Ai Yori Aoshi's Christmas episode is an oddity, since it isn't a part of the series' canon. The episode takes a slightly different route by setting the characters into a time point before the original Ai Yori Aoshi. After a long night of work, Kaoru encounters a strange twist of fate when he is assaulted by a flying necklace. It isn't long before Kaoru finds the necklace's owner, since she appears in Kaoru's apartment shortly after Kaoru collapses on his futon. The mystery girl introduces herself as Santa Claus... well, a Santa Claus. The necklace is the key to Santa's home world, and she cannot return without it.

As a way of thanking Kaoru, Santa grants Kaoru one wish. Kaoru obviously wishes to spend Christmas with the sexy Santa. Of course, sharing Christmas with a Santa that would make most supermodels blush is awkward enough. Kaoru asks the lass for another name. Santa obviously has none, since Santa is Santa. Kaoru quickly decides a new name for her: Aoi. The rest of the episode focuses on Aoi and Kaoru's special Christmas encounter, in true AiAo fashion. There are plenty of goofy moments, accompanied by points that are best described as "bittersweet." All of the major characters, from Mayu to Miyabi make an appearance. On top of all of that, Aoi appears in a skimpy Santa suit! What more could an AiAo fan ask for on Christmas morn?
