Stick 'em!

Three anime girls in school uniforms stand together, raising their arms in unison with joyful expressions, then the scene cuts to one girl with a shocked face as another collapses behind her with a lightning bolt effect. The sequence continues with two girls in a chibi style looking at a tablet, then a girl in a pink shirt reacting in surprise to another girl in a school uniform in a bedroom, followed by a girl in a school uniform running through a living room and then falling forward onto a table.
