On Kasi's search, she's approached by May. May has been keeping tabs on her and wants to team up to help find her friend. Its her who steers Kasi on the trail of the Cloverpatch.
Why she has an interest in it, May never fully explains. The most Kasi ever gets is that her Father worked with Cloverpatch, and she despises her Father.

Kasi asks why she chose to work with her, beyond her skillset, since she's not exactly trustworthy. May answers that she needed a friend.
