Kämpfer: Season 1

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

Natsuru stops Akane from shooting Kaede and the attacker escapes when the bell for class rings. Natsuru realizes that the enemy also goes to his school and becomes wary of the danger and cautious of the other girls around him. He and Akane are interrogated by Shizuku Sangō, the student council president, about what happened in the library. Natsuru promises to let Kaede meet his Kämpfer form the next day, and Akane and their messengers suggest making Kaede hate Natsuru's Kämpfer form, but instead

Natsuru begins his first day in the girls side of the school where he is transferred into Akane's class and is very popular among the girls. Kaede confesses her love to Natsuru, but he is unable to answer due to his bracelet flashing. He gets interviewed by the newspaper club, who write a dubious article about him. Kaede refutes most of the rumors and things go well until Shizuku starts spreading a rumor that female Natsuru is dating the male one. Natsuru escapes to the library and transforms ba

As the cultural festival comes up, Natsuru is shocked to find that Shizuku has entered him into the Miss Seitetsu beauty contest. Natsuru gives Shizuku a shoulder massage in order to be replaced, but after Akane bursts firing her gun, the deal falls apart and Natsuru is still forced to compete. Deciding to go with a karaoke act, he (in Kämpfer form) and Akane go shopping for lingerie, though it gets out of hand when Shizuku decides to help out too. Kaede later joins them at the karaoke bar, wher

The cultural festival is about to begin and the class dress Natsuru and Akane in various costumes for the Miss Seitetsu beauty contest. In the changing room, Kaede interrupts the two of them and once again gets into an argument with Akane. Male Natsuru later meets up with Kaede, and gives her some encouragement, although she still considers him a rival. On the day of the beauty contest, Natsuru does not have an act, but then Kaede comes on performing a skit, throwing a bouquet into the audience.

Natsuru is surprised to find his childhood friend Mikoto has returned. When Kämpfer Natsuru heads to school, she is forced to participate in a 'quasi-maid café'. She is later accompanied by Shizuku, who warns her that a new Kämpfer will be coming. Kaede later joins them, and Shizuku subtly probes her to see if she has any knowledge concerning the Kämpfer and the Entrails Animals that spawn them. Kaede asks Natsuru for a kiss, but she declines and settles for a date around the festival instead. A

Natsuru, unexpectedly accompanied by Akane and Shizuku, arrives at Kaede's house, which has a lot of Entrails Animals. Kaede starts things off with a game involving two people biting through the ends of a Pocky stick. Akane's attempts at avoiding Kaede and Natsuru being paired together gets her stuck with Shizuku. In the second round, Akane pairs with Natsuru, but he breaks the stick before she can reach. After failing to get paired with Natsuru, Kaede ends the game and shows everyone her collec

Shizuku asks Male Natsuru to go out on a date with her. While Shizuku is generally insistent that it's a proper date, Natsuru just goes along with it thinking it is a plan to draw out the White Kämpfer. 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

Akane is having a romantic summer date with male Natsuru at the pool. However, Mikoto, Shizuku and Kaede show up as well. At the pool, Shizuku sees 3 White Kämpfers when they walked past Kaede. Shizuku sends female Natsuru to walk alone somewhere and is attacked and surrounded by a group of White Kämpfer, who introduce themselves as Sayaka Nakao, Ryōka Yamakawa and Hitomi Minagawa. Akane and Shizuku rescue Natsuru and to his dismay, Shizuku essentially says Natsuru was used as bait to get the Wh

Natsuru finds himself sitting next to Kaede outside the hotel, who hypnotizes him into making Shizuku his. Kaede then disappears when Natsuru, who can't remember anything after leaving the room, is found and confronted by Akane, Shizuku and Mikoto in their respective Kämpfer forms. They return to the hotel where they are greeted by Kaede who doesn't appear to recall seeing the fireworks with Natsuru either. Afterwards, they all go (with Natsuru in female form) to the women's baths, where Natsuru

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

Natsuru wakes up on Christmas Eve morning to find out that he and his messenger, Disemboweled Tiger, have swapped bodies! Disemboweled Tiger decides to head on outside to enjoy this occasion and sees Natsuru's friends Mikoto, Shizuku, and Akane on the streets only to notice that they've also been body swapped with their respective messengers, namely Strangled Stray Dog, Electrocuted Wildcat and Black Seppuku Rabbit, as well. The messengers have fun with their new bodies until they are caught sne
