The video opens on a modern cityscape with tall glass buildings under a blue sky, then cuts to a series of close-ups of students in school uniforms. A boy with green hair looks surprised, a boy with spiky blonde hair flexes his arm, a boy with glasses stares seriously, and a boy with red hair grins widely. The sequence ends with a group of students, including one with a rock-like head and another with a bird-like head, reacting with shock as a teacher announces they will take the most units of a subject.
