* WhatYouAreInTheDark: 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 almost instantly because [[SeductionProofMarriage the only woman for him is his wife]].

* TheVamp: 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.

* TimeSkip: The last third of the final chapter takes place eight years after TheMasquarade is broken, and Earth has been made a member of the Galactic Alliance.

* ACupAngst: The alien briefly suffers from this in Chapter Eight, when she finds a selection of porn magazines and DVDs starring women with large breasts.

* PaperThinDisguise: In stark contrast to his mother's perfectly convincing human suit, the couple's baby son Asora goes out in public with his bulbous glowing eyes still in full view, and his tentacle hair merely hidden under a hat.

** ClarkesThirdLaw: Their necklaces seem to be magic, but Madoka describes hers as "the latest model", suggesting that they are in fact just very advanced technology.

* ExposedExtraterrestrials: 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

* InterspeciesRomance: Nobuo and the alien of course, but weirdly, the same goes for the alien herself. Her mother looks similar to her, but her father is a blob-shaped [[StarfishAliens Starfish Alien]].

* RiteOfPassage: It seems that, in the alien's culture, the passage from childhood to adulthood is achieved when one probes an alien abductee. She herself was too afraid to go through with it.

* TheVamp: Madoka (secretly an alien invader from Venus) 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.

* {{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.

* GreenSkinnedSpaceBabe: The alien looks just like a pretty human woman, aside from her huge eyes, scaly patches of skin, and tendrils for hair. Same goes for her mother.
* InterspeciesRomance: Nobuo and the alien of course, but weirdly, same goes for the alien herself. Her mother looks similar to her, but her father is a blob-shaped [[StarfishAliens Starfish Alien]].

* NotWhatItLooksLike: The very first story opens with Nobuo taking a bath and the alien doing chores while washing 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, and awkwardly sees herself out.

* PrehensileHair: The alien's hair is made of tendrils, and she uses them to do dozens of household chores at once.

A ScienceFiction RomanticComedy manga by Koji Miyata, about an average Japanese {{Salaryman}} named Nobuo and his homemaker wife, who just so happens to be an extraterrestrial.
