Shout Out / Haiyore! Nyarko-san

This anime is like a geek test. Indeed, a blog was specifically set up to catalogue most of the references found per episode. Some of the more obvious Shout Outs in the series can be seen below. It even makes sense in-canon, since the premise revolves around Aliens Steal Cable.


  • In several episodes, portraits of H.P. Lovecraft and August Derleth can be seen on the living room walls.
  • In Episode 1 of Nyaruani, Nyarko channels Setsuna F. Seiei as she declares "I am...we are...Cthulhu!"
  • Episode 9 of the first Nyaruani has Nyarko say that in space kindergarten, she went around looking for kids playing make-believe and beat them up, with the Catch-Phrase "I'll shatter that pretend game of yours!" This earned her the nickname "Slacker Breaker"note . In case you missed the reference, they just go ahead and throw up a title card that reads "A Certain Slacker-Breaking Nyarko", with a silhouette of Touma behind it.
    • Cuuko's story about why she fell for Nyarko involves her being forced to play the bad guy in a pretend Saint Seiya game; one of the other games Nyarko mentions busting up is "Federation vs. Principality", with censored-out Bright Noah and Garma Zabi (and Nyarko in Sayla Mass's uniform).
  • Episode 11 of Remember My Love(craft-sensei) has Nyarko assure Mahiro that everything would be alright as they would erase everyone's memories once they were done. Then she takes out the neuralyzer. Mahiro responds that something about that object seems familiar and gets a mental image of Tommy Lee Jones as Agent K.
    • On top of that, Mahiro's mental image of K is saying "There's coffee", referring to Jones appearing in a series of ads for UCC Coffee in Japan (in which, ironically, he plays an alien who's trying to understand human culture).
  • In episode 12 of Remember My Love(craft-sensei), Nyarko's description of Space Comiket includes an image of the Gaijin 4koma Reaction Guys.
  • In one episode, Cuuko quotes the line "swans look calm but are actually kicking furiously under the water" while a Fender bass guitar floats on the background, a reference to K-On!'s first season ED song lyrics.

Haiyore! Nyarko-san (Season 1):

Haiyore! Nyarko-san W (Season 2):

Haiyore! Nyarko-san F (OVA)

  • The F in the season's title is short for Final Countdown, doubling as a reference to Kamen Rider Den-O and alluding to the fact that it will conclude the story.
  • The official name of the OVA is "Crawling Switch On, Chaos is Here!", a reference to Kamen Rider Fourze, specifically to Astroswitch activation phrase and Gentaro's post-transformation Catch-Phrase.
  • The weapons what Nyarko and Mahiro are given to defend themselves against a group of monsters are Kamen Rider Gaim's Daidaimaru and Musou Saber.
  • During the intro, one of the posters seen in the store is the cover for Is It Wrong to Try to Pick Up Girls in a Dungeon? Volume 1.
  • When being told her mission after being kidnapped, Nyarko does the Gununu face.
  • The second part of Nyaruko's "recap" was her, Cuuko, and Hasta saying they'll sing to stop a war.
  • There are multiple spider-themed references in regards to the attraction the crew visit like having the logo of The Amazing Spider-Man 2 on the tickets and having Spider as the guide and Muramasa (who can turn into a mechanical spider) as a maid on the attraction. This is to serve as clever foreshadowing for the fact that Ato-ko is behind the whole thing.

Light Novels:

  • The covers of every light novel (sans the first) shows Nyarko doing a different Rider's transformation pose; these poses are used again in the opening sequence of Nyarko-san W. This gets taken a step further with Volume 8, which had two covers, the standard release where Nyarko imitates Kamen Rider BLACK and the limited edition where she imitates Kamen Rider BLACK RX. Combine the two, and you get a nod to Kamen Rider Decade which had Black and RX transform side-by-side for the first time.
  • The fact that Mahiro is apparently a Ripple-Effect-Proof Existence may make him a Singularity Point.
  • In the seventh novel/episode 8 of season 2, Shantak-kun turns into a little girl with help from Cuuko. Nyarko's reaction is to claim that There's no way my pet can be this young a girl.
  • The main antagonist of Light Novel volume 8 is Agent Smith, his full name is Clark Ashton Smith and he's working for cracker group call Digital Beings. He also appears in Episode 9 of the Second Season.
  • Later novels mention two alien websites, UchuuTube and its rival Mi-Go Mi-Go Douga.
  • An illustration from the novels depicts various forms of Nyarlathotep from Japanese media. (Persona, Demonbane, etc.)


  • The official Nyarko-san event scheduled for August 2014 is called "Farewell Nyarko-San: The Final Countdown", a play on the subtitle for the third Kamen Rider Den-O movie.
    • The OVA that was announced at said event is named Haiyore! Nyarko-san F, which is said to be short for "Final Countdown", retaining the reference.
  • The "Nyaralbum" CDs include a medley of the vocal songs from the second season called "Nyaru-Nyaru Service Medley", a nod to Macross Frontier, which had the "Nyan-Nyan Service Medley" performed over the Final Battle.
  • Nyarko's main battle theme, "Nyarko, Sanjou!", is a Suspiciously Similar Song to "Ore, Sanjou!", Momotaros' battle theme from Kamen Rider Den-O, having not only a similar name but beginning with the exact same riff before heading in a more pop-style direction (though later parts of the song do have saxophone, matching the jazzy feel of "Ore, Sanjou!")
