"Her Declaration of War ～The Fighting Maidens～"

is the fourth episode of the Kämpfer anime.

Thanks to Akane, Natsuru’s female self is forced to enter in the beauty contest held during the next festival. He confronts her about it. For her not being in the contest, she agreed to massage her shoulders. When Akane barges in and attacks Shizuku and Natsuru, it proved her own mistake that the repairs to the wall were paid by the massage and left Natsuru still participating in the Contest. With the help of Akane, Natsuru goes shopping in order to prepare for the contest. First they help buy Natsuru bras. Unfortunately for both, Shizuku end showing up. She and Akane continue to help with the bras. Later, they head to a karaoke bar which Shizuku invites Kaede along. In the bar, Shizuku, Kaede, and Akane do turns in karaoke. Later, eventually the three decide to enter the contest with Nastsuru.
