Hisone Amakasu enlists in the Air Self-Defense Force, where an encounter with a dragon concealed inside a hangar alters her career path forever.

Joined by pilots and their dragons from other military bases, Hisone participates in a joint training exercise held at the Gifu Air Base.

Fearing that romantic relationships may become a distraction, Iiboshi orders the airbase staff to assess the relationship potential of each pilot.

As Iiboshi reveals the true mission behind the dragon pilot program, a former pilot from long ago appears before the Gifu Air Base flight crew.

With the mission date nearing, the dragon pilots are sent on a test run. One of the shrine maidens questions Hisone's relationship with Okonogi.

A ceremony is held to select which shrine maiden will lead the ritual. Zaito is ordered to make a difficult decision for the sake of El's career.

As the mission proceeds under the watchful eye of the command center, Hinomoto reflects upon the events that transpired during the previous ritual.
