"Destiny ～The Chosen Ones～"

is the first Kämpfer episode of the anime. It originally aired on TBS at October 2, 2008.

The episode starts off with a blue-haired girl running from a red-haired girl chasing her and firing with a loaded pistol. Later, the same blue-haired girl wakes up in bed shocked to discover her own body, and even weirder sees a tiger doll thing that looks as if it's entails are sticking out of its gut. The doll's name is Harakiri Tora, and it tells the girl, Natsuru Senō, that she was chosen to become a Kämpfer. After freaking out for a bit, Natsuru wants to go back to sleep, and the doll helps by kicking her in the face knocking her out. When Natsuru wakes up, he's a boy again.

On his way to school, Natsuru tries to catch the bus with his crush, Kaede Sakura, but on the way to school he runs into the same red-haired girl with the pistol from his nightmare. Seeing his bracelet glowing, he disappears from the scene and turns back into a girl with a brief magical girl transformation sequence. After a brief fight, Natsuru finds out s/he can throw fireballs at people, and saves the red-haired girl from a falling lamppost. The red-haired girl decides to leave. Eventually, arriving at school as a guy, Natsuru runs into a girl who introduces herself as Akane Mishima. Akane reveals that she is that red-haired girl that attacked him earlier, except this time she's a shy, bespectacled librarian who seems to apologetically find lewd double-entendres in everything she says. She explains that Kämpfer carry one of three weapons: Schwert (sword), Gewehr (gun) or Zauber (magic), kind of like rock-paper-scissors, except no weapon type appears to have a natural advantage over another.

The next day, Natsuru runs into Kaede again, thinking that she finally wants to confess her love to him. Instead, she asks Natsuru to introduce her to the female version of himself, without knowing that they are actually the same person. He decides to ask Akane for advice, but as the two of them are talking in the school's library they find themselves under attack by another Kämpfer with a chain-blade weapon that cuts through the bookshelves like paper. After one attack, Kaede is shown standing in the rubble. Thinking she's the attacker, the transformed Akane points her gun in Kaede's direction and fires as the episode ends.


 * Natsuru Senō
 * Kaede Sakura
 * Akane Mishima

 * "You may be a Kampfer, but you're not a Mobile Suit!" This line from the first episode is a reference to a certain Zeon mobile suit (MS-18E Kampfer) from Gundam 0080: War in the Pocket.


 * "The red ones are really three times faster!" This line from the second episode is another Gundam reference, both a reference to the original series (Gundam 0079) and a meme that applies to the entire franchise as a whole. This line in MSG referred to how Char Aznable's personal Zaku-II was three times faster than a regular Zaku-II, and Char prefers his mobile suits in red, thus the "Red = 3 times faster" meme. In Kampfer, Akane says this line in reference to Shizuku's red bracelet, with the irony being that Kampfer-form Akane has blood-red hair.


 * During episode 1, Natsuru and Akane are talking about Seppuku Kuro Usagi in the library. There's a drawing image including Yukari Tamura & Michiko Nomura in the magazine. Yukari Tamura plays the role of Seppuku Kuro Usagi while Michiko Nomura plays the role of Harakiri Tora.


 * ​ In one of the pages in the same magazine that had information on Yukari Tamura and Michiko Nomura, there is a miscolored shot of the Turn A Gundam's face.
