The official website for the Ragna Crimson anime has announced that the series is scheduled to premiere in Japan on September 30, 2023. Sentai Filmworks had previously announced that it had acquired the license for the anime.

Ragna Crimson is described as:

Dragons reign terror over the earth, sea and sky. If sworn dragon hunters like Ragna are to have any hope of dealing death to these seemingly invincible, fire-breathing beasts, they must find a way to level the odds. Ragna teams up with a mysterious man named Crimson who has likewise sworn to stand against the dragons menacing the world. But although Crimson’s motivations may be mysterious, his goal and Ragna’s perfectly align, and together they’ll fight to vanquish the dragons once and for all.
