List of Bleach episodes (season 7)

The seventh season of the Bleach anime series is named the Arrancar: The Hueco Mundo Sneak Entry arc (破面・虚圏 潜入篇). In the English adaptation of the anime released by Viz Media, the title of the season is translated as the The Hueco Mundo. The episodes are directed by Noriyuki Abe and produced by TV Tokyo, Dentsu, and Studio Pierrot. The twenty episodes featured in the season are based on Tite Kubo's Bleach manga series. The episodes' plot follows Ichigo Kurosaki's journey to Hueco Mundo to rescue Orihime Inoue, who was kidnapped by the arrancar under the command of former Soul Reaper captain Sōsuke Aizen. Although episodes focused on the character Ashido Kanō were not featured in the manga due to timing issues, Kubo still helped the anime staff to show it in the anime.

The season began airing on July 4, 2007 in Japan on TV Tokyo and ended on December 5, 2007. The English adaptation of the Bleach anime is licensed by Viz Media, and this arc began airing on July 11, 2009 and ended September 26, 2009 on Adult Swim. Five DVD compilations, each containing four episodes of the season, were released by Aniplex between December 19, 2007 and April 23, 2008 in Japan.

The episodes use four pieces of theme music: two opening themes and two closing themes. The opening themes are "Alones" by Aqua Timez, used for the first twelve episodes, and "After Dark" by Asian Kung-Fu Generation, used for the remaining episodes. The ending themes are "Daidai" (橙) by Chatmonchy, utilized for episodes 132 to 143, and J-pop singer Kousuke Atari's "Tane wo Maku Hibi" (種をまく日々), used for the rest of the episodes.
