Rachel could hardly believe her luck she had been chosen to be a part of the Bureau of Supernatural Affairs. For months people had argued whether or not supernaturals she be a part of the agency or not. many thought that supernaturals would be more sympatric and unable to enforce the laws when it came to other supernaturals. Personally Rachel thought that would be like saying that humans couldn't supervise their own kind which they have been doing for centuries. As she walked to her very first official meeting she looked at how she had come to be part of the agency.
When she had heard that the MIB was thinking of expanding to include a branch that focused on supernatural crime she knew she had to try for it. She always wanted to do something important. Something that would help people. When it was decided that the BSA, as the agents called it, would included supernaturals as we well as human they indicated that they would start by given one member of each species a chance to past the tests. As far as Rachel she was the only which that tried. Which is probably why she passed even though her magic wasn't always reliable.
