The King of Fighters: Another Day is an animated series based on the popular fighting game series The King of Fighters. It was produced by Production I.G, and revolves around the plot of the 3-D version titled The King of Fighters: Maximum Impact, along with some touches of the current 2-D series storyline about Ash Crimson (e.g. Iori Yagami appearing powerless).

The anime was released in the brand-new ONA format, with four episodes of six minutes each. It was released on DVD as a pack-in with the Japanese release of KOF: Maximum Impact 2. The DVD is region two-encoded, but has English subtitles, as well as an English dub track.

The U.S. marketing strategy of The King of Fighters: Another Day was far less accessible. Originally intended to be included with The King of Fighters 2006 (KOF: Maximum Impact 2's U.S. title) as a pre-order/early buyer bonus for customers of EBGames and GameStop, the U.S. arm of SNK failed to ship out the discs in conjunction with its release. Several weeks later, after some complaint from angry fans, the bonus DVDs started showing up at EBGames and GameStop locations and in many cases were obtainable for previous buyers upon request, yet quantities were limited and many are still left without it despite their devotion.

The U.S. DVD comes in a square cardboard envelope. The DVD is region one encoded and includes both English and Japanese subtitles and audio, both in Stereo and Dolby Digital 5.1. Special features include commentary on all episodes, character design galleries for major characters appearing in the series, one trailer for the animated series and three Japanese commercials for KOF: Maximum Impact 2.
