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.


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, composer, co-founder and arguably the most well-known member of the band. He can 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 used to be part of bands ADOLF, CRIMSON, Bunny Drug and Valluna.
  • 翔也 (Shoya): bassist, occasional backing vocalist, and yo-ka's Chew Toy of choice. He has played guitar in several bands before he joined Dizly as a bassist under the name Yukito. 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 for a long time.

  • 達也 (Tatsuya): drummer, occasional backing vocalist and occasional composer (he has composed the song "The Redemption", "Daybreaker" and "Ares or Thanatos"). He was formerly part of the bands DIS Marionette, Gakudan Hitori, and Ronove.
  • 勇 (Yuu): drummer and co-founder alongside yo-ka and Kei, he left Diaura after just one year due to tendinitis, and was replaced by Tatsuya. He started out in Marely alongside yo-ka (under the stage name "Aya") and followed him in Valluna.

Please Call My Tropes:

  • Alliterative Title:
    • Sakura Sacrement.
    • Shitsuyoku no Seiiki.
    • Todokanu Tegami.
  • All Just a Dream: The ending of 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.
  • The Atoner: Todokanu Tegami, Rakuin-stigma- and Shiro to Ao no Kyoukai all revolve around this trope, but the most blatant example by far is The Redemption.
  • 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".
  • Break-Up Song: Infinite is probably the most notable example.
  • Breakout Character: Tatsuya. He started out as a mere Replacement Goldfish for Yuu, but now most of the fans just can't imagine anyone else as the drummer.
  • 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. See Madness Mantra below.
  • Can't Hold His Liquor: yo-ka stated that he has a low alcohol tolerance.
  • Catchphrase: 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 (Hanamadoi) 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 a short-lived indie band called 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 for a long time, 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"
  • 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, then killing oneself because the scars left are too much (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. Since it's 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 or dark songs. This results in most of their singles being this trope. In fact, the only notable aversion is Silent Majority.
    • As yo-ka would put it: "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."
  • 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 or Inferiority Complex.
  • 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 meowing. 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 pretty much 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: Many DIAURA songs reference Christianity in some way, but none of the DIAURA members are known to be Christian.
  • OOC 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, 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.
  • Shrinking Violet: yo-ka, when he was a child. Yep. It's true.
  • 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 is able to do this all by himself.
  • Subdued Section: Quite a few times, but most notably in RUIN and IKAROS no yume.
  • 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 frequently tag-teams with either Kei or Shoya.
  • 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.
