Typically, an anime will last for a single season, which is usually 12 or 13 episodes. While these shows can be watched in relatively short order, most of them are arguably better experienced over multiple days or even months if they are watched as part of a seasonal lineup. Sometimes, a series comes along that is so successful that it receives multiple sequels or, seemingly, refuses to end, producing hundreds of episodes in the process. Also, occasionally, a short anime comes along that tells a full and satisfying story in less time than usual.
