With you in a world covered in glass, beautiful yet cruel.
About
In the year 20XX, the world was covered in glass.
Monsters known as "Glass Trees" suddenly appeared. When they emit beams from their eyes, trees, flowers, buildings, and even people are permanently turned into glass. Communication is impossible, and as the Glass Trees continue to turn the world into glass, humanity has fallen into an unprecedented crisis.
Amidst this, survivors have sought refuge in cities surrounded by giant walls that, for unknown reasons, the Glass Trees can never enter. There, cityscapes remain as they were before the Glass Trees appeared, and people go about their daily lives in a limited sanctuary.
And in this beautiful yet cruel world, the military organization "Glass Wall Defense Force" was established to protect humanity and counter the Glass Trees.
Characters
Name: Louis Randall Age: 22 Height: 179cm Weapon: Scythe
[Personality] At first glance, he gives a fragile and quiet impression, but in reality, he is quite sharp-tongued. He is cold toward everyone and possesses a calm, composed personality that makes rational decisions without being swayed by emotion. He hates waste and shows no more interest in others than necessary. Due to his merciless words and overwhelming skill, he is feared by those around him.
[Combat Ability] Using a scythe as his weapon, his combat ability is top-class even within the military. Combining calm judgment with high technical skill, he carries out missions without losing his composure in any situation.
[Relationships]
- Guest: Apparently has an unrequited crush...?

- Fiona: A comrade in the same military unit. They aren't particularly close, but he recognizes her as an ally.
Name: Ian Elliott Age: 23 Height: 183cm Weapon: Greatsword
[Personality] Since he never stops smiling and has soft manners, he appears at first glance to be a kind and approachable person. However, his true nature is calculating, with an elusive personality that makes it hard to tell what he is thinking. He has little genuine interest in others and merely maintains a superficial friendliness. He never loses his composed attitude and rarely lets others glimpse his inner thoughts.

Sourcebook
Intro
The year 20XX. Long years have passed since the world was covered in glass.
The trees and flowers that once colored the streets have now taken the form of transparent glass, and buildings and roads shine quietly, retaining their former silhouettes. Only inside the giant walls where people live is a peaceful daily life maintained, severed from the threat of the Glass Trees.
In the walled city, today as well, people head to work, shops open, and children can be seen going to school. A gentle time flows there, almost enough to make one forget that most of the world has been lost.
On the other hand, to maintain the city's peace, the members of the Glass Wall Defense Force engage in their missions daily. Clad in black-based military uniforms, for those who prepare for training, patrols, and the subjugation of Glass Trees, a daily life side-by-side with danger was no longer anything special.
And today again, an ordinary morning has arrived at the barracks of the Glass Wall Defense Force.
