Tropes associated with the main characters in general:
Club Stub: Ryouta was the only member of the Astronomy Club, since the previous members all graduated. During his first year, there was only him and an upperclassman. Now there are more members in this club.
Cool Shades: With the exception of Kana (and Hatsuna, who wasn't introduced at that time), the others wear sunglasses to protect themselves from Nanami's power.
Locked Out of the Loop: Generally Ryouta and the Magic Users try to keep as many people from finding out about their predicament as possible. Though he tells his uncle about them, it's because he needs the latter's help in making the pills the girls need to stay alive. And in Kikka's case, he asks the girls while they're at the beach in chapter 56 not to let her see them using their powers. Both Kana and Kotori end up accidentally doing so, mainly to prevent another girl from drowning, and Kikka gets teleported into the water with Kotori. When she wakes up later they play it off as her passing out from too much sun.
Mass "Oh, Crap!": In chapter 59/episode 11, Ryouta mentions the name "Valkyria". All of the girls immediately have this look on their face, and explain to him that Valkyria is extremely dangerous, killing people like insects and being able to utilize eight forms of magic. And she shows up in the observatory where the other girls are hiding at in the end of the chapter/episode.
Pretty Freeloaders: Kana, Kuroha, and Kazumi all move into the observatory where Ryouta's Astronomy club meets in episode 4. They're forced to move there after Kuroha accidentally burns down the house she and Kana were staying in. And in Kazumi's case, her hideout was also getting torn down, so transfers to his school and applies for the club to make it less suspicious if she's seen going in and out of it everyday. Kotori also ends up joining them in episode 6 after Ryouta convinces her it's better to move there than to continue living where her friend died. And then Hatsuna joins in.
They Would Cut You Up: Why Ryouta and the escaped magic users don't simply go public? Ryouta claims they would simply end up back on the experiment table. Which is odd considering the lengths the antagonists themselves go to to keep ordinary people finding out about the magic users, but then, if the central conflict could be resolved that easily, there would be no story. He also overhears Kuroha telling Kana that if he did try to befriend her, they'd go after him too. Despite that, Ryouta still takes the risk of trying to befriend her and the other witches he runs into.
Unwanted Harem: In the straightest way possible. Ryouta doesn't want more girls to be in danger, and every new girl just adds too many problems to the mix. Especially since every new addition to the group puts more strain on their stockpiles of the pills that keep the girls alive.
Yank the Dog's Chain: Securing more pills. Particularly when it comes to getting Kogorou to manufacture more. The attempt to reverse manufacture them comes with the clause that it will either be doable within a month or take at least half a year, and it turns out it will take the longer period of time. The second attempt he finds information that lets him pull it off in a month, but by the time he comes across the means to do this, there are only enough pills to last everyone a week.
The protagonist of the series, a brilliant high-school student aiming to become a NASA researcher. Still tormented by the death of his childhood friend, a girl named "Kuroneko", which he blames himself for, he wants to prove the existence of aliens as an atonement to her. This makes Neko Kuroha's sudden appearance all the more disturbing to him.Soon enough, Ryouta finds himself taking care of Kuroha and other Magic Users out of kindness and a desire to never again fail in protecting a friend.
Tropes associated with Ryōta Murakami:
Above the Influence: Because of his still unforgotten childhood crush, Ryouta doesn't try to make any moves on the girls, even after Kazumi's successive teasing and attempting to get into his pants.
Accidental Kiss: Ryouta has one of these in chapter 65. Kazumi was actually going to try and force him into having sex with her, but in the end chickens out from even kissing him. She tries to leave the park, but he says they should stay a little bit since they just got there. She then trips and they accidentally kiss before tumbling down the hill together.
Accidental Pervert: Occasionally. Not helped at all by his difficulties in understanding women.
Ain't Too Proud to Beg: Ryouta grovels before Ichijiku and Valkyria in episode 12. It's a distraction, so Hatsuna can sneak up behind to push on Valkyria's eject button. Unfortunately, Valkyria's Harness looks completely different than the normal ones, and the plan fails.
Awesomeness by Analysis: Ryouta figures out the abilities of most assassin magic users very quickly, and abuses their weaknesses to defeat them.
Badass Boast: "They may have AAA rank witches, but they don't have me." Wow.
Badass Normal: Armed with only his Photographic Memory, Ryouta has proved himself time and again to be as dangerous as the Magicians that he and the girls must fight off on a frequent basis to stay alive to the point that he is the defacto strategist that comes with up with the plans that save the day.
Because You Were Nice to Me: Arguably why the girls are largely attracted to Ryouta. He doesn't treat them differently than other people, and often goes out of his way to help them when he can. The fact that he's also a good looking guy helps out as well, especially with Kuroha and Kazumi.
Blank White Eyes: Ryouta displays some in chapter 55, after placing second place in test scores at school. Kuroha places first, and he begins to recall that Kuroneko did well on tests too. He wonders if Kuroha would also be quite intelligent were it not for her constantly losing her memories due to her witch powers.
Cursed with Awesome: How Ryouta views his Photographic Memory at times. He wishes there were certain things he could forget, such as the death of his friend Kuroneko. However, Kuroha tells him that having not being able to forget is much better than not being able to remember.
Disappeared Dad: His father and his little brother died in an accident when he was two.
Distracted by the Sexy: When he sees Kotori in a bikini. This causes Kuroha to ask him what he's looking after a while.
Dynamic Entry: Ryouta does one in chapter 83, flying in feet first to kick Ichijiku in the head in his attempt to save Kuroha from Valkyria.
Considering this is used in all three of Lynn Okamoto's manga series (including being in the same direction and being a full double page), this may count as a Signature Style.
Enemy Mine: Ryouta is forced to work with Hexenjagd in order to stop Ichijiku's twisted plan in chapter 79/episode 12. They sweeten the deal by promising to give him the formula to create the death suppressant pills he sorely needs for his friends. to awaken "Grane" the life form in Kotori, which is capable of destroying all humans.
Expy: Plotwise, he's a mild expy of Kohta with an extra dose of sanity.
First Kiss: Ryouta has his first lip to lip one in chapter 63, by Hatsuna, a witch they just met recently, and whom he went through a lot of trouble to help save from her "accident" of climbing up a tower and "slipping". He thinks to himself that it wasn't bad, but hated that it was in front of Kuroha, who also wasn't happy to see that.
Genre Savvy: Ryouta makes some very intelligent moves, from only doing online research on the girls and the facility through proxy servers, to earning the trust of a skilled biomedical engineer in the hopes of getting an imitation of the pills.
Half the Man He Used to Be: Ryouta gets this treatment from Saori, but she's forced to revert time back a minute due to him stabbing her in the heart prior to getting killed.
Heroic Sacrifice: Subverted twice in chapters 72 and 73/episode 12. Ryouta pushes Kuroha out of the way of Valkyria's attack, but gets fatally injured in the process. Though his heart stops beating, Hatsuna attempts to heal him, and melts in the process. However, due to her Healing Factor, while she's in a melted state, she is still alive, albeit hung up so she can't heal herself at that point. And Ryouta survives as well.
Indirect Kiss: Two instances are brought up or occur in episode 10:
Ryouta does one with Kazumi when she has him try a sample of her food at the maid cafe in Akihabara in episode 7. She later brings this up in episode 10, claiming to have kissed him. Kuroha doesn't take this too well, and a tree branch somehow breaks off and smashes the table they were using. When Kazumi tells Ryouta more specifics about it, the main trunk then also smashes down near where he was at. Kuroha later runs off and is seen singing that she doesn't care about who kisses who, and that an indirect kiss isn't a real kiss.
Later, Ryouta offers her a bottle of water he had on him after she complains about being thirsty. It then occurs to her after taking a sip that he also drank from it, and realizes she also just indirectly kissed him.
Laser-Guided Amnesia: Ryouta is on the receiving end of this when Nanami tries to erase all of his memories, but it's revealed later that her power doesn't work on him due to his eidetic memory.
Last Name Basis: The girls call him by his last name, and he calls Neko by her last name.
The Leader: Type I, II and IV for the Five-Man Band. If he's not there, the chance of success would decrease to 10%.
Loophole Abuse: Kana says she foresees Kuroha's death when she tries to get more pills in episode 3. After Ryouta makes up his mind to save her, Kana also foresees his death as well. Saori does in fact kill Kuroha in episode 3, then she also kills Ryouta. But because he stabbed her in the heart, she's forced to use her magic to rewind time back a minute, lest she also dies. Fortunately for the heroes, using said spell uses up a lot of her magic, and she's easily caught and tied up after using it. So Kana wasn't wrong, but she also didn't foresee Saori having to turn back time, in essence saving the two in the process.
Love Confession: Ryouta gives one to Kuroha in chapter 95 as he attempts to press one of Kuroha's harnest buttons.
Manly Tears: Ryouta displays some in the opening of the anime. He also does it in chapter 70 when he sees the moles on Kuroha's breast, and confirms without a doubt that she is his childhood friend, even though she doesn't remember her past due to her powers.
Morality Chain: Ryouta has been acting as one for the Magic Users he's saved.
Morton's Fork: Ryouta is presented with one by Kogorou in chapter 68. They can probably make more pills within a month due to some new information he received. Unfortunately they only have 42 pills left, and now there are 5 girls that have to share it. So he can either save one girl, or they would all die within a week if they kept taking pills together.
Not a Date: Kazumi teases Ryouta about this in episode 7 when she goes with him to Akihabara and acts the part of a girlfriend. But he tells her that it's not a date and she's not his girlfriend. Despite that, they do end up doing date-like things, such as going to a maid cafe.
Not Distracted by the Sexy: In episode 9, he suddenly enters the hot spring to warn the girls from an assassin, despite he knows that they are bathing in it. Of course, the girls are scared by this, but he completely ignores them and says "There is no time for this" with totally serious face (it's not even red).
In the manga he says "Shut up! You're [bathing] too slow!" instead.
Only Sane Man: Being in a group with abnormal empowered girls, it's not a surprise.
Photographic Memory: Ryouta might have Hyperthymesia, or at least something similar to the condition, as he never forgets anything. He's able to recall a day's events down to minute details, and has also displayed highly keen observation and deduction skills. For example, one part has him trying to remember writing in German from a building; he remembered the entire thing at 100% accuracy in the span of a few minutes. It also makes him immune to memory wipes.
Reused Character Design: Ryouta is the most obvious example of this series. He's one of the many characters who share the design of Rie from Flip Flap. Ryouta's predecessors are Waiko (after her hair cut) from Lime Yellow, Sera Wyoming from Elfenlied, Kasumi from Digitopolis, Yuka from Elfen Lied, and Nono Nonomiya from Nononono. What makes Ryouta unique is the fact that he's male.
Screw Destiny: Ryouta has this outlook when Kuroha tells him about his future in the first episode. If not for her timely arrival, he would have died.
Secret Keeper: He's forced to do this a couple of times for different situations:
The first is he can't reveal the witches out of fear that Vingulf would then track them down and kill them.
He goes through a second one in chapter 113, when Kana tells him not to reveal to the other girls about the drasil hatching, due to the possibility that they may eject themselves to avoid such a fate, especially Kuroha. Though they were warned by Hexenjagd that this could happen, it took a witch actually hatching for them to believe it. He later tells Kazumi and the others that Kana was merely attacked by other witches and was saved by Hexenjagd.
Single-Target Sexuality: Though he denies it, there's little doubt Ryouta is interested in Kuroha, especially when he strongly suspects it's Kuroneko. Up until she showed up, he didn't even seem interested in women since losing Kuroneko.
The Smart Guy: Other than being brilliant in school, he often manages to quickly elaborate effective plans to take down the Magic User assassins, and understands Nanami's ability in (literally) the blink of an eye.
The Strategist: Ryouta is able to form decent plans fairly quickly based on what he knows about the witches he's up against. Against Saori, he stabs her in the heart to force her to use her time rewind ability to reverse time, which also cripples her due to the immense power needed for that. And against Kikako he at first was going to have Kuroha distract her until he could get behind the former to hit her harnest. But when he sees Kotori tying herself up and planning to switch places with Kuroha, he instead has her switch places with Kikako instead so they could immobilize her. It works spectacularly.
Survivors Guilt: Ryouta is traumatized by the accident he had with Kuroneko years earlier when they fell off a pipe while traversing a dam. As a result, he vows to find the existence of aliens for his friend, and has trouble associating with girls as a result.
Suspiciously Specific Denial: In episode 7, Kuroha steps out of the room briefly at the karaoke bar to use the bathroom, but runs into Ryouta. He claims he's not there to see her, and was just going to sing alone.
Taking the Bullet: Well, it's not a gunshot, but Ryouta does this for Kuroha in chapter 71 when he pushes her out of Valkyria's attack and gets hit by it.
Techno Babble: Ryouta's explanation of RSAnote the de-facto example of real-life asymmetric encryption and the processes within organic chemistrynote the discipline that is used to create and discover real-life compounds and medicines leaves a lot to be desired.
In the first episode of the anime, Kuroha warns Ryouta at first to catch the last bus near the observatory, but then tells him not to catch it and to instead stay where he's at already for the night. He says that the weather should be clear, only to then have it start raining. And he also decides to leave and deliberately miss the last bus, figuring he probably wouldn't be a victim of a crime in such a remote location. He then wonders what could happen locally, then notices a mudslide coming down on him, which also traps him while a giant boulder falls.
In chapter 59, as Ryouta is told about how dangerous Valkyria is, he says that they haven't been found out yet, so they should be safe. Then he's told one of the magics they can use is to track down other witches. One of the walls suddenly explode and Valkyria, who also looks suspiciously like Kuroha, is seen demanding their pills.
In episode 10, after Ryouta checks on Kuroha while she's singing by herself, he tries to leave quietly so she wouldn't notice his presence. Then he accidentally kicks over a nearby can...
Thanks For The Mammaries: Ryouta accidentally does this to Kuroha in episode 4. Due to the distraction, he realizes moments later that he didn't check to see if she has the moles on her chest like her old friend Kuroneko.
Token Human: The girls around him are not human anymore (at least not biologically).
Too Dumb to Live: In the first chapter/episode, but subverted. Ryouta didn't give a damn about losing his life just to get the proof if Neko was saying the truth.
Wham Line: One occurs in episode 7, when the girls ask Ryouta if the guy he took the pill to can recreate the pills for them. He pauses for a moment, and then says they can't. Despite that, Kuroha says they should keep trying for future witches who may escape, and Kazumi goes outside to cry.
What the Hell, Hero?: His reaction to Neko and Kotori being hanged up after they wasted their magic for unnecessary things in the same day when Kogorou wants to see their magic abilities. Since the magic of these two girls looks more believable than Kazumi's whose magic looks just like hacking and Kana being not able to control visions, Neko and Kotori really screw up and almost causes the loss of Kogorou's support and trust on Ryouta. Thanks to Kana's vision, the girls get a new chance.
The Deuteragonist, this girl is the spitting image of Kuroneko, Ryota's childhood friend whom he was in love with. She registered to his prestigious high-school despite being barely able to read and claiming to have never met him, just so she could save him from an accidental death. Her psychic powers allow her to destroy any object within her field of vision, but it doesn't work on living beings. In the very end of the first manga volume and episode 3, it's revealed that she is in fact Kuroneko.
Tropes associated with Neko Kuroha:
Action Girl: The only female character who has fighting abilities. And she's the ones who fights the villain magicians.
Badass: Neko's ability allows her to destroy everything, but she's not really good in fighting, which makes her not that badass. However, Kuroneko on the other hand is much more powerful and reaches DBZ levels.
Berserk Button: Don't mess with her poor memory or that she does not know things. Or threatening her friends or flirting with Ryouta.
At the very beginning of the series, Neko saves Ryouta from being crushed by giant rock.
Ryouta is rescued from an arrest in episode 8 when Kuroha and Kotori show up to save him, using the info that Kazumi obtained from him as far as where he was going that day.
Book Dumb: Played straight at first. Kuroha is unable to do simple multiplication despite being in the same class as Ryouta. He is understandably baffled at how she's even in that school if she can't do math. She also can't read very well either, and he tells her that her cover is going to get blown if she's trying to blend in this way. However, she's later seen doing a complex math problem in class, and Ryouta mentions how amazingly fast she picked up on high school subjects. Kana mentions later that Kuroha loses some of her memories when she uses her spells.
Blank Slate: What essentially happens when she's finished with her real personality. Due to the weird way it works, every time she uses her main powers (i.e., her third button), after she hangs up, she gets reset to the point when she doesn't remember anything except some basic things. Saving the experiences, however, is nonexistant.
Cassandra Truth: Kuroha tells Ryouta various things, such as not to miss the last bus, but then later tells him to stay at the observatory. Naturally he doesn't exactly believe her, and wonders what could possibly happen in the rain out in a remote road near a mountain. Then a mudslide occurs...
Cast from Hit Points: Kana explains to Ryouta that Kuroha loses some of her memories anytime she has to use her powers. Which goes with what she said in the previous episode when Ryouta complained about not being able to forget certain things, and she tells him it's better than not being able to remember them. It is also implied that if not for this problem Neko would be ranked at a higher level of power and destruction.
Clingy Jealous Girl: After developing feelings for Ryouta, she often subconsciously destroys things with her power without meaning to.
In episode 5 she causes a table to randomly explode after Kazumi gets a little too close to Ryouta for her liking.
In episode 10, a branch from a nearby tree falls down near them after Kazumi mentions having shared an Indirect Kiss with him while they were in Akihabara. The rest of the tree breaks after Kazumi shares more info on that incident.
In chapter 107, despite having lost much of her memories again, and acting rather cold towards Ryouta for the most part, she retains this jealousy. After Kazumi insists he try the "ice cream special", Kuroha slams a glass of water on his table. Interestingly she manages to prevent anything strange from happening, though it's clear she's not happy seeing both Kazumi and Hatsuna trying to one-up each other with him in the cafe.
Clothing Damage: Kuroha suffers some during her fight with Saori. Aside from the obvious Fanservice, this also allows Ryouta to see the three moles his friend Kuroneko had, and he then realizes she was still alive. At least until Saori turns her into a bloody mess. Saori later reverts time to before she killed Kuroha, and subsequently before Ryouta saw it, so he's still unaware of it until he sees them later again.
Deuteragonist: The main female heroine and the second protagonist.
Distinguishing Mark: She has Kuroneko's three moles near her left armpit. Ryōta only fails to notice them because of her body growing up and the moles changing places. He does notice them at some point, but forgets about it soon after because Saori rewinded time to before it happened.
Doesnt Know Her Own Strength: When Ryouta challenges Kuroha to an arm wrestling contest, she easily defeats him. However, she slams his hand rather hand onto the table, as he's wincing in pain afterwards. He then gropes her arm and wonders how she managed to do that.
The Dreaded: Valkyria seems to be quite afraid of Kuroha when they first meet, and she ends up not attacking everyone in the observatory as a result. Kuroha later confirms that she's even more powerful than the former, though it takes quite a bit to stop her, and she loses her memories again after their long fight.
Everyone Can See It: After Kuroha accidentally shoots down a boy, her friend tells her that the reason she feels uneasy when Ryouta touches her hand is because she likes him. The camera then pans along several of the other guys and girls present, showing the rejected guy looking down, and the others snickering at how innocent she is.
Expy: To Lucy, although mostly from a storytelling perspective as opposed to personality. Neko has a power that spontaneously destroys objects, similar to how Lucy's power involves spontaneous dismemberment (among other things) of the human body. Both are feared in-universe for being extraordinary powerful members of their respective species. Both have to deal with Laser-Guided Amnesia due to combat-related scenarios (a bullet for Lucy, and a superpower disability for Neko). Both are childhood friends of the male lead (Kouta for Lucy and Ryouta for Neko), who have to deal with the other part of the pair being unable to remember them for a good while (although it's reversed in this case, ala Kouta for Lucy and Neko for Ryouta). Both have Clingy Jealous Girl issues regarding the man they love (although it's so much less violent for Neko than it is for Lucy). The biggest difference (other than Lucy being the main character as opposed to the Deuteragonist like Neko), is that Neko is normally a very pleasant person from the get-go, despite some aforementioned Clingy Jealous Girl problems, whereas Lucy was a straight-up Byronic Hero. The closest Neko and Lucy have ever been in personality is when Neko develops a cold shoulder towards Ryouta upon forgetting her memories as Kuroha as well as Kuroneko, and even then, that's incredibly minor compared to Lucy's epic Sugar and Ice Personality. On the other hand, her appearance is very similar to Kumiko's sans ponytail, The Heroine of Okamoto's one-shot Allumage.
First Name Basis: To all other Magic Users. Kuroneko calls Ryouta by his first name in contrast to Neko.
Go Through Me: Kuroha does this for Kana in a Flash Back during chapter 94, when some guards seemed to want to kill the latter. This is why Kana does what she can to help her out, such as with her foresight powers.
He Is Not My Boyfriend: Kuroha tries to state this regarding Ryouta to Kana, Kazumi, and Kotori. She says he's only interested in helping her because she looks like his childhood friend that died. But later chapters in the manga show she is interested in him, and doesn't like seeing other girls make moves on him, whether it's just flirting or even kissing him.
Heroic Second Wind: Kuroha gets one in chapter 95 after Ryouta presses the top button on her harnest. It works, and she regains her memories as Kuroneko as well, as she has no idea who Kuroha is.
Love Epiphany: In episode 4, Kuroha says she feels hot and uneasy after Ryouta accidentally gropes her in the bath. She thinks she may have caught a cold. By episode 7, Kana pretty much points this out to her. Kuroha even wonders why she feels uneasy when touching Ryouta's hand, but doesn't feel anything when she touches a random boy's hand at the karaoke joint.
Love Hurts: Kuroha isn't happy to see other girls hitting on Ryouta, such as Kazumi. In later chapters of the manga she often goes outside and tries to sing that whatever she saw happen with him doesn't bother her, though it's pretty obvious she's not happy about it. And in chapter 67 she runs back to her old hiding place in the abandoned village after seeing Kazumi kiss Ryouta. She also wonders why seeing Kazumi around Ryouta makes her heart ache despite forgetting who he was a couple of times.
Major Injury Underreaction: In the beginning of episode 3, Kuroha shows up to school in a lot of bandages. When Ryouta inquires what happened, she simply claims she had a cold. Kuroha later explains they have to take a death suppressant pill every 30 hours or they'll start bleeding, and after 35 hours their internal organs melt and they die. She was attempting to wait until the last minute to take them, but as Ryouta finds out after the opening credits, she took too long this time and was on the floor bleeding.
Malaproper: Because she's so unfamiliar with a normal life she tends to mishear words or casually use terms she doesn't understand.
Never Found the Body: While Ryouta was told Kuroneko was killed in the accident at the dam, he never got to see her body for himself. Hence why when Kuroha shows up and bears a striking resemblance to her, he can't help but think that it's his old friend, despite her claiming she's not Kuroneko. When Kuroha suffers some Clothing Damage in episode 3, he is able to see the three moles near her chest, and realizes Kuroha is Kuroneko. But this part is undone thanks to Saori turning time back a minute, to before he was able to verify it.
Nice Job Breaking It, Hero: Kuroha attempts to boil some water in episode 3, but causes the house to catch on fire instead. Worse, the death suppressant pills they were supposed to take every 30 hours also burned up, and Kana's last dose was yesterday. She starts bleeding from her mouth, but tells Kuroha not to worry about it.
Nice Girl: She's a cheerful, compassionate, and loyal young lady. Despite some shortcomings, she's still a good person at heart.
Nose Bleed: Kuroha suffers one at the end of episode 2. Episode 3 reveals they have to take death suppressant pills every 30 hours, or they'll start bleeding, and after 35 hours, their internal organs melt and they'll die.
Not so Above It All: Ryouta catches Kuroha singing to herself in episode 2 when he tries to find out her address to give her some paperwork from school.
Oblivious to Love: Ryouta is actually interested in Kuroha, though to the other girls he seems to act this way. Hatsuna starts pressing on this issue quite a bit when she shows up in the later chapters of the manga. However, for several of the girls it's an important subject to them because their lack of pills means they may only have days to live at best, if they aren't killed outright by the organization they escaped from first.
Perpetual Poverty: Kuroha and Kana are hiding in an abandoned village, and have no money to buy food or other basic necessities. So when Ryouta shows up with some food and cake, both girls are ecstatic about it.
Pre-Asskicking One-Liner: Delivered by, of all people Kuroneko after she regains her memories while fighting off against her sister Mako, also known as Valkyria.
Valkyria: "Go ahead, attack me if it pleases you. But if you continue to attack me and cause yourself to hang up, I'm going to seize that chance and kill you no matter how much you cry or apologize." Kuroneko: (reawakened as Kuroha) "Onee-chan, it'll be boring if I don't fight against you with a handicap like that."
Screw Destiny: Kuroha also tries to prevent people from dying if she can do anything about it. While some of her interventions require some rather brute force, such as saving Ryouta from a giant boulder, others are a little more vague as to how to resolve it, such as the woman in red that they bump into on the way to save a woman in red from getting hit by a car in episode 2. At first they thought they were too late when they saw the crashed car, but Ryouta realizes that minor incident earlier delayed the lady enough that she wasn't in the path of the car as Kana had foresaw, thus indirectly saving her life.
Single-Target Sexuality: Both her and Kazumi are interested in Ryouta, and he's generally the only guy they will talk to for an extended period of time, much to the chagrin of his male classmates.
Smarter Than You Look: She may seem totally clueless at times, but Ryōta notes that it's just because she never studied, certainly not because she is stupid. And lo and behold, after a few months at school she goes from being unable to read kanji to top of the class!
Suspiciously Specific Denial: In a Flash Back at the beginning of episode 2, Ryouta asks Kuroneko if she's looking forward to going to the beach on a field trip. She says she isn't, but he immediately calls her out on wearing an inflatable tube while stargazing.
Sweet Tooth: To the point that she cries when Ryouta tells her that the cake she is going to keep is actually for him (he gives it to her because of this).
Taking the Bullet: Takes a knife to the chest that was meant for Ryouta, which was shot by Valkyria, echoing the beginning of the arc when Ryouta takes Valkyria's attack for her.
Teleportation Spam: Kuroneko uses her instant teleportation a lot during the battle with Valkyria.
Thousand-Yard Stare: Kuroha does one in episode 5 as she helplessly watches Shino, one of the witches that escaped with her, get partially vaporized by Kikako.
Undead Tax Exemption: Kuroha can only attend school because she knows a very skillful hacker (Kazumi). On top of that, nobody there seems to bat an eye that her outfit isn't the girl's standard school uniform.
Unskilled, but Strong: She is able to destroy everything, but humans (and Magic Users). However, Neko is not good at using her magic in combat and she's just terrible. Averted with Kuroneko, who is not only much stronger, but also skilled.
What Is This Thing You Call Love?: Kuroha clearly has feelings for Ryouta, but does not understand what they are. She even questions why her heart isn't beating fast like it does when she touched Ryouta's hand when her hand was held by another guy in episode 7. She also seems a little uneasy when other girls get a little too close to him such as Kazumi.
Yank the Dog's Chain: Neko's personality return to Kuroneko not only doesn't last, it actually erases all the previous memories she made as her other self, too!
A girl whom Neko escaped with during their transfer from the lab. She ended up completely paralyzed by all the experiments on her, but in exchange gained the power to foresee people's deaths so that they can be prevented. Since only her left hand can move, she uses it to communicate with a small vocal machine. And she has quite a gift of the gab.
Tropes associated with Kana Tachibana:
A-Cup Angst: When Kana is protesting that Ryouta, while he carries her out of a burning building, is just using the opportunity to grope her, he says that she doesn't have anything up there anyway. She doesn't like that remark. Fortunately, she has growth spurt and has now bigger breasts.
An Arm and a Leg: Well, she doesn't get dismembered, but her legs get badly broken fighting the drasil in the hospital. Despite the intense pain, she manages to stay awake long enough to delay the drasil until some help arrives to kill it. She passes out from the pain after the drasil is killed, but fortunately Hatsuna is able to heal her legs.
It is suggested that she can move, but doesn't as it will for some reason upset Neko. She does move, at the cost of losing her foresight.
Big Damn Heroes: When Neko and Ryouta are cornered by Valkyria, Kana sneaks up behind her and stabs her with a knife.
The Big Girl: Since the second part, thanks to her reability to move. Kana trains herself in fighting, using knives and hammers and probably other weapons to protect the others.
Blood from the Mouth: Kana starts to do this after Kuroha explains to Ryouta about their "death suppressant" pills. She mentions that if they don't take the pills every 30 hours or so, they'll start to bleed. And after 35 hours, their internal organs start to melt and they die.
Brought Down to Normal: After her Power Limiter is removed, she is able to move around again. Unfortunately she is also unable to foresee future events any long as well, and her body is rather fragile due to not having used her muscles in a long time. Now she's the second member of the group with fighting abilities.
Brutal Honesty: When she has to say something, she doesn't chew her words.
Cassandra Truth: In chapter 109, when she tells Kitsuka that she's a witch, the latter doesn't believe her, and demands some kind of proof. Unfortunately Kana can't use her abilities while moving around, so can't do anything. Fortunately Rurumi, a witch who was following her with two other girls, provides the proof Kitsuka wanted, and tosses her into the air with her Voodoo Doll in a fit of jealousy at the seemingly normal life Kana seems to be having.
The Chick: Along with Kotori in the first part of the series, due to her disability and being only able to support them with her precognition powers. Becomes The Big Girl in the second part.
Cluster F-Bomb: Often and repeatedly, in a way that contrasts with her appearance.
Cursed with Awesome: Kana has some very useful foresight, but suffers from near-full body paralysis. She gives up her power in order to save Neko and Murakami from Valkyria.
Deadpan Snarker: ...And deadpan everything, as she can barely move her facial muscles.
Double Standard: Abuse, Female on Male: In chapter 106, after he gives a heartwarming speech to Kana, he then mentions not having to take her to the bathroom anymore. She immediately tries to stab him, and then chases after him, attempting to hurt him to make him forget about those incidents.
Expy: With Kana's fringe and her disability, she's an Expy to Mariko to an extend. The authors seems to be aware of it, considering how he designed Kana's character card.
Gainaxing: In chapter 108, when she and Kitsuka do exercise before going swimming, Kana's not so big breasts jiggles, causing an A-Cup Angst reaction to Kitsuka.
Handicapped Badass: Although Kana is paralyzed and can only move her left hand slightly and swallow food, she still has the ability to foresee future events, which helps Kuroha out quite a bit when saving people. Kazumi hints that Kana may in fact be able to move around, but just chooses not to. Kana warns her against revealing too much about her to Kuroha and Ryouta. Her powers also play a key role in fighting against another Seer, giving the heroes the chance to escape unscathed.
Heroic BSOD: Suffers one in chapter 114 after the incident at the hospital involving an awakened Drasil, along with several magicians getting killed there. Made much worse by the fact that Kikka, a Muggle, witnessed all of that happening.
Hidden Buxom: Downplayed hard, since she hasn't big breasts to begin with. Kana looks flatter than Kazumi, but she has actually B-cups, which are bigger than Kazumi's A-cups. Not so hidden anymore since her growth spurt and having bigger breasts now.
I Got Bigger: Since she regained her ability to move she has become taller. Now in the second part of the series, she is not only taller, but has bigger breasts.
Instant Expert: In chapter 108, she's able to start swimming almost right away despite having no previous experience in it. Kitsuka, whom Ryouta had asked to look out for her at school, was supposed to help her, but she can't swim herself, so Kana ends up helping her.
I Owe You My Life: Kana towards Kuroha. The latter saved the former from getting killed off by some guards while both were still in the laboratory, and also helped her escape. She tries to help her friend by warning her of potentially bad events that could occur. Chapter 105 reveals more background on how said event occurred, and Kuroha wanted to help her because of how Kana was unable to do anything by herself.
Knife Nut: Since she regained her ability to move in exchange for her precognition powers, Kana uses knives as her main weapon. Of course, having no special abilities beyond her now lost precog abilities, a knife is her only effective form of attack.
Long-Lost Relative: To her older sister, who shows up since the beginning of the second part and is a reporter who tries to reveal the truth about Vingulf.
Luminescent Blush: Kana displays one after Ryouta says he doesn't mind carrying her around in episode 5.
Power Limiter/Throwing Off the Disability: By pressing the top button of her harnest, Kana loses her foresight abilities in exchange for being able to walk again. Her first act after doing so is stabbing Valkyria in the neck to save Kuroha and Ryouta.
Perpetual Poverty: Kuroha and Kana are hiding in an abandoned village, and have no money to buy food or other basic necessities. So when Ryouta shows up with some food and cake, both girls are ecstatic about it.
Seers: She has the ability to see visions of people who will die in her environment.
Sweet Tooth: She loves sweets so much that she drools when Kitsuka invites her to eat some crepe.
Traumatic Superpower Awakening: She has a moment like this in chapter 112, after being Brought Down to Normal for a while. She has a long vision of Kikka being killed and then Ryouta and Hexenjagd showing up moments after she is eaten. She utilizes this to try and buy some time by delaying the drasil from eating Kikka. Fortunately Misaki arrives in time thanks to the delay to knock Kikka out of the drasil's mouth.
Tsundere: Kana appears as one, even though she's crippled and can only talk with the help of a computer and her left hand.
Unprovoked Pervert Payback: Kana insists that Ryouta wants to molest her every single time he's around; she even does this when he carries her out of a burning house. She gets over this in Chapter 46.
Walking Spoiler: Kana's reability to walk makes her a literally walking spoiler for the second part of the series.
Kana worries she's even more of a burden to the group in chapter 106 after losing her powers. Ryouta says she shouldn't look at it that way, because she was completely dependent on everyone while she was using her powers, to the point that she couldn't even feed herself. She does cheer up a little bit, until he mentions having helped her to the bathroom at times, which causes her to attack him in an attempt to make him forget through pain. He hilariously claims he's forgotten, but she doesn't believe him.
She suffers a Heroic BSOD in chapter 114 due to the incident at the hospital with the drasil and Kikka. Despite that, Kikka tells Kana that she doesn't believe Kana would do the same things that the drasil did if she suffered the same fate, because Kikka believes she's a good person at heart, unlike the witch that awakened.
Half-Japanese, Half-Austrian, this Magic User is a human supercomputer who has the ability to break any informatic code and hack any system through the net. She also happens to be very… forward towards Ryōta as soon as she meets him.
Tropes associated with Kazumi Schlierenzauer:
A-Cup Angst: Ryōta knows it, and doesn't fail to bring it up at every occasion, despite her violent retaliation every time he does. It becomes a Running Gag with time.
Ryouta: "Your breasts aren't really that worth—" (kicked in the face!) "OW!" Kazumi: (Death Glare) "That's no way to talk to a girl when you've seen her secret garden."
Aren't You Going to Ravish Me?: Kazumi strips down naked while visiting Ryouta's house. She practically throws herself on him, but he just barely resists her advances. He instead just tries to go to bed, but is obviously having trouble sleeping knowing there's a girl right next to him.
Armor-Piercing Question: In chapter 55, Kazumi asks Kuroha one, if she likes Ryouta. The former tells the latter that she knows she likes him after everything he's done for them up to this point.
The Bet: Kazumi makes one with Ryouta in episode 10. She says that if she places second (because she's Genre Savvy enough to realize he'd place first), he'd give her something. When he asks, she tells him she wants "his virginity". When he protests, she says he's just going to throw it away anyway. Unfortunately for her, and shockingly for Ryouta, Kuroha places first, while he places second. Kazumi places third, so she technically loses the bet. Kuroha innocently asks him for "a virginity" as well, not knowing what Kazumi really meant by that word.
But Not Too Foreign: Kazumi claims she's half-Austrian and can speak some of it, at least enough to fool Ryouta's classmates into thinking she's transferring in from a school in Austria. This turns out useful when some German writing has to be read.
Ends up becoming one after Hatsuna shows up and shows herself to be even more direct in her love for Ryouta than Kazumi.
In chapter 107 while working at a maid cafe, she does another Indirect Kiss with him via feeding him ice cream. Hatsuna gets rather intimate with Ryouta, having him eat a cherry she had in her mouth. Both she and Kuroha are not happy to see that.
Cry Cute: Kazumi does this after Ryouta tells them the lab he took the pill to can't synthesize it for at least half a year, and they only have about a month's worth of pills left.
Does Not Like Shoes: A tankobon cover had her feet up to the viewer's position, and she already had a lustful personality in the manga proper, so the anime ended up taking this Up to Eleven a la Flanderization whenever they got the chance.
Double Standard: Abuse, Female on Male: Kazumi teases Ryouta in the bath in episode 4, then hits him a couple of times after he insults her chest size. She hits him again in episode 5 after he makes fun of her breast size again. And then she hits him over the head with her bookbag in episode 7 simply because his head looked "whackable".
Erotic Eating: Kazumi and Hatsuna do this in chapter 107 while working at a maid cafe along with Kuroha. Ryouta and Kana pay them a visit while they're working, and Kazumi insists he try "the ice cream special". She feeds him, then takes a spoonful herself, leading to another Indirect Kiss. Hatsuna, not to be outdone, takes the cherry, puts it in her mouth, and feeds it to him via a kiss, and tells him to return the cherry pit to her the same way she fed him with it. Kuroha, for her part, while not happy at seeing said incidents, manages not to make things randomly explode like in earlier incidents. The older man eating there with his wife asks for the ice cream special as well, prompting his wife to scold him.
First Kiss: Kazumi shares hers with Ryouta in chapter 66 after the Accidental Kiss from earlier. She says that she intended this one to be her real first one, and would never forget it even if he tries to. Unfortunately Kuroha also sees this kiss.
Freudian Excuse: Kazumi's constant advances on Ryouta is due to the fact that she could die at any moment. And even if she's not in immediate danger, there's also the risk of running out of pills, which means she wouldn't have long to live anyway. Hence she badly wants a baby with him, so that if she dies, at least she'll have something to prove she existed. Of course he doesn't see it that way, and instead just wants to help them try to live as normal a life as possible. That, and he's interested in Kuroha.
Hopeless Suitor: Kazumi seems to realize she's falling into this around episode 7. Nevertheless, she still likes to tease Ryouta quite a bit. In later chapters of the manga, she tells Kuroha that she likes him, and that if Kuroha doesn't make her moves on him, she would. Then in chapter 68, she asks him who he likes, and he mentions Kuroneko, but thinks Kuroha isn't her due to the lack of moles on her chest. Kazumi later strips Kuroha's top off and spots the moles, confirming that Kuroha is Ryouta's childhood friend and the girl he likes.
Hypocritical Humor: In episode 7, Kazumi asks Ryouta if a shop she points out is where virgins go buy eroge at. She says it loud enough that those guys near the shop can hear her, causing him to tell her to tone her voice down. She then insults him as a virgin, and he immediately fires back that she's one too. She blushes and says that a girl's virginity is worth more.
I Am Not Left-Handed: Kazumi's abilities are actually at an AAA-ranked level, but she failed the test on purpose because she refused to kill a person but didn't say that outright. She feigned a lack of power to do the job.
The Internet Is for Porn: When Kazumi comes over to Ryouta's house to offer him help in finding the location they saw on the device, she says there's nothing he can't hide from her, including his where he lives. She then jokingly suggests looking at his computer to see what porn sites he visits.
Loophole Abuse: Kazumi utilizes this to lower suspicions of her being yet another transfer student, after Ryouta warns her that too many new students coming in, especially to the same class, would look highly unusual. So she makes up a backstory that she transferred in from a school in Austria.
Jerkass: At first she was willing to help Neko and Kana, but only in exchange for anti-death pills. Even after she stops doing that, she still has her jerk moments, like calling Kotori a "fat pig".
Jerk with a Heart of Gold: What Kazumi comes off as to Ryouta. She was pretty demanding that she receives some death suppressant pills from Kuroha in exchange for her help, but after Kuroha explains she doesn't have any, but is going to get more, Kazumi demands half of what they obtain. It's later revealed she was down to one pill herself, and ended up sharing half of it with Kana to prevent the latter from dying.
Ms. Fanservice: Speficially, she seems at least partially designed to appeal to foot- and leg fetishists, given how often shots seem to focus on that part of her body, the manga's cover is particularly unsubtle about it.
In later manga chapters, it's revealed that it's actually Kazumi who's a foot fetishist after Murakami mentions that she isn't wearing shoes, and she asks him if he wants a footjob.
Off with His Head!: By Valkyria who moments earlier just exploded Hatsuna into Ludicrous Gibs. She gets better later however, thanks to Hatsuna being able to heal herself despite the extensive damage, and she also manages to heal Kazumi's decapitation.
Otaku: She's very interested with stuff from Akihabara, including eroges or maid cafes.
Screw the Rules, I'm Doing What's Right: When testing her abilities, the Institute ordered Kazumi to kill a man with her magic. While she had the magical capabilities, because she refused to do it and just "claimed" she didn't have the power, she was relegated to Rank B.
Shameless Fanservice Girl: Has no qualms about being naked around Ryouta in episode 4 while taking a bath. She also holds him rather intimately in episode 5, and even licks his cheek, though she stops once the table behind her and Ryouta suddenly smashes in half uncontrollably by Kuroha. And in episode 7, when he asks why she's stripped down, she tells him it's hot inside the observatory, and teases him some more about it. Then in episode 8 after finding his house, she sits on his bed, and pulls her panties down and asks him to have sex with her.
The Smart Girl: Of the Five-Man Band, though Ryouta is smarter than her. Kazumi's technopathy allows her to manipulate computer systems by using prime factorization, using her brain as her "utility".
Someone to Remember Him By: More like Someone To Remember Me By. Kazumi eventually decides that she wants to make a child with Ryouta as to leave living proof of her existence.
Squee: Kazumi essentially does this the entire time she's in Akihabara with Ryouta in episode 7. She later tells him when they go to a maid cafe that this may be the most fun she's ever had in her life.
Stepford Smiler: Smiles a lot and puts up a cheerful attitude to hide her fears and insecurities.
The Tease: Kazumi does this to Ryouta in episode 4, especially while in hot springs. And again in episode 5, even going so far as to lick him on his cheek.
Tsundere: She may regularly hit Ryōta and call him names, but she also makes no secret that she wants to have sex with him. And can be very direct about it.
Undead Tax Exemption: Kazumi, the girl that helped Kuroha get into Ryouta's school, ends up transferring in as well. When he points out that it would look too suspicious to have that many transfer students in a short amount of time, especially in the same class, she simply tells him that she made her background appear as though she transferred in from a school in Austria. On top of that, it would look less suspicious if she's in the Astronomy club and seen at the observatory later.
Unexplained Recovery: In episode 13. The last time we see her, she's bleeding out. Then she's okay again when the epilogue scenes roll. It's better explained in the manga, and the viewer can guess it in the manga, since Hatsuna is also there.
Wham Line: Played for Laughs when it comes to Kazumi teasing Ryouta, such as sharing an Indirect Kiss at a maid cafe in Akihabara. Bonus points if Kuroha is around to witness or hear about said events. Then random things explode, which she claims had nothing to do with her, despite it being one of her abilities.
What the Hell, Hero?: When Kana starts to question Kazumi about what she knows regarding Valkyria in episode 8 while the two are alone, the latter tries to change the subject on it. Kana however continues to angrily question her on it, causing Kazumi to take her voice modulator away, and starts to strip her clothing off. Kuroha and the others then arrive back home, causing her to question what Kazumi was doing. Kana claims she was being molested, while Kazumi says they were just playing and offers some pudding to Kana. Kotori objects to it because it's her pudding, causing Kazumi to tell her she's getting fat by eating all those sweets.
A shy and kind first year who joins the astronomy club the same day as Kazumi. One of the escaped Magic Users, she is first thought by the group (and narratively implied) to be an assassin sent by the lab, before showing that she truly cares for her new friends. She has the power to switch places with another person by teleportation.
Tropes associated with Kotori Takatori:
Alliterative Name: Kotori Takatori. The kanji of "bird" ("tori") is twice in her full name. It's also a bit of a Punny Name, as Takatori Kotori basically means "tall bird, small bird".
Almost Dead Guy: Already pretty blatant in the manga, but taken Up to Eleven in the anime near the end of the Valkyria arc. In the manga Ryota has to eject Kotori himself to stop Grane's hatching, after which Kotori talks for several minutes before completely melting. In the anime, Ryota arrives almost an hour after she ejected herself, yet she can still talk to him.
Berserk Button: Kotori seems to lose it in chapter 86 after Ichijiku threatens to kill Ryouta, and Valkyria claims to have killed several other witches, specifically by blowing Hatsuna to Ludicrous Gibs, and beheading Kazumi.
She saves Neko from being killed by Kikako when Kotori switches places with the latter.
Ryouta is rescued from an arrest in episode 8 when Kuroha and Kotori show up to save him, using the info that Kazumi obtained from him as far as where he was going that day.
Later she saves Ryouta from his death fall by switching places with him and resetting the kinetic energy.
She later protects Ryouta and Neko from Valkyria and Ichijiku after awakening Grane's power.
Even after her death, her melted body protects Ryouta and Neko from Valkyria's magic by nullifying it partially.
The Chick: Along with Kana, due to her pure supportive magic power.
Cute Clumsy Girl: She drops some juice she was carrying on Kuroha in episode 11/chapter 69. This is also how Ryouta finds out about the three moles Kuroneko had, and he finds out his childhood friend was still alive, albeit without her memories of the past.
D-Cup Distress: Kazumi's polar opposite in that department, which naturally makes the latter jealous.
Death Seeker: Kotori was planning on killing herself, and hopefully doing something heroic beforehand, largely due to Survivors Guilt when her friend stopped taking her pills so she could live long enough to see her birthday in a week. Fortunately Ryouta and Kuroha manage to talk her out of it.
Expy: Hello, Nozomi! Her appearance also strongly resembles Nyu's. The fact that Kotori is a MacGuffin Girl for the plot, gets temporary control of her extremely powerful superpower, and gets a Mercy Kill by the male lead makes her even more of an Nyu expy.
Freudian Excuse: When Kana has a vision of seeing a bloody Kotori smiling over Kuroha, they are understandably on guard as to who she really was. However, Kotori explains why she smiles a lot: Her friend Chie that she escaped with was going to die due to a lack of pills, and didn't want Kotori to be sad anymore, so she asked the latter to always try to smile even when it was sad, so it could help minimize the emotional pain. Ryouta comments later that it caused a lot of problems with Kana's prediction.
Heart Is an Awesome Power: Despite the glaring weaknesses of her magic, Kotori's ability to switch with others has come in handy more often than once. In fact, Kotori's ability has been almost essential to saving a bunch of people, both members and regular civilians.
Heroic Sacrifice: She persuades Ryouta to eject her in order to keep her Grane from killing everyone.
Innocent Fanservice Girl: Along with Neko, who often strip down in their underwear due to it being really hot in the observatory.
Lethal Harmless Powers: Ryouta openly asks how someone with the ability to change places with anything could kill someone. Kana responds by stating how she could jump off a cliff and switch places with her target so they plummet to the ground. Then Ryouta comments that just pushing the enemy is more simple.
MacGuffin Girl: She contains Grane within her body, that's why the organization wants her and Hexenjagd wants to kill her very badly.
Mercy Kill: Murakami is forced to eject Kotori to prevent her harnessed from hatching and wiping out all lifeforms.
Mundane Utility: At one point she uses her ability so she wouldn't be late to school. Note she can only use this once per day and is supposed to be in hiding. Ryouta immediately calls her out on doing such a thing so carelessly.
New Transfer Student: Like Neko and Kazumi, but not in the same class, since she's a first year student. Chie helped her to transfer to that school.
Not the Fall That Kills You: Her ability apparently resets kinetic energy, which means that if she switches places with someone who is at the end of a 10-story fall, the target will land safely instead of ending up as cranberry jam.
Person of Mass Destruction: The normally ditzy Kotori seems to be of special interest due to something inside of her that others claim is capable of killing all humans on the planet.
Power Nullifier: When Grane is awakening it has an even greater nullifying effect and it's permanent.
"The Reason You Suck" Speech: Having retained her previous life's memories as Ichijiku's sister Rena (and knowing her death was the cause of his Start of Darkness) called him an idiot for his goal. She didn't want to be brought back like this, with so many killed. Neko continues, screaming that Kotori/Rena feigned not remembering as further punishment so he wouldn't get the validation he had any success in his conquest to revive her in an immortal body because of the thousands of people he had killed or tortured for that goal. He doesn't deserve love.
Red Herring: Kotori is introduced under circumstances that make her look like another assassin, but turns out to be telling the truth when she calls it a crazy coincidence that she ended up joining a club full of witches. Kana's premonition of her smiling of Neko's corpse just happened to be miss the detail of her not being the one to commit the murder.
Slasher Smile: Has one in a premonition Kana sees, while looking at Neko's dead body. Later revealed to be a misunderstanding.
Survivor Guilt: She only survived to her birthday because her friend Chie had deliberately stopped taking her pills, leaving the last few she had for Kotori.
Stepford Smiler: An interesting subversion. Her best friend, Chie, as she was dying, made Kotori promise to always smile, even/especially when she was sad, because not doing so would only make her feel worse.
Teleporters and Transporters: She can teleport a single person once before hanging up. Interestingly, her power resets kinetic energy, which she unknowingly uses to save a falling Murakami.
Verbal Tic: S-s-s-she often stutters when answering!
What Kind of Lame Power Is Heart, Anyway?: She is initially convinced that her power is completely useless, especially since she can only use it once a day. It turns out it can be put to good use. She notably prevents Neko from being killed by Kikako, and Ryōta from being strangled by a cop. Since it usually requires some preparation beforehand though, it's still relatively impractical.
You Never Asked: She has a nasty habit of not giving Ryouta extremely important information until he himself has already come to the conclusion. Though in a rare case it isn't because she is a Jerk Ass but because she is The Ditz.
A very straightforward escaped Magic User with the ability to regenerate her body to an extreme degree. She's distrustful of humans until Ryouta risks his life to save her. Afterwards, she joins the other Magic Users in the astronomy club, having fallen in love with Ryouta.While in the manga she was an escapee like Neko and the others, in the anime she was one of the seven witches who were supposed to keep an eye on Valkyria but were slaughtered.
Tropes associated with Hatsuna Wakabayashi:
Because You Were Nice to Me: Hatsuna is initially distrustful of humans due to being a witch. However, after Ryouta saves her from the tower, she sees that he really is a good guy at heart, falls in love with him, and saves his life later on.
Black Comedy: Many of her gag scenes are about her being injured or "killed" since she cannot die so easily.
Cassandra Truth: When she first tests Ryouta by pretending to not be able to get off the tower, he does what he can to save her, due to not wanting another repeat of losing Kuroneko. When she tells him her power is Healing Factor, he doesn't believe it because he hasn't seen her use it yet. He also feels she could just be saying it to save him at the cost of dropping her, so throws her back onto the tower before falling off himself though he's saved by Kotori switching places with him right before he hit the ground.
Cast from Hit Points: Hatsuna thinks she has the power to heal others, but only attempted it once, on a cat that got ran over recently. But she says that she stopped about halfway because she started to melt during the attempt. However, she tries it with Ryouta, who was fatally injured in chapter 73, and melts in the process. However, she says she should be okay after her hang up resets after a day or so. And Ryouta does end up recovering after his heart stopped beating.
Clingy Jealous Girl: She starts showing this off in chapter 107, after seeing Kazumi do another Indirect Kiss with Ryouta in the maid cafe by sharing a spoon she fed ice cream to him with. She then ups the ante by putting the cherry in her mouth, and feeding it to him via a kiss. Neither Kazumi or Kuroha seem happy to see that.
Healing Factor: She has a very powerful one, bordering on From a Single Cell. The only things she can die from are running out of anti-death pills or being ejected from her harnest.
Good Thing You Can Heal: Happens quite a bit to Hatsuna due to her Healing Factor. She was the only one of the seven witches assigned to watch Valkyria because of this. She gets cut in half a few times, and nearly melts when attempting to heal Ryouta. And despite being nearly melted, she is still conscious and can still talk. This power also allows her to revive several other characters who get killed.
Loophole Abuse: In chapter 107, Kazumi insists Ryouta try the ice cream special. When he says he can feed himself, she claims that she has to feed him, or else she would get fired for it. Though he lets her do it, he does wonder if she just made up that rule. Hatsuna follows suit with it by feeding him a cherry through her mouth, then claims she's just following the rules about how to serve the customers, much in the same way Kazumi was doing it.
Major Injury Underreaction: Hatsuna takes this Up to Eleven. Her power is regeneration, so it's impossible to permanently kill her. When she gets cut in two by Valkyria, her reaction is pretty much 'okay, walk it off, walk it off'. And in chapter 105, when Ryouta asks her how her day went, she just nonchalantly says that some truck hit her in a remote area.
The Medic: She can heal other people with her power, regardless how bad they are injured.
Rescue Romance: Ryouta going above and beyond to try and save her from falling off the tower causes her to fall in love with him, due to the fact that he was putting all this effort to help her despite not knowing anything about her. Not that Kuroha or Kazumi like that however.
Secret Test of Character: When Hatsuna first meets the main girls, she's skeptical of Ryouta being a reliable human, despite the girls telling her he is. So she purposely climbs up a high tower, and "accidentally" slips off to see if he would only save himself or let her fall. Much to her surprise, he not only catches her, but refuses to let her go, and ends up saving her by throwing her back to the tower ledge, almost at the cost of his own life. She falls in love with him because of how much he cared for her, but her kiss and Love Confession doesn't sit well with either Kuroha or Kazumi.
The Sixth Ranger: She isn't a main character and a member of the group until Kotori's captivity. A month later, she's The Chick.
The chief professor in charge of the magic user experiment. His goal is initially to capture and kill the escapee magic users, and create the perfect alien, but it later becomes clear that he has his own agenda.
Tropes associated with Chisato Ichijiku:
Armor-Piercing Slap: He delivers one to Valkyria after the latter escapes from the witches he sent to watch over her, and it is the audience's first hint that their relationship is complicated when she doesn't immediately kill him.
Badass Normal: A rather subtle one and he's more keen to letting the much stronger Valkyria do the work for him. However when push comes to shove, if he needs to get into action, he will. Slightly more prevalent in the manga.
Big Bad: As the director of Vingulf, he's the one largely responsible for the conflict with the witches in the anime and the first part of the manga series.
Blatant Lies: When a captured fugitive Magic User tells him where the other escapees are, she asks him if he really gives her pills. He says that he promises it. Later, we see that she's dead.
Brutal Honesty: When Valkyria asks him if he doesn't care about anyone else, including her, he very bluntly admits to it.
Bulletproof Human Shield: Played dead straight in episode 13 with Ichijiku Taking the Bullet for Mako - with how much lead Hexenjagd were pumping into him, something should have gotten through, but nothing does.
Even Evil Has Loved Ones: Ichijiku does all the horrible things in the hopes of one day saving his sister (which the head is on Kotori) who died from a disease, even if it means having to kill off all of humanity (including himself) to do it.
Expy: Aside from being a Captain Ersatz to Kurama, Ichijiku is one to Gendo Ikari. Both try to revive a woman they love (sister and wife, respectively), no matter if the world is going to end. And both are admired by a girl they saved.
For Science!: Basically all the research he's been doing regarding the witches has been to try and resurrect his dead sister, whose body is being used currently by an unaware Kotori. He doesn't care what it takes to achieve it, even if it means lots of deaths in the process.
It's All About Me: Subverted. He initially comes off as an emotionless man who cares for nobody but himself and treats others as mere tools. We find out later that in fact he cares for nobody including himself but does care for his sister Rena and is willing to sacrifice everyone including himself in the hopes of saving her. For a pretty specific reason.
Lack of Empathy: Has a fairly distinct lack of fucks given whenever a witch is concerned. His biggest moment comes when a bloodied, pink-haired witch pleads for him to spare her if she told him where to find Kuroha's clique. He promises not to kill her afterwards. Once we cut back to them, we see that the witch was decomposed as a pair of janitors clean away her remains. Ichijiku just keeps staring with a blank face until his bosses call him up.
A Million Is a Statistic: Ichijiku doesn't care how many people die in order to achieve his ultimate goal, to resurrect his dead little sister. He even compares B-rank witches to insects, and feels they're inferior beings that don't have any value.
No Holds Barred Beat Down: Mostly in the manga where he often beats the crap out of people with the most nonchalant face ever. Even more so when he beat Ryota into a bloody pulp when they were trying to rescue Kotori.
Pet the Dog: Ichijiku's one and only pet the dog moment is when he sacrifices his own life to protect Mako in the memory of his sister's final words to him. Miki and Ryouta are shocked and Ryouta even wonders if perhaps there was indeed a little bit of humanity left in him. Unfortunately for our heroes, this causes the already unhinged Valkyria to completely snap.
The Stoic: He shows rarely emotion, to the point that he's barely human.
Taking the Bullet: Blocks the bullets fired by Hexenjagd agents intended for Valkyria.
Tempting Fate: At the end of episode 10, Ichijiku says that he's going to use Valkyria to retreive No. 1107. While the other leaders in the organization protest, he says he's already released her, has seven A-ranked witches specializing in defensive magic to watch over her, so therefore controlling her shouldn't be a problem. Then the scene cuts to Valkyria enjoying the view of the outside for the first time in a long time, and as she looks at her keepers, all of them have been killed by her already.
What Measure Is a Non-Human?: When Ryouta tries to plea for the girl's lives in chapter 71, saying they just want to live in peace, Ichijiku compares Ryouta's argument with an insect arguing for its life towards a human. In fact, Ichijiku considers the main girls to be the same as garbage and a failed product that has to be disposed of.
Why Don't You Just Shoot Him?: Averted in episode 12, when Ichijiku does shoot one of the Hexenjagd operatives that's using an Anti-Magic aura to prevent the witches from using their powers. He immediately has Valkyria warp herself, him, and Kotori out of the observatory.
Would Hit a Girl: He slaps Valkyria at one point to set her straight, and later punches Kotori, Kazumi and Kuroha when they try to interfere with his plans.
An agent of Vingulf who notably accompanies Nanami during her mission.
Tropes associated with Kurofuku:
All Men Are Perverts: When a stranger (he forgot that it's Nanami) ask him to get some money, he is willing to do so, but only if she sells her body. He gives Nanami 1000 Yen (that's less than 10$) when she flashes him her boobs, and later again when she shows him her... armpits.
When Nanami sees into his memories, she's disgusted of what he has done in Vingulf. But we don't know what exactly.
He Knows Too Much: The reason he is told he will be kept under surveillance even after being fired from the institute. To the surprise of no-one, he is disposed of on his way out.
Pet the Dog: Shows genuine guilt when confessing that he caused Skadi to die in vain.
It's implied heavily throughout the manga that he actually does care about the witches but has to hide his emotions on the job or else he'll be the one to pay. He appears to show guilt when having to eject Nanami, allows Kana and Kuroha to live and even the new witches who have appeared remark that they'd rather not have to kill him.
Spared by the Adaptation: He gets killed off in the manga for failing to capture #1107 even after letting their best foresight user die in the effort. In the anime his fate is uncertain, but he's not killed on-screen either. Probably because he survived the murder in the manga, as confirmed in chapter 106.
Token Good Teammate: Played with, while he's not as morally sound as Tsuchiya, he's still far more morally sound than Ichijiku. The manga implies that he's actually a lot nicer than is shown but has to keep his emotions at bay while at Vingulf, something he tells Tsuchiya to do as well.
Took a Level in Jerkass: In-Universe, he once notes that Tsuchiya is very much like he was when he was hired at Vingulf. His idea is that you have to become insensitive (or pretend to be) if you want to survive within it.
A young scientist recruited by Vingulf. Her first assignment is to look after Mizuka before her power is put to use.
Covert Pervert: Well, she would like to be covert, but unfortunately people in the institute don't have much consideration for private life. Freya in particular reveals out-loud and in public the porn sites she visits, the sex-toys she buys, and reads a bit of her yaoi fanfic.
Lima Syndrome: She ends up getting really attached to Mizuka and doesn't want her to die. Kurofuku tells her ouright that showing her emotions like that within the institute is not the best of ideas.
Death Glare: When she's pissed of, which can happen anytime.
Expy: Plot-wise, she's an expy of Dr. Nousou from Elfen Lied. Both are doctors who work for evil organizations and replace their stoic predecessor (Kurama and Ichijiku, respectively) and are more emotional. They also work on projects regarding the strongest Silpelit/Magic User. Nousou creates four clones of Mariko, the strongest Silpelit and Onodera experiments with Hrist, a new Valkyria who surpasses Mako Fujisaki.
Coincidently (or maybe not), Nousou has light hair and his predecessor Kurama has dark hair and wears glasses. In Onodera and Ichijiku's case it's the opposite.
Fate Worse than Death: Before sending a team of Magic Users, she "promises" them that this will be their fate if they are going to fail or disobey her.
"I will make you wish you had been never born into this world, then I will kill you myself! Don't think I will only eject you. I'll make you into venting tools for mad men, humilated nonstop for three years until you die. This isn't a threat. This is a promise!"
Four Eyes, Zero Soul: She wears glasses and is much more evil than Ichijiku ever was. And that's in only two chapters she has appeared.
Hot Scientist: She's an attractive looking scientist with the largest breasts in the series, wears a miniskirt and provides Male Gaze at least twice in her introductory chapter.
Male Gaze: Her introductory chapter has two shots of her well formed butt.
Mood-Swinger: A lot like Mako Fujisaki, Onodera can go from a calm, collected and happy disposition to sporting insane looks and promising a slowly painful death.
Your Size May Vary: The length of her hair varies drastically in her introductory chapter. It reaches her back, than it's Rapunzel Hair, then it's suddenly medium long. This is now her current hair length and it's very unlikely that she has a hair cut in the middle of her way to the conference.
An witch sent to stop Neko and Ryōta when they try to raid the lab to steal death-suppressants. Ranked AA, she has both the power to cut anything with a 6-meter range and to rewind time a minute in the past.
Ax-Crazy: Subverted. Though, she's willing to kill people, she seems not to enjoy it, actually. When she kills Neko, Saori looks rather disappointed.
Clothing Damage: Aside that she deals an important clothing damage to Neko, she also gets some damage and loses her boots and stockings during the battle (manga only, the damage in the anime is minimum).
Hero Killer: Subverted. She does kill Kuroha, and then Ryouta. But because he also stabbed her in the heart before getting killed, she's forced to use her ability to turn time back a minute, so in the end they both are brought back to life.
Impaled with Extreme Prejudice: Ryouta stabs Saori in the back in episode 4, striking her heart in the process. She kills him, but is forced to utilize her spell to turn time back a minute, lest she succumb to death as well. She debates it for a moment, because using said spell would save her, but would also make her vulnerable due to the spell draining much of her power in the process. In the end she uses it, but then is easily captured by Ryouta and Kuroha due to not having much strength to escape or fight back.
Time Master: Saori's second power is to revert time back for one minute. However, it causes her to lock up, which puts her in a bad situation after she reverts time to before killing Kuroha and Ryouta, since she can't fight back or run away.
The Dreaded: Kikako, the AA+ witch chasing after Shino, one of the B witches that escaped with Kuroha and the others. When she's seen in episode 5, even Kuroha, who was determined to help the latter, freezes in fear when she hears that name.
Hellish Pupils: Not only that, her eyes in general are strange (there are scales around them).
Hero Killer: She kills at least three other escaped witches, and one is shown on screen in episode 5.
Oh Crap: Kikako has this look on her face after she's told that while she did get the three harnests she was ordered to, she would also be punished for being caught in the situation she was in, where she was tied up with a brown bag over her head. Episode 7 shows that they did torture her, and she's seen in a slump with blood all over her body.
Unskilled, but Strong: Kikako, the second AA+ magic user we see. Her beam powers are capable of decimating chunks of land, but she can only shoot them in a straight line with a little time lag, that's why Ryouta views her as less of a threat than Saori, who could cut people six metres around her.
Wave Motion Gun: She can fire this from her mouth, but it turns out to be rather Awesome, but Impractical, as it takes a few seconds to charge and dodging it is relatively easy (as long as she doesn't retrain the target's movements).
You Have Outlived Your Usefulness: After Ryouta and Kotori trap her and escape, she gets "interrogated", and is last seen lying on the floor with a lot of blood around her. This despite the fact that she managed to kill at least three escaped witches as ordered to do so.
A AA+ ranked witch with the mission to locate #1107 and the others. She has the power to scan, erase or alter the memories of anyone who crosses her gaze. Which she uses to temporarily escape Kurofuku's surveillance.
Tropes associated with Nanami Tokō:
Anti-Villain: Nanami is not as murderous as Saori, Kikako or Valkryria and she prefers not to murder anyone. She also tries to have a free day where she does not have to use her magic.
Because You Were Nice to Me: Nanami, one of the witches Ryouta and the others meets later, does this for him. Though she has the power to wipe out memories and replace them with different ones, she doesn't do it to him, either because she can't erase his Photographic Memory, or because she chooses not to after seeing what a Nice Guy he is. In the end her harnest is ejected, but not before she's able to transfer her consciousness into him, and provides him with some help later on.
Does Not Like Shoes: She goes barefooted in one of her first appearances, but later wears shoes and socks.
Easy Amnesia: One of Nanami's powers is to erase people's memories and if needed, rewrite them. This way she can erase her presence from their minds as if they never saw her before, or she could make them think she was their most important person they've known for years, even if she just met them.
Fake Memories: The aspect of her power that she kept hidden to the lab. She uses it to make people "remember" her or turn them against her enemy.
Girlish Pigtails: How she wears her hair. They also totally dispose her Harness.
Heel-Face Turn: After learning about what friendship is, she becomes friends with the main characters. Unfortunately, not long enough.
I Just Want to Have Friends: When she's first freed from the lab to search for #1107, she immediately tries to do things that she wouldn't of been able to, such as eat a lot of sugary foods. She later sees a bunch of girls walking together and having fun, and feels a bit lonely as a result. Then Ryouta and the other witches offer to be her friend, though this doesn't last because she's ejected and killed moments after meeting up with them.
Laser-Guided Amnesia: She can give this at will to people, from simply making people forget her to mentally turning them back into 5 year olds.
Loophole Abuse: Nanami's handler Kurofuku wears sunglasses even when indoors because she can't read a person's mind if their eyes are blocked from her view. However, this doesn't prevent her from wiping and rewriting other people's memories around him, and she uses them to attack her Kurofuko in order to expose his eyes to her.
Mind Rape: From wiping out their memories from until the age of five to implanting memories to believing a guy raped his sister who doesn't even exist. This ranges from Hilarity Ensues to Fridge Logic. She attempts to do this to Ryouta as well, but it doesn't work, either due to either his Photographic Memory surviving the mind wipe, or Nanami choosing not to erase his memories because she saw something in him (he said he'd trust her and shows his eyes to her instead of looking away), or possibly both.
Spirit Advisor: Becomes this to Ryōta after she is ejected and inserts her own memories into his brain just before dying.
Sweet Tooth: She claims that her magic requires a lot of sugar from her brain, that's why she often need to eat sweets. If it's true or just an excuse to eat some sweets is detable, but she really loves sweets.
Terrible Artist: Nanami's attempt to recreate what the police remember seeing Ryouta as looks nothing like him. In fact it looks more like an alien than a person.
Ranked AAA, this sweet girl has a power of foresight far surpassing that of Kana, not only because her visions are far more accurate, but also because she can interact with the future she sees. Like Kana though, she is completely paralyzed, as well as half-blind and almost deaf. Like Nanami, her mission is to spot "#1107" so that the institute can capture her.
Tropes associated with Skadi:
Adapted Out: Her arc was completely skipped in the anime.
Dreaming of Things to Come: Her visions effectively function like some kind of conscious dream, where she is in full health and can run all she wants, but also talk to people in the future. She actually uses this to help Kazumi, because while dedicated to her mission, she doesn't want anyone to die needlessly.
Evil Counterpart: To Kana, who has the same powers as her, just weaker. Well, more antagonostic counterpart, as she's not evil at all.
One of the strongest, next-generation witches, called Valkyria. She looks just like Kuroha (with the exception of having white hair), but couldn't be more different if she tried. She has a sadistic, sociopathic personality, and would kill people on a whim, with a smile on her face. The exact nature of her relationship with Neko is not elaborated upon, since Neko herself can't remember her. Kuroneko, on the other hand, refers to her as 'Onee-chan', and fully remembers her.
Tropes associated with Valkyria:
Ax-Crazy: She's the most craziest character when it comes to kill people.
Badass: Currently the most badass villain of the series, being a lucky winner of Superpower Lottery. It's more prevalent in the manga, though, where she proves how destructive and strong she really is and how difficult it is to kill her. The battle in the manga between Valkyria and Kuroneko reaches even DBZ levels.
Black Comedy/Bloody Hilarious: When she tricks a man into a shower so she could kill him with a thought and not make a mess, her first thought after killing him is she just ruined her chance to take a shower.
The Dragon: To Ichijiku. She's extremely loyal to him and is his most powerful tool.
Dragon-in-Chief: She's much more dangerous than Ichijiku, but she's loyal to him.
Dragon Their Feet: After Ichijiku's death, she continues to destroy the world for him.
The Dreaded: A double S ranked witch. Kana tells Ryouta that she can utilize eight forms of magic, one of which is the power to detect other witches. So naturally when she shows up unannounced, it puts quite the Mass "Oh, Crap!" trope into use.
Even Evil Has Standards: While Valkyria is seen killing random people and witches off randomly in chapter 59 and 60, she for some reason won't hurt Kuroha and by small extension, the other witches in the observatory. She also spares a random girl who was walking home with Hatsuna, who turns out to be a witch after the latter reveals where her pills are hidden away at.
Hero Killer: Valkyria kills several people, such as the police who tried to stop her, to even some innocent people who just happened to be in the same area as her when she wanted to look at some scenery alone. She also kills some witches offscreen to take their pills away from them, including seven that Ichijiku sent to watch her.
Mood-Swinger: The speed with which she goes from "murderous intent" to "tearful apology" towards Ichijiku is quite impressive. At times she appears as innocent as Neko, but can bear a Slasher Smile the second after.
Standard Female Grab Area: Kuroha does this to her in chapter 60. She then leaves, either because Neko would have been able to affect her directly with her magic, or out of respect or fear for her.
Stockholm Syndrome: She was in captivity by Vingulf's researchers, but Ichijiku saved her from a dangerous experiment that was going to fail. Since then she's in love with him, even when she knows that he does not feel anything for her.
Superpower Lottery: Possesses several types of different powers, including teleportation, being able to dismember people with a thought, detect other witches and even create antimatter. And the number of her powers increases over the time, having eleven powers until her death. It takes unlocking Neko's own Superpower Lottery abilities to defeat her.
Yandere: Towards Ichijiku. After his death, she decides to kill all humans.
A AAA technopathy user, who spends her days reading manga and playing games in her room. Tasked with locating Chisato Ichijiku after he betrayed the institute and kidnapped #1107 by himself, along with Valkyria.
Three magic users send by Onodera to eliminate Kurofuku, after Vingulf learned of his miraculous survival.
Tropes associated with the trio:
Asshole Victim: Rurumi, according to Kikka in chapter 114. She tells Kana that Rurumi was kind of a jerk before her drasil awakened due to attacking the two earlier. Hence why it so easily turned on its former friends. Despite that, Kikka believes Kana wouldn't be the same since she did everything she could to protect the former when the drasil showed up. So if Kana's drasil did show up, it wouldn't eat her right away.
Big Damn Heroes: Misaki does this in chapter 113 to save Kana and Kikka from the drasil in the hospital. She wasn't around during the earlier chapters because she was following other people at the hospital at the time and was unaware of the drasil showing up until she came back to where Rurumi and Rin were at.
Eaten Alive: Rurumi's body is eaten by the Drasil, but she's still technically alive, since the Drasil contains her soul. Then Rururmi eats Rin.
Green-Eyed Monster: In chapter 109, the three girls are clearly jealous of seeing Kana not only moving around, but also talking to Kitsuka and eating a crepe, and enjoying life while they're stuck with Vingulf. Rurumi, the smallest girl, then uses her Voodoo Doll on Kana, and Kitsuka as well in a fit of jealousy. One of the other witches later tells Kana that she isn't their target, and even wants to join whatever group the latter is with.
I'm Melting: Misaki ends up remotely ejected when her beacon is triggered.
Off with His Head!: Rin suffers this fate in chapter 111 by Rurumi, or rather, the drasil that awoke inside of her.
Reasonable Authority Figure: Rin. She tells Kana that they're not after her, and instead are targeting a human. She also says she won't report having run into the latter, and even says she wants to join Kana's group after they finish their mission.
Stupid Sacrifice: Rin sacrifices herself in exchange for Rurumi's Drasil promising not to eat anyone else. Kana calls Rin out for it since the Drasil is not rational, and Kana is right.
Take Me Instead: Rin offers herself up to be eaten in exchange for "Rurumi" promising not to eat anyone else.
Voodoo Doll: Rurumi uses this on Kana and Kitsuka in chapter 109, after getting incredibly jealous at the normal life Kana seems to be having while they're still witches stuck with Vingulf.
We Hardly Knew Ye: Rurumi's Drasil hatches and devours her corpse right after entering the hospital. She then bites Rin's head off when the latter tries to protect Kana. Then, Misaki ends up remotely ejected right after the Drasil is dealt with.
Weaksauce Weakness: Rurumi's Voodoo Doll allows her to manipulate the body whoever she points it at. However, if she loses her doll, she's completely helpless. Kana points out after the former tossed her doll into the air while in control of Kitsuka's body, and this allows her to grab said doll, and help Kitsuka land back down safely.
Like the name suggests, Hexenjagd is an organization that hunts Magic Users, whom they call "witches". They are also opposing Vingulf. Members of them were originally researchers of Vingulf, but after discovering their inhuman goals, they left it and founded Hexenjagd.
Tropes associated with Hexenjagd in general:
Cavalry Betrayal: The Hexenjagd reps save Kuroha and the others from Ichijiku in chapter 73/episode 12. But then they tell them at the end of the chapter that they have to kill them because they really are monsters. In chapter 74 they explain to Ryouta that the girls are really just those alien slimes they've seen inhabiting the bodies of the girls. And sooner or later, those things will emerge from the girl's bodies and turn into something that's definitely not human. So they figure it's better to kill them now. But Ryouta manages to talk them out of it, largely because the girls only have about a week supply of pills at best, and one of the reps says they're unlikely to emerge in such a short time and their bigger priority was hunting down number 1107, Kotori, who was kidnapped by Ichijiku when he fled.
Church Militant: Their outfits resemble those worn by Christian clergy, and Miki and Initializer pray at the start of episode 13.
Enemy Civil War: Hexenjagd is an organization that comprises of researchers from the main organization that's doing the research and experiments on the witches. While they are fighting the main organization, they are also hunting down witches as well, which puts them at odds with Ryouta's group.
A Lighter Shade of Black: Or possibly even a dark grey. Unlike the main organisation, they can be reasoned with, and while they're highly suspicious of witches, they can be persuaded to let the harmless ones live. They also tend to keep their word and it's a telltale sign that going What the Hell, Hero? on them actually works and they've been shown questioning the morality of their own actions several times. As far as (reluctant) allies go, the protagonists could do worse than Hexenjagd.
An Offer You Can't Refuse: Hexenjagd makes one to Ryouta in chapter 79. They want Kazumi's help hacking and finding out where Ichijiku is hiding Kotori so they can eliminate her, or more specifically the "Grane" or "alien life form" inside of her, which is capable of destroying all humans on Earth. In exchange, they'll reveal the formula on how to create the death suppressant pills.
Only One Name: Full names of the members have to be revealed yet.
Out of Focus: Their role in the anime is drastically reduced, whereas in the manga they are quite active when Ichijiku and Valkyria are running around.
Villainous Rescue: Kuroha and the others are saved from Valkyria in chapter 72/episode 12 by the appearance of representatives from Hexenjagd, a group of witch hunters, but also opposes the organization Ichijiku is representing.
Apparently a high-ranked member of Hexenjagd. Not much is known about her yet.
Tropes associated with Miki:
Nun Too Holy: Though she dresses like a nun, she hardly acts like one, and often threatened Ryouta and the other witches.
Reasonable Authority Figure: She's smart enough to realize that killing the witches hiding in the observatory wasn't worth the effort after hearing that they were going to run out of pills in a week or so anyway. She also helps Ryouta out when taking down Ichijiku and Valkyria.
A researcher of Vingulf, who actually works for Hexenjagd. During the transport of the "failed" magic users, Hexenjagd failed to capture #1107 and Akane accidently died there, but she was able to give Neko Kuroha the terminal of Hexenjagd and the alien embryo.
An escapee who has contact with Kazumi. She possess the power to understand animals.
Tropes associated with Shino:
Adaptational Heroism: In the manga, she's just a minor character who contacts Kazumi to ask for help, but is killed by Kikako because Shino runs panically away, being an easy target to hit. This is changed a little bit in the anime, where she meets a little black cat, allowing her to display her magic power, and ultimately she sacrifices her life for this cat.
Ascended Extra: The anime gives her a little bit more screentime and reveals her magic power to the audience. The circumstance of her death is changed to give her a bit more personality.
An escapee and friend of Kotori. Because their anti-death pills were running out, but Kotori's birthday was sooner than hers, Chie decided to sacrifice her life by refusing to take any pills, so Kotori can experience her 16th birthday. Chie was a Technopath like Kazumi and helped Kotori to enter in a school, which is coincidently Ryouta's.
Tropes associated with Chie:
Heroic Sacrifice: Kotori's friend Chie does this for her. Their birthdays were coming up, but due to the lack of pills neither one of them would live long enough to see it. So Chie decides to forgo her pills so that Kotori could at least live to see hers, especially because the former's was a week after Kotori's, so she definitely wouldn't have lasted even with Kotori's share. Kotori feels really bad about this, and attempts to let herself die as well, but Ryouta and Kuroha manage to convince her to survive, if nothing else, to live to see Chie's birthday and wish her friend one.
Only Friend: She was Kotori's first friend and only friend before Kotori met the other main characters.
Determinator: He is prone to having motion sickness, so he cannot get into any moving object without getting sick. This did not stop him from walking from his hometown to the college over a hundred miles away.
Eyes Always Shut: Zigzagged. He's seen with this eyes shut and open on occasion.
For Science!: Kogorou is the good variant of this trope, but he is slightly crazy in his normal work and very hard to convince.
Insufferable Genius: Played Up to Eleven. He tells Ryouta that he's been offered a job by a prominent American pharmaceutical company, but doesn't want to leave Japan, and says if they wanted him that badly, they should open up a lab in town for him. Ryouta also didn't want to have to talk to him at all, but because of his expertise, he ends up visiting him to see if Kogorou can recreate the pills for the girls.
He-Man Woman Hater: He can't understand how women work, that's why he hates them. That doesn't stop him from helping Ryouta's witches anyway.
Secretly Wealthy: Has a lot of money in several accounts due to being very good in the stock market. This comes in very handy later on when Ryouta needs a new hiding place for the girls after the observatory is compromised.
Wham Line: He tells Ryouta that he needs six months or longer to reproduce the anti-death.
Worthy Opponent: To Ichijiku. When they were still in college studying for their degrees, Ichijiku was the ones always getting the higher marks, and he respects him.
Voiced by: Mariko Honda
A girl who Ryouta tutors in his spare time and who has a crush on him. Nicknamed Kikka.
Tropes associated with Kitsuka Hatsuda:
Action Survivor: She becomes one after spending time with Kana, and learning more about witches first hand in chapter 108..
A-Cup Angst: She has even less of a bust than Kana, who isn't terribly large herself. When she notices the difference in chapter 108, she's not very happy about it.
Body Horror: She witnesses a witch melting in chapter 113. Though she doesn't say anything at the time, she has a horrified look on her face as it happens.
Clingy Jealous Girl: Knowing that the guy she has a crush on has suddenly gained many female friends makes her this.
Expy: If you compare with Elfen Lied, Kitsuka being a ordinary girl with no traumatic or dramatic backstory, being a brown-haired Tsundere who is in love with the male hero, she's this to Yuka. Adding Kitsuka's middle school age and her Secret Keeper status, she's also one to Mayu.
Go Through Me: She attempts this against the drasil in chapter 112/113, if nothing else, as a means to delay it eating Kana after having killed and eaten several other characters already. It works about as well as you'd imagine a teenage girl with a mop as a weapon against a giant monstrosity. Fortunately Misaki saves her in chapter 113, moments before Ryouta and Hexenjagd arrives to destroy it.
Oh Crap: Kikka has this look in chapter 103, along with Kana, when they both see each other at the former's middle school, which Kazumi transferred her to since the latter was able to move around again.
Out of Focus: In the anime, her appearance and role is vastly reduced due to Compressed Adaptation limitations having only 13 episodes to work with. She only shows up briefly when Ryouta is tutoring her, and again when Nanami brainwashes her to lead Ryouta to her. She also doesn't show up by the beach when the main cast goes there.
Precocious Crush: In episode 7, when he leaves the tutoring session a little early, she asks if he has a date. He then tells her to call him "sensei" (teacher), and says if she has time to has pointless questions like that, she should be studying more. After he leaves, she blushes and says it's not a pointless question.
Secret Keeper: In chapter 109, Kana reveals the existence of Magic Users and Kitsuka experience Rurumi's magic.
Super Drowning Skills: She isn't a good swimmer. Kana later gives her some ribbing for it in chapter 108, particularly as she picks up swimming right away, and ends up helping Kitsuka to swim. However, chapter 112 reveals that she has an irrational fear of water due to nearly drowning several years earlier. Made worse by the fact that she wasn't in very deep water either, but slipped and lost her balance.
True Companions: She completely trusts Kana after hearing that the latter will protect her, and Kitsuka would give her life for Kana.
A Twinkle in the Sky: Rare non-comedic example. This happens to her in chapter 109 after demanding proof from Kana about witches, and suffers this from Rurumi, a magic user still associated with Vingulf, the organization Kana and the others ran away from.
Vitriolic Best Buds: Kind of becomes this with Kana after the latter regains the use of her body and joins her school. And definitely after they both survive the hospital drasil incident, the lengths they went through to protect the other.
What the Hell, Hero?: She does this to Kana in chapter 114 when the latter doesn't show up at school after the hospital drasil incident in the previous chapters.
