Hyadain (born July 4, 1980) is a [[WidgetSeries Japanese]] singer, arranger, {{composer|s}} and music producer, well known for his work on game music, with often very liberal (and frequently hilarious) interpretations of characters in the games. He posts all his work on both [[http://www.nicovideo.jp/user/1374465 Nicovideo]] and [[http://www.youtube.com/user/hyadain2525?blend=1&ob=4 Youtube]].

His most famous works are probably the various songs he did for ''VideoGame/MegaMan2'' (6 out of 8 Robot Masters, so far), where each Robot Master sings a song basically professing their love to Mega Man (except for Bubbleman, who's just incredibly lonely, and Heatman... who seems to be a giant man-slut). He also has a large number of songs that are arrangements of various ''VideoGame/DragonQuest'' songs (and as a bit of trivia, his nickname is derived from the Japanese spell name of "[[AnIcePerson Kacrack]]"). He also sang a good number of covers of old anime songs. He does all the voices himself, using computer editing to make the female voices.

He eventually revealed [[http://ameblo.jp/hyadain/ on his blog]] that [[SecretIdentity he is in fact]] '''Kenichi Maeyamada''', a professional composer in the Japanese music industry, which [[IKnewIt was suspected by a good many of us]] due to the incredible quality of his work. He signed under the management Stardust Promotion, which also the home of Natsuko Aso and Music/MomoiroCloverZ, sources of his main works and his biggest hits. Because of his distinct [[EarWorm happy upbeat musical]] style, his works often involves various IdolSinger, such as the two mentioned above, Music/AKB48, [=YuiKaori=] and Koharu Kusumi of Music/HelloProject, 9nine, Dempagumi Inc. and Shiritsu Ebisu Chugaku. He has worked on a LOT of Japanese anime theme songs, including the 10th opening for ''Manga/OnePiece'', "Share the World", and remarkably ''Manga/{{Nichijou}}'''s [[http://www.youtube.com/watch?v=1Xxnp0Q1GYQ theme]] where he actually made his name known among foreign fans. He switches between a good number of styles, though the majority of his songs are intended to be funny or cutesy, with [[HurricaneOfPuns lots of puns everywhere else]]. he can also do heart-wrenching ballads and darker-themed songs.

His [[http://maeyamada.com/ professional website]] lists his complete discography outside of his game music arrangements.

!!His work provides examples of:

* AlbumIntroTrack: ''20112012'' is opened by a track titled "[[IdiosyncraticEpisodeNaming 19802011]]", it's all SpokenWordInMusic and delivered in the style of OpeningNarration, describing Hyadain's biography.
* AlterEgoActing: The name "Hyadain" is only used when Maeyamada both creates and writes the song and for his internet pseudonym; when he only composes ''or'' writes the song, he uses his real name.
** The female vocals that are often heard in many of his songs are provided by "Hyadaruko". Although she is portrayed by actresses (such as Natsuko Aso in "Kakakata kataomoi-C" and Akari Hayami of Momoiro Clover Z in "Jyojyo Yuujo") in music videos, "Hyadaruko" is actually ''[[CrossDressingVoices Hyadain]]'', by altering his voice pitch.
* AnimeThemeSong:
** As a professional composer and writer even before his viral WebSite/YouTube hits, he has actually a ''lot'' of anime themes under his belt. To name a few examples, "Don't Go Baby" from ''Manga/InitialD'', "Tan Tan Taan!" and "Happy Happy Sunday" from ''Manga/KirarinRevolution'', and "Perfect-area Complete!" from ''[[LightNovel/BakaAndTestSummonTheBeasts Baka And Test]]''.
** And then, he has his other hits when he managed to debut as a professional singer in ''Manga/{{Nichijou}}'' for "Hyadain no Kakakata kataomoi-C", such as "Start it right away" for ''Manga/KurokoNoBasuke''.
* AuthorAppeal: [[EveryoneIsGay Gay]], [[HurricaneOfPuns puns]], and [[WidgetSeries weird idols]].
* AutoTune: He's a god at this stuff.
* BigBrotherMentor: He happens to be a faithful music mentor figure for Natsuko Aso, Momoiro Clover Z, and Ebichu, in a friendly way as if they were [[TrueCompanions companions]]. There were an instance when a member jokingly punched him and complained "I want more singing parts!". He even wrote several songs based on their life and their gimmicks.
** He also [[EducationMama helped them to do their school homework]].
** During a live concert of Momoclo, [[SoProudOfYou he shed tears]] when his song was being performed.
%%* BigOlEyebrows
* CallBack:
** Each of the ''Mega Man 2'' songs (excluding the first, for reasons about to be made fairly obvious) contains a brief sample of the song that came before it towards the end of them, with varying degrees of subtlety.
** Almost all of his songs for Music/MomoiroCloverZ features call backs to each other and other works as well. Apparently he loves doing stuff like this.
* ChildProdigy: He is a true music genius. He began playing the piano at age four, he first composed a song with a synthetsizer in middle school, and [[CrazyAwesome only needed a single day to complete a song]].
* {{Chiptune}}: Maeyamada loves retro gaming, no one has to wonder why he features a lot of chiptune in many of his songs' arrangements.
** "Ano Hi no Boku He" opens with a chiptune.
** The track "Hyadain Quest" is a chiptune {{medley}}-song from his hits.
** [[https://www.youtube.com/watch?v=dF3XwRsYeb0 His opening song]] for the Japanese dub of ''WesternAnimation/PacManAndTheGhostlyAdventures''. Not surprising since it's for, well, [[CaptainObvious a show based on Pac-Man]].
* ChristmasSongs: As mentioned above, "Xmas? I don't know such a thing!!" and [[Music/MomoiroCloverZ Momoclo]]'s "Santa-San". Bonus points are that both songs share many public domain Christmas carols all over the place, as the latter is recycled from the former and filled with many [[MythologyGag Mythology Gags]]. To add the hilarity, the music video for the 2011's version of "Xmas?" features many [[CameoProp Momoclo's props]].
* CoolHat: He is almost always seen using a cool cap.
* DarkerAndEdgier:
** Many of his post-2012 songs are very noticeable to feature downer lyrics and drastic arrangement changes from [[MoodWhiplash his usual style]], such as "Start It Right Away" and "23:40".
** Taken to the extreme in Momoclo's ''Hai to Diamond''. It's a heavy ballad, with partly despaired lyrics and misplaced vocals, if you compare it to [[http://www.youtube.com/watch?v=LwMuHy8t_Vk his]] [[http://www.youtube.com/watch?v=u7z9M0vFPbI earlier]] [[http://www.youtube.com/watch?v=jCwI7y0Oy5Q songs]] [[http://www.youtube.com/watch?v=oCRlKdMnPLI back then]] (when the fans called it "Hyadain-Era Momoclo"). Many people even think " is this seriously a song by Hyadain?".
* DontLookAtMe: He doesn't like to be looked at when he is doing the recording.
* EveryoneIsGay: The ''Mega Man 2'' series of songs. Well, except for Heat Man...
* EpicInstrumentalOpener: Momoclo's "Overture" and Ebichu's "Ebichure"
* GratuitousEnglish: His English sounds ''pretty'' good, but that's not saying a whole lot.
* HomoeroticSubtext: Sliding into HoYay, a good number of his songs (particularly his series of ''Franchise/MegaMan'' songs, but also his ''Goemon'' and ''VideoGame/FinalFantasyIV'' tracks) displays many (if not ''all'') of the characters involved as gay or [[BiTheWay bisexual]].
** He also has done a [[http://youtu.be/26IPBZAfsbE song (sequel to "Hyadain no Kakakata kataomoi-C")]] about two good friends, one of whom has just gotten a girlfriend (but seems to be only complaining about her) while the other doesn't seem to be ''just'' jealous of him...
* HurricaneOfPuns: He loves to make tons of puns, that are almost everywhere in his songs, making them part of his [[AuthorAppeal trademarks]].
* IMinoredInTropology: He is a major... [[DidntSeeThatComing in sociology]].
* LarynxDissonance
* LetsDuet: While doing a song with Hyadaruko isn't ''exactly'' a [[SoloDuet duet]], a number of the songs that are also featured in ''20112012'' are duet songs with several musicians (like VERBAL from m-flo) and Creator/HiroShimono.
* LuckyCharmsTitle: Many of Hyadain's songs feature a "☆" star symbol somewhere else, to name a few, "Hyadain no Kakakata☆kataomoi-C", "Koko☆Natsu", "Shooting☆Smile" and "Happy☆Happy Sunday!".
* ManOfAThousandVoices: Justified as he uses a digital voice modifier.
* {{Medley}}: His "Hyadain Quest" song. He also composed "Momoiro Kohaku Da Z!", a medley song for Momoiro Clover Z that was performed in Kohaku 2012.
* NeverTrustATitle: "Samba De Toriko" isn't a samba, and has nothing to do with ''Manga/{{Toriko}}''...
* PopStarComposer
* RailEnthusiast: He's a founder of "Stardust Train Club", a community of train lovers from his agency.
* RecordProducer: More specific, he is an ''Idol'' producer. He was also the producer for Natsuko Aso and Momoiro Clover Z and was the responsible for bringing their untarnished energetic and cheerful reputation. Now, he is handling Dempagumi Inc. and is the main producer for Takoyaki Rainbow.
* SequelSong: The boy that suffers unrequited love in "Hyadain no Kakakata kataomoi-C" finally gets a girlfriend in "Riajutte Konna Mon Dakke?".... and it looks like he is not completely ''happy'' about it.
* ShoutOut:
** As a Youtube commenter puts it:
-->"I still love the fact that even after Hyadain got into the anime business, he still abuses the Yaranaika meme to no end."
** In Dhalsim's portion of the "World Warrior" song, you can clearly hear the lyric "[[Manga/OnePiece Gomu Gomu no Mi]]". Also, Zangief's section borrows one of the original Tetris background melodies.
** The video for "Riajutte Konna Mon Dakke?" uses also a reference to ''Franchise/{{Pokemon}}'' and ''Manga/OnePiece''.
** A very common part of his video game parody lyrics. Listing all of the times he has referenced and namedropped various shows and their memes would probably take years.
* SingerNamedrop: His artistic name is even dropped in the songs' titles.
* SongStyleShift: This is how most of his works become distinctively fun, Momoiro Clover Z's "[[http://www.youtube.com/watch?v=KUoy582ePlQ "Mirai Bowl]]" is a good example.
* SongParody: "Hyadain no Kakakata kataomoi-C" is self parodied ''two'' times. "Hyadain no Kakakata kataomoi-F", which is the B-side of the main song's single is basically a TruckDriversGearChange vocals from C (Hyadain) to F (Hyadaruko). And "Kataomoi-Bon" is sung by [[DrunkenSong a drunk man in Karaoke outlet]], which is included in ''20112012''.
* SpokenWordInMusic: Also one of his trademarks.
* StupidSexyFlanders: A lot of people ignore that the "sexy female vocals" in many of Hyadain's songs are actually just him using a voice program to alter his voice's pitch (likely to be ''Melodyne'').
* StopAndGo: "Xmas? I don't know such a thing!!".
* SummonBackupDancers: Many of his music videos.
* SurprisinglyGentleSong: "Hamigaki".
* TakeThat: Maeyamada is currently producing [[DoesThisRemindYouOfAnything another six color-coded idol group]] called Dempagumi.Inc, and he is composing most of their singles. The reason he did that was because he quit from producing Music/MomoiroCloverZ after he had a couple of problems with their management. Hilariously, he's recently gotten back with Stardust producing for their newer idol group and fellow Kansai residents Takoyaki Rainbow, who are very much like Momoclo but without any red member.
* TitleByNumber: His first album is titled ''20112012'', a reference to many of his major works that started in 2011. And the first track that it has, is called "19802011".
* TitleThemeTune:
** He is responsible for the main theme songs for many of the idols he produced, that the listeners would unlikely forget. The lyrics tend to [[ExpositoryThemeTune describe what kind of idols they are]] and they even [[ListSong list the members]]. Primary examples are Momoclo's "Kaitou Shojo" and "Z Densetsu" (the latter being an updated version after the group's lineup changed), Ebichu's "Ebizori Diamond", Takoniji's "Zesshou!", and Dempagumi's "W.W.D".
** This is a practice that has also been carried out throughout since his WebSite/YouTube mixing days. Almost all of his remixes' lyrics are [[ExpositoryThemeTune expository]].
** He wrote Music/{{Sphere}}'s "Ding Dong! Ding Dong!" for their fourth album, where each member get to showcase their respective preferred solo genre (rock, J-pop, pop, and opera), all in the same song. Not surprisingly, it became the only song from that album that was voted and submitted by Sphere's fans to their Greatest Hits collection, only a few months later.
