The seventh season of the Bleach anime series is named the Arrancar: The Hueco Mundo Sneak Entry arc. 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 them in the anime.
