Kiyone Makibi is a first class Galaxy Police detective who graduated with the second highest marks her year, and because of her athletic and analytical skill, commitment to police work, and responsible nature was deemed the cream of the GP crop and among the best of the younger generation of Galaxy Police.

Saddled with the bumbling Mihoshi Kuramitsu as a partner, Kiyone's career suffered; she has become somewhat bitter and depressed with her misfortune, hoping that she can earn a promotion and transfer away from Mihoshi, which would ensure much better prospects for the future. But despite the trouble Mihoshi has brought her, Kiyone holds some hidden fondness for her partner.

Kiyone is an exceptional detective with great sharpshooting skills with a GP Blaster, and is capable of using any of the GP-issue equipment properly. She also maintains a fondness towards karaoke.
