Word of Dante: Chaos Card Captor Renae, a currently unpublished but eluded spinoff by one of Chaos Card Captor Sakura’s readers. A great deal of canon is bent, twisted, or just plain broken (for instance, both Lycan and Damien are killed by the end of the fic), but any inconsistencies can be handwaved by Chaos Card Captor Sakura being just one part of a Massive Multiplayer Crossover. Also, Chaos Card Captor Renae hasn’t even been written yet, so the author of that fic will probably take the final revelations into account before writing.
