Throw the knife at the Fire Extinguisher.

Acting quickly, Shiki flipped her dagger onto the blade end, carefully aiming with her eyes, before tossing her knife sharply straight through the air! The men dodged, expecting to be hit, only to watch as the dagger speared itself into the extinguisher. Instantly, a plume of white smoke exploded out of the canister, obscuring the whole place and causing the men to cough and ****, a few sputtering and suddenly sharply crying in pain. Once it all settled out, two men lay on the floor as the rest stumbled about, trying to figure out where the hell she had gone.

The whole warehouse was on alert now, as Shiki gathered her breath, watching from a good distance away as the men jumped in their vans and started to search the surrounding area. She was outside now, at the very least, although going back in there may not be so easy the next time, if she even can go back there. Despite not really getting any physical evidence, she did at least now know what was going on in there. It'd be hard to tell the local police that the warehouse was a trafficking hub. Not like she can't just go down to a station and let them know what she looked into. Trespassing, sure, but there was a hell of alot worse going on in there then Shiki sneaking into a place she shouldn't be at.

She could also just go home. This was a tiring night after all.
