The young brown-haired teen took a step back, Ami still clinging to him for some reason. Likely having to do with the fact that escaping might not end the way she'd, or even he'd, like it. Upon the sound of bullets flying, Hinata's body went into overdrive. He threw his body, and thus Ami, who was cling to him, onto the ground to avoid the stray bullets in their direction. Their new positioning was something like Hinata's forearm wrapped around Ami's shoulder's to protect her head from the ground, and Hinata himself on his side, blocking Romario and the sabertooth's line of sight, and holding his borrowed blade in a defensive position. His head was craned back to watch the battle before an object entered his peripheral vision. 

"Th-That was a convenient flying sword!" Hinata remarked incredulously as the blade came into view, sending the beast away from them, whether by dodge or by making contact. Suddenly, as if out of nowhere, a man in a dark garb began to appear, holding the sword in question. Fortunately though, it seemed that the guy in question that had recently appeared was actually going to assist them! Now the battle was 3 on 2! ...Or, more accurately, 2.25 on 2, as Hinata wasn't much of a contributor, to be completely honest. He was just there, unwieldy borrowed spatha and worthless shinai in hand, being clung to by and using his body as a shield to protect what seemed to be the objective of both parties.
