Cynthia (or "Cindy") is a Japanese-American teen idol who ran away from home to her mother's homeland because of her dysfunctional relationship with her father, the CEO of IBN. She was attempting to buy the most expensive PC in a computer store in Akihabara ( ¥3,128,000 ) when Hitoshi recommended a simpler model. Choosing Hitoshi as her computing teacher, Cindy flirts with him in front of Saati to the point of an ecchi tug-of-war that knocks him out cold. When they learn that Cindy wants to overcome her acute technophobia in order to write a combined apology/birthday e-mail, both of them help her finish the job, with Saati becoming the "computer fairy" in order to find her father's e-mail address.
