A fantasy about an elegant yet rebellious fighter, who doesn't let anyone take advantage of her!! (Source: Alpha Manga)
This is such a fun manga and for some reason nobody picked it up for a physical western release (it is available on some app I’m not downloading). It should make for a great anime and I had somehow completely missed the news that it was getting adapted.
Best news of the day!
