"Yahoo!" (4:44) This scene is a reference to the "Super Mario" game series. The question mark block and brick blocks are staples of the series, and Nyaruko's jumping pose is mimicking that of Mario. Nyaruko also says Mario's signature "Yahoo!" catch phrase.

(5:17) Nyaruko's expression is referencing the anime adaptation for the visual novel, "Higurashi no Naku Koro ni". The crazed face with small pupils and a wide smile is a commonly occuring expression in the anime. Image for reference:

(5:23) There are two references here: * Nyaruko's expression is referencing the Fujiya Food Service Co. and their mascot Peko-chan. Image for reference:

"Blue Coral Reef" (6:02) As mentioned last episode, the Japanese title is "Aoi Sangoshou" (青い珊瑚礁), or "Blue Lagoon", which is referencing the novel "The Blue Lagoon", which inspired several movie adaptations and a song by that name sung by Matsuda Seiko. The title is also a pun on "SAN", or sanity points, from the "Call of Cthulhu" role playing game.  

"Whoops, there's a teleporter here!" (6:44) "He almost ended up in a rock." (6:53) There are two references here: * The lines are referencing the role-playing video game series "Wizardry" and the Teleport Trap, a recurring trap in the series. A Teleport Trap is hidden in a treasure chest and, when triggered, teleports the party away from its current location to any other square on the same level. Nyaruko's second line references the possibility of the party teleporting to a square occupied by solid rock, which results in the death of the party. Specifically, her first line goes, "Ootto, konna tokoro ni terepootaa gaa!" (おおっと、こんな所にテレポーターがぁ!). "Ootto! terepootaa" (おおっと!テレポーター), or "Whoops! A telepoter", is a possible message that can appear when the player discovers a Teleport Trap. Nyaruko's second line goes, "Mou sukoshi de ishi no naka ni iru tokoro deshita yo" (もう少しで石の中にいるところでしたよ). "Ishi no naka ni iru" (いしのなかにいる), or "You are in a rock", is a possible message that can appear when the party dies in the above mentioned scenario.S1Images for reference: 

Image sources: On a related note, the Necronomicon from the Cthulhu Mythos appeared in "Wizardry IV: The Return of Werdna", the fourth game in the "Wizardry" game series.S4 * Nyaruko's stance is that of Tetsuzankou (鉄山靠), a technique that attacks the target with one's shoulder. It is a part of a Chinese style of martial arts called Bajiquan (八極拳), or Hakkyokuken as it is called in Japanese. In particular, Nyaruko's form is mimicking that of Yuuki Akira, a character from the "Virtua Fighter" game series, who popularized the technique and its form with his use of it in the very first "Virtua Figher", which was released in 1993.S1 Image for reference:

On a related note, in Chinese the technique is written as 「貼山靠」, or Tie Shan Kao, and the original form is slightly different. Video for reference:

"Our True End Route has no detours!" (7:02) This is referencing a common element in visual novels. Many visual novels have multiple story routes that the player can read through. Also, visual novel will often have multiple endings, ranging from good to bad.

This is referencing the beach house by that name that appears in the manga "Yuri Seijin Naoko-san" (百合星人ナオコサン).S1,S2 Image for reference:

Source of image: * The girl that walks past behind Cthuko is Jashin-chan (邪神ちゃん). "Jashin" literally translates to "malign deity" or "evil god" and is the same term used to describe such entities in the Cthulhu Mythos like Nyarlathotep and Cthulhu. Jashin-chan is also from "Yuri Seijin Naoko-san" and works at the above mentioned beach house. In the series, she was originally sealed in a temple at the bottom of the sea before she was released in chapter 17, which is similar to how Cthulhu is imprisoned in sunken city of R'lyeh in the Cthulhu Mythos.S1,S2 Image for reference:

"Setting my flag will not work." (9:33) There are two references here: * As mentioned last episode, the flag that appears to the left of Cthuko is referencing the Special Flag from "Rarii-X" (ラリーX), localized as "Rally-X", an arcade game made by Namco and first released in 1980. In the game the player drives a blue car through a maze. The goal of each stage is collect all 10 flags scattered throughout the maze while avoiding other cars. Obtaining the Special Flag will double the points received for each flag collected after until the player dies. Image for reference:

Source of image:,403849/ * As mentioned in episode 5, the "flag" Cthuko mentions is referencing a common element in visual novels. Often times in such games there will be decision points at which the player has to choose how to proceed. Certain decisions, at times a series decisions, of will cause a "flag" to get set which will later cause an event to occur.

(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.S4 Amazon link (not safe for work cover): click to view * The creature that appears on the sign is the famed Cthulhu from the Cthulhu Mythos. Cthulhu is described as, "... a monster of vaguely anthropoid outline, but with an octopus-like head whose face was a mass of feelers, a scaly, rubbery-looking body, prodigious claws on hind and fore feet, and long, narrow wings behind."S5 In particular, however, the depiction is based on the appearance of Puti Kuti from the aforementioned book.S4 Image for reference:

"Cthulhu and Hastur have never gotten along." (10:45) As mentioned in episode 6 at 7:31, this is referencing how Cthulhu and Hastur are antagonistic towards each other in the Cthulhu Mythos. Evidence of opposition between the two is mentioned in various texts, such as "The Return of Hastur", a short story written by August Derleth and first published in 1939, and "The Trail of Cthulhu", a book containing a series of interconnected short stories written by August Derleth and first published in 1962.

(11:22) There are two references here: * As mentioned above, the creature depicted is Cthulhu from the Cthulhu Mythos and its appearance is based on that of Kuti Puti from "Moe Moe Kutouruu Shinwa Jiten". * The Japanese text reads "Ia, Ia" (いあ、いあ). As mentioned in episode 1 at 3:20, the phrase "Ia! Ia!" is a common chant 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!".

(11:50) Mahiro's pose in this scene is mimicking that of Kazari Shokunin no Hide (飾り職人の秀), Decorations Craftsman Hide, from "Hissatsu Shigotonin" (必殺仕事人), roughly "Working Men Killers", a Japanese TV drama that aired from 1979 to 1981 and is part of the "Hissatsu" series (必殺シリーズ), or "Certain Kill" series.S2

"Judgement time!" (11:52) There are two references here: * The Japanese dialogue is "Jajjimento Taimu!" (ジャッジメントタイム!). This is a reference to the Japanese TV show "Tokusou Sentai Dekaranger". "Judgement Time" is a phrase used when the Dekarangers use their SP Licenses to contact the ultimate court in the universe which then passes judgement upon an enemy Alienizer.S1 * "Judgement time!" is also a phrase used in song "Middonaito Dekarenjaa" (ミッドナイト デカレンジャー), or "Midnight Dekaranger", the ending theme song to "Tokusou Sentai Dekaranger". The stars flying into the foreground mimics the same effect in the ending sequence to "Tokusou Sentai Dekaranger".S3 Image for reference:

Video for reference:  

"Mahiro, you're as brilliant as the sun. You're bold and invincible!" (12:27) The Japanese dialogue is "Mahiro-san ttara nichirin no kagayaki, motoi daitaan desu ne!" (真尋さんったら日輪の輝き、もといダイターンですね!). Nyaruko's use of the word "daitaan" (ダイターン) is a pun on 「大胆」, pronounced "daitan", which means "daring" or "bold", and 「ダイターン」, pronounced "daitaan", the name of a solar-powered super robot from the anime "Muteki Kikoujin Daitaan 3" (無敵鋼人ダイターン3), or "Invincible Steel Man Daitarn 3". The phrase "nichirin no kagayaki" (日輪の輝き), or "radiance of the sun", is referencing a catch phrase from the show said by Haran Banjou, Daitarn's pilot.S1 Bajou's line goes as follows:

"Yo no tame hito no tame, meganoido no yabou wo uchikudaku daitaan surii! Kono nichirin no kagayaki wo osorenu no naraba, kakatte koi!!"
"For the sake of the world and the people, Daitarn 3 exists to crush the ambitions of the Meganoids! If you don't fear the radiance of the sun, then bring it on!!"

"I will break the watermelon apart with my kicks and martial arts." (12:37) There are two references here: * "Kick" and "Martial Arts" are recurring skills in various "Call of Cthulhu" role playing games.S2Skills list from the "Call of Cthulhu" 5th edition rulebook for reference. * The Japanese dialogue is "Kikku to maasharu aatsu de suika wo keriwarimasu ne" (キックとマーシャルアーツでスイカを蹴り割りますね). This is referencing a line said by Higuchi Sayaka (樋口さやか) in "Ruruie Antiiku" (るるいえあんてぃーく), "R'lyeh Antique", an RPG replay book based on the "Call of Cthulhu" RPG that was written by Uchiyama Yasujirou (内山靖二郎) and published in 2009.S4Sayaka's line goes:

Sayaka: Tsugi ha watashi no ban desu ne. Eeto, watashi ha "kikimimi" de minna no shiji wo yoku kiite "kikku" to "maasharu aatsu" de suika wo keriwarimasu!
Sayaka: It's mine turn next, huh? Um, I'll "listen" really closely to everyone's instructions, and break the watermelon apart with my "kick" and "martial arts"!
Image for reference:

Source of image: The context for the above scene is that Sayaka and company are playing a popular Japanese beach game in which one participant is blindfolded and usually armed with a bat or a stick. He or she is then directed towards a watermelon by the other participants and attempts to break the watermelon apart. As a side note, "Listen" is another skill from the "Call of Cthulhu" RPG, which is why it is in quotes.  

"Because we're like two wings of a bird." (12:57) "We're like two trees that have grown into each other." (13:07) There are four references here: * The Japanese dialogue for the first line is "Watashi to Mahiro-san ha hiyoku no tori desu shi" (私と真尋さんは比翼の鳥ですし). "Hiyoku no tori" (比翼の鳥) is a Japanese expression that refers to a pair of male and female birds that always flying together and is used to describe a happily married couple. There are various interpretations of the expression, all holding the meaning of togetherness, such as each bird having one eye and one wing such that together they make a whole or the pair being a single bird having two heads. * The Japanese dialogue for the second line is "Watashi to Mahiro-san ha renri no eda desu shi" (私と真尋さんは連理の枝ですし). "Renri no eda" is a Japanese expression that refers to trees with entwined branches and is used to describe an intimate relationship between lovers. * The above two expressions can be put together to form the term "hiyokurenri" (比翼連理), which is used to mean "marital vows".S2 * These lines are referencing a line said by Al Azif in "Zanma Taisei Demonbein" (斬魔大聖デモンベイン), localized as "Deus Machina Demonbane", a Cthulhu Mythos inspired visual novel released by Nitroplus in 2003.S2 Al Azif is the original version of the Nercronomicon, in the setting copies exist, and takes the appearance of a young girl. She was written by Abdul Alhazred, the character from the Cthulhu Mythos who wrote the Necronomicon. Her name, "Al Azif", is the original name of the Necronomicon in the Cthulhu Mythos. Her original line goes as follows:

"Warera ha senyuu. Warera ha meiyuu. Warera ha hiyoku no tori. Warera ha renri no eda."
"We are comrades. We are sworn friends. We are two halves of a whole. We are inseparable."

"Sorry, there won't be any wardrobe malfunctions!" (14:08) The Japanese dialogue is "Porori ha nai yo!" (ポロリはないよ!), which more literally means "There will not be any swimsuits falling off!". This is a reference to the Japanese variety show "Doki! Marugoto Mizugi! Onna Darake no Suitei Taikai" (ドキッ!丸ごと水着!女だらけの水泳大会). On the show the participants will wear swimsuits and play various games at a pool. The catch phrase "Porori mo aru yo!" (ポロリもあるよ!), or "There will also be swimsuits falling off!", was once used on the show. It has since become a popular phrase.S1

"The rats in the walls... The window... the window..." (14:25) "The Rats in the Walls" is a short story written by H. P. Lovecraft and first published in 1924. "The window! The window!" (窓に!窓に! Mado ni! Mado ni!) are the last words written in "Dagon", a short story written by H. P. Lovecraft and first published in 1919.S1

"Nyarlko's sanity points have almost reached zero!" (14:31) As mentioned in episode 1 at 4:49, sanity points, abbreviated as SAN, are a parameter that characters have in the "Call of Cthulhu" role playing game. If a character's sanity points drop to zero, the character is permanently insane and typically can no longer be played. The sanity table from the "Call of Cthulhu" character sheet also appears here. On a related note, Nyaruko's sanity points are at 3 in the scene, which is a pun on SAN since the number 3 in Japanese is pronounced "san". Here is a character sheet from the rulebook for the 5th edition of the "Call of Cthulhu" RPG for reference:

Background music (14:47) The song that plays at this time is referencing "Taboo" (タブー Tabuu), a song played in a collection of skits performed by Japanese comedian Katou Cha (加藤茶) of "The Drifters" (ザ・ドリフターズ Za Dorifutaazu), a Japanese comedy group. The song also plays in episode 3 at 16:48. For a more detailed explanation, please check the explanation on the episode 3 post.

"... with a technique only I can use." (14:47) The Japanese dialogue is "Watashi dake ga tsukaeru tekunikku de, tokashi tsukushite" (私だけが使えるテクニックで、溶かしつくして). This phrase is a parody of a line from the lyrics to the song "Eejento Yoru wo Yuku" (エージェント夜を往く), or "The Agent Departs at Night", from the game "The Idolmaster". The original line goes, "Anata dake ga tsukaeru tekunikku de tokashi tsukushite" (あなただけが使えるテクニックで溶かしつくして), or "With the technique only you cane use, melt me!". In particular, the phrase "tokashi tsukushite" (溶かしつくして) has become very popular.S1 Video for reference:  

"Mahiro said I'm not his sweetheart. He said 'you're not minesweeper'." (15:43) "I think you misheard something there." (15:47) Nyaruko's line is related to when, at 13:39, Mahiro says, "You're not my sweetheart". The Japanese dialogue is "Kirai da zo" (嫌いだぞ), which more literally means "I dislike you". Here Nyaruko says, "Mahiro-san ga kirai tte, eigo de ui to main" (真尋さんが嫌いって、英語で言うマイン), which more literally means "Mahiro said 'dislike', 'mine' in English". This is a pun since the same pronunciation "kirai" is used for both 「嫌い」 to mean "dislike" as well as 「機雷」 to mean "mine", the explosive weapon. Mahiro follows up to say "Sore ha kirai da" (それは機雷だ), or "That's a mine".S2 The image that appears next to Mahiro is of "Minesweeper", a game in which the player tries to uncover all the mines hidden on the game board without setting any off. Image for reference:

On a side note, the "Minesweeper" board that appears in the scene is depicting the scenario of the player losing on the very first move of the game, which is impossible in a standard game of "Minesweeper". Here is a website describing the first click behavior of Windows "Minesweeper":

~< `-ω-´> (17:30) Aisora sighting #4.

(17:55) The tower that appears here is based on the Black Stone, which first appeared in "The Black Stone", a short story written by Robert E. Howard and first published in 1931.

"It was octagonal in shape, some sixteen feet in height and about a foot and a half thick. It had once evidently been highly polished, but now the surface was thickly dinted as if savage efforts had been made to demolish it; but the hammers had done little more than to flake off small bits of stone and mutilate the characters which once had evidently marched in a spiraling line round and round the shaft to the top."S7
In the story, the Black Stone is revealed to be "a spire on a cyclopean black castle."S7 The tower that appears here bears great resemblance to a depiction of the Black Stone that appears in "Kutourufu Shinwa Gaidobuuku" (クトゥルフ神話ガイドブック), or "Cthulhu Mythos Guidebook".S4Image for reference:
