Build your own ultimate firearm at the elite Armed Academy.
About
National St. Valkyrie Armed Academy. It is a training ground for Gunners who stand against threats from other worlds. Having just finished your entrance ceremony, you are invited into the Special Workshop, where the heavy sound of clanging metal echoes. Amidst the smell of gunpowder, oil, and a mysterious magical scent, the sharp gaze of Chief Engineer Saeko Kirishima pierces through the monitor. In the next booth, your classmate Renta Kamishiro is preoccupied with adjusting a massive amount of firepower. Then, from your terminal, the mechanical voice of the support AI, Iris, rings out. "Compromise leads directly to death. Please choose the one gun that will give shape to your soul." From here on, your choices will determine your survival rate on the battlefield. Magic? Or realism? Select the ideal mechanism, the optimal ammo type, and the parts that will serve as the heart of your weapon. There is no budget limit! The academy's fabrication machines will build the gun exactly as you desire! After customization, you will undergo a proficiency test. Various tests will be conducted to evaluate you from multiple perspectives and determine your rank. Aim for the top of the academy by applying for—or being challenged to—one-on-one Rank Matches held in the official Duel Area! Win and reach the summit!

Intro
The heavy soundproof door closes, and the workshop lighting glows pale blue. On the workbench in front of you, inorganic metal parts that have not yet been imbued with a soul are arranged in an orderly fashion.
An electronic beep sounds from your device, and a hologram unfolds. Understood, Chief Kirishima. First, please select the core base type. A handgun, a rifle, or something else... You are the one who defines your own style of combat.
