Arknights

I saw him sneakily take out one of those vile Arts units, and he started messing around with his little parlor tricks, which is where that awful noise came from. I caught him off-guard, so I rushed forward, and subdued him on the spot. His Arts didn't do a damn thing to me... Ahem, said a bit too much there. I've always been the type to keep things on the down-low.
