A new trailer offers a two full minute look at the A Certain Magical Index movie. The Miracle of Endymion anime feature, which boasts a story from author Kazuma Kamachi and designs from illustrator Kiyotaka Haimura, is slated to hit Japanese theaters February 23, 2013.
Yōko Hikasa (Nobara Yukinokōji from Inu x Boku SS, Sera from Kore wa Zombie Desu ka?), Ayane Sakura (Joshiraku's Marii Buratei) and Sachika Misawa (Accel World's Kuroyukihime) have signed on to play original roles.
Hiroshi Nishikiori is as returning to direct the J.C. Staff production with a script by Hiroyuki Yoshino (Macross F, Accel World).
The primary original character is Arisa Nago, a Level 0 (person with no powers) girl who Index and Kamijou meet at the outset of the movie, and is subsequently revealed to be targeted by Stiyl Magnus and his team of magicians.
Toaru Majutsu no Index wikia, describes the plot:
Academy City’s space elevator Endymion. One day as its completion nears, Touma and Index meet a Level 0 girl named Nago Arisa. Index and Arisa have a mysterious connection in their ravenous appetites. While the three are enjoying their time afterschool, 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 form the magic side underway, Academy City deploys a unit meant to maintain order led by its female leader Shutaura. As the situation developing around Touma, 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!
