Christmas in Anime

I am not claiming these are the best Christmas episodes, just to be clear. There are a lot of Christmas episodes of anime*, and I have not nearly watched all of them. Instead, call this a Christmas sampling, in order from 'do not need to have watched any of the series' to 'you will probably be lost without having watched the preceding episodes beforehand'.

( INITIAL D: THIRD STAGE - no really, I swear this is Christmas related. )

( SWORD ARTS ONLINE, ep. 3: Red Nosed Reindeer )

( CARD CAPTOR SAKURA, ep. 35: Sakura's Wonderful Christmas )

( YURI!!! ON ICE, ep. 10: Gotta Supercharge it! Pre-Grand Prix Final Special! )

( POLAR BEAR'S CAFE, ep. 37: Christmas Planning/Christmas Trouble )

*And by 'a lot', I mean 'a search on Google produced at least one master list of Christmas episodes in anime that has 300-odd series listed. And several of those have more than one Christmas episode.'
