Manga / Oh, My Sweet Alien!

Go To
Oh, My Sweet Alien! (Yome ga Kore na Mon de) is a Science Fiction Romantic Comedy manga by Koji Miyata, which was serialized sporadically in the seinen magazine Fellows! from 2009 to 2015. It is licensed in English by Yen Press, who published its two volumes in an omnibus.

The story is about an average Japanese Salaryman named Nobuo Makabe and his homemaker wife, who just so happens to be an extraterrestrial.

This manga contains examples of:

  • A-Cup Angst: The alien briefly suffers from this in Chapter Eight, when she finds a selection of porn magazines and DVDs starring women with large breasts.
  • Alien Abduction: Nobuo met his bride when her spaceship abducted him.
  • Bizarre Alien Reproduction: The alien reproduces by encasing herself in a caterpillar-like chrysalis, which she and the baby both burst out of when the child is ready to be born.
  • Broken Masquerade: The story ends with aliens all over the world revealing their true identities.
  • Clarke's Third Law: The Venusian human disguise necklaces seem to be magic, but Madoka describes hers as "the latest model", suggesting that they are in fact just very advanced technology.
  • Embarrassing Old Photo: When the alien's parents come down to Earth for a visit, they show off some old family photos, one of which - to her extreme consternation - is a cute picture of her as a baby.
  • Exposed Extraterrestrials: The alien does not wear clothes in her natural form, and nudity is a part of her culture. She knows enough to wear clothing in her human disguise, though.
  • Flying Saucer: The alien's parents fly a quintessential, '50s-B-Movie-style model.
  • Flock of Wolves: A full third of the people in Nobuo and the alien's apartment building are aliens.
  • Full-Body Disguise: When going out in public, the alien wears a skintight bodysuit that makes her look like a human. It's even anatomically correct, even though she always wears clothes.
  • Green-Skinned Space Babe: The alien looks just like an attractive human woman, aside from her huge eyes, scaly patches of skin, and tendrils for hair. Same goes for her mother.
  • Happily Married: Nobuo and the alien utterly adore each other. Same goes for the alien's parents, who get along fabulously after who-knows-how-many years together.
  • I Have Your Wife: At the end of Chapter Five, Asora is abducted by a blob-like alien. The entirety of Chapter Six involves Nobuo, his wife and the Venusian siblings trying to rescue her.
  • Innocent Fanservice Girl: Though the alien can remember that humans are expected to wear clothes when she's sober, getting her drunk can make her forget, and try to take her clothes (and even her human skin) off in the middle of an office party.
  • Interspecies Romance: Nobuo and the alien of course, but weirdly, the alien herself is also the product of one. Her mother looks similar to her, but her father is a blob-shaped Starfish Alien.
  • Losing a Shoe in the Struggle: Nobuo lost one of his shoes when he was abducted.
  • Love at First Sight: The moment Nobuo first laid eyes on his future wife, he found her so beautiful that he immediately asked her to marry him. Subverted- he only said that because he was delirious from the abduction experience, and wasn't thinking clearly. Luckily, they turned out to be a great match anyway!
  • Mistaken for Cheating: The Venusian siblings see Nobuo going into a sex hotel with another woman and assume that he's cheating on his wife. When they confront him, it turns out that the woman IS his wife - her usual skin is out for maintenance, and the manufacturers accidentally sent the wrong model skin as a replacement, but she still wanted to try it out. The reason that she and Nobuo went into the hotel is because the suit is too tight on her, so they ducked inside so that she could take it off for a bit.
  • Ms. Fanservice: Madoka isn't afraid to show off her body.
  • No Name Given: Whatever the alien's name is, it's never stated in the story. The endnotes refer to her as simply "the alien wife".
  • Not What It Looks Like: The very first story opens with Nobuo taking a bath and the alien cleaning all of her human skinsuits in the washing machine, when suddenly a neighbor comes to the door unexpectedly. The couple scrambles to take the alien's suit out of the washer, put it on her, get a shirt on her, and answer the door... and of course, when it opens, the neighbor seems them both soaking wet and nearly naked, gets the wrong idea, and awkwardly sees herself out.
  • Obnoxious In-Laws: Nobuo's mother acts like this towards the alien.
  • Ocular Gushers: The alien's eyes (as well as her dad's) shoot powerful lasers when they cry.
  • Oh, Crap!: The incident under A-Cup Angst is settled when Nobuo reveals he was just holding the magazine for a friend. He then promptly freaks out when the alien asks about the magazines she found focused on butts...
  • Paper-Thin Disguise: In stark contrast to her mother's perfectly convincing human suit, the couple's baby daughter Asora goes out in public with her bulbous glowing eyes still in full view, and her tentacle hair merely hidden under a hat.
  • Precocious Crush: Asora develops one on Ichimaru.
  • Prehensile Hair: The alien's hair is made of tendrils, and she uses them to do dozens of household chores at once.
  • Rite of Passage: In the alien's culture, the passage from childhood to adulthood is achieved when one probes an alien abductee. However, she was too afraid of hurting her subject (Nobuo) to go through with it.
  • Seduction-Proof Marriage: Madoka repeatedly fails to seduce Nobuo since he considers his wife the only woman for him.
  • Shapeshifting: The Venusian siblings Madoka and Ichimaru, a pair of aliens who, unlike Nobuo's wife, can change instantly between their true form and their human disguises via special necklaces.
  • Sleep-Mode Size: After being captured, the Delaro-sa alien is implanted with a chip which prevents it from growing any larger than its current size.
  • Telepathy: Seems to be the only way that the alien's father can communicate with Nobuo. The alien herself also speaks with him in this manner while she's in her cocoon.
  • Time Skip: The last third of the final chapter takes place eight years after The Masquerade is broken, and Earth has been made a member of the Galactic Alliance.
  • Translator Microbes: The alien's planet has developed a universal translation device that gets plenty of use when visitors come to the Makabes. The alien seems to have also learned to speak Japanese naturally, however, as she can still communicate perfectly fine with Nobuo even if the device malfunctions.
  • The Vamp: Madoka falls in love with Nobuo, gets a job at his office, and goes about trying to win him over in any way that she can, up to and including sexually propositioning him in the middle of the parking garage. Nobuo isn't tempted one bit.
  • Weakness Turns Her On: In one chapter, Ichimaru challenges Nobuo to a race hoping to get the alien to fall in love with him, since he believes Women Prefer Strong Men. While he does win, the alien still ignores him in favor of her (slightly) injured husband.
    Ichimaru: I see... sympathy for an injured comrade... so this is the love of the earthlings!
  • What You Are in the Dark: While Madoka and Nobuo are alone in a parking garage, the former asks for a ride home before stripping, with the obvious implication that she'll have sex with him in his car. He refuses near instantly because the only woman for him is his wife.
  • Women Prefer Strong Men: Ichimaru believes this, so he challenges Nobuo to a race since he thinks winning will get the alien to fall in love with him. Subverted since the alien would rather tend to her injured husband.
