Tsukiuta。 is a project under the fictional Tsukino Talent Productions agency, a group of Vocaloid and Niconico producers working together to produce songs for individual characters. Beginning in 2012, it consists of four idol units representing the months of the year, with the male half of the project being the main focus. The men came first in 2012, while the women debuted in 2014.

The groups are as follows:

  • Six Gravity (male) and Fluna (female), for December-May
  • Procellarum (male) and Selas (female), for June-November

For the most part, the franchise consists of albums and Drama CDs, each explaining the characters and their motivations more clearly. An anime about the male groups, Tsukiuta the Animation, aired in the Summer 2016 Anime season animated by Studio Pierrot, while a mobile Rhythm Game, Tsukino Paradise, debuted in 2017. A second anime season was announced at Animate Girls Festival 2018, this time focusing on the 2019 era of Tsukiuta and produced by Children's Playground Entertainment. This season would not air until Fall 2020 due to delays. The Tsukitsui Yonkoma manga began around the same time in 2016, and ran on the webcomic host Yuruyon.


There is also an ongoing stage play series that started in 2016, with multiple plays every year since. Most of them are done with two sides in repertory, a "black" side focusing on the Six Gravity members, and a "white" side focusing on the Procellarum members.

The cast also performs separate concerts: Lunatic Live in 2017, Memorial Tour in February and March 2018, and Lunatic Live in Omiya in December 2018 (together with the cast of SQS). In contrast to the drama CDs and anime, the stage plays often feature fantasy AU stories with elaborate costumes. The final performances of each play are filmed for bluray.

The characters play minor roles and sometimes cameo in the other Tsukipro series, including Tsukipro the Animation as the sempai groups of all of the main characters in that adaptation.


The franchise provides examples of:

  • Alice Allusion: An Alice in Wonderland retelling happens in one of the Drama CDs, with all the boys acting the part of the characters.
  • All Animals Are Domesticated: Hand-waved? Justified? Averted? The penguin and panda are magical, which is how they can live in a dorm with humans and not need special food or temperatures. As for the palm-sized reindeer, well, he's actually a fairy.
  • All There in the Manual: Part of why it's so hard to get into - there's way more manual than main story. There isn't really even one "main story" - there's the drama CDs, but they don't make up the majority of what's been made, either. If you're interested, starting with the anime wouldn't be a bad idea. Just keep a wiki on hand for reference!
  • Animal Motifs: Rabbits, as befitting the lunar theme the project has. Procellarum has a small white pet rabbit and Six Gravity has a big black one, and the Mascot, the Tsukiusa, is also one.
  • Audience Participation Song:
    • Gravitic Love's chorus - "So Fast!" "So Vast!"/ "So High!" "Turn Round!"
    • During the dance portions of the stage plays, during "tsukinouta", fans will call out the characters' names at their line in the Singer Namedrop song.
  • Bare Your Midriff: Almost everyone has a bit of this area showing in the Origins AU, whether that's cutouts on the side like Aoi has, or a costume like Kakeru's with more fabric in the sleeves than in the legs and torso.
  • Break Up Song: A 2D idol magazine once had a series of polls for readers' favorite songs on various topics. For "Best Heartbreak Song", three Tsukiuta songs took the top spots, and number 1 was Arata's "Sakura to tomo ni, kimi dake wo". So of course, Arata being Arata, he decides that they are now the Heartbreak Rangers, and he's the leader, Heartbreak Red. Since then, Heartbreak Red has appeared in many places around the franchise - in the stage plays, in especially in any April Fools related post, since Arata is the April representative. In summer 2018's Tsukipro Bunkasai, they even made a Heartbreak Red escape game.
  • Cast of Personifications: The groups consist of idols who each personify a month of the year, with each month being represented by both a boy and a girl.
  • Color-Coded for Your Convenience: For simplicity's sake, the motif colors of each month's representative are the same. December is gold, January is purple, February is pink, March is green, April is orange, May is light blue, June is teal, July is dark blue, August is red, September is yellow, October is dark brown, and November is silver.
  • Comic-Book Time: Averted, surprisingly. Each year the project goes on means the characters age and grow accordingly, and so do their circumstances.
  • Cover Version: The introductory CD sets have all of the idols sing covers of traditional Japanese songs.
  • Dark and Troubled Past: Procellarum has a few members that have some sad backstories. Rui, for example, had a terrible home life and went homeless, while Kai lost his childhood friend at a young age and still gets hung up over it around the time she died.
  • Dark Is Not Evil: The group with black as their unit color, and with "the Black King" Hajime, with his dark-toned solo songs, as their leader, is one of the two main groups - arguably the main group, as they come before Procella - as opposed to being the "hardcore rival" trio or quartet that competes against the sparkly, bright, rainbow-colored, intoxicatingly-plucky 7-9 member main unit, which is the pattern that many of the more popular idol series go with. In that pattern, the darker unit might become friends later on, but rarely are they the main characters.
  • Dream Intro: Hajime's first drama CD begins with him performing with Six Gravity as their leader, as he does, then reveals that the scene was a dream he had before being scouted. He wakes up remarking that the dream was very realistic, but he can't remember it.
  • Elite School Means Elite Brain: In the first drama CD, Hajime and Haru mention the high school that they go to—a private school that's said to be the top in the country, though it isn't named, for the sake of the series' "this takes place in real life" cred. The other Gravi members are amazed, and Kakeru tells Koi, "He's like the final boss, and you're Villager C!"
  • Ensemble Cast: Both groups of boy idols are the main characters in the anime, leaving 12 characters to run around with and give spotlight to. The rest of the series juggles between double that amount.
  • Everyone Meets Everyone: Six Gravity's first drama CD starts with the three pairs first meeting after being scouted. All of the partners knew each other, and went to school together, but they first meet the other pairs upon moving into the dorms.
  • Familiar: the shinjuu in Tsukino Empire. The SQ members are all bonded with Suzaku who creates separate incarnations for each of them (Chabo-kun and Reg-kun); likewise with the Alive members and Seiryuu; but the Tsukiuta members all have unique shinjuu. Hajime is bonded with Genbu, and Shun with Byakko — they can handle such powerful creatures alone because of their magic.
  • Fashionable Asymmetry:
    • Almost all of their costumes, but the boys' first season covers costumes take this to a questionable extreme. Almost all of them are wearing what looks to be opposite halves of two different jackets. It works for some of them, like Hajime's one kimono sleeve, but others...
    • In Rabbits Kingdom, Arata wears an eyepatch, because he has two different color eyes. Why? Because it's cool, that's all.
  • Fluffy Fashion Feathers:
    • Gravi's 2017 idol costumes all feature feathers. Some have them around their arms or legs, some on shoulders, etc.
    • The Lunatic Party stage play's special costumes are black with feathers, lace, and glitter, and accents of each members' image colors.
  • Four Gods: The first tier familiars in Tsukino Empire are based on these.
  • Ghostly Glide: How Diablo moves around.
  • Gold and White Are Divine: The Angels' costumes in the "Origins" Angels and Demons AU.
  • Good-Looking Privates: The Tsukino Empire AU started as an alluded to Show Within a Show that was essentially an excuse to draw them in military uniforms, because it's hot.
  • Gratuitous Foreign Language:
    • 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 voice actor's skill with the language (which is actually his first). That doesn't explain the gratuitous Henry V references in his Ani 1 solo "Happy! Phew!", though.
    • The dorm pets are called "animals" in English.
    • The Tsukiuta and 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".
  • Hair-Contrast Duo: The two leaders for both the male and female teams have this going on, with both having a white hair/black hair theme. Hajime is more parental and serious, while Shun is more laid back and likes to nap. Meanwhile, Yuki is an Ojou through and through, with Tsubaki as a free-spirit.
  • The Herald: The rabbits Kuroda and Shiroda, who found most of the members and led them to the company to become idols.
  • Homoerotic Subtext:
    • The pairs often seem more like couples than like just friends. This is especially true in their stories in the game Tsukipara, and for both middle pairs in their respective versions of the Yumemigusa stage plays.
    • Hajime and Haru's performance of their duet song "Koiwasuregusa" takes this beyond subtext.
    • On top of his relationship with Kai, Shun has a massive crush on Hajime. He goes on and on about how much he loves him, constantly interrupting important conversations to ask Hajime to pet him on the head, or call him "onii-san".
    • Rui's admiration of Iku is decidedly romantic.
    • The stage actors and voice actors have also described several of the pairs' relationships as romantic.
  • Huge Guy, Tiny Girl: The two pet rabbits, Kuroda and Shiroda. Kuroda is unusually large - when Hajime holds him, Kuroda is about the size of Hajime's entire chest. And Shiroda is unusually small, fitting in the palm of Shun's hand.
  • Idol Singer: Twenty-four of them.
  • Image Song: The series consists of more solos and duets than unit songs. Each of the boys has 4+ solos, and 2 duets, while there are only 5 unit songs (two for each group, and "Tsukinouta" with both groups). All 24 members are getting new solo songs in 2018-19, and Fluna and Seleas are getting their first unit songs.
  • Kigo: The core of the whole concept, essentially. Also, one of the many areas where this series is surprisingly full of traditional motifs.
  • Magical Girl:
    • In Procella's "Shunderella" audio drama, where they draw roles from a hat and improv a retelling of Cinderella, Rui's take on the "magician" (fairy godmother) role is along these lines.
    • The 2018 April Fools Day joke had some of the boys become magical girls for the day.
  • Magic Realism: 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.
  • Moe Anthropomorphism: Of the months of the year.
  • Lunarians: The female units. According to their backstory, they are all candidates for ruler of the moon (called Goddess Candidates), and have to undergo training and prove themselves in order to be picked. They make base up there, but easily travel from the moon to Earth. And as for why they look human— well, Humanity and the Moon People are one and the same. It's just that Humanity decided to leave the Moon at one point.
  • Ode to Food: You's special single "Hee! Hee! Foo! Foo!" is about his favourite food, curry. The B-side, "Layla, you call me splendour" uses melting curry as a metaphor for love.
  • Our Angels Are Different: The Origins AU has some of the more mythologically accurate terminology, and the multiple wings thing, but it also creates a lot of its mythology from scratch. The angels and demons are also not enemies, they get along quite well.
  • Parrot Pet Position: Bet you've never seen this with a reindeer before.
  • Red String of Fate: The "en" that binds the twelve members together is described as this. It's also, apparently, what makes them a Weirdness Magnet.
    • To use the more general metaphorical version, in Kurenai Enishi, Kakeru says that the red string of fate that binds them all together is more like a steel wire.
  • Rotating Protagonist:
    • The episodes of the anime, and the stage plays, feature different leads each time, giving each character some amount of focus.
    • The official twitter does this quite literally, with the boy for each month managing the account, and passing it to the next month's representative on the first of the month.
  • Sealed Evil in a Can: Diablo, in a box of oranges.
  • Second Year Protagonist: Sort of. When the series started, the middle pairs were this, while the senior pairs were third-years, and the junior pairs were first-years. (This is why Hajime, Haru, and Shun are seniors even though they're only a few months older than the middle pairs). The reasons cited on the trope page apply, though - the middle pairs as characters do feel like a balance between the seniors and juniors, which is likely why they're featured as mains for such compelling stories as Yumemigusa and Kurenai Enishi.
  • Side-Story Bonus Art: At various events, particularly Animate Girls' Fest, new Alternate Universe situations are created to sell merchandise. As for the story, usually just a brief outline of the worldbuilding is given. However, several of these have since become full stage plays with complex stories, and more detail to the worlds than was present in the original pamphlets.
  • Theme Naming: The boys' family names are all the poetic names of the months they represent. The girls are the same, but they take a couple of liberties with the names and what they represent.
  • Theme Twin Naming: Koi and Ai, the male and female representatives for February. They have pink hair, and their birthday is Valentine's day.
  • Tsurime Eyes: Over time, all of the boys started to slip into this to show their maturity, with only Kakeru managing to keep his large, round eyes.
  • Universal-Adaptor Cast: All the AUs that place the cast in different scenarios, from fantasy situations to turning them all into cats.
  • Winged Humanoid: The angels and demons in the Origins AU.

Tropes applying to Tsukiuta the Animation:

  • 20 Minutes into the Past: The first season takes place during the 2014 era of Tsukiuta, while the anime ran in 2016. This would have been averted for the second season, which took place in 2019 and was set to air then too, but delays had the season air one year later.
  • A Day in the Limelight: The female units get an episode to themselves in episode 8, where they all suffer a machine mishap and get Rui's help in order to change back.
  • Beach Episode: 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.
  • Eldritch Location: Shun's room. Despite being clearly attached to the Tsukipro residence building, the room seems to change, it has a suspicious aura surrounding it, and no one has seen it clearly. Goes hand in hand with Shun marketing himself as a Demon King.
  • Formula-Breaking Episode: Despite the franchise having tons of magical elements, this series is very low key with such as detailed in Slice of Life below. Episode 8 is the most explicitly fantastic in nature, however, due to focusing on the Goddess Candidates and their shenanigans.
  • Invisible to Normals: The female units turn into walking, talking Tsukiusas after a gadget went awry. Only Rui could see them and interact with them, while everyone else was confused.
  • Lie to the Beholder: When Shun and Hajime go on a date, Shun casts a spell so that they won't be recognized.
  • Ms. Exposition: We meet a fan of Six Gravity in the first episode, who carefully explains who each boy is and their relationships with each other to her uninterested little brother.
  • Product Placement: For the store Animate, in Episode 3. Haru of Six Gravity has to do a "manager for a day" event over there, while the rest of the boys take on various jobs in the facility. After the day is through, they perform a mini concert.
  • Singer Namedrop: 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.
  • The Something Song: "Tsuki no Uta" (ツキノウタ), the season 1 finale... which they topped in season 2 with "Tsuki no Uta" (月ノ詩。).
  • Stock Footage: The music videos for "Gravitic Love" and "LOLV -Lots of Love-" are used as extra performances whenever they can, or they're featured on digital screens in the story.
  • Slice of Life: While it does focus on their day to day activities as idols, it also goes into their off-time moments a lot in the show. The magical elements outside of the Goddess Candidates' episode are also severely downplayed, to the point where Shun's Demon King shtick comes off as just an act.
