List of Bleach episodes (season 4)

The fourth season of the Bleach anime series is named The Bount arc (バウント篇). The episodes are directed by Noriyuki Abe and produced by TV Tokyo, Dentsu, and Studio Pierrot. This season, along with season five, is not a direct adaptation of the Bleach manga by Tite Kubo; the plot focuses on the introduction of the Bount, a race of humans that consume human souls to extend their lives, and their conflicts with Ichigo Kurosaki and his allies. This season lasted twenty-seven episodes.

Viz Media started publishing these DVDs on May 12, 2009 with them containing both English and Japanese languages.
