Are there any somewhat heavy fast paced medieval or action based yuri? (bonus if it includes fantasy aspects)
First things coming up to my mind are "Do You Think Someone Like You Could Defeat the Demon Lord?" (adapted from the light novel with the same name) and "The Executioner And Her Way of Life" (this one will get an anime adaptation). I don't know if that's what you're looking for but they are fun to read (the light novels are pretty good too).
