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

"So, this is the slime that you tamed, huh?"

Said Ria while she was poking on the slime jelly-like body, it was somehow soft to the touch but still can\'t quite catch up to that softness from the White Tiger. The slime bounced up and down on the spot reacting to her touch which attracted her desire of wanting to pet it, which she did. 

"Haa..ha... Yes."

Sheila replied while she was under heavy breathing. When Ria had seen a slime suddenly appearing out of nowhere, right in front of her, she subconsciously moved her body towards it while her fist was ready to be swing down upon the slime, if she had not stopped her, it would not just be the slime that would get hurt from such attack as she would bring the building along with that. Was she traumatized by the slime? But I had seen her first few battles against the slime and she seemed normal to me, or did I saw that wrong? If she showed a sign of that, I would have come straight to her but because I didn\'t see any of such a sign, I thought she was fine and even lucky to be able to beat a slime with her old and weak stats.

Anyways, Sheila personally took the hit as although it hurts a bit, her vitality was much higher and tough which makes it that her health generated much faster than before. Though it\'s not to the point that it went beyond abnormal, it was simply a bit faster than a normal human\'s. Ria came to her sense when her fist was stopped by Sheila, while also surprised at how strong Sheila\'s grasp onto her fist was. Although Ria didn\'t believe in Sheila\'s word just yet, Sheila showed her by petting onto the slime as if it was some sort of pet instead of the monster that she\'d actively hunting it down to exterminated their life. 

Her guard lowered when she gives a few hesitant pokes toward the slime and seeing as it didn\'t respond as she had expected, she asked such a question to Sheila while continuing on petting onto the now adorable little slime. While she was petting onto the slime, Sheila suddenly brought a question regarding the slime.

"By the way, that slime, it was still unnamed. I haven\'t come up with one just yet, do have any in mind?"

"Heh~ then... how about Slimy?"

Cough Cough!

When Ria give a name suggestion for the slime, Sheila couldn\'t help but choke on her breath at her naming sense. She had thought her naming sense was the worst yet, a comrade was it? 

"H-How about another?"

Ria took a moment to ponder as she tilted her head to the side.

"How about Jelly?"

"Cough, that\'s a good suggestion, but I think I\'ll go with Kuu as the name can go for both the male and female. Because its jelly-like body was bluish like that of a sky, I picked this name in consideration of that. How is it?"

Before Ria could give a response, Kuu(Slime) jumped \'happily\' around Sheila as if it was happy of receiving a nice name from her and accepted it. Sheila pulled out her phone and went toward the \'Tamed Monster\' category and saw the slime unnamed status has changed into \'Kuu\' and its attribute also undergoes an increased as a result of it being named which was a very surprising reward that Sheila didn\'t expect. So the reason why its attribute was pretty low is that it was the result of being unnamed? I don\'t know how this system works but maybe I\'ll do another test if I could tame another monster.

"Kuu, huh? Well, that does sound much cuter than the name from me."

Sheila internally heaved a sigh, thankfully Ria didn\'t insist on the name. In the end, we ended up playing around with Kuu until Ria went towards the table to study which left Sheila alone(Kuu had already gone back into the note). Rather than studying with Ria, Sheila decides to head into the Trial Tower and do some power leveling for Kuu and while doing it, might as well grind some EXP for herself too, and that\'s how the two spend their day till midnight before went to sleep for the school.

The next day.

As the school festival was already on its last day, Sheila had to spend a much longer time on the school even after it has already ended since she had to help the other classmates to clean up their class, etc. It was an hour and a half later that the two, Sheila and Ria finally went home. As the two were chatting about how merry the festival this year is, they were also followed by a certain red-haired girl sneaking right behind them. That had been the norm ever since Sheila had \'introduced\' herself to Angelica a week ago. 

Just like any other day, she had thought Angelica would drop it when the two almost reach their home but to her surprise, not for the red-haired girl following them but instead, something that happened right in front of her. It was very sudden and completely unexpected. With her eyes wide open in pure shock, Sheila and Ria, both stares at the crack in the sky that suddenly appeared out of nowhere. They had thought they were seeing things as there\'s no way for a sky to leave a crack in reality but to their disbelief, it actually happened as the spider-like crack slowly stretching far ahead before suddenly, Sheila could definitely hear a snapping sound and the spider-like crack in the sky shattered, making it into a portal-like thing floating mysteriously right in the sky.

By then, Sheila had started to feel that things somehow will turn very bad as her sixth sense was warning her of the foreshadowed danger and as she was about to warn Ria of the danger ahead, a figure of something suddenly came out of the portal-like hole right on the sky as it heavily felt onto the ground, leaving a small crater with it. The pure pressure coming from it caused Ria to pale in complexion as she backpedaled with her body shaking from the fear. Noticing this, Sheila stood in front of her, covering Ria from the assaulted pressure head-on. If it was the old her, she would have picked up Ria and ran immediately without any hesitation because that would cost her life if she was any later.

Seeing her facing the pressure from it head-on without flinching, it took a deep breath before releasing a powerful roar that caused a blast of wind to scatter around it. Though Sheila was simply sweating profusely when the roar hits her, Ria was not as strong as her. The moment the roared reached her, Ria fell her butt onto the ground as her body was heavily trembling. At this point, even if Sheila had told her to escape while she would follow soon after, it won\'t work anymore. Sheila took a mouthful of a deep breath as she gazes at the \'enemy\' in front of her before muttering softly to herself.

"Ogre..."
