The story is set in an alternate Earth where phenomena, known by the generic term "Spacequakes", occur. The first of these spacequakes devastated Eurasia thirty years before the time the story takes place, claiming 150 million lives. The protagonist, an Ordinary High-School Student by the name of Shido Itsuka, lives in a world where these disasters are common place. Schools regularly have drills in case of a spacequake, evacuations are done swiftly, and a group known as the JSDF disaster response team rebuilds the destroyed areas impossibly quickly. However things have gotten strange lately for Shido, the spacequakes that slowed down to a halt have suddenly appeared once again with terrifying frequency; and they all seem to be centered around where Shido lived...After a confusing series of events, Shido soon learns that all is not what it appears in the world. He discovers that the spacequakes aren't natural disasters, they are caused by beings, known as"Spirits", being forcibly sucked into this world from their own; and it also turns out that they happen to be top class Bishojo as well. He also finds out his little sister, Kotori, is a sadistic commander of a Spirit Response force, Ratatoskr, whose goal is to capture the Spirits without harming them. Unfortunately there is anothergroup called the AST (Anti-Spirit Team) who feel that simply killing them is the best solution. Shido, being the kindhearted hero he is, decides to use any alternative to save the Spirits since killing them seemed wrong (despite the fact they seem to cause mass destruction wherever ever they go). And it turns out that there is a way to save the Spirits without hurting them, the Spirits are able to lose their powers and live amongst normal people if Shido manages to... make them fall in love with him? As his sister Kotori bluntly lays it out for him, "Since it's like this, just go date her, and make the spirit fall for you!"And so yet another hero is created!Date A Live (デート・ア・ライブ) is a Japanese Light Novel series written by Tachibana Koushi(橘公司), with illustrations by Tsunako(つなこ), published by Fujimi Shobo under their Fujimi Fantasia Bunko label. The novel was first published in March 2011. Three manga adaptations were published: Date A Live (which follows the original novels, and got Cut Short), Date Ast Like (a Yuri spinoff involving Origami, with a girl from the AST called Mikie as the main character), and Date A Origami (a 4-koma which focuses on the romantic comedy aspect of the series). An anime adaptation was announced for the Spring 2013 Anime season. At the end of the last episode, a second season was announced. And here's a small trailer for the second season. At the end of the Second Season, a film adaptation was announced.The Light Novel currently consists of ten volumesnote for some reason, the word orders of the English and Japanese titles as printed on the LN covers are inconsistent:
All Your Powers Combined: Volume 7 reveals that Shido can use some of the powers from the Spirits he kisses.Just like a certain protagonist. While Volume 4 implied it and Volume 5 confirmed it, Volume 7 outright shows him using multiple Angels at the same time, for the first time.
Alternate Universe: The setting is basically Earth, with a history of a spacequake killing 150 million people 30 years before the start of the series. Depending on when said spacequake was, it may count as Alternate History as well.
Animation Bump: The second season of the anime has a noticeable increase in animation fluidity, especially during aerial battles like the Fraxinus's ship-to-ship combat versus the Arbatel, and Origami's standoff against Bailey and her DEM team (Bandersnatchs included).
Shido learned not to kiss another girl in front of Tohka. Which makes his job of sealing Spirits all the more difficult, but better that than having Tohka gain back her powers because she's that angry. Hurting Shido in front of Tohka is even worse. See Roaring Rampage of Revenge. And Superpowered Evil Side.
Tohka and Yoshino do this again in Volume 4/episode 12, distracting Origami long enough for Shido to seal Kotori's Spirit powers.
In Volume 7, we have Miku coming to Shido's rescue when he's trapped by some Wizards while trying to rescue Tohka. And later on, when Tohka loses control of herself and attacks them, Yoshino and the Yamai twins come to help.
Big "NO!": Shido lets one out when he's forced to cross-dress as a girl and Origami takes a lot of pictures of him as a result in episode 5 of season 2.
Blank White Eyes: Several characters will show these throughout the anime adaptation, be it for embarrassment or shock. Miku combines this with Color Failure upon discovering "Shiori"'s true gender.
Breather Episode: Episode 6 is original to the anime adaptation and far sillier than the rest of the series. Doubles as a Hot Springs Episode. Except they only get to the hot springs a a few minutes before the end of the episode.
Break the Cutie: Happens to Tohka and Origami when they think Shido has been killed by the latter.
Yoshino also. She created the Yoshinon personality to limit her own power so she wouldn't hurt anyone. And yet the AST still indiscriminately attack her. In fact Yoshino would easily have ended up like Kurumi if not for Yoshinon.
Poor Miku. After she refused to sleep with a TV producer, false scandals about her popped up and ruined her Idol Singer career, and her fans (over 90% of them are males) turned against her. And on top of that, she lost her voice due to all the stress. For someone whose only talent was singing, it was as if she lost everything. No wonder she hates men so much.
Can't Stay Normal: Type 2. Every volume brings a new threat that can't be thwarted without their powers.
Nerf: What happens when they do use their powers after having them sealed. Specifically, they seem to have a partially powered state where they are weaker and get a sort of partial Astral Dress. The difference being that their powers will flow back to Shido when they calm down, while if they take back all their power Shido has to kiss them again. We've only seen it with Tohka, who gets the skirt of her Astral Dress combined with her school uniform. However, Tohka duels Origami's AST squad without a problem in the low power state. Later, she gets owned by Ellen in the same mode however.
Even the Wizards handpicked by DEM wasn't immune to this either, as Ellen would attest in Volume 9.
Calling Your Attacks: The Spirits have a tendency to shout out the names of their finishing moves before they use them. As if shouting out the names of their Angels every time they summon them wasn't enough already...
Casual Danger Dialog: A variation as the communicators aren't fighting. During Shido's first encounter with Tohka, they do small talk with one another as they sit in place...all while the AST are shooting at them, unable to hit thanks to a force field from Tohka.
Chick Magnet: It's Shido's job description. Ironically, he's fairly bad at it. Kotori says this when Tohka appears asks Shido to take her on the date he asked for and Kotori and Reine happen to see them together in a restaurant.
Kotori: If that was the case, then onii-chan would be going out with a normal girl. If you ask me whether that or a Spirit silentlynote It's implied that it was thought to be impossible for Spirits to appear without a spacequake appearing is more likely... then by a narrow margin it would be the latter.
Then again, considering how quickly he got Tohka to warm up to him, and what he did for Miku in Volume 7, considering that she gave him much more help than he gave her, he may actually be much more competent in this department than Kotori claims he is.
Child Soldiers: A lot of the AST members, since the AST usually takes in those whose parents are dead. Usually killed by the Spirits.
Christmas Cake: Tamae, Shido's homeroom teacher. Reine would fit also, although it doesn't seem to bother her. Ryouko, Origami's superior is also this.
Circling Birdies: Happens to Tohka in episode 2 of second season, after she got hit by trash can thrice. Only the star or birds replaced with Yoshinons.
Cliff Hanger: One occurs in episode 6 of season 2, when Origami gets hit by a barrage of missiles fired from Bailey's DEM team, starts bleeding, and several bandersnatch androids show up behind her as reinforcements for Bailey.
Clingy Jealous Girl: Both Tohka and Origami towards Shido. Later on, the Yamai twin Spirits join in.
Subverted with Miku; while she's far clingier than the rest of the girls, she's far from being jealous. Ever. In fact, she doesn't even mind Shido having a harem. Though when she calls Shido "darling", Tohka, Yoshino, and the Yamai twins get a little jealous about it, and attempt to have him explain that definition. Kotori pokes fun at him meanwhile.
Close-Call Haircut: Shido gets two from Tohka in their second meeting at Raizen high when she was less than satisfied with some of his answers. The walls and buildings behind him don't fare as well.
Code Name: The AST and the DEM assign these towards the Spirits. "Princess" for Tohka, "Hermit" for Yoshino, "Nightmare" for Kurumi, "Efreet" for Kotori, "Berserk" for the Yamai twins, "Diva" for Miku, "Witch" for Natsumi, "Angel" for Origami.
Shido whites out in episode 13 after Origami does exactly what he asks her to do: stand on all four like a dog and act like one, even taking Shido's belt off to use it as a collar.
Miku is subjected to this in episode 7 of second season, after poking Shido's crotch and learned that he's crossdressing to get her attention after all.
Conservation of Ninjutsu: The few bandersnatch that attack Tohka and Shido in episode 4 of season 2 give them some trouble. Later, when several dozens of them are released, the Yamai twins destroy them fairly quickly.
Crazy-Prepared: Origami, in particular, her house. As in sentry guns are there to keep intruders out.
Ratatoskr itself is this. They had plans ready in case the Spirit Tohka snuck past them to date Shido... which they didn't even think was possible.
Murdoch out-crazy prepares them by having three satellites that he uses to Colony Drop one city just to take out Westcott. Though his plans failed, fans praise him for being that Crazy-Prepared for the situation.
one, the spirits are sentient and can be reasoned with. they can also have their powers sealed, reducing them into normal humans. so there really isn't much reason fighting them (unless they're psychos).
two, the AST has their rival organization: Ratatorsk, who decided to have someone date these spirits to submission, since they conveniently all happen to be girls. This is because their leader is also sort of one, and had her powers sealed as well.
Kotori after having to see Shido almost die again thanks to crossing a five meter barrier that would kill anyone approaching it. Interestingly enough, she didn't react at all the first time...note If Shido used his Healing Factor while crossing said barrier, he would be instantly frozen, so to cross the barrier to get to Yoshino he couldn't use his power, meaning he had a real chance of getting Killed Off for Real.
Yoshino after Shido manages to get through said barrier to hand her Yoshinon.
Kaguya and Yuzuru in episode 4 after Shido helps them to realize they're Not So Different.
Crystal Ball Scheduling: In episode 1 of season 2, Tohka and Yoshino are watching a soap opera while Shido says he's going out to shop for lunch ingredients. In the tv show the girls are watching, a man is seen packing a suitcase and telling his wife he's leaving her because he's tired of her. Tohka then goes to Shido's room with the intention of cleaning it, only to accidentally bump a suitcase, and sees it packed full of clothing. She then immediately recalls the soap opera from earlier, and fears he's secretly doing the same thing, and starts becoming incredibly unhappy. Later Tohka watches more of the soap opera, and the man is seen with another woman, who says his wife doesn't suspect a thing, and later leaves his wife at the train station with the other woman. Tohka once again thinks he's cheating on her, particularly as he took the suitcase with him this time, and once again is meeting up with Origami, by a train station no less.
Spirits versus, well anything that's not a Spirit really. Unless it's a very powerful Wizard from the DEM who can fight as well as them, if not better. Like Ellen.
Kotori delivers one to Kurumi in episode 10. She also likely would have killed her had Shido not stopped her at the last second.
In episode 4 of season 2, Kyouhei is so Dangerously Genre Savvy during the fight with the DEM ship that the latter is unable to land any direct hits on them after their first sneak attack. He also utilizes his abilities to damage their ship and force them to retreat.
Tohka suffers one as well against Ellen, who easily defeats her and was about to kidnap her right in front of Shido. Until he has a Traumatic Superpower Awakening and summons Sandalphon, Tohka's sword.
Bailey suffers one from Mana in episode 7 of season 2. The latter uses the Fraxinus's Wave Motion Gun to destroy the former's bandersnatch androids, and then defeats Bailey in about five seconds. After Mana knocks her out, she tosses her back to Bailey's underlings, who then flee the scene.
Cycle of Revenge: Spirit shows up on Earth, a huge calamity happens in a particular area. The survivor of said calamity then wants revenge to the Spirit who killed that person's parents or loved ones. Spirit (may or may not have to be the same Spirit) then gets dragged on by the revenge of said person and tries to defend herself from attacks. In case you haven't noticed, this is how Origami deals with Spirits with Tohka and Yoshino just trying to defend themselves.
Darkest Hour: Episode 7 of season 2/Chapter 5 of Volume 7. Tohka has been kidnapped by Ellen, and several of the other spirits that Shido sealed, as well as Kotori's crew have been brainwashed by Miku. Shido is at a complete loss as to how to solve this issue, until Kurumi shows up and offers him her help.
Dark Horse Victory: In Volume 4/Episode 11, as part of Shido's Training from Hell, Tohka, Origami and Yoshino are to excite Shido as much possible while they select swimsuits; the one who makes his heart beat the fastest wins a date with him. Both Tohka and Origami spend much of the time trying to outdo each other, only for Yoshino (who was stuck in the changing room all this while) to win in the end.
Date Peepers: Origami follows Shido and Tohka around on their date in Volume 1/Episode 3.
Dating Sim: How the crew aboard the Fraxinus deals with the process of decision making for Shido to date the Spirits. This is even how Shido is trained by Ratatoskr to prepare himself mentally to go on dates with the Spirits.
Death from Above: Kotori, while brainwashed by Miku, was nearly ready to fire her ship's Wave Motion Gun on the building below where Shido was at (along with hundreds of Miku's fans, but apparently they didn't matter). However, she's stopped with a quick knockout by Mana, who was sleeping at the time when the Fraxinus bridge crew heard Miku's Hypno Ray music, and wasn't under Miku's influence as a result.
Death Is Cheap: For Shido and for Kurumi. Also true for Kotori, whose Efreet powers are sealed inside Shido.
More of Healing Factor for Shido and Kotori, but they're treated as dead anyway before it kicks in.
Declaration of Protection: Shido essentially does this for every spirit he meets and is able to seal. Miku is skeptical of this initially however.
Despair Event Horizon: Tohka crosses this when the former decides to try to stay in this world... and then Shido gets shot by Origami. She thinks "the world had chosen to reject her in the cruelest way possible". Thankfully, Shido turns out to still be alive. And again in Volume 7, when Ellen pierces Shido's chest in front of her, leading her to tap into her Superpowered Evil Side.
And then Origami follows Tohka's example in Volume 10 after realized that she's responsible for her parent's death.
Did I Say That Out Loud: While Shido is showing Kurumi around school, three options for him pop up on the screen on the Fraxinus, one of which is asking what panties she's wearing today. Kyouhei immediately suggests that line, and then when he gives his perverted reason, Kotori has him dragged out of there, and then says that very line. Shido immediately starts to ask Kurumi that (before he realized what he just asked her), and Kotori also realizes she was broadcasting to him.
The punishments Shido has to endure whenever he screws up in the training Ratatoskr gives him certainly qualify.
When Kurumi sees four random guys shooting at a helpless kitten with airsoft guns, she decides to join in on the fun, but modifies the rules slightly. When Shido finds her later, it turns out her modified rules was to shoot the men with her magical gun.
At the end of Volume 4/episode 12, Kotori asks if what Shido said to her was true earlier. He reaffirms that he loves her...as a sister, promptly her to deliver a flying kick to him in response. Earlier in the episode it also happens in some ImagineSpots Kyouhei has, where he imagines the scenarios Shido is in with Kotori where she beats him up for various things.
Elemental Powers: Each Spirit has their own unique elemental abilities of which they can control at will (with the exception of Natsumi).
Tohka is a rather interesting case because it's not really specified what element she actually controls. She appears to be using Pure MagicalEnergy instead of an element.
Excuse Plot: The plot is basically: To save the world, date girls. Yes.
Exotic Eye Designs: Anyone with Spirit powers has whitened pupils. This of course includes Spirits themselves. Kurumi seems to be an exception at first, but when she uses Spirit powers it sometimes shows (albeit not in her left clock eye). The original Kurumi also has the white pupil all the time.
Eye Scream: Mana does this to Kurumi in the beginning of episode 9 of the anime, as evidenced by the reflection in her eye before getting stabbed.
The illustrations in each volume of the light novels include one depicting the Spirit(s) on the volume cover with their Astral Dresses taken off, leaving them only with underwear (if any).
The 5th novel stands out to the point that you think someone got told to ramp it up a bit. It takes place on a school trip to the beach and features the Stripperiffic Yamai twins trying to seduce Shido, so there is far more of this than the other volumes.
First Kiss: At the end of the first volume no less. Though it was true only for Tohka and not Shido, who had sealed Kotori's powers via the same way five years prior.
Food As Bribe: When Reine tells Shido in episode 12 that Kotori's feelings for him were already at max level, Kotori claims it must have been a fluke. When Reine tries to clarify that it isn't, Kotori then points at her and mentions a dessert. Reine immediately claims the numbers must have been an error.
Friendly Tickle Torture: When Kotori (wearing white ribbons) violently wakes up Shido, he says that if he doesn't get another ten minutes of sleep, he'll be infected by a virus which will cause him to tickle her uncontrollably (also known as theT-Virus). He then puts on a scary face, causing her to run out of the room.
Godzilla Threshold: The appearance of a spirit warrants this, though the different human organizations have different ways of handling said spirits:
The AST/DEM Wizards attempt to kill the Spirits, usually by shooting them. For the most part though, it doesn't seem very effective, at least when shown on screen.
The Ratatoskr organization, on the other hand, utilizes a more unconventional method; have Shido talk to the Spirits, take them out on dates, and seal their powers with a kiss. As evidenced by Tohka, Yoshino, and Kotori, this seems to have a better success rate, though it's not always easy for them either, particularly because the AST gets involved regardless.
Gory Discretion Shot: Used a fair bit in the anime, which seems to target a younger demographic than the light novels. While not a particularly violent series, basically nothing is shown. Blood splatters are basically it. The blood is redat least.
Shido getting shot is basically a Freeze-Frame Bonus to even see his body falling, and he appears unhurt on the ground (after getting shot with the equivalent of an anti-tank round). Similarly, Shido appears unharmed after passing through Yoshino's "barrage of shotgun shells" barrier; in the novel, he was unrecognizable until the Healing Factor kicked in.
Kurumi gets led into an alleyway by three thugs (more like sheled them in, though) and... we see a truck run over a can of tomato juice. Similarly, when Mana kills Kurumi, the entire scene is covered in heavy shadows (and she wearsred and black) so nothing is really visible before the camera cuts to a reaction shot of Shido watching.
Go Through Me: Shido does this in Volume 4/Episode 10 in an attempt to stop Kotori from blasting Kurumi into oblivion. She regains her sanity at the last second and just barely adjusts her aim to avoid hitting him.
He does it again in Episode 12, this time to prevent Origami from shooting Kotori.
Hair Decorations: A number of them (Kotori, Tohka, Origami, Kurumi, Miku), but special mention goes to Kotori, whose personality depends on the colour of her ribbons.
Harem Seeker: Shido is an unwilling one, since Ratatoskr pretty much forced the job on him. Naturally, the harem he gets as a result is just as unwanted. It's made worse as Shido originally thought Tohka was the only Spirit, and even then he wasn't too big on the idea of having to date her.
Healing Factor: As put by Kotori, Shido is starting a New Game+ thanks to his healing factor. This is because he kissed Kotori back when they were kids and her powers are currently sealed within Shido.
Hero Insurance: Shido seems to have full coverage courtesy of the Ratatoskr, who shows up to fix just about any damage caused by the spirits. For example, during the OVA, Tohka destroys several arcade machines. Each time she does, some men show up and replace said destroyed machines with brand new ones.
Hoist by His Own Petard: Shido tries to make Origami hate him in the OVA by attempting to make her do humiliating things such as changing into a school swimsuit with some dog ears and tail, then get on all fours. She promptly does that, stating there was a shop nearby and even uses his belt as a leash. He also tries to say he's a pervert, but she doesn't seem to lose interest despite all that, and unfortunately nothing seems to faze her. Kotori suggests he break up with her, only to accidentally say it to Tohka who was calling him at that exact moment. Tohka's mood drastically shifts, forcing him to focus attention on her, and when he says he doesn't hate her, he forgot he was also calling Origami at the same time, who also heard everything he told Tohka. In the end, his plan only ends up making Origami like him even more.
Hot Springs Episode: In Volume 5. However, the twist is that Origamitries peeking at the boys' side while the rest of the boys (Shido's at the girls side, long story) try peeking at the girls side.
Episode 6 of the anime, though the bulk of it consists of the trip to the hot springs rather than the hot springs itself.
I Am Your Opponent: Tohka declares to Origami that she'll keep her busy while Shido attempts to reach out to Yoshino.
Kotori: If we want a solution to the spacequakes without using force, then we have to persuade the Spirit right?
Shido: That seems right.
Kotori: For that, wouldn't it be quickest to make the Spirit come to like this world? Oh, this world is so wonderful~, if they become like that, then even a Spirit wouldn't randomly go on a rampage.
Shido: I see.
Kotori: Thus, well, isn't it often said? That if you fall in love then the entire world seems beautiful. —And so, date her, and make the Spirit fall for you!
Shido: No, there's something wrong with that logic.
The Dating Sims that Kotori makes Shido play are also full of this. This is one of the reasons why it counts as Training from Hell for him (the other being the punishments for failing).
Instant Armor: Extremely powerful Wizards like Ellen are able to conjure their Combat Realizer outfits in an instant, unlike the regular AST members. Origami displays the same ability upon engaging the sealed Spirits in Volume 10, as part of the new equipment she got from allying herself with Westcott.
Intimate Healing: While exploring Miku's mansion for clues in episode 7 of season 2, Kurumi teases Shido about wearing a rather large bra she finds in the room. As she slowly advances and teases him with the notion of having him wear it, she trips and falls on top of him. He has a slight scrape on his face, which he says a little spit would be fine on it. Kurumi then proceeds to start licking his cheek.
In Episode 7 of Season 1 of the anime, Mana and Kotori are having an argument about Shido. They mention various things, which confuses Tohka and Yoshino. They think the two girls are talking about rice, and Yoshinon then mentions something about mixing the two together in a bowl to eat, and Tohka innocently asks Shido to put Kotori and Mana together. He immediately asks if she's trying to make him into a criminal.
Laser-Guided Amnesia: Endemic to the setting, with Shido and Kotori having significant holes in their past memories. Notably, the entity that gave Kotori her Efreet powers, Phantom, then proceeded to strip Shido and Kotori of their memories. While Kotori forgot only about the existence of said entity; Shido forgot a lot more. All the Spirits (that weren't known to be originally humans, anyway) have no memories of before that time and seem to have lost variable amounts of basic knowledge. Tohka seems to be the hardest hit, as she even lost her name, creating a lot of Fish out of Water situations (she didn't know what a (animal) fish was either, or that they swim, for that matter. She thought they were only food and an aquarium was a restaurant).
Deus Ex Machina (DEM) Industries, a corporation based in England, and the company that makes the Realizers. In Volume 5, DEM's managing director (Westcott) gets Origami's punishment for borrowing a prototype without permission changed from "dishonorable discharge" to "2 months house arrest", which means she is basically taken off from active duty and given a vacation. They also get the school's field trip changed to a small, isolated island as part of their plan to kidnap Tohka.
Asgard Electronics, the company backing Ratatoskr, may also fit here. It's implied that they were able to come up with fairly strong backgrounds for the sealed Spirits.
Meido: Origami dresses as one when Shido goes to her house because she overheard him saying that maid costumes are better than nurse costumes. Also, we see quite a lot of them in Volume 6-7. Including a maid café.
Mike Nelson, Destroyer of Worlds: Most of the Spirits are unaware of the devastation their arrivals on Earth cause. When Tohka is told about the spacequakes, she is shocked and remorseful.
Mildly Military: The AST seem to function like this. They seem to be able to have a normal life outside of their military duties, and always seem to act independently from other military forces.
Mind Control Music: Miku uses this on the audience in episode 7 of season 2 after losing to Shido in the contest they bet on. Unfortunately her hypno music also turns Yoshino, the Yamai girls, and even Kotori and much of her crew against him as well. Only Tohka seems unaffected, though it's because her ears were plugged up with the ear pieces they were using to help them during the concert, so she couldn't hear the music Miku used on them. Reine, at least one other member of Ratatoskr, and Mana are also unaffected due to not being around the bridge when the music affected the other crewmembers. Meanwhile Kyouhei doesn't seem to be affected by it either, but for obvious reasons he doesn't stop Kotori from attempting to fire on the stage below while under Miku's influence.
Moment Killer: Tohka does this at the end of episode 10 in season 2 when she comes to Miku's changing room to get her for an encore. Only to then find a naked Miku holding onto him, and calling him darling.
The anime opens with a space quake devastating central Asia, killing 150 million people. Then it cuts to the Panty Shot-lined wakeup call that Shido has to endure when Kotori has a hyper morning.
Shido's highly silly first date with Tohka ends with her deciding to stay in this world followed by him getting shot. In Volume 3, the very silly triple date sequence is interrupted by Kurumi shooting some people in an alley and then getting brutally murdered by Mana. Of course, Death Is Cheap for Kurumi, but...
The first half of episode 10 is a brutal fight between Efreet and Kurumi, followed by some exposition for Kotori. Then the last third or so of the episode is filled with Origami attempting to seduce Shido at the hospital, followed shortly by her revelation that her parents died in a fire which she blames on Efreet, who Shido just learned is Kotori.
Mundane Made Awesome: Ai loans her trusty tambourine to Tohka, which played like her loaning something like Excalibur.
Nice Job Breaking It, Hero: In episode 1 of season 2, Shido attempts to buy some kinako bread for Tohka to make her happy again after she suspected him of cheating on her with Origami. Unfortunately they can't find any, causing Kotori to wonder why they just happened to be all out of that particular bread in every bakery. Kyouhei then walks into the bridge with a large bag of kinako bread, stating he bought all of it to ensure they have enough to give to Tohka, but inadvertently caused the problem because of it.
Non-Lethal Warfare: AST vs Spirits. Justified in that the Spirits are Nigh Invulnerable, so they don't feel all that threatened and so don't fight back seriously either. Medical Realizers heal most injuries that happen fairly quickly (Origami mentions getting a broken arm healed overnight) This removes most of the consequences of the Child Soldiers. The AST members seem to be generally sane and well adjusted, or at least, their issues don't come from fighting.
Taken Up to Eleven in episode6. Again, justified since Ratatoskr's intention was only to stall the AST, not kill them.
Tohka and Shido's suitcase in episode 1 of season 2, when due to watching a soap opera, thinks he's secretly getting tired of her and is leaving her for Origami. The latter playing up that part doesn't help matters either, and Shido has to reassure her the suitcase was for their field trip next week and the lock was broken on it, and that he was taking it to get it fixed. And that he is definitely not leaving or getting tired of her.
In episode 4 of season 2, after he inadvertently seals Yuzuru and Kaguya (due to them kissing him at the same time with his eyes closed), both girls lose their spirit outfits, go completely naked, and then make it sound like he was a pervert to Tohka. The latter doesn't take it too well.
The Nudifier: Spirits' clothing (Astral Dress) are part of their powers. So if those powers are sealed..... This may be one of the few cases where this is Played for Drama rather than comedy or Fanservice, at least for some cases.
Parental Abandonment: Origami's parents were killed in a fire caused by a Spirit and Shido's mother (and by extension, Mana's) abandoned him for unknown reasons. He's currently adopted by the Itsuka's, in which both parents are currently abroad.
Pillow Fight: One occurs in episode 3 of season 2, though it isn't seen much aside from Ellen getting hit with one.
Power Parasite: Shido seals the Spirits' powers within himself when he kisses them. He latter learns how to access the powers himself.
Psycho For Hires: Most, if not all, DEM Wizards are trained to become Wescott's loyal fanatics who voluntarily obey what he says, while money may or may not be a secondary need. Best examples are Jessica and Ellen.
Rent-a-Zilla: Yoshino's Angel (Zadkiel) got a Kaijuupgrade in its second appearance in the anime, complete with Dutch Angle as it lifts it's head above the surrounding buildings.
Rescue Arc: Volume 7 has Shido trying to save Tohka from the clutches of the DEM.
The Reveal: At the end of Volume 3/episode 9, where Kotori shows up as a Spirit, and canceled out a spacequake Kurumi attempted to cause.
At the end of episode 11, Origami sees Kotori as Efreet in some video footage shot during the battle with Kurumi.
Right Behind Me: In episode 8 of the anime, after Shido asks Kurumi out on a date, he has a Flash Back of being told by Kotori to ask her out. So he promises to make Kurumi fall in love with him, only for Origami to show up behind him and ask what he's talking about. The light novel has the same scene without the flashback.
Running Gag: The Ai, Mai, and Mii trio. The first would always bring up a subject during a certain situation (usually geared towards Shido and his actions) with the second supporting the first's statement with her own opinion. The latter then concludes the entire subject with her signature catchphrase "Gross!". Later changed to "That's so lame!" in the second season of the anime.
Selective Obliviousness: Shido claims he passed out shortly after Origami did in episode 10 while visiting her at the hospital. She then tells him that her parents died in a fire five years earlier caused by one of the spirits, which was also why she's a member of the AST and so intent on killing spirits. He just found out moments earlier that Kotori was a fire-based spirit, but chose not to say anything about it, particularly after her reveal.
At the end of Episode 12 of Season 1, Tohka asks Shido for a kiss. Although they're being spied on by the Ratatoskr, he follows through with it...only to end up kissing Yoshinon instead, who then, along with Yoshino, says "to be continued...sometime." Right after that, Season 2 was announced.
Episode 10 of Season 2 takes a different approach; after the climax is over, we are treated to Kurumi musing that her target isn't present, before fading away into the shadows. The last portion is dedicated to the resolution of Miku's case, but then a movie adaptation of Date A Live was announced.
Serious Business: Ratatoskr takes Shido's dates with girls very seriously. Since it's to save the world...
When Kotori tries to wake Shido up, he tries to get her to go away by saying that unless she lets him sleep for another ten minutes, he's going to give her the tickle hell virus. Otherwise known as the T-Virus.
In the anime, the first spacequake alarm has small buildings, trains and the like retracting into the ground for the obvious Neon Genesis Evangelion reference.
The spacequakes themselves in the anime, when observed very closely, bear a striking resemblance to a Subspace Bomb going off.
The poses Shido and Tohka make during their first encounter seem familiar.
Shido does it in episode 8 of the anime when he sees Tohka running outside looking for him while he's on a date with Origami. (And Tohka. And Kurumi.)
Split Personality: Kotori has one although it's more of her switching personalities more than anything else really. The best way to figure it out would be that she would be the nice little sister with her white ribbons, while she would be the sadistic commander if she's wearing her black ribbons.She has a third one when her 'Efreet' Spirit powers return. Yoshino has one as well (her puppet Yoshinon is the outspoken fellow while Yoshino herself is a shy girl).
The anime's first season opening shows the first 3 Spirits, and there are also previews for each main girl. They all spoil Kurumi's left eye, which is a big hint as to what her powers are.
The three girl silhouettes are also spoilers in themselves - Touka doesn't know very well what to do. Kotori is distant. Origami is lamenting. That's exactly how their personalities are.
Similarly, the second season's opening doesn't shy away from revealing Kotori's Spirit form from the get-go (doubles as Late-Arrival Spoiler), although the Yamai sisters and Miku's faces are not clearly shown. The same opening features the appearance of Isaac Westcott and Ellen Mira Mathers, the emerging villains of later volumes. Finally, the ending gives us a full shot of Tohka's Inverse Form, who only makes her formal introduction in the final episode.
Spoiler Title: Volume 10 is titled "Angel Tobiichi". Every single volume before it is named after the Spirit it focuses on, and Origami here is no exception.
Springtime for Hitler: Shido spends the first half of Episode 13 attempting to make Origami reject her love for him in the worst ways possible (public humiliation, admitting he's a lolicon/siscon, etc.). Which fails spectacularly since Origami... isbeingOrigami.
Stable Time Loop: Origami travels back in time and attempts to stop Phantom from killing her parents (under the presumption that it did it). In the ensuing chaos, she ended up causing the fire that killed her parents.
Strike Me Down with All of Your Hatred: Played straight but it's Shido who invokes this towards Origami. He then tells her that since she thinks it's Efreet who killed her parents, and that Shido currently has Efreet's powers thanks to him sealing Kotori, he goads her into killing him if that's what it takes to satisfy Origami's revenge. Origami doesn't go through with it.
In Volume 7, Tohka, after crossing the Despair Event Horizon, transforms into a darker version of herself, called Inverse Form; Westcott speculates that this the Spirits' natural form in the bordering dimension. It takes a kiss from Shido to bring her back.
Even, earlier, Kotori almost succumbed to this, as her Efreet personality is rather bloodthirsty, and she would have totally control had Shido's pleas not snapped her out of it.
In Volume 10, Origami, after being transformed into a Spirit by Phantom and going back in time to fight it, learns the truth about her parents' deaths. She does not take it well, and pulls a Despair Event Horizon similar to Tohka, darkening her Astral Dress and becoming a threat to everyone.
Suspiciously Specific Denial: In episode 5 of season 2, Shido has to cross-dress as a girl to approach Miku, who Does Not Like Men. While he fools the trio of girls Ai, Mai, and Mii, Tohka asks him what he's doing. When he tells her he has a reason for this and asks her to play along, she agrees, and says how nice it is to meet this woman who is totally not Shido. Origami isn't fooled either, but takes lots of pictures.
Take a Third Option: Shido is coerced into doing this when he learns that its the only option the humans have against Spirits, aside from shooting them or letting them kill more people by accident. In Volume 5, this is also what he does to the Yamai twins by letting them both live on, instead of just one of them.
Also what Origami tried against the blizzard dome Yoshino set up. It would have worked if not for Tohka's intervention.
During his date with Kotori in episode 11, all of the options he's given seems to go bad, and Kotori doesn't seem like she's having too much fun. So he then decides to throw away the earpiece used to communicate with the Ratatoskr, and instead just takes her out to an amusement park, which seems to work a lot better.
Talking Is a Free Action: During the Dating Sim choices Kotori gives her crew just 5 seconds to make their decisions, but after that the time taken for the crew to explain their choices and for Kotori to relay to Shido which option to choose both count.
Tempting Fate: In episode 1 of season 2, Shido takes Tohka out shopping after she accuses him of cheating on her with Origami. He takes her shopping with him, and promises to buy her as much kinako bread as she wants. However the first bakery is sold out, and Shido tries to reassure her that there are plenty of other bakeries, and they couldn't all possibly be sold out, only to find out they are all sold out. Kotori wonders why they just all happened to be sold out that day, with Reine suggesting maybe they had a sale. Kyouhei then immediately enters the bridge, commenting that he bought up all the kinako bread so that Tohka wouldn't go crazy, and inadvertently causing the problem.
That Came Out Wrong: In the OVA, Tohka tells her classmates about the wonderful date Shido took her out on. At first they think it's sweet, until she mentions things such as hitting and being in ecstasy, making it sound like they had sex. The naked picture she took and gave him that he accidentally loses in the class only reinforces their suspicions. He tries to tell them they were only at an arcade, but they won't let him explain, forcing him to run out of the classroom.
At the end of the first episode in season 2, Kurumi shows up again after having disappeared during the last few episodes of season 1, and says she needs to bide her time a little in order to save up power to use her last ability.
Kotori is seen talking to her superior at the end of episode 4 in season 2, regarding Shido's recent actions. She says if she has to, she would personally kill him.
Shido: Uh... For a bitch like you to walk on the same level as a human is so presumptuous. Err- get on your hands and knees- I said on your knees, bitch! Origami:[Goes on all fours] Shido: Arrrgh?!? Kotori: What?!? No way!
Three Timer Date: Thanks to Shido unable to say "no" to Tohka and Origami, he's going to have to date them plus Kurumi in Volume 3.
Happens to a random guy who was torturing a small kitten. Kurumi sees four men shooting at the kitten with airsoft guns, and she repays the favor to them by blasting them with a real gun. Shown more clearly in the anime, where the camera pans behind the unfortunate victim as she blasts holes in him.
Several volume covers blatantly spoil some big revelations that are included in the story. Volume 4's cover depicts Kotori in her Spirit form; Volume 7 has Tohka in her Inverse Form; Volume 9 has Natsumi's true form; Volume 10 has Origami in her newly-acquired Spirit form.
The preview at the end of the anime's first season gives away some key characters for Volumes 5 through 7, namely the Yamai sisters, Miku Izayoi, Westcott and his subordinate Ellen, and Tohka's Superpowered Evil Side.
Training from Hell: An unusual variation but still played straight in that Shido gets subjected to this by the Ratatoskr crew. If he makes a wrong choice whenever he goes to a date with a Spirit, well, see Butt Monkey up above.
Underdogs Never Lose: In Miku's arc during season 2, she makes a bet with Shido. If his school wins the festival event, he could seal her powers. But if her school wins, he becomes her slave and gives the power of the spirits he's sealed so far to her. When episode 7 begins, Miku's school wins the concert portion. She then begins to taunt Shido. stating the reason he lost was because he relied too much on his friends. Then it turns out Shido's school was voted the most popular due to their maid cafe. Miku understandably doesn't take this well.
Kurumi saves Shido multiple times during the Miku arc. Due to being out of options with his allies either brainwashed by Miku, or incapacitated, he's also forced to work with her in order to first get Miku out of his way, and later rescue Tohka.
Miku intervenes when Shido gets bogged down while attempting to locate Tohka in episode 9 of season 2. With her help, he's able to locate Tohka much faster, though Miku claims she's just helping him because she wants Tohka's spirit powers as well.
Well-Intentioned Extremist: The AST. Kurumi also; the reason she killed over 10000 people was to accumulate enough power so that she could go back 30 years in time to kill the first Spirit that caused the spacequake 30 years ago.
Wham Episode: Episode 3, when Origami takes a shot at Tohka, but Shido pushes her out of the way, just in time to get shot instead. What was supposed to be a light-hearted episode suddenly does a Mood Whiplash at that moment. Actually subverted because he gets better due to his Healing Factor.
The Kurumi arc plays this straighter since she's the first Spirit whose powers he fails to seal.
The Miku Truth arc become this with the introduction of Inverse Form.
Yoshino as well, but in a lighter shade. A rare subversion in the Shido admits it's a color that is "impossible to grow naturally".
Miku too, but in an even lighter shade.
Your Days Are Numbered: Mana only has 10 years left to live after undergoing a procedure to strengthen her body enough to fight on par with Spirits. She's also not the only one to have undergone the procedure.
You Killed My Parents: Origami says this to Kotori while she's in her spirit form Efreeth in episode 12. Which turns out to be The Reveal as well, since it causes Kotori to back off long enough for Origami to take flight again and activate her weapons again. Only, Kotori was not the Spirit that killed Origami's parents...
And then it turns out Origami herself killed her parents after thinking that Phantom was the one who did the deed. To say she went ballistic is an understatement.
Your Princess Is in Another Castle: It's revealed at the end of Volume 7 that she was trying to find the Second Spirit, who was supposedly imprisoned by the DEM, and was the only one who knew where the First Spirit (her actual target) was. She offered help to Shido in the hopes of finding the Second Spirit in the place where Tohka was imprisoned, but the Second Spirit was actually imprisoned elsewhere. At least she got a pat on the head from Shido.
Zettai Ryouiki: Kotori wears Grade S! Except for her Spirit form, sadly.
Some girls in Shido's school (including Tohka) wear Grade A. Even Origami who doesn't, wears one in her Meido uniform when Shido visits her house.
Some Spirits' Astral Dresses include this. Tohka and Kurumi wear this under their dresses, and the Yamai twins wear them too.
