Kotori Itsuka

Kotori Itsuka is one of the main characters from the Date A Live anime and manga.

Shido's foster younger sister. Loves her Chupa Chups lollipops. Commander of the Fraxinus. Her personality depends on the ribbons she's wearing: she acts like a perfectly normal girl her age when she's wearing white ribbons, but switches to a dominatrix when she's wearing black ribbons. Nevertheless, she still cares deeply for Shido.

Appearance
Kotori is a cute middle school girl with red eyes and very long, light coral-colored hair that is usually tied on both sides with ribbons in a variety of colors called the twintail hairstyle. She also has an antenna hair that always sticks out on the top of her head.

While wearing white ribbons, Kotori usually wears her school's signature white uniform with a black tie, a short teal-colored skirt, and long black stockings that reach up to half of her thigh. But when she wears black ribbons, her clothes and personality change, as she tends to wear maid-like sleeve clothes, with a black skirt and stockings.

In 'commander mode', Kotori wears black ribbons. To go along with her position as the commander of the Fraxinus, she wears a red coat over a white uniform like a cap, a black tie with red sidelines, a red skirt with white cloth-like sticking out and a pair of long, black boots that reach up to half her thigh. The most noticeable part of Kotori's appearance falls under how she is continuously occupied with a lollipop in her mouth. Her height is stated to be 145 cm in the Anime, and her three sizes are B72/W53/H74.

In her "Spirit form," Kotori wears a white kimono and has a pair of horns sticking out from her ribbons. The ribbons also gain gold flower patterns on them.

Personality
Kotori has three different personalities depending on the situation at hand. As a human, her character changes according to the color of the ribbons she's wearing. While wearing white ribbons or not wearing any, 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. According to Reine, 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 only putting a strong front because the situation requires so.

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. It could be said that fighting strong opponents (and utterly destroying them) is her only interest. She is best described as a sadist when in this state.

In all three cases, Kotori seems to have an 'S' side. Also, her deep feelings for Shido 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.

Spirit Form
Kotori Itsuka was born as a human. However, she received the powers of a Spirit during an incident five years before the main story of the novels started. Nevertheless, the nature of Kotori's powers makes her prone to losing control to destructive impulses over the urge of defeating another Spirit and has caused widespread damage during the two times it was unleashed. For this reason, Kotori sees her Spirit powers as a last resort that she only chooses to use during a desperate situation.

Camael
Angel: Camael (Shakuran Senki (Kamaeru). lit. "Bright Burning Annihilating Demon")

Weapon: Halberd

Astral Dress: Elohim Gibor (Shin'i Reisō: Goban (Erohimu Giboru). lit. "Spirit Dress of God's Authority, Number 5")

Cannon Mode: Megiddo (, Hō (Megido)?. lit. "Cannon")

Kotori's powers are centered on the manipulation of flames that erupt from her body and can be used in close or ranged combat. In her Spirit form, Kotori's clothes change into her Astral Dress Elohim Gibor, which resembles a goddess's robes from Japanese folklore, with a revealing neckline, a translucent sash, and black ribbons tied around a pair of horns. 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 Shido uses/borrows on many occasions when he is trying to make spirits fall for him. Basically, it is an ability that protects the user from certain death as long as the user has enough "mana." It also reverses all physical damage done on the person as if it never happened, but it only covers the recipient's body.
