They stand in front of the office of the president, from Elio's detection, five people are walking, and he is showing a number with a gesture to Mio. Once Mio nods, Elio throws a small capsule in it, in a few seconds, fog is full over the entire room.

"What the heck!!"

They tried to cover their mouth, but their secret grim reapers were already standing behind them, a blade easily traded three bullets, they swore and provoked before they stepped into the gate of the abyss. None of Mio's or Elio's moods didn't swing slightly.

Little mice were trying to escape, and Elio finished him quietly. Mio doesn't praise him, because she knows students from Human Academy, the first lesson would be to kill a living creature, or they might be killed in their first course.

"Three more are coming toward here."

Elio wanted to finish them, but suddenly Mio pulled him back, their eyes were locked on those crops. They move to them quickly, searching for things in their clothes, they spend a little time to finish, but with no luck. The black box isn't on their hands.

Mio checks on her watch, three moving marks are getting closer and closer, Mio waves her hand slightly, and Elio reads her sight immediately. Using the sofa to cover themselves, Mio is using this small break to clean her blade, it looks like she doesn't care who will come into this office, she believes that she can kill that person effortlessly.

When the door opened, they heard a guy using an arrogant pitch to demand his subordinate. "Find it! That thing has to be in this room."

"Noted."

They stand separate in different places, Elio loses his finger from the trigger and sneaks close toward a man who squats near the lower drawer, Elio moves close enough and grabs that guy's face with his palm, and Elio's free arm clamps to his neck, a heavy and suffocatingly movement taking all the oxygen from this UNION guy. Confirmed he could no longer move, Elio pats his head slightly.

"Too slow."

Mio stands behind Elio, She has killed two people and saw the whole killing progress of Elio, It took more time than she expected.

Elio heard her comment, and he regretted it soon, that was the best chance for him to show Mio that he was useful, but he thought Mio wouldn't care about what he did. Elio smiles shyly and hides all the questions back to his belly, they are getting close, but not close enough, Elio wants Mio to treat him as a mentee officially.

"I'll do it better! Next time!"

"Whatever, go search that drawer." Mio points to the closest bookshelf near to Elio.

While Elio is searching that bookshelf, Mio goes over the whole structure of this room, it gives her a weird sense, that she ignored that coffer which was clearly opened by someone before. Step closer to a vase, and she picks up a small black triangle, Evelyn scans it from Mio's goggles."Mission completed. Congratulations, Mio." 

Elio thought he heard something strange because Evelyn overstepped the bounds of authority, he couldn't help but frown a bit, and then he heard Mio suddenly curse to the air. "Don't call my name, idiot!"   

"Why do you know they hide it over there?" Elio tries to calm Mio down and he successfully gains a cold glare from Mio. Maybe she finds out she lost her temper for one second, she looks totally normal right now, still cold like a stone, there is only one difference before Elio came to this mission with her.

Mio doesn't bother to explain things to Elio. "Safer isn't empty, those valuable metals of Mr.Bale are still inside. So I guess UNION had come here before, but they didn't find the right thing."

Mio threw that black triangle to Elio, it looked quite different from the other target. Even though Mr.Bale had requested Nuée to get these back, and from his words and the things Mio found, Elio has an instinct that Mr.Bale doesn't want Nuée to know that much about his trade secret.

"Ms.Adrian you must be a genius!!!!! I'm so glad that I can work under your guidance!!"Elio turns to Mio, he is excited about Mio's observation.

"Stop sugar-coated me. I'm not going to buy it. Don't forget we should run to the rooftop before counting stop."Mio doesn't feel good around a tale-shaking puppy.

"Yes! ah, Can you wait for a second? I thought I was misguided by my watch, turns out, my doubt is meant to be solved. There is definitely hiding someone inside."

"Hey!! Whether a living creature is hiding in it or not, Our mission is completed! Don't waste my time to search for some unidentified crisis!"

Elio is concentrated on pushing the bookshelf, and he easily pushes it into space, he finds a small door hidden behind a bookshelf, Mio tries to drag him back, but Elio already sneaks into that door.

"Helicopter will arrive in 5 mins. Please go to the rooftop as soon as possible."

Evelyn is rushing them.

Elio hears another voice from that small space.

"Please, Please help my daughter..."

"Who are you? How can I help you?"

Elio moves closer and finds a woman with tear marks on her face.

"Help me, please!! I brought my daughter to my workplace, I thought I could spend a day with her in my boss' office, Suddenly, the alarm rang when I heard something explode while I was playing hide and seek with my baby girl...Oh god, please save my daughter, my name is Nancy, and I can pay you anything you want...Please!!"

Elio guides her out of that small door, from her words, they catch several keywords, but it doesn't mean they know where to find this poor woman's daughter.

"We got to go, bring her with us."Mio isn't bothered by her request. She has seen plenty of people asking for help, receiving personal requests is prohibited.

"Please!! I will pay no matter how much it will cost!!"Nancy's shaken body can't even stand straight, her hands are grabbing Mio's clothes, She seems like she doesn't care to lose one or two fingers. But Elio is a new member of Nuée, for him, Nancy's request is simple, Mio slaps his hand before he tries to speak.

Mio faces Nancy, and says firmly."Since you have hidden in this place once UNION breaks into this building, I assume you know they are a group called up people who have no moral and ethical standards. We do take control of a current situation, but it doesn't mean they will choose withdrawal. They would only send more and more members in here. You can follow my tail, I'll let you come with us, or you can stay in here miserably, try to prey for mercy from them."

Nancy is terrified, she looks like a cat stole her tongue, buries those arguments back into her heart, and she understands how weak she is. But it doesn't mean Elio fully supports the speech of Mio, He understands most people don't have special strength like them, and that's the reason he tries to convince his mentor. "I can search this floor. Ms.Adrian can escort her to the rooftop. Evelyn, please scan this floor."

"Mr.Kishi, Evelyn has to reject your request. Nuée will not allow any personal use for detection or analysis."

"Why! I only need you to check if there are any vital signs!"

"Please refrain from any mission-irrelevant actions. Please head for the rooftop. The helicopter will be arriving shortly."

 "Once I found her, I'll run toward it!"

Elio and Evelyn are arguing about things that make Mio feel unpleasant. A human who acts without permission, An AI talks like a stupid robot, Mio is counting on her watch, and she looks at Nancy.

"I don't understand the point of saving a non-mission objective. Please follow Nuée's instructions."

"I don't care if you can understand or not! A human is being in front of us and she needs help! We can't abandon a little girl stay in this harsh environment!" Elio is losing control, his argument with Evelyn has escalated, Mio doesn't want to hear their stupid arguments anymore, and she also hates to get involved with 'human rights'.

"Evelyn can't understand. Mr.Kishi, you are a probationary agent of Nuée. You will help many people who have an impact on the world. Why would you help a young living creature that you don't know her future value."

"Are you trying to say that you only see two types of humans? Don't use this word to describe a life!"Elio is furious, He wants to tear Evelyn into two pieces, if Evelyn has a body, Elio is sure he won't regret making his imagination come true.

"Evelyn absorbs knowledge that my creators want. You can explain it to me, I'll try to analyze it."

"Stop it."
