Biography

Before Naifu came together, its members were involved in the indie music scene: Siyon led the solo project SCHON and played in the rock group Mr.Orange, while Naoki served as a guitarist for Elf.

On April 9, 2008, both Siyon and Naoki contributed chorus vocals and arrangement work on Zard’s posthumous single Ai wa Kurayami no Naka de, which was selected as an opening theme for the widely recognized anime Detective Conan. The single began airing in January 2009.

Shortly thereafter, on April 23, Naifu independently released their debut mini-album titled "All Over Now EP" through Tent House. The leading song Hikaru Ao ni Tobidase was featured as the ending theme on the television music show JAPAN COUNTDOWN.

In May 2008, Siyon and Naoki appeared as guest performers during Zard’s "What a beautiful memory 2008" concert; this performance was later issued on DVD in 2011.

Naifu officially entered the major label scene in July 2008 with their single Take The Wave under Giza Studio. During the recording process, keyboardist Takumi left the band, resulting in the final artwork showcasing only four members. This track was chosen as an opening theme for the anime Golgo 13.

Their follow-up single Mysterious, released in November 2008, became their most notable success, serving as another opening theme for Detective Conan. It attained a peak position of #36 on the Oricon Weekly Charts and remained for seven weeks. Additionally, Naifu appeared on Tokyo Broadcasting System’s music program Count Down TV.

The third single, Koigokoro Kagayaki Nagara (February 2009), was used as an ending theme for Detective Conan but experienced lower commercial performance, charting for just two weeks.

In March 2009, Naifu issued their only full-length studio album titled One.

Their last single, Sunset/Ari no Mama de, was released in June 2009 and featured as an opening theme for the program Music Fighter.

In November 2009, through their official blog, Naifu announced their decision to disband effective December 31.

Following the disbandment, Atsuhi joined several rock bands including WAR-ED (2010–2011), Loe (2013–2014), and has performed with Dps since 2017 under the name Atsushi Kawamura. Siyon transitioned into a producer role for singer Aya Kamiki. Fuma participated in Hazze (2010–2013) and Purple Stone (2013–2018). The subsequent activities of Naoki and Takumi after 2009 remain undisclosed.
