BOOM

A large, dome-shaped object with a glowing blue light on its surface is shown in close-up, then the view pulls back to reveal it floating above a planet with scattered landmasses, where a bright blue light emanates from the surface. The scene cuts to two anime-style characters, one with blonde hair and a school uniform and the other with white hair, lying on a patterned floor in a dimly lit room, both with wide, startled eyes.
