Both are comedic counterpart series to their respective parent series and have short episodes (approx. 5 mins) consisting of non-stop gags based on a "toon"/"chibi" style of animation. Note that the Brotherhood series is a collection of parodies of significant events pulled from the main story while the Suzumiya series is a compilation of short side stories set apart from the main story.
