"Rinkaku" (輪郭, "Contours") 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 (通常盤 (Tsūjō-ban)) and first press limited (初回生産限定盤 (Shokai Seisan Gentei-ban)) versions, it was also released as a made-to-order limited version (完全受注生産限定盤 (Kanzen Juchū Seisan Gentei-ban)). 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 (完全生産限定盤 (Kanzen Seisan Gentei-ban)), 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.

• Kiri to Mayu (霧と繭) is a re-recorded version from their debut EP Missa.
• All live performances featured on the deluxe DVD are from the Tour 2011 Age Quod Agis concert "Ratio ducat, non fortuna" at Tokyo Dome City Hall on 2011.11.11.^[3]
