Toaru Majutsu no Index Light Novel Volume 09/Chapter 3

Part 3
With Stiyl recovering from being hit by Oriana's counterspell, Tsuchimikado and Touma head to the location of Oriana's "Shorthand": in the middle of the "Ball Tossing Contest". They sneak in the event and discover that their opponent would be Tokiwadai Middle School, led by none other than Misaka Mikoto. A chaotic search for Oriana's trap begins in the middle of the Ball Tossing Event.

Part 4
Touma manages to find the trap Oriana laid on the field and protects Mikoto from tripping it, but he found out that it was not the one they were looking for. Instead, there was someone else who activated Oriana's trap: Fukiyose Seiri, who faints instantly after contact with Oriana's spell card.

Between the Lines
Seiri would later find herself waking up in a certain hospital. She was surprised to find herself in the hospital despite her preparations, but later becomes responsible for her current status.
