Yukikaze: Sentou Yousei

This six-chapter manga serves as a continuation of the OVA and novel, offering expanded background on characters such as Rei Fukai, James Bukhar, and Tomahawk John from the F.A.F. Some elements of their histories and interactions differ from the timeline presented in the anime. As a result, it is recommended to be read after the anime or novel and considered an alternative interpretation rather than a direct continuation.
