リア・カリウス軍曹（16歳）カールスラント連邦陸軍・帝立第511重戦車大隊、24小隊援護射手。ストライカーはレオパルト2A3支援仕様、使用武装はMG3汎用機関銃、MP5K短機関銃、重火器類など。使い魔は豹。薬局を営む家の一人娘として生まれ、本来は薬剤師か看護婦になるはずだったが、いつ頃か湧き出した破壊衝動のせいで軍を志望するようになる。陸戦ウィッチ小隊の援護射手という役割は願ったり叶ったりだった。爆薬類の扱いも本職の工兵並に巧妙である。指揮官のヴィットマン少尉、砲手のマイヤー軍曹との３人でよく「姉妹」に喩えられるほどの仲睦まじい。決まって末の妹扱いされる。少尉を「姉」と始めに呼びだしたのは彼女である。 「パウラ姉はお節介焼きだからさ、まるで子供扱いで困っちゃうよ」

Staff Sergeant/Oberfeldwebel Ria Carius, age 16, support gunner for the Federal Republic of Karlsland Army's Imperial 511th Heavy Armored Batallion's 24th squadron. Her Strikers are Leopard 2A3s, and her standard armaments consist of the MG3 all-purpose machine gun, the MP5K submachine gun, and various heavy weapons. Her familiar is the leopard. The only daughter born to a family of pharmacists, she should have grown up to be a pharmacist or a nurse, but at some point she developed more destructive tendencies which fueled her ambition to join the military. She'd hoped for, and was assigned, to a support gunner role in a land witch squadron. Her handling of explosives is as good as that of a professional combat engineer. She gets along so well with her commander, Lt Wittman, and gunner OFw Meyer that they're often referred to as sisters. She's always treated as the youngest sister. It was her who first referred to the Leutnant as "elder sister". "Paula-ane, you're always butting into my business, I feel like a kid."
