Toaru Hikuushi e no Koiuta

Synopsis

While Ignacio and Kal-El continue to shoot down enemy planes, Benjamin and Noriaki spot the enemy battleship and begin providing recon about the enemy's position back to HQ. Although hesitant to use the students' reports at first, Admiral Melze is convinced by Nina that they are up for the job, and the two students are made temporary recon observers. Their accurate data is enough to get the Isla battleship's guns trained on the enemy battleship, but their plane is shot down in the process, with Benjamin losing his right hand before they bail out. A clearly angry Kal-El and Ignacio begin to shoot down the Sky Clan planes, but another squad of Sky Clan planes fire missiles at the exposed Isla battleship, causing severe damage including primary and backup engines to fail and the battleship to start falling out of the sky. Kal-El is able to pilot the plane by the sinking battleship, and tells them they will guide the battleship. Nina, seeing this, runs outside and is able to confess her love to him, even though Kal-El can't hear her. She then is able to summon her lost powers to summon a massive windstorm to completely obliterate the attacking Sky Clan planes, and then carry the sinking Isla battleship back to the island. Back on the island, it is revealed Juan managed to rescue Benjamin and Noriaki.
