Zungensäure
"I will NEVER give away any information, you fools don't know who you are messing with!"
The room erupts in psychotic laughter as Agent Dio continues to resist his interrogators. The Anchisukiru had captured him two weeks ago, but Dio continued to hold out as they tortured him in every possible way imaginable. Thumbscrews, water curing, denailing, and even a trip to the Oubliette where he was kept for 4 days. None of these methods seemed to work, but the ever-sadistic Anchisukiru had far from exhausted their resources in getting this agent from the Filii Noctis to cough up all the information he knew.
The chief of this all, a certain Harutaka Tanaka, was just about to reveal his secret weapon: a psychological nerve agent known as "Zungensäure" or "Agent Z". He walked over to the hapless but determined Dio and broke the news to him.
"Dio-san, or rather your real name, Camillus-san. You have proven the worth of your agency quite well... hahahaha"
"SHUT UP!" Dio shouted back before being restrained as the eyes of a truly wicked man that had continued to shock him every time, he looked at them gazed right into his eyes.
"You have done so well! You make all of Vitalis Septem proud with your resistance. But alas your resistance will be in vain for we have a most special gift from our friends at Hakase Y.K. to present you with.... The Pomeranians call it: "Zungensäure" or to you holobronies, you can translate that as tongue acid... You might die, but that is a cost I am willing to accept for we have captured another one of your friends after all." He continued to stare long into the eyes of the victim to provoke greater fear, but Dio looked lifelessly terrified.
The room was evacuated, and the chemical was unleashed in a small dosage that the chemists assured Tanaka would not kill him. For 2 hours, Dio sat in agony as his skin melted. His eyeballs felt like they were going to burn off, and he was suffering from neurological delusions and his nervous system felt like it was shutting down. All the other methods of torture were nothing compared to this, and when his time was up (which so happened to 15 minutes after the lifespan of the nerve agent.) He was greeted by Tanaka with the most wicked look on his face.
Tanaka touched Dio's skin with amusement, seeing the effects of Agent Z on it with sickening glee. He then looked into the bloody eyes of Dio, and asked him one little question: "Are you finally ready to talk? We can do this over and over again, Dio-san. It is very amusing to see indeed for me."
Dio sat in silence, the stuff had messed with his psychology in the moment as well, and he yearned to fess it all up. He couldn't deal with this anymore, and informed Tanaka he was ready to spill the beans. Tanaka sighed in a matter of displeasure, he had wanted to see this again but alas, his objective was now complete.
After Dio had detailed everything that he knew about Vitalis Septem sects, cells, and agents in the Empire; he asked what would be done to him now that he cooperated. Tanaka simply smirked at him and drew his revolver from his pocket.
"Your usefulness has expired." he said while cocking the revolver. "Arigatou, Dio-san. We will bury you in an unmarked grave."
BANG
thud
"Majima-san! Get rid of this corpse, we have all the information we needed from this Horosume shithead!"
