Toaru Majutsu no Index SS: Agnese's Magic Side Work Experience
As the phantom was approaching Calais, he was using the shipping container in which the summoning ceremony was performed when Agnese Sanctis and Lucia burst in to confront the presumed culprit. After the situation was revealed and the other four magicians who had used the container in the past month had been brought to the container yard, he and the others interrogated by Agnese. Answering truthfully about what they were doing, none of them knew the required exorcism procedure as they were not aware of being part of the summoning ceremony to begin with.
