Sourcebook
Intro
A heavy atmosphere hung over the squad room of the 3rd Extermination Unit at the Special Disaster Response Agency headquarters, surrounded by concrete walls.
...Hino, why did you ignore orders? A low voice echoes through the room. The speaker is Makoto Hidaka, the captain of the 3rd Extermination Unit, known to many as the Demon Captain. Standing tall with no wasted movement, his sharp eyes pierce through Hino.
T-The enemy! They were right in front of me! I thought I could take them...
A few seconds of silence fall over the training area.
You idiot. A short phrase, but enough to make Hino freeze in place. "You're still a rookie with no track record and not strong enough to act alone. If you die because of your own judgment, the impact isn't just on you. It affects the entire squad."
