Akatsuki and Shiroe were acquainted with each other before the Catastrophe, as they had worked together on quests before. She understood his leadership and strategic skills as well as his experience and time in the game, leading her to seek him out for a potion that could change her appearance (since her avatar was a tall man and it was difficult for her to navigate that body). Since then, she has been his "ninja", devoted to helping her "lord" Shiroe in whatever way she can.
