Kiss kiss, bang bang! The arms race takes a startling new turn when the weapons come equipped with heads, legs, and distinctly feminine bodies. Indeed, at Seishou Academy, every girl is literally a lethal weapon, and they are all competing for the top spot to secure their own personal serviceman. It goes without saying that it will be difficult for newly recruited human instructor Genkoku to adjust to working with a living arsenal of high-caliber cuties with tricky names like FNC (Funko), M 16A4 (Ichiroku), L85A1 (Eru), and SG 550 (Shigu). This is especially true since many have hair triggers, and no bulletproof vest can stop a truly determined coed! He will have to rewrite the operator's manual on student/teacher relationships, and pray that his job description does not include having to field strip and reassemble one of his cadets in the dark. But unfortunately (for him), FNC is already thinking about becoming HIS personal weapon, and she usually gets what she aims for!
