[[caption-width-right:318:Mayuko & Niea]]
The aliens have landed! But that was many years ago, and no one really cares any more. All the fuss and excitement over the arriving [=UFOs=] has, for the most part, settled down, and people have returned to everyday life. Aliens, too, are gradually integrating into normal human society. Our story follows one Mayuko Chigasaki, a hard-working, self supporting cram-school student, who also works multiple part-time jobs simply to pay for school and feed herself. Niea is the lazy, selfish, freeloading alien who lives in her cupboard, eats all her food, and generally drives her nuts.

''Niea_7'' is an {{anime}} series created by {{Creator/Yoshitoshi ABe}}[[note]]intentional capitalization[[/note]], produced with the same team that worked on ''SerialExperimentsLain''. Despite being a typical Yoshitoshi [=ABe=] product it is ostensibly a comedy series It holds much more interest as a SliceOfLife series following everyday life in the sleepy district of Enohana, and tracking Mayuko's struggles to come to terms with herself and the world around her.

!!''Niea_7'' provides examples of:

* AliensSpeakingEnglish: Japanese, actually, but you get the idea.
* AnimeChineseGirl: Karna dresses and behaves like a stereotypical Chinese girl, even though she is actually an alien.
* BalloonBelly: Niea and Karna in episode 8.
* {{Bare Your Midriff}}/{{Stripperiffic}} Niea's torso is covered by what amounts to a vest with a single button in the middle keeping it closed.
* BerserkButton: Don't make fun of Karna's antenna. Just... don't.
* BigEater: Niea. About the only thing she does is eat, sleep and build [=UFOs=].
* BlushSticker: Niea sports two perpetual ones. Karna too, so it's likely an alien thing.
* CatGirl: Niea is not really one, but she gives off the vibe with her ears, [[CuteLittleFangs fangs]] and mannerisms.
* ClosetSublet: Niea.
* {{Cloudcuckoolander}}: Chiaki manages to even outdo the titular character at times.
** Karna also tends to have a tenuous hold on reality.
* ComingOfAgeStory: Definitely for Mayuko -- but also for Niea, to some extent.
* CranialEruption: Niea receives quite an amount of abuse from Mayuko. Deservedly.
* CuteLittleFangs: Niea.
* DoesNotLikeShoes: Niea happens to be barefoot a lot.
* EverythingsBetterWithPandas: Karna loves panda prints, in line with her "{{Chinese girl}}" shtick.
* FantasticCasteSystem: The aliens seem to have one.
* FantasticRacism: A common theme throughout the series, also dealing with the sudden immigration of the aliens.
* {{Fauxreigner}}: Chada, the Indian-stereotype convenience store owner who is actually an alien.
** Also Kana, who is anything ''but'' a {{Chinese girl}}.
* FuroScene: Quite a few. Not surprising, considering Mayuko lives above a public bath.
* GenkiGirl: Niea, albeit more of the agressive type.
* HandyFeet: Neia has a habit of opening doors with her feet.
* HomemadeInventions: Niea's makeshift [=UFOs=].
* HumanAliens: Human plus antenna and pointy ears. Never really addressed
* {{Jerkass}}: Niea has to be the worst possible person to live with.
** JerkassFacade: It is hinted that [[spoiler:Niea's attitude is a way of coping with the rejection by her own people]].
* LargeHam: Karna.
* LonersAreFreaks: Niea never socializes much with anyone, human or alien. [[FantasticRacism She has her reasons, though]].

* {{Otaku}}: Chiaki, of [=UFO=]s.
* PerpetualPoverty: Mayuko suffers from this, which isn't helped by Niea's freeloading.
* PowerLevels: The aliens rank themselves as "Plusses" and "Unders". Niea is a rare, ultra-low ''Under 7'', since she even lacks an antenna.
* PrettyFreeloaders: Niea (although whether she's pretty is up for debate).
* PsychicPowers: The aliens seem to possess them, or at least the ones having antennae -- which Niea suspiciously ''lacks''.

* TomboyAndGirlyGirl: Niea and Mayuko. Sort of.
* UnusualEars: Niea and the other aliens.
