Characters appearing in Date A Live. There will be unmarked spoilers for those who haven't read the light novel.note Also, the online translations may not always be accurate. Cross-check with multiple sources if necessary. If any names have errors, please correct them.
The main protagonist. For some reason he is able to seal a Spirit's powers in his body with a kiss, given that the Spirit holds enough trust or affection towards him. He also has a Healing Factor. Currently adopted by the Itsukas, having been abandoned by his birth mother for unknown reasons. He and Mana are biological siblings. This is confirmed by Isaac Westcott in Volume 7, who called him Takamiya before quickly switching to Itsuka.
Accidental Misnaming: Reine kept getting his name wrong, so she just started calling him Shin instead note Oddly enough, she only calls him by this nickname when talking with him, as she otherwise refers to his actual name when around Tohka. This eventually becomes an In-Series Nickname of sorts for him.
All Your Powers Combined: Later volumes show that he can use the Angels of the Spirits he kisses, the most prominent example being Tohka's Sandalphon. As Volume 7 reveals, he can use multiple ones at the same time.
Because You Were Nice to Me: How Shido generally wins over the spirits. Unlike the AST, he doesn't follow a "shoot first, ask questions later" mentality, and finds that most of them are fairly harmless if not being shot at, such as Yoshino.
Kotori, despite the lack of blood relation, is treated like a real sister, to the point where Shido would believe fake promises, such as her waiting in front of the family restaurant even if there's a spacequake happening. While the reveal of her bossy commander mode put him off for a while, he cares for his little sister.
Because Yoshino has trouble communicating with others without resorting to Yoshinon, Shido takes up the role of becoming her new "hero", and also fosters a big brother relationship with her.
Bishōnen: Comes in handy when he has to crossdress!
Blunt "Yes": Delivers two to Miku, when asked if Tohka was more important to him than his life, and later on, when asked if he would risk his life to save Miku like he would Tohka, should the situation call for it. He delivers on both counts.
Cast from Hit Points / Heroic RROD: When he uses Sandalphon, it really strains his body to breaking point, as his body is not used to it. Unlike most cases, he can counter it with his Healing Factor, though it still hurts really bad.
Shido: So this means…? Should I call Tohka with Yatogami from now on? Somehow I can't get used to that…
Death Is Cheap: He's been on the brunt end of several accidental attacks, both from Spirits and the AST alike, yet he recovers just fine, sometimes too quickly. This is due to Efreet's power being sealed inside him, courtesy of having sealed Kotori five years before the story. For some reason, he's still treated as being killed.
Determinator: In Volume 7, after Tohka was captured by Ellen and Westcott, he vows to save her, then proceeds to head straight to the DEM building. It doesn't matter if you stab him or pierce his chest; he just won't stop.
The Dulcinea Effect: He's very strongly affected by this, wanting to help the girls that he just met and blew up a large portion of town. The Ratatoskr backs him up in his efforts as well. To wit:
In the anime, when he tells Yoshino he'll be her hero:
Shido (thinking to himself): That's right. It doesn't matter if she's a Spirit. There's no way I'm leaving this sweet little girl to fend for herself!
Wanting to save Kurumi, who had killed over 10000 people with her own hands, with Shido himself as her next target? Check.
Trying to resolve the conflict between Kaguya and Yuzuru Yamai, whom he just met at the beach and can't stand seeing one of them die for the other? Why, Take a Third Option, of course!
Harem Seeker: A rare case of the Harem Seekernot wanting his harem. He's only dating the Spirits, to, well, save the world, as put by Kotori, and from the start he didn't want to be have to talk to them by dating them, insisting that there is another way. Kotori shoots down his arguments, of course.
His promise to Tohka not to kiss any other girl, on the other hand, just can't be kept, because it's what's needed to seal a Spirit's power. Though Tohka being Tohka may have forgotten about it already.
Impaled with Extreme Prejudice: During Tohka's Rescue Arc, Shido is able to get all the way to highest level of DEM's headquarters, where Tohka is held captive. But then, Ellen stabs him from behind, and would have killed him had she not been interrupted by Tohka's sudden transformation into her Inverse Form.
Indirect Kiss: Kurumi and Shidou share one in the Date-A-Live Drama CD, when Shidou gives Kurumi some of the drink he's already had. Kurumi takes note of it.
Insistent Terminology: Most of the people who see his latent powers in action during the latter volumes suspect he's a Spirit; in truth, he's a human who can use Spirit powers, at least for now.
Laser-Guided Amnesia: He has the most holes in his memory out of all the cast. (Tohka doesn't count; her memory is literally one big hole.)
Leeroy Jenkins: His method of rescuing Tohka? Just rush into the DEM building (where Tohka was being held captive) and try to find her. If not for Miku's assistance and his regenerative powers, he would've been screwed.
Living Emotional Crutch: He is this for Tokha, as well as Origami. Westcott plans on letting Shido grow closer to the Spirits he sealed so that he becomes their crutches as well. Then kill him, causing them all to Inverse.
Mistaken for Gay: Twice, no thanks to Natsumi taking on his appearance and screwing around with the rest of the class.
Oh, Crap: When he sees Tohka see him about to kiss Yoshino for the second time. And he was just trying to demostrate what he accidentally did to her the first time! Of course, this is just asking for trouble...
Parental Abandonment: His mother abandoned him, his father isn't mentioned, and his foster parents are both working overseas.
Power Parasite: He seals Spirits' powers within himself by kissing them.
Real Men Wear Pink: Has great make-up skills due to his training as Shiori. He also is a great cook and finds the task enjoyable.
He screams Tohka's name while he's falling down from the Fraxinus. This is after he finds out that he has a Healing Factor.
In a Call Back to Volume 1, Volume 7 does almost the same thing, only instead he's falling from a height the Yamai twins brought him up to. Also, just before this, he shouted out Miku's name as he moved to shield her from Tohka's attack.
Take a Third Option: Shidou states he cannot stand only having two options; he's always worked with more than one. When he's limited to two, he will force a third option. Just ask the Yamai twins, who Shidou saved by forcing them both to live.
Taking the Bullet: For Tohka in Volume 1. He would have done this for Kurumi in Volume 4, but Kotori shifted her aim in time. And does it again in volume 11 when he pushes Origami's parents out of the way from one of Origami's missed attacks at Phantom.
The Game Come to Life: In Arusu Install, after trying out a new game by Ratatoskr, the game shuts down but the simulator still runs, trapping Shido in the game world.
Traumatic Superpower Awakening: In episode 4 of season 2, after Tohka suffers a defeat in battle, Shido is once again helpless as he watches the Bandersnatch drones attempting to carry her away. He thinks to himself that he never wants to be unable to protect anyone again, having failed to do so many times before. Then suddenly Sandalphon, Tohka's sword, appears in his hand, and slices a couple of the bandersnatches. He also uses her sword to break up the fight between Kaguya and Yuzuru.
Took a Level in Badass: Given that he can use the powers of the Spirits he kisses, for each Spirit's powers he seals he takes one Level in Badass.
Wholesome Crossdresser: In Volume 6 / second half of the anime's 2nd season, he has to dress up as "Shiori" in order to get close to Miku unsuspected. Tohka however sees through it and Origami takes a lot of pictures. Kurumi also sees through it, and teases him for it hard.
Badass Adorable: They're, simply put, cute girls with superpowers ranging from control over elements to reality-warping concepts such as Time Travel. And regular humans rarely have a chance to even stand up against them, unless they're an enhanced Super Soldier like Ellen.
Badass Crew: Volume 9 has Shido's harem work together to destroy two satellites targeted at Isaac Westcott, right above the city.
Fire-Forged Friends: They all become friends despite causing a lot of trouble for the setting. When a new Spirit appears, the girls are usually happy to meet them, as Natsumi finds out despite her misgivings.
Friendless Background: Goes with the whole "hunted just for existing" thing. The Spirits dealt with it in various ways. The Yamai twins are relatively well adjusted in this regard, as they had each other.
Kicking Ass in All Her Finery: Save for Yoshino and the Yamai twins, the Spirits' Astral Dresses are elegant and stylish robes, and they wear it during most of their appearances, which often includes fighting against the AST / DEM.
Laser-Guided Amnesia: The Spirits who weren't humans turned to Spirits, anyway know nothing of the dimension they apparently come from.
My Suit Is Also Super: Their Astral Dresses also have some degree of protection, being part of their powers, though the dress itself pales in comparison to what they can do. Miku's in particular can give off light; useful in the case of lights failing to work during her concerts.
Nigh Invulnerable / Person of Mass Destruction: Due to their Angels, not only are they impervious to nearly everything the AST throws at them, but they also bring out the pain in spades, usually causing environmental destruction.
Power Incontinence: By virtue of involuntarily causing spacequakes whenever they come to this world. They can also voluntarily cause them, as Kurumi, Kotori and Miku have shown. On top of that, some Spirits with powers related to the weather cause changes (like rain for Yoshino or storms for Yamai).
The Spirits Shido seals the powers of will undergo this as well by virtue of their power flowing back into them, if their mental state becomes unstable. The worst possible situation is when a Spirit crosses the Despair Event Horizon, turning into their Inverse Form and rampaging indiscriminately.
Religious and Mythological Theme Naming: Their Angels are named after the Archangels of their respective Sephirot of the Kabbalah Tree of Life, based on the numerical kanji in their namesnote Raphael and Michael represent the 6th and 8th Sephirot together, so it's technically not wrong for Yamai's (8) Angel to be Raphael. Their Astral Dresses are named after the Divine Names of said Sephirot.
Transformation Sequence: Both played straight and inverted. Spirits can turn their Astral Dress into normal clothing and back via this. It's mentioned that there is less protective value in that mode, and all the Spirits seem to revert to their normal Astral Dress for combat. Or as much of their clothing as they can, anyway. The length of each Transformation Sequence varies. The first time we see this is Tohka changing her Astral Dress into a school uniform for her date with Shido.
Unskilled, but Strong: Most of the Spirits take advantage of their vast powers to do the fighting, and don't generally resort to any kind of tactics. Despite this, they can easily get caught off-guard by those they can't defeat outright, such as Ellen.
The first Spirit that Shido encounters. Shido named her Tohka after the date of their first meeting (April 10), with one kanji being different. Reine later added the Yatogami surname. Shido seals her powers at the end of Volume 1, and she is allowed to attend the same school as him.
Adorkable: Her utter sincerity about everything and her innocence is very endearing.
Aloof Dark-Haired Girl: Before she went on a date with Shido, she was initially hostile to him and practically refuted all attempts to communicate with him, which was not helped by the AST's attacks on her.
Badass in Distress/Damsel in Distress: She gets captured by the DEM at the end of volume 6, and volume 7 is dedicated to Shido trying to rescue her. He does, but not before witnessing just how powerful Tohka's Inverse Form is, prompting him to kiss her again and end her rampage.
Because You Were Nice to Me: Shido manages to survive against Tohka early on because he was the first person that didn't want to instantly shoot her.
Berserk Button: If Shido lets her see him kiss another girl... he'd better watch out. And woe betide anyone who dares hurt him in front of her, or just simply threaten to. Ellen learns this the hard way in volume 7.
BFS: Her Angel, Sandalphon, is a massive broadsword which is summoned from a throne. By fusing said throne with the sword, she can transform Sandalphon into the Final Sword, Halvanhelev, which is an even bigger blade decorated in gold and black colours, with red Tron Lines. Her Superpowered Evil Side wields a dark version of Sandalphon, called Nehemah, and can similarly reform her blade into the Final Sword, Paverschlev.
Clingy Jealous Girl: Towards Shido. In episode 12, she tells him to keep helping Spirits in need, but to not kiss them. When he explains that it would make helping them difficult, she tells him that she doesn't like seeing him kiss other girls. So naturally after he seals the Yamai twins, they make it sound like he did something perverted to them, only further angering Tohka.
Contralto of Danger: She had a relatively low voice pitch when Shido first encountered her while she was fighting the AST (lower than the rest of the Spirits, in fact). This changes once she is sealed, though, and her tone becomes lighter. It's played straight again when she taps into her Inverse Form, reverting to situation similar to the very start of the series.
Fish out of Water: Initially. She thought the world was an uninhabited wasteland only populated by flying mecha troops that would ineffectually try to kill her. Of course, even now there's still a lot of things she has to learn about this world...
Forced to Watch: When Westcott orders Ellen to mortally wound Shido, Tohka is unable to do anything due to the barrier separating them from her. She eventually snaps and transforms into her Inverse Form.
Hair Decorations: Her red ribbons while not in Spirit form, and a purple, butterfly-like ribbon while donning her Astral Dress. Said purple ribbon becomes edgy in design when in Inverse Form.
Idiot Heroine: She's the most prominently featured Spirit in the story, despite most of the volumes being dedicated to the capture of other Spirits, and one of the strongest fighters. Of course, her airheaded personality is often at the helm of lighthearted moments.
Innocent Fanservice Girl: In the OVA, she takes a naked picture of herself in a photo booth and gives it to Shido, because Reine told her that anytime she takes a picture she should strip naked to do so. Unfortunately he brought said picture to school, and accidentally drops it, and apparently forgot about it until that point.
Insecure Love Interest: Despite Shido's reassurances, she sometimes feels she's not good enough for him, and worries he'll get tired of her antics and leave.
Lady of War: Has an elegant Astral Dress which comes with a Battle Ballgown, hence the codename "Princess". She's also very skilled with her Sandalphon, which she swings around with unparalleled grace.
Laser-Guided Amnesia: The most extreme case among the Spirits who aren't originally humans. She doesn't even remember her own name, creating a lot of Fish out of Water situations throughout the story. When Tohka takes on her Inverse Form, she temporarily forgets that she ever knew Shido, or that he gave her name for that matter, essentially reverting to her pre-Heel-Face Turn state. After Shido kisses her, she remembers him, but at the same time has no memory of what just happened there.
New Transfer Student: At the end of Volume 1, Ratatoskr fills her an application to be in the same school as Shido. The disguise is so great that the AST ends up dismissing her as not being the Princess they were chasing up until then.
Purple Is The New Black: Her Inverse form's Astral Dress is of a noticeably darker purple than her usual attire, and it has more sinister connotations, in line with the cause of her Inverse Form's activation. She also channels dark energy throughout the entire DEM building, and black clouds gather around her as she winds up for one of her tremendously powerful attacks.
Rank Inflation: Her threat level as a Spirit is stated to be AAA-class, higher than Yoshino and Miku, who are B-class and A-class respectively. But then, her Inverse Form is taken up to SS-class, the highest threat level seen so far, even surpassing Kurumi's S-class. Only a Origami-turned-Metatron is able to nearly match her in terms of spirit mana during their rematch in volume 10, both normal and Inverse.
Superpowered Evil Side: When Ellen stabs Shido from behind, in front of her, and is about to finish him while he's down, her emotional stability goes down the drain and she transforms, showing for the first time just how dangerous an Inverse Form can be; not only does she scoff all of Ellen's attacks, but forces the latter to retreat, before turning her attention to Shido and Miku. It takes a kiss from Shido to bring her back to normal.note Kotori almost became consumed by her bloodlust when she tapped into Efreet for too long.
Sword Beam: Her main form of attack as a Spirit. Becomes even more impressive when she uses her Angel for her Finishing Move Halvanhelev. Her Inverse Form ups the ante and, with a single slash from the Finishing Move Paverschlev, creates a Sword Beam so powerful that it not only wipes out most Kurumi clones and Bandersnatch drones fighting in the vicinity, but also cleaves a very large portion of Tenguu City.
Undead Tax Exemption: While some characters comment on her background, no one seems to bring up her being a Spirit while she's in the same class as Shido, including Origami, oddly enough. The novel explains why: Reine gave Tohka such a detailed background that Origami's superiors up to the highest ranks were not convinced she is the same being as the Spirit known as Princess and have denied her every attempt to investigate her directly as she apparently has all the paperwork on file that she is nothing more than a normal citizen much to Origami's frustration.
Wingding Eyes: In the OVA, her eyes become starry when she shows her new phone to Shido.
The Worf Effect: While she's consistently shown to be one of the strongest Spirits in a straight-up fight, Ellen easily defeats her twice, making a point about the latter's status as the world's strongest Wizard. She hands one to Ellen instead upon the introduction of her Inverse Form.
The second Spirit to appear. She's very shy and relies on her Hand Puppet Yoshinon to communicate with others. She causes rain to fall whenever she appears, which is part of her ability to control the three states of water. Mainly uses ice attacks though. Shido seals her powers at the end of Volume 2, and later lives in an apartment specifically built for sealed Spirits.
Code name: "Hermit" Angel: Zadkiel (Puppet) Astral Dress: El
Animal Motifs: Rabbit. Her raincoat's hood sports bunny ears, and her puppet Yoshinon is also rabbit-like. Her Angel Zadkiel even takes the shape of a massive ice hare.
Because You Were Nice to Me: Much like Tohka, Yoshino becomes a little friendlier thanks to Shido being nice to her rather than trying to shoot her on sight.
Berserk Button: Implying to Yoshinon that Yoshino and Yoshinon are separate is sure to rile Yoshinon up, if Yoshino hasn't warmed up to you yet.
Blank White Eyes: During the search for Yoshinon, Yoshino's stomach starts to growl, and Shido asks if she's hungry. She tries to deny, but it growls again, making her blush and display these in embarrassment.
Chekhov's Gunman: In the anime, when it suddenly starts raining during Tohka and Shido's first date in Episode 3, you can see Yoshino in front of the arcade they take shelter in. Naturally, the following episodes focus on her as the second Spirit Shido meets.
Consulting Mister Puppet: Yoshino is a good example as she is almost never seen without her hand puppet Yoshinon, and woe betide the people around her when she accidentally lets go of Yoshinon.
Dandere: Yoshino plays this trope straight, being shy except when around Shido (and even then, she sometimes struggles to speak). Her puppet Yoshinon on the other hand completely inverts it.
Dark Horse Victory: Wins a date with Shido over Tohka and Origami who had been competing with each other for most of the session. To be fair, Yoshinon had declared earlier on that Yoshino would win, though that was likely said in jest.
"Do It Yourself" Theme Tune: Iori Nomizu sings the second and third ending credits (as well as Yoshino's own end-of-arc song), and is also part of the band "sweet ARMS", which does the opening song for both seasons.
Eyepatch of Power: Yoshinon, as well as Yoshino's Angel Zadkiel. The latter is a straight example in that its strength and resilience are enough to ward off the AST more than once.
Fragile Flower: She's much more passive than the other Spirits and has trouble articulating full sentences at first, largely relying on Yoshinon to do the talking for her. This changes as she warms up to Shido, and later volumes has Yoshino converse with him without using Yoshinon.
Gratuitous English: At the very end of episode 5 of the anime, Yoshinon says "To be continued!"
An Ice Person: While she's said to be able to manipulate all three states of water, this is the main application of her Spirit powers, whether it's bringing up a large blizzard, freezing her opponents' feet or shooting stalactites.
Nice Hat: Wears one after her powers are sealed. Her rabbit-eared coat is pretty neat also. In fact, it's stated that she likes wearing cute hats.
Only One Name: One of two Spirits who doesn't have a last name, the other being Natsumi.
Power Incontinence: Suffers this even more so than other Spirits; if anything happens to Yoshinon, Yoshino's mental state becomes unstable and she ends up either causing rain (at best) or freezing stuff around her (at worst). Also, it rains whenever she comes into this world.
Power Limiter: Sort of. Yoshinon calms her down enough for her not to use her powers on others.
Red Oni, Blue Oni: In a single person. Yoshinon is the outspoken fellow while Yoshino is a shy girl.
Shy Blue-Haired Girl: In addition to being An Ice Person, she's extremely shy and soft-spoken. She deals with this by communicating through her hand puppet Yoshinon whenever the situation calls for a more extroverted approach.
Snarky Nonhuman Sidekick: Yoshinon, being the talkative personality of Yoshino, spends a large amount of its screentime making sarcastic comments on anyone and everyone.
Tender Tears: When she's reunited with Yoshinon thanks to Shido. After that, whenever something happens to Yoshinon...
Token Mini-Moe: She's the second one to be introduced in the story after Kotori, with her shy attitude making it more appropriate than Kotori's. Later volumes has her contending with Natsumi's true form as well.
The third Spirit to appear, and the most brutal so far, having had a kill count of over 10000, and one of the few Spirits so far in the series to actively kill people with her powers rather than by spacequakes alone. She kills her targets by dragging them into her shadow, "eating" them, thus replenishing her lifespan so she can cast her powers.
Anti-Villain: Eventually becomes this, given her actual mission (given to her by the enigmatic Phantom) consists of making so that the First Spirit never caused that cataclysmic spacequake 30 years prior to the story. She was actually accumulating lifespan in order to attain enough power to travel back in time for this purpose.
Ax-Crazy: She doesn't waste time in demonstrating just how much of a psycho she is, killing people left and right with a disturbing chuckle, though most of those she kills appear to be Asshole Victims.
Blue and Orange Morality: It's somewhat difficult to pinpoint what her motives in the story are. On one hand, she murders people for the sake of replenishing her time-based powers and accumulating enough lifespan to travel in the past and kill the First Spirit, both which are sound enough by Spirit standards. On the other, it's not even clear why she even follows Phantom's directives in the first place.
Cast from Lifespan: Her 12 Bullet time powers. A rare case of the lifespan being replenishable... by killing other people (which makes it more of Cast from Hit Points). After being defeated by Kotori, she no longer kills them, but just weakens them.
Casting a Shadow: Her City of Devouring Time. Also, when she summons her clones it gets dark.
Cosplay Otaku Girl: Shown to be this in one of the short stories, even getting into a Meido outfit along with Origami.
Cute and Psycho: Unlike the rest of the Spirits who are sweet (or Tsunderes in certain cases), her sweet demeanour is only a front for her psychotic personality.
Dark Action Girl: Unlike the other Spirits, she is very aware of her murderous actions, and is the most dangerous one to date with a S-level threat classification, Inverse Form Tohka notwithstanding. She even manages to defeat Tohka, Origami and Mana successively during her date with Shido, and later on stall out the Yamai sisters, who were under Miku's control.
Dark Is Evil: She's able to control shadows as part of her powers, and prominently dresses in dark colours save for her red Astral Dress. She's also completely bonkers as far as Spirits go.
Elegant Gothic Lolita: Her Astral Dress sticks to the definition and adds crimson and black frills, even though she isn't a loli.
Enemy Mine: She helps Shido out with Miku, after the latter uses a Hypno Ray and turns a lot of people, along with some of the spirits he's sealed so far. She doesn't make it clear why she's helping him though, whether to repay him for stopping Kotori from killing her, or because of It Amused Me.
Evil Laugh: Quite a few times, notably when she summons a second spacequake before Kotori in her Spirit form stops it.
I'm a Humanitarian: She repeatedly states that she will one day "eat" Shido. This is because Shido has other Spirits' powers sealed inside him, something which would undoubtedly net Kurumi enough power to accomplish the mission given to her by Phantom.
Its Pronounced Tro PAY: The kanji in her name is not pronounced as Kyouzou, as noted in the afterword of Volume 3. It's even lampshaded by Tohka in the spinoff manga Date A Origami.
Indirect Kiss: Kurumi and Shidou share one in the Date-A-Live Drama CD, when Shidou gives Kurumi some of the drink he's already had. Kurumi takes note of it.
Kurumi: Ufufu...this makes it...an indirect kiss, right?
Kind Hearted Cat Lover: No, really. Her love and kindness for small innocent animals is the closest thing to a humanizing emotion that she has.
Knight of Cerebus: So much that the anime stuck a Breather Episode before her arc; once she makes her appearance, civilians die en masse, and none of the protagonists are able to talk her out of it. It takes an even more powerful Spirit to take her down.
Large Ham / Evil Is Hammy: The way she talks at times, especially towards her opponents, seems to sound this way, almost as if she's mocking or teasing them.
Magical Eye: Her left eye represents the lifespan she has left.
New Transfer Student: At the start of Volume 3, she infiltrates Shido's high school through unexplained methods in order to get closer to him.
Pet the Dog: For a mass murderer, some of her actions are actually quite considerate.
She's repeatedly shown to have a soft spot for animals such as cats. When she stumbles on a bunch of kids abusing a kitten, she kills them not to replenish her time, but because they preyed on the small animal.
In volume 10, when Origami, who just got turned into a Spirit, comes to her in order to travel five years in the past using the Twelfth Bullet, Kurumi jokes about how she might just want to see a young Shido. Upon seeing Origami's circumstances and determination, however, Kurumi relents, but with the condition that Origami uses her own spirit energy to power the time travel, as well as the excuse that she'll be the guinea pig for Twelfth Bullet's powers.
Self-Duplication: She is able to make duplicates of herself. This allows her to spy and gather information safely, and even if the duplicate is killed, their collective memories return to the original. This ability also becomes tremendously useful during the Miku arc when she's helping Shido and fights multiple opponents regularly.
Shameless Fanservice Girl: She has no issues with teasing Shido, such as showing him her panties when he asks about that from a choice of dialogue Kotori accidentally gave him.
Slasher Smile: Comes with being Ax-Crazy. She sports this most of the time she is wearing her Astral Dress. And a few times without it.
Superpower Lottery: Seems to be more powerful than the other Spirits shown so far and the only one with two unrelated domains of effects (Shadows and Time). Also, the only one with a drawback on her powers (in her case, her life), which she can mitigate through killing anyway. Doesn't stop Kotori from curbstomping her, though.
The Tease : She really likes teasing Shido. Seems to be part of the reason she hasn't eaten him yet. She kicks this up a notch in the Miku arc, even going so far as to lick his cheeks and playfully nibble on his ear.
Time Master: Her primary ability, where she shoots bullets of varying effects.
Vigilante Woman: Most of the victims she kills are would-be rapists and animal abusers.
Wake-Up Call Boss: She's the first Spirit that is against Shido trying to help her. On top of that, she also manages to prevent the other characters he's relied on up to that point from helping in their usual fashion.
Well-Intentioned Extremist: The reason she kills so many people is for the sake of gaining enough power to travel back in time and prevent the first spacequake which claimed 150 million lives.
Wild Card: Though she ceases antagonizing Shidou and his friends after her arc as well as helping out on occasion, i.e. helping Shidou rescue Tohka in volume 7 and granting the new made Spirit Origami's wish to send her back five years so that she can kill the Spirit that killed her parents, and even choosing to merely drain her victim's time as opposed to killing them and taking all of it, she essentially is just going along with her own whims. She essentially stops killing people just to keep a low profile so she can restore her time after draining it in her battle with Efreet, she helps Shidou essentially to have him be a distraction while she searches for info (which even admits upfront), and she grants Origami's request to see whether or not someone can change the past, since that's her goal as well. She also sends Shidou back five years to help Origami after the latter comes back a broken wreck due to killing her parents.
The Worf Effect: She gets hit hard with this at the beginning of Volume 4 (Episode 10 of the first season) just to show that her powers aren't up to snuff in the face of Efreet!Kotori's Superpowered Evil Side.
Yandere: Downplayed even though most fans consider her to be a "true" Yandere. What sets her apart from most archetypes (like Yuno for example) is that her murderous actions are solely based on replenishing her depleting Life Energy above anything else and even then, she is only interested in Shido because of his power. Not because she's overly attached to him out of jealousy.
Your Princess Is in Another Castle: Or rather, the Second Spirit is imprisoned elsewhere by the DEM. And the Second Spirit? The key to finding the actual target, the First Spirit. During the events of Volume 6, she helps Shido rescue Tohka, but only because he makes a good distraction so she can find the Second Spirit. She fails, though.
Twin Spirits who appear in Volume 5. They were originally one entity, but for reasons unknown got split into two: Kaguya and Yuzuru. These 2 have very distinctive personalities, and the original personality is gone. They cause a storm every time they appear.The duo have been fighting 99 times to determine who is the real Yamai, with 25 wins each and 49 draws. On seeing Shido, they decided that their 100th and final battle will be to see who can seduce Shido first.
Combination Attack: They can do these in battle. Or when playing beach volleyball. Or seducing Shido. Also, this is how they manifest the bow El Kanaph, which is the true form of their Angel. They pull one off with Yoshino in book 9, blowing away an AST team that dropped their territories to avoid Yoshino freezing them.
Cry Cute: When they finally admit to each other that they want to live on together. Kaguya plays it much straighter than Yuzuru.
Ham-to-Ham Combat: They engage in this when they first appear before Shido episode 2 of season 2.
Heroic Sacrifice: Both girls privately tell Shido to pick the other one in episode 3 of season 2, because they care deeply about the other girl, and want them to live on and sacrifice their own body/spirit in the process. Fortunately Shido offers them a third option, and his decision allows both of them to survive.
Lightning Bruisers: The Ratatoskr data book gives them very high stats all around (with the highest being their agility), with the exception being intelligence (though nowhere as low as Tohka). This is quite appropriate for their threat level as AAA-class Spirits. It's also said that their Astral Dress doesn't give them much defence, but also that it wouldn't matter given their power over the wind.
Ms. Fanservice: They're Spirits with a veryrevealing Astral Dress, and they're properly introduced in the middle of a Beach Episode arc. Naturally, they get the lion's share of volume 5's fanservice.
New Transfer Students: They join Shido's school (though they're not in his class) in the middle of Volume 5, right in the middle of a field trip. Naturally, Reine has to make up an explanation to Tamae on the spot.
Not So Different: Both Yamai girls appear to hate each other quite a bit, but Shido finds that they can also work quite well together when they have to.
Ojou Ringlets: They both got them and they are really long. Probably because they look like cyclones of course.
Power Gives You Wings: They each gain one wing when they manifest their Angels. These two wings form the two limbs of their Angel's actual form, a bow.
Large Ham: On top of being hotheaded, she uses a very dramatic and nearly unrealistic vocabulary, in contrast to the calmer Yuzuru. It's later revealed that she's just acting; she believes being a Spirit is "super awesome", therefore she must act appropriately.
Kaguya: "I'm the Kama Sutra incarnate!"
Petite Pride: While the twins` cup size aren`t that much different from each other, when Yuzuru tries to invoke Buxom Is Better in order to win over Shido, Kaguya is quick to answer that sacks of lard can't even begin to compare with her own slender body.
Buxom Is Better: While the twins` cup size aren`t that much different from each other, she invokes this in regards to fighting over Shido against Kaguya, claiming that large breasts are a must. The latter is quick to say the contrary.
Chain Pain: Her weapon El Nahash is depicted in the anime as a very long chain.
First appears in Volume 6. She is shown to be an Idol Singer, with her Spirit power being a magic voice. Hates guys a lot (girls don't fare much better; she sees them only as slaves fit to serve her), so Shido had to crossdress just to approach her. It works; Miku ends up becoming really fond of "Shiori".
Code name: "Diva" Angel: Gabriel (Organ) Astral Dress: Shaddai El Chai
Broken Bird: Like Kotori, she used to be a regular human girl. She was an up and coming idol, but turned down a producer's offer to do This and That. As a result, he spreads false rumors of a scandal about her, and her agency ends up dropping her as a client, along with her former fans turning against her. She attempted to restart her singing career, but then lost her voice. At one point she even considers suicide, but is stopped when Phantom shows up and makes her a Spirit, thus allowing her to regain her voice, along with the ability to manipulate people with it. Once she regains her voice, she uses it to become a popular idol again, though she retains her intense hatred for men due to her previous experience with them from before.
Cry Cute: When Shido keeps his word and saves her from danger, she stops putting on a haughty attitude towards him and simply breaks down in tears, realizing he is the kind of person she was looking for all this time.
Defrosting Ice Queen: For a measure of letting up her hatred against men and general callous attitude when it comes to using her powers, at least; soon after telling Shido the circumstances as to why she's a Broken Bird, Shido says he'll protect her if she's ever in danger, like he would for Tohka, which she doesn't believe. Then when it really happens, courtesy of Tohka's Superpowered Evil Side, he keeps his promise, and she later trusts him enough to let him seal her powers by the end of Volume 7.
Despair Event Horizon: After falling out of favor in show biz, and losing her voice while attempting to restart her singing career, she seriously considered suicide. Only the appearance of Phantom and it giving her a singing voice again stops her.
Dissonant Serenity: Her first interaction with Shido has her letting him know just how much she hates him... all while having a gentle smile on her face. Only in the text though; the illustration shows her having a disgusted look.
Does Not Like Men: She has a Freudian Excuse for it, given how most of her fans as Tsukino Yoimachi were male and quickly turned away from her after a false scandal stemming from her refusal to do This and That with a producer. She does, however, eventually warm up to Shido after the turmoil of Volume 7.
Evil Cannot Comprehend Good: Pre-Heel-Face Turn, she believed that everyone was just looking out for themselves if it really came down to it. But Shido tells her that he wants to rescue Tohka no matter the costs, and she initially refuses to believe him due to past experiences with other men. However, when she later asks several people/spirits who are familiar with Shido regarding his saving Tohka, they all unanimously agree that Shido would put Tohka before his own life. This causes her to gradually reconsider her hostile stance towards him.
In Volume 8, her removing of said clip so Shido would have something to remember her with if she disappeared gives him the final clue for identifying who Natsumi disguised herself as.
Heel-Face Turn: She eventually warms up to Shido after he goes through a lot to try and protect her.
Idol Singer: She was actually one before becoming a spirit, though loses her voice at the time. Phantom later shows up and gives her the ability to sing again, which she exploits beautifully to her advantage.
I Love You Because I Can't Control You: When she tells "Shiori" that she can make the entire world love her if she chooses to, he replies that he would hate her even more, because her power doesn't work on him. This causes her to tell him that she only wants him more now because of that.
I Was Just Passing Through: She comes up with several excuses for why she chooses to help Shido save Tohka and fight Inverse Tohka.
Jerkass: She sees the Tenguu theatre, where she had never performed before. And she's in the mood to sing. However, there is a large crowd of people in her way. What does she do? Cause a spacequake to get rid of the crowd. She does get better though.
Oh, Crap: For a moment, when she has exhausted the last of her powers against Inverse Form Tohka and can't use them anymore. When her opponent is about to target her next, she forces a laugh and resigns herself to an imminent death... then Shido saves her.
The Tease: Her flirtatious nature with Shido, as well to other Spirits, gives even other teasers like Origami or Kurumi a serious run for their money in this department.
Troubled Backstory Flashback: In Volume 7, she reveals her circumstances for becoming a Spirit to Shido after the latter told her he found some clues about her past as the idol singer Tsukino Yoimachi. She's Trying Not to Cry at the end of it.
Used to Be a Sweet Kid: She was previously known as Tsukino Yoimachi, an up and coming idol. As soon as she turned down a producer's offer to do This and That, though, false rumours spread to discredit her, and her audience eventually turned away from her. At one point, she lost her voice and nearly contemplated suicide, before Phantom came in and answered her anguish with the power of a Spirit.
A Spirit who makes her first appearance in Volume 8. Shido's the first non-AST person she met. Things were going well in his attempt to seal her powers. Then she sneezes, causing a flash of light, and her getting angry at him because he saw something about her that she didn't want him to see (he actually didn't get to see anything). She takes the form of Shido and makes advances on all his acquaintances in school before being found out by Tohka and Origami, after which she escapes and issues Shido photos of 12 people close to him, and challenges him to find her out before they all disappear.
Code name: "Witch" Angel: Haniel (Broom) Astral Dress: Adonainote Adonai is used over Jehovah because Jews believe YHWH/YHVH to be too sacred to use Tzabaoth
Cry Cute: When Shido and other Spirits saves her and all of them forgive what she did before, as well praising her actions. Coupled with Tender Tears.
Cute Witch/Token Mini-Moe: Her true form is that of a young girl around the same age as Yoshino. It's something she's rather not show to people, and promptly punishes Shido and the rest of the main cast for it, turning them into 9-year-old children before making her escape.
Fountain of Youth: Turns the main cast into 9-year-old children once they catch sight of her true form.
Magic Mirror: Her Angel can take the form of a mirror with which she can trap her targets inside.
Master of Disguise: Thanks to her shapeshifting powers, she can turn into whatever she wants. During Volume 8, she disguised herself as Yoshinon, Yoshino's puppet, though the farce is only revealed when Yoshinon was able to react to something Yoshino couldn't, and that Yoshinon knew of its time in Origami's house; both of which were impossible since Yoshinon was a Split Personality of Yoshino, meaning it couldn't know anything that Yoshino didn't, and that outside of Yoshino's control Yoshinon was nothing more than a puppet.
You Are Better Than You Think You Are: After the events in volume 8 and most of volume 9, this is essentially what Shidou tries to do to get Natsumi to open up to him and the rest of the girls. It takes a while to stick.
Fiery Redhead: She's quite hotheaded and can alternate between bothTsundere types depending on the ribbons she wears. It's taken to a litteral level when she reveals herself to be the Spirit codenamed Efreet.
First Episode Spoiler: She's revealed to be the commander of the Fraxinus in the first chapter/episode. The fact that she and Shido are Not Blood Siblings can also count as this in the light novel.
Freudian Slip: While having an argument with Mana regarding who is the better younger sister to Shido, Kotori lets out that blood siblings can't marry.
Girlish Pigtails: Sports long twintails, and is among the youngest characters in the story.
Hair Decorations: Her ribbons. They determine her personality depending on the colour. Horns also stick out next to her ribbons when in Spirit form.
Idiot Hair: Has a noticeable forelock of hair in all appearances.
Important Hair Accessory: Her ribbons, more to show her switching personalities rather than Character Development, though. She'll be the nice little sister with her white ribbons, or the sadistic commander with her black ribbons. This is because when Shido bought her the black ribbons for her 9th birthday, he made her promise to be a strong girl as long as she wears them. Guess it worked too well.
Insane Troll Logic: Her reasoning for making Shido date a Spirit falls on this: to make them harmless, they must come to love this world. Ergo, make them fall in love with you, and they will view the whole world as beautiful!
Volume 3 reveals that she is the Spirit codenamed Efreet, having been turned into one by the Phantom, who then told her to kiss Shido to seal her powers. This was how she learned about Shido's ability to seal Spirits' powers. She takes them back to save him from Kurumi in Volume 3, then has them sealed again in Volume 4.
An Axe to Grind / Blade on a Stick: Her Angel's default form is that of a massive halberd. It can morph into a cannon strong enough to vaporize several of Kurumi's clones, and make a dent in her clock-based powers.
Ax-Crazy: When she taps into Efreet for too long, she starts giving in to bloodlust, nearly killing Kurumi with a maniacal grin before Shido's pleas bring her back to her senses.
Blood Knight: As Efreet, she slowly starts losing control of herself and practically begs for a good fight, taunting a defeated Kurumi about how disappointing of a performance the latter put up.
Evil Redhead: The bloodlust-stricken Efreet is easily as much of a threat as the Ax-Crazy Kurumi, although Shido manages to seal Kotori again.
Healing Factor: Shido's Healing Factor comes from her, who in turn got it from Phantom. She demonstrates just how ridiculous this ability is by shrugging off just about everything Kurumi throws at her before writing her off with her Angel.
Meaningful Name: Her Angel's name means "the severity of God", and her Astral Dress is Hebrew for "Almighty God". Considering just how brutal her victory over Kurumi's Superpower Lottery was, there's no contesting its rightfulness.
Playing with Fire: Her Spirit powers give her control over fire, and nearly all of her attacks are punctuated with violent flame bursts.
Red Eyes, Take Warning: As soon as Kotori's personality gives way to the bloodthirsty Efreet, she violently flashes glowing red eyes.
With Great Power Comes Great Insanity: A classic example; she nearly loses control of herself shortly after defeating Kurumi, and only Shido's pleas to stop snapped her out of it. This got so out of hand that she had to be confined like a Spirit, shortly before starting her own date with Shido.
Wreathed in Flames: When her powers are active, Kotori is accompanied by a blazing inferno.
The analysis officer onboard the Fraxinus. She never gets Shido's name right, and his name is the only one which receives this treatment from her. Becomes Shido's assistant homeroom teacher and physics teacher early on, to facilitate his training. Always looks sleepy.
Artistic License - Biology: Reine claims that she hasn't had any decent sleep for 30 years, after consuming an entire bottle full of sleeping pills, saying they weren't effective enough.
Christmas Cake: If she really is over 30 years old. Though it doesn't seem to bother her.
Vice-commander of the Fraxinus, and a big masochist. When the crew has to make Dating Sim-esque choices, his choices, made purely to fuel his masochism, are the ones being shot down the most.Despite his masochism, he's revealed to be very good at using the Realizer, which really came in handy when the Fraxinus got attacked. With this skill, he was the former ace and captain of the AST squad when Ryouko was new to the team. He defected to Ratatoskr to find a suitable master he can serve under, and he found one in Kotori. However, he left a wish to be reinstated in case he changed his mind.
The Ace / The Captain: Formerly of the AST when Ryouko was just a recruit. Also, when Kotori places the Fraxinus under his command, he shows just how capable he is at directing the crew.
Large Ham: He's the most bombastic member of the Fraxinus' crew, openly admitting his masochist tendencies and his desire to be punished by Kotori. Surprisingly, he shows scant moments of analytic calmness when the situation calls for it.
Lolicon: If his perversion towards Kotori is any indication.
Noodle Incident: While in the AST, he gave his subordinates Cool And Unusual Punishments. According to Ryouko, punishment for first timers was having to cosplay, second timers was having to cosplay and step on him. We don't find out what the punishment for third timers was; all we know is that it's one Ryouko really doesn't want to remember.
Suspiciously Specific Denial: In the filler Hot Springs Episode, when he's trying to convince Kotori to go to the hot spring to stay in top condition. Kotori doesn't buy it, of course, and makes him dig a hole and refill it over and over as punishment. As a Brick Joke, he digs up a hot spring at the end of the episode.
Kyouhei: I have no idea what you mean. I have no desire to install several surveillance cameras there. Would someone like me actually fill a hot springs with lenses so I could stare at every inch of that hard, tight body at my discretion, especially that backside?
Too Kinky to Torture: He might as well exist as Kotori's punching bag. Though he's not too big on the idea of castration or death.
Tranquil Fury: During the fight with the AST ship in episode 4 of season 2, while he throws out some perverted dialogue, he is so eerily calm and issues orders so specific that the rest of the bridge gets a bit nervous. The fact that said orders also help them defeat the enemy ship helps.
The rest of the Fraxinus crew
Members of the Fraxinus crew who participate in the decision making process when the Dating Sim choices come up.
The founder and benefactor of Ratatoskr Machinery, Mr. Woodman appears in Volume 8 to interrogate the captain of the Arbatel. He's said to use an unconventional method of communication and conversation, and is revealed to have once worked alongside the current DEM managing director, Isaac Westcott, before some incident 30 years ago made him defect from the DEM and start his own organization.
Big Good: Kotori, and by extension the rest of the Fraxinus' crew, answers to him, and he opposes Westcott's plans.
Defector from Decadence: Left the DEM to lay the foundations for what would eventually become Ratatoskr. He outright states that Westcott is his main reason for doing so, although Woodman seems to be still on friendly terms with him.
Karen Nora Mathers
Mr. Woodman's secretary, and Ellen Mira Mathers' older sister. Appears alongside the former in Volume 8.
Cain and Abel: The Abel to Ellen's Cain. Both are secretaries to their organisations' respective chairmans. In Volume 8 Chapter 5, it's hinted that she and Ellen were already antagonistic to each other prior to the series.
"There is no problem. I understand my sister and I won’t understand each other from years ago."
A girl who's top in beauty, brains and brawn. Shido's classmate, and has very strong feelings for him, for reasons unknown. Is a member of the AST, and holds the rank of Master Sergeant. Due to the death of her parents to a Spirit, she hates Spirits very much, to the extent of wanting to kill them on sight.
The Ace: She's implied to be one of the better AST soldiers, and has top grades at school.
And Then John Was a Zombie: In her insatiable thirst for power capable of defeating the Spirits, the mysterious entity known as Phantom appears before her and gives her a Sephira Crystal, similar to the ones used to turn Miku and Kotori into Spirits. This transforms her into the very type of being she despises, her Angel called Metatron.
Armed Legs: One of the many AST suits she wears sports a retractable heel blade. This allows her to slash Ellen Mira Mathers, who commends her afterward for being the second one to injure her.
Badass Normal: She's the only human girl within Shido's harem yet she is able to stand up against powerful Spirits like Tohka. During Volume 10, access to Westcott's weaponry allows her to defeat up to four Spirits in their limited Astral Dress releases, only to lose to a full-power Tohka. This defeat is then followed by Phantom's appearance, turning Origami into an Empowered Badass Normal.
In Volume 7, Origami arrives in time to break up the tag-teaming of Ellen and Jessica on Mana, and is able to engage and injure the former, with a little distraction from the Fraxinus' main cannon.
In Volume 9, after Ratatoskr and Shidou's group are done destroying the two satellites that were being used to target Westcott, they're too exhausted to try and stop the third satellite that was prepared for such a situation. Cue Origami destroying it in one attack.
Body Back Up Drive: Following Shido's game-changing act in Volume 11, a new timeline is created in which Origami never lost her parents to Spirits (though they still die of an unrelated accident), completely rewriting Origami's personality into The Ingenue. However, the personality of the old Origami, as well as her Spirit powers, still live on the new timeline's Origami, albeit suppressed for the sake of her sanity given the events of Volume 10 left her old self in a catatonic state. Origami would then occasionally lapse into the old Origami's perverted antics while around Shido, much to her surprise and horror. It is not until she fuses her personality with the old Origami that she comes to term with what happened during the course of Volumes 10 and 11 and regains all memories from the previous timeline, with her finally letting go of her grudge against the Spirits and asserting that she truly loves Shido.
Broken Ace: Despite being one of the finest AST members, her obsession with avenging her parents turns her into The Unfettered, and sometimes ignores her superior's orders in favour of charging headfirst against Spirits.
Broken Bird: Once upon a time, she was a cheerful little girl. Then her parents were killed by a Spirit and she's now a stoic and ruthless Child Soldier driven by the desire of revenge.
Byronic Heroine: Her motivation to kill Spirits, due to the deaths of her parents by one, is an integral part of her character. Even in her streak of revenge, she's never really presented as a true antagonist.
Child Soldier: Joined the AST after her parents were killed by a Spirit.
Clingy Jealous Girl: Towards Shido. In Episode 10 of the anime, while trying to visit Mana at the hospital, Shido runs into Origami who was walking. She asks him if Tohka is okay, and when he tells her she is, Origami lets off an annoyed grunt. She later insults and patronizes Tohka in Episode 11 while picking out a swimsuit.
Crazy-Prepared: Specifically, her house. As in sentry guns are there to keep intruders out. There's even signal jamming.
Cynicism Catalyst: The death of her parents at a Spirit's hands is the cause of her undying hatred for Spirits and her extreme ruthlessness.
A Day in the Limelight: While she was an important character throughout the story, she was overshadowed in favour of the Spirits that Shido attempts to seal. Volume 10 is dedicated to answering the ordeals driving her character, and some more.
Easily Forgiven: She apologizes to Shido in the classroom for shooting him. He's embarrassed, so he accepts her apology rather quickly. And after her antics at the end of season 1, which should have probably landed her in jail for a few years at the least, she's instead suspended for two months, thanks to some intervention by a high ranking AST official.
Face-Heel Turn: While she was at best a Byronic Heroine, her fixation on finding her parents' murderer leads her to ally herself with Isaac Westcott, who provides her with new weaponry. It doesn't stick, as she constantly ignores his orders, and has a run-in with Phantom, who promptly turns her into a Spirit, ending her shaky partnership with Westcott.
Fantastic Racism: She hate Spirits due one of them responsible for her parents death. Volume 10 reveals the Spirit who responsible was herself all along.
Faux Action Girl: Downplayed, then deconstructed. She is a genuinely good fighter as far as humans go, but against Spirits she's still outclassed, and has to use dangerous weapons like the WhiteLicorice to even pose a threat to them. Unfortunately, this also has the side effect of fueling her thirst for even greater power, which eventually forces her to join forces with Westcott during Volume 9. Things escalate for better or worse in Volume 10, when she is turned into a Spirit by Phantom's Sephira Crystal.
Hero Antagonist: Her desire to destroy Spirits clashes with Ratatoskr's peaceful methods, and some conflicts in the story could have been avoided if not because of her Revenge Before Reason attitude.
Heroic BSOD: The revelation that she's the one who killed her parents hit her so hard that even after Inverting she becomes completely unresponsive to anything around her, akin to a corpse by Shido's words and unrecoverable by Kurumi's.
Icy Blue Eyes: Her blue eyes match her very cold and stoic personality.
Instant Armor: In Volume 10, she initiates a fight against the sealed Spirits by calling forth her new personal Combat Realizer outfit, given to her by the DEM.
Jerkass: She shows little respect towards Tohka given the enmity between Spirits and the AST, as well as seeing her as a love rival for Shido. In Volume 10, upon realizing she's become accustomed to life with the Spirits, she snaps and promptly engages them in battle.
Morality Chain: She has one in the form of Shido, despite the usual Stalker with a Crush antics. When she attacks Kotori, who is revealed to be the Spirit codenamed Efreet and Origami's prime suspect in her parents' deaths, Origami is only stopped by Shido because she readily believes his words about the incident having been caused by another Spirit, as well as herself not wanting to kill Kotori. She later admits that had she not known that, she would've killed Kotori without regret.
Mystical White Hair: One of the few characters to sport white hair, and definitely stands out from most of the cast note The other characters are Isaac Westcott, who has dark ash blonde hair, and Maria Arusu, a videogame-exclusive SpiritThe significance of her hair colour is strengthened when she becomes a Spirit with powers over light.
Nice Job Breaking It, Hero: Frequently has moments like these due to her extremist tendencies. Her attempts to subdue Spirits with violence often makes things worse instead of better. Like accidentally sniping Shido and enraging Tohka, when she was just about to be sealed.
One Woman Army: She takes on Bayley and her DEM team by herself when she finds out that the latter had orders to kidnap Shido and Tohka. And with her nifty upgraded suit, she's able to take them head on for much of the fight.
Red Oni, Blue Oni: The Blue to Tohka's Red. Most of the time, the gullible and brazen Tohka will fall for Origami's subtle provocations.
Reused Character Design: Her appearance and personality is actually recycled from tsunako's previous work on Hyperdimension Neptunia mk2's Kei Jinguji; both sport short white hair and stern blue eyes, are prone to making sarcastic comments. However, they also contrast each other by the way they approach people: Kei tries to be more sociable but doesn't know how to do so, while Origami actively keeps to herself.
Revenge Before Reason: For example, her attempt to kill Kotori by stealing high grade weapons then firing them in an amusement park full of civilia wasn't particularly wise. Revenge is so much a part of her existence that when she realizes that she's beginning to accept Spirits (particularly those that have had their powers sealing like Tohka) her response is to try and kill that part of her along with said Spirits. In her words, reclaiming herself.
Self-Made Orphan: After having gone back five years in time to fight Phantom in a fit of revenge for having turned her into a Spirit, a stray attack of hers ended up killing her parents. Which means that she was the one who killed her own parents five years ago, and caused her extreme hatred of Spirits.
Shameless Fanservice Girl: She has no qualms about trying to seduce Shido, and will often get close to him and when making him take her temperature at the hospital, sits on his lap to do so. In the OVA, she even obeys his orders to put on a School Swimsuit with dog ears and tail, then act like a dog. In public.
She Who Fights Monsters: As the story progresses, Origami's hatred for the Spirits is such that she takes increasingly drastic measures to obtain power in order to annihilate them, going from illegally taking possession of the WhiteLicorice to allying herself with Isaac Westcott. This culminates in volume 10's encounter with Phantom, who gives her the power of a Spirit, at the cost of terrible revelations.
Skyward Scream: She lets out one after she realized that she killed her own parents.
The Tease: She doesn't waste any time doing this towards Shido every chance she gets.
Took a Level in Jerkass: By the time of Volume 10, she realizes that she got used to living with the sealed Spirits. However, because she still holds a grudge against them, she decides to put an end to that and attacks Tohka, Miku and the Yamai sisters, resolved to come back to a normal life. Even when she becomes a Spirit, and despite Tohka's offering to understand each other, Origami insists that she will reject all Spirits, despite having become one herself.
Took a Level in Kindness: While she still obstructs Shido from time to time, in season 2 she's much less stubborn and actually helps him out quite a bit, such as distracting the DEM team sent to capture Tohka and Shido during their contest with Miku.
Too Kinky to Torture: For lack of a better word, at least; she's so indifferent to her environment she'd do anything Shido asks her to do without hesitating even a second and absolutely not a care to other people's reactions. Which means that if he were to ask her to dress up an embarrassing costume and get on all fours, she'd do just that, as seen in the OVA (it involves a school swimsuit, dog ears/tail and a leash that is actually Shido's belt that she wraps around her neck herself).
Used to Be a Sweet Kid: Before the death of her parents, she was your usual cheerful elementary school kid with the dream of becoming a beautiful bride in the future. Now she won't hesitate to kill a Spirit when just looking at it. The author even states that her Spirit form's dress is meant to convey that shattered dream of becoming a bride.
Van Helsing Hate Crimes: She hates Spirits with passion and they're all evil monsters in her eyes, even though it's very clear that not all Spirits are bad.
When She Smiles: The cover of Volume 11 marks one of the few times Origami is genuinely smiling. Even if by that point she has triggered the Inverse Form of her newfound Spirit powers.
White Hair, Black Heart: Has white hair and while she's not exactly evil, she's not a pleasant person and her strong hatred for Spirits make her a dangerous Anti-Hero.
You Killed My Parents: This is the reason why she is so hell-bent on fighting the Spirits. After seeing Kotori's powers in action, she immediately suspects and tries to eliminate her. Turns out that wasn't the case, and that it was another Spirit who did it. Volume 10 reveals that spirit was herself.
You Shall Not Pass: She delays Bayley and her DEM team from kidnapping Shido and Tohka during a festival in episode 6 and 7 of season 2. By herself.
Zettai Ryouiki: While dressed up as a Meido when Shido visits her. Also when she's in her CR-Unit, as well in Spirit form.
Major spoilers below
Click here to see "Angel" (SPOILERS)
At the end of Volume 9, Origami's intense thirst for revenge against the Spirits made her turn to Isaac Westcott, who was coincidentally looking for a capable fighter. Using new and improved Combat Realizers, she fights the Spirits once again in Volume 10, only to brought down by Tohka. It is then, in her defeat, that she pleads for even more power, prompting the enigmatic Phantom to make its appearance, granting her a Sephira crystal that turns her into a powerful Spirit.
Code name: "Angel" Angel: Metatron (Crown) Astral Dress: EHYHnote Ehyeh Asher Ehyeh (lit. I Am that I Am)
Tropes applying to Origami's Spirit form:
Attack Drone: "Kadour - Sword of Light" has Origami break up her formation of light pillars and send them individually after her opponent, each gaining a will of their own.
Barrier Warrior: One of her Angel's abilities makes her pillars of light surround her, blocking any incoming attack.
Beam Spam: Her main form of attack, "Shemesh - the Sun", has her make the surrounding pillars of light spin around her and gather light particles, releasing them as a rain of energy blasts. This proves problematic for Tohka, who, as a close range warrior, can't even get near her for a good part of the fight.
Cool Crown: Her Spirit form's Astral Dress has a large golden headdress which looks like a crown that's twice as large as her head. Similarly, her Angel's default form, Metatron, possesses several pillars of light that surround her and, when put together, resembles a giant crown. This changes into a black, spiky halo once Origami takes on her Inverse Form.
Empowered Badass Normal: While she was a Badass Normal at the start of the story, Volume 10 elevates her to new heights by turning her into a Spirit capable of rivaling Tohka at her strongest.
Hard Light: Her pillars of light are described as feathery and golden.
Light Is Not Good: Her mental state after Phantom turns her into a Spirit with control over Light couldn't be any worse; she deduces that Phantom, due to its association with Kotori's empowerment, might be responsible for her parents' deaths, and promptly goes on a crusade against the mysterious entity, even crossing time five years into the past to do it.
Power Gives You Wings: One of the abilities of her Angel Metatron, "Mal'akh - Heavenly Wings", allows her to fold her pillars of light into wings and fly around at great speeds.
Power Makes Your Hair Grow: After sinking into despair and tapping into the even more powerful Inverse Form, Origami's shoulder-length bobcut grows down to her waist.
Stripperiffic: While her Spirit attire as Metatron is quite tame by Spirit standards, her Inverse Form follows Dark Tohka's trend, baring her shoulders and midriff, as well as making her dress more skimpy.
Teleporters and Transporters: Origami is able to turn herself into light and warp away to a safe location, although Tohka deduces that she can't use this continuously since the destination is predictable and unlikely to avoid a large attack.
Walking Spoiler: This Spirit form is the culmination of Origami's desire to become stronger, something which was granted by Phantom's Sephira Crystal, another major spoiler when talking about how some of the Spirits were originally human.
Wave Motion Gun: "Artelif - Crown Cannon", in which the pillars assemble into a circular motion and fire a beam of pure light.
You Are What You Hate: Not only she becomes one of the Spirits she hates so much, she's the Spirit who killed her own parents in the first place.
The Comically Serious: She orders her AST squad to prepare for a mission... while packing on luggage for said mission, which is a trip to the hot springs.
Cool Big Sis: Towards Origami and the members of her AST squad.
Could Say It But: After getting ridiculous orders by the DEM squad that is placed with her team, she goes to the room that Origami (who she has been ordered not to include in or even let know that there is a mission) is changing in and proceeds to rant about the mission to attack Tengu square during the festival while people are still there and kidnap Tohka and Shidou, as well as lamenting the fact that she's so angry that she might just leave the room with the special weapon White Licorice unlocked.
Rage Breaking Point: Normally she keeps a professional attitude about everything, but when she gets fed up with the obstacles in the way of her squad's trip to the hot springs, in addition of the previous stress built up due to her superiors' rantings, she snaps and comically goes on a rampage to destroy Ratatoskr's traps.
Reasonable Authority Figure: Cares deeply for her team and the citizens that she's protecting. When the DEM starts giving questionable orders, she does everything she can to do her duty to her squad and the people of Tengu city.
Shido's real sister. She was transferred from the DEM to the AST, where she holds the rank of Second Lieutenant, callsign Adeptus 2, to aid the Anti-Spirit efforts. She underwent a procedure to strengthen her body, making her a Wizard, and in exchange has only 10 years to live. In Volume 6, she is revealed to have defected to Ratatoskr, having been informed of this truth.
Action Girl: And a pretty badass one at that. She's stated to have killed at least one spirit (although it later turns out to be one of Kurumi's lesser clones), and saves Origami from Bayley's group in season 2 singlehandedly.
Arch-Enemy: She and Kurumi are constantly at each other's necks. Even when Shido tells her they have to work together with Kurumi temporarily, Mana begrudgingly accepts to assist.
Child Soldier: Par for the course for most Wizards recruited by the AST / DEM, but it's exacerbated by the fact that she has no memory of her past except for a pendant which holds a photo of her child self and a young Shido.
Clingy Jealous Girl: Towards Shido when Kotori is around, as she can't stand the fact that Shido has joined an organization with lots of contact with the Spirits and criticizes Kotori for it.
"Do It Yourself" Theme Tune: Her Japanese voice actress, Misato, is one fourth of the band "sweet ARMS", which performs both opening songs.
Heel-Face Turn: She defects to the Ratatoskr's side after finding out what DEM did to her body.
Laser-Guided Amnesia: Mana forgot who her brother was. The only clues she had of him were a photograph of him and that she remembered calling him "onii-sama".
Mercy Kill: After seeing Bayley's sorry state after exerting herself too much just to pilot the Scarlet Licorice, Mana reluctantly kills her, but not before falsely reassuring that Westcott will acknowledge her.
Super Soldier: She specifically underwent augmentations to become a Wizard, and it shows when she's able to mop up anything that's not a Spirit or Ellen, living up to her rank as Adeptus 2.
Your Days Are Numbered: She has only 10 years left to live, having undergone a procedure to strengthen her body enough to fight on par with Spirits. She's not told of this side-effect until Volume 6, and when she learns this, she defects to Ratatoskr.
A girl new to the AST who idolises Origami. She holds the rank of Private in the AST. Is also in Shido's school and in the second year, but having skipped one grade is one year younger than her peers. Is Tamae's cousin. She's the main heroine of the spinoff manga Date A Strike/Date Ast Like.
New Meat: One of the most recent arrivals in the AST.
The managing director of Deus Ex Machina (DEM) Industries, a corporation based in England, and the only known industry able to manufacture Realizers. His aim is to get Spirit powers to rewrite the laws of reality. The true meaning behind this is unknown.
Arch-Enemy: He and Woodman have been hostile to each other ever since Woodman left him and Ellen at some point. He also feels this way to Shido during Volume 7 (episode 10 of season 2), though nowhere as intense as with Woodman.
Bad Boss: He treats his subordinates, even the loyal ones, as disposable pawns in his grand scheme.
Big Bad: While he was relatively out of the picture for the first four volumes or so (the entirety of the anime's first season minus his involvement with Mana and Origami's new weapons), once he makes his appearance, it's made clear that he harbours ill intent towards the Spirits, and slowly overrides the story's basic Excuse Plot.
The Caligula: While he's the Managing Director of DEM Industries, he never shows concern for his subordinates and even the company. Anyone who dares to oppose him will lose their lives.
Card-Carrying Villain: Admits that he loves war, chaos, annihilation, destruction, and the deaths of women and children, and he'd do anything to create a world of despair.
Corrupt Corporate Executive: Of Deus Ex Machina Industries. On one hand, he was the one who invented the Realizers. On the other hand, he wants to seek and harness all of Spirit powers so he can rewrite the laws of reality according his own image.
Evil Brit: He's the head of a company based in England, and he himself holds the title of "Sir". He's also the emerging Big Bad of the story.
Evil Former Friend: He shares a history with Woodman, having worked together alongside Ellen prior to the beginning of series.
Greed: He's really obsessed about harnessing the powers of a Spirit's true form.
Hate Sink: Of all the antagonists that appear in the story, Westcott is the corrupt ringleader of an organisation full of psychotic mercenaries, and even then treats them like disposable pawns. It says something when the main characters instinctively grow wary around him.
Icy Blue Eyes: A bit dark on the colouring, but his eyes are of a dull blue that give away the fact that's he's a cunning and sinister schemer.
Knight of Cerebus: Once he starts meddling with the protagonists, particularly Tohka, the story progressively becomes more than just a race to seal the most Spirits.
Older Than They Look: He's described as being around 30 years old, but Origami notes that he gives off the impression of an experienced veteran. Mr. Woodman also states that he left the DEM 30 years ago due to a fallout with Westcott.
You Got Spunk: He says he enjoys people that are willing to attack him. When he found out that Murdock was trying to kill him, Westcott smiled and said if he ever got back to England, he would congratulate Murdock.
The secretary of Sir Isaac Westcott, and the strongest Wizard in the world, callsign Adeptus 1. Is very loyal to his cause, and has vowed to never lose to any opponent.
The Ace: She's by far the most competent human fighter introduced, and completely dominated Tohka during their first fight, even breaking her Sandalphon in the process.
Adaptational Attractiveness: Her depiction in the anime is more prim and proper than the wild, battle-hungry appearance she sports in the novel.
Arrogant Kung-Fu Guy: The most competent fighter, as well the most boastful and arrogant character in the series.
"Nothing alive on Earth can beat me..."
Ax-Crazy: Her calm and analytical façade gives way to a bloodthirsty, murderous and battle-crazed persona once she enters the battlefield.
Barrier Warrior: Unlike most AST / DEM Wizards, she's able to concentrate a field around a specific target, which she promptly uses to subdue a captive Tohka in case the latter's temperament gets out of hand. In her battle suit, it's powerful enough to deflect a Wave Motion Gun from the Fraxinus.
Boobs of Steel: She's really well-endowed, easily bigger than most of the Spirits. And she's the first human to outright defeat a Spirit at full power.
Butt Monkey: Trying to trail her target during the school trip has the unfortunate effect of being on the receiving end of Ai, Mai and Mii's antics. Such as falling into a sand trap, or getting hit by a stray pillow. In "Ellen Mathers' Strongest Day" short story, her vacation time also ruined by the same trio.
Cain and Abel: The Cain to her older sister's Abel, Karen Nora Mathers. Both of them are the secretary to their respective organization's leader, with Westcott being the Big Bad and Mr. Woodman the closest thing to a Big Good.
Combat Pragmatist: Even though she expresses a slight dislike for it given her love for one-on-one duels, Ellen's not above teaming up with Jessica to bring down Mana under Westcott's orders.
Didn't See That Coming: After defeating Tohka in a one-on-one match, she did not expect Shido to activate his powers and summon Sandalphon by himself, but is pleased nonetheless, suggesting that she'd capture both him and Tohka.
The Dragon: Towards Westcott. There is not a single thing she will do without his approval.
Instant Armor: She's able to call forth her Combat Realizer outfit when engaging a Spirit, a privilege made possible by DEM's cutting edge technology. Origami post-Face-Heel Turn can also conjure her CR unit to fight Tohka, Miku and the Yamai twins.
Laughably Evil: Sorta. Despite she's the most talented Wizard, as well one of Wescott's most loyal follower, she's often subjected into Ai, Mai and Mii's antics during Yamai Tempest arc and Ellen Mathers' Strongest Day shorts.
Narcissist: She believes that she's invincible, claiming no one can defeat her.
Pride: She never stops claiming herself as the world's strongest Wizard, no matter the condition it is.
Psycho for Hire: She enjoys fighting with stronger opponent (particularly Spirits), while at the same time she wants to satisfy her superior's ambition.
Psycho Supporter: Again, towards Wescott. She's willing to do everything to realize her boss' ambitions, even if it means involving innocent lives in the process.
Purple Eyes: One of the few characters to have purple eyes, and she's one of the few humans capable of outmatching a Spirit.
Red Oni, Blue Oni: The boastful and arrogant Red to her older sister Karen's calm and collected Blue.
Resistance Is Futile: Suggests that she'd rather capture Tohka, and later Shido, without any resistance on their part.
Smug Super: She has the habit of looking down on Spirits, particularly Tohka, because she has the power and skill to subdue them very quickly. It's taken to its logical conclusion when she confronts Tohka in her Inverse Form, where her skills are no match for the Superpowered Evil Side's brute strength. She shows her arrogance again in Volume 10 when she warns Kotori and the Fraxinus' crew to not underestimate the power of herself and her own personal airship, the Goetia.
The Sociopath: Aside for her Blood Knight tendencies, she has no qualms about killing anyone who gets in her and Westcott's way, whether they be enemy or ally.
Sore Loser: Even though she's capable of curbstomping Tohka, she doesn't want to accept her losses when her first effort to kidnap Tohka failed. This also overlaps with Never My Fault, given she'd rather blame it all on others than to assume responsibility for her blunder.
Super Soldier: The most powerful within a squad of soldiers who underwent augmentations to be able to fight on par with Spirits.
Undying Loyalty: Once again, towards Westcott. No matter what happens, she never stops showing her pride, joy and loyalty to him.
Villain Teleportation: When she retreats along with Westcott after the appearance of Inverse Form Tohka, she uses her Wizard powers to warp away the both of them to safety.
Worf Had the Flu: She invokes this in regard to her fight against the newly-spawned Inverse Form Tohka, as she had been injured earlier on by Origami and thus wasn't fighting at her fullest, her wound even opening up during said fight.
World's Strongest Man: Stated repeatedly by the narrative and herself to be the strongest Wizard in existence, and demonstrated by her effortless handling of Tohka.
Worthy Opponent: Praises Origami in Volume 7 for being the second person to be able to wound her.
The leader of the DEM squad transferred to the AST as part of a secret mission to capture Tohka Yatogami (codename "Princess") and Shido Itsuka. She's also one of the strongest Wizards in the world, callsign Adeptus 3. Killed in combat by Mana Takamiya by the end of Volume 7.
Alas, Poor Villain: Her death is meant to expose the delusion of loyalty most DEM Wizards have towards Westcott, who treats them like pawns on a chessboard. Even Mana angrily lampshades this.
Always Second Best: She obstinately refuses to admit that Mana's skills as a Wizard are superior, and claims that the callsign "Adeptus 2" should've been hers.
Attack! Attack! Attack!: Even when she's outmatched by Mana and her own body is starting to wear down due to the Scarlet Licorice's severe strain, she still tries to shoot her opponent, forcing Mana to Mercy Kill Jessica.
Ax-Crazy: She's just as much of a nutjob as Ellen in battle, being previously a torturer before becoming a Wizard. But when she gets to pilot the Scarlet Licorice, she channels too much magic energy through her brain, making her barely able to utter anything other than crazed laughters or calling Mana's name repeatedly when the latter arrives on the battlefield. For comparison, Origami was able to pilot a similar prototype (and a flawed one at that) without suffering psychological breakdown.
The Berserker: When outfitted with the Scarlet Licorice, Jessica discards what little rationality she has and starts unleashing an endless barrage of attacks towards Mana. This comes back to bite her in the ass once her body can no longer sustain the severe strain imposed upon her by her CR unit.
Blood from the Mouth / Tears of Blood: After piloting the Scarlet Licorice for too long, blood starts coming out from her mouth and eyes, indicating just how drastic the strain on her body is.
Evil Redhead: Dark red hair, and one the few characters in story who are completely off their rockers. Not only is she a sultry woman with a penchant for violence, she also has admitted to killing people throughout her career as a Wizard.
A mysterious entity who gave Kotori and Miku their Spirit powers, as well as told Kurumi about Shido. Its appearance and motives are unknown.
Awesomeness by Analysis: Throughout its fight against Origami, who travelled back in time as a Spirit via Kurumi's powers, Phantom remains calm and correctly guesses that Kurumi helped Origami through the use of the Twelfth Bullet since Phantom has had yet to give away Metatron at that point in time.
A Form You Are Comfortable With: In volume 11, The Phantom appears to Shidou as Rinne (an Original Generation character from the first PS3 game). This could also explain why Origami saw and heard that the Phantom looked and sounded like someone she knows (specifically, her description of Phantom's appearance is of a completely different person.)
Blue and Orange Morality: Phantom seems to evaluate a person based on their potential as Spirits, as it outright states to an Origami-turned-Metatron that it would never pass up an opportunity to find such a powerful vessel for the Sephira Crystal.
Code Name: "Phantom" is actually a code name that Ratatoskr has given it for the time being.
Cryptic Conversation: When Shido is knocked unconscious after his first encounter with Tohka, he gets transferred aboard the Fraxinus, but not before hearing a garbled voice.
Phantom: Finally, we meet again. I'm so glad, but just wait. Just a little while longer. I won't ever let you go again. I won't ever be wrong again. Soon.
The Heavy: While definitely she's not a bad person, she's responsible for every single event of every arc of the series, albeit indirectly.
Literal Genie: Twice has Phantom appeared before a human to grant them Spirit powers some time before the story, and each time was in response to their anguished wish, for better or worse: for Kotori, it was her desire to stop being a crybaby; in Miku's case, she came to hate humanity (especially men) and despaired over the loss of her voice. A third time happens when Origami wishes for greater power in order to defeat the Spirits.
Power Crystal: It's revealed in Volume 8 that Phantom granted Kotori and Miku their Spirit powers by giving them each a small gem known as a Sephira Crystal. She also gives Origami one in Volume 10.
Samus Is a Girl: In volume 10, Origami's attacks strip away the noise concealing Phantom's appearance, allowing her to hear the latter's voice, which apparently reminds Origami of someone familiar. While she was blinded by the same attack, Origami could faintly discern Phantom as a woman with long hair.
Walking Spoiler: This mysterious entity's underlying actions are actually vital to the story, given the basic premise of sealing the Spirits wouldn't actually be feasible without it giving Spirit powers to key characters.
Ambiguously Bi: Ai, Mai and Mii have heard rumours about him "swinging both ways". Between his unnervingly chummy attitude with Shido and his obsession with dating sim girls, the cloud thickens. In Volume 8, however, when Natsumi shapeshifted into Shido and made a move on him, Hiroto was very disturbed.
Bromantic Foil: He gets very chummy with Shido, although most of the time it's just to boast how his relationship with his 2D girlfriend is going.
Demoted to Extra: While he never had much presence in the first season, he's almost never seen at all in season 2, and barely has any speaking roles when he is seen.
The eponymous character originating in Date A Live: Rinne Utopia, Rinne Sonogami is Shido's childhood friend, whom she goes to the Itsuka household every morning to wake him up and prepare his lunch.
Canon Immigrant: She makes her first novel appearance in the 11th volume. However, it is merely a form that the Phantom takes on to communicate with Shidou.
Childhood Friend: A traditional depiction of one for Shido, and little else is known. At least, until her story arc reveals that she's actually a Spirit who created a "Groundhog Day" Loop to save Shido after he got accidentally killed by an enraged Tohka, slipping into Shido's world as his Forgotten Childhood Friend at the same time.
Code Name: "Ruler", attributed to her Spirit Form.
Curtains Match the Window: Pink hair with a darker shade for her eyes. It's averted for her Spirit form, though, seeing her eyes glow red.
Determinator: She'll do anything for Shidou, literally anything. Lampshaded in Rinne Bathtime, where she said that she will do and become anything for Shidou with a straight face, Origami is even amazed by her words when she hears it directly from Rinne's mouth and that's saying something.
Harem Nanny: She takes this role quickly after she appears.
I Want My Beloved to Be Happy: To Shido, in any route that isn't hers. She'd be quite happy if Shido chose her, but at the same time wouldn't mind if he found happiness with the other girls.
Rinne: If Shido wants me, then I'll gladly give my everything to him. To become his lover, kiss him, have sex with him, marry him, give birth to as many babies as he wants, grow old together with him. But, even if Shido chooses someone other than me, I won't mind. If Shido thinks to marry Tobiichi-san, I'll bless him with all my heart. Of course, it also applies for other person as well. Even if Shido chooses Tohka-chan, Kotori-chan, Yoshino-chan or perhaps someone that I don't know. Of course, I don't mind if he doesn't choose to be with anyone, or even if he chooses everyone I'll support his wish. I'll do anything for Shido's happiness. If Shido wishes it, I'll grant any of his wish. I don't mind becoming his childhood friend, his lover, his wife, his younger sister, his older sister, his mother, his daughter, his superior, his subordinate, his enemy, his nemesis or even someone unrelated to him. As long as Shido is happy, I'm satisfied....Oh sorry, it seems I got too worked up by myself. But it is true that I don't mind whoever Shido chooses.
Meaningful Name: Her first name (凜祢) is a play on word with 輪廻 (also read as "Rinne"), a Japanese term of Samsara, the cycle of reincarnation or rebirth in several South Asian religions. Considering what kind of power she has, this is not surprising.
Rapunzel Hair: As Ruler, her locks are around waist-length, and one braid even reaches to her knees.
Ret Gone: The true ending of the game where Shido gets his powers back, while Rinne disappears.
Story Breaker Power: Her mana density is said to be equal to the First Spirit, and indeed if she would lose control of her power, the whole of Japan would be destroyed. She also managed to defeat Tohka, Yoshino, Kotori and Kurumi (and Origami) all at once.
Walking Spoiler: Her Ruler form shows up whenever Shido reaches a Bad Ending that isn't Kurumi's, triggering a Reset Button in the process, and is integral to the climax of Rinne's own route. Also, her eyes have whitened pupils, which is a sign of Spirit powers. Even her first light novel appearance is not what it seems, as it's only a form Phantom adopts in Volume 11 to communicate with Shido.
Yandere: In order to restart the world, and prevent his death, she murders Shido. This occurs as one of the bad ending endings in each of the other heroine's endings. Her power, called Eden, allows her to create and manipulate her world so that she can keep Shido alive no matter how many resets it takes. Unfortunately the key to resetting Eden is Shido's death in that reset.
An original character made for Date A Live: Arusu Install. While testing out the new game called "My Little Shido 2" developed by the Fraxinus's crew, Shido gets trapped in the virtual world after meeting her since the characters inside the game are based on the people Shido has met.
