After three years under construction Academy City’s space elevator, Endymion, is finally finished. Meanwhile, Toma and Index have befriended the up-and-coming street performer and internet sensation Arisa, who’s just gotten her big breakthrough – the chance to perform a concert as part of Endymion’s grand opening.
Unfortunately for Toma, his perpetual bad luck is still holding steady, because Arisa is more than she seems. Not only are her songs rumored to bring good luck, she has no memories from before the ‘Miracle of 88’ three years ago, when a spaceplane crash-landed in Academy City but all 88 people on board supposedly survived. The forces of both magic and science have taken an interest in her, while Ladylee Tangleroad, the mysteriously young CEO of the company that built Endymion, seems to have ambitions all her own, and it all might be connected to that miraculous incident from three years ago. As everyone prepares for Arisa’s concert, it soon starts to look like the fate of Academy City, and possibly the world, is at stake. Magic and science are about to collide – IN SPACE!
