Cult of Science

The Cult of Science (科学崇拝) is a small and bizarre cult that was formed inside Academy City, belonging to neither magic side nor the science side of the Index universe and apparently is bent on investigating as much as possible about supernatural forces regardless of what side they belong to.

Background
They have shown absolutely no true knowledge about either "Magic" or "Espers" nor even "Hard Science", due to their lack of knowledge they are sometimes treated with mockery by those who truly hold a grasp of the powers they pursue.

Deep Blood Arc
This is their first mention on the series, where it is revealed that they are the financing and administrative power behind the Misawa Cram School before Aureolus Izzard took over the building; they are also the ones responsible for the imprisonment of Himegami Aisa, who was initially captured roughly a month before the fight with the Alchemist.

Sisters Arc
When Misaka Mikoto broke into the institution that receives data from the Tree Diagram, she found in the installation traces of a report directed towards the "Science Worship", that detailed the current condition of the Orihime I.
