Origami Tobiichi is one of the main heroines in Date A Live series. She is also a protagonist of Date AST Like, a spin-off manga which focuses on her relationship with Mikie in the AST, as well as the main character of Date A Origami, a 4-koma comic strip manga which focuses on the romantic comedy aspect of the main series.

Origami is a top student in her school both in terms of academics and sports. Of course, none of the student body and facility members know that she is a member of the AST with a few exceptions unknown to her. Origami is a very skilled wizard but can lose herself in her emotions when it comes to dealing with Spirits in combat. Origami is in love with Shidouu, her love for Shidouu is greatly high that she stalks him.

Origami met Shidouu 5 years ago when the first great spacequake happened. Although Shidouu doesn't remember it due to his memories being erased by a certain Spirit.

Origami has a great hatred towards Spirits; 5 years ago when the first great spacequake happened, her parents died due to a Flame Spirit (not Kotori) appearing. causing the whole city to burn and fall.

At the end of Volume 3 Origami saw the Flame Spirit (which was Kotori Itsuka) she assumed that she was the Spirit that killed her parents. On Volume 4 though, that assumption was cleared by Shidouu saying that there was another Spirit lingering at the time the incident 5 years ago occurred.
In volume 10, she was turned into a spirit by Phantom. It's revealed in volume 10 that she went to the past with the help of Kurumi to save her parents. She attacked Phantom who at the time she believed was the one who killed her parents. This proved incorrect when she saw her own attack hit and destroy her parents. She then put two and two together and realized she was her own enemy all along, thus causing great grief and making her go inverse when the time traveling ended.

Origami is shown as a young female with short, silvery-white hair arranged in a bob cut with three hair-clips in the left part of her hair. She has blue eyes and wears the girl uniform like her female classmates when at school.

However, in her AST Combat Wiring Suit, her appearance is more fierce. Origami's clips are not worn, instead a pair of sensors are attached to her hair with armor covering her from shoulder to hand as well as part of her body and legs but not thighs. Her chest is seen at the top of the transparent suit as well as revealing her belly.

Origami is a person that rarely openly talks with other people unless needed with only a few exceptions such as Shidou Itsuka and Tooka Yatogami. She isn't a shy person, but more of an unsocial type of person. She can be a bit reckless or aggressive if she has a goal or purpose to fulfill.

As the series progressed, Origami has shown a growing desire to obtain power. This eventually caused her to join DEM, and later, after she was defeated, to accept a sephira crystal that turned her into a Spirit.

Although disgusted that she became what she had always despised, Origami seemed satisfied that she finally gained the power to fight evenly against Spirits.
As a wizard, She was the vanguard and current "Ace" for the AST. Her skills as a member of the AST were noted to be quite phenomenal, as she was the only one who at first could manage to fight a spirit close quarters(although she still lost), and she was also the most extreme, hoping to kill Yoshino by first dropping a building on her dome. She managed to utilise the CR-Unit , which is noted to be very dangerous and dificult to handle, in fact, no one else but her has proven to be capable of using it long enough to actually put it to practical use. She was even able to land a hit on the world's most powerful Wizard, Ellen, which Ellen herself considers worthy of praise.Finally, using she was capable of destroying a satellite bomb alone, a task which previously took Shidou and multiple (most of them sealed and one injured) spirits' their combined powers to destroy. Likewise, she was able to pressure the (Sealed) spirits into a corner with this unit, but ultimately she was still no match for Tooka when her powers were unsealed.

As a Spirit, Origami is able to fight on par with Tooka at full strength despite the AST's spirit mana detector calculating that her spirit mana was slightly weaker than Tooka's. Origami's spirit powers appear to be of long range type, attacking her enemies from a distance with lasers of shining light and creating some distance between them when they get too close. She has also shown the ability to fly.

Her Angel is a set of golden pillars that surround her and, when put together, resembles a large crown. The pillars can shoot out lasers of shining light from their tips which have proven strong enough to pierce Tooka's Astral Dress when she does not create a barrier around herself. Tooka has also claimed that even if she does create a barrier around herself the lasers would still be able to pierce through. The various pillars can also take on various formations and each of these formations have shown special abilities.

So far, Metatron has displayed the following formations:
- Shemesh - the Sun: The floating pillars spin around her, gathering light particles in which she can release as a rain of energy blasts.
- Mal'akh - Heavenly Wings: By taking on a wing-like formation and folding the pillars behind her back, Origami is able to fly and achieve great speeds.
- Kadour - Sword of Light: By breaking formation, the pillars can each attack its target(s) individually, making it look as if they have a will of their own.
- Artelif - Gun Crown: Her strongest attack; the pillars around her revolve at an incredible speed, creating an energy vortex that shoots pure light energy that can rival Tooka's Final Sword - Halvanhelev.
- Unnamed Defensive Formation: By moving the pillars in front of her, Origami can block incoming attacks.

Finally, Origami has shown the ability to transform herself into light and teleport herself. This (unnamed) ability automatically activates when she is about to be hit by an attack and teleports her to a safe distance. However, the position she is going to be teleported to can be predicted and intercepted. Also, after teleporting herself she cannot dodge an attack by teleporting again in quick succession. Tooka theorizes that Origami either can't teleport continuously or that she can't teleport away from an attack she cannot see coming beforehand.

Origami one-sidedly proclaims herself as Shidou's girlfriend or lover unbeknownst to Shidouu himself. Origami uses any chance she gets to make her relationship with Shidou more intimate. Her love for him is quite unhealthy as she often disregards most of Shidou's feelings or opinions and can come off as self-centered.

In reality, Origami is a stalker with Shidou being the focus of her desires. She has secretly been following Shidou around in his everyday life since before the start of the series and has on many occasions tried seducing him with her actions, such as buying a new bed, making herself deliberately vulnerable, giving him a combination of strong energy drinks and preparing traps to entice him to her. However blunt she may be, Shidou has not acknowledged or reciprocated her feelings.

Origami has also proven to value Shidou's life over her loyalty to AST and DEM, going so far as to steal a dangerous CR-Unit from them and combat them specifically to protect him. She however, does not seem to value his emotions above her revenge, as while she does try to remove him physically from her fights with Kotori and the other spirits, she makes no attempt to stop or even consider his reaction to her killing them. This is especially evident in regards to Kotori, since she is Shidou's sister, while Origami later admitted she didn't want to kill Kotori, and readily believed Shidou when he said that it was a different spirit that killed her parents, it is clear that had Shidou not told her that then she would have without regret.

Origami sees Tooka as an enemy, love rival, and an annoying "baka" that gets in her way with Shidou. Origami shows little respect for her as the quarrel between them as Spirit and AST member remains unsettled despite the fact that Tooka's powers are sealed. Origami does not trust her very much as she views every other Spirit but is not hostile to her due to Tooka's currently sealed status.

In volume 10, it is revealed that Origami actually began to get used to living with Tooka and the other spirits. Enraged by this, she decided to defeat Tooka and the other spirits once and for all and return her life to normal. During the battle, Origami was able to defeat Tooka, Miku, and the Yamai sisters in their limited release Astral Dress. However, just as Origami was about to finish them off, Tooka regained her full power and defeated her. After made Origami a spirit, she obtained many long-range abilities which made her a bad match for Tooka who mostly uses close-range abilities. During the battle between the two spirits, Tooka asked Origami if they could perhaps find a way to understand each other but Origami told her that she will reject all Spirits (despite the fact that she became one herself).
