Kazakiri Hyouka and the Imaginary Number Sector
Sherry appears in Academy City with the intention of attacking a person of importance to either Academy City or the Church in order to cause a conflict, -- and eventually, war-- between the factions. During her assault, she reveals to Touma that she seeks to keep science and magic divided in order to prevent the tragedy that once befell her friend Ellis, who had been sent to the Church from Academy City for an attempt to create a magician-esper hybrid. This attempt went horribly wrong as not only did the esper participants suffer major injuries from magic, but were killed by the Knights of England as the experiment was illegal under the truce between the Science and Magic sides. Blaming both sides for letting Ellis suffer and be killed, Sherry swore revenge against them by making them suffer like she had. The incompatibility of science and magic destroyed Ellis, and Sherry believed that it was impossible to reconcile the two forces and that it would only result in terrible pain for others. After the events of Volume 6, she has later come to her senses and is shown to hang around Kaori and some of her friends from other branches of the church.
