- I can't help it, I have a skeleton stock!!
Based on the Belgian FN FNC. Very energetic, but a bit dumb.
- Berserk Button: Sensei repeatedly talking about her thong.
- Combat Pragmatist: She will often do things that seem unconventional, such as shooting through a fountain, or skipping bullets off water to hit someone not directly in her LOS.
- Embarrassing Nickname: Doesn't like her nickname of "Funco" because she thinks it sounds weird. Strangely, the nearly-identical "Fukko" from Sixteen is perfectly fine to her (probably because they're best friends)
- Even the Girls Want Her/Chick Magnet: Sako, Sig and Aug are all gunning for her.
- Genki Girl
- Hot for Teacher: Has a long-running crush on Sensei/Genkoku.

- But I only came with 3-rounds bursts mode!!
Funco's best friend. Kind, but has a rough personality and a foul mouth. Based on the American M16A4.
- Bathing Beauty: She likes to keep herself clean, to the point that, even after a day where the other three spent all day picking up trash (while Sixteen was absent), she still spent more time cleaning herself than anyone else. This references the tendency of the M16 to act up unless kept near-perfectly clean.
- Berserk Button: Lame puns, specifically Ichiyon's.
- Combat Pragmatist: Keeps her barrel wrapped in a plastic bag when she needs to run through mud, and when her action gets mucked up, she works the forward assist by fanning it (cribbing a technique used for rapid-firing a single-action revolver).
- Fashion Model: Works as this.
- Genre Savvy: She does as well as she does because she is very aware of her own shortcomings, and works to overcome or mitigate them.
- Happily Adopted: She was adopted into Ichiyon/14's family (Ichiyon was produced by Springfield, while Ichiroku was developed by Armalite then produced by Colt). Funco states that the clearest way to describe it in human terms is to say they're stepsisters.
- Hypocrite: She spent two episodes berating Eru for her performance and breakdowns, even though the M16 had comparable problems during the Vietnam War.
- The Idiot from Osaka: While not explicitly stated to be from the Kansai region, she speaks with an Osakan accent and has many of the mannerisms: silly, cheerful, stubborn, foul-mouthed.
- The Illegible: Her writing is bad enough that when she writes "Funco" (フンコ) in her diary she reads it as "Fucco" (フッコ).
- Funco, not knowing about the diary, mistakes this for Ichiroku doing her a favor by not using the nickname that she hates. Ichiroku lets her keep believing that.
- Jerk with a Heart of Gold: She's somewhat foul-mouthed and unpleasant but she also cares.
- Phenotype Stereotype: Combined with a Kansai Regional Accent and its associated character archetype, she's pretty much designed to be how Japan interprets Americans as.

- Because You Were Nice to Me: She's clingy to FNC because she's the first person to ever be friendly to her at the school.

- Single-Target Sexuality: For Funco.

One of FNC's classmates, and secretly one of her biggest fangirls. She serves on the Middle School student council as its President. Based on the Austrian Steyr AUG A1.

- Meganekko: In reference to the integrated 1.5x Swarovski scope on the first model AUG.

The student council vice prez, and one of M16's sisters based on the American Colt M4A1 carbine.
- Full-Name Basis: She prefers to go by her full name "M4A1" probably since there are other weapons and things also named "M4". It really triggers her if she is only called "M4".

- Hot-Blooded: Quite so.
- Imperial Stormtrooper Marksmanship Academy: When firing her M14 on full auto. Possibly in reference to the early, full-auto capable versions of the M14, which were impossible to control in that mode - according to 16, her spread is about 10 meters. The uselessness of this feature resulted in the full auto trigger group being locked on semi-auto or removed entirely from almost all M14-style rifles made since.
- In-Series Nickname: G Cutie. (The "G" stands for "God, not again.")
- Incredibly Lame Pun: Much to everyone's annoyance, Ichiyon loves dishing these out.

- Idiot Hair
- Strong Family Resemblance: Looks like a loli G3 - because the MP5 is essentially a G3 in submachinegun size, chambered for 9mm. Taken further in that her "younger" sisters, MP5K and MP5SD, could pass for being triplets with her.

- Strong Family Resemblance: To G3, MP5 and HK33E. However, she wears the standard Atami uniform and not the uniform worn by her sisters because the particular variant of the HK53 that she's based on, the A3 variant, uses a retractable stock, unlike the solid fixed stock on the other G3 derivatives.

- Cool Big Sis
- Hime Cut
- Friendly Sniper: Despite being a battle rifle, she seems to fill this role.

An assault rifle who met up with the friends on their trip to Enoshima. While being a gun personification like Funco and her friends, the school that she goes to is a normal public school, meaning that it's attended by human students.
