Hyadain is a Japanese singer, arranger, composer 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 Nicovideo and Youtube.His most famous works are probably the various songs he did for Mega Man 2 (6 out of 8 Robot Masters, so far), where each Robot Master sings a song basically professing his love to Mega Man (except for Bubbleman, who's just incredibly lonely, and Heatman...who just seems to be a giant man-slut). He also has a large number of songs that are arrangements of various Dragon Quest songs (and as a bit of trivia, his nickname is derived from the Japanese spell name of "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 on his blog that he is in factKenichi Maeyamada, a professional composer in the Japanese music industry, which 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 Momoiro Clover Z, sources of his main works and his biggest hits. Because of his distinct happy upbeat musical style, his works often involves various Idol Singer, such as the two mentioned above, AKB48, YuiKaori and Koharu Kusumi of Hello! Project, 9nine, Dempagumi Inc. and Shiritsu Ebisu Chugaku. He has worked on a LOT of Japanese anime theme songs, including te 10th opening for One Piece, "Share the World", and remarkably Nichijou's theme where he actually made his names 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 lots of puns everywhere else. he can also do heart-wrenching ballads and darker-themed songs.His professional website lists his complete discography outside of his game music arrangements.
Alter Ego Acting: The name Hyadain is only used when he both creates and writes the song and for his internet pseudonym; when he only composes or writes the song, he uses his real name.
There is also Hyadaruko, the female vocals often heard in many of his songs, although in the music videos were played by female actress (such as Natsuko Aso in "Kataomoi-C" and Akari Hayami of Momoiro Clover in "Jyojyo Yuujo"), they're actually his voice.
Anime Theme Song: and how, his professional job started back even before his viral youtube hits, also noted for his eccentric upbeat tunes in his works, to name a few in the early days, " “Don’t Go Baby” of Initial D, "Tan Tan Taan!" and "Happy Happy Sunday" of Kirarin Revolution, "Perfect-area Complete!" of Bakatest to the recent Bakuman。 opening.
And eventually he managed to become a regular in annual anime music festival, Animelo after his real debut as singer in Nichijou themes.
Big Brother Mentor: 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 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.
Breakthrough Hit: For his own: "Hyadain no "Kakakata☆kataomoi-c", for Natsuko Aso: "Perfect-area Complete", and for Momoclo: "Ikuze! Kaitou Shoujo".
Call Back: 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 song for Momoiro Clover Z features call back to each other and works like above. Apparently he loves doing kind of things like this.
Christmas in Japan: His "Xmas? I don't know such a thing!!" is about being alone on Christmas.
Christmas Songs: again, "Xmas? I don't know such a thing!!" and Momoclo's "Santa-San". Bonus points that both share many public domain Christmas carols all over the place, as the latter is recycled from the former and filled with many Mythology Gag. To add the hilarity, his music video features many Momoclo's props.
Taken into extreme in Momoclo's Hai to Diamond, heavy ballad, partly despair lyrics and misplaced vocals, contrast to hissongsbackthen (when they called it Hyadain-Era Momoclo) even the fans thinks "seriously is this a Hyadain's doing?".
Genre Savvy: He knows what fans wants when writing song for idol groups, He often leaves parts obviously intended for fans chant or known as wotagei, in example Dempagumi's "W.W.D", Momoclo's "Mouretsu", and Ebichu's ""Houkago Getabako Rock 'n' Roll MX".
Rail Enthusiast: also a founder of Stardust Train Club, a community of train lovers from his agency.
Record Producer: Specifically mentioned, he is an Idol producer. He was a producer for Natsuko Aso and Momoiro Clover Z and responsible for bringing their untarnished energetic and cheerful reputation. Now he is handling Dempagumi Inc.
Sequel Song: The boy that suffers unrequited love in "Kataomoi-C" finaly get a girlfriend in "Riajuu".
Take That: He is currently producing another six color-coded idol group, Dempagumi.Inc, and created most of their singles. This is an obvious take that to Momoiro Clover Z's management after he had a problem with them.
Title by Number: His first album is titled 20112012, a reference to many of his major works that started in 2011.
