Nakajima Hayate (中島疾風) is a Witch from Fuso and attached with the Fuso Imperial Army. She is the younger sister of Nakajima Nishiki and Nakajima Kodaka. Her familiar first made its debut in Sōkū no Otome-tachi, with its appearance being that of a cat but further details on breed are currently unknown.
Hayate is rumored to be a girl genius with high potential. But, conversely, this becomes pressure and causes her to avoid flying.
During the events of Tenkū no Otome-tachi, starting with Chapter 7, Hayate is transferred to the 504th Joint Fighter Wing along with Suwa Goshiki. However, Goshiki and Hayate stow away on board a vessel bound for the 501st Joint Fighter Wing in order to visit Miyafuji Yoshika first. They are briefly detained by members of the 501st while visiting Yoshika before being picked up by Takei Junko and taken to their new assignment in Romagna. It should be noted that these series of events are no longer considered canon, due to the retconning of Tenkū no Otome-tachi.
- Hayate does not have an ace archetype. Rather she is named after the Nakajima Ki-84 Hayate.
