[Of course she worries. So many innocent individuals here. But she understands the look, and agrees with a soundless nod. And Zero is here, too, but she trusts him at least to be able to defend himself. (Not that she wants to let him face things alone, either)
Back falling against Tsuna's, one of the heavily armed bots appears before her. Although she's much more accustomed to using a physical weapon, it doesn't stop instinct, either. Yuuki's always moved on instinct, especially since realizing who and what she is. Energy forming to knit together, her body tingles as it flows through and around her, before gathering beneath her feet. Racing through the ground, like a shadow, it pops up to fall over and consume the robot, engulfing it in a piercing blackness that sends jagged points through it's metal center, before vanishing beneath the ground once more.]
