Academy City's space elevator Endymion. One day as its completion nears, Kamijou Touma and Index Librorum Prohibitorum meet a Level 0 girl named Meigo Arisa. Index and Arisa have a mysterious connection in their ravenous appetites. While the three are enjoying their time after school, Stiyl (who has brought in some other magicians) suddenly attacks. His target is Arisa. Why is a member of the science side like her being targeted by the magic side? With the attack from the magic side underway, Academy City deploys a unit meant to maintain order led by its female leader Shutaura. As the situation developing around Kamijou, Index, and Arisa grows more and more confused, Stiyl says, "That girl could likely cause a war between the magic side and the science side." When science and magic cross paths, the story begins with Endymion as its stage!
