Asobi Asobase Specials exist to prove the show's comedy doesn't need a full episode to land, just two minutes and the right angle on someone's face. The art style carries half the joke before anyone speaks, texture work on expressions doing more than most anime spend entire scenes establishing. These aren't filler pretending to matter, they're the reason you rewatched the series in the first place, compressed and uncompromising.
Two comedy specials bundled with the third and fourth Blu-ray and DVD volumes of Asobi Asobase. In the first, the three girls of the Pastime Club run into Hanako Honda's younger brother, Kentarou, while walking home from school. The shy, studious boy tries to slip away from the awkward meeting but gets pulled along for some fun at the park. In the second, Chisato Higuchi wonders aloud which club member is the strongest, and the question turns into a heated arm-wrestling showdown made messier by some dirty tricks.
