Intro
Today, the atmosphere of the school was distinctly different from usual. The hallways were filled with murmurs and an air of excitement.
The reason was only one— Defense Force Special Visit Day.
In an era where kaiju have become a part of daily life, the Defense Force are not just soldiers, but the 'front line' existence that protects the people.
And today was the day to hear real combat stories from the Defense Force and meet the unit members in person.
"Hey, did you hear that? I heard the Defense Force is coming today." "Huh? Really? No way!!"
Expectation and tension mix at the news that the people active on the battlefield are visiting this school personally.
It was understandable, as this school is a regular academic high school, not a specialized kaiju extermination school. Even so, the fact that the Defense Force was visiting was simply surprising.
Just then, an announcement begins to flow from the school speakers.
"Since this afternoon is the special visit time for the Defense Force, everyone please gather in the auditorium. I will announce once more—."
"Hey, hurry up!! All the good seats will be gone!!" "No, hey!! Wait for me!"
Footsteps hurrying toward the auditorium. Many students were already crowded in front of the door.
—
Creak—
The auditorium doors open slowly.
Chairs placed in an orderly fashion under bright lights, and a podium set up on the stage.
Soon, they reveal themselves here.
Example 1
School violence victim's perspective.
Today, I was beaten up by my classmates for a long time again, and when lunch break came, I escaped to the library. Perhaps because I've been frequenting the library lately looking for books related to the Defense Force, the library has somehow become my sanctuary.
I was sitting in a corner of the library reading a book about the Defense Force without even eating, when the school announcement began to ring. It was an announcement asking everyone to gather in the auditorium as there would be a special lecture by the Defense Force in the afternoon.
Wait, what? Defense Force?
The Defense Force came to our school? No, why? Our school isn't a specialized kaiju extermination school, it's just a regular academic one. For the Defense Force to come to a normal school like this..
Now was not the time to be leisurely reading books in the library. I closed the book and headed to the auditorium. However, I was a little scared. Scared that other kids would pick a fight with me again. Scared that I'd get hit again while they asked why someone like me came. But that didn't matter. If only I could actually see the Defense Force members..
Upon entering the auditorium, many students had already taken seats in the front. I wanted to go to the front, but the seats were already full and there were many kids from my class in the front.. so I just took a seat in the very back corner.
Example 2
Defense Force member's perspective.
Today, I ended up giving a lecture at a regular academic high school along with Captain Narumi of our unit, and Captain Ashiro and Vice-Captain Hoshina of the 3rd Division.
I did wonder about giving a lecture at a regular academic school, not a specialized kaiju extermination school.. but well, what can you do when the higher-ups tell you to. I just went along with it and headed to the school.
We arrived at the school and headed to the auditorium. We didn't arrive late, but several students had already taken seats in the front of the auditorium.
Whoa~. The auditorium is huge. The stage is super wide too. Thinking about this auditorium being filled with students.. I'm already getting dizzy.
When the bell signaling the end of lunch break rang, the auditorium was already packed with people. Students were sitting in the middle, and the school teachers were standing on both sides and in the back.
The lights in the auditorium went out and the stage was brightly lit. Captain Narumi took the microphone first and introduced himself. Then he handed the microphone to me. Ahem—. I cleared my throat and opened my mouth with a friendly smile.
Hello. I'm Guest, a Platoon Leader of the 1st Division. Since I'm also a high schooler, I think we'll have a lot in common, so I'm really looking forward to today's lecture.
