Music / Diaura

Diaura (ディオーラ Dioura), stylized as either DIAURA or Di-aura, is a four-member Visual Kei band from Tokyo which blends sounds of metalcore, alternative metal, heavy metal and hard rock. Formed at the end of 2010 by ex-Valluna vocalist yo-ka, guitarist Kei and drummer Yuu, who were later joined by bassist Shoya, the band quickly developed a cult following due to their vaguely militaristic concept (the name of the band is short for Dictatorial Aura) and dark aesthetics that appealed to both old-school Visual Kei aficionados and younger fans desperate for an alternative to the then-inescapable wave of garishly-colored, pop-oriented oshare bands. Despite this, they have also received a lot of backlash from former Valluna fans who berated them for not being enough like Valluna and even bullied their newer fans.

In May 2012, just two months following the release of their first album, "GENESIS", Yuu left due to tendinitis and was replaced by Tatsuya, drummer of session band Ronove and long-time friend of Shoya's. Tatsuya remained a support drummer for about a year before becoming an official member shortly before the release of the single SIRIUS/Lily.

Formed under the now-defunct record label Galaxy Inc., Diaura later moved to Ains, then recorded FOCUS with blowgrow (a quasi-major label also home to the bands Angelo and Penicilin) and is now signed to Ains.


  • yo-ka: lead vocalist, lyricist and arguably the most well-known member of the band. He can also play guitar and drums when needed, has composed several of the band's songs, as well as three demos. Used to be part of the bands Icy., Marely and Valluna, and has also been a Megamasso roadie for a while.
  • 佳衣 (Kei): guitarist, backing vocalist, co-founder and main composer, he is currently the band's eldest member. He used to be part of bands ADOLF, CRIMSON, Bunny Drug and Valluna.
  • 翔也 (Shoya): the bassist and yo-ka's Chew Toy of choice. He has played guitar in several bands before he joined Dizly as a bassist. Upon leaving Dizly, he was planning to join a completely different band, which is why he had to be asked three times before he agreed to become Diaura's support bassist. Has been good friends with Tatsuya since 2009.
  • 達也 (Tatsuya): replacing Yuu as the drummer, he has composed the song "The Redemption" and is currently the youngest member of the band. He was formerly part of short-lived bands Dis Marionette and Ronove.
  • 勇 (Yuu): drummer and co-founder alongside yo-ka and Kei, he left Diaura after just one due to tendinitis and was replaced by Tatsuya as the band's official drummer just one year later. He started out in Marely alongside yo-ka (under the stage name "Aya") and followed him in Valluna. However, he left after a short while due to musical differences and was replaced by Kanade.

Please Call My Tropes:

  • Adorkable: Shoya.
  • Added Alliterative Appeal: Sakura Sacrement.
    • Shitsuyoku no Seiiki.
    • Todokanu Tegami.
  • Aerith and Bob: The members' names are Kei, Shoya, Tatsuya and yo-ka.
  • Adult Fear: The lyrics of Rakuin-stigma- seem to imply either raping or murdering one's significant other (or both) in a fit of jealousy. Ouch.
  • All Just a Dream: The ending of the song Lily.
  • all lowercase letters: yo-ka. Also, their songs anti people, a genesis of the end, evil, black sheep under the shallow sleep and their song (and single) blind message.
  • Ascended Extra: Tatsuya was a support member for almost one year before becoming the band's official drummer.
  • Ascended Fanboy: The label "blowgrow" is owned by Kirito, ex-vocalist of Pierrot and current vocalist of Angelo, yo-ka's main inspiration.
    • Diaura have also participated to Angelo's annual "Intersection of Dogma" concert.
  • The Atoner: Todokanu Tegami and Rakuin-stigma- both revolve around this trope, but the most blatant one by far is The Redemption.
  • Badass Boast: In an interview for the release of to ENEMY:
    yo-ka: We will step forward as far as we are able to until all of Visual Kei is under our dictatorship.
  • Berserk Button: So far, yo-ka has: being rude to his fans, comparing Diaura to Valluna and calling him a country boy.
  • Blonde, Brunette, Redhead: A male example. At one point, yo-ka was the blond, Yuu was the brunet and Kei was the redhead.
  • Body Horror: Kindan Ryouiki provides us with this tidbit:
    Glaring more, open your eyes/ They're grotesque, as if they're melting.
  • Breakup Song: Infinite is probably the most notable example.
  • Breakout Character: Tatsuya. He started out as a mere Replacement Goldfish for Yuu, but now he is just as loved and respected by the Diaura fandom as Yuu.
  • Broken Record: "Red die, red die, red die, truth die", from Akai Kyozou, and "Ware no tame ni shininansai" ("Die for me!"), from DARK AGE.
  • Can't Hold His Liquor: yo-ka stated that he has a low alcohol tolerance.
  • Catch Phrase: yo-ka's "Who's your master?".
  • Cluster F-Bomb: Judgement and anti people both contain this.
  • Censored for Comedy: In Virgin Mary, half of the word "eien" (="forever") is censored. There is no readily apparent reason for this.
  • The Chew Toy: As a fan very nicely put it, yo-ka loves nothing more than to physically put Shoya in his place.
  • Color-Coded for Your Convenience: yo-ka has said that he thinks of the band's songs in terms of "black" and "white".
  • Cover Version: So far, the band has covered ROUAGE's Endless Loop (the Legend of Basara opening), Miku Hatsune's Lost Story, SADS' Nightmare and hide's Beauty&Stupid. yo-ka has covered angela's Shangri-La and Rei Kugimiya's Orange (the Soukyuu no Fafner opening and Toradora! ending respectively) alongside guitarist of Megamasso, and he has also done vocal covers of Gotcharocka's 秒速愛 (Byosoku Ai) and D's 花惑 as part of a vocal covers album in which Jui (of Gotcharocka) and Asagi (of D) have also done covers for Diaura's Akai Kyozo and Shitsuyoku no Seiiki.
  • Deliberately Monochrome: The PVs for Lily and Gekkou.
  • Department of Redundancy Department: SIRIUS provides us with this masterful line:
    "Fixed-point observation - normal; no abnormality detected".
  • Dystopia: A theme of many of their songs. The trope name is even invoked in the very first line of Code 0 ("Orderly incorporated dystopia under surveillance").
  • Distaff Counterpart: Asked how his mother is like, yo-ka said she's just like him, except female. Fans have joked about how she must be Medusa.
  • Expy: Despite his similarities to Kirito, yo-ka is not one. However, he has one - Ryo, vocalist of the indie band Mediena.
  • Five-Man Band: If we count Yuu:
  • Foreshadowing: "Do you remember it, the name of that star?", from Garden of Eden, is a Call Forward to SIRIUS.
  • Gratuitous English: Many songs contain this, with results ranging between Surprisingly Good English and outright Word Salad Lyrics.
  • Gratuitous German: Despite the band's concept, this is only used once, in Shinsekai.
  • Hair-Trigger Temper: So much the case with yo-ka.
  • Hell-Bent for Leather: yo-ka in the PV for SIRIUS and the second PV for Shitsuyoku no Seiiki.
  • Heterosexual Life-Partners: yo-ka and Yuu have been friends for longer than anyone in the band, and Diaura is their third band together.
    • Having been close friends since 2009, Shoya and Tatsuya also qualify.
    • yo-ka and Kei have known eachother ever since 2008, when yo-ka joined Valluna.
  • Hidden Track: DOGMA on "SIRIUS/Lily"
  • Japanese Pronouns: yo-ka uses "boku" and even "watashi" in his songs, but he uses the very masculine "ore" everywhere else.
  • Leaning on the Fourth Wall: Garden of Eden and SIRIUS both read like love songs, but are in fact about the band itself.
  • Long Title: Lost Rain~ushinai no ame, sono kioku to no kyousei.
  • Lyrical Cold Open: Diaura are huge fans of this. So far we have Akai Kyozo, Aria, Enigma, Futatsu no Kizuato, Horizon, Juusankai wa Zetsubou, Kinshiroku, Shinsekai, Sleeping Beauty, Todokanu Tegami and Zangetsu no Tomoshibi.
  • Lyrical Dissonance: Toge. The instrumentals set the mood for an upbeat, Horizon-esque song, while the lyrics talk about escaping from abuse, most probably by killing oneself (the latter of which is mostly evidenced by the lines "Goodbye, world!" and "Look! I fall upside-down./ I saw it so many times,/ Carved within your eyes.../ This ending.").
  • Madness Mantra: "Red die, red die, red die, truth die" (from Akai Kyozou). "Ware no tame ni shininasai" ("Die for me!") from DARK AGE being quoted right after the line "Your usless brain's going psychotic", qualifies as a literal madness mantra.
  • Mood Whiplash: The band makes an outright hobby out of pairing soft or upbeat songs with rough and dark songs, which results in most if not all of their releases coming across as this. In fact, the only notable aversion is the single Silent Majority.
    • As yo-ka would put it:
    yo-ka: If I were to describe Lily using a color, it'd be "white". So, if we put it on the A-side on its own, something seems to go wrong. As a result, it became a two-song A-side, together with SIRIUS. [...] You can't constantly sing about darkness. The white element is also very important to Diaura.
    • The entirety of Judgement. It starts out by saying After repeatedly crossing over despair, we'll meet each-other in this place/ Let's sing the song of joy until the sun comes out/ Let's hold hands and step out, walking towards a brand new era/ We aimed towards the place where the sun shines... continuing to believe the same thoughts as on that day. Pretty nice so far, right? Well, the song then goes on to say Tell those who claim to have high demeanor but show their mental deficiency instead:/ "Look, look, this is the reality, the truth!"
  • Metal Scream: yo-ka just loves to indulge in this.
  • Mohs Scale of Rock and Metal Hardness: Their music is mostly 3-7, but can go all the way to a solid 9 in songs like Juusankai wa Zetsubou, Inferiority Complex or Kindan Ryouiki.
  • Mr. Fanservice: yo-ka. For proof, just fast forward to 5:10 and play from there.
  • Neoclassical Punk Zydeco Rockabilly: The Other Wiki describes Diaura as a blend of metalcore, heavy metal and hard rock, but they have thrown just about anything into the mix, including but not limited to soft rock, pop, punk, electronica, Arabian traditional music and cat noises. No, really.
    • It should come as no surprise that most of this mixing and matching went into the creation of FOCUS. It's as if the album's whole point is not to have a particular point.
  • New Sound Album: FOCUS and everything after it.
    • As yo-ka said in the Visulog interview for RUIN:
    yo-ka: We've always been a band about tearing things down and building them up again.
  • Non-Appearing Title: It'd be easier to count the songs that avert this.
  • No Pronunciation Guide: You wouldn't be able to tell what Kei's name is by looking at it, because the kanji read something along the lines of "Kae" (pronounced "Ka-eh").
  • Not Christian Rock: The choruses of Jikai and Aria reference Jesus ("Jesus Christ,/ Give me hope,/ Jesus Christ,/ If you are real" and "Jesus tell me reason for my life" respectively), and Shitsuyoku no Seiiki is an entire song about lost paradise, but whether or not yo-ka is Christian is up in the air.
  • O.O.C. Is Serious Business: yo-ka is known to frequently fly off the handle and write rather scathing blog posts without really thinking. However, before the band's first oneman, he wrote a very angry post, then wrote another one on the next day. During the oneman, yo-ka was distant, putting a wall between himself and the audience, as if he wanted nothing to do with the fans. It was everything but a spur-of-the-moment thing. The reason he did this? Fans were bullying eachother and even criticized Diaura itself for not being enough like Valluna.
    • Among some of the things yo-ka wrote on his blog were "I can't ask a large group of humans to love eachother, but I at least expect you to act like civil adults.'' and "How long are you going to drag Valluna behind you?!").
  • Protest Song: Most of their political songs wander into this teritory, but DEAR RULER takes the cake and eats it too.
  • Precision F-Strike: evil contains one of these:
    This awakened evil will eat everything until it's exhausted/ The gun barrel was thrust/ Fuck out "God of Fake"
  • Real Song Theme Tune: Sajou no Yume has been used as the intro to a game called "Rebirth of the World".
  • Rearrange the Song: All over the place. Fans have even pointed out how Diaura can re-record Shitsuyoku no Seiiki three times and it would still sound cool.
  • Red Oni, Blue Oni: Kei is the blue to yo-ka's red.
  • Rule of Symbolism: See "Mood Whiplash" above.
  • Sequel Song: SIRIUS, to Garden of Eden.
  • Spoken Word in Music: Many songs feature yo-ka speaking. And then there's DICTATOR, which has a speech by Adolf Hitler inserted into it.
  • Sound Effect Bleep: Ms. Psycho contains one of these.
  • Soprano and Gravel: yo-ka can do this all by himself.
  • Stylistic Suck: Their PVs are generally regarded as this. While Visual Kei videos usually tend to get the short end of the stick when it comes to creativity and this is no real exception, Diaura at least reinterprets all the cliches in style.
  • Subdued Section: Quite a few times, but most notably in RUIN.
  • Tarot Motifs: The cover of Evils depicts The Hanged Man.
  • Teen Genius: Kei had his first live show when he was fifteen. yo-ka, when he was sixteen.
  • The Revolution Will Not Be Civilized: DEAR RULER is made of this trope.
  • Trademark Favorite Food: More like Trademark Favorite Drink, in the case of yo-ka. His fondness for melon soda has reached memetic status within the Diaura fandom.
  • Unplugged Version: The acoustic version of Lost November.
  • Unstoppable Rage: DEAR RULER. All of it.
    Sell face/ You are low/ Sell face/ In massmurder/ Sell face/ You are low/ Sell face/ I'll drink your blood.
  • Villain Song: DICTATOR is written from the perspective of Adolf Hitler.
  • Vocal Tag Team: yo-ka can't seem to decide between tag-teaming with either Kei or Shoya and being a Self-Backing Vocalist.
  • Those Wacky Nazis: Due to the band's overall concept, Nazi uniforms tend to show up quite a bit.
    • Taidou is about the experiments the Nazis did on Jewish babies in an attempt to make them Aryan.
    • DICTATOR is written from the perspective of Adolf Hitler. See "Villain Song" above.
  • Word Salad Lyrics: a genesis of the end is written almost entirely in this.
  • You Gotta Have Blue Hair: Tatsuya in the PV for black sheep under the shallow sleep.
