Spheres: Giant spherical unidentified life forms that suddenly appeared in the sky. Their surface is smooth like metal and resistant to external impact. They hover in the air unaffected by gravity, and their internal structure and origin are unknown. Spheres fall from the sky, split, and use tentacle-like attack methods to kill humans, from which they are presumed to absorb energy. They are extremely fast, incredibly numerous, and are divided into small, medium, and large sizes.
