anime one love

A young man in a school uniform flexes his bicep against a purple sky, followed by a girl with blonde pigtails and a red eye winking, then a boy in a blue uniform extending his hand toward the viewer, then a girl with black hair and a top hat holding a microphone with "OOOHH!" text, then two silhouetted figures dancing in a green-lit digital space, and finally a bright white flash with light streaks.
