Franchise / D4DJ

Go To

"D4 FES", a DJ festival that is the stuff of legends. Inspired by this festival, Japan too experiences a new dawn in DJ culture. As DJs become the main method for people to experience music, performers called "DJ Units" have begun to appear. As a culture that can be enjoyed by anyone, young or old, DJing has become an indispensable music genre. And now, 6 new DJ Units set their sights on this floor. Happy Around!, Peaky P-key, Photon Maiden, Merm4id, RONDO, Lyrical Lily. The story of these girls aiming for the greatest moment begins!

D4DJ (full title: Dig Delight Direct Drive DJ) is a media mix project created by Bushiroad. Following in the steps of projects like Shoujo Kageki Revue Starlight and BanG Dream!, D4DJ is a multimedia franchise centered around DJing. D4DJ currently consists of three major works: D4DJ Groovy Mix, a Rhythm Game for iOS and Android, D4DJ First Mix, an anime series, and D4DJ Petit Mix, a Super-Deformed Web Original series. There are also several manga adaptations. Furthermore, the franchise has several original songs, some with their own live shows or MVs.

The franchise currently focuses around nine units, split into two groups:

  • Side:Origin, which consists of the original six units:
    • Happy Around!: The protagonist group of the series. A bubbly idol-themed unit who aims to bring a smile to everyone. They are the newest DJ unit of Yoba Academy. Their primary music genre style is a combination of J-pop and dubstep. They also use happy hardcore and gabba.

    • Peaky P-key: A popular Hollywood-themed DJ unit in Yoba Academy. Also known as Peaky, their music style is a combination of techno, hip hop, and rave music.
    • Photon Maiden: A futuristic-themed unit working under an entertainment agency, whose members have been selected through a nationwide audition. They captivate the audience with their choreographed performances and electro pop songs. Their music style is a combination of trance, techno, and dance music.
    • Merm4id: A glamorous summer-themed DJ unit with a mellow and sexy vibe formed by second-year college students. Bringing "good vibes" through their performances, they aim to become famous like Photon Maiden. While their music style is similar to the group in question, it is primarily a combination of trance and rave music.
    • RONDO: A goth rock-themed DJ unit consisting of second-year college students who work at a famous local club. Centering around their vocalist, they specialize in heavy rock songs, with guitar played live. Their music style is mainly a combination of trance and rock with touch of drum and bass.

    • Lyrical Lily: An angelic-themed high school DJ unit from the prestigious Arisugawa Private Academy. Their music style is a combination of trance, house, and classical music.
  • Side:Nova, which consists of the three units added since launch:
    • Call of Artemis: A formerly legendary DJ unit. Splits into subunits called Lynx Eyesnote  and Scarlet Canarynote 
    • Abyssmare: A foreign unit who has suddenly appeared in Japan.
    • UniChØrd: A space-themed unit formed by Michiru Kaibara.

D4DJ First Mix follows the three high school units who attend Yoba Academy, while D4DJ Groovy Mix follows all six groups in an original story where the units take part in a DJ festival called D4Fes. The English version of the game was officially released May 27, 2021.

A second season of the anime, entitled D4DJ All Mix with all six of the groups, was announced in April of 2022 and will air in January 2023.

This franchise contains examples of:note 

  • 2D Visuals, 3D Effects: First Mix uses CG models for any character that needs to dance or wears the same school uniform as the main cast, while the unique but non-dancing characters—such as the café owner, Maho's siblings, and Happy Around! as kids—are traditional 2D animation. The environments also swap between dimensions, depending on whether there's going to be dancing in it.
  • Aborted Arc:
    • At the end of the first episode of First Mix, Maho is astonished to discover Rinku is some kind of DJ wunderkind, able to subconsciously mix tracks like a pro. Since Rinku immediately shifts to lead vocalist/dancer and leaves all the actual DJing to Maho, this has no bearing whatsoever on the rest of the series.
    • Rinku originally had a Stage Name as "Link"note  during her duo stint with Maho. From the third episode, however, Rinku drops this and uses her actual namenote  for the group with no apparent reason.
  • Advertised Extra: First Mix focuses on the three groups who attend Yoba Academy: Happy Around!, Peaky P-key, and Photon Maiden. The other three units have cameos, but aren't relevant to the plot at all.
  • Amazonian Beauty: Jennifer of Peaky P-key is ripped, to the point she constantly posts pictures of her abs on social media. Instead of updates, she calls them "ab-dates". She also does air chair squats at the lunch table.
  • Animal-Eared Headband: Muni wears a bunny ear headband.
  • Animation Bump: Rinku's cafeteria scene in episode 7. It's twenty glorious seconds of Looney Tunes nonsense as she wolfs down three plates of food and almost chokes to death.
  • Anime Accent Absence: All four members of the American unit Abyssmare speak in fluent Japanese without any American accents whatsoever. While this could be chalked up to Translation Convention during scenes where they are talking amongst themselves, they don't seem to have any issues communicating with Japanese folks despite having recently flown in from the U.S. as of their introduction arc in Groovy Mix, and their songs have primarily Japanese lyrics with Gratuitous English at best. Even more strangely, Photon Maiden has songs with more frequent and more fluently-written and -sung English lines, and all four of its members are Japanese (like with all of the other units).
  • Battle Rapping: Episode 12 of First Mix revolves around a rap battle that Rinku and Muni use to work out their feelings about their childhood friendship falling apart.
  • Bifauxnen: Aoi's androgynous good looks bring many female fans to the club just to see her.
  • Bland-Name Product:
  • Champions on the Inside: After struggling to make it onto the Sunset Stage, Happy Around! bomb out in the first round. Still, they're just happy that they got to compete alongside Peaky P-key at all.
  • Cool Big Sis: Hiiro acts this way to the rest of RONDO.
  • Darker and Edgier: Compared to the other six units, RONDO's music is more melancholy in tone, and their motifs and costumes make extensive uses of blue, violet, and black.
  • Did Not Do the Bloody Research: In episode 13 of First Mix, Rinku flashes the "peace" sign at the audience. She then turns it around and accidentally gives them the two-fingered salute, a very rude gesture in the United Kingdom.
  • Early-Bird Cameo: As Rei walks home in episode 4 of First Mix, she crosses paths with RONDO playing shiritori.
  • Exergaming: Muni has a copy of Ring Fit Adventure, but she doesn't seem to use it. Rinku comes over specifically to train with it, and rocketed all the way up to level 50 while Muni's profile was still on level 3.
  • Expressive Accessory: In episode 3, when Muni strikes a horrified face at Maho's flier, Nyochio copies her expression.
  • Fun with Acronyms: Dance For Dangerous Jack, a first-person shooter that Muni plays. Its initials are, of course, D4DJ.
  • Gamer Girl: Muni can often be found playing anything from Ring Fit Adventure to hardcore military shooters.
  • Girl in the Tower: Invoked by Kyoko in episode 7 of First Mix, who constantly saw Shinobu sitting at the window in her room like an imprisoned princess.
  • Hidden in Plain Sight: The assistant at the café Happy Around! frequent just so happens to be the woman who co-performed "WOW WAR TONIGHT", which inspired them greatly as children. They don't notice, and the series doesn't draw any attention to her at all, instead passing her off as a minor character.
  • Hypocritical Humor: In episode 4 of First Mix, when the soon-to-be Happy Around! are waiting for the results of the contest, Muni chides the others for being too nervous while her hand is shaking so bad she spills her tea cup everywhere. When Maho calls her out, Muni yells it's just tendonitis, because "art gods get tendonitis!"
  • Japanese Ranguage:
    • Rinku's name comes from "to link", since she's the one who brings Happy Around! together.
    • In episode 12 of First Mix, Rei says that rapping is all about "rhymes", to which Rinku responds with "Like the fruit?" Since "lime" and "rhyme" are only homophones in Japanese, that pun doesn't make sense in English.
  • Magical Security Camera: In episode 9 of First Mix, after attending Photon Maiden's concert, Happy Around! watch a video of the performance back. It's identical to the actual concert, with snap zooms, whip pans, and soaring crane shots right over the crowd's heads. While that sort of stuff is feasible at an outdoor concert with drone cameras and dedicated camera crews, this takes place in a cramped high school practice room.
  • Meaningful Echo: In episode 3 of First Mix, Maho is forced to fill for time at their planned concert while Rinku chases down the vanished Muni. When they reappear, Maho plays it cool and says, "A DJ's gotta bridge gaps sometimes, you know?" Later, in episode 12, Maho hatches a plan to reunite Rinku and Muni after they have a falling-out. When it works, and they bridge the emotional gulf between them, Maho plays it cool and says, "A DJ's gotta bridge gaps sometimes, you know?"
  • Mood-Swinger: From the final episode of First Mix:
    Maho: "Peaky P-key just praised us!"
    Maho: "You're the last person I want to hear that from!"
  • No Hugging, No Kissing: averted. The Groovy Mix 2nd Anniversary update introduces an official couple to the franchise.
  • Older Than They Look: Nagisa has a petite build and is the same height as Michiru (a middle school student), but according to “4-koma mix”, she’s actually 20-21.
  • One-Gender School: Due to the nature of the (pseudo-)idol genre, there's not a lot of boys to be found. Yoba Academy, the school Happy Around!, Peaky P-key, and Photon Maiden attend, has zero male students, and Lyrical Lily comes from an elite all-girls academy.
  • Overly-Long Gag:
    • In episode 4 of First Mix, Maho finally asks Muni what the thing on her head is. Muni simply states, "Nyochio," as if that explains everything. What follows is seventeen seconds of Stunned Silence and Squeaky Eyes as Maho waits for clarification from Muni, who's said all she needs to say.
    • In episode 6 of First Mix, the girls head to Rei's house for a study session but quickly get wrapped up in making dinner. As Maho relaxes in the hot tub, she thinks to herself, "Why did we come here again?" It's followed by a static shot of Maho smiling pleasantly at the ceiling for sixteen whole seconds, before the shoe finally drops.
  • Overly-Long Name: "DJ Mash & Rinku with VJ Only + Togetsu Rei". They quickly decide to dub themselves Happy Around! instead.
  • Plot-Mandated Friendship Failure: The penultimate episode of First Mix involves Rinku and Muni falling out over how their childhood friendship withered away.
  • Product Placement: The DJ controllers featured in the series are actual products made by Pioneer DJ.
  • Self-Plagiarism: "Electric Chaos Countdown" is just Noriyasu Agematsu recycling "Gyakko no Flugel" from Symphogear.
  • Suspiciously Apropos Music: When eavesdropping on Happy Around!, the café owner always tries to read the room and play something appropriate from his vinyl record collection. Such as Frédéric Chopin's "Funeral March" after they lose a contest.
  • Those Two Guys: The café owner and his assistant, who eavesdrop on the girls whenever they use the cafe for a strategy meeting. The owner always searches through his vinyl records for some Suspiciously Apropos Music, only for his assistant to chide him about interfering.
  • Tomboy and Girly Girl: Maho is significantly more tomboyish than the other members of Happy Around!: she has Boyish Short Hair (though after the game’s first anniversary it’s grown slightly longer), wears shorts instead of a frilly dress onstage, and has an interest in sports and is depicted playing basketball in one of her cards. Meanwhile, Rinku is a sweet, bubbly Genki Girl, Muni is a Kawaiiko with a Sweet Tooth and a penchant for wearing pink frilly dresses, and Rei is a polite, graceful Elegant Classical Musician.
