Background
At the start of Misaka Mikoto and Shokuhou Misaki's first year at Tokiwadai Middle School, Mikagami was in her third year and leader of one of Tokiwadai's 'big three' cliques. The Mikagami Clique was apparently made up of students who were mostly drawn to her oil control ability and sought her to fulfill their own desires (such as manipulating fat in their body to enhance their bust or slim them down), with Mikagami only doing this for those who contributed the most to her clique. The clique was in second place and of the three, was said to be working the hardest to get results.

Abilities
Mikagami's esper ability involves oil control (油性操作), being able to manipulate a target's oil content. This includes the manipulation of fat within a human body (e.g. for purposes such as bust enhancement or slimming), which she does for those who have contributed the most to her clique. As a student of Tokiwadai Middle School, it can be presumed to be at Level 3 or 4.
