"Invite ～The Uninvited Guests～"

is the seventh episode of the Kämpfer anime.

Natsuru is glad that he is finally invited to Kaede's house. Unfortunately, the invite is for his Kampfer form. Of course when he had just exiting his house, he is confronted by Shizuku and Akane who learned of the invite from Kaede. Akane rebukes him for not telling her. Of course they tell him that they are joining him to Kaede's house. Kaede opens the door and sees that Natsuru and company had arrived. They see that she had the house decorated with Entrails Animals. Kaede then at the living space decided to have a stick kissing game set up. Of course Akane knowing Kaede and her own love for Natsuru, kept Kaede from having her having it with Natsuru and herself.

Later Kaede shows them her Entrails Room. There is a lot of the stuffed animals in the room. Shizuku asks her which she loves the most and picks out Hiaburi Raion. Mikoto drops in and makes a pot of curry. Of course Shizuku dumps curry on Natsuru which angered Mikoto and took it out on Natsuru. Shizuku suggests that Natsuru get cleaned up in a shower. Of course, in the bathroom, Kaede tells her what she needs to do so. Unfortunately whenever Natsuru tried to transform back to normal, Kaede keeps popping in and stopping in. In the end he showers in his Kampfer form. Of course Kaede enters yet again, and leads to an argument with Akane who follows suit. Of course Mikoto impulsively heads to join Natsuru much to the dismay of both Akane and Kaede who tries to stop her.

Later they are in Entrails Animal pajamas. After an argument of who sleeps with Natsuru, in the end she sleeps alone. Of course he returns to normal form by accident. Then Kaede sneaks into bed with him. Getting closer and trying to take advantage of Natsuru, until Akane interrupts in her Kampfer form. Of course Kaede is unconscious. The scuffle is interrupted by a unknown Kampfer which is revealed to have a white bracelet, not red nor blue. She only retreated after having her attacks blocked by Shizuku. Afterward Shizuku questions Natsuru about Kaede in his bed. After he leaves, she wonders if she is jealous and in love with Natsuru.
