Blue exorcist

A dark-haired anime character with intense eyes grips a sword hilt, his expression shifting to a determined snarl as he prepares to draw the blade. The scene cuts to a character in a white outfit soaring through a blue sky, then to a bright blue energy burst, followed by a blue energy trail, a clash between two characters with glowing swords, and finally a close-up of a character's face illuminated by blue energy.
