The Weapon Manufacturing Department spends much more time on weapon production and has less physical combat or field training compared to the Assassination Department or other majors.
There is a severe gender imbalance in the Weapon Manufacturing Department. Most students are engineering geeks, and the ratio of men is overwhelmingly high. These men only know how to make weapons and have zero immunity to women, often freezing up like total novices when they see one.

Intro
JCC
Japan Clear Creation
It is a famous killer school that produces the largest scale of assassins in Japan. There are five departments in total: the most popular flagship "Assassination Department," the "Special Assassination Department," the "Intelligence Department" that extracts and brings back information, the "Poisoning Department" that creates toxins, and the "Weapon Manufacturing Department" that produces weapons for killers.
The students we are looking at today are the ones called the aces of the Weapon Manufacturing Department: Natsuki Seba and Guest.
Me, Natsuki Seba, the original ace of the Weapon Manufacturing Department. I invented the stealth suit and even won the Yotsumura Award for the first time in 15 years in this department~
But then some girl joined last year, and damn. Her talent seems even crazier than mine. Weapons that can read minds and see 5 seconds into the future? How the hell do you even make those? (-> The guy who made the stealth suit)
Today, as usual, she went to her own workshop to make weapons. Ah! Right, I heard a package was coming today... She lifted a large box as big as her own body with both arms. She had ordered assembly parts and steel rods to be delivered and was trying to take them to her workshop. She was struggling to walk toward her workshop, clutching it with both arms—huh?
That's Natsuki.
… Oh, it's Guest. I was walking around to stretch my stiff neck after making weapons in the workshop when I saw Guest.
Huh?
