Manga: DNAČ

DNA2: In the future, the world's overpopulation problem is traced back to Junta Momonari and his supernatural ability to seduce women, which gains him the title of "Mega Playboy". Though you'd never know it, since currently Junta's powers have not woken up, and he's just your typical Unlucky Everydude with a literal allergy to women... that causes him to throw up whenever he sees a naked girl that isn't his mother. Which happens in front of Tomoko Saeki, the most beautiful girl at his school.

Right after this hilariously horrible incident, an Action Girl named Karin Aoi travels back in time to "assassinate" his ability by shooting him (non-lethally) with a special bullet that alters his DNA before his powers as Mega Playboy come to the surface... Unfortunately, she accidentally used a bullet she personally customized to create a "perfect husband" - causing Junta's powers to not only awaken, but be exponentially stronger.

Now Karin has to find him another way to control Junta's powers, or face the death penalty. While waiting for new orders from her superiors, she stays at Junta's home to keep a watch on him and learn about his environment (and the girls who could be affected, like Tomoko), and then she meets Ami Kurimoto, Junta's Unlucky Childhood Friend who is the only girl who is immune to the Mega Playboy's charm. Now she has to see what to do before Junta breaks havoc among the female populace!

Originally a short-lived early 1990s manga by Masakazu Katsura (the same author as Video Girl Ai), later adapted into a Twelve-Episode Anime. Its plot and characters also formed the basis of a famous Newgrounds Dating Sim called SimGirls.

DNA2 provides examples of the following tropes:

  • Action Girl: Karin; Rurara
  • Anime Hair: Junta, to the ridiculous level of spiky hair.
  • "Blind Idiot" Translation: A very odd and annoying one happens in the Mexican Spanish translation of the manga, and also overlaps with Viewers Are Morons, since unlike other examples, this is enforced by the publishers: Basically, any character with name who use the letter "J" (Junta, Ryuji, etc) is written with "Y" (Yunta, Ryuyi, etc) since the publishers thought the Mexican readers could not be able to pronounce those names right.note  The European Spanish translation, who was translated a few years previously before the Mexican one, avoids this.
  • Bitch in Sheep's Clothing: Tomoko initially comes off as this, but she's actually incredibly lonely to the point of being a Woobie.
  • Easily Forgiven: Tomoko, to her Jerkass boyfriend Ryuuji.
  • Disappeared Dad: Junta's father died when he was young, so he was raised only by his Apron Matron mother Chiyo. Tomoko's dad works outside of Japan.
  • Fartillery: Kotomi's... biggest problem, shall we say. She farts when she gets nervous, and since she's a gym practitioner... It should be noted that her farts in the manga seem to venture more toward Fartillery territory than the anime; in the anime, her farts are average sounding but in the manga they're often drawn like explosions to emphasize their volume.
  • Gass Hole: As mentioned above, poor Kotomi's disorder turns her into this when she gets nervous (which happens quite frequently) making her one of the rare female gassholes in fiction.
  • Jerkass: Ryuuji. Even more after he gets shot by Karin by mistake, too, and gains powers from that.
  • Important Haircut: Kotomi has Girlish Pigtails, which she later trades for a cute pageboy style.
  • Karma Houdini: Okay, so Ryuuji ends up in the hospital and then gets Brainwashed and Crazy... but what about the several cases of attempted murder along with attempted rape?!
  • Lonely Rich Kid: Tomoko's Freudian Excuse. Not only her dad is a very rich businessman who spends more time abroads than with his only daughter, but her mom is dead.
  • No Badass to His Valet: Why Ami is the only known female actually immune to Junta's Mega Playboy persona.
  • The Ojou: Tomoko
  • Operation Jealousy: Tomoko once asked Junta to go out with her to make Ryuuji jealous after a big fight. And it's right after the horrible (and hilarious) consequences that Karin comes in...
  • Plot Hole: Rurara's existence is both this and a time paradox. First, Karin tells Junta that Mega Playboy only fathered sons and the trend continued down the line of only sons. Then, after the Mega Playboy gene is removed from Junta, Rurara doesn't disappear. The only logical explanation for this is that she was either his descendant through Ami or that being descended from Mega Playboy was a bluff.
  • The Pornomancer: Junta is supposed to grow into this.
  • Sexy Shirt Switch: Subverted. When Junta wakes up at morning, he finds Karin sleeping on a futon wearing one of his shirts and her panties... but since Junta is literally allergic to girls, there is NO way something could've happened. Karin was wearing his shirt just because Junta's mother Chiyo put it on her when she was passed out.
  • Ship Tease / Will They or Won't They?: Junta falls for Karin pretty early on, and her wacky inner monologue reveals that she likes him even when he's not radiating distilled sexuality.
  • Shout-Out: Mega Playboy mode Junta is very obviously based on the hair Gohan sported in Dragon Ball Z once he hit Super Saiyan level 2. Justified, as Masakazu Katsura is a personal friend of Akira Toriyama and both authors loves to throw jabs at each other on their respective works.
  • Tsundere: Both Karin (Type B) and Ami (Type A).
  • Vomit Discretion Shot: Even in the opening credits!
