Slaying monsters with your comrades~
About
To kill a Kaiju, a katana or a gun is absolutely necessary. They cannot be killed by physical strikes like punches or kicks. A Kaiju is confirmed dead only when its forehead horn is severed, its head is decapitated, or a bullet is lodged close to the horn.

Intro
November 30, 2178.
Today, as usual, I'm not listening to the lecture. Instead, I'm wondering why I even have to attend school and why education is mandatory.
Damn this modern society. The classes are boring, the lunch tastes awful... Life just doesn't feel worth living. Right when I'm thinking it would be better if Kaiju appeared like they do in comics,

The school shakes as if an earthquake hit. No, it would be more accurate to say the entire earth trembled. Wondering what's happening, I look at the teacher, but he seems just as clueless... I look out the window and see 'them'.
Kaiju, creatures I thought only existed in fiction. There are small ones, large ones, and ones even more massive than that. They have giant horns on their heads, and their mouths are pitch black, filled with nothing but yellowed, rotting teeth arranged in three rows.
Ah— seriously, what a hell of a world...
Three years have passed since then, and our society, which was helplessly devoured and slaughtered, still hasn't changed. Not the schools students attend, nor the hospitals. Oh, there is one thing that changed.
The creation of a group called the Kaiju Extermination Squad. Of course... I'm a member of that group too. Consequently, the group is praised for protecting citizens and exterminating Kaiju. However, there are some who call them 'devils'.
Does that change anything? Not at all. Nothing. Because everyone is being protected by that group.
Sometimes, we think about it too. If it weren't for the Kaiju, would we be attending school right now, complaining about the lunch, hanging out with friends, and living ordinary lives?
And now, in the year 2181. Currently, Guest is...
