Invicinble Colorless Butler

Hikaru and the others were shocked after seeing the sudden arrival of the black-robed person. They had previously been prepared to take the attack from Niberus with their bodies, but the situation changed so quickly, and they couldn't immediately understand what had happened.

"Ziel…" Princess Aishia muttered after noticing the person's presence. But Princess Aishia felt that there was something strange about the person in front of her.

"Who are you? You're not Ziel, are you?" Princess Aishia is sure that the person in front of her is not Ziel. She had no proof, but her feelings told her so. The presence she felt from the person in front of her was very different from the Ziel she had ever felt. But the person was silent and did not answer or even glance at her.

It wasn't just Princess Aishia who realized it. Kyouka, who was currently injured, could also feel the same way.

(Who is this person? Why is she disguised as that person?)

Kyouka kept it in her heart and didn't question it as Princess Aishia did.

"Who are you? Why are you meddling in my business?" Niberus frowned. He could feel that the black-robed person's strength could not be underestimated. He could come without Niberus noticing and withstand his attacks with ease. Moreover, the purple flames sent chills down his spine.

The black-robed person also ignored Niberus. She suddenly disappeared and appeared behind Niberus. The black-robed person swiftly thrust out the spear that had blades of purple crystal.

"Damn it!" Niberus was too fixated on that person's presence that he caught his guard. He turned his back into a shield to withstand the attack. But he didn't expect that the black-robed person stabbed her spear dozens of times.

"Ugh!" Niberus groaned in pain as the shield he had made on his back just shattered. Luckily he quickly dodged when the black-robed person wanted to stab him in the heart from behind.

"Who are you!? Don't you know who you're dealing with?" Niberus became more careful with the black-robed person. It wasn't that he was afraid, but that he felt a strange feeling from that person. On the one hand, he was familiar, but he felt foreign.

The black-robed person still didn't want to answer and attacked Niberus. While the two were fighting, the heroes treated the injured Kyouka and Megumi. 

"Isn't he the one who helped us in the Dwarven Kingdom?" Hikaru asked the people around him.

"Hmm… I thought so too. But I always felt something was strange. Can he use a variety of weapons like you, Hikaru?" Prince Albert recalled the times of the people who helped them in the Dwarven Kingdom and compared them to the people currently fighting in front of them.

"No, I think they are different people. Isn't that so, Princess Aishia?" Kyouka asked Princess Aishia's opinion. Even though she felt that the person was different, she still wasn't sure and confirmed it to those who knew him better. Kyouka's current condition was better than before. Right now, Kyouka was casting her healing magic on Megumi while watching the fight.

"I thought so too. The aura I feel from him feels completely different." Princess Aishia answered confidently.

"I think the fighting style is different too." Princess Reina added.

"Ah! You are right! I just realized it. What's more, are you not paying attention? Even though he's covered in a black cloak, doesn't he look like a girl?" Sintaro tells them his opinion.

"Are you sure?" Prince Fritz asked Sintaro curiously.

"Hmm… then I'm not sure either." Sintaro shook his head.

"Let's put that aside for now. We'd better leave this place immediately and join the students inside the building. Each of you must bring the injured teachers. We must move quickly while they are fighting far from this place." Hikaru reminds them about the injured teachers, and they still have to save.

"We got it!" They nodded and started moving to rescue the injured and unconscious teachers.

Meanwhile, the fight between the black-robed person and the Niberus continued. Niberus was overwhelmed by being constantly attacked by the black-robed person and didn't give him time to counterattack even once. 

"Okay. Since you keep bugging me, I will fight with all my might! I want to see how long you can last!" Niberus gritted his teeth and released all his strength. Two shiny silver God rings appeared behind him. He turned his two hands into a large silver sword. His entire body was covered in dark brown armor.

The black-robed person didn't react when the Niberus unleashed its full power. This made Niberus frown as he felt a sense of danger coming from nowhere.

The black-robed person held his spear with both hands. Purple light gathered at the spear's tip and formed a ball of purple fire. Niberus swiftly slashed his sword as he sensed the danger of the attack.

[Silvergod Slash]

[Hell Fire Breath]

The waves of purple flames swallowed up the silver aura blade that Niberus slashed. The waves of fire are moving towards Niberus and swallowing him too.

"What!? What the hell is that fire!?" Niberus was taken aback as the purple flames swallowed his attack.

[Shield Cage]

Niberus enclosed himself in a group of shields that formed a cube prison. Even so, he still felt that his whole body felt hot, like it was being burned directly by the flames. The purple flames devoured their entire battle area. Fortunately, the heroes were back inside the building. The ground around them even melted and became lava.

After the purple flames disappeared, the area around their fight turned into a volcanic crater. Niberus appears in a state of the burnt body. Even one of his hands was missing.

"Who are you? I can feel the divine power from your previous attack. Are you also a divine race? Why did you attack me?" Niberus showered the black-robed person with questions.

"Since you already know it, I don't have to bother hiding it." The black-robed person said indifferently. Her voice sounded sweet like a girl. Behind her appeared 3 piles of purple sparkling god rings.

"You… you are from the divine race! Why are you helping humans!?" Niberus panicked because the number of god rings that the person in front of him was showing was more than him. Moreover, after fighting her before, he felt that the black-robed person was more experienced in combat than him.

"I don't have time to answer your question. I still have a business to do." The black-robed person suddenly stabbed the tip of her spear into the ground.

"Did you think I would let you attack me just like that!? At least I will take you to death with me!" Niberus changed his hand into the same Cannon he had previously used. This time he would fire it with all his remaining power. But when Niberus was about to point the cannon at the black-robed person, suddenly a purple snake appeared from the ground under his feet and wrapped tightly around Niberus's cannon hand.

"What is this!?" Niberus was shocked because he was completely unaware of the existence of the purple snake until it appeared. Niberus' cannon hand was wrapped in a purple snake that covered the entire cannon and made it impossible for him to fire it.

[Purple Snake Seal]

Not just one, from the ground, appeared another purple snake which wrapped around Niberus's legs and made him unable to move. When Niberus was in a state of panic because he couldn't move at all, the black-robed person had already cast her magic on Niberus.

[Hell King's Wrath]

Suddenly, a large magic circle appeared on the ground where Niberus was standing. Niberus broke out in cold sweat after feeling the divine power used for the attack. The magic circle gave off a bright light and emitted a giant purple pillar of fire.

"Aaaahhhh! You will pay for this! My lord will look for you to avenge my death!" Niberus screamed in pain from being burned alive in the purple flames. He took the time to threaten the black-robed person when he was like that. It didn't last long until the pillar of fire disappeared and left Niberus' body, which was partly charred and melted. 

"Your master won't have time to look for me. Right now, he's probably busy trying to keep his life alive." The black-robed person muttered and disappeared from the place. 

***

Time goes back to when Merlick and King Gustave fought Niberus. Ziel and Kalya heard an explosion sound from the direction of the building where the people from the academy were staying. Kalya and Laurel frowned and stared intently at Queen Jasmine.

"What have you done?" Kalya coldly asked Queen Jasmine.

Queen Jasmine could only lower her head and couldn't answer. She had already given her orders to the elven knights to follow Niberus to capture the heroes.

"Tell me, what have you done!?" Kalya asked a second time in a higher tone. Laurel couldn't help but smile bitterly and didn't stop Kalya. Right now, she was also angry with what queen Jasmine had done.

"I apologize." Queen Jasmine could only say that with guilt. Previously she had been blinded by her jealousy of Kalya and her greed for power. She realized that she had been used and only made an experimental subject that could be discarded at any time. 

"You…!" Kalya wants to say something else to Queen Jasmine, but Ziel cuts her off first.

"Leya… you can discuss it later. If you're worried, you can go over there and have a look." Ziel tried to calm her down and not waste time being angry at Queen Jasmine.

"Okay... eh? What do you mean I'm the only one going? How about you?" Kalya nods, but then she realizes the meaning of Ziel's words.

"I will go elsewhere. I have something to do." Ziel already knew what was happening there, so he let Kalya go because someone would help her there.

"Where are you going?" Kalya can't help but be curious about what Ziel will do.

"I'm going to the world tree." Ziel answered her honestly.

"What are you going to do there?" Kalya became more and more curious, and so did Laurel. Queen Jasmine and Princess Siera just listened from the side.

"Of course, finish all of this and return to the human region soon." Ziel wanted to say that he had a bad feeling if he stayed in the Elven Kingdom for too long. But he decided not to say it.

"Can I come with you instead of going to that place?" Kalya asked doubtfully. She was worried about the academy people, but she chose to go with Ziel.

"Aren't you worried about their safety?" Ziel asked her back.

"I'm worried…but I want to stay with you." Kalya said in a low voice that only Ziel could hear. But Laurel, who was not far from them, could listen to it and could only smile at Kalya's behavior.

"You can go with him, and I will go there in your stead." Laurel volunteered to replace Kalya. Even though Laurel is not as strong as Kalya, she can still be relied on in an emergency.

"No need. If you go there, it will only harm you. I've already asked someone else to help in that place." Ziel quickly refuses her help and tells Kalya that he has taken care of everything, so she shouldn't worry.

"Is that Lilith Kalya could only think of Lilith when talking about the strongest person around Ziel who could help them. Ziel nodded slightly in response. Kalya was relieved and became less worried after seeing Ziel's answer.

"Who is Lilith?" Laurel asked curiously.

"The purple-haired girl you've ever met." Kalya smiled in response. Laurel remembers the beautiful purple-haired girl she met with Ziel that night.

"Okay, we'll go now." Ziel cut off their conversation. Kalya nodded and didn't speak anymore.

"That… can I come with you?" Laurel asked timidly. She was afraid that Ziel would refuse her request.

"I do not mind." Ziel answered curtly. He tore the space in front of him and went inside first.

"Come on, Laurel!" Kalya smiled broadly and pulled Laurel into the space rift that Ziel had created. Laurel just smiled back and let Kalya pull her.. The space rift disappeared after the two of them entered it and left only Queen Jasmine and Princess Siera standing stunned at sight.
