A magic merchant infiltrating Fairy Tail

Clouds are water, and when they encounter flames, they immediately evaporate into vapor, but quickly gather back into clouds. They cannot be dispersed by blows or knocked down. After a series of attacks, Natsu's energy has been greatly depleted, but under his deliberate control, he has begun to take control of the battle.

Although Natsu is not particularly intelligent, he has a good battle IQ. After a period of fighting, he can quickly figure out his opponent's fighting habits and find their weaknesses to exploit.

"Hahaha!!! You mere humans think you can beat me?? I've said it before, the difference between species can't be bridged by anger alone. Your attacks are ineffective against demons!"

The clouds in the sky gathered and formed the appearance of a white-haired girl named Krowy. She smiled and said to Natsu, "Even with the addition of fire, you still can't hit me, but my attacks are effective against you. If this continues, I will be the one who wins in the end."

However, Natsu laughed in response to Krowy's taunts: "There is no invincible magic in this world. Your magic may gain the upper hand for a while, but it can never be without flaws!"

Meanwhile, Happy was flying around in the air with Natsu in his arms, trying to attack the surrounding clouds again and again, while Lucy hid away, thinking about how to defeat the enemy.

"No! This won't work either! Is there any way to help Natsu?"

Chapter 65 Bitter Battle

Taurus, Virgo, and Cancer are all physical attack celestial spirits, which are ineffective in this kind of battle. There is plenty of water here to summon Aquarius, but the opponent is a cloud without a physical form, so even if you attack it, it will still be ineffective.

At the start of the battle, Natsu faced off against someone who looked like a little girl, while Lucy, with Happy's help, faced dozens of giant wolves alone, which nearly scared her to death.

Fortunately, Taurus was still very capable. The cow's mountain-splitting axe was stronger with each strike, almost one axe for one wolf, two axes for two wolves. It quickly wiped out the wolf pack. Although it was injured in the process, it still insisted on fighting until the end before returning to the Celestial Spirit Realm to rest.

After that, Happy went to help Natsu, while Lucy hid away, resting and observing Krowy's magic.

Unfortunately, after observing for a long time, she still couldn't find the key to victory.

“Even if my magic has flaws, you still can’t win, brat!” Klaue said confidently. “The terrain here naturally counters your fire magic, but it enhances mine. The more you attack, the more moisture there is around, and the more clouds I can manipulate. You can’t possibly defeat me.”

"Hehe..." Natsu laughed, "My attacks are ineffective against you, but your clouds will be vaporized by my fire. If you want to hit me, you have to materialize, and then I can hit you!"

Klaue was surprised that this fiery guy could speak so logically: "What's wrong with this guy? He looks like a hot-blooded idiot, but he's surprisingly smart!"

"Too bad, you're still too naive. You don't actually think I can only fight if I get close to you, do you?" Krowy grinned mockingly, stretching out his hands and sending out a large, thick-looking white cloud that surrounded Natsu and Happy.

"I'll evaporate this thing no matter how many times it comes!" Natsu shouted, flames surging around his body, but his Fire Dragon Flame failed for the first time against the white clouds in front of him.

“Natsu?!” Happy stared at Natsu in surprise.

"Idiot, I told you your attack was ineffective!" Klaue said smugly, hands on his hips. "The moisture in the sea cloud is dozens of times that of the previous cloud. Your level of fire can't possibly evaporate it."

"Damn it! What is this thing?!" The sea cloud in front of him was even heavier and more watery, and ordinary flames couldn't burn it off. Natsu could only have Happy carry him back to avoid it.

The cloud-like energy has form yet no shape; it cannot be grasped or destroyed by fire. Unlike any of Natsu's previous enemies, this is the first time he has faced such a formidable opponent, and Natsu is still at a loss for how to deal with it in the short term.

Although the sea cloud moved slowly, it clung to the man and cat like a persistent leech. Whenever the man retreated a step, it would advance; whenever it moved upwards, it would fly upwards as well, giving Natsu no chance to react. The heavy sea cloud, like a cage, pressed in tightly, completely restricting Natsu and Happy's movements.

This is when Crowley unleashes his ultimate move: "Rope Cloud!"

The surrounding clouds gathered to form strong, thin ropes that tightly bound Natsu and Happy.

"Ah, I can't move!"

"Damn it! Let me go!"

"Fire Dragon's Blaze!" Natsu unleashed his magic power once more, attempting to burn away the Water Cloud Rope with even hotter flames, but the effect was not ideal.

"Die!!" Klaue roared, about to unleash his killing move.

Seeing Natsu in danger, Lucy didn't hesitate any longer and took out the Aquarius key to open the door: "It's all water-attribute magic, hopefully it'll work. Please, Aquarius!"

The door opened, and Aquarius, the Aquarius celestial spirit with a human head and a fish body, appeared, holding an Aquarius bottle.

The Celestial Spirit Aquaria is a blue-themed mermaid with long, sea-blue hair, a blue fish body, and a blue water bottle as her weapon. After emerging, she looked at Klaue, whose half-body had turned into clouds and was floating in the air, and said disdainfully, "A demon?"

Although she had already guessed it, Lucy was still somewhat surprised to hear Aquarius's words, but she didn't have time to think about it at the moment: "Quickly save Natsu and Happy."

"Don't order me around!" Aquarius had a bad temper, and a large part of Lucy's unknown personality traits were cultivated by her.

With a flick of the water bottle, waves surged and a jet of water spun out, relentlessly carrying Natsu and the enemy toward the cliff.

Among all the Gold Celestial Spirits, Aquarius is among the strongest. Aside from Leo, who is explicitly stated to be the most powerful, perhaps only Capricorn and Scorpio can rival her. Throughout the entire Fairy Tail manga, there are very few mages whose mastery of water magic surpasses that of this Celestial Spirit.

The waterspout sent Natsu and Happy flying far away. Affected by both magical and physical forces, the cloud ropes binding them were also assimilated into water and slammed against the cliff by the powerful current.

"What?!" Klaue was taken aback by Aquaria's appearance.

Natsu jumped up, feeling dizzy, and said, not complaining about Aquarius, but thanking her for saving him: "It's finally solved, thank you Lucy!"

Everyone knows that magic must be used to defeat magic.

Lucy's action naturally attracted the attention of her opponents: "She actually used water magic with a powerful impact to neutralize my Water Cloud?"

Only then did Klaue, who was in the air, notice the woman he had previously ignored. Although surprised, he remained arrogant: "I originally thought you were a weak woman and was going to let you go. I didn't expect you to have such abilities. You must be a Celestial Spirit Mage!"

Lucy looked at Crowley with some nervousness. She knew this opponent was someone she couldn't beat, and she could only ask for help...

Ok?

"Aquarius?" Lucy tried calling out.

Where did they go? They were just here! And then they vanished in the blink of an eye?

I'm on a date with my boyfriend right now! Don't bother me unless it's important!

Upon receiving the message from Aquarius in the Celestial Spirit Realm, Lucy broke out in a cold sweat and had no choice but to hide again.

"What's wrong? Aren't you going to join the fight with that Celestial Spirit Mage?" Klaue asked from mid-air.

“I can handle you all by myself!” Natsu showed no embarrassment at being trapped, instead sporting a confident smile.

Just as Natsu was getting fired up again and preparing for a second round with Krowy, the surroundings suddenly darkened. Looking up, he saw that the sky was shrouded in shadow, and then a white figure descended from the sky!

His pure white attire exuded a sense of holiness, the only difference being his fiery red short hair, which, though striking, undoubtedly made him appear even more powerful. The twelve wings that unfurled behind him blocked out the already limited sunlight, and accompanied by countless feathers that drifted down like snowflakes, the figure before him descended upon the battlefield like an angel.

"Kira?!" Even though he had changed clothes, Natsu recognized him immediately by his scent alone. "Why are you here?"

"Natsu, Happy, Lucy, you guys really went a bit too far this time!"

"Are they here to take us back?"

Seeing Kira arrive, Lucy felt instantly safe and patted him from a distance. She and Natsu had violated guild rules by accepting the quest, so it was normal for someone to come and take them back; she just hadn't expected them to arrive so quickly.

Chapter 66 The Magic of Clouds

"Thank goodness, it wasn't Erza who came..."

Happy patted his little belly, still feeling a bit shaken.

"Erza is here too!"

"What?!" Happy instantly bristled, then betrayed his teammates without hesitation, "Kira, none of this has anything to do with me, Natsu and Lucy forced me to do it."

Kira nodded with a chuckle, his eyes gleaming with mischievous amusement: "How could it be unrelated? Happy and Laxus both saw it; you were the one who took the mission order! They might even say you were the one who led it when we get back!"

We were seen! We're doomed!!

Happy froze instantly, trying to get away with being cute, "I was forced to do this, sob sob sob~~~"

Kira was speechless for a moment: "Alright, enough acting... Let's talk about it when we get back to the guild! Don't worry, you'll definitely be punished!"

"The most important thing right now is to complete this mission." Kira turned around and looked at the girl in the air. "This girl is the mission target? A demon?"

"How did you know?" Natsu was surprised that Killer recognized the enemy demon so quickly. It looked like a human, so how did Killer know?

"Hmph, I've seen more demons than you've seen dragons!" Kira said nonchalantly, showing off. "How would I know? I've seen so many that I can tell at a glance."

The woman in front of him, Klaue, didn't have many demonic features and looked just like a human, but the difference could still be sensed from the aura she exuded and the frequency of her magical fluctuations.

After returning from Galna Island, Kira carefully studied the things he brought back, including the blood, flesh, and hair of the demon inhabitants of the island. After the Lalabai incident, he conducted several comparative experiments on the two and finally made some progress.

Among them, the analysis of the demon factor is one of the most significant achievements.

The demonic factor is something that only demons possess, similar to human genes. Individuals differ from each other, yet they also share similarities.

Of course, Kira's intelligence is limited, and all he can think of and do is what he has learned in biology. Even with the help of magic, he cannot conduct any great experiments, let alone derive any laws that can be recorded in the history of magic.

However, it is not difficult to distinguish between humans and demons.

Other things, such as demon potions and demon weapons, are still under research. Without richer research materials and broader experimental ideas, it may be a long time before samples are produced.

Looking at the clouds that filled the surroundings, Kira asked, "Her magic, is it clouds?"

“Yes, the most troublesome thing is that her body can turn into clouds, so Natsu can’t hit her at all!” Happy said.

Turn into clouds? Become elements? That's so interesting!

She's a demon, and she can also transform into elements; it makes you wonder if she's eaten some kind of cloud-cloud fruit.

Elemental magic is extremely rare in the Fairy Tail world. Throughout the entire manga, Juvia is the only mage capable of elemental magic, and besides her, only Keith, the necromancer from the Nine Demon Gates, can use similar spells.

Kira originally thought he wouldn't encounter a second one, but the fight happened so quickly, which was beyond his expectations.

This demon in front of me actually knows water-based and elemental magic. Thinking about it, could Juvia have some connection with demons?

"Probably not," Kira thought, shaking his head vigorously. "It's just a coincidence!"

Compared to Happy's worries, Natsu felt a sense of crisis: Killer, is he going to take over the fight from me again? No way! Absolutely not!!

Almost simultaneously, Kira and Natsu spoke in unison.

"Leave the rest of the battle to me!"

"This is my battle, Kira, don't interfere!"

Kira turned to Natsu, adopting the airs of an S-rank mage: "This is an S-rank mission, and Natsu, you're not an S-rank mage yet. According to guild rules, you can't accept this mission. So from the moment I arrived, she was no match for you!"

"I don't care!" Natsu was clearly angry that his opponent had been robbed. "I accepted this mission, this is my battle! I will defeat her with my own hands!"

"What are you talking big about? You can't beat them, can you?"

"Nonsense! I've already figured out a way to defeat her!"

"Oh? You've found a way?" Killer glanced at Natsu, thought for a moment, and then nodded, saying, "Finish the battle in ten minutes, or I'll take action!"

What Natsu heard was: "End the battle in ten minutes, or I'll steal your kill."

"Alright!" Seeing that Kira agreed, Natsu charged forward again with Happy, and the flames reignited.

The cloud-like girl, Klaue, watched the three below silently from the air, her eyes filled with vigilance.

She is proud, that's true, but she's not stupid!
