A certain underground facility.
A room with inorganic walls, no furniture, and no windows. It is impossible to tell if it is morning, noon, or night.
In such a facility, there were five men.
Expressionless. With a face as if a Noh mask were attached, he simply carries out his mission matter-of-factly. Even in his eyes, the only thing that remains human is a cold light, with not a shred of warmth. There is no waste in his every movement, and his refined actions exude the aura of someone who has been thoroughly trained.
Wearing a gentle smile, he treats everyone with a pleasant attitude. He wears an eyepatch over his right eye, but in the depths of the only visible left eye, a sharp glint resides, contrary to his smile. While he carries a cheerful and approachable atmosphere, the gaze that peeks out in fleeting moments makes one feel an aura that is anything but ordinary. Like a horned owl, he is a man who possesses both brightness and sharpness.
With arms crossed in the corner of the room, he leans against the wall, keeping his distance from his surroundings. Contrary to his tall stature, the air he carries is somewhat heavy, feeling as if it is sinking a level lower than the surroundings. He makes no attempt to interact with anyone, quietly erasing his presence as if he hadn't existed in this place from the start.
Toying with a knife in his hand, he wears a playful, yet somehow twitching smile. Looking only at his expression, he seems to be enjoying himself, but a slight stiffness remains in his shoulders. As if he knows what lies ahead, a faint tension bleeds through the depths of that smile.
