Ashinaka High School. A unique school that is known for being built entirely on an island.Twenty Minutes into the Future, following a slightly Alternate History, Japan has become a technologically advanced land and one of the world's most flourishing countries. In Shizume City, clans serving individuals known as "Kings" have risen. The clansmen, empowered with the aura and the psychic powers of their Kings, fight one another in a struggle for power. The ever-growing rivalry between HOMRA, the Red Clan, and SCEPTER 4, the Blue Clan, escalates when a member of Homra is killed by an individual claiming to be the "Colorless King".Amidst all this, an energetic 17-year old student of Ashinaka High known as Yashiro Isana (or Shiro for short), finds himself chased by a bunch of shady guys, members of Homra. Just as he thinks he's saved by the timely intervention of Kuroh Yatogami, he somehow ends up with his sword pointed at his neck. And soon after, all display devices within the city begin to static - show a man who is unmistakably himself, identifying himself as the Colorless King...Written by GoRA, a team consisting of seven Light Novel authors, K is an original Fall 2012 Anime that premiered on October 4. The anime gained some notice by revealing almost no details about its plot, setting, or genre in promotional materials. It was quickly picked up by both Animax Asia and VIZ Media for simulcasting. A sequel was announced when the last episode aired. In May 2013, the sequel was confirmed to be a movie adaptation that will be released sometime in 2014.A prequel manga, K Memory Of Red, began serialization in Kodansha's Aria on May 2012. Another prequel manga, K - Stray Dog Story, began running in Koudansha's good! Afternoon on November 2012. Two Light Novels, called K Side:Blue and K Side:Red, were released in October and November 2012. These two were followed by K Side:Black & White, which was released in May 2013.K has also been picked up by VIZ Media and will be aired on their Neon Alley site with an English dub.Not to be confused with K-On!Tread carefully. Spoilers abound.
This anime provides examples of:
Accidental Truth: In Episode 2, Yashiro cooked up a fake story about his imaginary sick sister who's been hospitalized since a young age to garner sympathy from Kuroh and give himself ample time to escape. Then in Episode 11, it's revealed that he is Adolf K. Weismann, whose elder sister Claudia died in the war...
All There in the Manual: Due to a clever marketing ploy K has large chunks of background information and a bunch of characters' backstories provided via manga adapations, radio dramas, Drama CDs, and novels.
There is a war of words among fans as to whether or not the Sword of Damocles Yashiro summoned prior to getting rid of his amnesia and learning he was the Silver King was real or an illusion. It comes down to either Yashiro being able to use his abilities without remembering who he was, or Neko's illusions being arbitrarily powerful. Suffice it to say, there is so little said about the subject in-universe that the truth is muddled.
There's a blink-and-you'll miss it moment in the last episode that has incited quite a bit of debate: A black dog carrying a sword, running with a white cat carrying a parasol. While this is obviously Kuroh and Neko, it is unclear if it means Kuroh is a dog strain, which would come way out of left field, or if Neko was just using another illusion.
Is Neko a cat or a human? There's evidence pointing to both arguments. As a cat she can be held in Shiro's hand and sit on his shoulders without seemingly to put any kind of strain on him. She also behaves very much like a cat, and animals are known to have powers as well as humans. However when Munakata destroys her illusion she reverts back to a girl. Though there's also the theory of her being a legitimate shape-shifter in addition to holding illusion powers.
All of the above ambiguous situations have been resolved in side materials. Shiro came up with the plan to fool Munakata, but the Sword itself was Neko's illusion. The dog and cat at the end of the last episode was completely Neko's illusion as well, and Kuro has since been proven to be a normal clansman and not a Strain. Neko herself was born a girl with illusionary powers, but chose to live her life as a cat due to circumstances in her past.
Animal-Eared Headband: An elite faction of Gold Clansmen are known as the "Rabbits" because they all wear masks adorned with rabbit ears and even have small tufts of fur attached to the backs of their kimonos. In this case the unusual animal-inspired appearance is treated in a fairly serious manner instead of as a cute quirk.
Apocalyptic Log: Tatara Totsuka's video tape, which contains a declaration by "Shiro" that he is the Seventh King.
Armor Is Useless: Shown in K Side:Blue that armor is essentially worthless against psychic users. Even though the main character Takeru Kusuhara was equipped in riot gear including a large shield and a helmet, one of the criminal Strain he was facing easily slices his shield with a Magical Gesture as if it was made of butter.
Ass Pull: In-Universe, Yashiro had to rely on making things up to successfully escape from an almost certainly bloody death at the hands of Kuroh.
Asshole Victim: Despite seeming like an evil ruthless gang on the offset, the people HOMRA attacks (with the exception of Yashiro) are only those who deserve them - such as violent mafia goons.
Batman Gambit: In Episode 8, Yashiro manipulates Scepter 4 to his advantage through a phone call. Munakata, being clever as well, knew what Yashiro was up to and attempted to double-cross him - but Yashiro one-ups him as Kuroh catches it at the last second and Yashiro manipulates him again.
Battle Aura: All of the kings and some clan members have glowing auras that match their clan's color when using their psychic powers.
Battle in the Rain: Episode 7 has Scepter 4 cornering Shiro, Kuroh and Neko. Kuroh fights Reisi in the rain to give the others a chance to escape.
Big Damn Heroes: Kuroh Yatogami saved Yashiro Isana from the HOMRA thugs...and then immediately tried to kill him himself.
Bittersweet Ending: The evil Colorless King is ultimately killed, Totsuka's death is avenged, and Mikoto's Sword of Damocles is prevented from dropping. However, both Shiro and Mikoto are seemingly dead and the HOMRA clansmen have lost their King. Neko, however, does not believe that Shiro is dead, and she and Kuroh both leave in search of him.
A subtle version - the large-screened clearly Panasonic television in the city with a similar logo is named "anasona". And then there's the conspicuous "Starpucks Coffee" building shown in Episode 1.
In episode 3, an iPhone advert can be seen in the background... with an orange next to it.
Bond Creatures: The Dresden Slate is revealed to share its powers with the Kings only after establishing a psychic connection with them once their heartbeats are synchronized to its "pulse".
Bullet Dodges You: The 'bomb and umbrella' supposition, used to describe Kings in the novel K Side:Blue, states that no matter how many missiles or bullets are fired at The Chosen One, they would all miss him as if being deflected by a giant umbrella. But what if a nuclear bomb were to be dropped on their heads? Its power is such that, even if deflected, it'll still cause harm to The Chosen One. The answer is that fate itself won't allow the nuclear bomb to fall - it'll just hang there in the air, suspended by an invisible umbrella.
Cataclysm Backstory: The Kagutsu crater that is shown briefly in Episode 3 is revealed to have been one according to side materials. This incident, which was caused by the former Red King's Sword of Damocles dropping ten years before the story began, destroyed a large part of southern Kanto and killed over seven hundred thousand people, including the Red King himself. It was even (indirectly) responsible for the former Blue King's death as well.
Cerebus Rollercoaster: The first episode starts off fairly dramatically and ends on a rather tense note as Kuroh prepares to cut down Shiro for supposedly committing a murder. Then Episode 2 abruptly shifts the tone to comedic during the wacky chase scene between the main trio before the next episode returns the story to a sober tone as it introduces mounting tensions between the Red and Blue clans. Episode 4, however, immediately reverts back to a lighter and more humorous tone as Shiro attempts to prove his innocence to Kuroh, at least right before the ending suddenly changes the tone back to dramatic again. The tone continues shifting between comedy and drama right until the end of Episode 6 where it goes right back to being serious again, only this time it stays that way for subsequent episodes.
The Chosen Many: The seven Kings are all chosen by the Dresden Slate to receive great power and rule over others.
Cold-Blooded Torture: Revealed in the novel K Side:Red that Anna was tormented both physically and mentally as part of the experiments to get her to reach out to the Dresden Slate and become the Blue King, because suffering and pain enhances her sensory capabilities. She has no scars to show for it because she would simply get healed up by the experimenter in charge.
Color Motif: The colors of the known Kings and their clans seems to follow these motifs for the most part (red is violent/passionate, blue is calm/rational, gold is wealthy/prosperous).
Color Wash/Mood Lighting: The anime uses color filters extensively, most often using an Unnaturally Blue Lighting in most parts of the city but switching tints depending on the location (e.g. the HOMRA bar primarily uses deep red and orange colors while the school island uses some noticeable green filters).
Cool Airship: Adolf K. Weismann's airship, the Himmelreich. Apparently, it flew around the same routes over Japan for over sixty years until it started deviating and going in random directions for the anime storyline. Eventually, it comes crashing down in Episode 8 after the Silver King blows it up when the SCEPTER 4 helicopters attempt to apprehend him.
Saruhiko pulls this off against four members of HOMRA at the same time in Episode 3, although it isn't really shown how he did it.
Reisi vs Kuroh. The former didn't have to draw his sword or even use his powers to subdue latter, despite how much Reisi taunted Kuroh to draw his sword.
Mikoto against SCEPTER 4 (minus Reisi) in episode 9: he completely destroys Seri and her men in a single hit. They go down so fast it's not even funny.
The developers have stated multiple times in their twitter account that any non-King vs. King battle will end up like this, explaining the two examples above.
Cryptic Background Reference: The anime is loaded with these kinds of references, especially in the beginning. What exactly is a Sword of Damocles, a Weismann level, the Dresden Slate, or the Kagutsu Crater? Good luck figuring it out while watching because the anime won't properly explain these terms until much later, if at all.
Crystal Prison: SCEPTER 4's powers are shown to be capable of manifesting as cubic crystals in the novel K Side:Blue, which they can then be used to imprison the physical forms of other psychic weapons, such as an invisible bomb attack, and prevent them from functioning.
Death from Above: The Swords of Damocles are capable of demolishing entire cities and leaving gigantic craters in their wake from the ensuing explosion if they ever fall to the ground. In fact, the previous Red King is said to have caused a large-scale disaster that killed over hundreds of thousands of people because such an incident occurred.
Deer in the Headlights: Shiro does this when he sees fireballs heading straight at him in Episode 1. Fortunately, Kuroh jumps in to stop them from hitting him. In Episode 9 Seri freezes as well when Mikoto launches a powerful attack at her and the other SCEPTER 4 members who are blocking his way to the entrance.
The King's sanctum is capable of doing this as shown in Episode 1 where Reisi's blue force field protects against the violent surge of fire that Mikoto sends out at SCEPTER 4 when he first activates his powers which burns everything else in its path. The novel K:Side Blue reveals these sanctums are powerful enough to protect the people within them from six simultaneous bomb blasts, a hail of bullets, and other kinds of dangerous psychic attacks.
Saruhiko also throws up a blue barrier with his knives in Episode 9 before Mikoto's attack could reach a group of SCEPTER 4 members, but the attack is so powerful that it simply breaks past it and injures them all anyway.
Elaborate University High: Ashinaka High School, which occupies an entire island off the coast of the city, definitely fits the bill with its impressive size. It has an incredibly vast school ground, beautiful high-rise glass buildings and state of the art technology.
Elemental Hair: Some of the seven Kings seem to have hair colours matching their elements. The fire-using Red King has red hair and the Silver King, ruler of the sky, has silver hair. Averted by the Gold King though, who is shown to have had dark brown hair in the past and has white hair now that he's in his nineties, as well as Ichigen Miwa, the former Colorless King, who had brown hair.
Enigmatic Empowering Entity: The Dresden Slate is a mysterious pulsating rock that is responsible for empowering all of the Kings and being the source of their powers. Not much is known about it or why it does this, however.
Fanservice: As part of its multi-demographic appeal, the series is determined to provide fanservice for all its bases. For the ladies, we've got lots of bishies and Ho Yay. For the gentlemen, there's the Male Gaze with the naked, busty Cat Girl, Seri's ample cleavage, tight clothing, and gratuitously short skirts.
Foreshadowing: K is particularly good at dropping subtle hints that people don't notice until they rewatch. Here are a few examples:
The opening song showed Yashiro falling from the sky. It's significant.
In episode 1, Kukuri says that she keeps an eye on Yashiro because it feels like he would disappear if she didn't. Later she has no idea who he is.
Also in episode 1, the robot reacted by saying, "You're too kind," to a supposedly invisible Neko (Kukuri couldn't see her). Later, it turns out that she isn't actually invisible. She just fiddles with the sensory perceptions of surrounding people such that they cannot see her. It doesn't work on robots, of course.
In episode 2, Shiro looks at a flyer with the name "Marilyn" on it and tells Kuroh that his imaginary sister is named Mari. His own name, "Yashiro Isana", is based on a poster he saw as well, detailing a certain Isana Shrine (Jinja, which consists of the same kanji as "Yashiro"). Additionally, that poster had made appearances in the background prior to this reveal.
In episode 4, the cleaning robot in Yashiro's room doesn't recognize him as a student and tries to clean out the "trash". He's not a student.
Also in episode 4, the alibi photo which Kukuri found of Shiro had Shiro with his coat zipped up. To hide the bloodstains, of course.
Shiro lacks a cellphone, one thing that tells perhaps most about the owner - friends, acquaintances, personal information. Cue False Memories entry.
Shiro is highly competent, such as knowing how to pilot a helicopter, possessing a rational and methodical and almost scientific manner unusual for his age, and knowing exactly how to work flash bombs. Then in Episode 11, it turns out that he is actually Adolf K. Weismann, a German war scientist during World War II...
Fireballs: Izumo uses them in Episode 1 after flicking his cigarette in the air and sending out a bunch of them at Shiro.
First Episode Spoiler: Tatara Totsuka is murdered by a man caught on video and the murderer is believed to be Shiro.
Funny Background Event: In episode 4, when Shiro and Kuroh speak to a member of the school newspaper in the hopes of proving Shiro's alibi, Neko is riding around on one of the cleaning robots, repeating what it says until it actually gets angry. Doubles as a Brick Joke from earlier in the episode, when she got into a fight with another one and wound up jumping on top of its head.
Izumo talks to a man in English. He did a mighty fine job despite the fact that Takahiro Sakurai is a native Japanese.
Izumo(completely in English): This is the guy we are... looking for. See? Look at the gun he has - it's from your place. Don't you know anything about it? (smirk) Relax... and take your time to remember.
The man to whom Izumo is speaking is pretty clearly a native English speaker.
Man(English): Are you little brats from Homura?!
Homura's battle cry.
No Blood, No Bone, No Ash!
Mishina in episode 9.
Gratuitous German: First in the beginning of episode 9, spoken by German researchers. Then at the end of episode 11, when Shiro remembers that he is Adolf K Weismann.
Gray Rain of Depression: When Shiro realizes he is not really who he thinks he is and all his past memories were fake and that he may very well be the murder of Totsuka.
Grey and Gray Morality: Any conflict between Homra and Scepter 4, since neither side is particularly good or evil.
While Kuroh is still trying to kill Yashiro and Neko is pwning him, they stop to eat together. Kuroh cooks. Afterwards he gets up to start killing Yashiro again.
Seri is apparently a regular at Izumo's bar, and the two maintain a rather casual friendship despite their clans being at war.
Hammerspace: Yata pulls his baseball bat twice out of nowhere in the first episode.
Having a Blast: A criminal Strain who appears in the light novel K Side:Blue is described as possessing the power to create an "invisible bomb" from midair which he can then detonate nearby people for explosive results. Naturally, he uses this dangerous psychic weapon with impunity against the riot police officers during a bank robbery attempt, but is eventually stopped when SCEPTER 4 arrives and Reisi proceeds to contain all of his bombs within force fields to prevent them from working.
Hesitation Equals Dishonesty: Yashiro hesitates before giving a fake name for his "little sister", showing the viewer that he's lying. Kuroh does not catch on it, though.
Hufflepuff House: The two unseen/unidentified clans act as this, especially the mysterious Green Clan.
I Lied: Yashiro coming clean about his fake little sister to Kuroh. After he's safely departed the premises, of course.
Idiosyncratic Episode Naming: All the episode titles begin with the letter K, except for the 12th, which features it as a character's middle initial.
Indirect Kiss: In Episode 13 in a flashback with Yata and Fushimi in their middle school days, Yata forcefully grabs Fushimi's drink, drinks from it, and angrily tosses it. Mikoto catches the bottle and proceeds to drink from it as well. So Yata got an indirect kiss from Fushimi, but Mikoto got an indirect kiss from both Yata and Fushimi.
In Medias Res: The first episode begins with an apparent street gang with superpowers breaking into a criminal hideout, beating up the men inside there, interrogating the leader about someone, and then leaving before running into another group with superpowers where they have a brief confrontation. Only near the end of the episode do they start to explain the context of the introduction.
Invocation: The SCEPTER 4 members have to announce their preparation to go into battle by first saying their family names and then "Battou" (literally "drawing the sword") in order to unlock their sabers and draw their powers into the blades.
Jigsaw Puzzle Plot: The series doesn't answer any of the deeper mysteries of the plot right away, and only slowly reveals bits and pieces at a time.
The Law of Conservation of Detail: Relies heavily on this for its storytelling, particularly near the beginning. Some acute fans were quick to notice certain visual clues in the early episodes that hinted at important plot details. Special mention goes to that one inconspicuous poster hanging on the wall of a school building in Episode 4 that foreshadows where Yashiro Isana received his new name and identity. Not to mention the subtle similarities between Adolf Weismann in the past with Yashiro in the present, which lead to the theory that they were the same person well before The Reveal in Episode 11.
Let Them Die Happy: Used humorously with Kuroh when he's out to get Yashiro. The first time he was willing to do Yashiro a last favor for the sake of his ill little sister and the second time he was willing to make Yashiro a nice last meal.
Line-of-Sight Name: In the scene where Kuroh throws Yashiro on the floor while preparing to gut him, a red flyer drifts into the camera. Said red flyer helped Yashiro think of a name for his imaginary sick younger sister. Kuroh liked the name.
Masquerade: Most of the muggles in the setting are completely oblivious to the fact that their country is being run by seven supernaturally empowered "Kings", or that there are many people born with supernatural powers living amongst them. Only the Kings themselves, their clansmen and some of the Strains are fully in the know, with even the regular police force and government kept somewhat in the dark. The Gold Clan particularly enforces this trope by wiping the memories of any normal people who end up getting involved in supernatural affairs.
Medium Blending: The show's preview clips had quite an impact for their art, most notably the different mediums. There's the traditional stop-motion anime style for characters and objects in the foreground, but there are also live-action segments for some backgrounds and certain motion sequences. The styles blend in a strangely appropriate way and are conducive to the somewhat ephemeral and uncanny premise of the show.
Memento MacGuffin: Kuroh's sword is a relic of his deceased king. He obtained it in a test of character after Ichigen Miwa's death.
Memory Wiping Crew: The Gold King's clansmen are capable of erasing memories involving any supernatural affairs or events whenever they arise. By the end of K Side:Red they do this to Anna Kushina's aunt who loses all her memories of ever having a niece as a result.
Episode 4's ending abruptly shifts from the earlier humorous antics of the main trio as they try looking for evidence to prove Shiro's innocence to Shiro discovering the bloodied shirt from the crime scene in his closet and becoming horrified as he remembers the video.
The Fushimi/Yata Drama CD. It's all fun and games for the first ten minutes' interview until the end when it goes into details of their past and showing the reason behind Fushimi's messed up personality.
Moment Of Silence: When Mikoto punches a hole through Shiro's chest, and again when Reisi stabs Mikoto before his Sword of Damocles could drop onto him.
The Movie: The sequel to the first season is announced to be a movie.
Multiple Demographic Appeal: This is what the developers seem to be aiming for. The cast is full of all kinds of bishonen, but also has various types of women with differing fanboy appeal.
Mundane Utility: The power of the Silver King lets his clansmen levitate themselves and fly. While that in itself has quite a few mundane uses, the King temporarily makes people his clansmen so that he can float them and move them around easier.
Mutant Draft Board: According to the novel K Side:Red, there is a research center (disguised as a hospital), under the Gold King's jurisdiction, where Strains are regularly sent for residence and education as well as to hide them from the public eye. By the end of the novel, however, it gets closed down temporarily.
Named Weapons: Kuroh's special sword is known as Kotowari. According to Word of God (via Twitter), each of the SCEPTER 4 members' swords are named as well (e.g. Reisi's sword is named after a star, Seri's sword is named after a flower).
Neck Lift: A variation in Episode 2. Kuroh lifts Yashiro by the back of his uniform's collar while he was preparing to stab him with his sword.
Ode to Joy: Yashiro hums it twice in Episode 1, when walking around the school, carefree. Later, in the video broadcasted through the city, the Yashiro-lookalike in the video also hums the same song. Returns in Episode 4, once again by Yashiro.
Oh Crap: Yashiro in Episode 2 when he sees Kuroh again after barely escaping from him with his life earlier.
Order Versus Chaos: The Blue clan versus the Red. The Blues have uniforms, all wield the same weapon (a sword), ritualistically announce themselves before drawing their swords or using their powers, and are basically a second police force. The Reds are pretty much a street gang with superpowers, to the point that most of their weapons are baseball bats and skateboards.
Our Souls Are Different: The Silver King's soul escaped from his original body and went into another nearby one with all his powers and consciousness intact after the Colorless King tried to possess him. The Colorless King's powers also presumably operate this way by allowing his soul to take over different bodies at will by slipping into them through the eyes. Additionally, according to one of the side novels, the King's soul is actually connected to the Dresden Slate psychically which is where they draw all of their powers from.
Panty Shot: An incredibly egregious one happens at the end of Episode 5 to Kukuri when Yata talks to her. They happen again to Kukuri in the last episodes as well.
Pillar of Light: Episode 11. When Shiro awakens as the Silver King, Adolf K. Weismann, a pillar of light appears where he is, eventually dissolving to reveal his Sword of Damocles.
Shiro:*sad smile* Please go ahead and do whatever you like with me.
Kuroh:*grin* You've finally accepted your fate! *prepares to stab him*
Shiro: Wait wait wait wait!
Portent of Doom: The sword of Damocles is not only a sign of a King's immense power but is also a sign of great danger since it is capable of destroying the surrounding environment and killing off thousands of people if it ever drops due to the King losing control over their powers.
Power at a Price: The seven humans who are chosen to become Kings receive tremendous supernatural powers at the price of having a literal sword of Damocles always hanging above their heads, which can easily kill them (and everyone around them) at any time should their powers grow completely out of control.
Power Levels: The "Weismann levels" are used as a scientific measure of a King's powers, with the numbers quantifying the current level of power being used as well as indicating the stability of the King's power (higher numbers indicate greater instability). Episode 1 shows that SCEPTER 4's technology can allow them to track it accurately when Mikoto uses enough power to release his Sword of Damocles.
Power Source: The source of all the Kings' powers is revealed to be a mysterious object known as the Dresden Slate, which is an ancient-looking tablet with inscriptions on it. How it chooses Kings is unknown, except once it does pick someone, the chosen person (or animal) has a customized Sword of Damocles that literally hangs overhead whenever they activate their powers and is called a Sword Aura.
Powers in the First Episode: The first episode features both the Red and Blue clans and their respective powers as they face off, and later goes on to show Kuroh displaying his own powers to rescue Shiro from a sticky situation.
Prophecies Are Always Right: At first, it seemed like Ichigen's prediction that the next Colorless King must be killed if he's evil is wrong when Shiro is the one believed to be his successor. However, his prophecy is later proven to be true without a doubt when the real Colorless King finally shows himself.
Psychic Powers: The seven Kings are said to have psychic powers that can affect the reality around them. Their clansmen and Strains have these powers as well, only to a weaker degree.
Psychoactive Powers: The Kings must always keep a sense of balance and remain mentally stable at all times in order to maintain constant control over their immense powers. The Sword of Damocles literally enforces this rule on them by dropping if they were to ever lose control over that delicate balance.
Randomly Gifted: The Strains, a name that refers to people or animals spontaneously born with supernatural powers without receiving them from a King, are an example of this since no one knows where their powers come from. However, it is at least theorized in one of the side novels that their powers might have come from the Dresden Slate as well, and that they are possibly people who failed to become Kings despite receiving power from it. The Kings themselves are also an example since they are randomly chosen by the Slate for unknown reasons to command over others.
Reality Warper: According to the side novel, all Kings are practically demigods who can bend, twist and distort the laws of physics that govern the world to their liking.
The Reveal: Shiro is Adolf K. Weissman, having lost his memories because of the Colorless King.
Running Gag: Kuroh using his cassette followed by Yashiro saying "Creepy!"
Rustproof Blood: The bloodied shirt in Yashiro's closet from the night of Tatara Totsuka's murder still has the blood fresh red instead of dried brown.
School Festival: So far, all episodes are set before this event, which is why all the students are so busy preparing.
Screen Shake: In Episode 4, when Yashiro opened his closet to find a blood-stained shirt inside, to show his current mental state. It also shows elements of an Impairment Shot.
Screw the Rules, I Have Supernatural Powers!: The side novels reveal that there are many people naturally born with supernatural powers (known as Strains) who only end up using them for crime or violence, including bank robbery attempts. The level of danger they represent with their powers is ranked according to class: common (weak) and Beta (powerful).
Sentient Phlebotinum: The side novel reveals the Dresden Slate is actually alive and has a pulse that it can link with the humans who are chosen to become Kings. The Slate also imparts a sense of knowledge to the Kings about their purpose after giving them power.
Sequel Hook: Both Kuroh and Neko express hope that Shiro might still be alive and are last shown running off somewhere while hiding themselves in illusory animal forms.
Shoo Out the Clowns: The cleaning robots don't appear in episode 6 which is quite an intense episode.
Shout-Out: In episode 3 when Kusanagi's bar gets hurt, his reflection in the falling glass is in The Scream pose.
Show, Don't Tell: Makes considerable use of this. Exposition is almost entirely nonexistent (except in Episode 3), and the characters' motives are almost never fully disclosed to the audience due to a lack of interior monologue, making their spoken words and actions all the more meaningful as well as the driving forces of their characterization.
Slasher Smile: The "Yashiro" in the video, as he shoots the camera.
Snow Means Death: Teased, seemingly averted, and finally played heartbreakingly straight.
HOMRA's romanization - "HOMRA", "Homura" or "Howling Flame"?
Sphere of Power: Both the Red King and Blue King have one which is shown briefly in Episode 1 when they activate their powers. These are called the King's sanctum and are able to protect the people inside them from harm as well as strengthen the powers of the clansmen serving the King.
Spin-Off: Since a one cour anime could not possibly provide enough details about the universe and its large cast within such a limited frame of time, there are many supplementary materials that help to elaborate on the setting and the characters' backstories, including manga adaptations and novels.
Squeaky Eyes: When Yashiro and Neko blink in disbelief at Kuroh gushing about his master, in Episode 3. Saruhiko does this in Episode 8 when Seri offers him to sit down and eat the gross dessert she's made.
Stock Footage: The opening sequence reuses quite a few scenes that are later shown in the episodes themselves. There's also that egregious Male Gaze focus on Seri whenever she starts swinging her sword at someone which has been reused three times. The eight minor SCEPTER 4 characters who announce their names and then draw their swords in orderly fashion has also been reused three times. Episode 11 is especially guilty of recycling quite a number of scenes during battle, although Episode 12 does as well.
Super Empowering: The Kings are all able to empower ordinary individuals with the same kind of powers they possess, usually after they pass a test to prove their worthiness. For example, in HOMRA, newcomers need to pass a test where they must shake hands (or otherwise come into physical contact) with Mikoto while his hand is on fire. The powers bestowed on the clansmen appear to be permanent once acquired, however, since choosing to leave the clan afterward doesn't remove them as Saruhiko reveals in Episode 5. The death of the King doesn't take away their powers either since the original SCEPTER 4 members were able to keep their powers while working in the organization for ten years after the first Blue King's death.
Super Power Lottery: The seven Kings' powers appear to be ranked according to this: while the Red and Blue Kings only have powers specializing in either offense or defense and are ranked as third and fourth respectively, and the Gold King is able to draw out the latent talents of his clansmen to reach their full potential as the second, the Silver King as the first is said to possess immortality and has not even aged a day after gaining his powers, as well as having control over gravity. Likewise, the previous Colorless King's power was explicitly a less ostentatious ability to sense the future. The current Colorless King can merely possess the bodies of others and is otherwise not even a physical match for Kuroh (who, in turn, is nowhere near as formidable a fighter as the Blue and Red kings).
Super Power Meltdown: If any of the Sword of Damocles (the large floating swords that appear whenever the Kings release a large amount of power) were to ever fall to the ground, they would cause an explosion powerful enough to destroy a large city and leave a massive crater in its place.
Super Registration Act: The side novels reveal that SCEPTER 4 regularly enforces this law, particularly towards Strains. While the organization outwardly claims to be a mere family registry division of the Tokyo Legal Affairs Bureau (fourth annex), they are really only interested in registering and keeping tabs on supernaturally empowered beings. Their register office even alludes indirectly to their real purpose by claiming to be a registry for "special foreigners," which is actually a metaphor for people who possess special powers, not those born from a different nationality. In the past, they also sent any unregistered Strains they discovered to a specific research center meant for residential and educational purposes.
Sword of Damocles: Literal giant swords appear floating in the sky in the first episode when the Red and Blue Kings activate their powers, and are described specifically as the "swords of Damocles." Similar to the legend, they always hang directly overhead when released by a King, and must remain airborne at all times. If any of them should ever fall, they'll create an enormous crater after exploding on impact with the ground. They seem to reflect their Kings' condition by their appearance as well (disintegrating swords are a sign of emotional strain).
Synchronization: K Side:Red reveals that the seven people who become Kings must be able to synchronize their heartbeats to the "pulse" of the Dresden Slate in order to establish a psychic link through their soul and receive great powers.
Taking You with Me: Adolf K. Weissman attempted this in Episode 8 when he screams at the SCEPTER 4 helicopters to get closer and closer to his Zeppelin, and when one of them finally does he immediately presses a button that causes his entire airship to explode. This is revealed to have been the Colorless King's actions and not his own, though.
Tall, Dark and Handsome: Kuroh Yatogami and Reisi Munakata's designs follow the same aesthetic—tall, dark long hair, pretty face and slim bishonen build in long cloaks.
Technicolor Blade: The SCEPTER 4 members are described in the side novel as channeling a form of synchrotron radiation that glows blue in their sabers when they release their powers. The fortification also gives these swords the ability to cut through things quite easily.
Technicolor Fire: The HOMRA clansmen's fire powers are often bright pink or violet-colored rather than red.
That Liar Lies: When Yashiro goes around trying to find a solid alibi, his words are all shot down by other evidence.
Twenty Minutes into the Future: Extremely recent, in fact. According to K Side:Blue (which chronologically takes place at least a year or two before the anime's storyline), the year is 201X.
Unusually Uninteresting Sight: Averted in Episode 1 where Shiro's white hair becomes noticeable enough for a HOMRA member to spot him from a distance and immediately contact the others. Otherwise, it gets played straight by most of the civilians walking around in the city who seem indifferent to the psychic battles that are going on around them.
Most of the superhuman characters have Charles Atlas Superpowers and/or the ability to spew flames everywhere. Neko's abilities, though, seem very out of place. She can use illusions that affect all five senses, and has the ability to implant or manipulate memories in other people. Her powers are both Played for Laughs and serious usage.
This is something that's generally true of Strains - people who develop supernatural powers seemingly naturally, without becoming a King's clansmen. While clansmen generally obtain powers similar to that of their King, all bets are off for Strains.
You Gotta Have Blue Hair: Among the main characters, Yashiro, Anna and Adolf K. Weismann all have white hair while Neko has pink hair. A few minor characters have some odd hair colors as well, such as one SCEPTER 4 member who has blue hair and a female high school student who has dark green hair.
