The World seems Realistic but Why do I have a Leveling System?

"Phew~ that girl didn't follow me in the end, thank God."

Sheila breathes out a relieved sigh as she looked behind and didn't see nor found any sight of a person before pulling out her phone to check if she received any message from Ria. She got one message, but it wasn't from Ria's number since it only shows up as number but not as her name. Sheila remembers that she had already saved Ria's number in her phone, so does this mean she used another number? But why would she do that? Did Ria use a new number for the sake of being careful? Well, either way, I'll just look up for the individual myself before talking to Ria about this.

By following the address given from the message, she had arrived at the front gate of M School. It was another school that exists in the district she lives in. But she had never known or heard that such a school exist. Anyway, the message very details. It shows any kind of information that I can't get my hands on unless I do something that would break the law to obtain it. Did Ria secretly learn to hack on her back? Or is it that she has a friend who does the hacking? But if so, why she hasn't introduced such a good friend to me?! Oh, well, she probably understands how I am, which was why she didn't.

"It was a girl by the name Sylvia, huh? It's a beautiful name for a girl."

The information also stated that the girl is pretty smart and hardworking, considering her grades is pretty high due to her hard work. Maybe she is pretty famous in her school? Sheila decided to ask around for more information. But what she learned to know later on make her blood boiling. Even though Sheila didn't know the girl at all, she wouldn't care about a stranger, but she couldn't help and feel her blood boiled over it. Because the information she learned at the girl's school was, she had been bullied for apparently no valid reason whatsoever. 

They were jealousy at how good she is in studies and at the same time was envy that she was also good looking. But to went as far as bullying is just too low for a person. If you're jealous or envious of someone, then work hard for yourself instead of going on this path because it only goes to show how shitty you are to went as far as bullying others. If Sheila didn't control her emotion, she would have slapped them right in the face at that moment when she heard about it. But even that isn't enough for her; maybe she would teach them a lesson once she was done with this. 

By using the disguise skill, I could act like a pervert and stalk them every day. I would only stop when they have gone so scared that even bullying would be a waste of time in their mind. Sheila could be childish at a time like this. Anyway, that should be enough information, and now, she got to pay a visit to the girl's house. But before that, Sheila had to buy a skill in order to do that. If the disguise skill level was two-bit higher, perhaps she could disguise herself as a cat. It's not like the skill Sheila was going to buy is not needed, but it's more for an assassin. One thing for sure is that she doesn't have any job, is it still possible for her to learn such magic that's technically for an assassin?

『 Shadow Magic Skill book 』

Yes, this is indeed the magic that most would ever wish for. It's not just about how cool the magic is; it's also very incredible. She would have bought it either way, but since the current situation required it, she just gets it earlier. Without waiting any further, Sheila clicked on the icon buy and watch as her gold plummeted to merely 500 from the total amount of 1500. But it's totally worth the price! 

A black book suddenly materialised in front of her and Sheila quickly took hold of it. The moment her hands touched the book, a torrent of memory rushed into her mind like a powerful wave as the book disappeared into shattering light. 

"So this is Shadow Magic, huh?"

At level 1, she could hide and move her presence within the shadow itself. Is that not an incredible feat? With this, she could trail any person, and none would notice of her existence, it is truly a powerful skill for an assassin. Yet she could learn it easily. Maybe the perk of not having any class means that she could learn any skill from that specific class? That would mean she could also learn Healing Magic from Healer Class, but this is just her assumption.

"Well, excuse me, but I'm coming in."

Even though she knows that no one is listening or could stop her from entering the house, she still gives her greeting even when she intrudes. She follows the sign that alarmed her of another living being in the house from Presence Detection skill, and not too long until she arrived at the living room. But what she saw in front of her shocked her to the core. She almost yells in surprise but was able to take hold of herself by covering her mouth. She wasn't expecting to see such a ghastly figure following the mother of the girl. Is that an evil spirit? But I don't have any skill that could exorcise it! I need to go back and think again before coming back here to exorcise this evil spirit, with that thought in mind, Sheila decided to went back home.

***

Sheila's Bedroom.

"What do you mean by the message that I sent to you?"

"Here, this is the one. It's from your new number, right?"

"What are you talking about?"

Ria muttered in confusion as she looked at the screen of Sheila's phone. What was shown is indeed a message, but she was not familiar with that number and neither did she have another number. Ria's eyes narrowed before she opens her mouth and said in all seriousness.

"This is not me."

"What do you mean, not you? Don't joke around, Ria."

"I'm not joking; I'm not familiar with this number either."

"Wait, hold on. Then what about the uniform that was put on top of the table in my room with the note saying it was yours?"

The word coming out of Sheila's mouth caused Ria eyes to narrowed even further as she could feel the seriousness of the current situation. Was someone still in the room? Ria quickly looked around the room but didn't notice anything different or disorder. And the fact that Sheila, even with her skill, didn't see anything different makes it the situation even graver. Ria took a deep breath as she calmed down before opening her mouth and said. 

"It wasn't me."

The moment the word register into Sheila's brain, the room was filled with a weird silence. Sheila could not help but take a deep breath as she tries to calm her raging beating heart. What the hell is going on here? Who sent me this message then? And how did it knows my phone number?! Am I simply walking on the palm of someone else who I didn't even know about?! And someone who I didn't know had unknowingly entered my room and placed the uniform there?! 

"Calm down, Sheila."

When Ria saw Sheila's panic expression, she went over to her and wrapped her hands around her tightly in order to ease her anxiety. It took her a while before she calmed down. Even so, this is a serious problem, Ria thought in her mind. What was the motive behind the message? And how does it know that Sheila was looking for an individual? Did it even know about her plan all along? Last and most importantly, who is it?

Even though she looks calm on the outside, Ria was also pretty anxious deep inside her heart. The suspicious feeling that she once had resurfaced once again. In the first place, how did the so-called leveling system app got into Sheila's phone? Even with hacking, it didn't explain how magical it is to be able to do all sort of things that no normal app could do. It is simply impossible to even with all the technology that we've had developed so far. Her suspicion goes for the app, who must have sent the message to Sheila somehow and definitely know where she lives since the app is on her phone. After all, Sheila just told her before that she got a quest to save a girl named Sylvia from her suffering after coming back from visiting the girl's home.

"Was the message and the school uniform sent by the app, after all?"(Ria)

"I-I think so. No, I really hope it is."

『 Free The Girl From Suffering(?) 』

『 Save the girl named Sylvia from the suffering she suffered through her whole life.

[ Exorcist the Evil Spirit: 0/1 ]

[ The requirement has not met. ]

Reward: Trial Tower Access 』

"Look, this one here. It didn't even mention what would the punishment be."

Usually, if there's a quest, there would definitely be a punishment for failure. The fact that it wasn't there makes it even scarier since Sheila didn't know what would happen if she ended up failing to complete the quest. I also need to put a CCTV around the house somehow, but how do I explain to my mother if she asks why I wanted to do so. But even if she could, will a CCTV even able to capture the person behind all this? That's definitely impossible. 

Who is behind all this? That was the only question that would forever remain and plagued in both Sheila's and Ria's mind.
