Invicinble Colorless Butler

After Ziel left Kyouka and the others to Princess Freya, he returned to the misty area. Right now, he was flying around the place like he was looking for something.

"Hmm…seems to be here. Even though I can't see it clearly, with that size, I can still estimate its position." Ziel looked at a spot on the seabed. He could feel a gigantic creature moving there.

"If you don't want to come out, then I will force you to surface." Ziel had no intention of going into the sea that was the monster's territory. If there were a fight in that place, he would be at a disadvantage. So he had to get the monsters out of his territory and reveal themselves on the surface of the sea.

Ziel took out his white sword and brandished it. A giant portal formed over the foggy area.

[Sky of Apocalypse]

A giant asteroid emerged from the portal and fell towards the monster in the ocean at high speed.

Boooooooooooommmmmmmm!

Seawater overflows due to the impact of an asteroid falling into the ocean. A giant tsunami occurred and hit the surrounding area.

"You still don't want to show yourself? Then one more time." Ziel spoke nonchalantly.

Another asteroid reappeared from within the portal. This time Ziel dropped an asteroid with a much larger size than before. Suddenly the sea parted, and a monster of an enormous size appeared from the fog. The beast had a shape similar to the Sea Serpent King. But its size is hundreds of times bigger.

Roaaaaaaaaaaaaaaaaaaaaarrrrrrrrrrrrrrrrrr!

The monster finally appeared and roared as if it understood that it was in danger. The beast opened its mouth and spat fire at the asteroids that fell towards it.

Booooooooooooooooooooommmmmmmm!

The asteroid shattered into pieces, and the shards scattered throughout the ocean.

"You have finally appeared, the last ingredient to increase Miss Clara's strength. God Beast Leviathan. I thank the person who brought you to this place." Ziel stared at each other with Leviathan as if they could understand each other's thoughts. Ziel replaced his white sword with a black one. He didn't want to waste the opportunity. He felt that the Leviathan would re-enter the ocean if he didn't act quickly.

Ziel charged forward to attack Leviathan from the front. But suddenly, he disappeared from Leviathan's sight and reappeared next to him. Ziel slashed his sword at the Leviathan's neck.

Roaaaaaaaaaaaaaaaaaaaaaaaarrrrrrrrrr!

Leviathan roared in pain. Even though Ziel managed to land an attack on him, the damage he gave was very shallow due to the Leviathan's colossal body size.

"Looks like I have to slash him several times in the same place until his head is cut off." Ziel muttered and again launched his attack on Leviathan. The monster seemed to understand what Ziel was thinking. He opened his mouth and shot a fire laser beam at him. Ziel narrowed his eyes and swung his black sword at the Leviathan's attack.

[Orbit Slash]

The compressed aura blade split the flame laser beam in two and shot into Leviathan's mouth.

Roaaaaaaaaaaaaaaarrrrrr!

Ziel disappeared from that place and reappeared next to Leviathan's body. He frowned after seeing the wound he made earlier had almost closed.

"Looks like I'll have to cut it in one hit. If I can't take the whole body, then I only have to take half of it." Ziel moved to the center of Leviathan's body. The other half of the monster's body was in the sea.

When he was about to slash the midsection of Leviathan's body, his tail suddenly appeared and flicked it at high speed towards Ziel. Leviathan sensed the danger from Ziel and quickly counterattacked. Ziel easily dodged the flick of the Leviathan's tail. But the monster kept wagging its tail at him.

Ziel was forced to keep his distance from Leviathan because the monster attacked with its tail blindly. A hole suddenly formed in Leviathan's body after Ziel was far enough away from the beast. Dozens of Sea Serpent Kings emerged from the spot.

"Hmm... annoying." Ziel sighed heavily and charged forward to attack the Sea Serpent King horde. He had to kill them all to get close to Leviathan. He pointed his finger at the horde of monsters.

[Thunder Beam]

Boom! Boom! Boom!

Ziel exploded the heads of dozens of Sea Serpent King in an instant. He slowly approached Leviathan's body as he slaughtered Sea Serpent King that kept blocking his path.

Roaaaaaaaaaaaaaarrrrrrrrr!

Leviathan felt great danger seeing Ziel slowly approaching him. The monster spawned a horde of Sea Serpent Kings to restrain Ziel and buy time for Leviathan to re-enter the sea.

"Did you think I would let you go back into the sea?" Ziel knew what Leviathan would do. But he wouldn't give the monster a chance to go back into the sea.

[Thunder Chain]

The sky turned dark as thunderclouds covered it. From behind the clouds appeared dozens of huge chains made of compression red lightning. The chains shot toward Leviathan at high speed. One by one, the chains wrapped around the monster's body and locked it.

Roaaaaaaaaaaaaarrrrrrrrrr!

Leviathan struggled and tried to break free from the chains, but another chain appeared behind the thundercloud and locked it again. At this moment, Leviathan's body could no longer move. Half of his body hangs above the surface of the sea.

"So, it's time to get the ingredients I need." Ziel flew slowly closer to Leviathan. The monster trembled after he realized he couldn't do anything else. But then, the Leviathan spewed a thick mist at Ziel. It was a mist that covered part of the sea area of the Cirlus Kingdom. After Ziel is shrouded in mist, Leviathan shoots laser beams at full power. But the attack didn't hit anything because Ziel was no longer there.

Ziel was standing right next to Leviathan's body. He compressed the red lightning into the sword. Not long after that, his black sword was enveloped in a thick red light. Then he swung his sword with all his might at the center of Leviathan's body.

[Thunderbolt Stream]

Roaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaarrrrrrrrr!

Leviathan's roar echoed through the sky. The monster was in pain because Ziel had cut its body in one slash. Leviathan never imagined that a human could defeat him. Even though Leviathan's body had been split in two, the monster was still alive. This shows that Leviathan has a tremendous life force.

Leviathan's upper body was still hanging above the sea's surface because the lightning chain locked it. Ziel quickly took the piece of Leviathan's lower body that was about to sink into the sea. Then he stored the lower half of the monster's body in his space storage.

"With this, I have obtained the ingredients I need. So, what should I do with this useless upper body?" Ziel muttered while looking at the rest of Leviathan's body. Even though it was cut in half, the monster's body still looked very large. Leviathan trembled in fear when he saw Ziel's gaze on him.

"Hmm… has the person who ordered you started moving? In that case, you must disappear from this world because your appearance is problematic." Ziel felt something while looking at Leviathan's body. Then he changed his black sword to a white sword again. Ziel stuck his small white sword in Leviathan's forehead. The monster's eyes seemed to be mocking Ziel. Leviathan seemed to arrogantly say that he wouldn't die with just a stab of a small sword like that. But suddenly, the monster had a bad feeling.

[Swallow the Gods]

From the point where Ziel's white sword was stabbed, a black hole formed and slowly engulfed Leviathan's body. The black hole is getting bigger and bigger. The black hole engulfed Leviathan's body and the fog in the area. Leviathan trembled when he saw his body being swallowed bit by bit by the black hole.

Roaaaaaaaaaaaaaaaaaaaaaaaaarrrrrrrrrrr!

Leviathan put up his last fight, but unfortunately, his efforts ended in vain. It didn't take long for the black hole to completely engulf Leviathan's body along with the fog in the area. The place returned to normal after the mist and Leviathan disappeared. The thick fog no longer obscured the view of the sea. Ziel also disappeared from there.

***

Time goes back to when Ziel dropped his second asteroid. Princess Cordelia and the academy teachers, except for Kalya, stared in awe at the scene before their eyes.

"God Beast Leviathan." Princess Cordelia spoke in a trembling voice.

"Eh? Leviathan? Doesn't that creature only exist in legends?" After hearing the monster's name from Princess Cordelia's mouth, Beatrix and the other teachers were shocked.

"I also thought so before. However, the shape and size of the monster were the same as described in the ancient book in the library of the Cirlus Kingdom. The terrifying thing about that monster was that it possessed strength on par with a True God." Princess Cordelia also couldn't believe what she was seeing at this time. She didn't expect a magical beast of that size to hide in her kingdom's territory. Flavio and the other teachers were silent, listenings to Princess Cordelia's answer.

"Could it be that monster that has made the area foggy?" Christof conveys his conjecture to Princess Cordelia and the other teachers.

"Hmm…that's possible. But we still can't be 100% sure. That is…" Princess Cordelia suddenly stopped her words when Leviathan shot a laser beam and smashed the giant asteroid to pieces.

Boooooooooommmmmmmm!

"In the book, it is said that Leviathan has an attack similar to dragon breath and can destroy an island. Before, I thought it was just bullshit, but I didn't think it was all true. After all, who is the person fighting that monster?" Princess Cordelia added her information about Leviathan. She was curious about the person who dared to fight against such a creature.

"He is… he has helped us several times. But we still don't know who he is." Flavio smiled bitterly. He was pretty embarrassed when he admitted that he had been helped many times by Ziel.

"Eh? Is he that strong?" Princess Cordelia asked without taking her eyes off Flavio. She remained focused on the battle before her eyes. She became more and more curious about that person. Even so, she doesn't believe Ziel can beat Leviathan.

"He is so strong." Kalya answered Princess Cordelia's question with complete confidence. It made Princess Cordelia turn to her. Kalya just smiled at her gaze. Princess Cordelia is still pessimistic about Ziel's power even though she sees Ziel can drop big stones from the sky.

Not long after that, Princess Cordelia could tell that Leviathan was currently in a pinch. The monster kept trying to escape into the sea. Princess Cordelia was astonished to see Ziel kill the Sea Serpent King like a bug. But suddenly, the sky darkened, and a chain of lightning appeared from behind the clouds. The chains bound and locked Leviathan.

"What magic is that? Its power to bind and hang a creature of that size? How strong was that person?" Princess Cordelia was astonished that her assumption had been wrong. Ziel was strong enough to fight Leviathan.

Eventually, Leviathan was defeated, and his body was cut in half. Ziel took the lower body of Leviathan and removed the upper body along with the fog in the area. It happened so fast that Princess Cordelia and the teachers didn't have time to say anything.

"So, we don't need to carry out our previous plan, right?" Beatrix muttered, but her voice was loud enough for Princess Cordelia and everyone else to hear.

"Yes. We don't need to do anything because the problem here is over." Princess Cordelia subconsciously answered Beatrix's muttering. They still haven't come back to their senses. The situation made Kalya chuckle.

(Who is that person? He can even defeat a legendary creature. I can only see he has black hair and is wearing an academy uniform. His age might not be that far from Rinne. Wait a minute, I feel something is odd. Didn't the teachers say they didn't know him? Hmm...interesting! He must have had some reason to hide his identity! I'll make sure to find him later!)

In Princess Cordelia's eyes, a lens formed from water. According to her will, she can see objects that are very far away or very small. Its use is the same as glasses but with a more extreme function. It was her innate ability called the Eye of the Sea Goddess. Ziel didn't know Princess Cordelia had discovered his identity.

***

In a room inside a luxurious inn in the Cirlus Kingdom, King Redis and Queen Triana are waiting for news from the Cirlus Kingdom about their son and daughter. Suddenly there was a knock on their door.

"This must be an envoy from the Cirlus Kingdom. I will meet him." King Redis quickly got up from his seat and opened the door.

"Have you guys received news about..." King Redis stopped his words because the person standing in front of the door was a middle-aged man with whitish gold hair who looked foreign to him. The man gave goosebumps to King Redis.

"Who are you?" King Redis narrowed his eyes at the golden-haired man.

"I've been looking for you, king of the Demon Kingdom. You must pay for what you have done with my research site and materials." The middle-aged man grinned, and a vast explosion swallowed up the entire inn.

Booooooooooooommmmmmmmmmmmmm!
