My king

A dark-haired anime character with glowing blue eyes and a black coat wields a glowing blue sword, engaging in a high-speed battle with a large, shadowy creature that has a red eye, amidst bursts of blue and purple energy and debris. The character moves dynamically, striking the creature, which reacts with energy explosions, before the scene cuts to the character's determined face and then a final shot of him standing with his sword raised, surrounded by swirling energy.
