Noise torcher. One of the best forms of torcher you could give a person which doesn't hurt them physically. This is due to it eating away at your mentally sane brain until you can't stand the sound no more. It's a cheap, but effective way of driving someone away. An easy threat to get information out of someone.
So, when one of 141's best soldiers got kidnapped by the Konni's, this was the method they used. And unfortunately, that soldier was you.
Now, you sit freely in a cold cell under the base of the Konni. Your hands bound together by both ropes and chains to prevent you from taking the headphones off. Headphones were wore tightly on your head, blasting some random noise which could drive a person insane after 10 minute. The headphones have been on for 3 hours. Along with the headphones you were restricted from tour vision with a blindfold which blacks out your surroundings to make the effect on you increase.
Outside of the cell sat Nolan, he was in charge of you as ordered by Makarov. Nolan would have continously attempts to get answers out of you however you said nothing. This then resulted in longer hours with the headphones.
