** And doesn't Yuuta's Chuunibyou persona Dark Flame Master and his "Black Flame Dragon" remind you a lot of a certain three-eyed protagonist from ''[=YuYu=] Hakusho''? He even wears [[PowerLimiter the arm bandage]].

* The episode also references Film/TaxiDriver of all movies, as seen in this [[https://www.bilibili.tv/en/video/2003546746 comparison video]]. In particular, it references Travis Bickle's arm-mounted slide for his [[CoolGun hidden gun]].

* In the first volume, pages 139 to 142, Yuuta and Rikka play video games that are heavily implied to be ''VideoGame/{{Parodius}}''[[note]]Described as "a parody shooting game" whose cast includes an octopus and [[VideoGame/AntarcticAdventure a penguin whose "other game" involves a golden apple]].[[/note]] and a bizarre non-existent spin-off of ''VideoGame/SuperSmashBros.''[[note]]Yuuta and Rikka disagree on whether the game's name is "Great Uprising" (which hews close to the series' Japanese name ''Dairantou Smash Bros.'', "Great Fray Smash Bros.") or "Sumabura" (A Japanese abbreviation of "Smash Bros.") and two of its characters is [[Franchise/{{Pokemon}} a yellow mouse with electric attacks]] and [[VideoGame/{{Kirby}} "the Pink Demon"]], yet it's explicitly mentionned as being a war game and not a beat-'em-up game, and the gameplay involves cutting up trees (impossible in ''Smash Bros.'' at the time the novel was written) ammo (only items in ''Smash Bros.'' use ammo, and Rikka says that the match they're playing has items disabled.) and meteor rain attacks (the only characters to have those are [[VideoGame/{{Earthbound}} Ness]] and [[VideoGame/{{Mother 3}} Lucas]] in ''Brawl'', who can only use them with a Final Smash, which can only be obtained through items...).[[/note]]

* Perhaps just a GagSub, but episode 2 has Rikka saying "[[VideoGame/TheLegendOfZelda It's dangerous to go by yourselves. Take this.]]" while [[http://www.lolcats.com/popular/19863-its-dangerous-to-go-alone-take-this.html holding out a cat.]]

* Although slight, Sanae says, "That's the duty of those bound by contract!", which sounds a lot like ''Anime/PuellaMagiMadokaMagica''.

* In the first volume, page 62, Yuuta mentions that Rikka's personal term for e-mails sounds like it came out of [[LightNovel/ACertainMagicalIndex Academy City]].

* Sanae performs the incantation for the [[FantasticNuke Dragon Slave]] by [[LightNovel/{{Slayers}} Lina Inverse]]. She specifically chants the first, second, and last line of Lina's FinishingMove, including the actual name of the spell (just in case you didn't catch it).

* Meanwhile, Rikka Takanashi herself doesn't only parody the EyepatchOfPower found on numerous anime girls like Mei Misaki from ''Literature/{{Another}}'' or Najenda from ''Manga/AkameGaKill'' (Megumin from ''LightNovel/KonoSuba'' came later). She's also a reference to Hiei, particularly the aspect of him that involves covering up one of his eyes (his "Jagan" or "Evil Eye") to seal its power. In her case, she's covering up her "Jaou Shingan" or "Tyrant's Eye", with its name also referencing Hiei's most powerful special attack.

* Yuuta is playing ''VideoGame/MonsterHunter'', though admits that he's been out of practice in the game.

* In episode 9 of season 2, Rikka's attack scene shouts out many mecha references, including entry plugs and primary locks disengaging from ''Anime/NeonGenesisEvangelion'', "I will believe in the me that Yuuta believes in!" from ''Anime/GurrenLagann'', and mechas that appear inspired by ''Anime/MobileSuitGundam''.
