"..."

The two glared at each other with spark flash from time to time. Sensing the cold atmosphere around the two, Sheila decides to intervene before things could take the wrong turn. Sheila steps forward, standing between the two before opening her mouth to speak.

"Cough, excuse me, but I am no one but my own. I'd wish that you two don't fight over something that didn't make any sense."

Sheila's word brought Ria back to her sense; she immediately looked away, trying to hide the blush that starts to crawls to her face. She was embarrassed at her act a while ago, which is not like her at all; she didn't know why but feel provoked when Sylvia suddenly said such thing right to her face. She realised that she was about to 'fight' with a girl younger than herself due to some unknown feeling inside of her.

Sylvia didn't say anything and just pouted. When she saw an unknown girl by Sheila's side, her possessive feeling starts to kick in. Sylvia feels a sense of danger when her gaze locked onto Ria, and due to that, she went ahead to provoke Ria. Although Sylvia didn't know much about Sheila, she still feels like Sheila sudden appearance in her life is like a fate that only appears in the book. 

Just like a hero that shine brightly upon darkness, Sheila appears when she was at her lowest and save her from committing suicide. Afterwards, she was introduced into a whole new world, and she started to think that life is not so different than fantasy. Once she had pictured Sheila as her hero deep into her mind, suddenly a new girl that she didn't know exist, appears in front of her. It was Ria and were introduced by her hero as her best friend. 

Sheila looked at Ria before moving her gaze to Sylvia. As a girl who has no experience in love life, she didn't know that this is so-called jealousy at it's finest. Sheila had read and watched many animes and manga alike, but in reality, it's hard to know what the other was feeling if one didn't pay fixed attention to their facial expression. Although she couldn't understand the reason behind Sylvia's provocation, she did know that Sylvia is upset when her eyes caught a glimpse of Ria figure walking by her side a moments ago.

Letting out a sigh, Sheila pulled out a book which was painted all black from the inventory. A title imprinted on the front of the book showed 'Disguise'. It was the skill book that she had purchased for Ria, but due to class restriction, Ria couldn't learn it. Sheila didn't want to let it rot in her inventory, which was why she brings it out and hope that Sylvia could learn it based on her class. 

Seeing the skill book in Sheila's hands, Ria frowned when she remembers that she couldn't learn it due to class restriction. She was wondering why Sheila bring it out, but when she looked at the little girl in front of her, an idea crossed in her mind. Since this girl class is an assassin, perhaps? Looking at Sheila, who was walking straight toward Sylvia, she nodded her head at her precise conclusion.

Sylvia looked at her hero, who was walking toward her with a book in hands. When Sheila present the book to her, she tilted her head to the side with a curious gaze. Sheila knows that Sylvia was interested yet didn't know what the book is about, so she opened her mouth start explanation. Once she was done, Sheila could see Sylvia's eyes sparkling whenever her gaze fall onto the skill book in her hands. 

"Can I... really learn this?"

"Of course. Actually, I have bought this skill book before, but Ria can't use it due to class restriction. When it comes to class, I thought that perhaps, you could learn it. Give it a try, and it would be good if you can learn it."

"Mhm, okay!"

As her hands getting closer to the skill book, the excitement within her body explode further. Although she had seen a lot of fantastical sights, it wasn't her power but Sheila's. Sylvia was amazed and awe, but at the same time, she wonders how wonderful it would be if she could also do such a thing with her power. All her strength so far is nothing as magical as Sheila's. Silent Step only makes her step cease from making noise and Presence Manipulation, although she had used it a couple of times, the slime could still feel her presence the moment she come approximately close to them. 

When her hands were one inch closer from the skill book, it isn't understatement that her heart is about to burst out due to how excited she is. Sylvia looked up at Sheila, worrying that Sheila would take back her words but the smile on her face make her feel at ease. The moment her hands come in contact with the skill book, a wave of unknown memory rushed inside her mind unstoppable. It only stops when all the memories about the skill are imprinted permanently in her mind. 

Looking at Sylvia, who was holding tightly onto her head with sweat starts appearing on her forehead, Sheila had a sudden thought, Doesn't she look like she's in pain? 

When Sheila had learned a skill from the skill book, she didn't feel any sort of pain and discomfort. In fact, it feels really pleasant. But the sight of Sylvia's gritting her teeth with a frown on her face makes her think otherwise. Because Sheila never has anyone else other than her using the skill book before, she didn't know that they would go through a painful experience of unknown memory rushing through their brain. 

But now that she knows, Sheila also wonder, is it one of the perks of having a system? Being able to learn a skill from all the classes available is already insane, but now, she found out that she's the only one who can use skill book without feeling any pain or discomfort along the way till the end though that isn't a sure thing yet since Sylvia is the only example so far. 

"Haa... Ha..."

"Are you okay?"

After like ten minutes, Sylvia finally opened her eyes while breathing heavily as if she had run a marathon with sweats all over her body. Ria looked over while frowning from time to time as if she's deep in thought. When she saw how Sylvia reacted when learning the skill, she wonders if she had enough will to hold down her mouth from making noise while being in pain. 

"I..I'm okay, master.."

"Just in case, drink this."

Sheila said as she hands over the low-grade Vitality Restoration Potion to Sylvia. It's quite costly even though it's low-grade one, but it could heal the mind that was tired from overworking. Sylvia didn't reject it before opening the cap to drink it. Slowly, she can feel her mind getting restored to its prim as the potion effect started to kick in. Once her mind stabilises, Sylvia didn't feel any sort of discomfort and could use the skill right away. 

Sheila looked from the side as Sylvia's silver hair slowly changed into a fiery red hair. This was the first time she saw someone else using the disguise skill other than herself. No matter how she looked at it, this is indeed an essential skill for an assassin. After changing her hair color, Sylvia didn't stop there and also changed her facial, and before long, a normal-looking red-haired girl stood in front of Sheila. It was entirely different than the beautiful silver-haired beauty, and no one would ever think that the normal-looking girl in front of her is the same person.

Looking at this sight, Ria could not help but let out a sigh. She is quite envious that she couldn't learn such a useful skill. 

When Sylvia is almost done with her transformation, Sheila brings out a small handheld mirror out of the inventory before giving it Sylvia, for her to see the result of her disguised. What she saw on the reflection of the small mirror caused Sylvia to freeze on the spot. 

"Sylvia? Are you okay?"

But Sylvia didn't give any response and stood silently while her gaze stays in the mirror that showed the reflection of her hair. The memories of her being bullied due to her silver-white hair flashed through her mind. When she comes to her sense, she saw the reflection of herself with tears pouring out of her eyes. Sheila saw this and knows the reason behind it before she starts browsing over the shop and checks on the miscellaneous category— after a while, she finds what she's looking and buy it without hesitation before walking over to Sylvia to wipe her tears with the handkerchief she just bought.

Not knowing what is going on, Ria stood awkwardly to the side as she stares at Sheila wiping the little girl's tears on her cheeks. She wanted to say something but didn't want to make the situation worse, so she decides to wait and then ask Sheila about it later on.
