Origami Tobiichi | Catgirl with a twist

Origami Tobiichi is one of the main female characters of the Date A Live series. She is Shido Itsuka's classmate, who is famous for her top grades, athleticism, and beauty. She is also a Wizard of the AST, determined to avenge her parents by killing Spirits, but later becomes the eighth Spirit to appear in the series.

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.

After being transformed into a Spirit by Phantom, she realizes that Phantom is the Spirit that made Kotori into a Spirit. She concludes that Phantom probably killed her parents on the same day and travels to the past with the help of Kurumi Tokisaki to save them. She attacked Phantom soon after but finds out that their battle caused the attack that killed her parents. She then realized that the enemy who killed her parents was herself all along. The realization pushed her into the abyss of despair, creating the negative emotions that caused her to inverse as the time-traveling ended.

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. After becoming a Spirit, the color of her eyes turned from blue to light blue and white. In the new timeline, Origami is initially shown with much longer hair reaching down to her waist, before cutting it back down to its usual length after having her Spirit powers sealed. 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. 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. When equipped with her DEM CR-Unit , she wears dark-grey armor with X-shaped thrusters behind her back, displaying an overall thematic design that indicates resemblance to Ellen's CR-Unit .

Origami's Astral Dress resembles a wedding dress, reflecting on her childhood dream of wanting to be a cute bride. It is said to look angelic when gazed from a distance. In this form, she wears a golden crown decorated with a white veil. She has a white bow and gem attached to her neck. Additionally, there are gold extensions attached to both her hips and forearms. The edges of her skirt fold together like flower petals, while the tips of her skirt are also gold in color. There is also a distinct, glistening ring worn on the fourth finger of her left hand. When her Limited Astral Dress is combined with her Ratatoskr CR-Unit , she gains armor with a gold and white color scheme while retaining the former outfit's veil and skirt.

In her Inverse Form, her Astral Dress changes to a revealing dark blue mourning dress. She wears a large veil over her head and has jagged markings on her exposed torso and thighs.

Because Shido prevented the deaths of Origami's parents by her Spirit self's hands, Origami never "entrusted" him with her emotions and became an avenger. As such, the new timeline's Origami is a more cheerful girl, even questioning at times if it was right for the AST to try to kill Spirits. She was shown to be quite a bit shyer and more normal than the old Origami when it came to Shido asking her out on a date, where she found herself constantly trying to find the best way to reply to it. Shido observes that her behavior and choice of clothing are much more feminine than her previous timeline self, though he assumes that the latter was also once like this prior to the emotional trauma from her parents' deaths. She also has no idea that she has Spirit powers, which were inherited from the old timeline alongside her memories.

However, while the old timeline's Origami does continue to exist within her, she is suppressed for the sake of her own sanity, due to the catatonic state of mind that version of her is still stuck in. Old Origami manifests often during her date with Shido through rather perverted or stalker-like actions, much to her confusion, embarrassment, and even horror. When she senses Reiryoku, her original self's hatred of Spirits takes over, and she immediately transforms into her Inverse Form. Later, when the new Origami meets the original Origami and fuses with her, it is finally possible for Shido to save her from her unrecoverable state. It is revealed that the old Origami personality had never actually loved Shido, but depended on him, but the new Origami did come to love him on their date.

In Itsuka Disaster, it's speculated that both timelines' personalities have been reconstructed and mixed after being sealed. However, her old timeline's personality is later shown to have taken over as the dominant personality, despite the changes done to history. Nevertheless, the New Timeline personality still lies dormant and can manifest briefly. She can still take over their shared body in key moments like during the finale of the Spirit battle royal and when Mukuro sealed the memories of Shido from her other self. Her new timeline's personality often shows up in ordinary and everyday situations, or when she panics over her actions towards Shido in private. She's also now very concerned about what Shido might think of her, often worrying if her actions towards him will make him believe she's weird.

As of the new timeline, she also possesses debates in her mind represented by an Angel and a Devil that try to decide which action to take. Surprisingly, the Devil is the reasonable one while the Angel tries to make her follow her desires. The Angel is represented by her old timeline's appearance, while the Devil is represented by her new timeline's appearance when she had long hair. Their debates often lead to Origami losing focus towards reality quite often and are a possible explanation for some of her behavior.
