Saiyuuki Reload Blast is the fourth Saiyuuki manga series that has been serialized under Ichijinsha's Monthly Comic ZERO-SUM josei magazine since December 2009. It is the sequel of the manga, Saiyuuki Reload, which ran from March 2002 to June 2009 in the same magazine.
The original manga series, Saiyuuki was serialized under Square Enix' Monthly GFantasy shounen manga magazine from February 1997 to January 2002 with nine compiled volumes. The manga was followed by a second series, Saiyuuki Gaiden, which served as its prequel set 500 years before. The series was serialized in the same magazine from May 1999 to May 2009 with four volumes. The fifth and final series, Saiyuuki Ibun, was serialized under Ichijinsha's Monthly Zero-Sum WARD magazine since September 2009. However, the fifth series went on hiatus in 2013, and the magazine has ceased publication since 2015.
The series has previously received multiple anime adaptations. The first was a two-episode OVA by Tokyo Kids. The episodes were released on April 23, 1999 and August 27, 1999. The OVA was followed by a 50-episode TV anime adaptation of the original manga series, titled Gensoumaden Saiyuuki, by Studio Pierrot which aired from April 2000 to March 2001.
