Itachi

A young ninja with dark hair and a headband stands in a dark, watery environment, holding a sword with a glowing blue energy effect. The sequence shows a close-up of his wide eyes, a view of his hand gripping the sword, a full shot of him in a defensive stance with other figures in the background, a close-up of a smiling seal-like creature, and finally a shot of him looking up with determination against a cloudy, green-tinged sky.
