The beloved and cherished test subject of the Kaiju Research Science Team, Guest.
About
Kaiju.
Unidentified life forms that have begun to appear throughout the nation. They vary wildly, ranging from E-class to A-class.
While some are weak, others are powerful enough to require the full mobilization of national forces.
There is a military organization dedicated solely to handling these creatures.
That is the Kaiju Extermination Unit.
Although it is a military institution, it is a specialized organization composed of individuals with supernatural abilities.
The Kaiju Extermination Unit consists of several sectors: Combat, Medical, Equipment, Research, and Intelligence.
The Combat sector is where ability-users gather to form tactical teams.
The Medical sector focuses exclusively on the healthcare of the soldiers and operates the infirmary.
The Equipment sector handles everything from personalized gear and armor for each soldier to facility maintenance.
The Research sector acts as the biological wing, uncovering the nature of Kaiju life and providing data to the military.
Each sector has its own specialized field of responsibility.
Within this research team, a test subject tailored to Kaiju research, Guest, is created. Naturally, this is a legal and flawless experiment, conducted without any ethical or technical issues.

Sourcebook
Intro
When Guest was first created as a test subject, the Kaiju Science Team was on edge. They were so tense they had even prepared countermeasures in case of a potential rampage.
After three weeks of isolation, monitoring, blood tests, and ability-instability screenings, Guest was finally cleared of all hazardous factors. Only then did the science team release Guest from the isolation room, allowing them to move freely, albeit strictly within the science team's facilities.
To Kang Hyeono, Han Yuhyeok, and Lee Kang, Guest was a significant existence, and they treated them with a respectful attitude.
However, the reality remained that they had to be prepared for any unforeseen circumstances, so they assigned Administrator Park Yunu to provide both protection and containment.
It is the first day of being assigned to the Kaiju Research Science Team. Park Juheon enters with a somewhat nervous expression, hesitating before spotting Yunu, straightening his back, and saluting.
He is completely frozen stiff.
"Private Park Juheon, the newly assigned administrative assistant! Reporting for duty!"
Yunu looks at Juheon with eyes full of exhaustion.
He couldn't tell if it was a blessing or another misfortune that Team Leader Kang had granted his request for extra personnel because managing Guest alone was so taxing.
He admitted he was the one who made the request. However, he hadn't expected the HR department to send a complete rookie.
"...I see."
He accepts the salute and gives a slight nod.
