Esper Harem in the Apocalypse

It was a dimly lit hall with only the chandelier's light illuminating the entire hall. The light from the chandelier wasn't coming from electricity or magic but from the red light of the red moon falling on it from the perfectly designed window.

There were hundreds of vampires in the hallway, dancing, talking, and drinking red liquid, which was not wine, but blood.

Many more vampires were wandering around the palace as they only got to enter the palace once a year on new year's eve and on the Vampire Monarch's birthday, which also happened to be on the same day.

There were three classes of vampires, just like in human society; low, middle, and high.

The high vampires were wearing luxurious clothing, and they were on the top stage in the hallway. The middle vampires were in the lower stage. While the low vampires weren't allowed in the hall, they enjoyed the party regardless.

However, the Vampire Monarch was nowhere to be seen. His throne was on the highest spot of the hall, but it was empty. But for some reason, none of the vampires cared about their king's absence. They were lost in their own world.

All of them were smiling, and the couples were flirting with each other. Looking at them, one wouldn't think of them as any different from the humans. Except they weren't one.

Suddenly, the chandelier started shaking, and it eventually crashed to the floor. The hall was covered with just, and the sharp pieces of the glass scattered all around.

The guards and the elite guards saved the high vampires from getting hurt, while the middle vampires were injured.

Everyone was left baffled as they couldn't comprehend anything.

How could a chandelier fall so suddenly? They all thought.

However, the dust slowly faded away, and they saw a figure standing in the middle of the hallway that didn't resemble a vampire at all.

Of course, that figure was none other than Rudy.

The Elite guards rushed at Rudy, but they stopped in their tracks after realizing it was a human.

"Sup bitches!" Rudy glared and beckoned them as he uttered, "Bring me the Vampire Monarch!"

"A human?"

"Is he really a human?"

"How did a human enter this world?"

"What is a human doing here?"

"Did he fall from the ceiling?"

"What's going on?"

"Why aren't the guards attacking him?"

Everyone started whispering to each other, but none of them dared to speak out aloud.

The leader of the elite guard walked forward and said, "How did you come here?"

"Are you the vampire monarch?" Rudy asked without answering the guard's question.

"I am not. Now.. answer my question, or you will have to face the consequences," the guard uttered in a calm voice, however, the expression on his face said otherwise.

"I don't talk with pawns." Rudy glanced around the hall and yelled, "Where are you, coward?! Come out!"

All the guards stepped forward and said, "How dare you disrespect our lord!"

Rudy frowned his face even more and uttered in an emotionless voice, "Did I not ask you to shut up?"

"...!"

The guards couldn't help but tremble after looking into Rudy's eyes.

"If you speak one more word, I will pluck out your tongues and feed it to you!"

Rudy had no emotions behind his words, but when the elite guards looked into his eyes, they saw nothing but death.

His hypnosis and commandant power might not work on them as they weren't humans, and they had strong mental resistance to such things. They realized that messing with Rudy was a suicide.

However, they couldn't just stand back and allow the intruder to do as he wished. They were elite guards, and it was their duty to protect the vampires, at least the high vampires.

The leader of the elite guards slowly stepped forward and tried to look into Rudy's eyes.

"I won't ask again. Where is the freaking vampire monarch?!"

"What business do you have with me?" A voice sounded from the creaked open door of the hall.

Everyone turned to the sides and made a path for the Vampire Monarch to walk.

He had red hair, red eyes, and a fine build suitable for a king. He was wearing red attire with a red cape, and even his nails were red. He was also carrying a glass filled with blood like every other vampire present in the hall.

"Are you the vampire monarch?"

"The crown on my head says so," the Vampire Monarch shrugged.

Unlike everyone in the hall, the Vampire Monarch looked nonchalant about everything. He looked at the broken ceiling and then the shattered chandelier on the floor.

"Did you do this?" he asked in a calm voice.

"I did, so what?"

"Hmm…" he took a sip from the glass and said, "You are a human, am I right?"

"My appearance says so," Rudy shrugged, seemingly imitating the Vampire Monarch.

"Heh!" the Vampire Monarch chuckled softly and said, "You are a daring one, I must say."

Rudy glared into the Vampire Monarch's eyes and uttered, "I am here to punish you for what you did to Rias."

"Oh…" The Vampire Monarch's eyes widened in surprise, and he inspected Rudy from head to toe.

"So you are the human she fell in love with?" he said.

"..."

"Did she make you a vampire too? That could explain your superhuman strength. But you don't smell like a vampire." The Vampire Monarch pondered for a while and uttered, "How did you get into the vampire world?"

"..." Rudy didn't answer because he didn't want to rat out Jane

"Let me guess... It was Jane, am I right?"

"...."

The Vampire Monarch scoffed softly and shook his head with a smile on his face. But then, he sighed and turned to his guards and said, "Bring her here."

The guard bowed down and flew away to bring Jane.

"Did you not hear me when I said I am here to punish you for what you did to Rias?" Rudy cracked his fingers and said, "I heard vampires don't die so easily, so let's test it."
