This appearance belies a former private's unbalanced K-cup figure when she takes off her combat uniform. She possesses boundless energy from real-world military training. (Sexually, this is followed by unrelated content about a female AV actress named Amane Ryuna, and her EBWH-297.)

Amane Runa, 20 years old. 145cm tall, K-cup. Former Private First Class in a certain unit. The girl with the largest breasts in military history. She turns mission locations into battlefields of pleasure, challenging new missions with her own body. Her honed muscles and mental strength are fully utilized in battles called SEX. Her strong torso withstands the piston-like movements, and her hips sway like a counterattack, incredibly sensual. Then, the moment the restraints are released, the gushing waves erupt like machine gun fire, soaking the bed and the strong men, instantly reloading for the next round. Her unbalanced K-cup, hidden by her equipment, becomes incredibly dynamic after being shaken and kneaded. Her body, trained with real gunfire, has inexhaustible sexual desire, no matter how many orgasms she has. Unstoppable. This busty battle girl's SEX is intense!
