Secret is the first predominantly-pop album by Kumi, with her first three albums,
feel my mind,
grow into one and
affection, being
R&B. Due to Kumi feeling most comfortable with the style she donned in "
Crazy 4 U", she created the "sexy-cute" style (known as ero-kawaii) for her
A-sides used in
secret. This is the style that she became famous for and received both positive and negative attention. During her performance for "
Cutie Honey" at
Music Station, she donned the outfit she wore during the jazz parlor scenes in the Music video. The outfit was heavily criticized, when revealing clothing was not worn by mainstream artists in Japan at the time. On April 13, 2005, three special editions of the album were released, which contained the Music video for "
Hot Stuff", which featured the rapper
KM-Markit and, depending on which special edition was purchased, came with a
T-shirt or a
tank top. The DVD contained the Music videos originally released on her first
DVD single, "
Girls: Selfish": "Selfish", "Shake It" and "24". The song "24", which was written and composed by the arranger Hitoshi Shimono, was the first song released by Kumi with an entire chorus in English. She worked with Hitoshi again for her 2006 song "
Feel", which also contained a chorus completely in English. ==Packaging==
