Hatsune Miku and her merry friends.

It started with one dot...

Hatsune Miku: Project DIVA is a series of Vocaloid-themed rhythm games released by Sega. As the title may very vaguely imply, Miku is front and center, although the other Crypton Vocaloids, Rin, Len, Luka, Meiko, and Kaito, get their share of the spotlight, as well.

The aim of the game is simple. Notes fly toward stationary targets on screen and you press their corresponding buttons when they overlap the markers. This task is spiced up by detailed, unique 3D music videos for each song, as well as quite frankly ridiculous bonus difficulties. The series finally made its overseas debut in August 2013 with Project DIVA F, with the budget re-release of the Vita version following in 2014, but the other games are relatively import-friendly. Project mirai finally made its way over with the release of mirai DX in 2015, so 3DS players can rejoice, too!

The 10th game in the main series, Project Diva X, was announced for a Vita (March 2016) and PS4 (Fall 2016) release in Japan. Also, announced a few weeks later was a version of Project Diva Arcade: Future Tone for PS4 for sometime in 2016, which will be the first Project Diva console release without a corresponding handheld version.

This series provides examples of:

  • Achievement System: Every game in the series has Titles, which are awarded for performing certain tasks and are purely cosmetic. Starting with F, the PlayStation's Trophy system was integrated, which (rather redundantly) awards Trophies for acquiring Titles. Mirai uses a Stamp Card that functions equivalently to Titles, but with Stamps.
  • Affectionate Gesture to the Head: In those entries that have the Diva Room, one of two ways to raise a Vocaloid's Affinity is by rubbing their forehead. They don't like it if you do it too long, though.
  • All the Worlds Are a Stage: X's Medley tracks, which can be thought of as a Boss Battle. Completing all the songs in the area allows you to challenge the Medley track, and the track itself is comprised of pieces from a handful of other songs mashed together, usually under the same artist.
  • All or Nothing: The Do or Die item in Mirai DX instantly kills you if you break your combo, but if you succeed, you get double the Mirai Points for it. It also omits Mercy Invincibility at the beginning of the song, but the point is moot since you have to get a Perfect anyways.
  • Arc Number: 39, pronounced "sankyu"note , like the English phrase "thank you", can also be read as "miku". As a result, this number runs rampant throughout the franchise; we'd be here all day if every example were listed, but there are some notable ones:
    • There was a limited edition DIVA 2nd Memory Stick PRO Duo that had an advertised capacity of 3.9GBnote  and sold for ‎¥3939.
    • Dreamy Theater 2nd used to cost ‎¥3900 on the PSN Store and has a specifically odd file size of 3939 MB.
    • 39, Miku's anniversary song, whenever she sings san-kyu, has the subtitles displaying "THANK YOU (39)" instead of the phonetic words.
    • Project Mirai 2 includes Puyo Puyo 39 as a minigame.
    • The 39th Stamp in Mirai DX is for having max Affection with Miku. There's also a stamp for spending 39 hours in-game.
  • Amazing Technicolor Battlefield: Holy cow, 2D Dream Fever. This song alone should come with a seizure warning installed.
  • And Now For Something Completely Different: "Kagerou Daze" in F 2nd is perhaps the only song in the series where Chance Time happens right at the start and clearing it affects the entire rest of the level.
  • Anti-Frustration Features:
    • On 2nd, Extend and F 2nd, you can unlock anything you already have on the previous game by simply transferring the save data. With F 2nd, this includes the ability to download the Extra Characters DLC.
      • A additional feature for F 2nd's save data is that it can be transferred between versions, automatically cloud saving when needed.
    • On Project Diva F 2nd, all the Diva rooms are unlocked automatically, instead of requiring you to complete a certain song on NORMAL, and most items for the mode are unlocked through progression in that mode.
    • Want to know how to unlock a particular bonus costume in F 2nd? Each song has a unlock count, plus a new Information Board, which outright explains every single unlockable you still need to get in plain terms.
    • In Arcade and Mirai, a small chunk of your Life Meter is protected by a "Safety" guard for the first 30 seconds of the song, so even if you struggle with the chart you won't immediately go from loading screen to Game Over. How much is protected, on the other hand, is determined by difficulty; Extreme/Super Hard has a considerably small "Safety" zone, while Easy has the largest.
  • April Fools' Day: 2015 had SEGA feature a video update for Arcade that had Miku performing in the giant Mikudayo head accessory. The head was subsequently made available in-game for 1500 VP.
  • Art Evolution:
    • The Dreamy Theater DLC and Arcade installments use a notably different graphic style from its handheld counterparts. The latter also uses 60 FPS, unlike other versions that are locked at 30.
    • F 2nd also remastered a variety of returning songs utilizing its new graphics and greater special effect capacity.
    • An interesting ongoing example of this trope happens with Sekiranun Graffiti, where every single version, currently up to five, Extend, Dreamy Theater Extend, Arcade, Arcade Future Tone and F 2nd, of the PV has the stage modified to display the title logo of the game it's from, meaning you can identify the song's source within less than thirty seconds of the song beginning.
  • Art Shift: A handful of songs use either an alternate style separate from that of other songs, or dedicates portions to this. For example, "World's End Umbrella" in F combines the traditional style with an anime video. "glow" in Mirai DX uses a paper cutout for Miku as opposed to a model, which also prevents her outfit from being changed.
  • Ascended Meme:
    • Hachune Miku appears in the intro and tutorial stages, as well as a shooting game in some installments, in all the Project Diva games. Tako Luka also appears in the intro for Project Diva 2nd and in several songs in Project Diva F 2nd.
    • The Tutorial song is "Ievan Polkka", which has no dancer selectable, instead the only 'dancing' is Hachune Miku waving a leek in a circular motion, referencing the Leek Spin meme.
    • Fan-created characters Yowane Haku and Akita Neru made their official debut alongside the Vocaloids in 2nd, and UTAUloid Kasane Teto was made available as DLC; all three have since shown up in regular capacity in succeeding installments, usually as Downloadable Content, although they lack songs and only exist as character swaps.
    • The original "Nyan Cat" tune made its DIVA debut in F, where it is introduced as daniwellP's "Nyanyanyanyanyanyanya".
    • Mikudayo, a mascot character created for mirai's stage program at Tokyo Game Show. It was designed with Nendoroid proportions in mind, but somehow... doesn't quite match up. Its rather uncanny appearance went memetic among the Japanese fanbase for being creepy, and SEGA has since embraced it by including Mikudayo in titles since, as well as producing official merchandise and promoting her as a mascot. She even comes in Sakura and Snow flavors!
  • All Just a Dream:
    • "Gigantic Girl"'s music video, featuring a giant-sized Miku fighting Godzilla, is all in her head.
      • Notably, in both "Gigantic Girl" and "Time Machine", where the figurines appear, Miku is building a city diorama...
    • The Chance Time video for "Kagerou Daze" features Miku waking up with a jump every time she dies, making it appear as her last failure was simply a dream. The context of the original song says otherwise, though.
  • An Interior Designer Is You: In all the games except the Arcade versions, there's the Diva Room, which lets you decorate the Vocaloids' rooms.
  • And Your Reward Is Clothes:
    • Each game has massive amounts of costumes (called "modules") to unlock. At least half the modules belong to Miku in each game. Taken to crazy levels with "Senbonzakura" in Project Diva F, which requires you to play the song multiple times to unlock all of the modules from it.
    • Some of the DLC in Project Diva F 2nd is various outfits, including three costumes for characters who are ALREADY DLC, and one who was merged into another character as of Project Diva F. Notably, one of the DLC costumes in this set is new and exclusive to Project Diva F 2nd.
      • America is rearranging the DLC packs to bring out some sets, like the four costumes mentioned above, one of which released much later, released in America at the same time.
    • Changed heavily for Project Diva X, where clothes actually give you Skills for use in Live Stage and Free Play Modes, such as Miku's "Street Pop" from F 2nd's Kagerou Daze, which grants a boost to bonus Grade Points acquired upon completing a Technical Zone. Additionally, matching a Module/Accessory's Type to that of the song going to be played also gives the player a Voltage Bonus.
  • And Your Reward Is Interior Decorating:
    • The games with the Diva Room feature also unlock furniture pieces and room themes though performance whenever you complete a stage at NORMAL or higher difficulty.
    • For some songs, usually the first song to feature a Vocaloid, you also unlock their room, so you can visit any of the Vocaloids.
      • This is removed as of F 2nd, with the main game and the Diva Room being segregated, with both room items and Diva rooms unlocking through normal use of the feature.
      • In Project Diva F and Project Diva F 2nd, Haku, Teto and Neru all use a single room that is unlocked by downloading them.
    • Diva Room was further overhauled for Project Diva X, where everything unlocks in the same way... By doing the best you can.
  • Art-Style Dissonance: Mirai DX relishes in the fact that it has the cutest style in the franchise, and then goes and pairs it with some of the most unfitting songs possible. Standout examples include "Invisible", which is straight-up 99% metal, while Aku no Musume/Aku no Meshitukai are quite possibly the darkest pair of songs in the entire franchise. If they had added any of the other songs in either seriesnote , it would have only gotten worse.
  • Assimilation Plot: The story of "This is the Happiness and Peace of Mind Committee" from F 2nd. A representative of said committee, the Siren (Miku), wants everyone in the world to be completely, unconditionally, and equally happy. Anyone who isn't... well, it won't end well.
  • Auto-Revive: The "Recovery" item in both DIVA and Mirai heals you to max health if you would have died. The former imposes no penalty, allowing you to use it to survive through difficult sections, but the latter negates your high score for using it.
  • Award Bait Song: Several songs, such as "Time Machine" and "Continuing Dream" from F and "Sakura Rain" from F 2nd. It's easier to list the songs that aren't, due to the selection being intentionally some of the greatest hits of the Vocaloids.
  • Background Music Override: Much like its appearance in another SEGA game, the Hang-On Bike from Mirai DX replaces the BGM with the Hang-On theme when used by a Vocaloid.
  • Bare Your Midriff:
    • The "Invisible" outfits for Rin and Gumi in Mirai DX. Of course, being Super-Deformed makes the whole point moot.
    • Miku's "Ambivalence" in X.
  • Beach Episode: In Project Mirai DX, you can pay 100,000 MP to travel to and stay at Mirai Resort for 7 days. The resort features an extra-large villa with many spaces for room items, including a bath item slot not available in any of the homes, and boasts many exclusive idle events such as your character sunbathing on the beach and smashing watermelons. Unlike the Penthouse, which is simply treated as yet another home but with a weekly rent, traveling to Mirai Resort takes you to a new map with every service available except Mirai Estates; you won't be able to return to your homes until your vacation time expires or you choose to forfeit your vacation time to leave early.
    • "Fire Flower" and "Summer Idol" in F, whose videos take place at a pair of beach resorts. The "Fire Flower" video includes scenes of Rin and Len (or the chosen characters if other modules are selected) playing on a beach.
  • Bilingual Bonus: In F 2nd Western release, the lyrics can now be set to translated English, while the vocals stay sung in Japanese.
    • Megurine Luka, full stop. In F 2nd, she sings Yankee Doodle Dandy, and DYE from F was sung in terrible, but understandable, English. Her unlockable wall banner even declares her as 'Bilingual Babe'.
  • Bowdlerise: Kagerou Daze. The PV alters the deaths mentioned in the song to Lighter and Softer ones (but abuses a lot of Gory Discretion Shots anyway), and in the English version, it's the only song whose lyrics do not get a full English translation, possibly due to their disturbingly graphic nature.
  • Break Up Song:
    • "Koi wa Sensou" from the first game is about a particularly bad break-up, sung from the break-uppee's perspective.
    • "Just Be Friends" from 2nd and extend is a softer example, sung from the break-upper's perspective.
    • "Kimi no Taion" in Mirai DX is a fairly sad version of this, but you wouldn't know just by watching the video.
  • The Bus Came Back: X highlights the return of many aesthetics that made the first game stand out from its successors, such as score-based clear conditions and many of the tracks being largely concert PVs.
  • Butt Monkey: Mikudayo in the "Together with Mikudayo!" promo videos for Mirai 2/DX. Pretty much all of the comedy revolves around tormenting poor Mikudayo.
  • Call Back:
    • In "Time Machine", the two toys that caused the dream from "Gigantic Girl" are sat on the floor of the treehouse, and Miku is still building her dioramas.
    • The majority of songs from F 2nd are songs that have appeared in the franchise prior to F. You can even get the other games' theme songs as DLC, as well as a "Hatsune Miku" Module from the first game that depicts a non-idol Miku.
  • The Cameo:
    • F's "Black Rock Shooter" features a quick scene where Miku flies through a fire silhouette of Insane Black Rock Shooter herself.
    • Blink and you'll miss it, but in Mirai DX's "Aku no Musume", the scene featuring Rin surrounded by a crowd of commoners also has two girls sporting Kasane Teto and Akita Neru's hairstyles hidden amongst the crowd. Yowane Haku also appears in "Aku no Meshitukai" amongst the crowd of green-haired commoners encountering the Daughter of Green. Those savvy on the Story of Evil will pick up on the fact that Haku was the Daughter of White, a "bystander" who witnessed the series' events and survived the attack on the Kingdom of Green.
    • Although Miku performs "Senbonzakura" solo in Mirai DX, outlines of the other Vocaloids in their respective costumes from F can be briefly seen in the sky in two different shots.
  • Camera Abuse: In "Rolling Girl", the camera is occasionally treated like a second character, and considering Miku is visibly pissed off for most of the video, she doesn't treat it very well.
  • Cat Girl:
    • The Kitty Cat Module. Notably, for it's appearance in F 2nd, the ears and tail are constantly twitching and moving.
    • This same trait is shared by other costumes, like Meiko's Lin Xiao-Mei costume, which have ears and tails. Previous games kept any tail parts static.
    • Miku and Meiko's "Koneko no Paya Paya" outfits in Mirai DX. It's literally half the point of the song, even.
  • Canon Immigrant: Some songs from the Mirai sub-series eventually made it to Arcade Future Tone through updates, although they lack the Super-Deformed quality of the Mirai games.
  • Celebrity Paradox: Averted In F 2nd. Among the items unlockable using the Extra AR mode are room items which include, of all things, Project Diva, Project Diva 2nd, Project Diva extend and both Project Diva f and Project Diva F, as well as a advertising stand-up Miku for the Miku Graphy Collection, and one of the Gadgets is a genuine Project Diva Arcade cabinet. Notably, Project Diva F 2nd itself cannot appear in the game.
    • Humorously parodied by one of the first modules in Project Diva. The module "Hatsune Miku" is Miku if she never even became a pop idol!
  • Classy Cane:
    • "Dream-Eating Monochrome Baku" gives the player character one, with Len being the default.
    • "Miracle Paint" in F 2nd gives the player one. Notably, every other version of the song did not have this and merely had the dancer making movements that pretended that it was there.
  • Colour-Coded for Your Convenience: The colors of the melody icons are obviously the PlayStation symbols' colors. The arrow ("W") notes are filled with colors to prevent blending with other types of icons. Hold notes have colored outlines. Star notes in the F series are yellow.
    • And of course, the difficulties are in PlayStation colors as well: Green "Easy", Blue "Normal", Pink "Hard", Red "Extreme".
    • Also used as Leaning on the Fourth Wall in F's "Acute"; harder difficulties tend to sync the notes to the signature color of the character who's singing. When Miku sings, Triangles appear, when Luka sings, Squares appear, and when Kaito sings, Xs appear.
    • Something similar is used for Mirai's "on the rocks" wherein Meiko's parts are played with A (red) and Y while Kaito's parts are played with X (blue) and B.
  • Color-Coded Characters: Each character has a particular color they're associated with. In "Aku no Musume/Meshitukai" in Mirai DX, this is also used to represent who is who.
    • Miku = Cyan
    • Rin = Yellow
    • Len = Orange (specific character color)/ Yellow (since they're "twins")
    • Luka = Pink
    • KAITO = Blue
    • MEIKO = Red/ Orange (as Sakine Meiko)
    • Haku = Purple
    • Neru = Yellow
    • Teto = Red
  • Contemplate Our Navels: The lyrics of "DYE" from , in that distinctly Engrishy way.
  • Console Cameo:
    • The music video for "Remote Controller" has a Dreamcast controller as one of the controllers. The color of the controller's logo depends on region, just like the original Dreamcast.
    • A loading screen for F 2nd features a Call Back to "Remote Controller", this time featuring the Famicom controller that appeared in the original PV as opposed to F's.
    • Handheld consoles that look suspiciously like the PS Vita appear in a few songs and some loading screens. For example, "Negiposi*Continues" uses a console that looks like a white Vita, but all of the buttons are completely wrong.
  • Cover Version: Chaos Medley ~Giga Remix~ uses a Giga-P cover of "1 2 Fanclub" with Miku and Len as opposed to the original, which used GUMI.
  • Credits Medley: The song playing during the credits sequence of F is a medley of instrumental versions of some of the game songs.
  • Creepy Doll: Present in "Ashes to Ashes" in F.
  • Crossover: 2nd received some collaboration DLC with Namco's The Idolmaster, which included Modules for Miku, Rin, and Luka based on three of the game's characters, as well as two songs from that game redone with the Vocaloids.
  • Crucified Hero Shot:
    • The player character in "Black★Rock Shooter". They get better.
    • The player character strikes this pose at the end of "Break It, Break It."
  • Cute Mute:
    • Teto outside of songs. In some games, Haku and Neru are also mute except when you clear a stage, and most of the games have no songs for them at all.
    • Averted with Gumi in her guest role in Project Mirai 2 and Project Mirai DX, where she features prominently in several songs.
  • Damn You, Muscle Memory:
    • If you played too much F 2nd on the Vita with analog sticks as Scratches, see if you can finish any Hard/Extreme songs in F without touching the stick.
      • On the flipside, Scratch notes were very forgiving, being able to be done by simply flicking the stick constantly on F - they couldn't be hit with the "safe" designation, meaning you just had to hit them in a reasonable area of their appearance to be given a "fine". F 2nd now actually requires you to properly hit the note to get a "fine/good" or "cool", making it much harder to complete Technical Zones or get a Perfect.
    • DIVA Arcade uses a button layout consisting of four buttons in a horizontal line, rather than the two sets of diamonds used by the console and handheld games. Anyone used to the latter, especially someone coming off playing on one of the limited edition arcade-style controllers, will be in for a rude awakening when they attempt Arcade.
    • Going directly from a very fast (or even average paced) song, to a slower song, such as Sakura Rain, can really throw off a player when their still trying to hit buttons at a speed that's twice the speed of the current song.
    • Mirai DX avoids this. The notes are colored to match the buttons on a New 3DS, but there is an option to have them match the PlayStation button colors. Even then, having the 'X' button be the top button instead of the bottom can still be confusing.
    • Mirai is significantly more lenient with button timing than DIVA, to the point where the kind of timing that nets a FINE in DIVA is still a COOL in Mirai, and so forth. This can be detrimental if you play DIVA right after playing Mirai, which may screw up all your timing because DIVA is much harsher when it comes to grading.
    • Mirai also doesn't require Holds, much like Arcade. Hold Notes only care about two things: hitting the note at the start, and releasing it at the end. Between then, you're free to release the button, since holding only earns some bonus points.
  • Deal with the Devil: Of a sorts in Dream-Eating Monochrome Baku. Len, a baku (read: dream-eating spirit), makes a contract with a girl to eat all of her bad dreams. After he finishes eating her bad dreams, he continues eating her dreams until the girl can't dream anymore.
  • Deliberately Monochrome:
    • In "Kagerou Daze", any version of the song beyond Normal only uses Circle and X, even on Extreme difficulty. This is a reference to the original PV, which only ever used the colors red and blue; everything else was Deliberately Monochrome.
    • A similar thing happens with "Aku no Musume" and "Aku no Meshitukai", where the characters are rendered as just black figures with the hair and clothes of the character, except for the singer themselves.
  • The Dev Team Thinks of Everything:
    • There are several songs in F series where, even though a character may not appear as a selectable module, s/he will still appear in the song. If you select a Vocaloid other than the default, the default character will replace the selected one within the song. The default character will be wearing the appropriate outfit for the song too, if the character they replace had a special outfit (like with "Senbonzakura"). Taken to another level in "Rin-chan Now!", where the selected character's name and color appears correctly on their Twitter-like feed, even Haku, Teto and Neru, as well as Sakine Meiko.
    • In "God-Tier Tune," if you select a Kaito or Meiko module, they'll still have a super-deformed model to replace Miku's, despite not appearing in the song otherwise.
    • Several modules in Project Diva F, like Linkage and FOnewearl, have glow-in-the-dark light up panels built in. If the character wearing the Module winds up in a dark environment, the panels will glow.
    • The Factory Tyrant module has moving gears on the wrists and ankles, as well as a spinning disc on the chest. Even in shots where the scene is otherwise static, they never stop moving.
    • One of the Extra Markers available in F requires a Promo Rare Weiss Schwarz card known as "Nice to Meet You! Hatsune Miku", which depicted Miku backed by AR marker icons. Although the set was released in English, that card in particular never made it overseas. Those curious can alternatively grab a replica off the game's official website.
    • The Vita version of F 2nd has the same button timing test option as the PS3 version. This option is completely useless for a Vita user, but, if you own a Playstation TV...
    • A new element in the new PV for Intense Voice Of Hatsune Miku, as a Chance Time Bonus, is that the notes for the following rapid note sequence have holographic markers added.
    • The new Language option on Project Diva F 2nd allows all but one song to have full English lyrics. These new subtitles also carry over to the Diva Room, where the game even subtitles the questions and comments they say to you during normal use.
      • Due in part to the new translation effort, and fan demand, the lyrics bar for the English release has a limit of just over 40 characters.
    • When you pass the Extra mode AR marker scan over an image of the box art of any of the first five games on F 2nd, the game scans it, and creates a Bland-Name Product version of all five games as items you can put in the room.
      • Several pieces of publicity artwork for Hatsune Miku also are detected and give you those items in the game. There's no reason to keep them in the game for the english release, but all of them photograph and are translated where possible.
    • Some people bought Project Diva F 2nd on import, which normally would mean lots of lost progress on trophies and songs. The trophy list is all regions, and all you need to do to recover a japanese save is to upload it to the cloud, then import it to your US or EU copy!
    • If you try to equip a head or face customization item on a module that normally wears a hat or mask, the hat or mask will disappear so the customization item doesn't clip through it, even if you can't normally get a hatless or maskless alt version of that module.
    • Mirai DX comes with the option to switch the note colors between those used by Nintendo consoles and those used by Playstation consoles, for people who prefer the latter, and more common, colors. Also handy for avoiding confusing the placement of buttons on a 3DS with the placement on a PlayStation controller.
  • Difficulty By Region: Downplayed; the first Technical Zone in F 2nd's "Cantarella ~grace edition~" is ten notes longer in localized versions for no apparent reason. It's possible this is simply a mistake.
  • Difficulty Spike: Puyo Puyo! 39 in Mirai DX can be quite easily cheesed for the first couple stages; creating a Chain higher than three is usually not needed. Then you hit MEIKO, who will send your run down the toilet if you aren't actually good at the game.
  • Disproportionate Retribution: The Daughter of Evil in Mirai DX finds out that the Prince of Blue likes the Daughter of Green more than he likes her. So what does she do? She destroys an entire kingdom. Overnight.
  • Double Unlock: Most of the games use a currency system, which allows you to buy items for your Divas, but you must first unlock them by completing a particular Guide Dang It task. Retired in X, which shifts to completing Quests and Chance Time in Live Quest Mode to unlock Modules and Accessories.
  • Downer Ending: The regular ending of the "Hello*Planet" subgame in 2nd, if you fail to acquire the Orb and take it to the secret exit in Level 4. This results in the normal ending as seen in the original song, where Miku is reunited with the boy in heaven, but has passed away.
  • Downloadable Content:
    • New songs, new modules, et cetera. extend had most of 2nd's DLC included.
    • From 2nd onwards, Yowane Haku, Akita Neru and Kasane Teto are available as bonus characters, with one or all of them included in the DLC packs available each game, if not the game itself.
    • With Project Diva F on PS3, around a dozen extra songs added as post-release DLC with the Vita version are included with the DLC modules being assigned to the songs they represent, including Senbonzakura having a total of SEVEN costumes, which are unlocked by completing the song a total of TEN times on any difficulty.
    • Two of the most iconic songs of Project Diva F, "ODDS & ENDS" and "Tell Your World" were added as Live Mode songs for Project Diva F 2nd.
      • Which was trumped for Miku's Anniversary DLC, as the Project Diva Extend opening song, Sekiranun Graffiti was brought back, with future DLC plans including Look This Way, Baby from Project Diva 2nd
      • Also, SEGA announced, Day 1, you can buy every piece of DLC outright, at a discount, including the DLC they're still releasing.
    • All of the DLC skins for Project Diva F 2nd are available free... for 39 days from their release.
  • Dualvertisement:
    • The music video for "The MMORPG Addict's Anthem" takes place at the Shop Area Stage in Phantasy Star Online 2. If you succeed at Chance Time, Miku is depicted acquiring a Rare Item, which the PV displays as the Rappy Wedding Cake Room Item. Afterwards, this item is made available in the shop for purchase. Notably, this is one of the few items that can still be unlocked even if the song is completed on Easy.
    • While the song "Black★Rock Shooter" was an original song that inspired the anime of the same name, the version used in F is the one from the anime as opposed to the original, and the PV used features set pieces inspired by the anime.
    • The Song "Tell Your World" was originally created for Google to advertise how Hatsune Miku has become a worldwide phenomeon. In the first Project Diva game to come to the West, the song is included. Say it with me. A song made to advertise Miku's popularity worldwide, where she sings of how she wants to sing to everyone, is included in Miku's first worldwide game release, and also appears as Live Mode DLC for the second, with a translation that makes it impossible not to feel you're part of something special...
  • Dub Name Change: A handful of song names in F got... weird translations. "Left Behind City" became "Urbandonment", and "Netgame Addicts Sprechchor" (which was already its official English title according to the Japanese version, no less) became "The MMORPG Addict's Anthem", to name a couple.
    • With F 2nd, this was essential, due to the song "Genga Spoofing". The easy translation would be "Gengar Spoofing", but, obviously, with this being a SEGA game on a Sony console... They translated it as "Doubleganger"...
    • Averted with Mirai DX, where several titles are left completely untranslated. The end result is that some titles can be a mouthful for an English speaker not learned in Japanese pronunciation, such as Arifureta Sekai Seifuku (Common World Domination) or Gaikotsu Gakudan to Riria (Skeleton Orchestra and Lilia).
      • Also averted with the Puyo Puyo! 39 minigame, rather surprisingly. In any localization of Puyo Puyo that wasn't a Dolled-Up Installment, the franchise was always called Puyo Pop prior to Mirai DX.
  • Duet Bonding: "World's End Dancehall" from has Miku and Luka facing off in a heated dance battle, only for them to hit it off at the end when they realise the crowd loves it.
  • Early-Bird Cameo: Miku uses a Fei-Yen costume in Project Diva extend. Several years later, Fei-Yen turns into a familiar idol...
  • Early Installment Weirdness:
    • Those used to later games may be put off by the first game's lack of Extreme mode, hold and arrow notes, and songs that aren't performed by Miku. Some music videos are also just slideshows, and the pass/fail system is entirely dependent on your score, both things that were gone by Project Diva 2nd.
    • Games before F did not contain star notes, Technical Zones, Chance Time bonus scenes, customization items... or rock paper scissors.
    • Even worse with Project Diva Arcade, which has points where you need to hit two notes at once and a slide note.
      • Or, in the case of some songs, three or FOUR notes at once...
      • And the same note charts are coming to PS4 with the announcement of Project Diva Future Tone, with confirmation that the double and triple note patterns will not be changed.
    • Project Diva F 2nd adds two new types of star note, one of which requires you to scratch two-fingered, the other requiring you to complete a combo, often slightly out of tune with the song itself.
      • The new star note mechanic also ties into Chance Time, where you can actually CANCEL the bonus animation by doing the final star note with both fingers or analogue sticks.
    • Project Diva X adds the rush note, where you have to mash the corresponding button as much as you can before the note expires.
  • Earn Your Fun: To unlock a song's Hard chart, you have to clear its Normal chart first. To unlock the Extreme chart, you need to clear the Hard chart first.
  • Earn Your Happy Ending: The secret ending of the "Hello*Planet" DLC subgame in 2nd. If you pick up Water, you can use it to feed the potted plant in your inventory as opposed to healing yourself. If you keep doing this until the counter above the plant reaches 50, it will dispense an orb. This allows you to access the secret exit located behind the regular one in Level 4. This takes you to a secret Level 5, and if you complete it alive, Miku makes it to the boy's grave intact, but trips, falls flat on her face and drops the potted plant, causing the pot to shatter. This causes an angel to appear, who summons the boy's corpse to Miku. Miku, with the power of the orb and seven rainbow melodies, then begins to sing the chorus of "Hello*Planet", which causes the dead boy to come back to life. The credits then shows the two regrowing the Earth's plants together.
  • Easter Egg: In the Mirai series, Miku can obtain an Arle Nadja outfit. If you then start up Puyo Puyo! 39 while Miku is wearing it and start a Chain, all of Miku's normal voice clips will be replaced with clips of Miku shouting Arle's spell names as in the Puyo Puyo series.
  • Easy-Mode Mockery: Playing on the Easy difficulty in F and F 2nd prevents you from unlocking the Hard versions of songs, and some modules and items. Additionally, if you choose to use a help item, the rank shown will have a green heart beside it. Some help items go further and automatically give you the CHEAP/LOUSY/SO CLOSE rating regardless of performance, preventing you from unlocking new songs.
    • One of the cheapest, in gaming terms, help items was removed for F 2nd, which allowed you to, on any difficulty, play it with only the basic note types of Easy Mode.
  • Engrish: As the Vocaloid 3 modules were only finished a few weeks before the release of Project Diva F in English, all the songs but one are only translated in that Romanji is used on the karaoke bar. Also, All the Vocaloids, when, as of recent updates, all of them have a english voice bank, still use the original engrish victory announcements. Several fans of Project Diva have took it upon themselves to remix, using the Vocaloid 3 English voicebank, several of the songs from Project Diva F and have so far shown almost half the songs sound just as good, if not better, in english!
    • This is slightly averted by the song 'DYE', in that the song is sung in very poor Engrish throughout, so didn't need translating.
    • The lack of english is averted, in a very cute fashion, in F 2nd... Luka uses the english Yankee Doodle chant for the new minigame, in all regions, purely since she's always spoken passable english!
      • Then averted even more in a shocking move, as SEGA announced that the subtitles now have an option on all but ONE song to translate faithfully the lyrics into full English, approved by Crypton and the original composers, for the western release!
  • Everything Trying to Kill You: Kagerou Daze. Speeding truck? Discarded liquor bottle? Steel pipes from said truck? Car crash? Slippery staircase? Conveniently broken bridge railing that falls apart when someone leans on it? Averted in the lyrics, where the only improbable death is being impaled by a falling steel pipe, quite viciously.
  • Fake Longevity:
    • To unlock a song's Hard chart, you have to play its Normal chart first. To unlock its Extreme chart, you have to play its Hard chart. This quickly becomes a hassle if you've played other games in the series and can get PERFECTs on Extreme charts, because you're forced to play through charts you are far more than capable of clearing just to get to the challenging charts.
    • Unlocking 100% of the Modules in the original PSP game requires clearing all of the songs sung by Miku (32 of the 36) and getting either 5 Normals or 1 Great... per character! This also has to be done six times, using a character's original module for each run, making it almost a waste to use any of Miku's other costumes.
    • Project Diva F 2nd restores this aspect somewhat with the Information Board challenges, which include cumulative score or note totals. Notably, some of the challenges are to get NO notes of one of the types. Most of them aren't any worse than having to clear a song 5 times or play it once on each difficulty, but a few in particular require double-digit clears while "I'll Miku-Miku You (For Real)!" has one that requires a minimum of 20(!) clears.
  • Fanservice: Every game is obligated to have one song that features the lead girls in swimsuits, such as "Summer Idol" from F. Doesn't stop it from being one of the hardest songs, though.
    • As mentioned in Shout-Out further down, the games are filled with references to SEGA's original properties, with each game having at least one costume based on a SEGA franchise.
  • Fission Mailed: Obtaining the Chance Time bonus in "Sadistic.Music Factory" leads to the bad ending that involves failing to escape from the factory.
    • Several Item Events have "Fail" versions where the character messes up what s/he is doing in some fashion.
  • Follow the Leader:
    • 2013 saw the release of Megpoid the Music#, a similar rhythm game for the PSP featuring the popular Vocaloid GUMI.
    • Gumi also appears in selected songs in Project mirai, however she has not been licensed for Project Diva itself.
    • And in 2014, IA/VT Colorful does the same for IA on the Vita, courtesy of Marvelous AQL.
    • Miracle Girls Festival is essentially Project DIVA, but as a Massive Multiplayer Crossover with several anime franchises. Especially notable in that Miracle Girls is also made by SEGA, runs on the exact same engine as DIVA, and features very similar gameplay.
  • Four Element Ensemble: X introduces five Elements and the Element Areas that together make up the world that the Vocaloids live in, those being Neutral, Cool, Cute, Beauty, and Chaos. In gameplay, each of the Element Areas is inhabited by songs of that Element, and using Modules and Accessories with matching Elements give you a boost to Voltage Rate.
  • Freeze-Frame Bonus: The potted plant from "Hello Planet" can be briefly seen in exactly two shots near the beginning of "Negaposi*Continues".
  • Funny Background Event: During the video for "LOL -lots of laugh-" in Mirai 2, Miku is riding a teacup ride. Briefly in the background, the rabbit leading her through the candy-filled amusement park is flailing around madly in her own teacup.
  • Funbag Airbag: Happens to Rin in one of the gallery images in F 2nd as she dives for a beach ball and ends up with her head on Miku's chest.
  • Gameplay Grading: Being a rhythm game series, this is obviously present, though with worded grades rather than letter grades. From worst to best, they are MISS×TAKE (DROP×OUT in F's English release), CHEAP (LOUSY in F's English release or SO CLOSE in F 2nd's English release), STANDARD, GREAT, EXCELLENT, and PERFECT.
    • Project Mirai forgoes the words and simply uses Rank Inflation, ranging from D to SS/S+.
  • Getting Crap Past the Radar: Really, it's amazing what kinds of songs can sneak past the radar.
    • In Project Diva F 2nd, we have songs which include very intimate Les Yay, several different ways to kill someone, sex, (possible) suicide, Blackjack, more sex, prostitution, borderline drug-induced rape, and a recipe for a cocktail, almost all of which are fully translated into English.
    • Mirai DX, while overall more lightheared than the main series, also has fun themes like sex ("Romeo and Cinderella"), aforementioned cocktail ("Clover Club"), beheading ("Aku no Musume" and "Aku no Meshitsukai"), flat-out genocide, homicide, and incest rape, none of which (quite conveniently) is translated. Note that this game has a lower rating than that of the main series.
  • Global Currency Exception: Unlike DIVA, which uses the same currency across all in-game purchases, Mirai DX uses the 3DS' Play Coins for purchasing Help/Challenge Items. While it's entirely possible to play the game without ever spending on items, three of the possible items also boost overall Mirai Point acquisition, which can make it tempting to spend on them.
  • Goggles Do Nothing: GUMI's "Invisible" has her wear goggles on her head, but she doesn't actually wear them.
  • Gory Discretion Shot: In "Aku No Musume" and "Aku No Meshitsukai", when the evil princess Rin (actually Len in disguise) is executed, there is a cut to a black screen with a falling ribbon as the guillotine falls.
  • Gotta Catch 'Em All: Arcade has tons of special trading cards you can collect by completing challenges, which can then be used with an online Mini-Game.
  • Grass Is Greener: "Negaposi*Continues". Turns out living in a video game isn't all it's cracked up to be.
  • "Groundhog Day" Loop: Miku gets stuck in one in the "Chance Time" version of Kagerou Daze.
  • Guide Dang It: Averted in F 2nd. A new feature adds a Information Board which tells you what unlockables you can unlock in a song, in a easy to read format. Of course, so it's not TOO easy, it only reveals them in stages.
    • Also played straight in the same game's Diva Room unlocks as there are several unique items unlocked outside of the songs that are only obtained through certain numbers of various events such as visiting it daily, accepting requests and even making up with each Vocaloid after making them angry with no real way to track progress.
    • In Mirai, non-song-related outfits fall straight into this category.
      • Miku's Snow Miku series of outfits. You need to place the corresponding Nendoroid in a Mirai Room.
      • Getting a particular Vocaloid's Pajamas. You need to raise a Vocaloid's Friendship to a high enough level, as well as put them to sleep for at least a certain number of hours at least once.
      • The bonus faces. Hatchune Miku requires getting all of the Miku outfits, Super KAITO requires getting all of the KAITO outfits, and Mikudayo requires getting all the outfits.
  • Hammerspace: In the "Hello*Planet" game, Miku can apparently hold a ton of stuff that goes apparently nowhere, including a whole hot air balloon.
  • Harder Than Hard: Extreme difficulty, home to some of the toughest charts in the series, like Negaposi*Continues, Sadistic Music Factory, and The Intense Voice of Hatsune Miku.
    • Arcade takes it up a notch with Extra Extreme, a bonus difficulty that includes reworked charts with Slide Notes for older songs that didn't previously have Slide Notes.
    • Mirai DX introduces Super Hard difficulty, its equivalent of Extreme in the DIVA series. However, only six songs have the option, and the player must both beat the game and achieve an S Rank or higher on that song's Hard chart to unlock it.
  • Hazardous Water: In Hello*Planet, Miku's life drains when she's in rain, although she prevents it by picking up an umbrella partway through. In the corresponding game, rain does indeed hurt you, as well as small pits of water. After picking up the Umbrella, you can stop rain damage by equipping it, but while holding it, you can only walk. However, it also causes you to descend a half speed after a jump.
  • Healing Potion: In the "Hello*Planet" game, Miku can pick up bottles of clean water. Using one restores a whole heart to your life gauge. However, you can also expend them to water the potted plant, which is key to earning the Golden Ending.
  • Hope Sprouts Eternal: Kami Kyoku/God-Tier Tune revolves around chibi Vocaloids tending to the last plant on Earth in order to awaken Goddess Miku.
    • Hello Planet. Miku is tending to the last viable plant on Earth. In either ending, her faith is rewarded at the eleventh hour.
  • Hotter and Sexier: F and F 2nd bring us much more fanservice-geared songs such as "Hm? Ah, Yes.", "Nostalogic", "Blackjack", and "Envy Catwalk".
    • An intentional example in extend as "Colorful X Melody" featuring Miku and Rin appears midway down the list, then a reprise with Luka and Meiko titled "Colorful X Sexy" appears near the end.
  • Intercourse with You: A lot of the songs. To name a few, there's "magnet", "Romeo & Cinderella", "Hm? Ah, Yes.", "Iroha Uta"...
  • Interface Spoiler: Did you buy a physical copy of Project Mirai DX? Don't look at the song AR cards unless you want most of the songlist spoiled for you.
  • Jiggle Physics:
    • Meiko and Luka got it going on in . Even the modestly-endowed Miku gets in on the action, depending on the outfit.
    • The game even uses some jiggle physics on the hair of Miku, Luka, Haku and Neru, so their ponytails bob about almost realistically.
    • Averted with Mikudayo, who moves like someone wearing a heavy mascot costume would.
  • Jump Scare: Early in the video for "LOL -Lots Of Laughs-", a bunny mascot's face abruptly fills the screen with no prior warning. If you weren't expecting it and are the kind that gets spooked easily, expect it to throw off your rhythm.
  • Leaning on the Fourth Wall:
    • In the intro for Project Diva F, the DX7 synthesizer is uncovered, gathering dust, that appeared in the PSP intros, and Miku is depicted as moving on, reflecting the fact F and F 2nd are PS3 and Vita games, instead of the original system of a PSP game alongside a Dreamy Theatre upscaling program.
    • Expanding from this is that the first three games are portrayed as being set at a exclusive academy, while Project Diva F and F 2nd are set after they have graduated, with the iconic synthesizer absent completely from F 2nd.
      • In Sakura Rain in Project Diva F 2nd, Miku is shown walking around this academy, with several locations seen in the various intros shown prominently.
      • To take it a notch further, the song itself is about saying goodbye after graduation, and that hopefully they'll return to meet again someday.
    • One of the Gadget items for Project Diva F is the plainly named Project Diva Arcade Machine, which is a genuine arcade cabinet for Project Diva Arcade, which can be used to play the credits game constantly. Annoyingly, The Gadget list misnames it as 'Game Console' when selected in the Diva Room.
    • The words and music for The Disappearance Of Hatsune Miku and Tell Your World are incredibly meta, the first having her sing about how she's terrified of the end of the song, and the latter having Miku singing about the fact she's on the stage right now singing for the world.
      • Intense Voice Of Hatsune Miku also has very meta lyrics, in that she outright declares that the song itself is a 'answer' song to Disappearance, which talked of the end of her shelf life, declaring that she has no shelf life, as long as Vocaloid exists. Ever since its english localization, Every revision of Vocaloid has a version of Miku. Yes, Miku, You Are Alive.
    • The music video for Sadistic Music Factory is about someone having escaped a tyrannical factory owner. As the song continues, it's revealed that the person she's looking for is the player themselves!
    • One of the new aids given for Intense Voice Of Hatsune Miku is that, from halfway through the song, the music video itself, if you complete Chance Time, changes to allow you to more clearly see the arrangement of the notes, purely since the notes might have changed, but the speed most definitely hasn't...
  • Licensed Game:
    • In two ways. It's themed around the Crypton-produced Vocaloids (this unfortunately means no Gakupo, for instance) and a few fan derivatives, and technically, every single song is a licensed song, since they're preexisting songs made by producers who are not SEGA or even Crypton staff. The fact it uses so many licenses made the localization of Project Diva F a shock, especially since almost none of the songs are cut, only removing a special download-only version of PoPiPo, presumably since SEGA couldn't renegotiate the rights to use Toro and Kuro.
      • A surprising licensing issue cropped up with Sakura Rain, in that it was unable to be licensed for inclusion in ANY games after the original Project Diva up until it appeared again, finally, in Project Diva F 2nd.
    • The inclusion of Akita Neru, Yowane Haku and Kasane Teto, as well as modules specifically for them, Sakine Meiko, Tako Luka and Hachune Miku is purely since piapro licensed every single one of them under the Crypton Future Media banner. Ever since, they have appeared, legally, complete with songs specific to them, in the Project Diva games. This licensing does not extend to use of Kasane Teto's voice, which is created using UTAU, which piapro cannot license, meaning she has no songs or bonus modules on any Project Diva game, and was not added to Project Diva Arcade until much later.
      • This was averted in F 2nd when she got a new Sweet Camouflage Jacket module, her first extra module EVER, and was given Swimwear, finally, alongside the other Divas, who have had some since Project Diva 2nd...
    • Gumi has only been licensed as a exclusive cameo character for Mirai 2 and Mirai DX, and only appears in duets. She has not yet been licensed for any Project Diva game, including Future Tone.
    • Project Diva F 2nd uses, for Japan only, piapro's own music archiving website to archive the music for Edit Mode, allowing gamers to optionally attach the song file to a PV, removing one of the bugbears of Edit Mode, namely that you can't always find the song. Due to there being no equivalent service in the West, even from Piapro themselves, the feature was axed.
    • Another licensing problem came with F and F 2nd coming out in English at all, since they needed to get approval to do the english lyrics. When Project Diva F was successful beyond all expectations, Crypton approved SEGA meeting with the composers to create the licensed translations the fans wanted.
      • However, Mirai DX still uses the original translation style.
  • Life Meter: Like in many other rhythm games. However, you also need to finish the song with enough Grade Points (or, in earlier games, at least a certain percentage of COOL or GOOD judgements) to clear the song properly.
  • Little Bit Beastly:
    • Several versions of this are available in F and F 2nd including rabbit, dog, fox and cat parts, with F 2nd adding parts for a nekomata and nine-tailed fox.
    • The costumes for "Animal Fortune-Telling" in Project Mirai 2 and Deluxe, as well as "Amatsu Kitsune". "Animal Fortune-Telling" has Miku as a Koala, Luka as a sheep, Rin as a tiger, and Meiko as a Tanuki. "Amatsu Kitsune" has Rin as a fox.
  • Logo Joke: The logo screen has Miku singing "Se-gaaaa!", similar to how older Sega games had the "Se-gaaaa!" yell. Later games had Rin, Len, Luka, Kaito and Meiko join in randomly.
  • Love Triangle: "Acute" from F has one between Kaito, Miku, and Luka. As if to drive the point home, the stage is even shaped like a triangle! It doesn't end well, either.
  • Luck-Based Mission:
    • The room items in the original game are unlocked by random chance after clearing a song. Many of them require a Great but even then aren't a 100% guarantee. This was averted in F and F 2nd, where they are unlocked by simply completing the songs on NORMAL or higher.
    • Getting a lot of the Mirai Room stamps more or less borders on random chance, as in, the Vocaloid actually has to use the object in question, which is completely decided by the AI. Some stamps take it a step further and require a certain result from using a specific item, which is even more luck-based than getting your Vocaloid to use it in the first place. Then there are the idle events...
    • Provided you aren't great at Puyo Puyo, playing against Kaito in Project Mirai basically amounts to hoping that he doesn't get a three or four chain.
  • Lyrical Dissonance: The standard Chance Time footage for Kagerou Daze depicts a goofy video of a very strangely dressed Miku trying to get to her concert without dying somewhere along the way, where all deaths are Played for Laughs. The song itself tells the tragic tale of a boy stuck in a "Groundhog Day" Loop for decades on end while hopelessly trying to save a girl who repeatedly dies in increasingly gruesome ways.
    • Notably, The lyrics vanish completely when you're playing the song in English, due to the gruesome nature.
  • Male Gaze:
    • Present in Meiko's song "Nostalogic" in Project Diva F. The camera often locks on or swing pasts her midriff, rear, or chest.
    • Made even more hilarious if you get the Chance Time for Nostalogic, which causes the camera to become glued to the player character's chest.
    • Luka's "Blackjack" in F 2nd brings this back in full force. Many songs (such as "The World Is Mine") focus on a female Vocaloid's butt every now and again.
    • Songs in Project Mirai DX focus on the female characters' rears again...except they're all Super-Deformed and don't have anything to show off as a result.
  • The Many Deaths of You: Kagerou Daze's "Chance Time" video has Miku dying in numerous different ways, including being hit by a car, crushed by steel pipes, falling down a staircase, being in a car crash, or getting crushed by stage props.
  • Marathon Level: Mirai only uses full versions of songs, unlike the main series, which cuts some songs for time. This mostly sounds like a positive, until you get to tracks like "reverse rainbow" in Mirai DX, which clocks in at just over five minutes, in a franchise where hitting four minutes runtime is already considered quite long.
    • Project Diva X introduces the Medleys, six medleys of songs by various composers, which are much longer than normal, as the final concerts in each area. Of course, the final medley to complete the game is a medley of the absolutely evil songs by cosMo.
  • Market-Based Title: Mirai Deluxe is Mirai DX outside of Japan. Despite this, all versions of the game have Miku saying "Mirai Deluxe!" when you highlight the game's icon on the 3DS's Home Menu.
  • Meaningful Name: The mirai in Project mirai is a reference to the Alternate Character Reading of "未来", which can also be pronounced "miku".
  • Mercy Invincibility: In Project DIVA Arcade and the Project Mirai series, you're granted a brief period of "safety" at the beginning of the song; your Life Meter is restrained from falling below a certain amount until the safety wears off.
  • Mini-Game:
    • F has Rock Paper Scissors. There's also Mini-Game Credits that you can repeatedly access upon purchasing a Project DIVA Arcade machine. F 2nd brought back Rock Paper Scissors, and added a Patty Cake minigame.
    • Mirai DX has Puyo Puyo! 39, which is Puyo Puyo with Vocaloid characters and background music. You can also play Mikuversi with your Vocaloid partner, even if their name isn't Miku.
  • Money for Nothing: Play the game often enough, and you'll have way more Diva Points/Mirai Points than you'll know what to do with. Somewhat subverted with the latter as well, since if you decide to move into a Penthouse, you'll have to keep feeding the Vocaloid a hefty 30,000 Mirai Points per real-time week to keep staying. Also heavily averted with Arcade, which dispenses Vocaloid Points at such a paltry rate that you'll have to grind for VP at least once every day if you intend on buying all the available outfits.
  • Motor Mouth: To varying degrees based on the song, from short spurts in "Secret Police" to constant and nigh-indecipherable in "Rin-chan Now!", "Sadistic Music Factory" and "Two-Sided Lovers". Most blatant in the infamous "Intense Voice Of Hatsune Miku" from 2nd, which not only features high-speed singing in long bursts, but also makes you tap buttons at the same speed. It was later reintroduced in F 2nd, but the difficulty was greatly reduced with a new note chart that features far fewer notes than before.
  • Mini-Game Credits: In F's closing credits, you play as Hachune Miku, throwing leeks at the credits to score points. Amusingly, after you complete the game on NORMAL, you can buy an item that lets you play it whenever you want, and new features are unlocked as you play the credits game multiple times.
  • Mythology Gag:
    • In F 2nd's version of The World Is Mine, if you score the "Chance Time" event, you get a bonus scene of a posing Miku mimicking the cover art design of the "The World Is Mine" album single.
    • The video for magnet has a segment that mimicks the album cover. F 2nd's version adds butterflies for the final segment as its Chance Time bonus event.
  • Nerf: Between 2nd and F 2nd, "The Intense Voice of Hatsune Miku" (Hatsune Miku no Gekishou) received a severe nerf in the sense that the abnormally long high-speed chains at the end of 2nd's version were replaced with a series of much shorter chains punctuated by a few spaced-out notes. The song is still difficult, but not nearly as much. It's probably because of this that in F 2nd it became the second-to-last song instead of the final, of which F 2nd's is definitely no slouch.
    • Notably, Intense Voice has it's last played notes on EXTREME be a 18-note Technical Zone which goes by at the same speed as the original Extend version's chains... and this one isn't one single type of note.
    • And the Arcade version's last notes are a chain which literally has you needing to dance your hands over ALL FOUR NOTES, with seemingly three notes at once needing to be played. Two hands, three notes. Surprisingly, Some players HAVE managed it.
  • Never Say "Die": At the end of "This is the Happiness and Peace of Mind Committee" in the English version, the last word has been partially censored in a form of a Leet: "[)34[)". Same way as in the Japanese version where the kanji of that word is replaced by a circle.
    • Also, Kagerou Daze is the only song in the game whose English lyrics aren't included, due to describing several of the deaths in graphic detail.
    • Averted with The Happiness Of Peace And Mind Committee, where Miku cheerfully lists all the ways she'll kill you if you're not happy.
  • Nintendo Hard: Although the games have a fairly simple learning curve, the game gets to be this whenever you have to press different buttons in succession. Additionally, while many games simply have a stage clear requirement of "have this many points" or "keep your Life Meter from hitting zero", in this series both of them are in effect, so you can make it to the end of the song but still fail it.
  • No Fair Cheating:
    • A lot of the stronger Help Items limit your maximum rank for a song. For example, in F, Star Killer and Double Killer, which lets Scratch Notes be performed with regular buttons and removes W Notes respectively, prevent you from earning higher than a Standard. Simple Rhythm, which changes all inputs to be Onote , and Training Wheels, which turns all BAD and LOUSY into SAFE, prevents the song from being counted as complete.
    • In the Project mirai side series, Recoverynote  prevents your score from being counted, as does Role Modelnote . Averted with Auto-Spinnote  and Specialnote , which only increase MP rewards but not score, as well as Do Or Dienote  which is the opposite of an assist item anyway.
  • Nostalgia Level:
    • Project DIVA F 2nd brings back updated versions of past songs, such as "Packaged" from the first game, "Romeo & Cinderella" and "Intense Voice Of Hatsune Miku" from the second, and "A Thousand Years' Solo" from extend...
    • This extends to the modules in the same game, with confirmation of the Nyanko and Heart Hunter modules from the PSP games, the latter being well known due to it's use with videos of the first game's rendition of "Two-Sided Lovers", which returns with the PV and module it used in extend.
  • Oddball in the Series: DIVA Arcade takes a few liberties from its handheld and console counterparts:
    • Your success or failure is determined completely by score, like the first Project DIVA game. The game helps with this by showing you a visual guide of how many points you have compared to how many points you should have at that point to get a minimum clear.
    • The buttons are arranged in a line, rather than a diamond like the signature PlayStation diamond. Anyone not accustomed to this button setup is advised to play on lower difficulties first to adapt to it.
    • The safety mode at the beginning of each stage.
    • The game runs at 60 frames per second instead of 30. Not even Project DIVA F on PlayStation 3 runs at more than 30 FPS.note 
      • Not that it didn't stop a arcade-perfect PS4 version coming out in 2016.
    • The game utilizes a graphical style more in line with Dreamy Theater than the actual DIVA series.
    • Holds are no longer mandatory. Holding a hold note down simply gives you bonus points, up to 3000 per hold note if another note of the same button doesn't appear early enough to interrupt the hold.
    • "Chord" notes now use different buttons. On harder difficulties, chords of 3 and 4 buttons are not uncommon.
    • Normal mode actually uses all four buttons.
    • There are no Technical Zones or Chance Times. This factors in to how you succeed at Chance Time mentioned below.
      • This is the only change for Project Diva Future Tone, where Chance Time is restored.
    • The newer revisions of the game have a version of the star note from F, the Slide Note, indicated by a bar across the top of the control area that you slide one direction or another to complete the note.
    • Netting the "Chance Time" ending of a song only requires you to hit the notes highlighted in rainbow; anything before that is completely irrelevant to whether you get it or not.
  • Off with His Head!: The Daughter of Evil's or rather, her servant who looks identical to her ultimate fate in Mirai DX's "Aku no Musume" after a coup overthrows her as ruler. Naturally, the game uses a Gory Discretion Shot.
  • Oh Crap!: Miku has this reaction when being invited into a haunted house in "LOL -Lots of Laughs-" in Mirai DX.
  • Old Save Bonus:
    • Having the original game's save on your memory stick will net you all of its costumes for free, plus an exclusive DIVA Room poster and title, in the sequel. Likewise, having a 2nd save will get you all of its costumes and such for extend.
    • Due to the console jump, F doesn't allow this. Its sequel, F 2nd, does however, in that possessing save data from F unlocks those Modules in F 2nd.
  • Original Generation: Some songs are created specifically to appear in this series. Highlight examples include most of the theme songs, "Nega*Posi Continues" and "Ageage Again".
  • Pacifist Run: Enforced in the "Hello*Planet" game. Miku's only "weapon" is a bubble blower that shoots giant bubbles. The bubbles cannot actually kill enemies, but traps them for a few seconds, allowing you to walk past them unharmed.
  • Painting the Medium: If you succeed at Chance Time in the F 2nd version of Intense Voice, the video will flash boxes and circles across the screen corresponding to the location of notes moments before they appear, allowing the player to anticipate the notes.
  • Parental Bonus: The lyrics for Clover Club include a recipe for the cocktail the song is named after, done in such a way that only someone aware of what Miku is saying would be able to mix one up.
  • Proper Tights with a Skirt:
    • Rin's Trad School module in F and Miku's Noble module in F 2nd.
    • Miku also uses tights with the FOnewearl costume just like the default FOnewearl from Phantasy Star Online 2, when the normal default version omits them.
    • Rin's "Astray" from X.
  • Randomly Drops: The revised Module acquisition system in X turns unlocking new Modules into this for Live Quest Mode, where succeeding at Chance Time may additionally grant you a random Module, accompanied by a Transformation Sequence and a big honking on-screen display shouting "MODULE GET!". Certain Skills can increase the odds of a Module appearing, such as Miku's "School" Module, which comes with Rare Module UP Lv.1, a skill that slightly increases the odds of acquiring a rare Module.
  • Rearrange the Song: Almost all of the songs in the "Hello Planet" subgame either sample the song of the same name or are this.
  • Relationship Values: Every iteration of DIVA Room features these, with a separate gauge for each character. You can raise these with Item Events, giving them gifts, or simply interacting with them. However, in Project Diva F and F 2nd, the Derivative Vocaloids do not have the gauges, due to the DLC only unlocking their module and limited voice data.
    • In F 2nd, all the new features of Diva Room do not work with the Derivatives, due to the new mechanics also being removed along with the relationship meter.
  • Retraux: True to sasakure.UK's Signature Style, "Hello Planet" and "Negaposi*Continues" use chiptune as BGM.
  • Rhythm Game: Yes.
  • Sarashi: Rin wears this over her chest in her "Ame" outfit.
  • Scoring Points:
    • Pre-X games have primarily two systems:
      • The first scoring system is the traditional points system. You get points for hitting notes on time, and you also get bonus points for hitting notes during Chance Time and holding down notes.
      • The other is the Grade Point system, which is simply an overall percentage of your note accuracy, with a few bonuses for completing Technical Sections and Chance Time.
    • X omits both systems used prior in the series and replaces it with Voltage, which functions identically to points in both Hatsune Miku: Project DIVA and Arcade, where completion is determined by score. In Area Quest, Voltage is also used for restoring the current Area's Gem, and many Quests require getting a certain amount of Voltage on a song to clear them.
    • The Project Mirai spinoff games features "SP" segments: Occasionally, you'll encounter yellow lines and if you combo every note including the glowing note at the end, you'll get 2500 points. Like X, there's no Chance Time or Technical sections. Compared to other games in the series, holding down hold notes gives very few points.
  • Self-Imposed Challenge:
    • Some of the rhythm game items you can choose will make the song harder in various ways, ranging from making targets appear much later and preventing recovery of your life meter.
    • Songs in F 2nd can make it even harder with multiple challenge items in one go! That's right! Can you ace "Intense Voice" on Extreme with icons that appear later than normal, flowing in random directions at high speed?
    • On another note, getting a Perfect. There's absolutely no gameplay benefit to it - no awards are given other than trophies in the Vita and PS3 games - but landing one is much harder than it sounds as long as the "safe" designation exists...
  • Sequel Difficulty Spike:
    • The final PSP entry, extend, may very well be the hardest game in the series. Songs on Extreme are now filled with high-speed rapid chains.
    • F 2nd's Normal mode is much, much more difficult than the previous game, bearing more resemblance to that game's Hard mode. Strangely enough, the other difficulties are about the same.
    • Project Diva Arcade: Future Tone added, for it's first revision, Extra Extreme, a bonus option available for select songs that introduces the Slide Note to preexisting charts.
    • Averted with Intense Voice Of Hatsune Miku, where the most recent version is the easiest.
  • Sharp-Dressed Man: Len's default outfit for "Monochrome Dream Eater" in F, complete with a matching Nice Hat.
  • She Is All Grown Up: Rin's Future Style module.
  • Shout-Out:
    • "Remote Controller"'s BGA features a Sega Dreamcast controller, which replaces the Famicom controllers in the original PV because you can probably guess how Sony would feel about Nintendo copyrights in games on their systems.
    • "Nyanyanyanyanyanyanya!" has a scene where the lead singer is picked up by a handsome cat with a personal cruise liner. The lead singer is then shown standing on the bow of the ship with arms outstretched, mimicking the iconic scene from Titanic.
    • Hm? Ah Yes... is a fractured version of Cinderella, complete with the 'clock striking at midnight' and 'glass slipper' motif, except Miku destroys the entire ballroom, instruments, clock and all.
    • This loading screen from F 2nd has the Famicom controller from the "Remote Controller"'s original PV plastered in the dead center of the image. The controller wound up getting recolored with PlayStation colors, but it retains its Famicom controller shape.
    • Initally, the Project Diva intros featured a Yamaha DX7 synthesizer somewhere in them, including Project Diva F revealing Miku's one has the voice settings for 37-39 read 'Best Friends Forever'. This same synthesizer is one of several instruments that are built into Miku's outfit. Unfortunately, in Project Diva F 2nd, The DX7 is not present.
    • Being licensed by SEGA, every game is obligated to have at least one Module from a SEGA game.
    • Due to it being used in one of the songs, you can use the Stage portion of the ARKS Shop Area in F's Edit Mode.
    • The bonus level for the Mini-Game Credits in F is called the Fantasy Zone Stage.
    • In Project Diva ARCADE, and Project Diva Future Tone for PS4, There are versions of Magical Sound Shower, FINAL TAKE OFFnote , and the theme song for Quartet remixed with full vocals.
    • How does Miku defeat Godzilla in "Gigantic Girl?" With Chun-Li's lightning kick!
    • The description for the roadroller item in Mirai DX was just about pulled straight out of Jojo's Bizarre Adventure.
    • The PV for Watashi no Jikan makes good on a couple of old memes, mainly Nice Boat and Leek Spin.
    • Several Room goods in Mirai DX are ripped directly out of SEGA franchises, including a statue of Sonic the Hedgehog, an Opa Opa, and a working Hang-On Bike that your Vocaloids can play with.
  • Sibling Rivalry: "Remote Control" in F just screams this for Rin and Len, though they most-often get along very well in their other duet songs.
  • Silly Love Songs: Several. "Melt" and "Ai Kotoba", for example.
  • Sir Not-Appearing-in-This-Trailer: GUMI doesn't appear in any of the openings for the Mirai subseries, even though she has top billing in several songs.
  • Sleep Cute:
    • The end of the anime video of "World's End Umbrella".
    • Invoked by the Alarm Clock room item, in that the Vocaloid themselves goes to sleep so that, when the alarm goes off, they wake up with you.
  • Spotlight-Stealing Squad: Despite "1 2 Fanclub" being named a Rin song in Mirai DX, Rin herself is the backup while Gumi does most of the singing.
  • Stalker with a Crush: Miku and Luka big-time for Rin in "Rin-chan Now!"
  • Stripperiffic: Some modules are borderline, but the clearest example is definitely Meiko's Blue Crystal: Her breasts are covered only by a belt!
  • Stock Shout-Out: In the '393 Quest' diva room theme, the message box above the bed will periodically display, "Thank you Miku! But our diva is in another castle!"
    • Notably, with the '393 Quest F' version, the line is changed to read 'Stage' instead of 'Castle', and is the only English string on any version of the theme, the rest of the text being untranslated.
  • Stylistic Suck: Miku's animation in Mirai DX's "Hello Planet" is very choppy to emulate a retro game sprite animation until the end, when she reunites with the boy in heaven, tying into the whole "retro video game" aesthetic of the video and the song itself.
  • Super-Deformed:
    • God-Tier Tune in F uses chibi models for Rin, Len, Luka, and the lead singer.
    • The Mirai subseries uses Nendoroids as a basis for its style. The original game's appearance at Tokyo Game Show also lead to the appearance of Mikudayo, which was supposed to be this... save for the fact that she was disproportionately chubby and lacked a neck, causing the whole outfit to come off as chillingly creepy. After it went memetic in the Japanese fanbase, it later became an Ascended Meme, appearing in every subsequent DIVA game starting from F as a customization option.
  • Surprisingly Good English: Luka's rap in "Ai Dee". Notably, this is one of the few songs where her English is perfectly understandable to a native English speaker.
  • That Russian Squat Dance: Miku and Meiko briefly during "Koneko no Paya Paya" in Mirai DX.
  • Three Minutes of Writhing: Some of the music videos are this. To name some examples, there's "magnet" and "Change me" from 2nd,"Hm? Ah, Yes." and "Nostalogic" from , and "Brain Revolution Girl" from X.
  • To the Tune Of: "Cendrillon" and "Adolescence" in Mirai use the exact same song, the difference being that the former is performed by Miku and KAITO, the latter by Rin and Len. They also have different lyrics. This is referenced in the PVs themselves, which use an identical dance routine save for the opening, which reflects the theme of the song. They even use the same splitting note track, but a different path is taken depending on the song.
  • Token Mini-Moe: Rin and Len, of course.
  • Too Long; Didn't Dub: The lyrics in F were subject to this due to requiring licences. Averted in F 2nd, which acquired the necessary licences to translate almost every song except "Kagerou Daze". Mirai DX also does this with its lyrics, which notably affects plot-heavy songs like "Aku no Musume/Meshitukai", which make far more sense if you know what the song's actually saying.
  • Transformation Sequence: Acquiring a Module in X is depicted by a scene cut from the video into a view of the five Element Gems merging into the player Vocaloid, transforming them into the Module you just acquired.
  • Translation Correction: Some slight instances of Engrish were corrected for the English release of F. For example, "Rest X Notes" seen during a Technical Zone became "Notes Left: X".
    • For F 2nd, further translations were done, with the vague 'WORST/AWFUL' note designation now being called 'MISS', and the 'LOUSY' rating being replaced by the more optimistic 'SO CLOSE'.
    • Subverted in Mirai DX, where "MISS" notes are suddenly "WORST" again, and "COOL?" notes (hitting a note with the wrong button) become "MISS" notes.
  • Trash the Set: Tengaku from F has the stage where Rin is playing burst into flames and begin to collapse as part of the Chance Time event, to the point where she's standing in flaming ruins.
  • Twin Switch: How the Servant saves the Daughter of Evil in "Aku no Meshitukai"; he switched places with her at the last second so he would be killed in her place.
  • Unflinching Walk: Luka does this briefly in "DYE" in Diva F as columns of ice shatter around her.
  • Updated Re-release:
    • 2nd# fixes several bugs and niggles, speeds up load times, and comes with a free DLC code that gives you all of extend's costumes to use. extend could be considered this to 2nd, especially seeing as how it's working title was Project DIVA 2.5.
    • In a more traditional example, F is a re-release of .
    • Project Diva Future Tone is an updated rerelease of Project Diva Arcade, restoring common Project Diva features and transferring it to the PS4.
    • Literally, some songs are redone using newer voice banks to make them sound more natural, like the 1st generation song "Koi Suru VOC@LOID", which sounds very different in X due to the song being reproduced in the Hatsune Miku V3 engine.
  • Variable Mix: Missing a note in some of the games will cause whatever vocals corresponding to that point in the music to not play. Miss notes repeatedly and the characters will sound like they forgot the lyrics. Some games, like Extend and the Mirai subseries, do not have this. Additionally, you can turn it off in games it appears in.
  • Wave Motion Gun: The train in Mirai DX's "Senbonzakura" has one, used for exorcism, for some reason.
  • When She Smiles: The opening movies for the games are some of the few instances where Hachune Miku actually smiles.
  • Wholesome Crossdresser: Len's Phoenix Moon module, a feminine kimono, and Rin's Ame module, a masculine happi coat, in F, their default outfits for "Kagamine HachiHachi Flower Fight".
  • Who Wears Short Shorts??: Miku's Yellow module in 2nd, extend and F 2nd, Rin and Len's sport-themed modules in F.
  • Word Salad Lyrics: "PoPiPo"'s English verse is absolutely full of this.
    Let's take, you are lovin' it!
    Vegetable juice
    You must love this drink, I've decided now!
    So take now, with true heart, vegetable juice
    It costs just two dollars!
  • Zettai Ryouiki: Miku and Luka in their default outfits. Most of the other characters also get in on this with their optional modules. Even Len!
