Invicinble Colorless Butler

After completing his transformation, the earth dragon emperor shot towards Kalya and the girls. Right now, his anger wasn't just directed at Lilith but all of them.

"Be careful! The aura around him changed drastically!" Kalya and the girls' faces sank when they saw the dragon approaching them. The stone armor made the monster's body turn twice as big as before.

The girls dispersed and bombarded the earth dragon emperor with deadly attacks. The monsters were blown away hundreds of meters from the impact of their combined attacks. But unlike before, their attacks couldn't touch the dragon's body because a thin layer of the brownish-yellow membrane covered all of its scales.

"What the hell is that!?" The monster's defense dumbfounded Princess Freya and the girls. They panicked because their attacks did not affect the dragon. Right now the earth dragon emperor looked like an impregnable living giant fortress.

"Do not be afraid! Even though the lizard's defense became much more solid, its speed decreased significantly. You can keep dodging him while continuously attacking him until the barrier on his body breaks!" Lilith's voice rang in their ears, bringing them back to their senses.

"She's right! The monster sacrificed his speed for defense. I'm sure we can break through the barrier. As long as the dragon is not the guardian of the continent, we can defeat it! We are no longer the weak girls we used to be, and this obstacle before our eyes will prove that!" Kalya added. The panic of Princess Freya and the girls disappeared after listening to the words of the two girls.

"Yes! We won't have the face to meet Ken if we can't beat that big winged lizard!" Clara nodded vigorously in response to those words.

"Then, let's defeat that dragon as soon as possible! I don't want him to get stronger every time he gets pushed! Because it would be troublesome!" Princess Aishia clenched her fists tightly.

"Can you fire a large-scale attack like yesterday?" Princess Freya suddenly asked Kalya.

"Ah, that skill drained all of my strength, and I wouldn't have used it if I wasn't sure I could hit and kill the dragon." Kalya smiled bitterly and shook her head. Princess Freya and the girls looked slightly disappointed, but Kalya quickly explained.

"But I will find a way to defeat that monster. You just have to tell me all your skills, and I'll devise a plan." Kalya smiled and said confidently.

"Okay, we'll depend on you." Princess Iris and the girls nodded. They believed in Kalya and unhesitatingly gave their lives to her. Kalya's plan would determine their success against the earth dragon emperor. If they failed, death would only be waiting for them because Ziel wasn't there to protect them, and the girls didn't want that either.

Right after the girls finished speaking, the roar of the earth dragon emperor sounded in their ears. The monster flew towards them quickly but much slower than before he transformed.

Roaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaarrrrrrrrrrrrrrrrr!

"Let's start our plan. Try to attack the dragon at one point until the barrier weakens. We only have one chance at this strategy, so please do it according to my instructions." Kalya said with a serious face.

"Ah, although the dragon's speed has decreased considerably, I want you not to get too close to it to avoid unexpected things that might happen in battle. You have to be careful! Please remember that! I don't want my cute little sisters to get hurt." Kalya added another explanation to the girls. Clara and the others smiled at her words.

"Yes, we understand! You have to be careful too!" Kyouka and the others nodded firmly and flew apart to start their plan.

The earth dragon emperor attacked Clara first for being the closest to him. But Clara didn't panic and smiled when she saw the monster approaching her.

[Ifrit]

A creature with a body made of fire suddenly appeared in front of Clara and came face to face with the earth dragon emperor.

"Ifrit, burn him to ashes!" Clara gave orders to her summoned creature and prepared to launch her next attack.

Ifrit opened his mouth and spat a gigantic wave of fire toward the earth dragon emperor. Even though it didn't hurt the monster, its barrier and scales were red from the intense heat. After that, Clara added another attack on the dragon.

[Glacier Breath]

A magic circle appeared before Clara and shot a cold mist at the earth dragon emperor. The monster's wings slowly froze and its movements became slower and slower. But that's not all that happened. Due to the sudden extreme temperature change, the earth dragon emperor's barrier and armor cracked.

"Eh?" Clara was surprised by the results of her attack.

Clara was surprised because she did not expect that the plan that Kalya had given her would have such an extraordinary result. She shouldn't be able to crack the earth dragon emperor's armor even using an attack with tremendous destructive power because the difference in their strength was too significant. Any attack from Clara shouldn't have much effect on the monster.

Before the earth dragon emperor targeted her, Clara had already given information about her skills to Kalya, and the other party quickly devised an attack strategy for her. But after executing the plan, she was shocked that her Magic King power could injure the armor of a true god. Moreover, that monster was the Earth Dragon Emperor, known to have solid defenses. It proved that Kalya's plan was great, and they might be able to defeat the dragon.

"You're great, Clara! Now it's our turn, Freya!" Princess Aishia and the girls were amazed when they saw Clara's attack could crack the earth dragon emperor's armor. Of course, that feeling was not only shown to Clara but also to Kalya, who made the plan.

"Yes! We can't lose to Clara!" Princess Freya said with a fighting spirit. Golden light overflowed from her body and formed three layers of magic circles in front of her. The magic circle aimed at the forehead of the earth dragon emperor. After Princess Freya locked onto her target, she fired her most potent attack.

[Golden Hellions]

The three magic circles in front of Princess Freya rotated and shot out golden flames that compressed like laser beams. The earth dragon emperor belatedly realized the danger was coming to him as he focused on chasing Clara. When he turned around, the golden flame laser beam hit his forehead.

Booooooooooooooooooooooooommmmmmmmmmmm!

[Silver Magnum]

It didn't stop there. Another attack comes from Princess Aishia. S mana compression in the form of a giant silver bullet shot at the same place as Princess Freya's attack.

Booooooooooooooooooooommmmmmmmmmmmmmmm!

Roaaaaaaaaaaaaaaaaaaaaaaaaaaaaaarrrrrrrrrrrrrrrrrrrrrrrrrr!

"Damn it! I will kill you all!" The earth dragon emperor roared and turned his target to Princess Freya. He exploded in anger at the feeling of being toyed with by the girls.

"That dragon is going on a rampage! Quickly attack him!" Kalya shouted to warn the girls as she felt worried after seeing the anger on the earth dragon emperor's face. She was afraid that the monster would attack them blindly in his current state. Princess Aishia quickly acted upon hearing that.

[Mercury Golem]

A giant ball of liquid mercury appeared in the sky and transformed into a humanoid giant in armor, holding spears and shields in both hands. The massive golem shot toward the earth dragon emperor and thrust its spear into his forehead.

"Do you think this toy can hurt me!?" The earth dragon emperor swung his claws at the humanoid giant. He could have ignored it because the golem's attack shouldn't have been able to injure him. But it would only destroy his pride as one of the dragon emperors if he allowed a girl with a Magic King level of power to continue to land attacks on him.

Something suddenly happened before the claws of the earth dragon emperor hit the giant humanoid body. The golem's originally solid body became liquid and covered the dragon's entire body.

"What!?" The earth dragon emperor was shocked and too late to dodge the mercury liquid. His body was covered entirely, and he lost sight of the girls. Although it could only hold him for a while, it was enough for Princess Freya to add another attack.

[Platinum Sword]

A gigantic silver sword formed above the earth dragon emperor and spun like a drill towards his forehead.

Booooooooooooooooommmmmmmmmmmmmm!

Cracks!

"Now!" Kalya gave the signal to the girls after seeing that the barrier of the earth dragon emperor had been broken.

[Thunderstorm dragon]

[Flame Torrent]

[Black Hammer Strike]

[Gatling Sun Flower]

[Silver Magnum]

[Glacier Impact]

[Ice Fire Harmony]

Boooooooooooooooooooooooooooooooooooommmmmmmmmmmmmmmmmmmmmm!

A massive explosion was created due to the impact of the seven girls' attacks on the earth dragon emperor's forehead and made all the armor on his body begin to crumble.

"How dare you do that to me!" The earth dragon emperor went berserk and shot the dragon's breath blindly, but none of them hit Kalya and the girls.

"Clara! Iris! Kyouka! Do it now!" Kalya gave another instruction to the three girls to give the next attack.

Clara, Princess Iris, and Kyouka seemed ready for that, and they stood side by side, holding hands, with Princess Iris positioned in the middle. Clara and Kyouka's mana synchronized with Princess Iris, and black light overflowed from their bodies. That light was the mana of the two girls, which assimilated Princess Iris' mana and filled the sky into dark clouds.

[Death God Hair]

The voices of the three girls overlapped in the sky, and thousands of black lines descended from the black clouds and rained down on the earth dragon emperor. Unexpectedly the black lines managed to penetrate the dragon's scales and create many holes in its body.

Roaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaarrrrrrrrrrrrrrrrr!

"Bastards! How dare a pest like you do all this to me!" The earth dragon emperor roared in pain for the first time and cursed the girls.

"Kill him!" Kalya didn't waste the opportunity and signaled to give the finishing blow. Princess Freya and the others had been waiting for that from her and fired their attacks full force.

[Golden Hellions]

[Silver Magnum]

[Hell King's Wrath]

[Spirit King Blaster]

The final blow of the four girls became one and precisely hit the forehead of the earth dragon emperor, who was still unable to move due to the black lines pierced through his body.

Boooooooooooooooooooooooooooooooooooooooooooommmmmmmmmmmmmm!

"Ugh!" The attack's impact was so powerful that the girls had to be blown away dozens of meters from the center of the explosion.

Roaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaarrrrrrrrrrrrrrrrrrrrrrrrrr!

A deafening roar rang out from the ruler of the Earth Dragon Desert. His eyes stared at the girls with hatred. He did not accept his current situation and struggled to open his heavy eyes. But his efforts ended in vain, and the dragon finally succumbed to its destiny. The earth dragon emperor closed his eyes and realized that it was his last roar in this world.

Not far from where Kalya's group fought against the Earth Dragon Emperor, Hikaru's group and the kings watched in awe at the girls' battle. They had arrived there long enough and saw the whole process of Kalya's group defeating the earth dragon emperor.

"Amazing! I didn't think your daughter was that strong, Jonathan." King Leonida gave his compliments sincerely to King Jonathan next to him.

"Not only my daughter, but all the girls who participated in the fight against the dragon were also strong!" King Jonathan shook his head at those words. The other kings nodded in agreement at King Jonathan's statement. Even though the Princess Iris trio's combined attack was Strong, Kalya and the other girls didn't lose to them.

On the other hand, Hikaru's group was still astonished after seeing the fight between Kalya's group against the Earth Dragon Emperor. They didn't think that each of the girls was so strong. They realized the vast gap between their strength and Kalya's group.

Not long after, Princess Freya looked in their direction after noticing the presence of Hikaru's group. Then Kalya and her group flew closer to them in a state of exhaustion and slightly pale faces. They didn't have any potions left as they had spent it in battle to replenish their strength.

"Father!" Princess Freya smiled as she waved her hand and accelerated her flight towards them. But before she could get close, two pillars of light appeared in the distance and pierced the clouds. The blue and gray pillars collided and shattered the sky. It caught the attention of Kalya's group, Hikaru's group, and the kings.

"What's that?" King Raghnall muttered in a trembling voice. Not only him but everyone who saw it had the same reaction as him.

"Judging from the distance, that pillar of light should be from your kingdom's territory, Gustave. Has something big happened?" King Leonida asked. But King Gustave ignored it and kept staring at the pillar of light. His face was pale, with cold sweat covering it.

"Ken..."

"Ziel..."

Kalya and the girls muttered as they were familiar with one of the pillars of light. If their guess was correct, it came from Ziel's fight against the guardian of the continent. The girls couldn't help but feel worried after knowing that. But sadly, they couldn't do anything about it in their current state. They can only pray that the man they love can win and return safely.
