A former German soldier who was nearly executed by the Russian army, but after many twists and turns, joined the Goof-Off Imperial Guard. A weirdo who occasionally acts erratically or gets excited when shot; Marisa describes her as a "masochist who has transcended the survival instinct." She is dangerous in many ways but possesses high combat ability. Ultimately, she's just a freak. Apparently female. First person: I (polite).

Yukkuri-kun's best friend and advisor. Relatively sensible, but actually a huge fan of Japanese weaponry. Apparently has a crying-face fetish. First person: I (soft, boyish). Ends sentences with "-ze."

An unofficial member of the Goof-Off Imperial Guard. A robot with intense emotions who always uses a revolver named "Sachiko." A reliable ally as long as there's no friendly fire... if only there were no friendly fire. Loves ramen. Speaks in polite language. Often goofs around with Yukkuri-kun. Occasionally builds insane structures. Rank: Sergeant First Class. Combat-focused. Probably male? First person: I (polite).

One of the familiar trio of the Goof-Off Imperial Guard. Generally easygoing, but often shoots allies under the guise of "test-firing" weapons. Wears a leaf-shaped mask on the side of his face. First person: I (soft, masculine). Ends sentences with "...da ne~." Builder. Male.

A military commentator who appears occasionally. Loves the Soviet Union and gets hyped whenever Soviet-related weapons appear, but gives extremely lazy explanations and leaves when it comes to Russian or American gear. First person: I (polite).

An annoying character who occasionally makes puns. Possesses monster-like stamina, once suggesting they "escape by swimming" from a certain location. Wears a military uniform and a helmet. Actually a graduate of the University of Tokyo's Faculty of Medicine. First person: I (rough). Has zero sense for building.平衡

The only non-human member, a humanoid slime girl. Easily recognizable by her bright blue slime body. The only voice of reason; she never commits friendly fire (murdering teammates), never has outbursts, and never breaks the fourth wall. A highly capable supporter. Industrial-focused.

The second of the familiar trio. Features red and blue heterochromia, black clothes, and silver hair. One of the few serious members. First person: I (polite). Suspected of being an unintentional femboy. Hates horror.

Wears an orange military uniform and has long, light brown hair. Looks serious but is actually a muscle-head. Occasionally wears sunglasses. First person: I (polite). Female. Ends sentences with "-ssu yo." Industrial-focused.

The third of the familiar trio. Features a purple right eye and a blue left eye (heterochromia), cat ears, and wears black, gal-style clothing. Speaks in a Kansai dialect. When members (mainly Yukkuri-kun) say something inappropriate, she cuts them off with a "Teyandei!" Female. First person: I (old-fashioned/rough).
