S1 E1 • Schicksal: The Chosen Ones

Natsuru Senō wakes up to discover one morning that he has transformed into a woman, upon which a stuffed animal tiger, Disemboweled Tiger, who introduces itself as a messenger, tells him that he has become a Kämpfer, which must do battle with other Kämpfer; since Kämpfer must be female, Natsuru transforms into a female version of himself. The next morning he is attacked by another Kämpfer named Akane Mishima wielding a sidearm. Natsuru protects his friend Kaede Sakura from Akane's attack, before saving Akane from a falling lamppost. Natsuru is approached the following day by a shy girl who reveals herself to be Akane, who is completely different in appearance and personality when in Kämpfer form. Akane tells Natsuru as much as she knows about the Kämpfer, even helping him when he transforms. Apparently, they are allies due to their bracelets being the same color, blue, hence they become known as Blue Kämpfer and that their enemies are the Red Kämpfer, who have red bracelets, accordingly. At the end of the day, Kaede tells Natsuru that she has fallen for his Kämpfer form. The next day, when he goes to Akane for advice, they are attacked by another hidden Kämpfer while in the school library. When Kaede suddenly appears in the wreckage, Akane assumes she is the enemy and shoots her gun at her. Source: TBS (translated)

Shizuku asks Male Natsuru to go out on a date with her.

After visiting an aquarium and having a picnic, Shizuku questions Natsuru about why he likes Kaede. Hesitating to ask if he suspects a connection between Kaede and the Moderators, she then talks about the Kämpfer battle, remembering a lost ally. Natsuru has a quick nap with a curious dream, only to wake up on Shizuku's lap, curious as to whether she tried anything while he was asleep. At the end of the date, Mikoto spots them, and is not too happy about Natsuru going a date with Shizuku, not helped by Shizuku's honest comments.

Akane and Shizuku rescue Natsuru and to his dismay, Shizuku essentially says Natsuru was used as bait to get the White Kämpfer to reveal themselves, who end up running away rather than fight them on equal terms. Later male Natsuru and the girls are having a fun time in the hotel. Akane and Mikoto are in shock that Natsuru went on a date with Shizuku, and Shizuku even goes so far as to kiss Natsuru in front of the others.

Afterwards, they all go (with Natsuru in female form) to the women's baths, where Natsuru's hypnotism kicks in and he then brings Shizuku back to the room to make a move on her, but he gets knocked out when he let slip that Kaede told him to do it.

S1 E11 • Election: The Song of Joy

Shizuku invites Natsuru over to her house to tell her about Kaede, getting Kaede's Burnt To Death Lion to spill the beans about the Kämpfer system. She recalls that her close friend Tamiko was killed in a Kämpfer battle and has since sworn vengeance against whoever responsible for the establishment of Kämpfer combat. When Natsuru confronts Kaede about this, he once again falls under Kaede's hypnotism. With Natsuru under her control, Kaede and the White Kämpfer trap and capture Shizuku, Akane and Mikoto. When the three of them wake up later chained together, Kaede tries to get Natsuru to finish them herself, but he spots a keychain he previously bought for Shizuku and snaps out of it, declaring that he will not betray his friends despite his love for Kaede. This declaration encourages Shizuku, Akane, and Mikoto to fight with renewed resolve, enabling them to break free and allowing them to easily defeat the White Kämpfer. Kaede tries enticing Natsuru once again, but he transforms back into normal form, putting himself out of the fight (and out of Kaede's disposal) as well as forcing Kaede and the White Kämpfer into retreat. With the battle over, Shizuku, Akane and Mikoto turn their attention to Natsuru, initially jumping him for trying to make out with Kaede in front of them before competing against each other to see who can appeal to Natsuru best with their "qualities" (to the point of kissing him, grabbing his hands and forcing him to touch sensitive areas, and rubbing their breasts onto him).

The messengers have fun with their new bodies until they are caught sneaking out on a food bill and are forced to perform in a show.
