Itsuka Kotori

Code name: "Efreet"
Angel: Camael
Astral Dress: Elohim Gibor

Kotori is Shido's foster sister and the head commander of Ratatoskr.
Kotori's character changes according to the color 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. In her Spirit form, Kotori acts the same as her ribbons' current color indicates. But if she stays in her spirit form for too long, her third, "Spirit personality," takes over and she becomes an aggressive and merciless killing machine, who only cares about battling enemies to death.

In all three cases, Kotori seems to have a sadistic side. Her deep feelings for Shidou are always present, regardless of her current personality and help her remember who she truly is. No matter what the situation is, she will always be Shido's little sister.

Kotori is a Fire Spirit and she became one 5 years prior to the main events after being turned into one by Phantom. Her powers are centered on the manipulation of flames that erupt from her body and can be used in close or ranged combat. Her angel Camael comes in the form of a large red halberd but can be dismantled into Megiddo, a cannon powered by Kotori's own flames. Megiddo fires powerful energy beams that can overwhelm even the defenses of other Spirits. Kotori also has a powerful regeneration ability, which Shidou uses/borrows on many occasions when he is trying to make spirits fall for him.
