Date A Live AU | Reincarnated as Shido

Kotori Itsuka is Shido's foster little sister; she is also a middle school student as well as a commander of a secret organization known as that deals with extraordinary beings known as Spirits through peaceful means.

Kotori, being a commander of , is allowed access to certain information that only selective members would know. For instance, Kotori is the only one aware that has prepared a kill satellite for the worst-case scenario if Shido ever lost control of his powers.

Kotori is a cute girl with red eyes and very long, light coral-colored hair that is usually tied on both sides with colorful ribbons in a twintails hairstyle. She also has an Anime antenna hair (アホ毛, ahoge?) that always sticks out on the top of her head. Usually, she can be seen with her favorite Chupa Chups lollipop stick hanging from her mouth. She is 145 cm, and her three sizes are B72/W53/H74.

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 halfway up to her thighs. Her uniform comes with a pocket protector that has a pen with a squirrel head on its cap. Her coat is usually draped over her shoulders, but she does wear it properly during formal meetings with Woodman. After the events of Tohka Good End, she begins wearing both her white and black ribbon at the same time.

Kotori's Astral Dress is a white kimono resembling a goddess's robes from Japanese folklore, with a revealing neckline, a translucent sash, and her black ribbons tied around a pair of oni-like horns, leaving her hair to fall freely. The ribbons also gain decorative golden flower patterns.

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 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 domineering leader able to successfully command the airship, Fraxinus. The personalities are considered “little sister mode” and “commander mode” respectively. According to Reine, the Kotori with white ribbons is the one who 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 all three cases, Kotori seems to have a sadistic 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.

Origami is a top student in her school in terms of academics and sports. Of course, with a few exceptions, none of the student body and facility members know that she is a member of the AST. Origami is a very skilled Wizard but can lose herself in her emotions when confronting Spirits in combat.

Origami is romantically interested in Shido. Her devotion towards him causes her to develop stalking habits such as sniffing his gym clothes. Shido is also the only person not related to any military institutions who knows that Origami is part of the AST.

Origami has the look of a young, attractive female with blue eyes, and short, silvery-white hair arranged in a bob cut with three hair-clips in the right part of her hair. Her facial features are often compared to a doll for both their beauty and lack of expression. She usually wears the Raizen High girl uniform like her female classmates when at school. By the time she settles into life as an university student, her hair has grown to around shoulder length.[12] Origami's height is stated to be 152cm, and her three sizes are B75/W55/H79.

In her AST Wiring Suit, Origami's appearance is more fierce. She does not wear her hair clips; instead, a pair of sensors are attached to her hair with armor covering her from her shoulders to her hands, as well as a part of her body and legs except for her thighs. Her chest is visible at the top of the transparent suit that reveals her belly.

Origami is a person that rarely openly talks with other people unless needed with only a few exceptions such as Shido Itsuka and Tohka Yatogami. She isn't a shy person, but more of an unsocial type of girl that speaks with a blunt and forward tone. As such, she has virtually no shame in displaying extreme lust toward Shido even during public scenarios.

She can be a bit reckless or aggressive if she has a goal or purpose to fulfill; she's also willing to do something that someone else wouldn't do to accomplish such goals. This determination is shown when she did everything Shido asked her when he was trying to get her to not like him which shocked everyone around her.

Due to a Spirit killing her parents five years ago, Origami has harbored an intense hatred and hostility towards all Spirits, as whenever she sees a Spirit, she loses all of her common sense and tries to kill it any way she possibly can. She has a stronger drive to defeat them than her AST comrades, viewing it as both revenge and protecting other people from potentially suffering the same loss she experienced.

Tohka is a girl with very long, dark purple hair in the same shade as the color of the night. She partially ties it back into a ponytail with a ribbon while still letting much of her hair fall to her knees. Her dark purple eyes are described as crystal-like and have a golden tint. Shido remarks that her beauty is to the extent of almost being violent. Tohka's height is stated to be 155cm, and her three sizes are B84/W58/H83.

Upon her arrival on Earth, Tohka wore an Astral Dress with a black, cream, and pink color scheme and a set of purple-and-cream plated armor that adorned her shoulders and waist. The dress is open at the back and made up into a black corset (which exposes a part of her cleavage) and a two-layered, knee-length skirt that has a pink-and-white gradient. Her hair is tied back using a butterfly-shaped hair accessory. She also wears a pair of gauntlets which have petal-like cuffs, both sharing the same color scheme as her attire, as well as a pair of armored boots. While using Halvanhelev, her ribbon grows longer and sharper, and her underlying dress of light becomes more ragged.

When Tohka first appeared on Earth, she had a cold and emotionless demeanor. She was very wary of humans, as her only experience with them was being constantly attacked by the AST before Shido finally got the chance to talk to her. However, once her first date with Shido allowed her to experience human society, she grew to admire the world and even sympathized with the AST for wanting to eliminate her for the destruction she unintentionally caused via Spacequakes. After her sealing, she could finally develop and express emotions by experiencing life on Earth. Since everything is new to Tohka (including her own emotions), she has a very cheerful and child-like personality that can make her seem naïve, emotional, energetic, and gullible at times. She easily became excited at seeing all the things on Earth that she had never seen before. Origami has used her naïve nature against her on multiple occasions. In these scenarios, she usually needs one of her friends (usually Shido) to point out she is being deceived. She also has a voracious appetite, with a particular fondness for kinako bread.

Despite her lack of knowledge or experience, Tohka does have a reasonable sense of modesty, as shown by her violently overreacting when Shido caught her in humiliating situations. She did not, however, initially know what a kiss was, nor did she hesitate in performing one for the first time with Shido. However, she later found herself hating having to see him kiss other girls and asked Shido to not do so while unknowingly also giving a mutually exclusive request to continue rescuing Spirits. At times, Tohka can be surprisingly insightful and perceptive in regard to other people's feelings, especially when it concerns Shido and her fellow Spirits. She also initially had difficulty understanding the concept of love, not realizing what her feelings for Shido were until Volume 12.

It has been shown several times that Tohka has a decent level of sensibility and instinct towards the battle, which arguably is the only thing of which she has any real memories. When faced off against Origami, who had only recently been transformed into a Spirit, she was able to analyze Origami's new powers quickly and came up with the best method to counter them. This expertise could also be the result of her constant battles with the AST until she met Shido.

When in agreement with something, Tohka often has a verbal tic of saying "umu" an old-fashioned expression of affirmation. She also has an unusual intonation of long vowels, such as mispronouncing the word date as “Dehto” instead of “Dēto”

Compared to Tohka, Tenka is considerably more hostile than her other self. While Tohka would normally hold back so as not to kill her opponents unless severely angered, Tenka will utilize unrestrained force to eliminate her foes. During Tohka's first Inversion, she also has no remembrance of Tohka's recent memories, namely her memories of Shido, and comes to interpret him as a human trying to deceive her. This paranoia likely stems from Mio trying to kill her seconds after being born.

Tenka also has a haughty demeanor, constantly looking down on humans for being inferior and having pride in her status as a pure Spirit. Tenka often speaks in a rude and informal manner, rarely ever addressing others by name as a likely result of not having one herself for a long time. While more serious than Tohka, her lack of experience with human society also begets a degree of naïveté and gullibility

At times, she is particularly blood-thirsty in combat, relishing a good fight against a worthy opponents.

Sawa Yamauchi is Kurumi's best friend, who later became the Nightmare spirit. Just like the main timeline where Kurumi becomes Nightmare. Sawa becomes Nightmare herself instead of Kurumi.

Sawa was an ordinary high school student. She was close friends with Kurumi Tokisaki, and they often chatted at school.

Sawa looks like a young girl with brown hair in three braids , she has a charming smile with small fangs that sometimes peek through it.

Sawa was a kind-hearted girl that had a special fondness for cats. But now that she's the Nightmare spirit, she no longer has any of her humanity left to show kindness to others.

Like Kurumi, Sawa was drawn into Mio Takamiya's plans. After killing the Fire Spirit, Sawa entrusted the purification of the Sephira Crystal to Mio and went to Kurumi. Determined to invite Mio too, Sawa ran back to Takamiya, where she saw that the Fire Spirit was her friend who had lost her mind. Falling into hysterics, Sawa began to inverse.

Realizing that she had killed by her best friend. Sawa stopped her Inverse transformation, separateding it from her body.

Nia, also known as the Second Spirit, is a Spirit who appeared on Earth sometime after the First Spirit appeared and is claimed to be the only one who knows any information about the First Spirit and her whereabouts. At some point, the DEM captured her by unknown means and she fell into a comatose state.

Nia's location was revealed to be at the Neryl Island, a DEM's private island in the Pacific Ocean. On the island, she was given the label Material A, and was being moved to another place through a DEM transport aircraft.

Nia has short, ash gray hair and turquoise eyes. Nia's Astral Dress takes on the appearance similar to that of a nun. Her Astral Dress is an ink-colored semi-transparent fabric that completely displays her figure. The collar of her dress takes on the shape of a pen tip, and the middle part of her Astral Dress is patterned as a manga panel, both of which referencing her job as a manga artist. She wears long black laced boots and a gray veil with a pen attached. There is also a golden cross connected to a beaded rope surrounding the waist of the dress. Her veil, collar, and cross are all adorned with turquoise gems matching her eye color.

When she is not using her Astral Dress, she wears dark red square-framed glasses. Her casual outfits tend to be relatively unfeminine, only wearing dresses on special occasions. Her three sizes are B76/W59/H80.

Nia has a very energetic personality that allows her to get along with everyone. This cheerful demeanor also helped her readapt to society very quickly alongside the aid of her Angel. This kind of personality was also shown throughout her first date with Shido, where she maintained a playful attitude while teasing him.

However, thanks to her powers, Nia began to lose her ability to open up to humans. Her omniscient Angel ended up backfiring on her after she became curious about her origins. The feeling of distrust started sitting in her heart after she had learned about her past self. Nia also started checking each person she knew and became disgusted with humans after discovering the dark side of humanity through . It ultimately made her distance herself from her acquaintances and ended up leaving her alone. Since she could not live without coming into contact with anyone, Nia decided to put on a mask and treated everyone as if they were NPCs in a game.

Afterward, she began to immerse herself in the 2D world, since it was the only thing she could open her heart to without fear of disappointment. The characters in that world were very straightforward yet sophisticated at the same time. Best of all, they would never betray her since she couldn’t detect any malice from them from using . However, her interactions with Shido proved that she still had hope that she could meet someone whom she can open her heart to, something that Westcott took advantage of substantially.

Nia also has a significant hate towards spoilers. She does not like spoiling something to someone and also hates being spoiled. However, she will disregard this if she is very angry about certain things. During her conversation with Kurumi, Nia also remarked that she did not want to use her powers to start a conflict and would not reveal any dangerous information, even if the other party demanded it from her.

She is also very passionate about her Otaku hobbies, becoming furious after she found out Shido was acting out of character while cosplaying her favorite character, Tokiya, to make her fall for him. Due to this hobby, she often makes up nicknames for the other Spirits. She is a heavy drinker and fills her kitchen with alcohol, which is otherwise empty because she exclusively eats instant food or take-out unless Shido is available to cook.
