* ActorAllusion: In the crossovers with Manga/{{Gintama}}.
** In the first episode of the anime, Switch mentions that his favorite [[Manga/{{Bleach}} Visored]] is Muguruma Kensei, who Creator/TomokazuSugita also voices. An in episode 31, Switch suggests, in Gin's voice to use a [[Manga/{{Gintama}} rather familiar]] white and black suit.
* AllStarCast: For a 2010s anime standards, the cast is full of people [[NamesToKnowInAnime well known in the industry]]. For starters, you have Creator/HiroyukiYoshino, Creator/RyokoShiraishi and Creator/TomokazuSugita as the main characters. You can extend that with Creator/TomokazuSeki, YuuKobayashi, Creator/HiroShimono, Creator/FumikoOrikasa, Creator/MarinaInoue... even from the large cast of regulars and one time characters from people like Creator/KanaHanazawa, Creator/NobuyukiHiyama, Creator/AkiraIshida and Creator/JunkoMinagawa.
* CelebrityVoiceActor: Music/{{Gackt}} as Dante.
* ExecutiveMeddling: Cherry's introduction in the manga series. Roman remarks it was a request from the editor to let there be some fanservice in the series (something that Shinohara often avoided). And oh boy, the main cast know that something is going to go wrong when he appears in it.
* FirstAppearance: With the difference of exclusive characters in both [[{{Pilot}} one-shots]], and the appearance of the Sket Dan (with minor design differences), Otakura and Yabasawa made their debuts in the first ''Akamaru Jump'' one shot, and the rest, they say, it's history.
* HeyItsThatVoice: [[Creator/RyokoShiraishi Himeko]] and [[Creator/TomokazuSugita Switch's computer voice]] are pretty much [[Manga/HayateTheCombatButler Hayate]] and [[Manga/{{Gintama}} Gintoki]]. The [[BreakTheFourthWall fourth wall will not survive.]]
** It did not -- early in the Gintama crossover manga, Gin and Switch realize they sound the same and proceed to call each other [[Creator/TomokazuSugita "Sugita"]] for the remainder of the issue. In the anime, however, both Gintoki and Switch just refer themselves as ''onii-chan''.
** For an anime series made in 2011, it has an special mention that the cast (main characters, regulars, and even one scene characters cameos) is an AllStarCast.
* MetaCasting: At some extents, Momoka, in the anime. Creator/MarinaInoue started at a young age (20 years old compared to 17-year-old Momoka) at the seiyuu and singing industry, too.
** And Dante, since Music/{{Gackt}} was one of his inspirations.
* NamesTheSame: Chiaki Takahashi, often referred as Captain who shares name with seiyuu Creator/ChiakiTakahashi... except it's not Chiaking herself (nor in voice nor shared background).
* TheOtherDarrin: As often happens when there are Drama [=CDs=] or [=VOMICs=] (manga chapters often animated with audio) before an anime series, part of the cast of regulars changed. The only ones to retain their voices were the Sket Dan, and YuuKobayashi was often changed to another character not originally voiced by her (from Reiko to Daisy).
* RelationshipVoiceActor: Some of the cast has appeared in Manga/{{Gintama}}: Creator/TomokazuSugita (Switch/Gintoki), Creator/HiroyukiYoshino (Bossun/Takachin), Creator/RyokoShiraishi (Himeko/Jugem), Creator/FumikoOrikasa (Reiko/Kyuubei), YuuKobayashi (Daisy/Saachan), Creator/DaisukeSakaguchi (Teppei/Shinpachi), Creator/SatoshiHino (Daimon/Kamui), Creator/AkiraIshida (Magarfunkle/Katsura), to mention some examples. Though the only directed in the Sket Dance/Gintama crossovers are only Sugita, Yoshino, Shiraishi... and Sakaguchi.
** Creator/TomokazuSugita and Creator/TomokazuSeki (Soujirou Agata) are self-declared rivals in real life, though they are in the same agency, founded by Seki, Atomic Monkey. Creator/FumikoOrikasa is in the same agency as well.
** Some ''Manga/JoJosBizarreAdventure'' one: KazuyukiOkitsu, Jonathan Joestar, did a minor role in the anime and he has a talk of sorts with Switch. Sugita voiced Joseph Joestar, his grandson in the TV animation series (and the All Star Battle videogame), and is a great fan of Jojo in real life as well (hence his references of the 'WRYYYY' scream in the series could be his inner fanboy as well).
** Creator/MegumiToyoguchi (Yabasawa) and Creator/MegumiTakamoto (Unyuu) were Winry Rockbell in the Fullmetal Alchemist [[Anime/FullmetalAlchemist 2003]] and [[Manga/FullmetalAlchemist Brotherhood]] incarnations respectively.
* TalkingToHimself: Happened plenty in the Sket Dance/Gintama crossovers, especially with Gintoki and Switch. And with Teppei and Shinpachi.
** Technically, Bossun's dad never interacted with his son, but his letter made it look like so in the 'Happy Birthday' episodes, and since Creator/HiroyukiYoshino was both voices (being a bit of a mythology gag from the manga), it could count as talking to himself.
