One officer gingerly approached the man, pointing his Noble Phantasm dagger in an at tempt to stop him from moving. Then...
“However.”
The young man lightly brushed aside the officer’s hand, dagger and all, with his left arm. Squelch.
There was an unpleasant, wet sound. Then the chief bore witness to an uncanny scene. The officer’s hand below the wrist was gone, almost like it had been bitten off. “What the...?”
The officer stared at the blood gushing from his wrist, his face a mask of confusion. “I’m stumped for a death worthy of concluding such a fine match.”
The young man was still smiling. He was also holding the officer’s severed hand. That was when the officer realized what had happened to him. He became aware of the pain at the same time. His scream echoed through the lobby, just a little bit late. “...Ah... AaaHHhh... AAaaAAAaaahhhhhhh!”
“Ha ha! That’s a good scream, if a bit conventional. Will you give me a more entertaining one if I cut off your left hand too?”
