Damn dam dam

A blonde girl with a bow smiles in a dimly lit room, then appears upside down in a hallway with a purple-haired girl, followed by a scene where a girl in a school uniform looks on as another girl pulls down her skirt, then a group of girls in white dresses stand in a circle around a glowing box, then a girl with a yellow ponytail watches two people in a rowboat on a lake, and finally, four girls in maid outfits stand in a room with one girl gesturing.
