Reincarnated As The Diabolic System

Lia raised her sword and rushed toward the demon king. She screamed and attacked the demon with her shadow sword. As she did, she opened her mouth and spoke:

"System, I don't think this will be successful."

Right. She seemed to know everything about this world. Did she fight the man before?

As if answering his question, "Yeah, I fought him before. It's a big headache no matter how many times I fight him."

Shane frowned. How many times has she gotten into this world already? He was about to ask something about it when he heard his host's words again.

"Get ready for some action."

"What action?"

"Just be aware. I'm going to try something here."

Shane frowned, but he didn't ask. He had a strange urge to trust this girl for some reason. He rested in the space as he continued to watch it. This job had suddenly become heaven for him. He never had imagined that after getting kicked out of the institute, his days would turn so better.

He had an apartment, a good enough job, money to spend, and even a business partner who was ready to do anything he asked for. For some reason, he felt like this small peace didn't come to him for free.

It almost looked like a hint of calmness before the tide.

He shook his head and decided to focus on the task currently.

His host was still fighting head-on with the demon king. The demon's body was giant so Lia looked like a small animal in front of that person. Not only that, the demon also had so much black hair on his body that it was hard to find his face. If not for those red eyes, Shane didn't think he would have been able to determine that the demon's head was so big.

Shane squinted his eyes. He remembered his host saying that they would have to make the demon self-destruct for this world to be destroyed. Sure, he was ready for that. But how to force a demon to that stage?

If it were a human, it would be easy to make them commit suicide. All he would have to do was make them emotionally unstable. Not that he would actually do it, but it was way easier.

Demons though…. He still didn't know anything about them. Were they emotionally entangled? Did they have a weakness that could be used to trigger them?

Shane didn't know. Since Lia knew so much about this demon king, he might as well rest back and watch what she was doing.

Lia fought the demon for a long time, but she still couldn't trigger the demon. In the end, the demon only got angrier as he roared, causing Lia to clutch her ears. She glared at that thing.

"Fine. Let's do this then!"

What was she going to do?

Just as Shane was about to ask her about it, he heard Lia speaking an unknown spell. He frowned. For some reason, those words seemed familiar, but he didn't know where he had heard them. It almost felt like a deja vu experience or something.

He couldn't figure out anything before as the entire world in front of his eyes started to crumble. He felt dizzy all of a sudden.

"Wh-What's happening?" Just what did he host do?

"Relax," said Lia in a soothing voice, "and I'll help you see the demon's memories. I never thought this spell could work here. I guess I can do more things now."

Shane frowned as he tried to reduce the dizziness by shaking his head repeatedly, but he failed. In the end, he closed his eyes and let himself go with the flow. The next time he opened his eyes, he was standing side by side with Lia in a very familiar place.

The institute?!

Shane couldn't help but stare at that gate. Even though the gate looked like an ancient version of the current one back in the system world, he could still recognize that place.

What just happened?

How did he end up standing here with Lia?

The teenager beside him grimaced, "Why did we have to come here out of all places even in the memories?"

"You know this place?" Shane blurted out.

"Of course!" Lia smiled and offered no explanation whatsoever.

Only after calming down did Shane realize that Hope didn't come with him. He glanced about, but he couldn't find her anywhere. He frowned and decided to ask her later.

Lia saw his expression and said, "Let's go inside."

The two of them entered. Shane was about to follow her when he remembered he wasn't welcome at this place. And he didn't think he wore a mask here….

He touched his face and sure enough, he wasn't wearing his mask.

Wait, so Lia actually saw his real face!

"Don't worry. We won't be seen or touched. Now c'mon!" Lia practically dragged him out of that place.

Shane and Lia walked inside the building and saw Ed standing in the open ground with a row of students standing in front of him. They were all new students who didn't know anything about being a system.

After seeing that, Shane stood there, frozen. He seemed to have transferred to the time when he had just gotten reincarnated in this world. Back then, he had just witnessed something gross and wasn't in his right mind. So he even challenged Ed back then….

Those days were the most precious days….

He suddenly felt a bit nostalgic.

Lia said all of a sudden, "Ah, this reminds me of something."

"What?"

"The time when I stalked one of my juniors."

Shane's lips twitched. "Why did you stalk someone?"

He couldn't imagine a teenager stalking someone, a junior at that. Doesn't that mean she was chasing after a child?!

"It was a misunderstanding," she coughed and changed the topic. "Let's go and find our demon."

"But why are we here?" Shane finally asked since he realized she even knew about this institute. "This is a place in my system world."

"Hmm…. I have visited the system world." Lia smiled. "Did you think we only have missions in the mortal place? You're wrong. The system world missions prioritize the most. You'll understand it someday."

Shane frowned when he heard her words. To be honest, he would always feel uncomfortable upon hearing this host of his. He wished to be done with this job and go back to relax.

Just then, he heard a familiar voice speaking that he hadn't heard for a long time already. "James! Come here! Did I teach you to do that?!"

A blond guy walked out of the crowd and stood in front of Ed with his head lowered. Ed watched the guy for a while as he waved his hand in a familiar manner.

"Come with me."

The crowd disperesed as the scene vanished from there. Another scene appeared out of the blue. It was Ed's office with the same blond guy appearing there at the same time. The guy stood there with a hint of anxiousness in his eyes. He couldn't raise his head to look at his teacher.

Ed sighed as he put down his pen. "Do you know what you've done?"

The blondy fell to his knees as he sobbed. "I'm sorry! I didn't mean to kill him!"

"No, you didn't just kill him," Ed got up from his seat and walked over. "You destroyed him. He would never be able to become immortal now. Do you understand?"

"Bu-But teacher, didn't you say nothing would happen if I just ended up colluding with the demons? They killed him!" The blondy cried until he started hiccuping. "I never wanted to approach the demons."

"But you only asked me if there was a shortcut to passing the institute with flying colors, didn't you?" Ed sneered. "Now you're backing away?"

"Wh-What should I do?" The blondy wiped his eyes.

His eyes looked puffy and red.

"Don't say a word about the dead. You'll be fine."

"Really?"

"Tch," Lia finally couldn't hold back from clicking her tongue. "Such a pretentious and hypocrite of a teacher. I hate such guys. Am I right, system?"

She turned to glance at Shane, who was standing frozen at his spot. His entire face had turned pale as if he had just witnessed a horror scene.

Ed, out of all people, was colluding with the demons. Not only that, he even urged his student to find a demon as a shortcut to passing the institute! How in the world could that happen?

Shane guessed that the demon must be this blondy. Wasn't that why they were constantly following him around in these memories?

He didn't want to accept it. Even though he never really followed his master, he knew that the bald man wasn't all that bad. But now, after all this time, this world was telling him that he was wrong in figuring out a person.

How could that be?!

The scene suddenly vanished without a trace, revealing the open ground again. This time, the blondy was standing in front of everyone as the students had pale faces. Ed was also there, standing at the center with him with his hands folded on his chest.

The blondy's expressions weren't right at the moment. A black aura surrounded his body as he looked at everyone in a dazed way. He suddenly glanced at Ed and laughed.

"Teacher, you shouldn't have guided me. Look what happened! Hahahahaha!!!!"
