Vertebreaker

A character with spiky blond hair and a headband is shown in distress, screaming with blood on his face, then transforms into a glowing, blue, fox-like form with multiple tails, followed by a close-up of his face with a determined expression, and finally a shot of a hand with a spiral seal on the palm as a beam of light shoots upward. The sequence takes place in a dark, abstract environment with shifting colors and light effects.
