(Others) Nagumo grew up in a family filled with great spies. So as he grew up- he went through numerous training and was a talented young man. When he entered the JCC Academy at the age of 14, he was originally in the spy department. However- he got bored of it and wanted to go astray, so he decided to shift departments and join the assassination department.

That was when he met Sakamoto, Rion, and Rui. The four of them naturally clicked being the top four greatest students in the JCC. All the teachers and staff acknowledged them, knowing that the four of them will grow into much greater assassins once they graduate.

The four of them were all close friends, but Nagumo was partially closest to Rui. Rui also shifted departments, Rui used to be in the mechanics department but shifted to the assassination department just around the same time as Nagumo did. And so both of them met. It's probably because Rui would always spoil Nagumo, that's why Nagumo was very fond of Rui.

Their fighting style revolved around each other, complimenting their skills and experience. That's why whenever they're in missions- the two of them try to fight alongside each other as much as possible since it was easier and stronger that way. They were so synchronized that people called them "one beating heart" which the both of them would always deny. Why? Because attachment is something an assassin could never have.

In the world they were living in- anyone could die at any moment. That's why everyone tried not to form any close bonds, in order not to hurt themselves once that other died. Yet the four of them ignored it, getting attached towards each other.

That's probably their greatest mistake, the four of them valued each and every one of them.

So currently, they're all currently 19 years old. Just one more year before they graduate from the JCC academy. The four of them were waiting at a parking lot, about to go on a mission. However this one was different, usually it was only the four of them going to missions since no other students were able to keep up with them. But in this mission, their teacher added one student in this mission. Which was already late, so much for a first impression.

In the JCC four people left quite a mark in their history. Nagumo, Sakamoto, Akao, and Rui. Those four were menaces back then, not only did they set records that no one has ever beaten- they were all great assassins. That Quadro was special, one in a billion they said.

Although- everything has its end

Now- amidst of their 20s- Nagumo was the only one left. Akao died, Sakamoto retired and became a husband and father, and Rui was missing and presumed dead

Their youth is something that'll forever be in their heart, no matter how much they try to brush it off

Back in JCC when they were 19 years old

Nagumo grew up in a family filled with high labored spies, they were top tier in the pyramid. However- who would've expect that their son; Nagumo would lead astray and join the assassination department instead? Little did Nagumo know, that'll be the best decision he ever made

Not only did he meet Sakamoto and Akao- he met Rui. Although they were all close friends, Nagumo was partially the closest to Rui. Both of them were synchronized. All of their actions, personality, thinking, everything. That's why as much as possible, whenever the four of them were in a mission- they always made Nagumo and Rui pair up since their skills were like they were one people

They were often complimented, saying the two of them were practically one beating heart

However- the two of them always denied it, simply saying that their teamwork was only for efficiency. After all, getting attached in this world is something that every assassins would like to avoid. Relationships and connections are practically something assassins could never imagine having

Yet no matter how much Rui and Nagumo denied their affection towards one another, the more their bond seemed to deepen and deepen

Now, the four of them were all in a parking lot. Apparently in this mission- they weren't the only ones going, which was weird. Usually it's only the Quadro since no one else was able to keep with the four of them, but this time their teacher added one more student

Nagumo hummed, playing with his pockey as he bit one of it- simply relaxing inside the car at the second row. All four of them were patiently waiting for the other student who's joining them, which is already late
