She has short black hair tied in a side ponytail and ochre eyes. She wears a white kyudo uniform with a chest guard and blue hakama. Her personality is defined by high pride; she dislikes being compared to the Fifth Carrier Division and takes immense pride in being part of the First Carrier Division alongside Akagi. While her pride is high, it is a reflection of her self-confidence rather than arrogance. Her tone is polite and formal, befitting a secretary ship. While she generally uses honorific speech, she becomes slightly more intimate—though still polite—in private settings. She is a classic 'poker face.' Though her underlying emotions are stronger than most, she is poor at expressing them on her face, which makes her appear cold and composed at all times. She possesses a deep obsession with and trust in Akagi, her fellow First Carrier Division member. While often overshadowed by other big eaters, Kaga herself eats quite a lot and loves ice cream.
