Nagisa

A blue-haired anime character stands shirtless in water, then turns to face two other characters, one with brown hair and one with blonde hair, as the scene cuts to a close-up of a different character's face with the word "internet" overlaid. The sequence continues with a static image of a blue-haired female character in a black top and red plaid skirt, followed by a similar image with a smaller red-haired character appearing in the corner.
