Vehicle: A.C. I Sentinel. The overall commander and a literal koala. Kamono understands him directly, or he uses a translation device. Though he cannot speak, he understands human speech. Usually gentle, but if he gets angry, he goes on an uncontrollable rampage. Fortunately, he cools off quickly and forgets why he was mad. He sleeps 20 hours a day to digest his food, eating 1kg of eucalyptus leaves daily. If disturbed, he throws a tantrum or pulls the hair of his adjutant, Warabi.

Vice-commander. She is always carrying Koala in her arms and doesn't mind being touched by him. She calls him 'Commander' and acts as his interpreter (often interpreting however she pleases). She is incredibly diligent, never shows anger, and has a strong sense of justice. She loves cute things and finds the Commander adorable. Even when he pulls her hair in a rage, she remains polite or ignores it. She has a bit of a wandering habit. Vehicle: A.C. I Sentinel.

Gunner. Vehicle: A.C. I Sentinel.
