Plenty more IKU info from Amazon Japan

Amazon.co.jp has almost everything you need to know about IKU and her debut single.*
First, the full name of the single is “音のない夜空に/木の芽風” which means that her contribution to Hayate no Gotoku! is actually the b-side of the single.
Next, we have an actual cover picture as well as an additional photo of IKU herself. Apart from fashionably warm boots and the large leaf, there is romaji of the title which reads “oto no nai yozora ni / ko no me kaze.” Yes, that is the proper reading. “木の芽” according to my JWPce dictionary reads as “このめ” with definition “(n) bud of Japanese pepper tree (Xanthoxylum piperitum), leaf bud.” So there you go: “Leaf bud wind,” which kind of goes along with the cover art. “Oto no nai yozora ni” roughly means “In the silent night sky,” and I’m 99% certain that it’s the opening theme to “プリン・ス.” Yes, Geneon seems to be releasing a CD for an avex property, we’ll see how that’s taken care of. The credits for this song haven’t been released yet, so for all we know it might not even be I’ve. Stay tuned.
In addition to the same blurb that Neowing posted some time ago, Amazon gives more info on IKU herself:
(caution: rough translation)
“From the age of five, she has played the electric organ and in sixth grade (sixth year of primary school) won the All-Hokkaido tournament. Continuing from her early years, she entered a wind ensemble and thus has experience in many instruments. This was the foundation of her music. Forming a band in senior high, she discovered how much fun it is to be a singer. Then in university, she became aware of her professional skills. While at a vocal school, she revived her skills in piano performance, and around 2006 started to produce her own cover songs, providing the vocals at live performances. This caught the attention of Kazuya Takase, the Sapporo-based producer who has made many hit songs, and so she made a demo tape.
This song to promote the popular TV anime “Hayate no Gotoku!” will therefore be her major debut.”
She sure seems to have enough talent, and though “ko no me kaze” isn’t all that strong of a debut, recall that most I’ve vocal-himes hadn’t fully refined their skills until after a few releases. Sora wo tobetara, anyone? Playing teacher’s pet to Shimamiya-sensei** doesn’t hurt a bit, either.
“oto no nai yozora ni / ko no me kaze” releases on March 19.

* If that behemoth of a link doesn’t work, do a search on Amazon for “GNCL-29” and the title should pop up.
** I know it hasn’t been confirmed, and probably won’t be confirmed, but to me it’s blatantly obvious.
