"Long ago - well, not really, but shush - there lived a boy named Yamada. Yamada was what you would call a problem child. All the students at his school were afraid of him. Then one day... Something happened and Yamada was never the same."
Yamada-kun to 7-nin no Majo (山田くんと7人の魔女), or Yamada and the 7 Witches is a shounen supernatural romantic comedy manga, with elements of ecchi and gender-bending by Miki Yoshikawa (who was an assistant to Hiro Mashima, explaining why the artstyle bears some resemblance to Fairy Tail, as well as the creator of Flunk Punk Rumble), currently being serialised in Weekly Shōnen Magazine.Ryuu Yamada is a second-year student at Suzaku High. Ryuu is always late for school, naps in class and gets abysmal grades. The beautiful Urara Shiraishi, on the other hand, is Suzaku High's brightest student. One day, without explanation, their bodies are swapped! Ryuu ends up in Urara's body, and Urara in Ryuu's. Thus begins Yamada's journey into the world of Witches and Suzaku High's mysteries.A Live-Action TV show began airing on August 10th, 2013. Now also in animated form, though only as a promotional video for the manga. An anime series has been confirmed, but is still in the planning phases, after the video gained one million views.
This manga provides examples of:
Aborted Declaration of Love: Nene, believing she's going to get her memory wiped out again, tries to give one to Yamada. At the same moment, he obliviously decides he's too cool to let her finish.
Absurdly Powerful Student Council: The council president is actually aware of the Witches in the school and keeps them in line, and two of the Witches actually are on the Council. Moreover, according to Tamaki, the power the Council holds is absolute. If you're nominated for a place inside this Council, you can't refuse. And Rika the Seventh Witch serves as their enforcer, erasing memories as needed.
Accidental Kiss: Actually important in the first few chapters for puzzling out the mechanics of swapping bodies.
Adult Fear: The series' Darkest Hour comes when Yamada's friends lose all their memories of him and start treating him like a stranger. It's not the unrealistic Laser-Guided Amnesia that's supposed to be the scary thing here - no, the scary thing is the (unfortunately) more realistic scenario of a person who has good friends and - as Yamada himself expresses it - "lives the high life", but suddenly becomes all alone and feels how painful loneliness is. A bit of Fridge Horror comes in from realizing that Yamada actually lived this way for almost a year before the start of the series.
Adults Are Useless: The only adults seen in the series are some of the teachers, but they don't seem to hold that much power as the student council is more or less governing the school. The students always solve their conflicts by themselves, never asking any adult for help (except for when they needed a teacher who had the key to the old Supernatural Studies clubroom), so it's not known how much the teachers could do if they actually got involved in the plot. Otherwise, the series suffers from a case of Invisible Parents.
All Men Are Perverts: While most are, Yamada is never shown using the swap or charm powers in perverted means.
Armor-Piercing Question: Yamada asks Rika the Seventh Witch why did the President order Asuka to switch bodies with Urara if he had absolute faith in Rika and her abilities? Why didn't he even tell her about this plot? Could he not trust her? The normally controlled questioned gets flustered.
Artifact Title: Subverted and later played straight. After the ritual that erases the original witch powers, it seems - for a short while - like the series is turning into a simple Slice of Life comedy about Yamada's relationship to Shiraishi and work in the student council and not about any witches. The subversion comes when it is revealed that seven new witches have arised at the school, and the second part of the plot kicks in, now that the main cast have to find the new witches. However, in chapter 110 it is revealed that some of the "new" witches had their powers before the ritual which means they are not the new seven witches. This means that there at least eleven witches at the school, making the "seven" part a bit obsolete.
Aww, Look! They Really Do Love Each Other: Despite her cold demeanor, Shiraishi really does care about Yamada and truly trust him, to the point when she does not even bother to ask him why he wants to swap into her body. This is further demonstrated when she demanded to include him in her camping group or said that she enjoyed school now because of him. Yamada himself admits that he is in love with her.
Bi the Way: Miyamura has no problem flirting with Yamada or hitting on all the girls. Especially when under Yamada's love power, which Nene points out doesn't change people that much when it's used on them.
Sarushima just likes kissing. She doesn't really care who she does it with.
Bland-Name Product: Happens several times with the food and drinks the characters are consuming. Usually you have to look closely into the background to see the altered brand name, but one more obvious and hilarious example is in chapter 94 when Shiraishi brings Yamada snacks and coffee of a brand called "Starsocks". The logo has the Starbucks mermaid replaced with a sock with a star on top. Itou also uses a computer of the brand "Mec".
Blatant Lies: Itou trying to convince the Supernatural Club of her psychic abilities (by physically bending a spoon) or her possessions (a photo of a UFO fake on a string and a rock).
Sarushima and Noa's power respectively. Seeing futures that were meant to happen and traumatic past isn't the best thing.
Rika's is NOT happy to have her power as no one will be able to remember anything about her at all.
Boke and Tsukkomi Routine: When Yamada plays tsukkomi some of the boke behaviours he is up against are sometimes enough to make his eyes bulge. Occasionally Yamada's apparent idiocy makes him the boke.
Book Dumb: Yamada, to a T. He's far from the best student and has trouble grasping complicated concepts, but he's surprisingly observant and intuitive.
Break the Cutie: Yamada gets hit by this hard after meeting the 7th Witch. Instead of losing his memories, everyone's memories of him gets replaced. He's alienated by his former friends as he is nothing but a stranger to them now. He asked Shiraishi out, only for her to reject him because she claimed she loves someone else. Itou claimed that she was in love with some other club member because they committed acts that Yamada actually did (like accidentally kissing Shiraishi while falling down the stairs or catching bathroom peepers). And after all those months of cultivating a loving relationship with her too. Then again, this is Itou we're talking about who also claimed she might be in love with Itou.
Even before that, there is his backstory with Ushio. Your best friend jumps into a fight, making you feel obliged to do the same only for him to turn around and lie that you were the only one fighting, resulting in a suspension from school and turning you into the school's outcast?
Brought Down to Normal: When Yamada completes the Witch Ceremony this was his desire. He wished not for the memories to be turned but the Witch Powers to be gone from the school. However it's later revealed that, those powers were replaced with slightly similar ones.
Butt Monkey: Yamada. The other characters act as comic relief as well, but Yamada seems to get most of the slapstick, the harshest jokes and the blame directed at him.
Buxom Is Better: Shiraishi is very beautiful, perfect, and as Miyamura's noted, has E-Cup breast.
If the latest beach picture can be used as a reference then this applies to Nene, Maria and Rika as well.
Also Miyamura's new Vice President, Arisugawa.
The Cameo: Daichi Shinagawa and Seiya Chiba, of Yoshikawa's previous manga, Flunk Punk Rumble, make a brief appearance as adult teachers in the first chapter.
They also appear in the manga PV along with Hana and Rinka, but still high school-aged.
Cerebus Syndrome: Rika's arc is darker than the arcs before, due to the several factors. All the glory Yamada managed to accumulate during the former arcs disappears in an instant, as his old friends forget everything about him, and he is all alone again. Yamada's old friends in the Supernatural Studies Club are drifting away from each other due to Yamada not acting as the link of the group more, which affects especially Shiraishi. Several characters' (Leona, Rika, and Yamazaki) Dark And Troubled Pasts are delved into, and we see the effect the Wistful Amnesia has on Shiraishi and Yamazaki. There are possibly more Tear Jerker moments and Hope Spots in this arc than in all of the 65 chapters before. Fortunately, it all ends well, and the series goes back to its usual light-hearted mood in the next arc.
Character Development: Not just a tool for characterization but actually a plot important point. Yamada's influence and help encouraged the Witches to change for the better. With their memories of him gone, all the Character Development made has been lost, with the Witches going back to their old, and, for four of them, wicked ways.. It does a toll on Tamaki when he realizes that, helping him to grow too.
Charm Person: The power of Nene Odagiri, who makes anyone she kisses fall in love with her. She then uses them to her advantage. Turns against her when Yamada uses the same power on her.
Chekhov's Gunman: Asuka Mikoto debuts before most of the characters and appears from time to time as part of the Student Council, but she's not revealed to be a witch or even named until much, much later.
Nene Odagiri is a less extreme one. Though she's immediately named at her debut also as part of the Student Council it still takes some chapters before she's revealed as a witch.
Chick Magnet: Miyamura is a "straight" example, even if he's not in the slightest interested by the girls who squee over him, preferring to sexually harass Yamada instead. He certainly doesn't mind a shot of panties though.
Subverted often with Shiraishi. Whenever she seems like she's a bit upset about Yamada's interaction with other girls, it's actually her being concerned about other things, such as people finding out about his secret power. Or at least that's what she wants him to think. It is played straight in Chapter 60, when she pouts over him choosing to partner with Itou instead of her.
Rika the seventh witch, was revealed to be this towards Yamazaki when he was just a normal student but close to Leona, Miyamura's sister. So she set him up by telling him she was the seventh witch to ensure he would forget about Leona with her memory wiping powers.
Clueless Chick Magnet: Yamada has no idea when chicks are into him. Isn't that right Odagiri? This is lampshaded by Tamaki.
Comic Book Time: The narration states that the story starts "not too long ago", so since the first chapter came out early 2012, the in-universe year is probably 2010 or 2011. Yet, when the Supernatural Studies Club visits Itou after New Year, she has a PlayStation 4, despite that only around eight months have passed since the start of the story, making it January 2012 as the latest possible time. On the other hand, that would explain why Tsubaki is so surprised that Itou has one...
Cool Big Sis: Miyamura's older sister Leona. When she drops her shields, she shows she has a great depth of feeling but is also scared of the 7th Witch. When she realizes her brother was victim to her, she agrees to help Yamada fix everything.
Yamada's sister thinks Nene is this.
Crazy Jealous Guy: Ushio does NOT like it when Nene kisses other people. Even if she's just doing it to cast her spell.
Cursed with Awesome: Some of the Witches are unhappy with their abilities. The most obvious example is Maria who wants to get rid of her ability. The reasoning being is that her power takes the fun out of her life and it's impractical to have a relationship with someone if her power activates every time she kisses.
Cute and Psycho: Asuka Mikoto after Yamada uses Nene's power on her. She wasn't exactly sane before but the trope was played Up to Eleven during that time.
Yamada: Sh-She's not just crazy... she belong in an asylum!
In fact, all major male characters except for Yamazaki give off a slight delinquent vibe when they are introduced (though it disappears in the case of at least Tamaki and Miyamura). It's quite obviously an Author Appeal with how the series has no traditional Nice Guys.
Demoted to Extra: Incredibly, after the original witch powers disappear, and a new student council is formed, almost all of the original main cast lose their place in the main cast, with only Yamada, Miyamura and Odagiri staying prominent. Even Shiraishi, who was nothing less than the female protagonist, has seemingly been demoted to just "the hero's girlfriend" which Yamada hangs out with and thinks of now and then, but otherwise isn't seen much. Tsubaki and Itou have almost disappeared into the background. Of course, this is only a short way into the second part of the story, so it can still change.
Do Not Do This Cool Thing: The arc about the Telepathy Witch is set around remedial exams which both Yamada and the new Witch have to take. They use the telepathy power to cheat and make the grade with the help of all of Yamada's friends. After the exams an author's note says "Please don't cheat."
Do Well, But Not Perfect: The first time Yamada asked Shiraishi to take some exams in his place, she scored just one point below perfect just to show off.
The new Mind Control witch is suffering from this. She swore she would end her control over her teammates once the one game was over but hasn't yet. And now is getting to the point she is ordering another student to do her homework and shutting up another who yelled at her for making someone do her work.
The new Mind Reading witch subverts this. She may use her power to peak into people's minds but she isn't lost to it. However, when Yamada copied it, he was. He nearly lost himself to the power until the witch went to the Memory Erasing witch to talk some sense into him. He does listen to them and realizes how bad he nearly got.
Easily Forgiven: To cite Miyamura, Yamazaki was the "smarmiest bastard he ever met" and apparently injured people to end up a club. During his time as the President and Yamada's main antagonist, he enforces ruthless policies, wiping minds on the go and allowing Asuka to lock Yamada down and torture him. It's never mentioned again and once the arc was over, he became an ally, giving some data and insight. One has to wonder the influence Leona actually had on him. Or if he was corrupted afterwards.
Emotionless Girl: Shiraishi seems to be this on the outside, but she's more emotional than most people would think.
Even the Girls Want Her: Nene finds herself attracted to Shiraishi in Chapter 116. She theorized that it was perhaps because she was in Yamada's body and therefore inherited his emotions. Or perhaps because Shiraishi acts differently towards Yamada.
Everyone Is Bi: Most characters have no qualms kissing someone of the same sex. Miyamura likes Yamada to begin with, which is kicked into overdrive when he is under the influence of Nene's powers. Yamada is fine with kissing himself, or random guys at the cultural festival. A few characters are explicitly straight or at least prefer the opposite sex more, but they are the exception and not the rule. A lot of this is for pragmatic reasons, however, as kissing is the way to utilize their witch powers.
Fantastically Indifferent: Everyone is pretty chill on the Witches power despite the supernatural element in an everyday setting. You would believe at least one guy would alert the medias but nothing happens, nobody freaks out, and the mystery stays contained inside the school. As an example, see Itou deciding, upon discovering she got a new body, to practice some martial moves and deal with delinquents.
Flashback Nightmare: The power of Noa, which lets people see the traumatic events in someone's past after they fall asleep.
The Four Gods: The school is named after Suzaku, the Vermillion Bird. The narration in the first few chapters reveals there are also Seiryu, Byakko, and Genbu high schools. In fact, Miyamura transferred from Seiryu high.
"Freaky Friday" Flip: What kicked off the plot. It was thought to be Yamada's power, but turned out to be Shiraishi's instead.
Foreshadowing: Miyamura easily spots the thread and makes Yamada reveal his and Shiraishi's secret. Much later it's revealed that the whole reason why he transfered himself to Suzaku High in the first place is because he knew about the Witch powers.
Same with the President Yamazaki, he easily recognizes Yamada and Miyamura in female bodies, but later it's established that the Councll is privy to the witches' existence.
Friendless Background: Yamada, Shiraishi and Itou all qualify. It's not unlikely that Miyamura qualifies, too - even though he has always been much more popular than the aforementioned three, he didn't seem to have actual friends as much as he had tons of fangirls and tried to suck up to Yamazaki.
Funny Background Event: Of The Comically Serious type. In the chapter where Itou joins the Supernatural Studies Club, she tries to impress the club by showing off her "supernatural" possessions (which are just things like normal rocks, spoons etc.). Yamada and Miyamura listen to her and have several funny reaction shots to her Blatant Lies, while Shiraishi doesn't join in. Then, in one panel, she appears in the background, reading a book and looking as somber as ever. Apparently, Itou's antics were so stupid that the serious Shiraishi didn't even bother to react, just retracting to the background instead.
Gender Bender: The first switch is with Shiraishi, Yamada's female classmate who sits next to him. As they are joined by more students they all start trying out the body swapping.
First Law of Gender Bending: Averted. Gender Bending, or more precisely "Freaky Friday" Flip, is mostly a mean to an end and it gets the most usage only because it's the Witch power most readily available to the main cast and a relatively harmless way to protect them from other Witch powers as two of them can't affect the same target at once.
Second Law of Gender Bending: Also averted. Characters don't markedly enjoy Gender Bending more than they want to take another's place or vice versa. E.g. Yamada asking Shiraishi to take an exam for him or him using her body to outwit someone else.
Generic Cuteness: In line with the Only Six Faces trope. Miyamura is supposedly very handsome, while Yamada is implied to be plain or even a bit ugly - at least it isn't his appearance that makes the girls fall for him. But they both have the same face and body, except for Miyamura being maybe an inch taller. The same with Shiraishi and Itou: Itou is stated to be pretty, but not out of the ordinary. Shiraishi is seen by many as the school's most beautiful girl. They also have the same face and similar bodies (though Shiraishi has bigger breasts than Itou so at least there's that difference).
Geometric Magic: The ceremony with the seven witches involves them standing in a circle equidistant from each other and the castor in the center. Somewhat subverted in that the seven witches only need to form a circle while holding hands. Rika guesses that some previous generation drew the circle for extra style points.
Going Commando: Rika Saionji states that she wear any since the day she forgot to put some on.
Gonk: The make-up exam teacher who looks more like a dog/seal with a bob cut than a human.
Green-Eyed Monster: The seventh witch was in love with Yamazaki, but himself was in love with Leona, to the point he became President to protect her club. Unable to woo him, she decided (in a sense) to Murder the Hypotenuse by wiping all memories of her, making him forget why he became President, snowballing in the whole fiasco we know of. It's likely nothing would have happened if it wasn't for her jealousy.
Hair Decorations: Shiraishi can always be recognized on the black, X-shaped hair pins she wears in her hair above her ears.
Heel Realization: Upon seeing Leona, Yamazaki felt a surge of emotions he couldn't understand and realized his memories were erased and so wanted Yamada to perform the ceremony to recover all the memories.
Nene's plans fall apart when her power is used against her.
The President having everyone's memory erased of Yamada ends up coming back to bite him as the Witches abuse their power and go back to their old ways.
How Do I Shot Web?: It took the characters a lot of time, creativity, experimentation and plain luck to learn how the Witch/Witch Hunter powers work. For example, only after Yamada copies another Witch power, him and Shiraishi figured out that she was a Witch the whole time. Not even the Student Council seems to know every quirk about the Witch powers.
One time Yamada gets to be the one to remark on the hypocrisy of Nene making fun of Midori because of her big boobs by pointing out that it's not like she's small herself. That shut Nene up, though not for the reason Yamada thinks it did.
I Just Want My Beloved to Be Happy: Once her memories are restored by kissing Yamada, Nene realizes she's in love with him. Yamazaki realizes this as well and makes her an offer to be with Yamada if she stops helping him gather the witches. She confesses to Tamaki that she told Yamazaki to stuff it because she knows that Yamada is in love with Shiraishi and she'd rather enjoy what time they have together than be a nuisance to him. True to that, she doesn't try to stop him when all the memories have returned.
I Just Want to Have Friends: Or at least an embarrassed Tamaki is implied to be this when Yamada offers him a chance to join the Supernatural Club after they find a way to restore everyone's memories.
Part of it might have had to do with her academic excellence or it could have also been her stoic personality. It's never clearly established why she was being bullied.
Invisible Parents: Parents are never seen (except for Itou's mom in one extra chapter, but at least they are never seen in the main story) and almost never mentioned except for a couple of offhand lines here and there. When a character's home is shown, the parents are always absent no matter the time of the day. When more than one character is needed to be at the home for plot-related reasons, it's always a sibling.
It Only Works Once: Rika Saionji's amnesia power only works on a witch once. No one, not even Rika, knew this until she failed to alter Nene's memories a second time.
Miyamura revives the Supernatural Studies Club with Yamada and Shiraishi so they can switch bodies in private. They get more members later on. They discover that a previous batch wrote notes about the witches, and they have yet to recover all of it.
The Archery Club headed by Karen Kimishima. Much of one arc takes place in its clubroom, though ultimately she wasn't a witch.
Meiko Otsuka and her two friends comprise an Anime/Manga Club and make doujinshi.
Asuka and Ushio were last seen in the Chess Club, implied to be planning something.
Jerkass: Nene Odagiri started out as this, but she starts changing. Noa and her friends aren't the nicest of people, but they do care about each other.
Same can be said for Ushio, but all of those actions were out of his love for Nene.
Jerk with a Heart of Gold: Yamada may be a delinquent, but he'll go out of his way to help people in trouble. Even if said people antagonized him.
Honestly, this trope applies to most characters in the series - it's only a selected few who are outright nice or outright jerks. Shiraishi, Miyamura, Itou, Tsubaki, Odagiri, Ushio, Tamaki, Leona and several of the witches have acted really unpleasant at times, but they've come back to show that they all have good hearts underneath. Yamada may very well have become the nicest (or at least most well-intentioned) of the main cast as long as he doesn't get carried away in the heat of the moment.
Nene never really faces any punishment for hypnotizing several people into being her obedient love slaves. Most likely because she never demanded too much from them and, as herself discovered when Yamada accidentally uses her own power on her, life is a lot more interesting for people in love.
Ushio doesn't really face much punishment for framing Yamada as the sole perpetrator of the street fight in their backstory. He refuses to apologize for it as well. Although the reasons as to why he did it are implied to be more complicated than he lets on.
Leaning on the Fourth Wall: In chapter 96, when Yamada and Shiraishi go into a sappy, romantic mode and kiss each other again and again, Kurosaki suddenly appears and tells them this isn't a girls' manga where they can "play kissy-face". He just about manages to stay within the fourth wall because it isn't made clear if he knows that they are characters in a Shōnen manga instead, or if he thinks that their world is reality.
Legacy Character: According to Noa, the Witch powers are this. There is always a person who will have one of the Witch powers. If one Witch leaves the school, the powers will be passed onto another person. Noa herself got the power because the president ordered Tamaki to steal the power from her predecessor at the start of the year before the story begin. Also when Yamada wished for the Witch powers to go away only transferred to somebody else.
Lemony Narrator: The margin notes look informative at first glance, but they are fond of dishing out superfluous information. And making fun of Yamada.
Loss of Identity: Rika Saionji, it is revealed, lacks any real personal memories out of her duties serving the Senior Council President.
Yamada tries again in chapter 90 after Shiraishi recovers her memories. This time, They Do. For additional Awww value, she confirms that the reason why she rejected him before was because at the time she knew she was in love with someone even she couldn't remember who that person was.
Love Triangle: Yamazaki, Lenora, and Rika once the memories come back. Miyamura is disturbed.
Loving a Shadow: Meiko falls in love with Shiraishi in Yamada's body. Yamada has to explain the Witches to her to show that the person she has feelings for doesn't really exist.
Magic Kiss: How the Witches are able to use their powers.
Man, I Feel Like a Woman : Averted with Yamada, played somewhat straight with Miyamura. Also, unlike most examples of the trope, it's usually played straight when a girl is in a boy's body for the first time - it's a Running Gag that the girl looks at the boy's (usually Yamada's) junk and comments it in some way.
Yamada's given name means Dragon. Miyamura's given name has the kanji of Tiger. Dragon and Tiger. The Hero and The Lancer?
Inverted in case of Miyabi however. Miyabi means graceful but she's Tom Boy to Urara's girly girl.
Takigawa means Waterfall River. Noa has blue hair and blue eyes. Her power to see the past is like water, an irreversible flow. The name Noa is homophone with Noah.
The pinyin used in Rika's name means flower of truth.
Muggle Best Friend: Miyamura and Itou (and later Tsubaki) have no powers, regardless the club members grow very close.
My Significance Sense Is Tingling: More like genuine female intuition than a supernatural power, but in chapter 90 Nene was able to perceive the moment when Yamada and Shiraishi hooked up.
Necessary Evil: Since she started having feelings about Yamada, Shiraishi has held this view about Yamada kissing people. Since he is immune to the powers, it logically makes sense but she hates it. Especially after she became his girlfriend.
After Shiraishi was Brought Down to Normal but other Witches were revealed and Yamada had to seek them out again, he was also bothered about kissing the Witches since he'd place her under a spell if they kissed, but he figured that they'll just have to kiss twice to cancel it out.
Nice Job Breaking It, Hero: Yamada thought that the witches' powers will be gone for good. However, Yamazaki informs them that the powers themselves cannot be erased and consequently new seven witches will be selected.
Nice to the Waiter: The reason Miyamura made Arisugawa and Kurosaki the vice-presidents of the student council - even though he considered them incompetent - was that they didn't treat Yamada, the secretary (and the school's most unpopular student to boot), any different than they treated Miyamura and the other interviewers. In fact, this was one of the main reasons Yamada was appointed secretary - to see which students who didn't treat him unfairly, in order to make sure that the new student council members wouldn't be impartial.
No Ontological Inertia: Yamada hoped this would be the case when he wished for all the Witch Powers to vanish. And he was right as the memories of the ones affected by the seventh witch were returned.
No Sell: Witches' powers don't work on Yamada. However if a Witch kisses him, the power he just copied from them will instead be used on them.
Not Brainwashed: Played with. Yamada's old friend Ushio Igarashi is under the influence of Nene's Witch power, but he knows that he's under her power and accepts it.
Not Cheating Unless You Get Caught: Yamada sometimes switches with Shiraishi so she can do his tests and homework. He uses the telepathy power in order for him, Meiko, and her friends to finish their schoolwork early in summer school.
Nothing Is the Same Anymore: After over eighty chapters, major changes to the status quo arise after all seven witches are gathered for a ritual in the same place:Yamada wishes the Witch powers would go away, but this leads to the appearance of brand new ones in different people. The subplots about the antagonistic Student Council end with Yamada and friends getting control of the Council, with Miyamura as the new President and some new blood. Yamada and Shiraishi go steady.
Yamada is kind of dense about the matter, as his focus is only on Shiraishi, he doesn't realize if other girls are infatuated with him.
Nene is also oblivious to Tamaki's crush on her.
Only Sane Man: Yamada himself. Except for a few of his more Hot-Blooded moments, he actually seems to be the character with the most common sense and the most Meta Guy reactions, even if he isn't the smartest person out there.
Only Six Faces: There may be subtle differences here and there, like some characters have slightly bigger eyes or rounder heads, but in general you would have a very hard time differentiating most characters' faces if their signature hairstyles were switched around. This goes for the guys as well as the girls.
This adds some odd subtext to the revelation that Nancy is someone from Yamada's past, though he doesn't remember her - due to the art style, she looks exactly like Shiraishi when she lets her hair down.
All the students started freaking out immediately when they noticed Yamada was studying seriously.
Miyamura after his memories are wiped of Yamada being his friend, sees his now Hair-Trigger Temper sister asks Yamada in, doesn't object when Nene and Tamaki barge in, and hears his sister laugh for the first time in a long time. He finds it disturbing but enough of a reason to trust Yamada.
Opposites Attract: Yamada and Urara are as opposite as they can get as one is a Book Dumb emotion-driven fighter and the other is a stoic and brilliant student, but they both love each other.
Panty Shot: These tend to happen when Yamada is in a female body and pulls off a kick. Kimishima does one when she flips Yamada. The narration helpfully advises girls not to flip people while wearing skirts to avoid this. Saionji willingly does the other witches and Tamaki during the time stop portion of the ceremony.
Perception Filter: The power of Asuka Mikoto until Tamaki took it from her, which makes anyone that gets kissed be incapable of seeing that person. This enable her to swap body with Shiraishi and kidnap her per president's command.
Plot Hole: In the Sarushima's arc, it is established that the users of the future-sight power see their own future, but from the point of view of the person they kissed. Yamada manages to get a vision of the fire from Itou, even though it is stated in the very same chapter that it is pointless to kiss Miyamura and Itou because they weren't present at the fire. A bit later, it is revealed that Itou did see the fire from the clubroom window, but in Yamada's vision she is outside with him which doesn't happen until the future is changed much later (and then changed again before the fire can actually happen), so how he got that vision is anyone's guess.
Leona was able to stay one year out of school and not be bothered when Sarushima had to come back after several months or be excluded. The discrepancy was never explained.
Power Copying: What Yamada's power turns out to be. Effectively this makes him the only person who can use their powers on a Witch. All the other rules of powers still apply.
The Charm victims will end up being loving stalkers to the witch.
The body switch witch must switch when kissing someone, regardless of personal desires.
The two Seers must see flashes of either the future or past when they kiss.
The telepathy witch cannot stop thoughts from coming in or going out.
Power Parasite: The power of Tamaki, which steals the power of any Witch he kisses. It lasts until another girl is kissed, then the power is replaced and returns to the one the power belonged to. Leona suggested Tamaki to return his current power to Asuka and take away Rika's power.
Powers as Programs: Magic is apparently very easily copied, but on the other hand there doesn't appear to be any way of storing it. Unfortunately for Yamada he doesn't think this through and ends up overwriting the love power, leaving him unable to reverse the love effect on Miyamura and Miyabi until he can get to Nene and copy her power again. He is not pleased when he realises this.
Power Perversion Potential: Yamada is usually surprisingly responsible. However, this doesn't stop the other characters imagining what Yamada could do with the power, nor does it stop Itou and Miyamura from acting like complete perverts when under certain powers. It's safe to say that Yoshikawa, as the author, has considered the implications of the powers.
And now there are new powers the first of which is Mind Control.
Put on a Bus: Ushio has been evicted quite quickly and unceremoniously once Nene stopped running for presidency. She's now paired with Tamaki and considering their new status as clerk and treasurer of the council, it isn't going to end soon. Their much better chemistry also helps.
Commuting on a Bus: He reappeared once later on. And he caught the same dead eyes than Asuka when she was impersonating Shiraishi on his way in. Add a good dash of Green-Eyed Monster and it's likely he's going to return as an antagonist, even if Yamada didn't think anything of it.
Red Herring: Before all seven witches were accounted for, other semi-prominent female characters could be considered this - like Karen Kimishima, the archery team captain who appears occasionally.
Since four of the five original student council members turn out to be very important down the line despite that they may seem insignificant at first, you'd be forgiven if you thought that the fifth member, Inose (the girl with the pigtails and the hoodie), would be equally important. She even has more lines than the other members in their introductory chapter. But no, she never plays any role and hasn't been seen for such a long time that she may have left the series for good. She was probably just there to act as the normal student among two witches, a ruthless manipulator and a revengeful guy who wants to hunt down the seventh witch.
Revenge: Miyamura's a transfer student who went to Suzaku to hunt down the Seventh Witch who messed with his sister.
Reset Button: Rika, The Seventh Witch hits it by deleting everyone's memories of Yamada from Chapter 1 until now, reversing the Witches' character development and resulting in them blatantly misusing their powers again.
Leona, Miyamura's sister, realizes Tamaki just doesn't strip the power from a witch, he could give it back to a witch or new person.
Leona also reveals not only was she in the original Supernatural Studies Club, Yamazaki was in it too and his original goal to be Student Council President was to keep the club alive. And then Rika joined, and out of jealousy, set Yamazaki up to erase his memories so she would have him.
Miyamura learns and tells Yamada the new telepath witch and command witch had their powers long before Yamada erased the original witches' powers. As they don't know for sure how many witches there really are, they decide to just stop looking for them..
Sacred First Kiss: Interestingly averted. Both Shiraishi and Yamada say that the event that starts off the manga was their first kiss for both of them... But perhaps inevitably most characters in the manga take a more flexible view to kissing. As Miyamura points out, it's a small price to pay for being able to use Witch powers.
Played straight in Chapter 65. Shiraishi clearly treasured the fact that she was Yamada's first kiss. She wanted to stay close to him because she didn't want to risk handing that position to anybody else after he was supposed to lose his memories about it.
Screw Destiny: This is basically Yamada's aim at one point. It's possible to change Saurshima's visions by using the power of another Witch. They attempt to use Shiraishi's to change the future where the old school building is burning down.
Seers: The Witch Maria Sarushima can see the future. Unfortunately her power only allows her to see what's destined to come to pass, unless another Witch's power is used.
The Seven Mysteries: Suzaku High has their own set, and one of them is the mystery of the Witches.
Shameless Fanservice Girl: Shiraishi doesn't really have any problems with Yamada seeing her naked when he is in her body - she has even directly asked him to take a bath for her. However, going by the general inexperience she claims to have when it comes to relationships and boys (not to mention an early chapter when she displays a rather childish curiosity around the "weird thing" Yamada and Miyamura have between their legs), she may be an Innocent Fanservice Girl instead.
Shout-Out: Yamada's new partners in the Light Music Club, Sid and Nancy (who's the seventh witch), are an obvious one to Sid Vicious and Nancy Spungen. Probably an intentional In-Universe example considering that at least "Nancy" is just a nickname.
Jin Kurosaki, one of the new Vice Presidents, is called an "Assassin" by Yamada in reference to his hoodie and demeanor.
When Yamada takes on the guise of the Masked DK as part of working off the 50,000 yen fee to kiss Aiko Chikushi a witch who inherited Sarushima's power and uses it both to make money and fight crime as the Masked JK his speech is very close to the one said by Kamen Rider Stronger.
Ship Tease: Most of the time Shiraishi smiles, it's when she's around Yamada.
Shiraishi refuses to kiss Miyamura, but has no problem kissing Yamada (and Itou). But it should be noted that she doesn't have any problem with him kissing other people.
Shiraishi also seems irked that Yamada chose Itou instead of her during a school investigation.
A lot in Chapter 65. Shiraishi was resolute to sticking close to Yamada despite the danger, because she was determined to kiss him right after he lost his memory because she wanted to be his first kiss again. She was determined that nobody would "swipe her spot."
Sixth Ranger: The series quickly settles on the Supernatural Studies Club having four members. Quite a few chapters later, would-be accidental arsonist Tsubaki joins them after a subplot where they prevent the fire from happening.
Sickeningly Sweethearts: The whole Supernatural Club gets this vibe from Yamada and Takigawa Noa after the latter decides to stick a bit too close to him for a while. Mind you, Yamada constantly complains to her about it and he never once flirted back (knowingly, that's it), but it's just that his friends can tell he's being a lot nicer than they know he could be. Shiraishi correctly deduced that Yamada became very sympathetic of Noa after her power let him see a traumatic event from her past.
Skinship Grope: Poor Shiraishi cannot bathe with other girls without having them fondle her boobs... Except that Shiraishi herself has never been seen bathing - all the times, it has been Yamada in her body, which just made it even more uncomfortable.
Smarter Than You Look: Yamada, while not as brilliant as Shiraishi or Miyamura, can be very astute and keen on how to get close to some people. He is the only one noticing that Tsubasa Konno's power doesn't exactly match up with any of the old ones.
Sorting Algorithm of Evil: None of the witches are actually evil, but each new witch causes a new problem that takes more effort and more chapters to solve than it took with the previous witch. Shiraishi's arc and problem was solved in one chapter. Odagiri's arc and problem in about five chapters. Otsuka's in about five chapters, too. Sarushima's in seven chapters. Noa's in about 10 chapters. Rika's in more than 20 chapters. The exception is Asuka and Tamaki whose arc is relatively short as the hunt for the seventh witch begins soon after.
Spanner in the Works: Yamada has played this a few times by being immune to the Witch's powers. He reversed Nene's love kiss on her without knowing it would affect her, and it prompted character development in her. With his quest to undo the massive erasing of memories of the student population because he learned the seventh Witch's name. Then by helping Nene get her memories back, and the discovery the seventh Witch's power only works once, the Student Council President will put all of his attention on Yamada.
Speak of the Devil: Anyone who finds out the Seventh Witch's name (with the exception of the President) will find themselves being forgotten by everyone else. Happens to Yamada and Tamaki.
Spell My Name with an S: Ryu(u) and Ito(u) in the scanlations and the official Crunchyroll translation. Also, the "7-nin" in the title is alternately rendered in full Japanese as "nananin" in the series logo.
Staircase Tumble: In the very first chapter, which results in Shiraishi and Yamada switching bodies. Happens later on during Sarushima's arc, but thanks to it Yamada figured out other Witch powers can change the future.
Stepford Smiler: Several of the characters in the story are actually pretty broken inside, despite their outward appearance. Prominent examples are Noa and Miyamura.
The Stoic: Shiraishi's facial expression rarely changes. Even when she body swaps for the first time, she isn't alarmed about it at all.
Not So Stoic: Tamaki first appears as a male Shiraishi, with the same aloof personality and love for study books. But once he opens up to Yamada, he reveals a much goofier personality. Turns out he was aloof only because he was alone. And those books he's always seen with? They actually hide erotic light novels.
Straight Gay: New guy Kurosaki may look like Yamada 2.0 at first glance but he's hinted to have a crush on Miyamura, and applied for the Student Council to be close to him. He's also unfazed by the other new Council member, the generously endowed, (deliberately) moe Arisugawa.
The Tease: Noa to Yamada. She dials this up when she starts to fall for him.
Telepathy: The power of Meiko Otsuka who creates a Psychic Link similar to a cell phone call and requires one to picture that person in their head to send messages to them.
Too Dumb to Fool: Yamada gets this sometimes. Whenever somebody has a "wait a minute..." moment, it's usually Yamada.
Weak, but Skilled: Lampshaded. Yamada has shown to be a very good fighter in Shiraishi's and Itou's bodies even though they are smaller, weaker and more inexperienced than him. On the other hand, Itou loses miserably when she tries to fight in Yamada's more muscular and powerful body. Yamada points out that physical strength is not the factor that makes a good fighter - skills and spirit are.
Chapter 60 & 61. The Seventh Witch has been at the school for over eight years - and no, she's not a teacher.
Chapter 66: The Seventh Witch has made her appearance, but she didn't erase Yamada's memory of Witches... she erased his friends' memories of him.
Chapter 75: Saionji attempts to use her memory-wiping power again... but she discovers It Only Works Once on witches. Yamada now gets the attention of the Student Council President.
What Happened to the Mouse?: Shiraishi's trio of friends hasn't been seen since chapter 20. She may have stopped hanging out with them because they only knew and admired her as the girl who stopped the peepers (which was really Yamada), while the Supernatural Studies Club members know and respect Shiraishi's actual personality... but then again, she did seem to enjoy their company as she stayed awake all night to talk with them on the field trip. It's not known for sure why they stopped appearing.
Wistful Amnesia: As Takigawa Noa tells Yamada after recovering her memories in chapter 78, to put it mildly.
What… took you so long? There's been this… big, black hole in my heart. I was so confused. I couldn't understand why I would suddenly feel that way.
And given Shiraishi's tears after Yamada kissed Nene she feels this too.
Later revealed President Yamazaki had his memories erased by Rika so he would forget about Leona. When they meet again a year later, despite not knowing who she is, he finds himself crying.
You Are Not Alone: Yamada tells Rika Saionji this. She confesses that when her power activated, people ignored her. She was truly invisible to anyone and everyone, save the Student Council President. He could speak with her, could be friends with her. It was the foundation of her trust for him. But when Yamada shakes that, he further counters Nene, Tamaki, and he now know about her, can be friends with her. She doesn't have to rely on the President to no longer be alone.
You Gotta Have Blue Hair: Based on the color pages and the animated promo — Yamada: dark blue, Itou: dark red/maroon, Miyamura: silver, Tsubaki: green, Nene: purple, Meiko: green, Noa: light blue, Maria: light pink)
In contrast, Shiraishi is blonde as is Rika Saionji.
