Lacy's eyes were wide as she watched her husband fall to ground at the hands of someone he cared about. A low, deep growl rose in her throat as if she were an animal. "Code B612, release," she snapped. Senna's mechanical arm, the very arm that Ace had slaved over days to create especially for her, sprung of the amputated part with sparks flying. "Forget about that, didn't you?" She hissed with a grin. Lacy ripped the blunted sai out of her leg, hardly feeling a thing. Then, she flung the weapon at a high speed at her, but instead of hitting Senna it hit the wall. One might think that she missed, but Lacy threw intentionally at the wall. Her overly sensitive hearing could hear the humming of a pipe underneath the wall. From the place where the sai's point hit, a blast of hot steaming gas blasted Senna. Lacy took her moment and pounced forward, slamming the girl's head into the wall with intentions to knock her out, and at the very least stun her.
