is the 28th single by Japanese heavy metal band Dir En Grey, released on December 19, 2012. Its highest ranking reached fourth place on the weekly Oricon chart.[1] The original cover art is created by vocalist Kyo, which was shown at various venues in Japan after release of the single.[2]
The release of Rinkaku introduced a new version of Dir En Grey releases. In addition to the regular and first press limited versions, it was also released as a made-to-order limited version . This version comes with unique packaging and additional contents, in this case a number of live-recorded tracks from one of the band's 2011 shows. Their next two releases, The Unraveling and Sustain the Untruth, also came in these three versions.
However, with the release of Dir En Grey's next studio album Arche in 2014, a Blu-ray variant became available in addition to the DVD variant of the made-to-order limited version. Subsequently, this version was replaced by the limited production version, a designation which had been used in the past for the Decade best-of album, as well as the LP-version of Uroboros and Dum Spiro Spero. Since Arche, all of the band's albums and singles have been released as a regular version with just the main disc, a first press limited version with a bonus CD or DVD, and a limited production version with a bonus CD, DVD and/or Blu-ray.
