The next day, Kai and Sofia had arrived at the school. The building was similar to his school back in the US Base, but the scale was far larger as if it was for more students. The moment they entered, they found a giant field where many students actually fought against each other.

Right in front of him, the student took his breath away, not because of her beauty but due to her weapon.

"What's that?" Kai asked.

Sofia smiled and pointed at the white spider legs that were on her back. "That's also a part of the exoskeleton. You can say it's the extension. If the exoskeleton is normally used to defend your body from incoming harm and boost your physical abilities, those legs can actually be controlled to move together with you and become your weapon."

"Heh?" Kai narrowed his eyes as the technology piqued his interest.

"Can you see there is something on her neck, running through the back side of her cheek and connected to her head?"

Kai nodded. "Yes."

"That's connecting the legs to your brain. It will move according to the brainwaves. Of course, calculating your own brain waves is hard and needs so many trials and errors. Even that person needed around two years to reach this level of control."

"You know her?" Kai asked.

"Yes. She is the escort that Arnaud talked about, you know." She stuck her tongue out.

Kai took a step back and widened his eyes. He once again checked the girl.

She had long light blue hair tied into a ponytail to tidy it up. Her blue emotionless eyes showed that she couldn't be easily shaken by something, so Kai felt that this girl wouldn't talk too much.

At least, she wouldn't be so annoying.

The girl spun her sparring partner's body and struck her on the stomach, ending the match right there.

"Thank you, Roselyn. It seems I can't win against you today." Her opponent chuckled as she fell on her butt. "I'm tired."

"No. You're already strong enough." She shook her head.

Suddenly, killing intent spread around before moving to target her. She flinched, took a few steps back, and took out a shield while blocking the sides with her eight spider legs.

Raising her head, she found a male that perfectly fit the description Arnaud told her and instantly realized who he was.

'Seriously?' Roselyn gulped down, wondering if someone like this truly needed protection. In that killing intent, she literally felt as if Kai was in front of her, choking her neck.

Kai, on the contrary, never really used this type of move because he never felt the need to be in the US Base. But since the Union wanted to monitor him, she needed to be someone capable or else she would end up becoming his burden.

He didn't mind taking care of a few people in the US Base, but he had nothing to do with the EU Base other than Sofia, so he wanted to see this person's ability.

At the very least, she seemed to be sensitive enough to sense a killing intent from fifty meters away, so it should be enough for her to escape if he ordered her too.

'So, that's Kai Carter…' Roselyn took a few deep breaths and calmed her heart down. 'How many magical beasts has he killed? Few thousand? No, I believe it's already beyond tens of thousands… No way, is it really above one hundred thousand magical beasts?'

She wiped the sweats on her forehead and tidied up her appearance as she walked toward Kai Carter with a serious expression.

Her sparring partner was confused by her action, but it was answered when she saw Kai Carter staring at them from the school gate.

While waiting for her to arrive, Sofia decided to introduce the girl. "She is the number three of this school. Because of her specialty as a defender with that shield you saw earlier, she has been nominated to escort you around.

"Her name is Roselyn. Well, you have been informed that our school doesn't have the US Base's group system, but we have something similar. To be honest, you are to search for a mission alone. The mission itself comes from the military, so there are many people who will come for that mission on the due date.

"Then, you basically need to team up with those people there according to the orders from above. In other words, unlike the US Base that teaches the synergy for each group and has them lasted for long, the Union wants adaptability from the people here.

"After all, if someone from a team dies, the remaining people are required to get another person or continue as it is. That's why we don't adopt the group system. Of course, the synergy won't be as good as yours."

"I see." Kai nodded in agreement, knowing the reason why they implemented such a system. He contemplated until he heard that Roselyn had arrived before him.

"Hello, I am Roselyn Breguet. I can't speak Japanese, but I think my English is good enough to keep up with the conversation." Roselyn spoke in English and stretched her hand. "It is my honor to help Kai Carter during his stay in this school."

"I am Kai Carter. Nice to meet you." Kai nodded. Although he wasn't pureblood Japanese and United Asia, in fact, had so many languages, they still used Japanese to talk on a daily basis. It was to honor Japan to take them in as a refuge in the past. Even though they changed the name to United Asia, they still held it in high regard.

However, Kai and his family still spoke English from time to time back in the house, so he didn't have a problem talking to Michelle in the past and had no trouble talking with others in the US Base from the start.

Still, he wondered whether he should learn French, so she could speak easily in this place then realized that it wasn't worth the time. Instead of learning other languages, he better learned other races' languages.

They shook hands with a smile.

Kai could see that her spider legs had been compressed to a simple box attached to her back. It was around a lunch box in size, so she shouldn't have any problem or whatsoever to have it attached on her back.

"I don't know if you have heard this, but I have three primary jobs. I will accompany you anywhere you want to go since I need to report it. Of course, you have your freedom in your room or bathroom unless you act suspiciously. Then, if you have any requests to the Union, I will do my best to relay your message to them.

"Third, I am going to fight together with you in every single mission and you are allowed to make me do anything." She explained while raising three fingers.

"Do anything, eh?" Sofia suddenly smirked and looked at her. "Including sexual activity?"

"Ehm… Yes." Roselyn nodded with a poker face even though she hesitated for a second. She thought and took one step back, putting her right hand above her chest and her left hand on the waist. "My bust is 85 cm, my waist is 86 cm. I have confidence that I will be able to bear a good child."

That was a pretty but unusual introduction. Even Sofia was amazed by the boldness.

However, Kai shook his head and sighed. "You should say it when you're comfortable with it. Anyway, I won't make you do something like that. Don't worry."

As one would expect, the hesitation in her tone was easily caught by Kai's ears.

On the contrary, Roselyn felt both relieved and hurt at the same time as she facepalmed. "I wonder if I should be hurt to see you not finding me attractive or feel happy that you're a good person. Well, I'm a direct subordinate of the Union and they ask me the same thing as they want from Sofia. I should say this from the beginning since I don't want a misunderstanding or offend you in any case.

"After all, the moment we surrender ourselves to the Union, we need to follow any command no matter how ridiculous it is." Roselyn let out a long sigh before smiling. "Anyway, that's everything. Do you have a question?"

"Not really." Kai shook his head. "I am just wondering if I can call the people in the US Base since I don't know whether the Union will tap it or not."

"Ahaha, even I don't have the answer to that question. But I can ask my superior about it."

"Nah, it's fine. It's only three months anyway, so I can bear with it." Kai shrugged without a change of expression as if he had prepared for something like this.

Little did Sofia and Roselyn know that Kai had gotten a direct line that allowed him to call the people close to him and the government if she felt troubled or just wanted to share his love with his close ones.

"Anyway, I'm new here, so I don't know anything. What should I do first?"

"The school has a seminar every single day for each grade, but not many participate in it because they don't have an interest in it. And most of them are on a mission, so I don't think you need to come to the seminar.

"Grandfather has completed the registration process for you, so you only need to grab the key to your dorm from him right now. After that, I can guide you around the school," answered Sofia with a poker face.

"Well, I need to follow you wherever, so please excuse me. I hope you don't mind." Roselyn gently scratched the back of her head with an apologetic smile.

Kai thought for a moment and decided. "Let's deal with the formality stuff first."
