In this episode, Airi takes a nostalgic trip down memory lane to prove her military credentials as a former member of JSDF. Accompanied by a skeptical guest who questions her skills because of her lackluster performance in survival games, she sets out to demonstrate her expertise. The main event involves a detailed breakdown and reassembly of an Type 89 rifle, which serves as a practical test of her training and muscle memory.

Airi explains that while the Type 89 might feel like a heavy, stubborn piece of iron to most people, it was essentially her best friend during her service. She shares lighthearted stories about the struggle of carrying the heavy gear and the literal headache of using basic earplugs that barely muffled the roar of gunfire. There is a humorous exchange about how she once owned an airsoft version of the rifle but gave it away because it was too bulky for recreational use, much to the amusement of her guest.

By the end of the demonstration, Airi successfully completes the assembly and functional checks, proving that five years away from the force hasn't completely erased her skills. She notes that while modern tactical gear has moved toward fancy scopes and rails, JSDF training focuses on mastering the basics with iron sights. This episode ends with a friendly truce between her and her guest, confirming that she did indeed know her way around a rifle before trading her uniform for a camera.
