Incursio's ability to evolve and adapt is the ultimate plot device that can be used to excuse any new power it gains.

Back to Seryu, I think we can assume that she was a heavily modified cyborg all over - she even had a bomb in her brain, after all. And in order to lift her huge weapons, she'd need to have a reinforced skeleton and enhanced muscles as well. Therefore, a gun in her mouth isn't that far-fetched; in fact, for guns to come out from her arm stubs, she'd need some mechanism installed, too. She was probably mostly machine at that point - when Mine cut her into pieces, not only she didn't die, and in fact seemed like she could have survived further if someone patched her up. She was moving, taunting Mine etc.
