10월 30일. 제3차 세계대전이 시작된 지 11일이 지났다.

세 명의 소년들은 각자의 생각을 감춘 채 불타오르는 러시아를 달리고 있었다.
전 ‘아이템’의 심부름꾼 하마즈라 시아게는 타키츠보 리코를 치료하기 위해 바쁘게 뛰어다니지만
실마리는 찾을 수가 없다. 열쇠는 전 ‘하느님의 오른쪽 자리’의 성인 아쿠아와의 만남.
최강의 레벨 5(초능력자) 액셀러레이터(일방통행)는
가장 약한 호적수와의 교전을 거쳐 엘리자리나 독립국 동맹으로 이송되었다.
아직 라스트 오더를 구할 방법은 보이지 않는다. 열쇠는 마술이 기록되어 있는 수수께끼의 양피지.
그리고 카미조 토우마는 마침내 피안마와 만나지만,
피안마가 카미조의 사정을 봐 준 데다 카미조는 피안마를 놓치고 만다.
아직 인덱스를 원래대로 되돌릴 수는 없다. 열쇠는 ‘천사’라고 불리는 다른 차원의 존재.
서로 다른 세 사람의 마음을 감추고 과학과 마술이 교차할 때, 이야기는 시작된다―!
