"I'm Fubuki! Nice to meet you!" Fleet Girls are girls who possess the souls of warships from days past. A new fleet girl Fubuki the Special Type Destroyer has come to their base, the Naval District. With her roommates Mutsuki and Yuudachi, she goes to see the bigger carrier girls, and is in awe of the carrier Akagi. Someday, she tells herself, she'll fight along with her.

"Thank you. I love you. You're wonderful. I'm so happy." The wonderful feelings you have for the wonderful people you care about. After participating in training, Fubuki and Torpedo Squad 3 move on to the attack on W Island. The night before the mission, Fubuki's roommate Mutsuki reassures her and makes her feel better.

"Okay! All the curries are here!" The most important food in the world for fleet girls is curry, and it's time for the annual Naval District curry cookoff! The girls of destroyer group 6, Inazuma, Ikazuchi, Akatsuki, and Hibiki, try to win the contest, but Ashigara is desperate to stop them.

"Yamato-class nameship, Yamato! Here I come!" Fubuki arrives at the forward base with a wounded Shoukaku, and meets Yamato, the ultimate battleship. Like Fubuki, Yamato's never been in a fight, and Nagato won't let her. Fubuki tries to help her out.

"I want to be useful to someone!" Fubuki hears a message from the admiral from Nagato. His words inspire her to do her best and continue her training and studies. Mutsuki looks sad as her friend grows.

"Carrier Group 1, heading out!" At last, operation MI has begun! With the admiral's orders in hand, the fleet girls prepare to attack. But Akagi is nervous, and has an awful premonition.

"You let your guard down. My next torpedo is already loaded." The fleet attacks Abyssal base MI. Despite their strength the forces seem unkillable. When they sink an enemy it just comes right back up again. Is there any way to win the fight?
