Natsuru was an Ordinary High-School Student until the night he was chosen to be a Kämpfer and received the mysterious blue bracelet that can change him into his Kämpfer form. The blue bracelet means he's been chosen to be a blue side kämpfer by the Moderator.The bracelet changes him into a striking high school girl (complete with gender appropriate school uniform) who fights with magic and mostly uses fire attacks.Since his Kämpfer form is a pretty teenaged girl who's tall and has big breasts Natsuro attracts a great deal of mostly unwanted attention from both the male and the female students of his High School.
Accidental Pervert: Natsuru cops a feel while struggling to get Akane under control, does not get called out for it.
Action Girl/Faux Action Girl: Constantly zigzags between either trope — depending on his/her mood, (s)he can either be efficient or impotent in battle — though in the anime (s)he leans more towards the latter trope.
Brainless Beauty: A rare protagonist example. It gets more exaggerated with each adaptation; by the anime, you begin to wonder how Natsuru remembers to breathe.
Chaste Hero/Idiot Hero: He manages to simultaneously play both tropes, what with his obliviousness to the way the girls are throwing themselves at him (male and female side alike) and all. Then again, with Kaede practically controlling many aspects of his life...
Crossdresser: Happens only once in the midst of all this genderbending, right when his identity is compromised in front of Mikoto near the end of episode 6. It also happens in the manga, but since he was wearing pants at the time there, it's a bit less obvious.
Crossdressing Voice: Even when he gets married to his own self, has a kid all by his own self, and yet is still voiced by the same seiyuu.
Crouching Moron, Hidden Badass: Both the original novels and its adaptations agree that Natsuru is pretty wish-washy. But in the novels and manga, at least Natsuru can kick a lot of ass should (s)he get his/her act together.
A Day In The Lime Light: His male form in Episode 8, the only one (so far) that features him as his original self instead of his Kämpfer self.
Dogged Nice Guy: He's been in an one-sided love for Kaede since middle school.
Don't You Dare Pity Me!: Said quite unconvincingly after Sakura tells Female Natsuru how uninteresting his male self is to her.
Even the Girls Want Her: Female Natsuru is so pleasant to the eyes, even girls can't help but try to jump on her. Not even tomboyish Akane can resist.
Gender Vocabulary Slip: As a girl, Natsuru has to correct herself mid-sentence on several occasions, as she routinely forgets that girls are meant to use the gender-neutral/feminine pronoun ''watashi" when referring to themselves, not the masculine form "ore."
How Do I Shot Web?: At first, Natsuru doesn't know how to control his zauber magic or transformations. Later in the light novels and manga, Natsuru does gain the ability to change at will. In fact, he learned to do that faster than Akane.
Huge Schoolgirl: Despite changing into a girl, Natsuru keeps much of his/her original height.
Just Friends: Considers most girls who attach themselves to him/her not named "Kaede" as this, particularly Akane and Shizuru.
Kawaiiko: Chaste when it comes to love, so endearingly innocent she gets embarrassed looking at her own naked form in the shower, and that Squee of hers... absolutely adorable.
Love Makes You Dumb: He decides to just try to talk it out with Kaede, only to end up getting Brainwashed and Crazy. To further clarify, he just regained the memories from when she tried to brainwash him and went there because he felt there was still some doubt about her intentions.
Loves My Alter Ego: To the point that he's competing with his female form for Kaede's affections.
Man, I Feel Like a Woman : Averted — (s)he's so pure (s)he gets frightened to death with embarrassment just looking at his/her naked female self, much less try to find out what they feel like or even go to the restroom with them.
Satellite Love Interest: Natsuru has no motivation or goal of any sort beyond dating Kaede and he can't even explain why he likes the girl. Then again, recent developments could suggest that this behavior is a result of Kaede secretly influencing Natsuru.
Single-Target Sexuality: The driving force behind his utter stupidity. Almost certainly justified by Kaede's mind control.
Unwanted Harem: Let's see, one Meganekko with an Ax-Crazy alternate personality, one tease, one Genki Girl, and one Psycho Lesbian. Plus how many men and women out there that are too insignificant to mention. And still he insists that he's not popular with women...
To be fair, his female side is mind-blowingly popular with the ladies, whereas his male side only has one person that we know of attracted to it. Considering he doesn't like his female side much and would much rather be male 100% of the time, he's sort of justified when he says he's not popular with women.
Class: 2-4 Weapon Type: Gewehr (Colt M1911) Messenger: Disemboweled Black Rabbit Voiced by:Yui Horie (Akane), Yukari Tamura (Disemboweled Black Rabbit)
Akane is a high school girl who goes to the same school as Natsuru. She is a member of the school library committee and is a shy girl who wears glasses and has trouble talking to boys. However, she has a nice figure and she acts very cute. She likes anime and books related to it.She meets Natsuru when he was walking to school while threatening to shoot him. Since she is a blue type Kämpfer, she's Natsuru's ally. She's very anxious about Natsuru's love towards Kaede, but she's afraid of taking action.When changing into her Kämpfer form she undergoes a personality change. Her Kämpfer personality is much more militant and prone to acts of violence. Akane's hair and her eyes take on a red color.
Ax-Crazy/Blood Knight: As a Kämpfer, the normally sweet Akane becomes her complete opposite personality-wise — borderline psychotic, foul-mouthed, and always itching for a good fight, even with fellow Blue Kämpfer Natsuru.
Beware the Nice Ones: See that shy bespectacled girl from the library? She's also that nigh-psychotic gunslinger who gives no crap about collateral damage.
Clingy Jealous Girl: She hates it whenever Natsuru transforms into a girl, let alone having to contend with Kaede, with whom Natsuru is eternally smitten, and Shizuru, who's more straightforward than she ever will.
Covert Pervert: She always tends to jump to surprisingly perverted conclusions at Natsuru's comments. This is especially obvious when the guy is just innocently inviting her to his house, and she keeps getting all worked up.
[[quoteright:250: Gender: Female Year: 3rd Class: 4 Weapon Type: Schwert (chained daggers) Messenger: Electrocuted Wildcat Voice Actor: Kaori NazukaShizuku is the student body chairman of the Seitetsu Academy. This entitles her to go to the boys' side of the school as she pleases. She is an honor roll student and enjoys the popular support of the students and the teachers. As one of "Seitetsu Academy's beauties", Shizuku charms the male students of school.When she changes into her Kämpfer form, the inside of her hair normally black turns white. Her weapons are two daggers connected by a chain. Otherwise she doesn't change.
Defeat Means Friendship: Or at least convinces her that Natsuru is too much fun to kill. It's reveled later in the novels that Natsuru reminds her of a friend she lost due to the Kämpfer Wars.
Trickster Archetype: At least in the anime this actually works against her in her relationship with Natsuru. Natsuru being the Chaste/Idiot he is constantly interprets her attempts to get her/him to notice her into strategic planning be it against the White Kämpfers or just for the lulz after having been a victim of it for so long.
Natsuru's childhood friend, she's one year younger than him. Mikoto only recently reunited with him due to her father being an archaeologist who lives abroad. She's outgoing and innocent. She has the personality of an adventurer, always displaying physical abilities that no one can match. She doesn't have any problems with catching barehanded a snake or a spider, but, to see a man nude, is her biggest weakness and too hard for her to confront.She appears to have feelings for Natsuru and is more than a bit bothered by the presence of a girl with the same name as his (who in reality is Natsuru in his Kämpfer form). When she was attending the Miss Seitetsu contest of the school festival, she caught a bouquet that Kaede tossed and a Messenger was hidden in it. Due to that, she became a Schwert-type Red Kämpfer armed with a Japanese sword. Since she's a red Kämpfer, Natsuru does his best to stay way from her to avoid revealing the fact that male Natsuru and Blue Kämpfer Natsuru are one and the same. The question is: How long can he keep up the charade? (In the anime, his identity is compromised right away.)
Brainwashed / Brainwashed and Crazy: In the novels, Mikoto gets brainwashed by Kaede and attacks the purple betrayers (the red and blue Kämpfers that refuse to fight each other.). In the anime, Mikoto gets brainwashed to seduce male Natsuru and have sex with him, but she gets interrupted by Shizuku and Akane and attacks them afterwards.
Clingy Jealous Girl: She beats up Natsuru in episode 8 because she finds out that he went on a date with Shizuku. Although he tries to deny it was a date, Shizuku plainly tells him that it was a date repeatedly, and only he believed it was a mission.
Cry Cute: She looks so adorable when she's biting her "tasty" pillow at the end of episode 8.
A Gewehr-type Red Kämpfer. Midori is a part of the student council and Shizuku's partner. Midori doesn't like Natsuru for hogging all of Kaede's attention. She was ordered to watch over Shizuku, to keep her from finding out more about the moderators. Shizuku, in turn exploited Natsuru and Akane to have her sidelined because Kämpfers of the same color can't fight each other.
Demoted to Extra: The anime reduced her already small role into merely being mentioned by name during episode 3 and 4's next episode preview. In a fake narration.
A Schwert user. Her Schwert is a kusarigama.A younger sister of Makie Ueda of the Seitetsu Gakuin Class 5 of the first grade. Therefore, Rika isn't a student of the Seitetsu academy. Rika got her Messenger animal doll from her older sister accidentally who in turn got the doll from "Evil" Kaede. Her weapon is a sickle and chain.
The Danza (Her voice actress shares her surname with the character).
Schwert user. Her Schwert is a sabre.Seitetsu Class 1 of the second grade. Her weapon is a saber. She's a book committee member, but is only eager to do her job after she transforms. She seems as your today's gal-like girl, but she becomes considerably polite when she transforms. (She's type which personality completely changes like Akane.
Gewehr user. Her Gewehr is an Ingram MAC-10 machine pistol.Seitetsu Class 5 of the second grade. She has before transformation a typical young idol face who is suitable for her age, but her appearance is that of a grown-up after she transforms. Ryouka appears for the first time in the municipal library on the second floor.
A Zauber user. She can shoot light bullets.A Seitetsu third grader. She bolts of light thanks to magic (she's a zauber type) which can be used perfectly for both offense and defense. She's the ace of the track and field club. Her hair becomes green when she transforms. She battles against Natsuru in an Italian shop of her father. Currently she's the leader of the white side.
Shizuku's childhood friend and one of the Three Beauties of Seitetsu, she has many admirers, Natsuru being one of them. She loves the entrails animal series' Zumotsu Animal and has a large collection of stuffed Zumotsu Animal dolls and likes to present them to her friends; those who receive the dolls, however, tend to end up becoming Kämpfers. She began to develop a crush on Kämpfer Natsuru after being saved from Kämpfer Akane at the beginning of the series. Later, it turns out there's more to her than meets the eye.
Manipulative Bitch: The anime pretty much stated outright that she was the one who orchestrated the whole Kämpfer business, may or may not have brainwashed Natsuru into falling for her, and is more than glad to turn Natsuru and his harem against each other so she can see them killing each other off.
The haunted house. When she sees a mannequin hung with a rope on her neck, she says it's cute.
Sword and Gun: She wields a katana in one hand and a modified Beretta 92G Elite II pistol in the other.
Villainous Breakdown: Loses her composure when she realizes she almost made out with Natsuru after he transformed back into a boy at the very last second, prompting her and the White Kämpfer to fall back for the time being.
Nickname given to this classmate by Natsuru. Natsuru just assumes that she's the chairperson but it's really unclear if she's really the chairperson. She leads a trio of girls that makes makes female Natsuru's school life miserable. She generally comes with ways to exploit Natsuru to make money and amusement out of his female side.
Nickname given to this classmate by Natsuru. Natsuru just assumes that she's the assistant chairperson like the chairperson but it's really unclear if she's really the assistant chairperson. She's part of a trio of girls that annoy Natsuru. She's a little too attracted to Natsuru's female form.
The "Treasurer" dubbed by Natsuru, carries around a calculator and often tries to sell Natsuru something. Like the "Committee Chairperson" and "Assistant Committee Chairperson", it's really unclear whether she's serving as an accountant.
