This is technically a Mai HIME story, as it's actually set in the Mai Hime canon. Following up on the teaser ending in Mai Hime were we saw Arika in the background, this mini-episode features her in Fuka Academy. A very sweet, very cute episode that implies there is a link between the Hime and Otome worlds. Saying anything else would be a spoiler. While I wish this had been regularly animated, I thought it was very enjoyable.
