In order to fulfill the agreement a year ago, Natsumi Edo (Kyoko Fangen) and Takichang (Koshi Honda) decided to see the fireflies.But suddenly being summoned, Takimasaki and Fukami Ryunosuke (Yuta Kokawa) set out for the ship together.The storm continued on the sea, and the warships swayed violently, Takimasa and Fukakumi were involved..

On the other hand, as the navy's wife, Xia Mei, who wanted to protect her family, was restless because of the situation of the warship.Xia Mei thought about going to the garrison to collect naval intelligence and might know something, so she planned to go out.

At this time, Fumiko Fumiko (Yamamoto Maika) visited.Because I was worried about having a deep understanding of the engagement, I went to find Xia Mei's.Natsumi told Fumiko, who had the same idea, saying that she was crushed by anxiety every day.Just as the two were crying, Shibahara Yuko (and Ai Miu Kukai) came.Yuzi told the two of them that they were mentally prepared as naval wives, comforting them gently, and encouraging them cheerfully. It doesn't matter.

After all, what will happen to Natsumi and Takimasaki, Fumiko and Fumimiji??
