Invicinble Colorless Butler

The next day the residents of the Dwarven Kingdom were shocked by the explosion of fireworks that occurred in the night sky. Not only the residents, the students, and teachers were also shocked by this incident. In that kingdom there was no tradition of fireworks, so the soldiers in the Dwarven Kingdom thought it was a monster or enemy attack. King Auva and his two children panicked because of last night's incidents. King Auva ordered the soldiers to find the source of the explosion.

Only the heroes knew about it, but they couldn't find the source of the fireworks either. Among the heroes, only Kyouka seemed to be still looking for it. She thought the slightest hint would be useful for them to return to their original world.

Today was the third day the academy students went on a study tour. They will be brought to the Golem Manufacturing Facility which is not far from the royal castle. Right now Princess Freya was walking side by side with Princess in the corridor. She came to pick up Princess Iris because their rooms were close to each other. Even last night Princess Freya played into Princess Iris's room.

While walking down the corridor, they heard the sound of footsteps behind them. They turned and saw the person walking behind them was Kalya. Her face today is very different from yesterday. She was more bright, cheerful, and beautiful than usual. The two Princesses were bewildered by the changes that had occurred in just one night.

"Good morning Princess Iris and Golden Hair Princess." Kalya greets them with a smile. She calls Princess Freya by a nickname.

The two Princesses fell silent after hearing that. They are shocked by Kalya's behavior today. She would usually just nod when she passed them. Not only did she greet them but also gave a smile of a maiden in love. This made the two Princesses envious to see it.

"Why are you silent?" Kalya asks both of them who just stood staring at her.

"Are you okay, Miss Kalya?" Princess Iris asked her back because Kalya's current behavior was very strange.

"I'm very healthy. Can't you see it?" Kalya tilts her head cutely. She was confused by her question.

"Are you that elf?" Princess Freya looked at Kalya from head to toe. She didn't think the girl in front of her was kalya.

"Aren't you being rude to your teacher?" Kalya bulged the veins on her forehead after hearing Princess Freya's words.

"Ahaha...I'm joking. You surprised me with your sudden change in mood." Princess Freya smiled and looked away awkwardly.

"Okay, I was just joking too. You guys better head to where the academy students and teachers gather before it's too late." Kalya reminds them and walks first to the gathering place.

"Oh, okay." Princess Iris and Princess Freya followed behind her.

Along the way, Princess Iris and Princess Freya kept staring at Kalya's face. They felt this must have something to do with Ziel.

"Did something good happen to you?" Princess Freya finally asked because she couldn't suppress her curiosity. The question also represents Princess Iris' feelings.

"Shouldn't you already know?" Kalya smiled slightly at them.

"What is it? Can you tell me?" Princess Freya is getting more and more curious about her words.

"Of course, I got a present last night." Kalya answers honestly.

"What!? What's the gift!?" Unexpectedly the person who asked was Princess Iris. She even raised her voice when she asked. Kalya and Princess Freya looked at her. This made Princess Iris aware of her previous behavior.

"Sorry..." Princess Iris shrank and lowered her head. Princess Freya smiled bitterly at her. Princess Freya smiled bitterly in response. She felt that she would get another love rival.

"So, what did he give you?" Princess Freya returned to her previous question. Princess Iris is also waiting for her answer.

"Didn't you guys see it last night?" Kalya gave them a hint.

"Last night...? Don't tell me the beautiful explosion in the sky last night was..." Princess Freya already knew the answer.

"Yes. The explosion was called a fireworks display, he said. It was to decorate the sky with something beautiful in a romantic moment." Kalya smiled beautifully at both of them. She recalled what happened last night with Ziel.

"Are you showing your affection for me!?" Princess Freya gritted her teeth in jealousy. On the other hand, Princess Iris pouted upon hearing that.

"What did you say? Didn't you ask me?" Kalya tilts her head and pretends to be innocent. The two Princesses were silent and could not answer.

(Haa... Right now you're acting like a girl the same age as them)

Silphy sighed seeing Kalya teasing the two Princesses.

(Sometimes acting like that, I don't think it's bad)

Kalya smiled enjoying the reactions of the two girls in front of her.

"Ah, I have to go soon. Try not to be late." Kalya quickens her footsteps and leaves them behind.

"She's like the happiest woman in the world." Princess Iris muttered as she watched Kalya leave with light footsteps. She could feel she was in a very good mood from her current behavior.

"I would feel the same way if I were in her position. Let's go after her." Princess Freya smiled bitterly and walked with Princess Iris following her who had left them far away.

By now the students had already gathered in the front yard of the castle. They will be doing their third-day study tour. Their current destination was the golem manufacturing factory and was one of the vital places in the Dwarven Kingdom. Merlick and the teachers didn't know why King Auva dared to point out that place to the people of the human region.

But they didn't think about it too deeply, they considered it the good manners of the Dwarven kingdom to invite them to come.

Right now the students were still waiting for some of them who had yet to come. They still had time before their departure. The heroes and royalty were already there. Kyouka who was also in the group kept looking around like she was looking for someone.

"Kyouka, what are you looking for?" Megumi asked her after noticing Kyouka who kept looking at the crowd of students.

"I was looking for the boy from yesterday. Princess Iris, Princess Freya, and everyone we met yesterday was already there. But I didn't see him at all." Kyouka thought that Ziel hadn't come this time. But everyone she saw yesterday had already gathered. This confused her because she couldn't find him.

"Be careful, Kyouka. You could be obsessed with him if you keep like that." Megumi chuckled teasingly.

"You must be kidding. I'm just curious about all the facts we found yesterday. You already know about me, right? I have to find the answer from him." Kyouka replied seriously to Megumi's words.

"Haa... Don't blame me later because I already warned you." Megumi shook her head and no longer bothered Kyouka who was looking for Ziel.

On the other hand, Hikaru is currently chatting with Prince Fritz and Prince Albert. Although previously there was an argument between Hikaru and Prince Fritz, now they were like friends.

"Fritz, I didn't see Freya today? Is she with them again?" Hikaru looked around and didn't find Princess Freya.

"You're right. As long as she doesn't do anything dangerous and tarnish the reputation of the Aurelia kingdom, she can do whatever she wants." Prince Fritz explained to Hikaru. After he saw the smile that Princess Freya showed yesterday, he realized that his sister seemed happier with her friend now.

"Is that so?" Hikaru looks disappointed that Princess Freya is not with them at this time. There is indeed a Princess Aishia, although she is no less beautiful than Princess Freya, she is more passive in conversation and a bit cold.

"Don't worry, we'll take them to lunch next time." Sintaro patted Hikaru's shoulder. He knew how his friend felt. Hikaru nodded in response but his mood didn't change at all.

Not long after, the students had already completely gathered. Today's study tour will be guided by Prince Torin and Princess Melkia. The two of them will accompany the students. This was because the place they were going to was a very important place for the Dwarven Kingdom.

They set off in a magic car to go to the Golem Manufacturing Facility. They only spent a third of their time commuting to the Magic Tools Hall to get there. That's because it's not that far from the royal castle.

The magic car entered what looked like a military base. The security is even more strict than in the Magic Tool Hall. In various corners of the place, many soldiers and golems stood guard. The type of golems there is also different from the golems that are guarding the royal road. Because the golems in that place are more like humans and their entire body is golden-silver.

The students stopped right in front of a building. Unlike the buildings they had visited before, the building in front of them was not a multi-story building but only a one-story building. But it was bigger than the flower garden they had visited yesterday. The most striking thing is that all the walls are made of metal. It's not an ordinary metal either, but adamantium which is one of the hardest metals in the world.

"My brother and I will be your guides today. As you all know, this place is important in the Dwarven Kingdom. So I ask for your understanding to act more carefully. We will guide you to a place that has obtained approval from my father, King Auva. So please follow us quietly, if there is something you don't understand and want to ask, we will gladly answer it as long as it's not a royal secret." Princess Melkia stood with Prince Torin looking at the students. They were currently right in front of the Golem Manufacturing Facility entrance.

Prince Torin and Princess Melkia were the first to walk towards the entrance and were followed by the students behind them. They had to pass through a layered security door to get to their destination. Along the way, the students saw the bodies and spare parts of the golems being carried by the workers there.

"This is the first place of our study tour, the golem assembly site." Prince Torin smiled and showed a place full of golem body parts that were assembled one by one with magic.

"This looks like making a robot with magic." Hikaru muttered looking at the golem assembly process in front of him. It wasn't like the golem-making he had been thinking about.

"The golem body parts created at the blacksmithing site are still part of this place and sent here to be assembled. Apart from that, all the other important parts of the golem were made directly in this place. Could this kind of process be familiar to heroes in their original world?" Princess Melkia explained further after overhearing Hikaru's words. She was curious about what he had said earlier.

"The only difference is that everything here is done with magic, especially the power source for the golems to move." Hikaru smiled answering Princess Melkia's question.

"You should tell me more about it after we get back to the castle." Princess Melkia holds Hikaru's hand with sparkling eyes. He is very interested in Hikaru's story.

"Of course." Hikaru gave a small nod at her request. He averted his eyes in embarrassment at what Princess Melkia did to him.

After that, the students were taken to another place in the building. They move from one room to another. Until finally they arrived at a place where the room looked the most different from the others. The room was very large and contained a tall, thick glass case with adamantium-grade hardness. In addition, there is a thin barrier on the surface of the glass. What was inside the glass case was a giant silver-gold golem that looked like the famous mecha robot in Japan.

"This is Amalgam. The origin of all the golems in the Dwarven Kingdom." Prince Torin began to explain to the students about the golems in front of them. The students watched in awe while still paying attention to Prince Torin's explanation.

After finishing the activities in the room, the students were taken to a very large area where various golems lined up.

"This is the place where the finished golems go through the final process. You are allowed to look around but are forbidden to touch the golems. Do you understand!?" Prince Torin shouted so that all the students could hear him.

"We understand!" The students answered in unison and spread out to look at the various types of golems in that place.

Ziel decided to separate from the rest of the group including Clara and the others. He kept walking and looking for the quietest place in the room.

"All right, you guys can get out now." Ziel looked at the shadow hiding behind the golem.

"You noticed? Aren't you just a student from class D?" Kyouka came out from behind the golem and was followed by the other heroes. They are covered in a mana membrane that covers their bodies. It makes their existence invisible even though they are not as perfect as Princess Freya's abilities.

"Just intuition." Ziel shrugged his shoulders.

"Then I won't mince words anymore. Who are you? Where are you from? Are you Japanese like us?" Kyouka glared at him. The hero behind her also did the same. They're like saying don't play with words in front of them. But Ziel didn't answer right away. He seemed to be waiting for something.

Not long after, the building shook slightly and a warning sound echoed throughout the place.

"Heroes from another world, I think it's time for you to do your duty and prove that you are worthy of being called Heroes.." Ziel said to them indifferently.
