So far, Jin has released 3 albums (Mekakucity Actors, Mekakucity Days & Mekakucity Records) and a single (Children Record). The final album, Mekakucity Records, was released on May 29.

All of these songs connect to each other to tell the story of a town and a select number of its inhabitants who seem to have special abilities concerning their eyes. These songs, coupled with the [[LightNovel/KagerouDaze novel]] and [[AllThereInTheManual the information that Jin releases]] come together and are collectively known as the Franchise/KagerouProject. Everything can be a little difficult to understand, so if you need any help with that there are guides to the series [[https://docs.google.com/document/d/1dnEiuBKTgjoVO0xjKmeo7QR4Cumw_qBC2Km_4FyQDwU/edit?pli=1 here]] and [[http://pkmnbreedergold.tumblr.com/post/31755847307/afterstories here]].

'''[[Characters/KagerouProject Now has a character page.]]'''

'''Please only list down tropes relating to the music here. If it refers to the [[Franchise/KagerouProject series]] as a whole or the [[LightNovel/KagerouDaze light novel and manga adaptation]], please list them down on their respective pages.'''
!!Kagerou Project contains examples of:
* ArtEvolution: It's very slight and a little hard to catch, but in the six months between Children Record and Yobanashi Deceive Shidu's art style changed from round-ish and slightly deranged stylization for each character to body builds more fitting for their ages that's more anatomically correct (though still somewhat deranged).
* AscendedFangirl: Wannyanpuu was officially recruited as a member of the project after she uploaded her exceptionally done PV for Heat Haze Daze.
* [[spoiler:BittersweetEnding: "Summer Time Record" describes the story's good ending, where all of the Mekakushi Dan members live. However, they've all lost their eye powers and memories of each other and they all drift apart, promising to reunite someday when their memories return.]]
* CallBack: As seen [[http://kikithedeceiver.tumblr.com/post/54424173544/similarities-between-kisaragi-attention-and-otsukimi here]], plenty of scenes in Otsukimi Recital are reminiscent of Kisaragi Attention. Fitting, since both are Momo's songs.
** Otsukimi Recital even begins with a short interlude from Kisaragi Attention's chorus.
* CuteMonsterGirl: Marry.
* DoesNotLikeShoes: Marry tends to walks around barefoot in "Fantasy Forest".
* DomedHometown: TheReveal of [[spoiler:the song, "Headphone Actor"]].
* DraggedIntoDrag: In [[https://youtu.be/p1fNZs9_yP4?t=1m20s 1:20 of Moon-viewing Recital]], Hibiya has it done to him for a photo with Momo, both in maid uniforms, as a FreezeFrameBonus.
* EvilGloating: ''Outer Science'' in a nutshell.
* ExpressiveHair: Mary's hair tends to start moving and waving around much like snakes whenever she feels growing excitement or happiness.
** Takane's pigtails fly upward when she'd either annoyed or flustered ([[{{Tsundere}} or both]]) by Haruka in the ''Yuukei Yesterday'' videon.
* EndOfTheWorldAsWeKnowIt: "Headphone Actor" starts out with the announcement that the world would end within the next 24 hours, and the rest of the song details the ensuing pandemonium as the main character makes a mad sprint to the city limits.
* FaceRevealingTurn: Ayano during the ''Lost Time Memory'' PV. [[spoiler:She turns toward Shintaro and opens her eyes to reveal that they are glowing red, and therefore, that she has obtained an eye power]]. It even comes during a DramaticPause in the song.
* ForcedToWatch:
** Poor, poor [[spoiler:Marry during ''Outer Science'']]...
** ''Konoha's State of the World'' is basically this trope in song form, as he's powerless to prevent the deaths of Hibiya and Hiyori during ''Kagerou Daze'', instead having to watch it over and over.
* FreezeFrameBonus: In [[https://youtu.be/p1fNZs9_yP4?t=1m20s 1:20 of Moon-viewing Recital]], Hibiya is DraggedIntoDrag for a photo with Momo, both in maid uniforms, in a split-second flash.
* GroundhogDayLoop: Implied in "Kagerou Daze", "Konoha's State of the World" and "Outer Science".
* HairDecorations: Momo tends to wear her short hair with a few ribbons and Marry also wears a ribbon after the events of "Imagination Forest".
** Seto also has a barrette in his hair.
** Ayano wears two red clips.
* {{Hikikomori}}: Marry was raised as one.
** After [[spoiler: Ayano commits suicide]], Shintaro doesn't leave his house for two years.
* IdiosyncraticEpisodeNaming: There are three variations to the song titles: Most songs in the series tend to be titled '''(Japanese word)(English word)'''[[note]]These songs are mostly akin to that of character songs as they discuss more character-specific parts of the story[[/note]], some are '''completely Japanese'''[[note]]Konoha's State of the World & Ene's Cybernetic Journey; they're in a (song's main character) no (something relevant to the song)pattern--roughly translates to something along the lines of (song's main character)'s (something relevant to the song). They tend to talk about ''plot driving'' events[[/note]], and others are '''completely English names''' [[note]]Headphone Actor, Dead and Seek & Lost Time Memory; These are extremely plot relevant songs.[[/note]]
** OddNameOut: Children Record somewhat breaks this pattern, but this is probably because it's more of an "opening song". Outer Science doesn't have an obvious reason though.
* IdolSinger: Momo from "Kisaragi Attention" is an extremely straight example. She seems to be an idol singer almost exclusively from her ability to draw people's attention with her "eye-captivating" ability, resulting in her isolation from her peers. She gains a good set of friends after meeting the Blindfold Gang members.
* ImageSong: Very prominent, as there is one for almost each of the main characters depicted.
* IronicEcho: In "Kagerou Daze", Hibiya throws himself in the way of a truck in an attempt to end the GroundhogDayLoop he was trapped in. [[spoiler: In the PV for "Outer Science", Kuroha throws Hibiya into an oncoming truck, killing him for good.]]
* MamaBear: Shion in "Fantasy Forest". [[spoiler:Sadly, she dies as a result of protecting Marry.]]
* PensieveFlashback: The PV of Shounen Brave.
* RedEyesTakeWarning: Used very prominently in "Children Record", but also seen in "Imagination Forest" and perhaps "Kisaragi Attention," though the nature of Momo's power was not particularly dangerous.
* SleepCute: Hibiya and Hiyori near the end of ''Konoha's State of the World''.
* SpellMyNameWithAnS: Is it Kagerou Days or Kagerou ''Daze''? Most have taken to the former and official merchandise lists it as the latter, but it still isn't totally clear on what everyone should use. It's the same problem with Lost Time Memory and ''Loss'' Time Memory.
* [[StandAloneEpisode Stand Alone Song]]: ''Toumei Answer'' and to some extent, ''Kagerou Daze.''
* StepfordSmiler: Ayano is a type A.
** Kano's a type A as well.
* ThisIsGonnaSuck: In Wannyanpuu's ''Kagerou Daze'' PV, just before [[spoiler:she's impaled during the second verse, you can see Hiyori frown and clutch her hands against her chest. Given TheReveal that she was also aware of the time-loop at the end of the song, she probably knew [[CruelAndUnusualDeath what horrible death she was about to experience]]]].
* ThreeAmigos: Kano, Kido, and Seto- The three original members of Mekakushi Dan.
* YearInsideHourOutside: In "Kagerou Daze", It's revealed that Hibiya had been trapped in the GroundhogDayLoop for decades.
