Rentrer en Soi (リエントール アン ソイ) was a Japanese visual keirock band active from 2001 to 2008. In French, the band's name can be literally translated as "to enter in yourself/entering yourself" although this is not grammatically correct. The band was composed of five members, and had seen only one member change.
In 2001, the band started out with only four members—Satsuki, Takumi, Ryo, and Ao. In March 2003, Mika joined the band as the drummer and not long after they caught interest of Yukari from Baiser to be their producer.[2] At the end of a tour in February 2004, Ao left the group due to "undesirable behavior". He was replaced by Shun within a month. At the end of that year the band started recording what would be their first album, Sphire Croid, released in early 2005. Later that year two EPs were released, Astre no Ito and Kein no Hitsugi, then Yukari stopped being their producer.[2]
The following year the band released its second album, Rentrer en Soi. The band was signed to European record label, Gan-Shin in 2006,[3] and later to the American division of Free-Will. In 2007, the band's final studio album, The Bottom of Chaos, was released in Japan as well as Europe.[4]
On October 19, 2007, the band played at the Oni-Con convention in Houston, Texas. This was their first concert in the United States.[5]
2008 began with the announcement of their single, "Stigmata", released in March, as well as a coupling tour, "Tour 2008 Death Match", with Unsraw through Japan.[6][7] The band was announced for the Free-Will event, "Clash Against Commercialism" at Nokia Theatre Times Square in New York City, however the event was cancelled two weeks prior due to difficulty obtaining visas for the musicians.[8] Shortly after, Rentrer en Soi again announced they would perform in the United States for the AnimeNEXT convention.[9]
On September 17, 2008, Rentrer en Soi announced that they would be breaking up. In October hey released a final EP, Megiddo, a best-of album titled Ain Soph Aur on November 19, 2008 and their last live was planned for December 25, 2008.[10] The track list for Ain Soph Aur, their best-of album, cannot be viewed on their website. Ain Soph Aur features Kuuhaku no Joukei, a track that was not originally included on Yurikago, however it was featured as a PV on Cinema Cradle.[11]
Satsuki started a solo career and became the vocalist of Kisaki Project,[12][13] while Takumi and Mika both joined the supergroup Sukekiyo in 2014.[14]
