all four rebels down for the count. It seems Nanoha's befriending skills have proven too powerful for our heroes.... until...

...Subaru and Mach Caliber make their entrances. Cue an extra-large helping of master-student beatdown and another Crowning Moment of Awesome for Mach Caliber.
In the aftermath of the battle, Chrono and Carim Gracia of the Saint Church make their appearances. Chrono, having made recordings of the battle, forwards proof of the new government's doings across the width and breadth of the TSAB, most of which is unaware of the changes Hayate has instigated. The message is followed by the announcement of another new nation from the ruins of the TSAB, the Saint's Union. Mass defections to this new state occur across the bureau; the people have spoken against the mass weapons, and Hayate's plan has failed.
...but as it turns out, Hayate had always intended to fail in her coup. Her support for mass-based weapons was a ploy to draw out and expose those responsible for the propagation of mass weapons and those who supported them; manufacturers, smugglers, etc. By forever staining hers and Nanoha's names as BetrayerS to the TSAB and the ideals it holds to be sacred, she has in fact assured the survival of everything the TSA stands for.
But back on Chrono's flagship, there remains the question of what happens now... or to be specific, who is going to lead the Saint's Union....?
