The woman

A character with blue hair and a white mask on his face makes a hand sign, followed by a close-up of his eye with a red, three-tomoe Sharingan. The scene cuts to a foot stepping on a large, dark, segmented object on a tiled floor, then to an explosion of paper and fire. The sequence ends with a close-up of a hand holding a glowing red eye with three tomoe, set against a bright, hazy background.
