Ai Mikami

Ai Ikusaba (née Mikami), is one of the Seventh diary owners, which is shared with her boyfriend/husband Marco Ikusaba. Devoted to Ikusaba, Ai and Marco share the "Exchange Diary", which the couple uses to keep an eye on each other at all times. They wish to become Gods so they can be together for all eternity. Ai is a beautiful young woman with shoulder-length dark blue hair and purple eyes; while infiltrating the Omekata religion, she often covers her right eye with her bangs. She normally wears a light blue sleeveless jacket and white pants. From a young age, Ai loved Marco after he befriended her and gave her a family after she was abandoned by her parents as a child (in the anime, she is also grateful for his efforts to prevent her from being sexually assaulted in their high school years). She is very devoted to him, and together they form a strong battle couple. Ai is implied to be a flirtatious person, since the Apprentice Diary she gained, the "Flirting Diary", involved identifying the men she would flirt with. She seems to be at peace with Marco's constant fights, but she is extremely insecure about their relationship; even the vaguest hint of infidelity on Marco's part is enough to send her into hysterics. Marco and Ai share the Exchange Diary, a pair of mobile phones that predict each other's future. Its main advantage is that Ai can predict her own future or Marco's, depending on which phone she uses; however, she generally prefers the latter method so she can protect Marco from danger. While a fearsome combination, the Exchange Diary becomes much less effective if Ai and Marco are separated; additionally, while she would survive unharmed if Marco's phone is destroyed, it would still effectively negate the advantage of her Future Diary.
