Ora Ora

A purple backpack is shown, followed by an explosion outside a building, then a classroom in disarray with students reacting. A pink-haired girl in a school uniform is seen from behind, lifting her skirt while making a distressed face, with repeated onomatopoeic text appearing on screen. The sequence ends with a close-up of two characters with green hair and faces, also displaying onomatopoeic text. The setting is a school environment.
