A female student in a school uniform looks down, then smiles as she reaches out and takes the hand of a male student in a school uniform, who smiles back; the scene cuts to a male student looking shocked as a figure in a restroom stall is struck by a sudden burst of energy. The sequence then shifts to a live-action scene of a band playing, with a male drummer in a black shirt and a female musician in a red top playing a trumpet, all under dim, colored lighting.
