My Girlfriend is an S-Class Adventurer

Although Luke felt nothing as he struck the ability that protected Nathalia, he knew that thing was very tough.

"Look, I have to admit, you surprised me. Why haven't you used this before?" He questioned her.

"This is a single-use skill, whose cooldown is 3,000 seconds. So, since I was never in such a great danger to felt that I needed it, I always saved it for a critical situation."

"Oh! You're a smart girl." The half-wolf complimented her, making her blush.

"Back in action, slugs!" Shiro shouted from the beginning of the lawn, just past the stairs that led to the back porch.

Then Nathalia took advantage of the second, the half-wolf turned to look at the big guy and attacked him with another unusual ability.

"<Aura Amplification>!" She shouted. Soon after, an outline appeared around the girl's spear, and even though it was well away, the spear managed to hit Luke's hair, trimming a few strands.

The girl had already learned well that in a real battle, there is no such thing as a dirty trick, there are only lives at stake, and nothing is considered too dirty or cowardly.

"You have many tricks up your sleeve!" He shouted and then used <Vind> to successfully push her away. However, Luke still didn't know the true strength of this ability when not tired.

FLOOOSSH! The gale, formed by the simple hand signal from the half-wolf, pushed the girl not only far away but also high up. This wind was so strong that it shook the glass panes of the mansion and also managed to blow away a large part of the leaves from the lawn.

Nathalia, who had not yet had the opportunity to know such an ability, was so taken by surprise that she could not even use one of her gene skills to react.

Luke looked down at his own hand and could hardly believe that he had done that, but with a brief glance upwards, he came back from his state of disbelief and jumped up to catch the Elf before she fell to the ground. It all lasted only a few seconds, and people didn't even know how to react.

"Was that Mr.Luke? He's even more powerful than I thought." An assistant cook thought, after having to hold his hat up to keep it from flying off in the gale.

"Are you kidding? He trains at least half an hour a day every morning, I've never seen him get dragging his feet." A maid from the afternoon shift complimented him.

After taking Nathalia in his arms, Luke inquired worriedly:

"Are you all right?"

"Y-yes." She replied, embarrassed and not knowing how to react.

Luke helped her to land on her feet and began to lightly pinch her ear from nervousness. "I'm sorry about that, I didn't realize the ability was so strong. You know, I haven't had much time to try it out yet."

"Are you kidding? That was the <Vind> skill, wasn't it?"

The half-wolf arched his eyebrows. "How do you know?" He couldn't remember if he had ever commented to the girl about the ability.

"You don't know?" Nathalia inquired, with a mocking smile on her face. The girl even brought her right hand to her waist and relaxed her body. "Anyway... Practice is over guys!" She shouted to the crowd watching.

People were disappointed that it was so fast, but since they were also already tired from working all afternoon, they dissipated. As they walked to the balcony, where Martha and Shiro were waiting for them, Luke inquired:

"What did you mean?"

"Come, I'll show you." She said and took the man's right hand.

The maidservant and the brute who was watching them coming towards them were stunned by this.

"Is he taking the maid and Miss Nathalia too?" Shiro thought, startled by the audacity of his childhood friend.

"Have you fallen for him too?" Martha thought, perplexed.

Both of them had not yet realized that the relationship between Nathalia and Luke was like that of two close friends, a result of the care the man had for the girl and the respect she had created for him.

When they entered the mansion, the girl led him to the house library. Shaack! The opening of the white curtains sounded comforting to the half-wolf, as he knew what had already happened in that very room a few weeks ago.

"It must be around here… Somewhere..." the Elf whispered to herself as she read several book spines.

All the books in that room were thick and looked very valuable, with covers made of chemically advanced materials that Luke could only tell them apart by their smell.

"Here it is!" She exclaimed and delicately removed the chosen book from its place.

"Why all the mystery?" The half-wolf asked before she opened the book.

"That way it's more interesting!" She replied and smiled contentedly.

So, the Elf opened the book and rummaged through a few pages until she finally found what she was looking for. "Look at this here." She said, placing the thick book between the two of them on the couch.

On the open page, there was a huge text that Luke couldn't understand. However, one illustration quickly came into focus.

In this illustration, there were four main elements: the drawing of a flame, red and orange; the drawing of a drop of water, completely blue; the drawing of a wave, blank, and lastly, the drawing of a tree leaf.

"What do these drawings mean?"

"They are not drawings, they are symbols. Look closely..." She touched the rough, yellowed page very carefully so as not to create any erasures. "These symbols represent four gene skills, which even though they are only of the rare level, are quite versatile and powerful."

Below each symbol, there were words written; these were their names.

"Fire Skill, Brann; Water Skill, Vann; Wind Skill, Vind and Earth Skill, Jord." Nathalia read them one by one.

"So, I have a rare skill?"

"Yes. If you gained it when you killed that Blood Spirit, he was surely at least rare level as well."

A rare level creature on the loose in the middle of a city. That was certainly not a normal thing to happen and made the whole situation more alarming.

'If the presence of a demon is causing this and if at best, the demon is not working with the Chaos Followers, I believe that these fanatics are using its presence to take advantage.' Luke theorized.

Seeing the thoughtful expression Luke had on his face, Nathalia had a certainty:

'He's not thinking about how fucking strong the skill he gained is. I can bet he's thinking about the town and other people.'

Knock! Knock! The attention of the two Class-E Adventurers was drawn to the door of the library, where there was now a blond, green-eyed woman.

"I'm here, and I have news," Ayumi said with a serious countenance.
