"Oldest Living Ootori Faculty Member Tells All" is the oldest of these, written in April 2003, and I suppose could be considered a mutant self-insert story, since Sho-i Tanaka was my nom de plume while writing Shojo Kakumei Ukyo.
"Two for the Road" is a sequel to SKUkyo, and I suppose you could consider it a lame attempt to provide a happy ending for a character that doesn't get one in canon or, sadly enough, in the fanfic that was supposed to provide her with one. Oh well.
"Global Replacement" reflects a change of heart on my part. Originally Blood Red Skies was supposed to be Utena fanfic, but the longer I thought about it, the less the main characters really resembled Juri and Shiori. So, you get the original ending of Blood Red Skies, a severe rupturing of the fourth wall, and a happy ending. Well, two happy endings, if you ask Reiko.
"After The Revolution" is the only "real" Utena fanfic here, which is to say without a crossover. What if Mikage had realized the truth about Mamiya during the final Black Rose duel?
