Kuromaru Manpuku is a supporting character in Kandagawa Jet Girls who acts as the shooter for the jet racing team Dress, working in tandem with her partner Kaguya Shinjūin. Her family has served the Shinjūin household as shinobi for generations, a tradition Kuromaru carries forward as both a devoted maid and a loyal guardian. She has thigh-length pink hair styled in low pigtails secured with yellow bows, light green eyes, and a curvy build. Her usual outfit is a maid uniform with white frills and an apron, reflecting her domestic role.

Kuromaru’s personality is energetic and eager, especially when it comes to competitive jet races. She is excitable and approaches challenges with a cheerful, can-do attitude. Yet beneath that lively exterior lies a fiercely protective streak aimed solely at Kaguya. As her maid and close friend, Kuromaru is profoundly dedicated to supporting Kaguya’s wellbeing and success, always ready to step in to defend or assist her. This unwavering loyalty defines her motivations: everything she does is for Kaguya’s sake.

Her shinobi heritage lends her a distinct edge in competition. Although specific ninja arts are not extensively on display, her background implies heightened reflexes and precision that serve her well as a shooter, making her a reliable markswoman during races. Throughout the story, Kuromaru remains a steady, supportive presence. She does not undergo major transformation because her steadfast devotion is already fully formed; instead, she continues to boost Kaguya’s ambitions and ensure their partnership runs smoothly. Her blend of spirited enthusiasm and unshakeable protectiveness cements her place as an integral member of team Dress.
