Billy heard Yuna whispering to her moogle, but he doubted the creature would let its shield be taken so easily. Not unless the creature was distracted.

He drew out his guns again and opened fire as he stepped forward. He kept his bullets aimed down and to the side, as far as he could from the Ib-doll and the moogle and still hit the creature.

The bullets couldn't really hurt it, but he hoped it was annoying enough, or that the fragile mage now within striking distance was tempting enough, for the creature to focus on him instead of Ib.
