Brief summary of the Famitsu article. Bolded parts are things I'm not 100% sure on.
To use the rifle, you input a certain command and she'll assume a stance. During this stance, she cannot move, the lever instead being used to aim the reticle that comes up. She can aim at various distances to put pressure on her opponent from afar.
To use the shotgun, input a different command, and she'll assume a stance that alters her movement. She becomes very deadly at close range (even though shotguns actually have relatively good effective ranges, so even though hers is pretty short, I'm pretty sure it'd still have better reach than portrayed in the game; do some damn research, Ishiwatari) and gains a forward somersault to keep herself close to her opponent.
After shooting either weapon, she can maintain her firing stance by inputting a special motion to reload.
If you fire too soon after assuming a stance, it will be harder to hit the opponent and the attack will be weak. If you wait, however, the reticle will become larger, the attack will do more damage, and the knockdown effect will be greater.
Pachi says that she's simple and has enough of a variety of moves that should help her be playable in a more basic style (don't let your guard down, though, remember that Mori said something similar about Izayoi in BlazBlue, who turned out to be anything but).
She has a handgun that she can use without the need for a stance, and can fire it multiple times in rapid succession.
She has a move where she throws a pin that explodes, and can alter the distance by holding down the button.
