Anime Omakes
Each Bleach anime episode features a short comedic omake segments, which is like a mini-episode that air at the end of the episode. They offer extra information about the episode, such as techniques or more character information. They also show other characters in different situations, such as the Shinigami Women's Association. Some omakes are also manga-based.
