"I'm going to finish first!" (0:29) "Huh? I can't drift!" (0:32) "Who just threw that shell?" (0:35) "The banana! The banana!" (0:39) Nyaruko and company are playing "Mario Kart", a series of racing games starting with "Super Mario Kart", released for the SNES in 1992. Drifting is one element of the game controls. Shells are items that can be picked up during the race and thrown at other racers to temporarily stun them. Bananas are also items in the game that can be picked up. Bananas are dropped on the race track as traps and if a racer drives into a banana he will spin out of control. Here is a video showing each of these gameplay elements:

(0:33) The controllers that Nyaruko and company are using are based on the controller for the Nintendo 64. Taking this into consideration, it's likely that they are playing "Mario Kart 64", the second installment in the "Mario Kart" series released for the N64 in 1996. N64 controller image for reference:

"Ghutatan!" (1:51) "This is the young lady of the Ghatanothoa Conglomerate, Ghutatan." (2:05) There are four references here: * Ghutatan and the Ghatanothoa Conglomerate are based on Ghatanothoa, a fictional deity in the Cthulhu Mythos that first appeared in "Out Of The Aeons", a short story written by H. P. Lovecraftand Hazel Heald and first published in 1935. * The name Ghutatan (グタタン Gutatan) is based on "G'tanta" (グタンタ Gutanta), another name Ghatanothoa is known by that is mentioned in "Out of The Aeons". (Thanks servitors for info) * Ghutatan's pose here with her hand raised is likely referencing Akaza Akari who makes this pose at the beginning of most episodes of "YuruYuri", an anime that aired in 2011. The connection here is that the person who voices Ghutatan, Mikami Shiori, also voices Akari. Image for reference:

* Ghutatan's spiral hair style seems to be referencing the appearance of a monster from the Japanese TV show "Ultraman Tiga", Gatanozoa (ガタノゾーア), who has a spiral-shaped shell. In addition, Gatanozoa is based on Ghatanothoa from the Cthulhu Mythos.S1 Image for reference:

"I nyow!" (5:00) "I nyew it." (5:31) The Japanese dialogue is "Nyaruhodo!" (にゃるほど!). This is using the Japanese term "naruhodo" (なるほど), which generally means "I understand", and changing the sound of the first syllable to "nya" to make it sound Nyaruko-like. "Nyaruhodo" is an often used word on "Nyaruraji" (にゃるラジ), a web radio show about "Haiyore! Nyaruko-san" that is hosted by Asumi Kana and Matsuki Miyu, the voice actors of Nyaruko and Cthuko respectively.S2 For example, the word was mentioned in episodes 3, 4, and 6 of "Haiyoru Nyaruraji -OMEGA-" (這いよるにゃるラジ-OMEGA-), the second season of the web radio series that aired in 2010.

(5:04) There are two references here: * Nyaruko's pose on the left is referencing that of Amano Touko on the cover of "Bungaku Shoujo to Shinitagari no Piero" (“文学少女”と死にたがりの道化【ピエロ】), localized as "Book Girl and the Suicidal Mime".

Yuno is a high school student who is attending an art school and dreams of being a great artist. In the anime adaptation of "Hidamari Sketch" she is voiced by Asumi Kana, the same voice actor who voices Nyaruko.S1 * "Nudists" is referencing Kitahara Mio from "Ano Natsu de Matteru", an anime that aired in 2012. Mio is a nudist and is also voiced by Asumi Kana.S1

"Lost Girl from the Stars" (5:52) The Japanese title is "Hoshi kara otozureta mayoigo" (星から訪れた迷い子). This is referencing "The Shambler from the Stars" (星から訪れたもの hoshi kara otozureta mono), a Cthulhu Mythos short story written by Robert Bloch and first published in 1935. In the story there is a creature called Star Vampire that is also known as "shambler from the stars".

(6:00) There are two references here: * The creatures that appear here are Shoggoths, a species of creature in the Cthulhu Mythos. "It was a terrible, indescribable thing vaster than any subway train—a shapeless congeries of protoplasmic bubbles, faintly self-luminous, and with myriads of temporary eyes forming and unforming as pustules of greenish light all over the tunnel-filling front that bore down upon us...".S6On a related note, the Shoggoths repeatedly say "Tekeli-li", which is referencing how Shoggoths are known to endlessly repeat this phrase in the Cthulhu Mythos. * The Shoggoths are on a roof. This is referencing "A Shoggoth on the Roof", a musical published by the H. P. Lovecraft Historical Society in 2005 that is based on the works of Lovecraft and is a parody of the musical "Fiddler on the Roof".S1

(6:13) This is the same game that appeared in episode 1 at 7:36. There are three references here: * The cover art of the package is based on that of the second volume of "Makai Shoujo Ruruie Ruru" (魔海少女ルルイエ・ルル). Image for reference:

Source of image: * The title of the game is

"Koi Suru Jashin ha Setsunakute Onii-chan wo Suuhai Suru to Sugu Ia Ia Shichau no"
"It's Hard to be an Evil God in Love, When I Worship Brother I Immediately Ia Ia"
"Ia Ia" is a common chant phrase from the Cthulhu Mythos which means "Yes! Yes!". A well known example is "Ia! Ia! Cthulhu fhtagn!", a chant worshiping Cthulhu which means "Yes! Yes! Cthulhu dreams!". The title as a whole is based on
"Koi Suru Imouto ha Setsunakute Onii-chan wo Omou to Sugu H Shichau no"
"It's Hard to be a Little Sister in Love, When I Think of Brother I Immediately Get Aroused"
This is the title of an adult game released by CAGE in 2003. * The creature that the girl on the cover is hugging is a Mi-go, a species of creature in the Cthulhu Mythos. In "The Whisperer in Darkness", a short story written by H. P. Lovecraft and first published in 1931, it is stated, "They were pinkish things about five feet long; with crustaceous bodies bearing vast pairs of dorsal fins or membraneous wings and several sets of articulated limbs, and with a sort of convoluted ellipsoid, covered with multitudes of very short antennae, where a head would ordinarily be."

"Then I'll make us a good morning breakfast!" (7:41) The Japanese dialogue is "Jaa, boku ga ohayou asa gohan wo yoi suru yo" (じゃあ、僕がおはよう朝ご飯を用意するよ). This is referencing "Ohayou!! Asa Gohan" (おはよう!!朝ご飯), or "Good Morning!! Breakfast", a song sung by Takatsuki Yayoi in the game "THE IDOLM@STER".S2 On a related note, Hasta's voice actor, Kugimiya Rie, also voices Minase Iori, another character from "THE IDOLM@STER".

(8:04) The text on the package reads "Dagon Yooguruto" (ダゴン ヨーグルト), or "Dagon Yogurt", which is a reference to Dagon, a sea dwelling creature and a servant of Cthulhu in the Cthulhu Mythos.S1 Here is an isolation that might be easier to read:


"They're insects from Shaggai." (8:07) Insects from Shaggai are a species of creature from the planet Shaggai in the Cthulhu Mythos.   

"Mirror of Nitocris!" (8:43) There are three references here: * The Japanese dialogue is "Cha ra ra cha ccha ra! Nitokurisu no Kagami!" (チャララチャッチャラ!ニトクリスの鏡!). The way in which Nyaruko unveils the mirror is referencing Doraemon from "Doraemon", a manga written by Fujiko F. Fujio and published from 1969 to 1996.S1 When Doraemon unveils a new gadget, often he will hold it up and say the name of the gadget, and the background will be drawn with an emphasizing effect. Image for reference:

In anime adaptations of "Doraemon", typically a musical chime sound effect will be played when Doraemon unveils the gadget, which is what Nyaruko's singing is referencing. * The appearance of the mirror is based on that of a magical compact mirror used by Kagami Atsuko, also known as Akko, in "Himitsu no Akko-chan", a manga written by Akatsuka Fujio and published from 1962 to 1965.S1 Images for reference: 

Image sources: * Nitocris is an Egyptian Pharaoh, though it is unclear is she truly existed or not. In the Cthulhu Mythos, Nitocris is described as an evil Egyptian queen. The Mirror of Nitocris appears in "The Mirror of Nitocris", a Cthulhu Mythos short story written by Brian Lumley and first published in 1971. The mirror once belonged to Nitocris and possesses mystical powers that enable its viewer to glimpse forbidden sights. It is described as "a 'gateway' to unknown spheres and worlds of hellish horror in the shape of a mirror."S10 Also, within the mirror dwells a blob like entity that can emerge from the face of the mirror at midnight.

"A thing, a bubbling blasphemous shape from lunacy's most hellish nightmare, was squeezing its flabby pulp out through the frame of the mirror into my room—and it wore a face where no face ever should have been."S10
When the creature emerges, it will attempt to drag anyone nearby into the mirror in order to consume them and absorb their souls.S5,S10

"It passed the Space ISO 9001 quality standard!" (9:17) This is referencing the ISO 9001 standard, a standard of quality published by the International Organization for Standardization, abbreviated as ISO. ISO 9001 certification is granted to a company that meets the required standards. The certification requirements are intented to facilitate a good standard of quality management in companies.

"Oh? Mahiro, did you look at my Pretty Rhyth-" (9:32) What Nyaruko was about to say is "Pretty Rhythm", which is referencing the game by that namereleased in 2010. It was adapted into an anime called "Pretty Rhythm: Aurora Dream" in 2011. In the anime, the main character, Harune Aira, is voiced by Asumi Kana, who also voices Nyaruko.

"Gyafun!" (9:48) Like in episode 5 at 8:49, when Nyaruko falls over she says "Gyafun!" (ぎゃふん!), which is a line often said by Harune Aira, the main character of the anime "Pretty Rhythm Aurora Dream". The connection is that Aira is also voiced by Nyaruko's voice actor, Asumi Kana.S1 Video for reference (nicovideo requires an account to view):

(11:39) Nyaruko's pose is referencing that of Aihara Nana (相原 菜々) from "KimiKiss" (キミキス), a dating simulation game released by Enterbrain (エンターブレイン) in 2006.S2 Image for reference:

Source of image: The connection here goes as follows: - Nana is the younger sister of the main protagonist in "KimiKiss". - The company that developed and published "KimiKiss", Enterbrain, also developed and published "Amagami" (アマガミ), which was released in 2009. "Amagami", like "KimiKiss", is also a dating simulation game that takes place in a high school setting. In addition, both "Amagami" and "KimiKiss" share the same character designer, Takayama Kisai (高山箕犀). As a result, the games are similar to each other in terms of gameplay and visual appearance. - In "Amagami", there is a character named Tachibana Miya (橘 美也), who is the younger sister of the main protagonist. - Nyaruko's voice actor, Asumi Kana (阿澄佳奈), also voices Miya in "Amagami". However, she does not voice Nana in "KimiKiss". Nana is voiced by Nogawa Sakura (野川さくら). - Nyaruko's line at this time goes, "Deko chuu, deko chuu, to misekakete!" (デコちゅー、デコちゅー、と見せかけて!), which translates to "A kiss on the forehead, a kiss on the forehead, just pretending!". "Deko chuu" (デコちゅー), "kiss on the forehead", is referencing a line said by Nana. Her line goes, "Deko chuu shite!" (デコちゅ~してっ!), which translates to "Give me a kiss on the forehead!". Nyaruko states that she is "just pretending", which relates to how her pose and spoken line are not referencing a character voiced by Asumi Kana, but instead are referencing Nana. Putting it all together, Nana is similar to Miya, who is voiced by Asumi Kana, both characters appear in games that have similar gameplay and appearance, and both games were developed and published by the same company.

(11:44) The creature in Ghutatan's hair is a depiction of her base character, Ghatanothoa. It is described as "gigantic—tentacled—proboscidian—octopus-eyed—semi-amorphous—plastic—partly squamous and partly rugose...".S7

(12:00) The maids that appear here are based on an illustration on page 271 of volume 6 of the "Haiyore! Nyaruko-san" light novel.S3 Image for reference:

On a related note, the maid that appears here is based on Tekeri, the main character of "Uchi no Meido ha Futeikei" (うちのメイドは不定形), "My Maid is Amorphous", a Cthulhu Mythos inspired light novel written by Shizukawa Tassou (静川龍宗) and published in 2010. Images for reference: 

In addition to the visual similarity, the connection is made clear by the following dialogue on page 270 of volume 6 of the "Haiyore! Nyaruko-san" light novel.S9 When Cthune (クー音 Kuune), Cthuko's cousin, shows off what she bought, she says,

「どう、これ! すごいでしょ! 『テケリ』だよ! 地球の日本、それも蜷川区でしか配信されない伝説のモンスターなんだよ!」

"What do you think of this! Isn't it amazing! It's 'Tekeri'! It's a legendary monster that isn't sold anywhere except in the Ninagawa Ward of Japan on Earth!"
To explain, in "Uchi no Meido ha Futeikei", Tekeri is a shoggoth from the Cthulhu Mythos. In "At the Mountains of Madness", a story written by H. P. Lovecraft and first published in 1931, a shoggoth is described to be "a shapeless congeries of protoplasmic bubbles". This is why Tekeri is described as "futeikei" (不定形), "amorphous", in the title. Her name is based on "Tekeli-li", a phrase shoggoths are known to endlessly repeat in the Cthulhu Mythos. Ninagawa Ward (蜷川区 Ninagawa-ku) is the name of the fictional city that is the setting of this light novel.

"It's very important, so I asked twice!" (13:37) The Japanese dialogue is "Daiji na koto nano de nikai iimashita!" (大事なことなので二回言いました!). This is a repeat of a reference in episode 1 at 11:14. This is referencing a popular Japanese TV commercial for the health product "Jokin ga Dekiru Tafudento" (除菌ができるタフデント), or "Bacteria Eradicating Tough Dent", tablets used for cleaning dentures sold by the Kobayashi Pharmaceutical Company (小林製薬株式会社). The original line goes, "Daiji na koto nano de nidai iimashita yo" (大事なことなので二度言いましたよ), or "I said it twice because it's important!". Video reference:

* The girl says "Chii suutaro ka" (血ぃ吸うたろか), which roughly means "Shall I suck your blood?". This is a gag line used by Japanese comedian Hazama Kanpei (間寛平).S2

Radio playing in the background (15:30) The radio show that can be heard playing in the background during this entire scene is an excerpt from an episode of the Japanese radio show "A&G; SUUPAA RADIO SHOW ~AniSupa!~" (A&G; 超RADIO SHOW〜アニスパ!〜). The excerpt is of the hosts of the show reading a letter submitted by a listener going by the pen name "Ni dai me bishoujo" (二代目美少女), or "Second Generation Beautiful Girl". It has been revealed that this letter was actually sent in by Matsuki Miyu, the voice actor of Cthuko. On a related note, Asumi Kana, Matsuki Miyu, and Ootsuba Yuka, the voice actors of Nyaruko, Cthuko, and Tamao, guest star on episode 425 of "AniSupa", which aired on May 26, 2012.S2 Here is a related article for reference (Japanese):

(15:31) As mentioned in episode 7 at 9:49, there are two references here: * The name of Luhy's grilled octopus stand is Puti Kuti (プティ・クティ). This is referencing the mascot character by that name from the book "Moe Moe Kutouruu Shinwa Jiten" (萌え萌えクトゥルー神話事典), a Cthulhu Mythos Encyclopedia.

"They're lost Shoggoths." (17:06) "Weak and quick to run. An extremely rare character." (17:08) "This is an opportunity to gather experience points!" (17:22) The term "hagure shogosu" (はぐれショゴス), or "lost Shoggoths", is referencing "hagure metaru" (はぐれメタル), or "lost metal", a monster that appears in the "Dragon Quest" game series and first appeared in "Dragon Quest II". It is also known as Metal Babble and Liquid Metal Slime in localizations. Like Cthuko says, Liquid Metal Slime has low health, often immediately runs away when encountered, and appears very rarely. In accordance with what Nyaruko says, Liquid Metal Slime also gives out a large amount of experience points when it is defeated.

"Cyclone... Metal..." (17:13) There are two references here: * "Metal" is referencing the aforementioned Liquid Metal Slime from the "Dragon Quest" game series. * "Cyclone" and "Metal" are referencing the CycloneMetal form of Kamen Rider W from "Kamen Rider W". In addition, the colors of the Shaggoths match the half green and half silver color scheme of Kamen Rider W's CycloneMetal form.S1 Image for reference:

"Spew your guts!" (17:50) The Japanese line is "Harawata wo buchimakenasai!" (腸をぶちまけなさい!). This is referencing a line said by Tsumura Tokiko (津村斗貴子) in "Busou Renkin" (武装錬金), "Arms Alchemy", a manga series written by Watsuki Nobuhiro (和月伸宏) and published from 2003 to 2006.S1 Her line goes, "Zoumotsu wo buchimakero!"

"Fire power up, Fever." (18:21) The Japanese dialogue is "Karyoku appu fiibaa" (火力アップフィーバー). This is referencing Kamen Rider Kiva's "Wake Up Fever" (ウェイクアップフィーバー Weiku Appu Fiibaa) attack in "Kamen Rider Kiva".S3

Nyaruko's tune (18:32) The tune that Nyaruko sings at this time is the level up sound effect in the "Dragon Quest" game series. Video for reference:

(18:50) Ghutatan's lying down state is referencing that of Yamcha in chapter 215 of volume 18 of "Dragon Ball", a manga series written by Toriyama Akira and published from 1989 to 1995.S1 The series was later republished in 2002 as 34 volumes, rather than the original 42.
