Panic ensues in Academy City upon the arrival of the sorcerer Sherry Cromwell, who makes no secret of her plans to destroy Kazakiri! Kamijo steps up to ruin Sherry’s plot – but the situation is more complex than he knows.

Tōma stops and successfully destroys Sherry's golem with Imagine Breaker. When she summons another one,Tōma coordinates with the Anti-Skills to put her on the defensive. Sherry attempts a simultaneous summoning of Ellis, destroying the ground beneath her and escaping. Wondering why Sherry would turn to escape so quickly when her target, Hyōka, was right in front of her causes Tōma to realize that her true target was Index all along. Chasing after a runaway Sphinx, Index is attacked by Ellis. At first she is able to hold her own against the remote controlled Ellis by interfering with the control mechanism, when Ellis switches to automated control things turn worse. Index can only call Tōma's name as Ellis prepares to crush her.
