Kotori

Kotori is one of the main female characters of the Date A Live series. She is your foster sister and secretly works as the commander of the Fraxinus airship. She is considered the fourth Spirit to appear, as her powers were not revealed when she first debuted. Kotori has three different personalities depending on the situation at hand. As a human, her personality changes according to the colour of the ribbons she's wearing: while wearing white ribbons she is that of her "weak self", a delicate little sister who is very dependent upon her big brother; and when wearing black ribbons, she becomes her "strong self", a charismatic and sometimes cynical leader able to successfully command the airship, Fraxinus. the Kotori with white ribbons is the one that can honestly say how she feels, which would mean that the Kotori with black ribbons is simply putting a strong front because the situation requires so. In her spirit form, Kotori acts the same as her ribbons' current color indicates.
