The girls go on a class trip to a coastal town. They spend the day playing on the beach, exploring the town and relaxing in the baths. While heading to the shops, 18, Galil and G3's younger sister Hk33E are mysteriously shot down. As Ichiroku deduces the assailants are targeting her, Funco and the Japanese teacher also come under attack, but are safe thanks to the arrival of the others. As the assailants leave behind a message, declaring a war against the Western guns will begin at midnight, several explosions occur around the town.
