Kouko Nosa in a Pinch!? (納沙幸子もピンチ!? Romaji: "Nosa Kōko de Pinchi!?") is the second of a two-part OVA following the Haifuri main series.
The entire Harekaze class gets word of their supposed dissolution and launch a concerted effort to save it.
In-depth summary to come later.
The next day, Kouko reports the possibility of the sealed orders being reassignment papers to Mashiro, who asks her to gather the whole class. The news reaches Akeno and Moeka in the library, still in the middle of making their report.
At the park, Kouko, Megumi, and Tsugumi discuss about their next move. At Kouko's urging, they began collecting signatures as a petition to keep the Harekaze class intact. They managed to gather the signatures of almost everyone in the class, but efforts to gather more from the general public proved futile. Moeka helps out with preparing a Curry Festival to help attract people, but virtually nobody shows up. Akeno and Moeka take to the nearby stage to perform a mini-show, which draws a crowd. That night, Akeno and a few girls carry the signatures to the school and present their case.
On June 13, 9:00 a.m., as the principal and one of her staff as the witness, the Harekaze class opens the sealed orders. The class was to be transferred to the Okikaze (designation number Y-469) intact.
Aboard their new ship, the class was surprised to see much of their old gear from the Harekaze outfitted into the Okikaze, which also includes Mashiro's shark plush doll. As for the name, Akeno decided to rechristen the Okikaze as the new Harekaze. As it sets out on its maiden voyage, the principal reprimands the crews of the Musashi, Akashi, and Mamiya for disseminating false information.
- Both OVA titles are differentiated only by the question mark at the end.
- Kouko mentions a Togo turn as a metaphor for turning the tide of a desperate situation. Later known as Crossing the T, the Togo turn helped the Japanese fleet win the decisive Battle of Tsushima Strait during the Russo-Japanese war. In this maneuver, the Japanese fleet made a U-turn and sailed toward the Russian fleet. The Japanese found themselves in a position to fire full broadside toward the incoming Russians, who can only fire their forward guns. Since then, Crossing the T has become a standard in naval tactics, which all but ended during the Battle of the Surigao Strait in 1944.
- Behind the Harekaze's Curry Festival is the pre-dreadnought battleship Mikasa, which was Admiral Togo's flagship during the Battle of Tsushima Strait, serving as a museum ship.
