Asta - EDIT

A shirtless anime character with spiky hair and a headband stands against a red background, then transforms into a shadowy figure with glowing red eyes, followed by a close-up of a determined face with a red eye, then a dynamic shot of the character with a red eye and fiery energy, then a silhouette of the character with red eyes standing in a forest with a large shadowy creature, and finally the character walking away from the camera through a forest with a dark sky and a red object in the distance.
