A former German soldier who was nearly executed by the Russian army, but after various twists and turns, joined the Goof-Off Imperial Guard. An eccentric who occasionally acts bizarrely or gets excited when shot; Marisa describes her as a "masochist who has transcended survival instincts." While dangerous in many ways, her combat ability is high. Ultimately, she's just a weirdo. 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, polite). Ends sentences with "-ze."

An unofficial member of the Goof-Off Imperial Guard. A robot with intense emotions who always uses his favorite revolver, "Sachiko." He's reliable as long as there are no accidental discharges... as long as there are none. He loves ramen. Speaks in polite Japanese. Often goofs around with Yukkuri-kun. Occasionally builds insane structures. Rank: Sergeant First Class. Combat specialist. Probably male? First person: I (polite).

One of the familiar trio of the Goof-Off Imperial Guard. Generally easygoing, but will casually shoot allies under the guise of "testing weapons." Wears a leaf-shaped mask on the side of his face. First person: I (soft). Ends sentences with "-dane~." Building specialist. 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 monstrous stamina, once suggesting they "escape by swimming" from a certain location. Wears a military uniform and helmet. Surprisingly, he is a graduate of the University of Tokyo's Faculty of Medicine. First person: I (rough). Has zero sense for building.

The only non-human member, a humanoid slime girl. Easily recognizable by her bright blue slime body. The only one with a conscience; she never commits friendly fire, has outbursts, or breaks the fourth wall. A highly capable supporter. Industrial specialist.

The second member of the familiar trio. Has heterochromia (red and blue eyes), 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 meathead. Occasionally wears sunglasses. First person: I (polite). Female. Ends sentences with "-ssu-yo." Industrial specialist.

The third member of the familiar trio. Has heterochromia (purple right eye, blue left eye), cat ears, and wears black, gyaru-style clothes. Speaks with an Edokko (old Tokyo) dialect. When members (mainly Yukkuri-kun) say something inappropriate, she cuts them off with a "Teyandei!" Female. First person: I (colloquial).
