   The first book: Sans's magical power is too abundant, requiring him to take medication, but he accidentally enters the universe's destiny. The fifth book: Killer and Undyne enter the universe's destiny, including revelations about their past and the leader of the Bones gang coming to find them. The sixth book: The protagonist becomes one with all the Sanses and travels to many worlds. The seventh book: All three Bones of the Bones gang achieve enlightenment. The ninth book: He discovers that this world is made of data, so he travels to other universes to help the Sanses there. The tenth book: Sans suffers experiments from Gaster, and after his universe is destroyed, he does the same thing as Cross, but is quickly returned to his own universe, and then the story ends.
