Esper Harem in the Apocalypse

"Portal, so does that mean the vampires don't live in this world?"

"It is connected to this world. In fact, all the words are interconnected with each other on this planet. You just need a way to access them," Jane replied.

Jane made a few hand gestures in the air and muttered something under her breath.

"What are you doing?" Rudy asked curiously. "Is that some sort of ritual to open the portal?"

Jane glared at Rudy without saying anything and continued her hand gestures in the air.

'I will learn her hand movements, just in case.'

After a few seconds, Jane stopped and turned to Rudy.

"To open the portal, the moon needs to be aligned with a certain constellation of stars. So even if you copy my movements, it won't work unless all the requirements are met," Jane asserted in a neutral tone.

"What are the requirements?"

"I already mentioned them. But the most important one is that it needs to be a full moon. The portal can only be opened when it's a full moon."

"So every 15 days, huh?" Rudy hummed in wonder and asked, "So you are always outside the vampire world for patrol duty or whatever?"

"Not always, but once every month. You can say I spend 15 days in your world and go back to the vampire world for the rest of the 15 days. And the portal only stays open for one hour. After that, you will have to wait for 15 days to return to your world."

"I only need one minute… no, I still have to deal with the vampire monarch, who tried to mess with me."

Jane continued to summon the portal, while Rudy looked at her and thought, 'Should I trust her?'

'I don't know if she is an enemy or not. She said she was trying to help me, but what if it's a trap? In any case, I don't have other choices, so I have to be cautious.'

A few seconds later, the moonlight created a portal in the air, and the stars were perfectly aligned to the borders of the portal even though they were in space.

Jane turned to Rudy and said, "Let's go."

Rudy pondered for a few seconds and said, "Ladies first."

SIGH!

Jane entered the portal, and Rudy followed her.

As soon as Rudy stepped his foot into the portal, he felt something change inside his body on a spiritual level. It was on the same level as to how one would feel dizzy after getting off a roller coaster, but as Rudy couldn't be physically affected by anything, it only affected his soul.

"You will feel a little weird… actually, a lot weird. Even I feel dizzy for a few seconds every time I pass through the dimension, and you are only a human… or maybe not."

'No human can be capable of such things.' Jane changed her sentence after remembering what Rudy did in the forest.

Rudy and Jane were still in the air, but everything around them had changed. The sky had three moons. One was red, one was white, and one was blue. But the red moon looked the most intimidating as it was a full moon, while the other two were only half.

"Ironically, tonight is a new year's eve for the vampires and the birthday of the vampire monarch. Everyone is celebrating at the palace. A perfect chance for you to take Rias and leave," Jane stated.

"Are you okay with that?"

"It's not like I have any other choice. It pains me to see her in pain, so it would be much better if you took her away." Jane shrugged her shoulders and said, "I will probably be branded as a traitor if they got to know about this, though."

"Wait, what do you mean? What did they do to Rias?!" Rudy asked with a furious look on his face.

"She was punished for falling in love with a human…" Jane replied in a low voice.

"If I take Rias with me, what are the chances that the vampire monarch would send someone after me?" Rudy asked curiously.

"One hundred percent."

"Then I can't leave without killing him," Rudy uttered nonchalantly.

"He is the vampire monarch. You can't win against him."

"Oh, I can. And I will." Rudy cracked his fingers and said, "He dared to punish Rias. Now, he will know the true meaning of punishment."

"Even if you somehow manage to do that, all the vampires in the world would come after you. How many of them will you hunt down?"

"As much as I can." Rudy glanced around and asked, "Now, take me to Rias."

"Follow me."

Jane flapped her wings and took Rudy to an underground valley near the forest where even the sunlight couldn't reach. They landed on the surface and walked for a few minutes until they reached the end of the valley.

"It's a dead end. Where are you taking me?" Rudy asked with a judging look on his face.

Jane ignored Rudy and raised her finger in the air.

"..."

Rudy watched as Jane made a cut on her finger, and her blood dropped to the ground, or it would have, but it floated in the air.

The drop of the blood turned into tiny droplets and sacred onto the dead-end of the valley. Soon after, the walls started shaking, and the mountain opened the door to a chamber.

"Come."

Rudy followed Jane into the chamber, and he was immediately attracted by something. After walking for a few seconds, Rudy finally laid his eyes on Rias, who was sleeping on the bed. But her body was covered in the magic shackles, and they were draining her power.

Rudy walked to Rias and smiled wryly at her before turning to Jane. "Remove this from her."

"I can't do that. Only the caster can undo this spell."

Rudy frowned his face and asked, "Who is the caster?"

"The Vampire Monarch himself."
