For those looking to collect the series, retailers like eBay and specialty shops such as Playtech-Asia offer "Uncut" DVD sets that bundle both the TV and OVA series.
These were released as limited edition bundles with manga volumes between 2008 and 2015. This series is considered the "legendary" version by fans for being much more explicit and having fewer broadcast restrictions.
