Invicinble Colorless Butler

The classroom door is open. The first to enter was a boy with short red hair, he had a face similar to King Gustave. He was the first Prince of Rubelia Kingdom, Albert Rubelia. After him, four people who had facial features not common in the Clorius continent entered one by one. Two boys and two girls. The students wonder about their origins. The five of them including Prince Albert stood in front of the class.

The Princesses except Princess Reina don't recognize them because the heroes' enrollment to the academy is kept secret. Clara looked at the four people because they had facial features somewhat similar to Ziel's.

"Alright, please introduce yourselves." Flavio asked them to introduce themselves. He smirked and waited for the next surprise.

"I am the first Prince of Rubelia Kingdom, Albert Rubelia. I am glad to be your acquaintance. Since we will be classmates, you can call me Albert." Prince Albert smiled gently which made the girls in the class blush. It made the boys not happy to see him.

"My name is Megumi Himeno, nice to meet you all. Please take good care of me from now on." The next person to introduce herself was a sporty blonde girl with ponytails. She is the kind of jovial girl from the way she talks.

"I'm Sintaro Yariba. I'm glad to be your acquaintance. If you need any help, don't hesitate to talk to me." A short blonde-haired boy with a tall, muscular build was the one who next introduced himself. He looks like someone who solves any problem with muscles.

"My name is Hikaru Tenshiro. Please be good friends with me." The one who spoke was a boy with short, neatly trimmed black hair. He wears glasses that make him look intellectual.

"Kyouka Hanasaki. Nice to meet you." the last person to introduce herself briefly and coldly was a beautiful girl with long straight black hair styled in a braid on the side. She looks like a conglomerate Princess.

The students in class S began to be noisy in response to their self-introductions. Princess Reina waved her hand while smiling at them from her seat. This shows that Princess Reina knows the new students.

(Hmm... Why do I feel their facial features and name accents are similar to Ken)

Clara muttered in her heart. Ever since they entered the classroom, he had sensed that there was a similarity between their facial features and Ziel's. She was even more convinced after hearing their names. She looked at Princess Iris who was sitting next to her. Coincidentally, Princess Iris also looked at her. She also thought the same as Clara.

"Mr. Flavio, may we ask them a question?" One of the students in the class raised his hand and asked permission to ask out of curiosity.

"Sorry, but you can ask them during your lunch break and start acquainting yourself with them. Ah, there is one thing I must tell you. I've been permitted for this. After all, it's no longer a secret. The four of them are heroes summoned from another world." Flavio smirked after saying that. He wanted to know what kind of reaction the students would show. But unexpectedly, the students including the princesses who didn't know about it fell silent due to Flavio's words.

"Uh, are you serious!?"

"They are heroes!?"

"They're from another world!?"

The students' reactions were a little late as they first digested what Flavio said, after knowing what he meant they were completely dumbfounded. They never thought that the new students in their class were heroes, much less from another world.

"All right, please calm down! You can sit on the available empty seats. We will start our study." Flavio was satisfied with the student's reaction and allowed the new students to take the empty seats of their choice.

Hikaru, Sintaro, and Prince Albert chose seats adjacent to Princess Reina and Princess Rinne. Even though Princess Rinne knew from her father that the Rubelia Kingdom summoned heroes from another world, but she never had the chance to meet them in person.

The place where they sat was also close to Princess Freya and Princess Aishia. Because the Princesses choose seats that are close to each other except Princess Iris.

When Hikaru and Sintaro saw the gold and silver-haired Princess, they smiled broadly. Princess Freya and Princess Aishia nodded slightly in response. They couldn't ignore the hero who was the messenger of the gods to keep the world's peace. But the male students including Prince Fritz were annoyed to see his gaze on Princess Aishia and Princess Freya. He could only suppress his anger by gritting his teeth for now.

The other two new students, Megumi and Kyouka, are sitting next to Princess Iris and Clara. Since the seats around the princesses were full, they decided to sit where it looked more serene and quiet.

"Hello! Nice to meet you. I'm Megumi, Since we'll be classmates from now on, you can call me Megu." Megumi reached out and offered a handshake to Princess Iris and Clara.

"I'm Iris Neigal and the girl next to me is called Clara Castilene. I'm honored to meet you, lord Hero." Princess Iris politely accepted her handshake. She glanced at Kyouka who looked like she had no intention of socializing with them.

"I...Clara. Nice to meet you, lord hero." Clara is still awkward when it comes to getting to know strangers.

"Ahaha... I beg you guys don't call me with honorifics. It makes me a bit ticklish. Right Kyouka?" Megumi glanced at Kyouka who had been silent all this time. Since Megumi continued to stare at her without batting an eye, Kyouka couldn't help but sigh.

"My name is Kyouka, I'm glad to be your acquaintance." Kyouka offers a handshake to Princess Iris and Clara. They gladly accepted it.

"Hmm... May I ask you something?" Clara ventured to ask Kyouka.

"What do you want to ask?" kyouka seemed not interested in what Clara wanted to ask, or rather not interested in the people around her.

"Oh, nothing." Clara shrank after receiving a cold response from her. Kyouka just kept quiet and didn't ask Clara any further.

"Hehe... You don't have to think too much about it. She's like that, but she's not a bad girl either." Megumi whispered to Clara. But her voice was heard by Kyouka next to her.

"What are you talking about?" Kyouka narrowed her eyes at Megumi.

"Ahaha... It's nothing!" Megumi stuck out her tongue like she didn't care that Kyouka would get angry. After that, their learning begins with the heroes as new students in the class.

Time passed quickly and it was already lunch break, the usually busy academy cafeteria now seemed deserted. Ziel arrived at the cafeteria and immediately ordered his food. While he was looking for an empty table, he saw Clara waving at him. As usual, Princess Iris was also with her. Apart from that, there were also other people accompanying them. She is Lilith. She approaches Clara and tries to befriend her as Ziel ordered.

Ziel sat with 3 beautiful girls who caught the attention of the male students around him. Ziel felt Princess Iris' gaze as he sat down in his chair. But when Ziel looked back at her, Princess Iris quickly averted her gaze. Then Ziel introduced himself to Lilith. He pretended to be meeting her for the first time. Princess Iris raised her eyebrows after seeing Ziel and Lilith's acting as they got acquainted. She had already seen Lilith in Ziel's cottage when she woke up. So there was no way Ziel and Lilith didn't know each other. But Princess Iris didn't dare to say anything.

"Ken, do you know about heroes..." Clara hadn't finished her sentence and was already interrupted by the excited screams of the surrounding students.

"Wow look at them!"

"Those are the heroes!"

"They came with the Princesses and Princes!"

The group of heroes along with the Princesses and Princes made all the students in the cafeteria excited. Ziel glanced at the group for a moment, then returned his focus to his food. He had no interest in those heroes at the moment. Ziel and the others at his table could hear their conversation.

"Princess Aishia, Princess Freya, how about we sit at that table?" Hikaru suggested that to the two Princesses. He had been intrigued from the first time he saw them.

"That's right Princess. The table is big enough for all of us." Sintaro helps Hikaru because he is also interested in them.

"Okay." Princess Freya nodded slightly accepting his invitation. She felt bad if she had to refuse the heroes' invitations. Her eyes glanced at the place where Ziel was sitting.

Hikaru and Sintaro sat next to Princess Aishia and Princess Freya. This not only annoyed Prince Fritz but also Princess Reina.

"Ken, I think your name accent, and facial features are similar to those of the heroes. Could you be..." Clara whispered to Ziel. But the other two girls at the table heard him. They all stared at Ziel waiting for an answer from him.

"You must be joking, my lady. How can I look like the heroes? I was born and raised in this world. As for the name accent and facial features, it's all coincidence. Or maybe my parents are still descendants of the heroes hundreds of years ago." Ziel tried to convince them with his words.

"That makes sense." Princess Iris subconsciously nodded repeatedly after hearing his answer. After she realized that Ziel was staring at her, she quickly turned her gaze back.

Not long after, Kalya and the other teachers who had just finished with their business came to the canteen.

"Wow, a real elf! This is my first time seeing it in person!" Sintaro stood up and was about to approach Kalya out of curiosity. He thought by being a hero, he could do anything. Before he could get close to Kalya, suddenly something astonishing happened.

Boom!

"Ugh...what is this!" Sintaro suddenly knelt. The floor around where he was kneeling cracked from the force of the impact on his knee.

"Sintaro!" Megumi quickly got up from her seat and helped him up.

Kalya glanced at Sintaro who was kneeling then saw Ziel who was eating with 3 beautiful girls. She more or less understood what was going on. She smiled sweetly at Ziel. Fortunately, this was only seen by Princess Iris who was intentionally paying attention to Kalya's behavior.

"Sintaro, are you okay? What happened to you?" Hikaru approached him. Then he checked his condition. After one month of being summoned to that world, their relationship was quite close.

"Ah, I'm fine. It seems my powers are out of control." Sintaro replied uncertainly. Coincidentally one of his innate skills was [Gravity King]. So he thought that something was wrong with his skill. They were relieved that nothing serious had happened to him.

Not everyone believed what he said. Two people were very sharp in responding to the situation, the first is Princess Freya who understands what is going on because she keeps glancing at Ziel from time to time. The second was one of the heroes, Kyouka Hanasaki. She looked around to find the person who had made Sintaro like that. She tracked it down using magic but still couldn't find anything. Normally there would be traces of mana after you used magic, but right now he couldn't find the slightest trace of mana as it didn't exist in the first place.

(I'm sure someone else used magic on sintaro. But who? I couldn't even detect it when that person used that magic)

Kyouka frowned and started to speculate in her heart. She still kept looking around the cafeteria to find the person, though her efforts were in vain. Sintaro and the others had returned to their seats.

"Aishia, you better try this. I think you'll like it." Hikaru tries to offer his food to Princess Aishia. Since it was uncomfortable to refuse, she finally accepted it with a slight nod. But before the food fell onto Princess Aishia's plate, someone shook it first until the food fell to the floor.

"That's enough! Don't you see that Aishia is bothered by your attitude! Don't act as you please just because you're a hero!" The irritated Prince Fritz shouted at Hikaru.

"Hoo... So what do you want, Prince?" Hikaru intentionally provoked him.

"I will challenge you to a duel with me in the battle arena!" The provoked Prince Fritz challenges a hero to a fight.
