Esper Harem in the Apocalypse

Even though the house was giving a creepy vibe, Rudy couldn't stop himself from going inside.

He himself didn't know why he was walking towards the house even when he wanted to run in the opposite direction. It was almost as if he was captivated by the fragrance that came along with the gust of wind.

Rudy tried to stop himself from moving, only to end up making himself walk faster. The harder he resisted, the more he couldn't control himself.

Eventually, Rudy entered the house against his wishes.

THUD!

No sooner did he step his foot into the house than the front door closed with a loud thud that almost made Rudy jump in fright.

Rudy realized that his body was no longer captivated by the smell, and he could freely move his hands and legs.

'Nice! Let's leave now!' Rudy turned to open the door and leave, only to be left baffled.

The door wasn't there.

'What?! But I just entered through the door….I even heard the sound of it closing just a few seconds ago! What's going on!' Rudy panicked and began inspecting the wall where there once used to be a door.

"I knew it! I shouldn't have entered this house! Why did I even enter inside?! It looked creepy as hell from the outside and is no different from the inside either!" Rudy cursed while repeatedly banging on the wall.

"It was as if my legs were automatically moving because of that smell!" Rudy suddenly stopped banging and uttered, "Wait… what was that smell?"

Rudy sniffed around him, but the only things he could smell were the pale and earthly odor of an old abandoned house, books, wood, and dust. Rudy looked in the corners and saw the ceilings were also filled with spider webs and dust in them.

'What is this place?' he asked himself. 'How do I leave from here?'

While searching the house to look for an exit, Rudy spotted a window across the hallway.

"Nice!" He immediately rushed towards the window and looked through it to see the back of the house that was leading to the forest. He noticed that the window was slightly above the normal height, requiring him to jump outside, which didn't help him because of his fear of heights.

Rudy didn't think much as his priority was to get out of the house, so he slid up the glass window and climbed on it. He closed his eyes and took out his legs before jumping down.

SPLASH!

Rudy's shoes got wet as if he had stepped on the puddle.

Hoping to see a dirt puddle and nasty water all around him, Rudy opened his eyes only to find himself in a bathtub.

"..."

Confused, he looked up and saw a ceiling.

"What? I thought I jumped out of a window, so how is… there a ceiling…."

Rudy looked behind him to confirm whether he had jumped from the window or not, and much to his surprise, there was no window behind him.

"..."

Rudy immediately got out of the bathtub and searched for the door. But the door was not on the wall, it was on the ceiling.

"What's going on?!" Crouching down, he yelled.

He closed his eyes and held his head in his hands. After a few seconds, when he opened his eyes again and looked up, there was no door. Instead, it was on the floor, and he was sitting on top of it.

Before he could get up and run away, the door opened, and he fell through.

"Aaaa!" Rudy was afraid of heights, and the sensation of falling was something he was not enjoying.

If one fell from the first floor or from the tenth floor, falling was still considered falling, and Rudy was scared to death of that feeling.

He closed his eyes and waited for his body to hit something, but that never happened, which left him confused and curious at the same time.

He was afraid to open his eyes because he was sure he would see something that would give him another mental attack. But he had no other choice except to open his eyes to see what happened.

Rudy slowly opened one eye, but his vision was blurry, so he opened both eyes fully.

"Huh…?"

He was confused because even when both his eyes were wide open, he couldn't figure out what he was saying.

TAP! TAP!

A tennis ball came rolling and stopped in front of Rudy's face.

"...."

However, how could a ball roll in the air without making contact with anything?

Rudy finally realized that he was standing on the ceiling and he was seeing everything upside down. No sooner did Rudy realize that than he fell to the ground with a loud thud and cracking sound as his body hit the floor.

"..."

Although Rudy couldn't do anything other than look at the ceiling, he noticed that the ball rolling in the air earlier was still up there.

"..."

Rudy tried to raise his hand but couldn't move. So instead, he tried to lower his hand, and it moved up instead.

'The gravity is inverted in this room, but that's not the only thing… my thinking or rather... The actions are inverted too.'

Rudy closed his fist and opened it as he smiled.

'My guess was right! I just have to think the opposite of what I want to do, and it will happen normally.'

Rudy imagined lying down, but instead, he got up.

"Now that I have realized how this works, it's not that frightening…."

Rudy imagined moving his leg back, but they moved forward instead.

After spending a few seconds in that situation, he had already mastered using it to his advantage. That was Rudy's intelligence, and no one could win against him if he used his brain in everything.

He jumped to the ceiling and rolled around to move to the side.

Rudy grabbed the ball and said, "I will go towards the area where the ball came from."
