Character

Kotori Itsuka

Kotori Itsuka is Shido's adopted little sister; she is also a middle school student as well as a commander of a secret organization known as <Ratatoskr> that deals with extraordinary beings known as Spirits through peaceful means. Five years prior to the beginning of "Date a Live," the naive young Kotori was tricked by a mysterious being that turned her into a Spirit. Not long afterward, she was told about the method of how to seal her power by the same being that had given her that power. When everything had been carried out successfully, Kotori, whose power had been sealed, and Shido, who seems to have the ability to seal Kotori's power, have their memories of that event suppressed. It was not until the present time, five years later, that Kotori personally uses her Spirit powers to save Shido for the second time in her life; this time from Kurumi when he was battling it out in a sense on his school rooftop. It was not until Shido resealed Kotori's Spirit powers that they finally remembered that event, and soon afterward they later dub the mysterious “being” unofficially with the codename "Phantom." Kotori, being a commander of <Ratatoskr>, knows certain information that only selective <Ratatoskr> members would know.
