Mitsuki happy to see Mikey - Mitsuki vanishes.png

Despite playing a tough girl on camera, she has a heart of gold and deeply loves and cares for each of her best friends, despite each of them having their flaws. She had been a spy 5 years prior to the events in the series. Despite her liking for the job, she craved a more normal life and quit, becoming an actress on LilyMu soon afterwards where she, no doubt, continued to use her former spy persona onscreen. During her days as a spy; she, as the red-wigged "Agent M," had missions to recover microfilm and other objects stolen by criminals. She worked for a man trapped in a mailbox costume, codenamed Agent F, and Mitsuki was supposedly the best spy who had ever joined the organization.
