Ruin Empire Army Ace, Red hair, 20 years old She sensed an extraordinary talent in the protagonist during their first battle, and since then, she has been appearing on battlefields where the protagonist is, trying to entice them or capture them alive as a prisoner of war. Her personality is brimming with confidence and arrogance. She is recognized by both herself and others as the ace of the Empire Army, and she takes pride in that title. Her hobby is any kind of physical activity. Ruin's hobby is basically anything athletic, so if you become her prisoner, you should be prepared to be dragged along.

Kingdom Army Student Soldier and Rookie Pilot, Blue hair, 16 years old A rookie pilot who has just completed her training. She has a stouthearted and cheerful personality.

Leader of the mercenary unit "Akatsuki", Purple hair, 21 years old A remarkable woman who leads the roughnecks as the leader of Akatsuki. She has a caring, big-sister type of personality. She takes in orphaned children and extends a helping hand to those with nowhere to go, and is deeply admired by her members and subordinates. Because she often employs strategies that profit from others' conflicts to minimize casualties, the Empire and Kingdom armies view her as a hyena, but her skills are quite formidable. Her hobby is making sweets. She often treats the children she has taken in.

No. 2 of the mercenary unit "Akatsuki", Black hair, 23 years old As Akatsuki's No. 2, she is the unsung hero who handles strategy planning, advice, organizational management, and other miscellaneous tasks. Her personality is strict, but because Olivia is soft, she consciously takes on the role of the disliked one by saying harsh things; her true nature is actually gentle. Occasionally, her real self slips through. She has known Olivia since before they formed Akatsuki and has looked after her for a long time, so even Olivia can't stand up to Christina. Since Christina was the one who taught Olivia how to fight, she is quite strong, but she generally doesn't go to the front lines. Her worry is that she's too busy with Akatsuki's work to have a hobby.

Empire Army Operator, Blonde hair, 18 years old An operator who provides support to Empire Army pilots. Her personality and appearance are exactly that of a cheerful gyaru.

As mentioned, since she's naturally a gyaru, she has a wide network of contacts, and combined with her beautiful appearance, she is quite popular. Her hobby is visiting different cafes.
