At the opening of the OP, something like a shooting star shoots across the sky. Several girls with wings look at it with awe and begin to follow where it's heading. It gets closer and closer to this large place but is yet to land. Then the view changes to someone looking around at all the girls with wings shakingly. Finally, the shooting star like item floats into a window and burries itself into the floor and then it begins to sprout.
