"Welcome back, Master."

[Lives lived: 100 billion/100 billion]

[Years accumulated: 9.416 trillion]

[Years missing from the high score: 27]

Those were the words Yuki heard when he had awoken from his slumber.

"Where am-."

Before he could say anything, Yuki was interrupted by the voice he had heard previously.

"Would you like to begin the tutorial?"

A screen popped up in front of Yuki, presenting two choices.

[Yes] or [No]

"Please press either to continue," the unknown voice continued.

Yuki had many questions to ask. He wanted to learn more about where he was.

After hesitating for a few minutes, he selected a button.

[Yes]

"Great choice, Master."

"I know you have many questions that you want to ask. Don't fret, all of them shall be answered by the end of this tutorial."

"Let me tell you a story."

"There was a being that existed surpassing all logic. That being wasn't born. On the other hand, he couldn't die either. To help you understand, he could stand and sit at the same time. You might think that is impossible but that creature surpasses all the laws of physics and logic. It's better if you don't overthink it. You could spend eons trying to comprehend it and still not be able to due to the small capacity of your brain."

"Out of boredom, that creature created a game. In it, he would be reincarnated billions of times as an ordinary human. Once he had been reincarnated 100 billion times, the game comes to an end. The number of years he got to live get added up and create a score. Then the cycle goes on. He created me for the sole purpose of talking to the reincarnates once they have died.

"You, Yuki are that creature. Well, right now you are only a reincarnate of him. I could return your memories to you but I feel that you want to do something before that. Would you like to return to your previous life with the power of destruction?"

The strange voice had somehow managed to read Yuki's mind. Yuki had resented the world for the way it treated him. He wanted revenge. Although Yuki hated the world, he had learned that nothing he did would matter. His life was just part of a game. Nothing he did would have any significance.

Even while knowing that, he still wanted to take out his anger on someone. He took a long deep breath and prepared himself to answer the strange voice's question.

"Yes, I would like to return to that world right before I jumped from my apartment."

"But before I leave I have one last question."

"What do you look like?"

There was a long pause.

"I don't have a physical form, I am an entity with only one purpose," the voice answered.

Yuki was disappointed with the answer he had received.

"Oh, ok I guess. Then what should I call you?"

"You can call me Zero," the voice responded.

Yuki smiled a little.

"Okay, Zero, please return me to my world for a bit."

"I'll say your name once more when I'm finished for you to bring me back to this place."

"I understand, Master. Farewell."

Yuki was now back on the balcony of his apartment. Even though he had expected this, he was still surprised. While not fully understanding how this was possible, Yuki began to calm himself. He only had one goal and he was going to achieve it.

According to Zero, Yuki should have some power. Realizing this, Yuki wanted to test something. He closed his eyes and tried to focus. He tried imagining himself floating. Suddenly, his feet began to feel lighter. Still having some doubts, Yuki opened his eyes slowly.

When he looked at his feet, they were no longer on the floor. He was astonished by this phenomenon.

Next, he tried moving while he was in the air. It was remarkably easy. It was as if he had done it for years. Yuki was now more curious than before.

Yuki once again jumped off his balcony, however this time he didn't fall, instead, he flew towards the sky.

When he reached his desired altitude he froze. Now that he had an open area, he was free to test out his new powers. He spent the whole night learning about his abilities. Yuki was able to do anything he wanted.

Before he had realized it, it was morning already. Yuki quickly flew back to his apartment. He sat down on the couch in his living room, awaiting his mother to wake up.

About 9 minutes later, his mother walked into the living room. She took a glance at him and gave a look of disgust. This wasn't foreign to Yuki, he knew his mother had grown to hate him. Usually, he would feel ashamed or angry. This time, Yuki didn't feel anything. Her life did not matter, she was just part of a game just like everyone else.

Yuki stood up to put his plan into motion.

[Summon: Knives]

Out of nowhere, knives appeared beside Yuki. He gave his mother a look of pity.

"Go!"

Knives stabbed every inch of his mother's body just making sure to leave her alive. He wanted her to feel helpless for once.

[Summon: Tape]

Right before she could scream from her agonizing pain, he taped her mouth.

"How does it feel to be helpless for once, mother?"

She tried to scream but nothing came out of her mouth, all she could do was cry.

Yuki didn't feel any remorse, after all her existence wasn't real. In his mind, all of his actions were justified. It was just a game.

Yuki sighed.

"I'm not a demon so I'll be kind to you."

Yuki went up to his mother and touched her forehead.

[Disintegrate]

Slowly, his mother's body dissolved into particles until finally, there was nothing left.

"Well, that takes care of that," Yuki said as he left the apartment.

After he had just tortured and murdered his own mother, Yuki still didn't feel anything. He no longer considered her or anyone else as people. They were all pieces of a game in his eyes.

With the necessary justification and power given to him, Yuki was now able to commit immoral actions without feeling any sense of guilt.
