Itai means “painful”.

A red-haired anime character holds a gun to his head in a dimly lit room with Japanese signs, then the scene cuts to a white-haired character with a bandaged face and a wide, unsettling grin, who raises his arms in a dramatic pose against a dark background. The sequence alternates between these two characters, showing the red-haired man in a close-up with a serious expression, then a blurry shot of him, and the white-haired character in a dynamic pose with a knife, before returning to the red-haired man in a shadowy, purple-lit environment.
