Niko

A young girl with black pigtails and a green bow performs a series of cheerful poses, making a heart shape with her hands, saluting, and forming rock signs with both hands while smiling brightly. She is indoors, in front of a window with red curtains, and the sequence is accompanied by on-screen text that reads "Nico-nico Smile!" and "Yazawa Nico-nico gave you a smile!".
