Noriaki Kashiwabara, known among peers as "Noripii," hails from the same hometown as Nanako Hanasaki. He serves as her designated flying partner within Cadoques High's Aerial Division "Centezual," where both train as pilot trainees, and holds nationality from the Kingdom of Qi.

Kashiwabara exhibits a highly energetic and vocally expressive demeanor, often appearing loud and enthusiastic. Narrative cues and interpersonal dynamics consistently suggest an underlying romantic interest in Nanako Hanasaki, forming a central but unresolved aspect of his relationships.

Despite a peer reputation for exceptional skill in evasive maneuvers—humorously labeled "the best at running away"—rooted in observable caution during flight operations, a significant shift occurs in Episode 11. He volunteers alongside Benjamin Sharif for a perilous high-risk reconnaissance mission, demonstrating development beyond his established fearful disposition. The mission results in severe casualties. Kashiwabara narrowly survives, though his aircraft sustains damage; specific injuries remain unspecified.
