"His Midsummer ～Tropical Cyclone of Romance～"

is the ninth episode of the Kämpfer anime.

Akane and Natsuru go to a hotel that they rented. Unfortunately both Shizuku and Mikoto make a surprise appearance and revealed that they rented a double room also next door to Natsuru & Akane's. Mikoto and Shizuku making a surprise appearance]]The infighting over Natsuru sent Natsuru non-responsive. Of course Mikoto and Shizuku gave Natsuru a boost by taking Kaede along much to Akane's displeasure. Later at the pool, when everybody is in swimsuits, Natsuru only googled-eyed Kaede in hers much to the surprise of the others and oblivious of Kaede herself. She simply asked about the female Natsuru. Shizuku said she would be along later. Then Kaede asked Shizuku to teach her how to swim, given her grudge and rivalry with Natsuru. After some play in the water and coming out, Natsuru gets bombarded by the three girls with Kaede looking on. Then Shizuku gave a hint to Natsuru to transform to satisfy Kaede. Of course, he gets embarrassed by his girl swimsuit. Ironically she asks Natsuru to teach her despite his male self, even when she says that she dislikes the flaws that he has which crushes his heart. Later, Natsuru is sent on an errand but ends up in trap set by three White Kampfers. Both Akane and Shizuku show up and gain up on them and they retreat and disappear. Later at the room, Natsuru informed Akane that he said to Kaede that the female Natsuru left but under her gaze had added she would return later. This upset Akane. Of course the four Entrails Animals came out of the bathroom, seemingly from bathing. They asked Natsuru to dry them and he did roughly and then hanged them up like clothes. Soon the others call to meet them in the next room. There, things gets problematic with Natsuru when Shizuku reveals her affection toward him. It does even further when she kissed him boldly. Then Kaede took Natsuru out.
