When a bonus episode is included with the DVD release of a series, beyond a simple Omake. With many recent anime series being Twelve-Episode Anime, creators will sometimes add an entirely new 13th episode which may or may not fall into any strict continuity with the rest of the series -- in effect, an intentional Missing Episode. Timing these after true finale episodes can seem awkward, even more so when they use the non-broadcasted aspect to up the Fan Service noticeably. If the 13th episode is part of the original showing instead of a bonus, the group is called a Cour (french for 'a run').
