A Certain Magical Index Nt, Vol. 5 (Light Novel)

A school festival, a witch, and an uneasy alliance...Hot on the heels of the crisis in Baggage City, Touma Kamijou returns to Academy City to find the entire student population scrambling to finish preparing for the Ichihanaran Festival-a cultural celebration of massive proportions where schools can attract prospective students. Though Kamijou wants nothing more than to reunite with Index and Mikoto and to go back to his everyday routine, his hopes of returning to normalcy are dashed when one of his most powerful foes appears before him. A few shocking revelations later, Kamijou winds up joining forces with Thor, Gremlin's combat specialist, to rescue a woman with mysterious powers from Academy City custody before the rest of Gremlin-and Ollerus's faction-can get their hands on her. But with so many antagonistic parties in the mix, does Kamijou have any chance of avoiding manipulation again?
