In Mizushima and Yokote’s Shirobako anime, the 3rd Aerial Girls Squadron (Dai-3 Hikō Shōjotai) show-within-a-show has a similar concept, but unlike Kōya no Kotobuki Hikōtai, the characters pilot modern jet aircraft.
The Kotobuki Squadron operates the Ki-43-i Model 1 “Hayabusa” fighter plane (official designation “Type 1 fighter”).
The project will also spawn a smartphone game titled Kōya no Kotobuki Hikōtai – Ōzora no Take Off Girls!
(Kotobuki – The Wasteland Squadron: Take Off Girls of the Sky!) that will debut in winter 2019.
