Juuou Mujin no Fafnir

The world has been irrevocably altered by the sudden emergence of dragons, ancient beasts that have driven humanity to the brink of extinction. In the wake of this catastrophe, a new breed of super-powered girls known as "D's" has risen, the only ones capable of wielding the dragon's power against them. Their training ground? An isolated academy where they hone their abilities, preparing for the inevitable clash that will decide humanity's fate. Enter the sole male D, a mysterious amnesiac who suddenly finds himself thrust into this all-female institution. As he navigates the complex social dynamics and intense combat training, he must uncover the truth behind his own past and the dragons' sudden appearance. With the world teetering on the brink, his arrival could be the catalyst for salvation, or the harbinger of utter destruction.
