The Dragon-Commanding Daughter Rises

DramaWave released it as 40 bite-size episodes mixing fantasy, made to watch on a phone in one sitting or a few.

The draw here is a world with its own rules and a lead who learns to bend them.

At about 48–88 minutes in total, it's quicker to finish than most full-length series.

Start from episode 1 below; autoplay takes you to the next episode when one ends, and nothing needs a sign-up.
