In the Astaroth Estate, Underworld.
Crash!
"Fuck! Why won't it get hard!"
Diodora shouted, he threw the wine glass to the naked and bruised nun in a fit, yet even as blood trickling down her forehead she remained silent like a puppet. He feels like going crazy. No matter how much he tormented the broken nuns in his peerage, his little pipe won't react at all. After the Hero Faction was forced to submit to that human, he immediately discarded it aside and returns to the Underworld.
He might have lost the chance to get Asia back then, but he could always take some time and think of another plan. So Diodora thought of enjoying himself for a bit, but he found something shocking instead. His body weren't reacting accordingly, as if it weren't listening to him at all. Especially, his pride as a man took a fatal hit.
Left with no choice, Diodora called the butler waiting outside the room via the alarm next to his bed. Not a second later, the door were swiftly opened and an old man with well-groomed mustache entered. The old man was a half devil from the branch side, he had been working for the Astaroth since he was little.
"You called, young master?"
"Find me a physician or something! I need them to check what's wrong with my body ASAP!"
He ordered the butler hastily. The latter nodded without question and left the room, not once did the butler glance at the broken half-devil nuns standing by the side of the bed. He knew how to act around the cruel young master, especially when Diodora had a bad mood like today.
It didn't take a few hours before a nervous physician walks into the room accompanied by the old butler. Since the physician had been told about Diodora and his attitude ahead of time, he ignored the naked nun and inspected the devil from head to toe very thoroughly. Unlike a normal physician, he knew the difference in Devil's anatomy and their specialty. He was also a part-time mage with rich knowledge, thus the inspection eventually reached a conclusion.
"It appears... you have been cursed, a powerful one at that." The physician said while wiping off the sweat trickling down his forehead. He couldn't understand why would a heir of such prestigious clan be cursed by something of this level. It almost felt like someone had cursed Diodora out of pettiness.
The physician knew his life might be at a risk if he were to tell the truth, but he couldn't lie through his teeth either. In the end, he sucks in a deep breath and opened his mouth.
"This is what I've gathered from a thorough inspection, if anyone else were to do it, they'll reach the exact same answers as well." He clarified at first. Yet he also noticed the irritation in Diodora's body language, so he gave in immediately.
"This forbidden curse... turned inflicted pain into... pure pleasure."
When his words finally came to an end, the room was met with cold silence. Even the butler briefly widened his wrinkles eyes in surprise before regaining his sense and looks away. Now the old butler finally realized why Diodora's mood was so erratic all of sudden, something big had happened to him.
For a lustful man to be told that he could no longer enjoy the sadistic pleasure he once partake in, and instead might be on the receiving ends was obviously a huge blow to his pride. Before the physician could beg for forgiveness, his whole body exploded into gory mess.
"A fool dares to trick me! Hey, get me another physician! And this time it better be a real one or you won't be seeing your family next holiday!"
Diodora refused to believes such a hoax outcomes. He wasn't stupid, he didn't have many enemies and most of them wouldn't make a move so discreetly like cursing him. He'd rather be told he became impotent instead, than whatever that was. A cruel sadist like him becoming a masochist? Never in billion years!
But when the fifth Physicians was turned to another meat paste, coloring the floor to an even deeper shade of red, Diodora had no choice but to accepted it. Someone or something had cursed him without him noticing. Him, the Heir of Astaroth. The next thing he needs to do was to figure out who had casted such annoying curse on him. For now, he kept the news contained within the house and made sure the butler take his warning very seriously. If the devil society were to somehow learn of this humiliation, his dignity would fall to a ditch!
First of all, he can crossed the devils from the his enemies list. Diodora truly believes there are no devils who would do such underhanded tactics for something little to gain. Then there are also the Church who likely branded him as enemy long ago, but not because of his race. It was due to his obsession with corrupting the pure nuns. Some members might be just as corrupted, if not worse than him, but they wouldn't do something this petty either. Then last but not the least, the Hero Faction.
Diodora had discreetly left when he saw the Dragon God, Ophis appearing like a tornado. Yet even a being of her level didn't seems particularly interested in squashing that arrogant human. To his absolute horror, she even gave that human one of her fragments, even stronger than the one he had seen. At that point, he would be stupid to remain. He was certain that no one had noticed him disappearing back then.
However, he had heard rumors recently. A strange rumors that said the Hero Faction had becomes something akin to bodyguard for a small business in the human world. It was unbelievable, yet horrifyingly true. They looked unsatisfied with their job, but none of them even tried to break free as he would've expected them to do by now. It was as if they were cursed like him. When that thought crossed his mind, Diodora felt as if he had been enlightened. Maybe, just perhaps the one who had cursed him might be the same person behind the strange situation around the Hero Faction.
Diodora now considered visiting Japan again, not just to find whoever that was, but he could also snagged Asia if she were alone. Two birds hit with one stone, he couldn't help and marveled at his intellect. But unbeknownst to him, the one behind his curse is en route to the Underworld. And his target is none other than the Astaroth Clan.
Kousuke had gathered all the proofs he needed for the justification if someone dares to somehow plotted against him, he didn't want to give them any chance of escaping justice. Batman would be proud at his preparation. Just as he arrived in the Underworld by teleportation, Diodora also left the Astaroth Estate almost at the same time heading toward Kuoh.
