D is a Japanese Visual Kei band formed in 2003 by Asagi, Sin, and Ruiza, after their previous band, Syndrome, broke up.
In March 2003, D was formed with the first five members, Asagi, Ruiza, Hiroki, Sin, and Rena. They released their first mini-album, New Blood, on 18 July 2003. Soon after the release of this album, Ruiza was hospitalized, and Sin decided to leave the band. The band took a small break. During this break, Asagi and Hiroki played under the name "Night of the Children" with the guitarist Hide-Zou, which Hiroki knew from S to M. When Ruiza was released from the hospital, D came back together on 27 September 2003 with a new line-up, Asagi, Ruiza, Hiroki, Hide-Zou and Rena. 2 months after their reunion, they released their first single, "Alice". On January 7 they released their second mini-album Paradox.
During 2004, D released two other singles: "Yume narishi kuuchuu teien," and "Mayutsuki no hitsugi," which was only for sale at three concerts in Shibuya O-West (11.04), Nagoya ell. FITS ALL (11.13) and Osaka MUSE (11.23). They also decided to release a remastered version of their first mini-album, but this time with the bonus track "Gareki no hana". New Blood ~second impact~ was released on Dec 08, 2004, quickly followed by their fourth single Mahiru no koe ~Synchronicity~.
In 2005, Rena was in the band long enough to release one more single and PV, "Yami yori kurai doukoku no a CAPPELLA to bara yori akai jounetsu no ARIA". After the recording of their latest album, Rena decided to leave the band July 27. On September 28 D's first full album The name of the ROSE was released in 2 versions each with a DVD of a different PV. D also launched their own publication, the Mad Tea Party Magazine.
Tsunehito joined D on 5 December 2005 and re-recorded the bass lines for The name of the ROSE 2006, which included three new tracks.
Keeping with the trend of remastering their old albums, in 2006 they re-released Paradox and "Yume narishi kuchuu teien". The latter came with two additional tracks that were previously unreleased. Their 7th single "Taiyou wo okuru hi" was released in two forms: with and without the PV. Two months later they released their second album, Tafel Anatomie on October 18, 2006 in which its first press special edition was sold out within days.
For 2007, D launched their official fanclub "Ulitimate Lover" and released their first live DVD, Tafel Anatomie TOUR 2006 (2007.3.14). Soon after, the band announced in-store events and a three-date tour (Osaka, Nagoya, Tokyo) on their website to support their new single, "Dearest You" (2007.04.25). In the summer, D released 2 more singles, "Ouka sakisomenikeri" (2007.07.18 )[1] and "Schwarzschild" (2007.08.15). In November D released their 3 full length album Neo culture〜Beyond the world〜(2007.11.07) in 3 forms: 2 special editions each containing a DVD with different PVs and a regular edition with a special 36 page booklet.
In 2008, D signed with Smile records and has gone major. Their major label debut is set for May 7, 2008 and will be called "Birth". The single is released in 3 forms, the first being an A-side, a B-side, and a PV. The second will include a bonus track, and the third will include another bonus track.
