History Music / Tsukiuta

* SingerNamedrop: Their final performance number, "Tsuki no Uta", had them all sing lines that have wordplay corresponding to their names. Either it's the actual name used as a word, or a word that means roughly the same thing as the name. And everyone gets to sing one part of the song, meaning that each namedrop comes back-to-back-to-back after each other.

* EliteSchoolMeansEliteBrain: Hajime and Haru attended an elite high school that was the top in the nation. This school was also attended by Rui's older brother Minaduki Rei, but [[BlackSheep his situation wasn't seen as positively]] by those around him.

** [[SpaceOpera Tsukino Empire]] takes place in space civilizations, where contracts with soul beasts allow the characters to fight off unidentified mysterious invaders. [[Theatre/TsukinoEmpire Tsukista and SQS]] have had episodes in this setting.
** [[{{Youkai}} Tsukino Hyakkiyakou]], a world very close to the normal universe, where the talents are the youkai themselves. The [[AsianFoxSpirit Black and White Celestial foxes]] create the world in their slumber. [[Theatre/TsukinoHyakkiYakou Tsukista, SQS, and Ivesta]] have had episodes in this setting, and Pro-Ani season 2 also featured it.
** [[{{Steampunk}} Machine Elements, or Kisosekai]], is a world filled with mysterious ruins, with the individual units forming guilds that seek to quench their curiosity by uncovering the ruins' mysteries. [[Theatre/MachineElements Tsukista/Ivesta's gaiden and SQS]] have featured this setting.
** [[DancingIsSeriousBusiness Tsukihana Kagura]], a beautifully traditional universe that focuses on the beauty of dancing to rule, rather than using the harshness of war. [[Theatre/TsukihanaKagura Tsukista and Ivesta]] have featured this setting, as has Vazz-Ani.

** [[KatanasAreJustBetter Zanshin]], a timeline populated by [[LightIsNotGood white monsters by the name of Regret]]. Regret can only be cut down with the power of one's heart, which is represented by a sword. [[Theatre/{{Zanshin}} SQS, Tsukista, and Ivesta]] have featured this setting.

* ContinuityNod: The story takes place in a linear timeline. As a result of this, references to previous events or activities are present, though not too many that they would be distracting.

* DarkAndTroubledPast: A couple of their normal-timeline members suffer from this, but through CharacterDevelopment, they have become more fleshed out. Rui, a LonelyRichKid, suffered a deconstructed version of ParentalFavoritism, leading to him escaping home. Kai lost his [[TheLostLenore childhood friend at a young age]], and he gets hung up over it when the time of year rolls around again.

* CoverVersion: The introductory CD sets have all of the idols sing covers of traditional Japanese songs.

** Speaking of Urazanshin, the [[BigBad Zesseikyou]] talks about a whole slew of past alternate universes while musing to himself. He doesn't say the names of those worlds specifically, but he lists off a key trait of that world which would immediately tip a fan off about what he's referencing.

** Including the standard English in idol pop songs like the rest of the discography has.
** You's single "Genau!" is peppered with German, due to his [[Creator/TetsuyaKakihara voice actor]]'s skill with the language (which is actually his first). That doesn't explain the gratuitous Theatre/HenryV references in his Ani 1 solo "Happy! Phew!", though.
** The dorm pets are called "animals" in English.
** The Tsukiuta and [[Music/{{Tsukipro}} SQ]] members each have Latin fanclub names (the boy and girl for each month share theirs). The names are mostly a translation of the characters's names - e.g. Kai = Mare = Sea, Koi = Amor = Love, Tsubasa = Ala = Wing - but some mean other things.
** Shun apparently speaks about 7 languages and frequently uses this. Some of his favorite phrases are "Mou man tai" and "Que sera sera".

** Yumemigusa has Shun proclaim that he and Hajime are PurposelyOverpowered, and they can't live in too many worlds unless they want everything to collapse. Some time later, in Kurenai Enishi, Kai recalls this fact as a reason for why NeverTheSelvesShallMeet, and Shun applauds him for remembering.

* BeachEpisode: Episodes 6 and 7 serve as this for the male units, but they're prevented from getting back home because of a burnt bridge. They have to fix their residence house after a storm and try to find a radio signal to contact their peers with.

* MagicRealism: People who have only seen the anime series are often surprised by how much of the supernatural there is in the rest of this franchise.

** For the 2020 April Fools' joke, all of the mascots end up transforming into {{Notzilla}} in a Franchise/Godzilla reference.

* AnimalMotifs: Rabbits, as befitting the [[MoonRabbit lunar theme]] the project has. The rabbits themselves are owned by [[TheFaceless President Tsukino]], but they're pretty much FreeRangePets. Six Gravity keeps the large black rabbit, Kuroda, on their floor, while Procellarum keeps the tiny white lop-eared rabbit, Shiroda, on theirs. The series' mascot character, the ''Tsukiusa.'', which has a PunnyName combining moon (tsuki) and rabbit (usa), which sounds remarkably similar to the series' name Tsukiuta., is also one.

* ChildhoodFriends: Two pairs per male group: [[OrangeBlueContrast Arata and Aoi]], and [[SolarAndLunar You and Yoru]].

** Yumemigusa has Shun proclaim that he and Hajime are PurposelyOverpowered, and they can't live in too many worlds unless everything collapse. Some time later, in Kurenai Enishi, Kai recalls this fact as a reason for why NeverTheSelvesShallMeet, and Shun applauds him for remembering.

* DarkIsNotEvil: Six Gravity suits this trope completely. Their image color is black, and their leader is the "[[RedBaron Black King]]" Hajime. Their more recent idol outfits play their dark theme up more strongly, featuring black as a main color. Despite all this, Six Gravity are most definitely heroic, kind, and caring people. This becomes especially telling when they're in fits such as [[https://twitter.com/tsukiuta1/status/1446816910658576384?s=20 Zanshin]], [[https://twitter.com/tsukiuta1/status/911558123831181312?s=20 ORIGIN]], or [[https://twitter.com/tsukiuta1/status/1172503721130917888?s=20 Tsukihana Kagura]], where they're most definitely good guys while being wearing black costumes.

** [[HeavenlyBlue Aoi and Wakaba]] have refreshing and gallant personalities, fitting for May, a month that heads into summer. Aoi's a little more relaxed, exemplifying the early summer rain and Mother's Day in his songs Kalmia to Samidare and Reincarnation. Meanwhile, Wakaba is more of a go-getter, in order to beat out the May Blues as described in her third season A-side.

*** In Hajime's CD, Haru proposes that they go out because they haven't worked together recently, so he doesn't have enough Hajime in his system.

** It's stated in Iku's profile that, back when they started, Iku was TheHero to Rui, who helped him out of his shell. In order to become a man befitting of said impressive, Iku put in hard work so that he wouldn't let Rui down.
