Summary
Touma, index and Stiyl are sent to 'rescue' Orsulas Aquinas from the Amakusa church who kidnapped her and stole the 'Book of Law', a combination that could upset the whole balance of the Magic side. Needless to say, it's all a ploy by Roman Catholic Church to silence Aquinas since what she knows is too dangerous, and the RCC is willing to screw over members of Necessarius and Academy City to get the job done. In the end it turned out to be a fake interpretation that the author of the Book of Law (Aleister Crowley) putted in, among the other many hundreds there are, and after the fight's over Laura Stuart recruited Aquinas into the English Anglican Church. Stiyl suspects there's some sort of motive behind that move of Laura's, but couldn't figure it out, since to him, "there's no benefit like obtaining someone as powerful as a saint through this deed, unlike taking in the Amakusa church". Later novels suggests Laura did this to get leverage on Kamijou Touma, by taking in friends and allies of his into Necessarius so he'll be more willing to work with/for her if events require his help.(credits: The Observer from OM)
