The fifth season of the Bleach anime series is named the Bount Assault on Soul Society arc. In the English adaptation of the anime released by Viz Media, the title of the season is translated as the The Assault. The episodes are directed by Noriyuki Abe and produced by TV Tokyo, Dentsu, and Studio Pierrot. Unlike previous seasons in the series, this season and season four are fillers which are not direct adaptation of the Bleach manga by Tite Kubo. Instead, the episodes’ plot focuses on the invasion of Soul Society, the home of the Soul Reapers, by the Bount, a race of humans that consume human souls to extend their lives.
The arc initially ran from August 8, 2006 to January 4, 2007 in Japan on TV Tokyo. It lasted eighteen episodes. The English adaptation of the season began airing on December 13, 2008 on Adult Swim and ended on April 11, 2009. Four DVD compilations of the season were released by Aniplex between January 24, 2007 and April 25, 2007 in Japan. The first two DVD compilations contain four episodes of the season, and the last two contain five episodes. Viz Media released this season in four DVD volumes from December 15, 2009 to March 23, 2010. A DVD box set of the season was released on June 8, 2010.
