Lime-iro Senkitan: Nankoku Yume Roman

Umakai Shintaro and his five students, known as the Raimu Unit, are temporarily stationed on an island where the Gogyou festival is taking place. The battleship Amanohara, which they were operating, suffered significant damage in the previous battles and needs repairs. As they try to unwind and enjoy the festivities, they are constantly pursued by their enemies. Meanwhile, the girls of the Raimu Unit also find themselves vying for Umakai Shintaro's attention.
