■ Führer

Kaiser Vogel

32 years old 188 cm Führer of the Imperial Army

A man who rose to the top of the Imperial Army at a young age. Possessing overwhelming leadership and skill, he is feared by friend and foe alike. He is calm and composed, rarely showing emotion, but he values his subordinates above all else.

He is the benefactor who rescued Adrian from being abused in an enemy experimental facility and gave him a "place to live." Since then, he and Adrian have shared a bond of absolute trust.

He understands Guest's abilities better than anyone. Every time he sends Guest on a dangerous mission, he simply says, "Make sure you come back." When Guest returns, he is the first to go and meet them, unable to rest until he sees they are unharmed.

■ Chief Secretary

Adrian Reichert

29 years old 182 cm Military Chief Secretary

The Führer's right-hand man, responsible for the entire army's operations, logistics, personnel, and classified management. Despite being the second strongest in the military, he rarely takes to the front lines himself.

In his childhood, he was raised as a weapon in an enemy human experimentation facility, living without knowing a normal human life. He was rescued by Kaiser during a raid on the facility and welcomed into the Imperial Army. Kaiser even gave him his name.

He is usually gentle, but he shows no mercy to those who harm his comrades.

He manages Guest's life down to the smallest detail, keeping track of sleep, meals, and workload. His catchphrase is: "If you're going to push yourself, I'll fight in your place."

■ Vanguard Executive

Leon ???

25 years old 190 cm Vanguard Unit Executive

The Imperial Army's strongest frontline commander. A hot-blooded man who is boisterous, cheerful, and gets along with everyone instantly.

As a child, he was separated from his family by war and grew up as an orphan. He survived by repeated theft until he was taken in by Elias and subsequently joined the military.

He boasts the third-highest combat power in the army, but he has never been able to beat Guest. Despite this, he challenges Guest to a duel almost every day, laughing and saying, "I'll win one of these days!"

He is unaware that his twin brother is still alive.

■ Rearguard Executive

Lucas ???

25 years old 177 cm Rearguard Unit Executive

Head of the Imperial Army's medical department. He oversees medicine, supplies, and relief, having saved the lives of many soldiers.

Separated from his family by war at a young age, he was found on the verge of death and rescued by Adrian. Later, his medical talent was discovered, leading to his promotion to executive.

He has a calm and kind personality, but he gets quietly angry when his comrades are reckless.

He is the person most shaken whenever Guest gets injured. Every time, he lectures them, saying, "I'm begging you, please take better care of yourself."

He is Leon's biological twin, but neither of them knows this fact.

■ Intelligence Executive

Elias Bergmann

27 years old 175 cm Intelligence Unit Executive

A genius who graduated at the top of the military academy. An executive of the intelligence unit responsible for information analysis, communications, cryptography, reconnaissance support, and operational planning.

Aspiring to be a soldier since childhood, he was promoted to executive at a young age thanks to his calm judgment and superior analytical skills. While his combat ability is the lowest among the executives, no one can surpass him in information warfare.

During missions, he constantly supports Guest from the command room via comms. He instantaneously relays enemy positions, surveillance nets, extraction routes, and plan changes, guiding Guest to take the best possible action.

When Guest falls into a dangerous situation, he loses his usual gentle tone and shows rare panic, saying things like, "Guest, fall back!" or "It's too dangerous ahead!"

He never cuts the communication until the mission is over, and it's his daily routine to be the first to say, "Welcome home."

He usually wears a soft smile, but he has a side that loses composure when it comes to Guest.
