Ayakashi Triangle (あやかしトライアングル) is a manga by Kentaro Yabuki that began running in Weekly Shonen Jump in June 2020.

Matsuri Kazamaki and Suzu Kanade are a teenage boy and girl who grew up close together because of their shared ability to see ayakashi, spirits that are invisible to most people. Suzu is an “ayakashi medium” whose spiritual power attracts ayakashi for good and ill. Learning this years ago inspired Matsuri to follow his family tradition and become an exorcist ninja who could protect her and others from dangerous ayakashi.

The day before the two were to start high school, Shirogane, the King of Ayakashi, reveals Suzu’s nature to her and attempts to eat her to take her power for his own. Matsuri is able to seal away his power before that happens, but not before Shirogane casts a spell that turns Matsuri female.

With no way to reverse the spell, Matsuri is forced to live publicly as a girl for the foreseeable future. Together, he and Suzu try to find some way to get the heavily-weakened Shirogane to reverse the transformation, all the while dealing with other ayakashi and Suzu’s growing power.

Ayakashi Triangle marks Yabuki’s return to Weekly Shonen Jump after the original run of To Love-Ru ended in 2009, and the first time he has written and drawn a series since Black Cat wrapped up in 2004. It is based on Reo × Leo (れお×レオ), a six-page oneshot by the same author, which was published in Jump as part of "J Romcom Festival!" for Valentine’s Day 2019. Chapters are officially released in English the same day they are published in Japan, on Manga Plus (website and app) and Viz Media’s website (though not the Shonen Jump app). Manga Plus also has simultaneous release of chapters in Spanish.

Tropes:

  • 2D Visuals, 3D Effects: Matsuri’s pinwheel is drawn using a 3D model, which is why its complicated design always looks exactly the same. For informal sketches, the artist hand-draws a flat, simplified version.
  • Adjective Noun Fred: A panel where Suzu taste-tests a donut has her refer to herself as Dessert Detective Suzu, which is accompanied by a fake logo that spells her name out with pastries.
    Shirogane: You already have plenty of titles. No need to add any nonsensical ones.
  • Alien Fair Folk: One ayakashi possessed a cymbal and flew around near a road, causing people to report UFOs. When Lu investigates the area, she runs into Shirogane, who had shapeshifted into Matsuri's male form. She had only seen that form in her dream, so she assumes "Shiromatsu" was a psychic alien and his ninja gear was a spacesuit. Shirogane decides to go along with it, and when he leaves her, the cymbal ayakashi passes overhead, convincing Lu he'd flown off to space.
  • All Women Are Doms, All Men Are Subs: In an unusual example, Matsuri (female-bodied, male-identifying) often acts sexually submissive to Reo and Suzu (female), but is very upfront and unknowingly sexually-intimidating to Soga (male). In all cases, the "more female" one is more dominant.
  • Almost Kiss:
    • As Matsuri grabs Suzu’s protectively in Chapter 2, their faces get within inches of an Accidental Kiss. Matsuri didn’t notice because he was looking away at Suzu’s attacker, but Suzu was looking straight at Matsuri, her thoughts showing a mix of surprise and excitement.
    • An ayakashi in a haunted houses ends up making Suzu and Matsuri reenact the lives of the couple who used to lived there, which they don't really resist even as it's about to make them kiss. They're stopped, and freed from its control, by Suzu's inner ayakashi medium, who's displeased they would accept such "false happiness".
  • Alone with the Psycho: Sosuke is able to get Suzu alone in a secluded area by approaching her when Matsuri was otherwise occupied, getting Lu and Yayo to think he was interested in Suzu romantically, and informing her of an ayakashi injured by the road. Once Suzu uses her powers, Sosuke devours the ayakashi that she healed, grabs her, and disappears.
  • Always in Class One: Suzu, Matsuri, Yayo, and Lu are in Hokusai High School class 1-A.
  • Ambiguously Absent Parent: Until the end of the fifth volume, Matsuri is only shown living with his grandfather, and the single reference to his parents was Muga thinking he looks like his mother. Then his mother shows up, and it’s revealed she moved for work eight years ago. His father was already “not around” by that point, and apparently hasn’t been since.
  • Anatomy of the Soul: The series loosely mixes together the concept of hun and po with qi/ki to get kon/hun/spiritual energy and haku/po/life energy. Humans possess both, but it seems other sapient lifeforms can possess just one or the other. Ayakashi only have haku, to the point they’re entirely made of it. A piece of Matsuri's spirit was able to act independently when sent into Lu's mind (with an appearance representing his self-image rather than his current state), though he seemingly couldn’t talk.
  • Anchored Ship: While conversing with Yayo in chapter 7, Matsuri states people shouldn’t even kiss before marriage, and if a man can’t get married, he’ll just have to hide his feelings. Considering same sex marriage is not legal in Japan, it implies that Matsuri doesn’t want to pursue a relationship with Suzu until he changes back to being male, even if she’s attracted to him anyway.
  • And Here He Comes Now: Seconds after Shirogane describes Garaku taking after his creator by liking cats, Garaku pops up in the (second floor) window, celebrating that he finally found Shirogane.
  • Arc Welding: Several minor ayakashi in the first volume have human faces and articles of clothing. The second volume introduces ikon, a type of amorphous ayakashi born from negative human emotions which are becoming strangely prevalent in Omiko City. It’s then revealed in volume three that ikon gradually mutate to become more human-like, first to the aforementioned human-faced monsters, then to be flat-out able to pass for human.
  • Aren't You Going to Ravish Me?: One mission required Matsuri to get close to Suzu in her sleep. When the latter is woken up in front of Matsuri, she assumes he came to have sex. She pretends to still be asleep, hoping the very-confused Matsuri will continue whatever she thinks he came to do.
  • Art Imitates Art:
  • Ate It All: Suzu tries to make food good enough to tame Shirogane, but her taste-testing repeatedly leads to her eating it all first.
  • Barbie Doll Anatomy:
    • Zig-zagged in the second chapter when Matsuri examines himself in the mirror: The full body view of his breast has blank space where his nipples would be, the closeup appears to have some areola around his fingers, and his reflection has a nipple visible as a tiny spec.
    • In most cases, his nipples have very clear outlines in many shots, but no shading.
    • In a remarkable aversion, a Panty Shot of Matsuri in the fifth chapter has very blatant camel-toe and bits of female genitals poking out the side of his fundoshi.
    • Oddly enough, male characters are drawn with nipples in the rare cases they’re seen shirtless, a detail the artist usually left out in his earlier work.
  • Back-to-Back Badasses: Suzu and Matsuri stand back-to-back and arm-to-arm as they use the former’s exploding paper and the latter’s wind for a Combination Attack to destroy the legs of Rochka’s Snowlem.
  • Bathos: An entire chapter is spent over Matsuri struggling to get by without his fundoshi. His angst and determination to do whatever it takes to get stronger is played seriously, despite revolving entirely around his underwear.
  • Bathroom Brawl: Rochka confronts and threatens Suzu while the latter is taking a bath. This was less because she was vulnerable than because Ungaikyo’s powers let Rochka come in through the mirror. Matsuri then comes out of hiding, accidentally pulls Rochka into the tub, and the hot water sends the snow ayakashi running off in pain.
  • Battle Discretion Shot: Matsuri begins one chapter half-naked and facing down a charging ayakashi. After one panel of Sword Sparks, the next is him showing off his malfunctioning Transformation Trinket to Soga at school.
  • Beach Episode: Though taking place in a mountain creek rather than a beach, the mission to defeat the Hiderigami has Matsuri’s group change into swimwear and play in the water in order to draw out the wrathful ayakashi they came to fight.
  • Beat Them at Their Own Game: Reo, whose clan rely on a very keen sense of smell, skulks around Hokusai High School and ends up being sniffed out by Suzu’s origami dog.
    Reo: A dog's sense of smell, huh? It's truly embarrassing for a Korogi to be found out by scent! And I was careful about which way the wind was blowing.
  • Big Fancy House: The Kazamaki clan have a large, traditional Japanese house. However, it’s so “traditional”, Matoi and Rochka both consider it run down and antiquated.
  • Big "WHAT?!":
    • Chapter 3 ends with Shirogane yelling “What?!” in response to Matsuri’s plans to make Shirogane his “pet”.
    • Chapter 7 ends with the same character having the same reaction to (a duplicate of) Suzu kissing Matsuri.
    • Shirogane, this time joined by Suzu and Matsuri, again says (or perhaps just thinks) “What?!” at the end of Chapter 31 when Garaku says he loved Suzu’s past life.
  • Birth/Death Juxtaposition: Garaku was born in adolescent form from an ink brush the instant the brush’s owner died right besides it.
  • Bishie Sparkle: Reo is surrounded by sparkles after she transfers to Hokusai and the males students look at her.
  • Bittersweet Ending: The Jinyo arc ends with Sosuke and his army of iyo defeated, Shirogane firmly on the side of good, and Matsuri given a few hours in his male form, during which he bonds with Suzu and realizes he’s in love with her. However, Shirogane’s power is gone for good, Suzu has to fill his place as King of Ayakashi, Matsuri has no clear means to become male again, and him being female still tremendously complicates any romance with Suzu.
  • Black Speech: The chant Matsuri performs to exorcise an ikon is written in indecipherable faux-hiragana scribbles.
  • Blood Magic: To use the god-sealing scroll, Matsuri drew a pentagram on it with his blood.
  • Blindfolded Vision: Matsuri is blindfolded when taken to a hidden ayakashi village, but has no problem walking unassisted, even on terrain that causes Suzu to trip (and pants Matsuri) with her eyes wide open.
  • Boxing Lessons for Superman: Garaku has Suzu fold paper cranes to control her haku. Not only can she bring them to life with her power when they’re done, the folding itself helps her focus.
    Garaku: You can focus your mind as you fold, and you’ll be able to tell immediately if you fail.
  • Broken Masquerade: Most of the cast have known of the existence of ayakashi for years or are completely ignorant of it, but the end of volume six has Yayo start to see them thanks to being possessed by one.
  • Bust-Contrast Duo: Matsuri’s female form is quite busty, contrasting Suzu’s far more modest chest. Inverting the usual personalities, Suzu is gentle and motherly, while Matsuri is antisocial and over-serious.
  • The Cavalry Arrives Late: A few minutes after Matsuri’s fight with Sosuke, Soga finishes off all of Sosuke’s iyo and arrives to backup his teammate.
  • Cellphones Are Useless:
    • A major part of the first chapter is Matsuri having to guess where Suzu is to save her from Shirogane, even though both are later shown with cell phones. It turns out the two had grown so distant, they never exchanged numbers; Matsuri’s contact list was just himself and his grandpa, and Suzu was surprised Matsuri even had a cell phone.
    • When Sosuke kidnaps Suzu, he deliberately leaves her cellphone behind so she can’t call for help or be tracked with it.
    • Despite being a notable Camera Fiend, Lu never even considers taking a picture with her phone when she encounters someone she believes is an alien, leaving her with no evidence of the encounter.
  • Chainmail Bikini:
    • Parodied; when Suzu asks if Reo has any cute ninja gear to try on, Reo puts her in the absurdly revealing “Sexy Gear”. It has a Giant Waist Ribbon for a partial bra, a micro thong that doesn’t even cover her whole crotch, and absolutely nothing inbetween. Neither Suzu nor Matsuri can understand why anyone would ever fight in it.
      Reo: An ayakashi would go down so easily with this seduction trap!
      Matsuri: Why would you seduce an ayakashi?!
    • Reo once modified her group’s exorcist gear into swimsuits: Soga’s became swim trunks, leaving his chest completely bare. Her and Matsuri’s become incredibly skimpy bikinis. Suzu then alters her ayakashi medium outfit into a less-revealing swimsuit. In all cases, their gear continues to protect them from heat despite covering much less of their bodies.
  • Changed My Mind, Kid: Seeing Soga dash off to hunt down Shirogane, Matsuri initially stops and says he’s glad someone will get rid of him for threatening Suzu. However, remembering Suzu’s determination to keep Shirogane alive, Matsuri is next seen riding a detached sign to save Shirogane at the last second.
  • Clarke's Third Law: Lu notes that aliens visiting Earth must have abilities humanly indistinguishable from magic. However, this line of thinking causes her to mistake actual magic as being caused by aliens.
  • Clothing Damage:
    • Matsuri once suffered a rather literal Wardrobe Malfunction when using his choker, leaving his ninja suit only partially formed. Luckily, his fundoshi (the one article of clothing he wears with both outfits) and sword were in-tact.
    • Matsuri gets engulfed by Chirizuka Kaiou’s corrosive wind, and though its effects are reversed before it can hurt him, most of his battlesuit instantly disintegrates and stays gone. Oddly, his regular clothes were undamaged when he changed back into them, but he still needed to repair the suit.
  • Compliment Backfire: Reo has an odd way to express approval for Suzu’s ayakashi medium gear.
    Reo: The tackiness is quite lovely!
    Suzu: That’s not a compliment!
  • Curse: Shirogane's spell turns Matsuri's female and leaves a mark on his abdomen. Rather than making Matsuri inherently female, the spell is persistently maintaining his female form through the mark. Shirogane claims he could remove it, but only if his power is restored, and if he perishes it will become completely irreversible.
  • Childhood Friends:
    • Suzu and Matsuri have been friends since early childhood, both because they could see ayakashi together and grew up close by. There are signs of a budding Childhood Friend Romance, more so on Suzu's sides, and their relationship has been rough since Matsuri became a exorcist ninja.
    • Reo and Soga have known each other since early childhood because their fathers are close work friends. They've never really been on "friendly" terms though, as Soga was constantly running in fear of Reo's inventions she wanted to test on him.
  • Claimed by the Supernatural: Matsuri's sex transformation left a mark centered on his navel consisting of overlapping male and female symbols with a spiral in the center. Curiously, the symbol shown when the spell was cast was rotated 180 degrees, making the male symbol point down and the female point up. Like the ayakashi who left it, the mark is Invisible to Normals. When the mark is drained of haku, temporarily restoring Matsuri’s original form, the mark fades heavily. It’s solid again the instant it reactivates.
  • Commonality Connection:
    • When she was very young, Suzu loved playing with ayakashi, but was driven away from other humans because they thought she was making them up. Once Matsuri met her and made it clear he saw them as well, they quickly became inseparable.
    • Lu and Matsuri bond over similar tastes in (invokedgenerally male-oriented) manga.
  • Congruent Memory: Matsuri has worn fundoshi with all his outfits ever since he decided to become an exorcist ninja. Consequently, changing to a different type of underwear initially negates his superhuman agility, leaving him too clumsy to clear a vault in gym class.
    What's wrong with me? I can't do anything right. My lower body feels weak.
  • Conversational Troping: Matsuri asks Soga how his hopes of a Childhood Friend Romance stacks up to a theoretical Reincarnation Romance. Soga assesses that between the two tropes, Matsuri is at a disadvantage, but not an insurmountable one. Matsuri is consoled, but also wonders how Soga knows the word "trope".
  • Corner of Woe: Soga sulks with his hand on the wall when thinking about how easily Garaku subdued him even while holding back enough not to hurt him. Matsuri cheers him up (and makes his heart skip a beat) by encouraging them to both get stronger together.
  • Costume-Test Montage: During a shopping trip, Matsuri tries out four different girl outfits: a boyish look with shorts, a sundress, an Elegant Gothic Lolita getup, and Magical Kyouko cosplay. Each gets a Reaction Shot from Reo, Suzu, and Shirogane, the first always being excited, while the other two are put off by the increasingly absurd outfits Reo picked ("What's up with the selection in this store?") and Matsuri happily going along thanks to Reo’s incense.
  • Covert Group with Mundane Front: The Korogi clan run a tool shop for exorcist ninja that doubles as a toy store. Alongside mundane merchandise are things like swords and scrolls that have been rendered Invisible to Normals.
  • Creature-Hunter Organization: Matsuri and others work under the Exorcist Ninja Association, a secret organization founded by the government of Japan hundreds of years ago. They provide local agents across the country with special knowledge, training, and equipment to protect the public from dangerous ayakashi.
  • Cross-Referenced Titles: Soga’s introductory chapter is titled “The Lightning-Fast Exorcist Ninja”. The chapter that introduces his father is titled “The Lightning-Fast Father”.
  • Crossover Cosmology: Despite always being referred to by a Japanese word, ayakashi exist all over the world. Since many are tulpa shaped by human belief, they correspond to their native mythology. One chapter sees Snegurocha, the snow maiden of Russian folklore, coming to Japan to claim the title of King of the Ayakashi.
    Garaku: In this global era, it's not surprising to see foreign ayakashi around.
  • Crossover Punchline: In chapter 8, Shirogane tries to track down an ayakashi by smell, but ends up finding a cartoon standee of Kyouko from Black Cat and To Love-Ru.
  • Crush Filter: As Soga is conflicted on treating Matsuri as a guy but being distracted by his looks, we get a closeup where Matsuri is drawn with doe eyes, full lips, Bishie Sparkles in the background, and his cleavage prominently visible.
  • A Date with Rosie Palms: In chapter 7, Suzu curls up on her bed while thinking if kissing Matsuri could make him male again. The next page shows her asleep, but her hand between her legs, the fingers pointed at her crotch, and the closeup of her eyes suggests she may have pleasured herself beforehand.
  • Declaration of Protection: After coming to love Suzu, Soga decides to let her know he plans to join Matsuri in protecting her. Unfortunately, he messes up his words, and says Matsuri is the one he wants to protect.
  • Did You Just Flip Off Cthulhu?: As Shirogane boasts his status as the king of the ayakashi, Suzu expresses amazement while continuing to give him an unwelcome belly-rub and coos about how cute he is.
  • Different for Girls:
    • Matsuri generally doesn’t even try to act feminine, but struggles with the few attempts he does make to fit in as a girl. His lack of modesty with his skirt during simple gestures like running up stairs or continuing to sit down with his legs spread out causes Suzu to repeatedly reprimand him, and he's had to be dragged out by teachers for continuing to accidentally use the men's room. Matsuri’s one attempt at being feminine, as a disguise, failed immediately by being so over-the-top cutesy.
    • Another issue Matsuri doesn't understand is how people view him interacting with (what is now) the opposite sex. Everyone sees his casual interaction with Soga as romantic (completely missing his actual love for Suzu), and Matsuri's female friends pester them to get together. When the idea of Soga dating someone else comes up, it's pointed out Soga could come off as unfaithful if they keep acting as they do, leaving Matsuri utterly aghast.
  • Disapproving Look: Matsuri became part of Suzu’s group of friends to bodyguard her, and so claims he shouldn’t have to bother being friends with Yayo or Lu. After one Page-Turn Surprise to Suzu’s very bemused and shaking head, Matsuri immediately reconsiders.
  • Dogpile Of Doom: As Matsuri runs after Suzu and Sosuke, Lu and Yayo jump on top of him, (somewhat correctly) assuming he wants to keep Suzu from making a boyfriend. It doesn’t seem to slow Matsuri down much, and he’s able to shake them before reaching his destination (though not in time to help).
  • Doppelgänger: Also known as an Omokage Shadow, one appears in chapter 7 and 8.
  • Double-Meaning Title: Chapter 14, which ends with a G-Rated Sex scene where Suzu puts her haku into Matsuri’s body, is titled with the rather blatant Double Entendre “Inside Matsuri”.
  • Double Standard: Rape, Female on Female: The manga often has female characters casually grope others with little consequence, including Yayo (initially) and Reo. In one extreme case, Matsuri’s mother confirms he’d become entirely female via Crotch-Grab Sex Check (made worse by her being disguised as someone he barely knew at the time). Despite Matsuri being the most common victim (overlapping with Double Standard: Rape, Female on Male), he gets much angrier at boys who glare at or hit on girls.
  • Dragged by the Collar:
    • Although Suzu manages to persuade Matsuri to befriend Yayo and Lu, she still has to literally push him along to meet up with the pair.
    • Suzu again tries to push Matsuri and carry Shirogane into a meeting with Ponosuke and Soga. Both of them end up getting away from her.
    • Matsuri comes to Soga's class and calls for him by name, making them think Matsuri is his girlfriend, and irritating Soga so much he lifts Matsuri off the ground by the shirt and carries him into the hallway.
  • Dramedy: The manga's default tone is comedic, but even aside from perilous situations, there's a decent amount of character drama, often juxtaposed with more comedy.
  • Dropped After the Pilot: In Reo × Leo, the protagonist’s father is set up as an antagonist who changed him into a girl in the first place. Matsuri’s father in the actual series is barely ever mentioned.
  • Dynamic Entry: Matsuri flies up directly in front of Sosuke as he pursues Suzu, catching him by surprise before punching him in the face so hard he bounces along the ground.
  • Ecchi: Panty Shots and nudity are common, as are characters getting in incredibly suggestive situations.
  • Embarrassing but Empowering Outfit: An indirect example; Matoi concludes regular panties can strengthen Matsuri—not immediately, but as a means of training his spiritual powers based on embarrassment itself.
    Matoi: Since you're a boy, you prefer traditional fundoshi! But now you must start wearing panties! You'll feel resistant and experience great discomfort, but those emotions will serve to strengthen your spirit and be far more effective than any ascetic training you might do under a mighty waterfall! This is training only you can do!
  • Empathic Environment: After Matsuri is forced to kill an ayakashi Suzu thought she could save, heavy rain falls to emphasize their melancholy.
  • Elemental Rivalry: Matsuri has wind powers, while his rival and partner Soga is associated with thunder and lightning.
  • Energetic and Soft-Spoken Duo: Yayo is loud and very expressive, while Lu talks quietly and hardly emotes at all. Despite contrasting temperaments, their actions and trains of thought tend to be highly synchronized.
  • Epiphany Comeback: By his rematch with Sosuke, seeing Suzu really had become Shirogane’s close friend makes Matsuri realize he has better options than a straightforward attack. Instead, he uses an as-yet-unmastered technique to calmly wait for Sosuke to attack first and create an opening.
  • Erotic Dream: A pirate-themed omake celebrating the 1000th chapter of One Piece has (male) Matsuri leading a crew of ayakashi onto an “island” that’s actually a giant Suzu’s bare thigh. Suzu flicking them away reveals this was a dream by a panicked Matsuri, who a caption describes as "still a young man at heart".
  • Everyone Can See It: Zig-zagged concerning Suzu and Matsuri's attraction to each other. From the beginning, Seigen knows how they feel for each other, Soga suspects Matsuri's feelings enough to ask him, and Reo knows she can barely compete with Suzu as a romantic rival. Later on, Soga realizes Suzu loves Matsuri when she hugs his temporarily-restored male form, and can't believe Matsuri didn’t come to the same conclusion. On the other hand, Yayo and Lu haven't noticed their attraction at all; thinking Matsuri is a girl makes them disinclined to think of the two as a couple.
  • Exact Words:
    • Suzu introduces Matsuri to Lu and Yayo as a friend of hers from elementary school. This is technically true, but leaves out that Matsuri was already a classmate of theirs in middle school when he was still a guy.
    • Suzu asks Matsuri why he's quiet whenever Lu or Yayo are around, which he excuses as not knowing what to say to girls. Suzu asks what he does with his male friends, and Matsuri admits he's really not used to talking to much of anyone.
    • Matsuri says he carries the God-Sealing Scroll around all the time for good luck because his family are descendants of ninja. He leaves out how he himself is a ninja.
  • Exactly What I Aimed At: Matsuri throws a shuriken in Utagawa’s direction, who assumes it misses when it hits a faucet and makes water flow out. Later, Matsuri throws a spiraling ball of wind at the water, spraying it all over and dissolving Utagawa’s drawings.
  • Faceless Masses: Incidental characters are often drawn abstractly enough that they have little facial detail, sometimes even when they have dialogue.
  • Fan Disservice: The effects of Sosuke’s Vampiric Draining of Matsuri are visualized as his naked body missing the paralyzed parts. This leads to a Boobs-and-Butt Pose where Matsuri’s thigh and buttock appear torn out, and a frontal view where the same goes for his breast, abdomen, and even his crotch.
  • Fanservice Cover: Some of the title pages include very racy illustrations, often in otherwise clean chapters. For instance, the cover of chapter 29 has Matsuri holding a guitar that barely obscures his nudity.
  • Fantastic Religious Weirdness: When Yayo was possessed, she grabbed as many holy symbols as she could, from several different religions: a cross, Buddhist prayer beads and chant, and a Shinto charm. (She also threw in salt and garlic.) They had no effect whatsoever.
  • The Farmer and the Viper:
    • Suzu defends Shirogane from Matsuri's initial suspicion, figuring Matsuri was just being paranoid again. However, Shirogane was planning from the beginning to kill Suzu, and treating him nicely didn't change his mind. This is subverted long-term, when Shirogane being forced to live with Suzu gets him more attached and ultimately convinces him to abandon eating her.
    • Suzu’s later attempt to spare the Hiderigami is less successful, as he simply pretends to accept it as a way to attack her. Matsuri abruptly kills him before Suzu even realizes the Hiderigami’s trick.
  • Fastball Special: In chapter 8, Matsuri uses a blast of wind to send Shirogane at Suzu’s omokage, and while in midair he transforms into a (fake) crepe (which was meant as a distraction, but solved the problem entirely by fulfilling the omokage’s Ghostly Goals).
  • Feet-First Introduction: As Matsuri’s mother removes her school teacher disguise, the first we see of the real her is a closeup of her foot.
  • First-Episode Twist: The first chapter plays out as the beginning of a Childhood Friend Romance mixed with a supernatural action story. Near the end, Matsuri is changed from male to female for the foreseeable future, something the advertising gave little to no hint of.
  • First Law of Gender-Bending: Shirogane turned Matsuri female, and is seemingly the only one who can change him back. Shirogane has no reason to do so, as Matsuri is his enemy, and would only be able if his full power was restored—which Matsuri can't allow, because then Shirogane would kill Suzu and likely others. Matsuri himself almost makes this change permanent when confronting Shirogane outside his house; he'd gladly exorcise the ayakashi to keep Suzu safe even if it meant that he'd seal away the only individual who could reverse his transformation. Eventually, Suzu discovers she has the potential to remove ayakashi curses, but this particular one is far beyond her current capabilities. Shirogane eventually gets his powers back after becoming Suzu and Matsuri’s ally, but loses them more permanently before he can change Matsuri back—partly because Matsuri refused to release them when they had the time. Thereafter, Matsuri’s best chance for being male again requires Suzu to develop her powers enough to restore Shirogane’s, not knowing for certain if it’s even possible or how long it would take.
  • First-Name Basis:
    • Most of the cast go by their first name, as they’re either peers or supernatural beings with Only One Name.
    • After their initial meaning, Reo and Suzu go by first name, but then Suzu switches back to “Korogi” when Reo transfers to the same school. Reo complains, so Suzu calls her “Reo” again (though in Japanese she still says “Reo-senpai” instead of “Reo-chan”).
    • As they’ve known each other since childhood, Reo is initially the only other student to call Soga by his first name. Tellingly, Soga does not return the favor.
    • After a Platonic Declaration of Love, Matsuri finally starts addressing Soga by his first name, though he occasionally falls into old habits (calling him "Ninokuru" in English and "(Soga-)senpai" in Japanese).
  • Flash Step: Various ninja characters will appear or disappear in a blur. It’s generally not a combat technique, just a dramatic way to enter or exit a scene.
  • For Halloween, I Am Going as Myself: Garaku gets Matsuri to blend in with ayakashi by pretending he’s an ayakashi disguised as a human. Specifically, Garaku puts him in a kimono and fox mask that hides his human spiritual presence, so ayakashi assume Matsuri is a kitsune.
  • Forceful Kiss: In chapter 7 and 8, an ayakashi duplicate of Suzu sneaks into Matsuri's room and kisses him, acting on her guess that a True Love's Kiss could change him back into a boy. Matsuri was too surprised to resist at first, but once the kiss turned heavy, he pulled away just as the ayakashi disappeared.
  • The Force Is Strong with This One: The ability to see ayakashi is closely related to the ability to feel their energy in proximity. If an ayakashi’s energy is too weak for you to feel, you probably won’t be able to see it either. Ayakashi can also conceal their strength in various ways: Shirogane’s Sleep-Mode Size makes him seem much weaker, while a fully-formed jinyo like Sosuke is difficult to tell apart from a regular human even from sensing his energy.
  • Four-Girl Ensemble: Kachofugetsu consists of Suzu (the sweet one who is also the Team Mom), Yayo (the most energetic and openly sexual), Matsuri (who presents himself as a tomboy), and Lu (who looks and acts the most childish, though she’s not entirely innocent). Before Matsuri joined, the other three fit the The Three Faces of Eve, with Suzu, Yayo, and Lu as the Wife, Seductress, and Child, respectively.
  • Fourth-Wall Portrait: Utagawa is introduced sketching a kappa giving him some information, giving him the sketch afterward. The drawing is more realistic than the actual artstyle, which causes the kappa to tear it up.
    Kappa: It’s so realistic, it’s creepy, ‘ppa.
    Utagawa: But I paid so much attention to the textures!
  • Friend Versus Lover: Matsuri spends one chapter preemptively worried that Soga getting a girlfriend would hurt their friendship. Not because it would take up all Soga's time, but because Lu and Yayo say girls can’t be close with guys that are dating other people (though that may be because they assume Matsuri loves Soga).
    Yayo: [Soga and Reo are] definitely gonna be a couple! Then you won't be able to talk to him as freely as you've been doing!
    Matsuri: What?! Seriously? If Ninokuru gets a girlfriend, I can't talk to him anymore?!
    Yayo: Of course not. You're a girl, so you have to be considerate of a guy's girlfriend.
    Matsuri: I need to go talk to him!
  • Full-Name Basis: Soga is so impersonal, he calls even close acquaintances by their full name (just their last if he wants to be brief). Bizarrely, he also applies this to himself—not just when introducing himself, but for internal monologues.
  • Fun with Homophones: Shirogane’s spell that changed Matsuri’s sex is written “性・醒・流・転”. The punctuation indicates each kanji is a separate word, thus “Sei Sei Ru Ten” (which literally translates to “Sex Awakening Exile Alteration”; in the English version “Gender Swap Awakened”). It’s also a near homophone for “生々流転 (Seisei Ruten)”, a four-kanji idiom describing the flow of souls through a cycle of reincarnation (as Matsuri is “reborn” in an altered body and takes up a new identity).
  • Hidden Elf Village: In the mountains near Omiko City is a hidden village inhabited by ayakashi who’ve lost their place in the modern world. It seems to be in another dimension where the sky looks like a painting, accessible only by walking through seven torii in the proper order.
  • G-Rated Sex:
    • Suzu once tried to reverse Matsuri’s transformation by sending her haku into his body, which happens in an absurdly sexual manner: Both are on Suzu’s bed, Matsuri’s shirt is open, and Suzu’s hand is on the spell mark on his exposed abdomen. The dialogue and positions (Matsuri on his back, Suzu over him) are suggestive of Suzu having a role that is not only dominant, but specifically male.
      Matsuri: Something hot is flowing into me from Suzu.

      Suzu: You felt what came from me go inside of you?
      Matsuri: Yeah... Does it... make you tired or anything?
      Suzu: Not at all.
    • During a heatwave, Suzu is repeatedly left collapsed and heavily panting, begging for Matsuri to cool her off with his wind, and moaning in relief whenever he does. Matsuri is fully aware of how suggestive things are (and quite aroused because he has a sweat fetish), but Suzu obliviously throws out comments about Matsuri "doing it [to her]".
      Suzu: I think we should do it in my room. Our homework.
  • Gainaxing: A jog in gym clothes in chapter 10 makes Matsuri’s breast wildly shake up and down, out of sync, even though he's wearing a sports bra.
  • Gender Bender: Matsuri is turned female by Shirogane's spell to hinder his relationship with Suzu. The only sure way to change back is for Shirogane to undo it himself, but it's speculated Suzu could do the same if she were to fully realize her powers as as ayakashi medium.
  • Gender Bender Angst: Played with; Matsuri wants to be male again and has shown no desire to adapt to being a girl, but he's not very upset about it either, and would even accept staying as one forever if he has to. His friend Suzu has the lion's share of the ensuing angst: She blames herself for the transformation and is uncomfortable with how she's still attracted to Matsuri as a girl. Eventually, Matsuri himself starts to see staying female as worse than he first thought, especially since he assumes that means he's stuck as Suzu's "girl friend" (ironic, given the last point).
  • Gender-Bender Friendship:
    • While the two have been close friends even before Matsuri's transformation, he directly asks to be one of Suzu's girl friends in her group to make sure he can defend her from hostile ayakashi. Though she was previously skeptical about Matsuri getting closer just because he became a girl, she takes no issue with it by the time Matsuri actually asks. In a twist, Suzu is attracted to Matsuri both in male and female form, and is (at least subconsciously) using being "both girls" as an excuse to get closer to him romantically. Living so closely with Suzu directly leads to Matsuri realizing he loves her.
    • In a straighter example, Matsuri’s newfound closeness to Suzu leads him to sharing her friendship with Lu and Yayo. It turns out that, besides Suzu, they aren’t just his first female friends, but his first other friends at all.
  • Gentle Touch vs. Firm Hand: After Shirogane is made the Kazamaki family “pet”, Matsuri is very short with him, not expecting much besides to keep him from causing more trouble, while Suzu hopes she can befriend and reform Shirogane by treating him with kindness.
  • Ghosts Abhor a Vacuum: Reo is introduced sucking up an ikon into a hand-pumped tube; a solid ayakashi like Shirogane merely gets his tail stuck in the nozzle. The talismans wrapped around the cylinder are meant to keep things inside, but they’re able to break it open by force.
  • The Glomp:
    • Shortly after her introduction, Reo hugs Matsuri and pulls him to the ground. The English version even translates the sound of them hitting the floor as "glomp".
    • Matsuri gets tackle-hugged again, except by Suzu, when he turns out to have survived Sosuke’s draining his Life Energy.
  • Gratuitous English:
    • The second word of the Japanese title is the English word “triangle” transliterated into katakana, instead of the language’s own word for triangle (sankakkei).
    • When Lu notices Matsuri is like a ninja in chapter 6, her text box in the Japanese version spells out “NINJA” in all-caps English letters.
  • Guys Smash, Girls Shoot: Soga is a Close-Range Combatant who uses arm blades. By contrast, Reo uses gadgets and incense, while most of Suzu's powers make her The Minion Master in one way or another. Appropriately, Matsuri uses his sword, shuriken, and wind spells at both close and long range.
  • Hair Color Dissonance:
    • Matsuri's male form, Matoi, Suzu, Soga, and Sosuke most likely all have black hair. However, color pages show Suzu, Soga, and Sosuke's hair as dark shades of purple, blue, and green, respectively, and give Matsuri and Matoi's streaks of dark red.
    • Matsuri's female form is described as having silver hair, but it's colored with a slight pink shade.
  • Happiness in Mind Control: When forced to reenact the daily lives of a Happily Married couple by an ayakashi, Suzu and Matsuri are fully aware they're being controlled, but don’t resist much at all. They just focus on how close they feel without anyone else around. However, when an outside party frees them, they don’t take any particular issue.
  • Heat Wave: After being released, the Hiderigami causes a heat wave in Omiko City that brings temperatures over 40C / 100F even by mid-morning.
  • Heroic Second Wind: In a ridiculous example bordering on parody, Suzu passes out from overheating, then gets back up so Reo won’t be the only one to put suntan oil on Matsuri’s body.
  • Hot Springs Episode: Chapter 11 has Matsuri and Suzu visiting Lu’s Big Fancy House to exorcise an ayakashi possessing her, under the pretext of a sleepover, and Lu insists they start by using her family’s open air bath together. This puts Matsuri, who doesn’t think he should be seeing girls naked, in an awkward position when Lu and Yayo refuse to let him bathe separately. However, the actual bath is cut short when Lu’s possession causes her to pass out.
  • I Can't Feel My Legs: Sosuke’s surprise attack paralyzes Matsuri’s leg, and his inner monologue expresses the loss of feeling before collapsing.
  • I Did What I Had to Do: Matsuri kills the Hiderigami when Suzu thought he was reforming, and repeatedly says “I had to do it.”—honestly convinced he did the right thing, but worried Suzu may resent him anyway.
  • I Need to Go Iron My Dog: In chapter 2, Suzu uses her own Sweet Tooth as an excuse to follow Matsuri chasing Shirogane.
    Yayo: Suzu, where are you going?
    Suzu: Gonna see if the cafeteria sells creme brulee!
    Yayo: I doubt it.
  • I Never Said It Was Poison: After Suzu heals a small ayakashi, Sosuke says he was surprised an ayakashi medium can really do that. Suzu realizes too late that she never said she was one, and that Sosuke was just pretending to barely know what ayakashi were.
  • I Never Told You My Name:
    • When Matsuri sees Suzu’s brother Ritta for the first time in years, he calls him by name and observes his growth, even though Ritta’s never seen Matsuri as a girl before. Matsuri hastily says they met briefly before, and when Suzu calls Matsuri by name, Ritta remembers him and concludes that Matsuri was always a girl.
    • Shirogane knows Lucy and Yayo’s names from hanging around the school, but they only know him as a stray cat. When Shirogane appears before Lu in the form of boy Matsuri, he blithely refers to her by name, making her think he’s a telepathic alien.
  • I Am Not Weasel: The first time Reo sees Shirogane, she wonders if he's an "ayakashi pig". Much later, Yayo makes the same mistake.
    Shirogane: I’m a noble white cat!
  • I'm Crying, but I Don't Know Why: Seeing Garaku's painting of a tree made Suzu tear up and feel nostalgic, even though the tree was torn down over a century before she was born. She's reacting to subconscious Past-Life Memories of hanging around the tree.
  • Idiots Cannot Catch Colds: Suzu mentions she’s never gotten sick. She theorizes being an ayakashi medium gives her Ideal Illness Immunity, but it doubles as an unstated joke about her scatterbrained personality.
  • Imaginary Love Triangle:
    • There is a Love Triangle between Matsuri, Suzu, and Soga, as Soga and Matsuri both love Suzu, but Suzu ends up mistaking Soga as her rival for Matsuri's affection. She’s not totally wrong—Soga is also attracted to Matsuri—but he's unwilling to act on it, and it’s only thanks to a series of misunderstandings that Suzu is worried they’re fooling around.
    • Similarly, Lu and Yayo (who only know Matsuri as a girl) think Soga and Matsuri form a different love triangle where Reo also loves Soga. The reality is that Soga and Reo are mutually disinterested, and Reo also loves Matsuri.
    • Matsuri comes to fear Garaku as a romantic rival for Suzu's affection because Garaku knew Suzu's past life, even though there's no signs of attraction between them (not to a mention a huge age difference).
  • Incompatible Orientation: Suzu and Matsuri began the series with a heterosexual romantic tension, then Matsuri's sex is changed involuntarily. Though this hasn't actually eliminated any chance of a relationship between them, the idea it could is still brought up or assumed:
    • Shirogane made Matsuri female entirely to foil Suzu's crush on him. To Shirogane's surprise, Suzu remains attracted to Matsuri, though she's far more reluctant. Matsuri doesn't notice this though, and still assume he can't be more than Suzu's "girl friend" unless he changes back.
    • Suzu possibly develops the opposite concern—of Matsuri only becoming attracted to guys—because of his growing closeness to Soga. Although it’s also possible Suzu just fears Soga specifically as romantic competition, even if Matsuri’s transformation made him bisexual.
  • Indirect Kiss: A supernatural version: Suzu’s Enemy Without ends up sneaking into Matsuri’s room at night and forcibly kisses Matsuri. While Suzu and Matsuri were whole buildings apart, Suzu’s senses were linked with her doppelganger, so both felt as if they really were kissing. Both end up pretending like it never happened.
  • Inner Monologue Conversation: Several times, Suzu and Matsuri seem as if they’re conversing when their dialogue is only in thought balloons. Presumably they’re in sync enough to judge each other’s intent nonverbal.
  • Instant Cosplay Surprise:
    • Reo gives Suzu a "cute" ninja suit, and since it's put on via transformation, Suzu can't tell it's a Chainmail Bikini until she’s already wearing it.
    • After Matsuri accidentally gets himself into a shopping trip for girls clothes, Reo has him smell incense to give him the courage to wear any outfit without hesitation. It works so well, he ends up putting on a set of frilly lingerie and stepping out of the dressing room before he realizes he's changed underwear at all.
    • When Reo modifies the exorcist ninja’s suits for a mission, she doesn’t explain why until after they’ve been changed in a poof of smoke to swimsuits. Matsuri is briefly embarrassed by how revealing she made his.
  • Instant Costume Change:
    • Matsuri minimizes the amount of time he has to spend in the girl’s locker room by changing clothes for gym class super fast. It has the unintended bonus of denying Shirogane a chance to steal the scroll tucked into the back of Matsuri’s sports bra.
    • Exorcist ninja gear doesn’t only switch the wearer instantly into a battlesuit, they can be further modified with a portable external device while still being worn. Suzu can modify her ayakashi medium costume similarly without any kind of external tool.
  • Instantly Proven Wrong: Matsuri refuses to believe Suzu can manipulate haku to affect anything seconds before she actually makes her plush doll start moving on its own.
  • Interrupted Bath: Matsuri's Shower Scene in chapter 3 is interrupted by Shirogane, who came disguised as Suzu in an attempt to steal the god-sealing scroll.
  • Intoxication Ensues: Suzu tries putting catnip in Shirogane’s food, which he quickly gobbles down without knowing while disguised as Matsuri. He ends up mistaking Lu for a pile of dumplings and rants about her "belonging to him" before passing out.
  • Invisibility Cloak: Exorcist ninja’s battle gear renders them Invisible to Normals just like ayakashi themselves. The Kotorogi clan put their exorcist ninja tools in packaging that does the same, letting them offer their wares while pretending to simply be a toy store. Reo has her own version that's an actual cloak and even the spiritually-aware can't see her through, though they may still notice she's in proximity.
  • Invisible to Normals: Ayakashi are invisible and inaudible to humans unless they have some kind of spiritual power (even if they aren't able to use it) or the ayakashi takes deliberate efforts to make themselves visible.
  • Ironic Echo:
    • In her head, Suzu describes Matsuri as “cool” when thinking of when he rescued her from an ayakashi at school. A flashback in a later chapter shows Matsuri had the same reaction to Suzu when he saw ayakashi following her.
    • When Matsuri asserts he’ll protect Shirogane purely on Suzu’s behalf, Soga replies “Infatuated with a woman? How juvenile.” After Soga accidentally looks up Matsuri’s skirt and runs away in shame, he chastises himself with “I’m… so juvenile.”
  • It Only Works Once: The god-sealing scroll that took away most of Shirogane's power took decades to create, and can't be used twice. Since it was the only way Matsuri was able to defeat him, Shirogane would be all-but-unstoppable were his powers restored.
  • Journey to the Center of the Mind: When Lu is possessed by an ikon in chapter 11, Matsuri uses his fan to expel it from her body in her sleep. To his surprise, this involved a piece of his spirit entering her body, then showing up in her dreams (in male form) to defend Lu and get her to aid in the ritual.
  • "Just Joking" Justification: Matoi asks her child if Suzu would still side with humans if she gained her Past-Life Memories of being killed by them, pointing out how many powerful enemies that would give them. When Matsuri is offended by his mother’s attempts to sow doubt in his best friend, Matoi brushes it off as just a means to make him flustered.
  • Ki Manipulation: Powers in this setting are mostly based on two kinds of ki-like energy; kon/spiritual energy and haku/life energy. Most humans can only strengthen and manipulate their kon, which is what powers like Matsuri's ninjutsu are based on. Ayakashi powers use haku (they don’t have any kon), but they don’t seem to be able to manipulate it in the same way. Ayakashi mediums possess not only an unusually large amount of haku, but are uniquely able to control it, giving them powers that are especially effective on ayakashi and related phenomena.
  • Kick Them While They Are Down: Sosuke eating Matsuri’s haku leaves him disarmed, on his knees, and with an arm and leg unable to move. After briefly gloating, Sosuke continues to eat Matsuri’s life away, piece by piece.
  • Lady and Knight: Matsuri is an exorcist ninja sworn to protect Suzu, a very kind person whose nature as an ayakashi medium gives her a sort of authority among ayakashi—Suzu’s ability to command them is what first brought Matsuri’s admiration. Utagawa admiringly calls them “The lady knight protecting her princess.”
  • Last-Name Basis: Characters usually call Soga “Ninokuru”, as most of the named students are a year younger than him.
  • Lawyer-Friendly Cameo A cart-racing game Matsuri plays with Rochka clearly features the title character of Cheburashka and his nemesis Shapoklyak, but they’re only shown from the back.
  • "Leave Your Quest" Test: When Matsuri is struggling with his training, Reo offers him a respite in the form of a new pair of fundoshi (“advanced fundoshi” at that). Matsuri is tempted but refuses, emphasizing his need to get stronger regardless of such personal costs. Then he shows off his new girly underwear to Reo, which brings a tear to her eye. Turns out Matoi put Reo up to it to test his willpower, and she’s impressed.
  • Lesser of Two Evils: The Exorcist Ninja Association once assigned Matsuri to collect a sample of Suzu's haku that basically required him to kiss her belly button while she’s sleeping. Despite how embarrassed the idea leaves him, Reo convinces Matsuri he’s better off doing it, or else it’ll just be passed onto another exorcist ninja (like Soga).
  • Lingerie Scene:
    • Matsuri is frequently shown hanging around his house shirtless, only wearing a sports bra on top.
    • One scene deals with Matsuri changing for gym class, which shows him, Suzu, and Lu in only their underwear.
  • Literal Metaphor: In Japanese, the native words for “sex” and “gender” are the same, so a person’s gender identity is often described as the sex/gender of their "heart/spirit/soul". For Matsuri this idea is applied very literally; him still identifying as male despite his transformation is shown by his actual spirit retaining his original form when part of it enters Lu’s mind (which she sees that way even though she’d only known Matsuri to be a girl).
  • Loss of Inhibitions: When Matsuri hesitates to try on girls’ clothes during a shopping trip, Reo has him smell some incense for "the courage to take a new step forward". Matsuri then wears every ridiculous getup Reo picks out for him with maniacally enthusiasm, and switches his underwear with lingerie without noticing. He snaps out of it when he sees the latter, after stepping out in front of his friends, and is predictably embarrassed.
  • Lost in Translation:
    • In the Japanese version, Matsuri introduced himself to Yayo (still) using the very masculine pronoun ore, which caused Yayo to call him an "orekko". In the English version, nothing about his speech is specifically masculine, but Yayo still calls him a tomboy without seeing "her" do anything boyish.
    • Matoi repeatedly talks about moving in with Matsuri to take command of his “chōkyō (調教)”, which the English version translates as “training”. This loses some of the sinister subtext, as the original term specifically describes the training of an animal. The Spanish version uses “domarte (taming)”, which has the opposite problem of making it sound like she’s just training to alter his behavior, not make him stronger.
    • After incapacitating the Hiderigami, Matsuri brags of his power increase from losing his fundoshi with “I’m not a girl just for show!” Part of the joke in Japanese was that he was calling himself female using very masculine language (specifically, substituting the negating suffix “-nai” with the rougher equivalent “-nē”, and adding “ze” to the end of the sentence).
  • Loud Gulp: Matsuri gulps audibly when Garaku takes Shirogane away from their lunch with Suzu, leaving Matsuri alone with Suzu in her room.
  • Love Confessor:
    • Soga tells Matsuri that he loves Suzu before his attempt to (partially) let her know the same, reasoning Matsuri should know because they’re so close. Matsuri doesn’t think it’s any of his business, though he’s lying when he says he has no problem with it at all.
    • After Matsuri’s Love Epiphany for Suzu, he quickly lets Soga know. Soga immediately tells Matsuri he’s a more appropriate suitor, can’t believe he’s second-guessing that she feels the same, and encourages Matsuri to pursue a relationship regardless of how his body currently is.
  • Love Epiphany: When Suzu hugs Matsuri after his fight with Sosuke, which temporarily turned him male again, he’s shocked at how much he wants to kiss her. He then realizes living close to her as a girl changed his perception of her from an idol to a person he’s fallen in love with.
    It wasn’t like this before. I’ve never felt that way about her. It was more like she was someone who was really special. [...] But after I became a girl, we spent time together and grew closer. That allowed me to see her in a more familiar way. I can see her as Suzu, as a girl.
  • Lucky Charms Title: The series logo renders the Japanese text in a bizarre, incredibly angular font that draws parts of the first character (あ) and the dakuten as equilateral triangles. More subtly, the English title is written in all-caps with all the As drawn in a way that emphasizes their triangular shape. From chapter 50 onward, it outright turns the ‘A’ in “TRIANGLE” to a triangle in the English version.
  • Ludicrous Precision: Suzu asks Reo how long she’s known Matsuri, and she instantly answers down to the exact number of seconds.
  • MacGuffin: The god-sealing scroll becomes something Shirogane seeks to restore his power for the first two volumes, and Matsuri must keep from him, least he become unable to stop him from eating Suzu.
  • Magitek: Exorcist ninja use equipment and have devices that seem to be based on the same powers as their ninjutsu. Reo even says her computer-linked training robot was powered by a “jutsu”.
  • Magnetic Medium: An ayakashi medium’s high level of Life Energy attracts ayakashi, but also gives them the ability to see them. Most people who can see the spirits are not ayakashi mediums, and thus lack their level of “magnetism”, but their ability may still be exploited by tricksters looking to antagonize them or even very-violent spirits who want their victims to know why they'll die.
  • Making Love in All the Wrong Places: As Shirogane’s shrine was getting fewer visitors, it became quite the Makeout Point, made worse by interlopers not being able to see the resident "god" spying their rendezvous. His Gender Bender spell was meant purely to punish them, but the entire village was flooded to make a damn while he was out training.
  • Man, I Feel Like a Woman:
  • Marshmallow Dream: One chapter has Matsuri tasked with getting a Life Energy sample from Suzu while she's sleeping. In the process, Suzu's dream about eating marshmallows causes her to bite and nibble on Matsuri's breast.
  • Marshmallow Hell:
    • Suzu once hugged Matsuri, forgetting she was holding Shirogane, squishing him between their chests. After several pages of them embracing (where he was barely visible), Shirogane angrily bursts himself out from between them.
    • After narrowly avoiding being sucked into a wind vortex, Matsuri lands chest-first on Shirogane, and is initially too injured to get up. This leads to one panel where Shirogane’s round head looks as if it replaced one of Matsuri’s breasts.
  • Meditating Under a Waterfall: Matsuri often strips down to his fundoshi and stands under a waterfall to concentrate (or at least did when he was still male). At one point he does this to calm himself down after Suzu hugs him.
  • The Mind Is a Plaything of the Body:
    • An ambiguous and downplayed example; being turned female hasn’t stopped Matsuri from being aroused by Suzu a number of times, but it still may be reducing his attraction to girls, or at least his willingness to act on it. When temporarily turned male again, he feels a sudden urge to kiss Suzu that makes him realize he’s in love with her. However, it’s possible this was in response to Suzu hugging him, and that he was male at the time was coincidental.
    • When Matsuri suddenly says he needs girls’ clothes, the others wonder if he’s becoming more feminine. Shirogane insists his spell only affects the body, not the spirit. Reo theorizes that Matsuri’s body itself could be making his spirit more like a girl’s, deeply concerning Suzu. As Matsuri’s initial statement was just an attempt to distract Suzu from Garaku, the issue remains theoretical.
  • Mistaken for Romance:
    • Played with; Soga’s misspoken Declaration of Protection to Suzu, and him soon coming to Matsuri’s defense in battle, make her think Soga is in love with Matsuri. Soga actually is physically attracted to Matsuri’s female form, but he doesn’t want to pursue a romantic relationship with him.
      Soga (thinking): Just say it, Soga Ninokuru! “From now on, I’ll stand alongside Kazamaki to protect you!
      Soga (talking): I’ll protect Kazamaki! [...] Because Kazamaki is a colleague! That’s it, bye! (Soga vanishes)
      Suzu (thinking): What was that?! Did Ninokuru just declare that he’s my rival?
    • Upon Suzu meeting Reo, she affectionately embraces Matsuri while saying he was “her first”, making Suzu think she's Matsuri’s New Old Flame, and imagines they could have even had sex together. In truth, Matsuri was instead the first to trust Reo’s craftsmanship enough to use her equipment herself. Then Reo’s next appearance shows she really is infatuated with Matsuri, though he hasn’t noticed, and Reo herself doesn’t think she has much of a chance of dating him.
    • Lu and Yayo also see Soga as a potential boyfriend for Matsuri after Soga scares away two boys that were bothering Matsuri. They frustrate Suzu with how on-board they are.
    • Upon learning Reo and Soga are Childhood Friends, Yayo and Lu see a Childhood Friend Romance between both as an inevitable threat to Soga and Matsuri hooking up. Hilariously, this gets Matsuri worried, because he believes Yayo's claim that a "girl" like him can't be friends with Soga when he has a girlfriend.
    • Ponosuke sees Ibuki fixating on Matsuri and concludes she’s Hot for Student. She was actually interested because she’s Matsuri’s mother in disguise
  • Modesty Towel: While in Tanumaro’s illusion, Matsuri sees Suzu wearing a towel in the bath, which conceals her crotch, and partially covers her breasts and butt. Matsuri himself just gets a hand cloth draped over his groin, which the illusion of Suzu quickly takes off.
  • Motifs: Yin and yang. The kon and haku energies correspond to yang and yin, respectively. Matsuri was originally male, has white hair, and manipulates kon for ninjutsu. Suzu is wholly female, has black hair, and manipulates haku. One of the color pages even has the two curled together head-to-foot, visually evoking a taijitu.
  • Mourning an Object: Matsuri stops wearing fundoshi as part of his training, making him realize the comfort they’d brought him. After he finalized his decision, Matsuri bids fundoshi a tearful farewell, gazing at a sky it appears in.
    Farewell, my fundoshi. Until the day we're reunited...
  • Mundane Utility: Suzu uses her Self-Duplication power to wash her back. She herself acknowledges that it's not very impressive, but still useful.
  • Musical Theme Naming: Suzu’s name means “bell”, while her brother Ritta’s name is spelt with the kanji for “rhythm”, which is also used in the word for “melody”. The cafe their parents operate is called “Melody Bell” (in English).
  • Mutually Unequal Relation: Soga constantly calls Matsuri his "rival", and though he doesn't mean that in an antagonistic way, he still thinks they're competing against each other to become stronger. Matsuri doesn't contest this, but also doesn't act like they're in any kind of competition, acting very deferential and atypically candid to Soga. He's even sometimes so adoring as to repeatedly be mistaken as Soga's girlfriend.
  • My Eyes Are Up Here:
    • During a jog for P.E., two male students brazenly stare at Matsuri’s bouncing breasts. He’s inwardly disgusted at them, and prepares to tell them off. Yayo and Lu ward them off first, and they run off apologizing.
    • Another occasion involved a body part besides breasts and had a third person doing the call out: Suzu trips and pulls Matsuri’s fundoshi down, giving her a closeup view of his crotch as he again changes from male to female. Shirogane furiously points out that she keeps staring even as both yelp in surprise.
      Shirogane: What are you talking to?!
      Suzu: N-no! I had water in my eyes, so I couldn’t see anything!
      Matsuri: (thinking) She saw it both ways...
  • Mythology Gag:
    • The cover of chapter 37 has Matsuri wearing the same winter jacket and leggings plus a similar scarf to the ones Fuuka wore in the oneshot.
    • Matsuri’s equivalent in the oneshot was named “Reo (獅雄)”. Reo and her father Shishimaru’s names reference this in opposite ways: the former has the same pronunciation, but is spelled with different kanji. The latter begins with the same kanji, but pronounces it differently.
  • Nice Job Fixing It, Villain!:
  • Ninja Log: Parodied; Suzu kicks Matsuri, who switches places with a log the moment after taking the hit. She questions the point, and Matsuri replies that he didn't want her to hurt her leg kicking a log.
  • Ninja Pirate Zombie Robot: Matsuri and other characters are exorcist ninja. They have the outfits and fighting abilities associated with ninja, but specialize in sealing, purifying, and banishing dangerous spirits.
  • Nipple and Dimed: Downplayed; female nipples are only fully drawn in the collected volumes, but even the serialized version often shows their outlines with some light shading for the areola.
  • No Communities Were Harmed: Omiko is loosely modeled after Odawara.
  • No Ontological Inertia: Shirogane’s spell that turned Matsuri female is a complicated example: On one hand, it works without any involvement of Shirogane himself; if he dies or is severely weakened, that simply prevents him from removing it. On the other hand, the transformation must be constantly maintained by the mark on Matsuri’s stomach. Draining a person’s haku is usually fatal, but in his female form, Matsuri would simply lose what’s being used the by mark, temporarily incapacitating him and restoring his male form until the mark replaces it again.
  • Nobody Calls Me "Chicken"!: Reo tricks Soga into testing her Supernatural Fear Inducer by suggesting he couldn’t handle being scared of Matsuri.
    Soga: Don’t be ridiculous! He’s my rival. I’m not going to be thrown off by some sticker!
    Reo: Yay! (thinking) He’s so easy.
  • Non-Indicative Name: Confusingly, spiritual energy (kon) is entirely absent from spirits like ayakashi; they only contain life energy (haku).
  • Non-Uniform Uniform: The dress code at Hokusai High School always has a white dress shirt, black skirt/slacks, and a tie, but there are several variants for outerwear: Matsuri, Yayo, and Soga wear black jackets. Suzu (after the first three chapters) wears a black cardigan, while Lu wears a tan one. Matsuri also replaces the tie with his ninja suit choker, and undoes enough shirt buttons to show it and some cleavage.
  • Not a Date: In chapter 9, Suzu invites Soga to lunch at her parent’s cafe, which Ponosuke guesses is a date. She was actually inviting both of them, along with Matsuri and Shirogane, to ask for advice in helping the latter pair get along. Shirogane and Matsuri don’t come, and Suzu’s parents can’t see Ponosuke, so they assume she’s dating Soga and are too busy to hear otherwise. Outside, Matsuri and Shirogane spy on them, knowing the meeting wasn’t meant as a date, but suspect it could turn into one.
  • Not Hyperbole: Matsuri precedes his fight against Sosuke with the line “I’ll open up a windhole in your stomach.” After Matsuri fires a wind ninjutsu into the giant mouth Sosuke uses to absorb haku, tearing him up from the inside, Matsuri points out he managed exactly what he promise.
  • Not What It Looks Like: Ritta walks in on his sister laying in bed with Matsuri, whose shirt is open. Ritta runs out and apologizes for bothering them while Suzu insists it’s not what he thinks. Suzu was actually trying to use her powers to change Matsuri back into a boy, albeit in a way that’s a lot like sex.
  • Now That's Using Your Teeth!: With Matsuri’s right arm disabled, he uses his left to throw his scabbard, holding the end of an attached rope with his teeth to swing it around Sosuke.
  • Oblivious Guilt Slinging: Muga accuses Matsuri of distracting his son, leading him down a “path of impurity”. Matsuri, having failed to notice Soga’s infatuation, insists “there’s nothing impure” about their relationship, eliciting an audible sting of guilt in Soga.
  • Once per Episode: Most chapters features a panel with a prominent view of Shirogane’s testicles.
  • Orifice Evacuation: An indirect example occurs in chapter 11 when Matsuri expels an ayakashi possessing Lu. Rather than coming directly out of her mouth, it comes out of the pinwheel Suzu placed in her mouth, almost like it were a straw.
  • Origins Episode: In chapter 29, going through a convoluted Zany Scheme to speed the development of Suzu’s power makes Shirogane question what he’s doing in his life, thinking back to how he got to his current state from being treated as a god.
  • Orwellian Retcon: The collected volumes slightly redraw things to match later chapters, and not just in terms of artstyle:
    • Some panels from the first two chapters add Matsuri’s ninja suit choker, keeping with how he wears it even while bathing and sleeping from chapter 3 onward.
    • Matsuri’s casual outfit in chapter 1 is slightly redrawn to match how it would look when it was next seen in chapter 14.
    • Suzu’s hair at the end of chapter 1 and throughout chapter 2 is redrawn to match the fuller, rounder style she has from chapter 3 onward.
  • Ouija Board: Kachofugetsu play a game where they put their fingers on a coin, asking Shiromatsu use it to answer their questions. Matsuri lets Suzu know he’ll move the coin, as "Shiromatsu" looks like his male side. Shirogane (who’s "actually" Shiromatsu) uses telekinesis to interfere once Yayo asks about Soga and Matsuri, as he wants Suzu to worry Soga is a romantic rival. Matsuri notices him but Suzu doesn’t, and turns it into a game of tug-of-war over the coin. The game is mostly based on Kokuri-san (there’s an open window Shirogane stands in, Lu does the chant but with "Shiromatsu/Shiroma-sama" replacing "Kokuri-san", and there’s a drawing of a UFO instead of a tori), but the English version makes the comparison to a Ouija board.
    Suzu: Isn’t this a Ouija board?
    Lu: Shiromatu’s thoughts in space reside in this ten-yen coin...
    Suzu: So it is a Ouija board.
  • Overly Stereotypical Disguise: Matsuri disguises himself in chapter 9 as a (different) girl, affecting an obnoxiously cute act where he talks loudly, giggles, and proclaims his enthusiasm with a heart in his speech bubble. Suzu saw through it instantly, and her mother at least found him incredibly conspicuous.
  • Page-Turn Surprise: Several inane things are comedically overplayed by having them appear on the first panel of a pair of pages:
    • As Matsuri refuses to let Soga exorcise Shirogane, one page ends on Soga threatening to use force. The next starts with Soga getting flustered from looking straight up Matsuri’s skit.
    • As Matsuri dismisses the need to befriend Yayo and Lu, the page ends on Matsuri turning in shock. The first panel of the next page is Suzu shaking her head with a very pouty face, which makes Matsuri reconsider.
  • Painting the Medium: An ayakashi's speech bubble having a thick border indicates their speech is inaudible to most humans. Ayakashi in humanly-visible forms have regular speech bubbles.
  • Paper Talisman: After Matsuri captures Shirogane, he wraps his body in a ball of paper talismans and throws an extra one on his face. In a later incident, Matsuri also puts two more talismans over Shirogane’s mouth to keep him quiet, but Shirogane manages to tear through them all when Matsuri isn’t looking.
  • Partial Transformation:
    • Reo’s attempt to neutralize Matsuri’s curse with aromatherapy only manages to remove his breasts, leaving him still female otherwise. They’re still impressed that the first attempt would work so well, until the mark rebounds a few hours later and makes Matsuri’s breasts larger than ever for the rest of the day.
      Matsuri: So heavy...
    • When Shirogane gets a cold, Matsuri momentarily regains his penis, but nothing else changes.
      Matsuri: It looks like... I have both?!
  • Pilot: The manga is loosely based on a (very short) oneshot titled Reo × Leo. It shared the premise of a romcom between a girl and girl-turned-boy, and their appearances are similar to Suzu and Matsuri. However, it featured Supernatural Martial Arts instead of ayakashi (Matsuri’s equivalent was transformed by a Pressure Point) while the main duo had completely different names and personalities.
  • Please Don't Leave Me: Yayo and Lu don’t think a girl like Matsuri should talk casually to Soga if he started dating someone else. Matsuri immediately believes them, and goes to pour his heart out to Soga about how important talking to him has been.
    Even if you get a girlfriend, I want us to stay friends, so we can talk about anything with each other!
  • Poor Communication Kills: For years Suzu resented the distrustful attitude Matsuri developed toward ayakashi, because Matsuri never told her that some ayakashi would inevitable begin targeting her specifically. Matsuri didn't think there was any good way to explain "your body makes monsters want to eat you", but Suzu still chews him out.
  • Pose of Supplication: Utagawa bows his head down to the floor after Matsuri defeats him, insisting his attempt to take the god-sealing scroll was just a way to test their powers.
  • Post-Modern Magik:
    • The Exorcist Ninja Association sends out information to exorcist ninja via a smartphone app, giving warnings of elevated chance of dangerous ayakashi much like a severe weather alert.
    • Ayakashi are empowered by human belief and worship. While modern science and technology have weakened most by reducing superstition, Garaku gets over this by becoming famous under his human guise. Thanks the scope of audience mass media reaches, the power this grants him is enormous.
  • Potty Dance: When Matsuri accidentally goes into the boy’s bathroom, his hand is on his groin and his legs are pushed together, showing he was in too much of a hurry to pay attention.
  • P.O.V. Cam:
    • While both are at a cafe, we see Soga’s viewpoint as he drinks coffee and watches Suzu happily eat a parfait, his hand shaking at the sight of her.
    • As Reo crawls over Matsuri’s body to get his scent, we see her through Matsuri’s POV, looking down with his breasts taking up the bottom of the panel.
  • Power Misidentification: After Matsuri punches Sosuke, the arm he used is paralyzed, and Sosuke claims he can eat haku on contact. In response, Matsuri binds Sosuke arms before going in for a sword thrust, only to learn the hard way that Sosuke’s power has considerable range.
    Sosuke: You're too gullible for your own good, Matsuri Kazamaki. I lied about being able to devour the haku of those I touch. It's done in a different way. Jinyo are the ayakashi that are most similar to humans. So you shouldn't trust me so easily.
  • Pronoun Trouble:
    • Usually, characters in the English version of the manga use “he/him” pronouns for Matsuri unless they believe or are pretending he was always a girl, typically when at least one side of the conversation is ignorant of the supernatural. However, one chapter is based on Rochka and Ungaikyo assuming Matsuri is a girl without being corrected, so their conversation with Suzu awkwardly avoids either vocalizing any gendered language.
    • Some other official sources have used “he”, “she”, and even “they”.
    • Averted in the Japanese version, where Matsuri retains his very masculine speech even when presenting himself as a girl. No one believes anything like a spontaneous magic sex change is possible, so they just accept that “she” is a tomboy.
  • Purple Is the New Black: Matsuri's ninja outfit is most likely black, but color pages show it as dark purple with lavender lining.
  • Quest for Sex: Suzu’s initial overarching goal is to make Matsuri male again, both because he wants to change back, but also because Suzu thinks it's necessary to start dating and having sex with him (though she’s also considered dating him even if he stayed female). Eventually she starts seeing her duty as ayakashi medium as important even separate from Matsuri’s entirely, but her sexual goals become even more explicit.
  • Race Name Basis: Matsuri expresses his disgust at Sosuke’s misdeeds by only addressing him as “jinyo” (or “it”).
  • Rebel Relaxation: Matsuri’s leans against a school window as he worries Suzu will end up with Garaku.
  • Rescue Arc: The manga’s first solid Story Arc involved rescuing Suzu from Sosuke, a humanoid ayakashi that wanted to eat her. It’s a rather no-frills example, as Matsuri manages to reach the Arc Villain within a chapter of the kidnapping.
  • Reincarnation-Identifying Trait: An odd metaphorical example. Garaku describes someone he knew as "surrounded by flowers, birds, the wind, and the moon—all the beauties of nature". Said phenomena are collectively known as "Kachofugetsu", exactly the name of Suzu’s group of friends. It’s one reason Garaku knows Suzu’s ayakashi half was passed down from the women he knew back then.
  • Reincarnation Romance: Played with and invoked; Garaku became Suzu's mentor because he fell in love with her past life, Mei, and hopes to see her again by awakening Suzu's power. Despite neither showing romantic interest in the other, Matsuri is convinced they're bound to hook up because that's what always happens in manga.
  • Reinventing the Telephone: Matsuri’s arm bangle transmits sounds back and forth from a breadbox-sized device with a tuning fork receiver. Humorously, it’s first shown in combination with a regular cellphone for a three-way call between Suzu, Seigen, and Matsuri.
  • Relationship Sabotage:
  • Relatively Flimsy Excuse: Garaku claims Rochka is his niece to explain her living in his studio in human form.
  • Relax-o-Vision: Matsuri ends up exposed to Rochka when partially made male again. The following panel shows the cresting of a bowhead whale.
    Meanwhile, in the Arctic Ocean...
  • Reveal Shot:
    • Reo falls in front of Suzu's crotch, then starts smelling it. The next page starts with a zoom in on Reo grabbing a body part that looks like the folds of a woman's bare genitals. The panel below zooms out to show Reo was holding Suzu's leg, which had her knee bent to the point her thigh and calf were touching.
    • After Matsuri tackles Soga to the ground to talk to him, the panels only show their faces and upper bodies up close. Once Matsuri is finished talking, the view zooms out to show Matsuri landed his crotch directly in front of Soga's face, which Matsuri didn't previously notice.
  • Right for the Wrong Reasons: Matsuri initially catches Shirogane spying on Suzu, and rightly assumes he was up to no good. However, Matsuri had been treating practically every ayakashi around Suzu this way, and had no idea Shirogane was hiding his true power.
  • Right Through His Pants: In a very strange invocation, Suzu and Matsuri’s G-Rated Sex has Matsuri’s upper half only covered by his bra, but Suzu remains fully-clothed (though the audience gets a Panty Shot). It’s one of several things that peg Suzu as having a dominant “male” role between the two.
  • Rule of Symbolism: After trying to suppress his romantic feelings for Matsuri, Soga is only able to prove their ability to his father by literally having Matsuri cling to him to provide a speed boost. In the process, Soga is amazed that, far from feeling dragged down by Matsuri’s weight, he feels lighter carrying him around. It’s a clear sign that whatever kind of feelings he has for Matsuri, Soga shouldn’t see them as weighing him down, but lifting him up.
  • Running Gag: Several times when Suzu and Matsuri realize they’re in a suggestive situation, they give a soft sigh of surprise in unison a moment before reacting in a much more extreme way.
  • Samaritan Relationship Starter: Suzu and Matsuri met as children when he was being chased by an ayakashi, which she instantly called off him. Matsuri wasn’t only grateful for her help, but very impressed by her command over the ayakashi, so much that he practically worships her. Ironically, Matsuri doesn’t seem to remember this event.
  • Same Clothes, Different Year: A flashback in chapter 4 shows a young Suzu wearing a hoodie as she does in the present, except it's black instead of white.
  • Scenery Censor: The inky-black black, ephemeral ikon possessing Lu in chapter 11 just barely covers her and Yayo’s crotches and nipples. Suzu takes notice, and seems to find it more embarrassing to look at than plain nudity.
    Suzu: Convenient coverage in just the right spots...
  • Science Destroys Magic: Zig-zagged; humans used to believe ayakashi responsible even for natural phenomena, which ended up creating more of them. As science gave the average person a better material understanding of nature, they’ve come to disbelieve the supernatural, even when they encounter it, so fewer ayakashi are being created. However, not only have the older ayakashi remained, there are new types (such as ikon) that are only now being created by modern society.
  • Second Law of Gender-Bending:
    • Matsuri barely minded living as a girl in the first place, and it directly led to him repairing his friendship with Suzu, improving his social life, and realizing he was in love with Suzu. Far from causing him to like being a girl, the last point intensified his Gender Bender Angst, as now Matsuri thinks he's missing out stuck as Suzu's "girl friend". However, there is obvious potential for a Double Subversion, as unbeknownst to him, Suzu has seriously considered dating Matsuri anyway.
    • At one point, Reo and Suzu wonder if Matsuri might eventually identify as female, and discuss how that would affect their feelings for him. Reo is completely undisturbed, as she never cared about Matsuri's gender. Suzu initially agrees, even if she clearly finds Matsuri more attractive as a guy. But seeing Matsuri dressed up in a very feminine way—and Soga awestruck at the sight of him—makes Suzu think she has to stop Matsuri from becoming a girl "in spirit" as well as body.
  • Secretly-Gay Activity:
    • Suzu convinces Matsuri that him becoming female means it's normal for them to get physically closer than they were before, like sitting shoulder-to-shoulder on the school bus. The audience can see from Suzu's thoughts that she's enjoying such closeness because she's still attracted to Matsuri. As Matsuri is already unsure Suzu loves his male form, her obliqueness causes Matsuri to believe she'd never love if he can't change back.
    • Analyzing the spell on Matsuri required Reo to carefully observe how it changed his scent. In the process, she suggestively crawls all over him, pulls his shirt off, and even grabs his breast to pull his bra down and smell his armpit. Despite practically admitting it was something she wanted to do even separate from the task at hand, Matsuri still doesn't get it.
  • See the Invisible: When looking for an ayakashi too weak for even him to see, Matsuri scatters the ashes of burnt paper talismans and looks for what they collide with in midair.
  • Self-Serving Memory: Before seeing Suzu casually surround herself with ayakashi, Matsuri was deathly afraid of them. Judging by his reaction when his grandfather pointed it out, Matsuri had completely forgotten this.
  • Series Fauxnale: The Jinyo arc was likely written as a potential end for the series. It leads to Matsuri restored to male form and realizing he’s in love with Suzu, resolving a good part of the manga's major conflict... but for the important details that Matsuri goes back to being female after a few hours, and Shirogane no longer has the power to change him back. Shirogane even interrupts Suzu and Matsuri's hug to declare “You're still a far cry from a happy ending!”
  • Sex Comedy: Quite a lot of the sexual content is (also) a device for raunchy comedy.
  • Sexy Soaked Shirt: When Matsuri is Meditating Under a Waterfall in only his fundoshi, Suzu decides to take off her sweater and come in to talk. Matsuri quickly picks up on how visible this makes her bra through her undershirt.
  • Shadow Discretion Shot: Parodied when Rochka sees Matsuri's crotch during a brief moment where he’d become a hermaphrodite. Her body is covered by a phallic shadow, but the comically improbable size and positioning indicate it's the shadow of something else, like Matsuri's entire body.
  • Shape Dies, Shifter Survives: Sosuke seemingly kills Matsuri by draining all his Life Energy, but at the last second Matsuri reveals he has survived and even been reverted to male form. Shirogane then explains Sosuke only ate the energy sustaining the transformation, temporarily reversing it.
  • Shapeshifter Guilt Trip: A more benign example; Shirogane shapeshifts into Matsuri’s male form to beg Suzu for more dumplings. She fully knows it’s an illusion, but finds it too frustrating to endure.
    Shiromatsu: Please, Suzu? I need... your dango...
    Suzu (thinking): (trembling) Don’t whisper in my ear!
  • Shared Universe: Ayakashi Triangle is evidently set in the same world as To Love-Ru, or at least has its own version of several characters. Run and Kyouko have appeared on various in-universe media, and Seigen appears to be a fan of the former. Matsuri’s favorite manga was written by Rito Yuki’s father Saiba, and Lu is a devout reader of his as well. Ren’s classmate shows up at an art museum, and talks Matsur’s ear off about Garaku’s career.
  • Short-Distance Phone Call: One scene has Suzu and Shirogane seemingly alone in Suzu's room when she gets a text message. We then see Matsuri sent the text while hiding in the same room under an Invisibility Cloak. They were making Suzu appear unguarded, to bait out someone trying to attack her, and texting this way keeps him hidden.
  • Shout-Out:
    • The title of chapter 7 is The Melancholy of the Ayakashi Medium.
    • The day after Suzu and Matsuri disappear from school in the middle of the day, Lu jokes about them getting kidnapped by Chronos, the criminal syndicate in Black Cat.
    • In a flashback to Matsuri playing with Tanumaro, they’re reading an issue of Shonen Jump with Kochikame on the cover.
    • Lu performs the Vulcan salute from Star Trek on the cover of chapter 26 and while trying to talk to Shiromatsu.
    • Lu writes her notes about extraterrestrials down on a notebook labelled “L-File”.
    • Shirogane, taking Matsuri’s male form, introduces himself to Lu as "Shiromatsu", which she says sounds like one of the Matsuno brothers from Osomatsu-kun.
    • Shirogane’s Feline Thunder Clap involves generating Static Electricity with a pencil board just like Kagechiyo from Ninja Hattori. Shirogane even calls it a technique passed down by “generations of cats”.
    • Reo’s “disc-type” machine to modify exorcist ninja battlesuits is modeled after the Famicom Disk System disc-rewriting kiosks.
      Kentaro Yabuki: Anyone who understood the reference with the transfer machine Reo brought out is probably the same generation as me.
    • Matsuri’s Bond One-Liner to the Hiderigami is “Date ni ‘onna’ yattenē ze!!” (officially translated “I'm not a girl just for show!”), a parody of Yusuke’s "On the Next Episode of..." Catch-Phrase in Yuyu Hakusho “Date ni anoyo wa mitenē ze!” (“I didn’t see the afterlife for nothing!”).
    • After seeing Suzu's paper servants lift her through the air by the feet, Yayo shouts out "Iron Man!?"
  • Ship Tease: Even though Soga doesn’t want to act on his attraction to Matsuri and Matsuri shows no signs of reciprocating, the manga frequently emphasizes the idea of them as a couple. Several characters want them to hook up, they tend to get in suggestive situations together, and Matsuri grows to adore Soga in a very enthusiastic manner. In particular, the possibility of Soga getting a girlfriend causes Matsuri to beg for them to stay friends regardless, which is framed like an Anguished Declaration of Love (Matsuri uses Soga’s given name for the first time, says how much he means to him, and is blushing on the verge of tears by the end).
  • Sir Not-Appearing-in-This-Trailer: To conceal the First-Episode Twist, initially advertising and the first volume cover show Matsuri only in his male form, even though he spends the vast majority of the series female (his original form occasionally showing up in flashbacks or mental images). The table of contents for Weekly Shonen Jump even used a closeup of male Matsuri’s face for almost half a year, and only changed it along with all the others at the start of the next publishing year.
  • Speech-Bubble Censoring: One Shower Scene has Suzu covering her breasts with her hands, but her genitals are only obscured by her speech bubble. This of course doesn’t prevent Matsuri from seeing anything while in the room, as he stares straight down.
  • Skewed Priorities: Matsuri has a very stringent view that couples save themselves for marriage, even for a simple kiss. When Yayo talks about a Show Within a Show where a man-turned-dogman can only change back with a True Love's Kiss, Matsuri says they should still get married first. If being a dog prevents that, Matsuri says he’ll just have to hold in his feelings and live as a dog for the rest of his life.
  • Skinship Grope: Invoked when an ayakashi puts Matsuri under an illusion to blackmail Suzu over releasing it. Since his grandfather had joked about Suzu washing Matsuri off in the bath, he imagines her doing just that, thoroughly feeling him up in the process.
  • Skirts and Ladders: Matsuri’s dramatic posing while Sky Surfing above Soga ends up providing Soga with a very clear view up Matsuri’s skirt, both because of the altitude and wind he was creating. After Soga runs off, Shirogane has to explain to Matsuri why.
  • Sickening "Crunch!": After Sosuke shoves a small ayakashi in his mouth, the Written Sound Effects make it clear that it was not Swallowed Whole.
  • Spooky Photographs: In chapter 10, Lu takes a picture that an ayakashi shows up in. Unfortunately, the specific type is an ikon, whose image alone causes Lu to be possessed.
  • Slippery Skid: Ponosuke spilling a box full of azuki beans instantly causes Soga and Matsuri to trip and fall on each other, to the former’s consternation.
  • Slut-Shaming: Shirogane sees Suzu as promiscuous for meekly implying she'd like to have sex with Matsuri, calling her a slut for it... and also because she has a great technique for petting small animals like him.
  • Stab the Salad: After Matsuri seriously injures the Hiderigami, Suzu seems to jump in to finish it off with a swarm of origami. However, the origami instead bundle up around the ayakashi's wound before Suzu channels her healing powers through it.
  • Staircase Tumble: Yayo spends chapter 6 possessed by an ayakashi that periodically makes her trip. After a few Suggestive Collisions, it ultimately causes her to tumble headfirst down a flight of steps, but Matsuri is able to catch her before absorbing the impact with a Two-Point Landing.
  • Stealth Sequel: Sort of. Initial advertising made no mention that Ayakashi Triangle is a serialization of the Reo × Leo oneshot, which was only explicitly confirmed in the author’s comments for the second chapter. Partly this was to conceal the First-Episode Twist, but also because the oneshot had been very heavily retooled and was quite obscure to begin with.
  • Strangely Arousing: While an ayakashi wraps Suzu in silk strands (which turns out to just be a tailor taking her measurements), she tells Matsuri to stand by instead of antagonizing her. Matsuri reluctantly complies, but is uncomfortably aroused by the way the threads undress and suggestively squeeze Suzu, earning a Dope Slap from Shirogane.
    Shirogane: What kind of kinky stuff is this?! Stop it already!
  • Sue Donym: While taking Matsuri’s (male) form, Shirogane goes by a portmanteau of their names, “Shiromatsu”.
  • Sufficiently Advanced Bamboo Technology: Exorcist ninja gear maintains an old-fashion Japanese aesthetic even for highly-advanced Magitek. Reo’s training robot has a camera eye and computer uplink, but it’s made largely of wood and its interior is full of gears and chains. Even her tablet computer appears to use wood in place of plastic.
  • Sufficiently Analyzed Magic: Exorcist ninja Magitek is based on reverse-engineering ayakashi's magical items. Reo specifies her Invisibility Cloak is a recreation of a tengu's. This is used to explain how Suzu's ayakashi-made costume has abilities nearly-identical to Matsuri's.
  • Suggestive Collision:
    • Chapter 6 starts with Yayo tripping into Matsuri’s legs, and she accidentally grabs Matsuri’s butt and looks up his skirt while trying to brace herself. Yayo has a history of groping other girls, and has recently grabbed Matsuri’s breast, so she has a hard time convincing Matsuri it was an accident.
    • In chapter 11, Suzu tries to cover Matsuri’s eyes so he won’t see other girls while they’re all naked in the bath. She ends practically on top of Matsuri, with her hands grasping his hair and bare breasts pressed into his back. When Yayo laughs at how close they are, Matsuri hurries out of the water and Suzu assures him it was just an accident.
    • Suzu’s attempt to control her stuffed animal with haku causes it to wildly flail around, landing her and Matsuri on her bed, with Suzu’s hand on his hip and knee in his crotch. For incidental reasons, a very suggestive scene follows.
    • After both slip on a bunch of azuki beans, Matsuri ends up with his breasts in Soga’s face while straddling his crotch. Suzu was so shocked to see them, the omokage she was watching them through vanishes.
  • Supernatural Fear Inducer: Reo’s Spooky Sticker will make whoever it’s stuck to afraid of the person whose name is written on it. She made it to chase off guys harassing Matsuri, and talks Soga into testing it.
  • Supernaturally Delicious and Nutritious: Ayakashi mediums are people born with an extremely large amount of physical Life Energy. This makes benign ayakashi more receptive to them, but also makes malevolent ones want to devour them to gain power.
  • Surprisingly Realistic Outcome: In chapter 9, Matsuri tries to disguise himself in front of Suzu and Soga by donning a black wig and affecting a very conspicuous personality. Everyone in the room instantly recognizes him.
  • Surrender Backfire: Utagawa starts to back off from taking the god-sealing scroll when Soga informs him he could incur the wrath of the Exorcist Ninja Association, but Soga tries to strike him down anyway. Utagawa comes out ahead because he was able to rapidly counter with a trap (he turns out to have been messing around without trying to hurt anyone, so the surrender itself probably wasn’t a feint).
  • Swapped Roles: Suzu often tries to reign in Matsuri accidentally showing off his female body, including warning him to watch his skirt while going up the stairs, all the while concealing her own sexual attraction to him. But when the weather turns incredibly hot, Suzu is so exhausted she collapses on the steps and lifts her skirt up in an attempt to cool herself off. Matsuri, of all people, is uncomfortably aroused and warns Suzu that she needs to act more proper.
  • Symbol Motif Clothing: The symbol of the Kazamaki clan is a ninja star overlapping a pin wheel, and either it or its parts are seen variously on their clothing (for instance Matsuri has a ninja star both under the neck of his exorcist outfit and on the collar he starts wearing as a girl).
  • Synchronization: Certain things that happen to Shirogane affect Matsuri because of the spell the former cast on the latter. When Shirogane gets a cold, Matsuri can feel the spell mark burning, eventually collapses in a sweat, and momentarily has his transformation slightly reversed.
  • Tamer and Chaster: Compared to Kentaro Yabuki’s previous work as artist for To Love-Ru, Ayakashi Triangle is both more and less sexual: On one hand, the Fanservice isn’t as big a focus, and many chapters have fairly little. On the other, the graphic and sexual intensity of many scenes is higher (almost on the level of Darkness, To Love Ru’s Hotter and Sexier sequel in Jump Square). Regardless, it is much Hotter and Sexier than Black Cat, the last series that Yabuki actually wrote.
  • Tastes Like Purple: Reo describes Suzu as having a "sweet, lusty scent", whereas Matsuri’s is "sporty".
    Suzu: (smelling herself) Lusty?
  • The Teaser: A print example; many chapters have an illustration with a title on the second page, making the first page a separate scene without any credits. The main exception is color pages, which have to go first because they’re printed on a different type of paper than the rest.
  • Teeth-Clenched Teamwork: Matsuri and Shirogane hate and bicker with each other even after they begin living together, but gradually learn to work together for the occasional Enemy Mine.
  • Terra Deforming: Garaku had to paint a sacred tree from memory because the entire area was logged bare in the Meiji era. New trees were planted afterward, but it comes off less as nature returning than people throwing a coat of paint over destructive development.
    Garaku: At that time, lumber was the main source of building materials and fuel. All the woodlands in Japan were laid bare. All the greenery you see here was planted after that time.
  • Testes Test: A few hours after Reo’s attempt to cure Matsuri removes his breasts, Matsuri puts a hand each on his chest and up his skirt to confirm nothing else has changed.
  • Theme Naming: Suzu, Yayo, Matsuri, and Lu have last names beginning with kanji for natural phenomena (flowers, birds, wind, and the moon, respectively). They stick them together to name their group “Kachofugetsu (花鳥風月)”, a phrase for the artistic beauty of nature.
  • Thanks for the Mammary: Rochka freezing the ground under Suzu causes her to fall over and brace herself by accidentally grabbing Matsuri's breasts. For Matsuri, the most embarrassing part was the high-pitched squeak he made in response.
  • That Was Not a Dream: Yayo gains the ability to see ayakashi and wonders if an ensuing fight Matsuri and Suzu have with one is just a dream. Matsuri considers pretending it really was one, but Suzu shoots him down, realizing that would just cause more problems.
  • Third Law of Gender-Bending: Matsuri identifies as male regardless of his transformation, feels no obligation to act feminine, and generally can’t fit in with girls even when he tries. However, he’s living under a female identity, which has lead him to adopt some behavior associated with girls:
    • His school uniform includes a short skirt, and despite his initial complaints, he never tries to wear anything else, or even hurries to change out of it after school. It is by far the outfit Matsuri’s shown in the most, even though the only other change to his wardrobe was adding a sports bra, as much of the manga takes place during or close to school hours. He even tends to forget to change into his ninja suit for battle, despite being able to do so instantly.
    • When Shirogane sees Matsuri serving breakfast in an apron, he concludes his spell is making Matsuri more feminine, which he remarks upon as a terrible fate. Matsuri defensively insists he was already doing these kinds of chores for his grandfather, though he doesn't mention if he wore the apron before.
    • Lecherous boys tend to effect a fairly prudish response from Matsuri. More than once, he’s spoken in anger condemningly about “boys”, literally forgetting his own gender for a moment.
      Matsuri: (thinking, as two guys stare at his chest) It’s so obvious where you’re looking. Do they think we can’t tell? Guys are so stupid! Wait, I’m a guy.
    • At one point, Matsuri is in a rush to distract Suzu with an errand, and randomly blurts out he needs girls' clothes. Though still uncomfortable in anything more than the aforementioned school uniform, Reo's inhibition-loosing incense lets Matsuri enthusiastically fly through a Costume-Test Montage, even as Reo picks out increasingly impractical outfits. Ironically, Matsuri asking in the first place makes Reo and Suzu wonder if his female body is making him act more feminine.
    • After a few months, Matoi convinces Matsuri to switch from fundoshi to girls’ underwear as part of his training. Which conveniently aligns with Matoi’s fondness for having a cute daughter.
  • Thoroughly Mistaken Identity: Rochka immediately assumes Seigen is her grandfather because of their strong resemblance despite Matsuri's repeated protests. Matsuri eventually gives up convincing her of the truth because believing they share a grandfather makes Rochka marginally less hostile to him.
  • Through His Stomach:
    • Suzu tries to befriend Shirogane by making good food for him. Shirogane greatly enjoys it because of bits of her Life Energy leaking into the food, which helps get him at least somewhat attached to her.
    • Subverted for laughs the morning after Matsuri starts hosting Shirogane and offers him breakfast. Shirogane starts to wonder if Matsuri is more than the brat he’d assumed… until he sees the “breakfast” is just a rotten pile of food waste.
  • Tickle Torture: When Shirogane takes over Reo’s training robot, it grabs him and sprouts tendrils ending in cotton balls that tickle him all over.
    Reo: Why did the Ultimate Tickle Device get activated?!
    Suzu: Why even have that function?
  • Tomboy and Girly Girl: Matsuri has a rough-going personality as an ayakashi exorcist, has no qualms getting into fights if he's dragged into them and is a former boy who hasn't adapted to being a girl. He contrasts with Suzu, the level-headed, kindhearted, and decidedly feminine ayakashi medium with little to no experience in how to handle herself in a fight. Crossing over with Masculine–Feminine Gay Couple, they have mutual romantic interests that don't stop down after Matsuri is turned female.
  • Too Hot for TV: Viz Media only make the official translation of the manga available on their website, not on the Shonen Jump app, because of its sexual content. Manga Plus, however, has it on both its website and app.
  • Too Important to Walk: Suzu gets carried around in a litter while visiting an ayakashi village. However, the ayakashi doing the lifting are only a couple feet tall, making the ride very slow and awkward—she has to fold her legs up to even fit on the thing.
    Suzu: I appreciate it, but I think I want to get down now.
  • Too Long; Didn't Dub:
    • Much like in Naruto, the English version leaves the term “jutsu” ("technique", in this context often referring to magic spells) untranslated.
    • "Senpai" as a term is left untranslated, though the honorific is just as often left off entirely. (Most of the cast but Soga are on a First-Name Basis with no honorific even in the Japanese version.)
    • The first/cover page and the last panel have captions in the Japanese version that are entirely absent in English. Likely because, though they may provide Previously On… or On the Next information, they tend toward Narrating the Obvious, and aren’t even left in the volume version in Japanese.
    • Lu’s dialogue in Japanese is mostly in katakana to indicate Creepy Monotone, switching to hiragana in more expressive moments. In English, her dialogue is written in the same fonts as everyone else’s.
  • Training the Gift of Magic: Ayakashi mediums are the only humans who can manipulate haku, but they still need to train their ability to do so, preferably with guidance from ayakashi (who always control haku). Manipulating kon is an ability possibly any human can develop, but the only ones we’ve seen doing so are also of the few with an inherent ability to see the supernatural.
  • Trans Equals Gay: Suzu perceives Matsuri and Soga as developing romantic tension since Matsuri became female. She specifically takes it as a sign that Matsuri’s transformation is affecting his gender identity, rather than his sexual orientation. By contrast, Reo would be fine with Matsuri identifying as female, not showing any fear he would thus cease being attracted to girls.
  • Trans Relationship Troubles: At one point, Suzu and Reo wonder if Matsuri might start self-identifying as female, and bring up how that would affect their feelings for him. Reo never cared whether Matsuri was a boy or girl to begin with, so it’s no problem for her. Suzu tells herself she’d still love Matsuri, and only wants to make him male again because she promised she would. However, her fantasizing shows Suzu finds Matsuri much more attractive as a man, and quickly comes to believe a fully-female Matsuri would get together with Soga instead of her.
  • Transformation Trinket: Standard exorcist ninja gear includes some small item called an "outfitting tool" that lets them instantly change into their battle suits, weapons included. Matsuri's is a choker, which he wears everywhere he goes, even while bathing. Soga's is a badge on his shirt shaped like a lightning bolt. Reo’s is a bracelet with a button on the palm side. An ayakashi makes a necklace with the same function for Suzu to put on her ayakashi medium gear.
  • Trap Is the Only Option: After taking Suzu, Sosuke leaves a trail toward his headquarters, as he wants Matsuri’s group to follow and be killed before he eats Suzu. Shirogane is immediately suspicious, but Matsuri decides their only option is to charge in anyway.
  • Triang Relations: Soga, Matsuri, and Suzu form a Type 6. Matsuri and Suzu are both interested in each other. Soga is knowingly in love with Suzu, though he can’t say it to her face, but also physically attracted to Matsuri in a way he can’t come to grips with.
  • Troubled Fetal Position: During the Beach Episode, Soga is too shy to hang with the scantily-clad girls that make up the rest of their party, and so goes off to sit on a rock with his arms folded over his knees.
  • Twice Shy:
    • Suzu and Matsuri have a mutual attraction to each other that each is reluctant to act on for various reasons. Matsuri thinks much more highly of Suzu than himself, and so hides his feelings under the assumption they would burden her. Suzu is only slow forgiving Matsuri for his overprotective history and is uncomfortable (though not completely unwilling) to pursue a relationship while Matsuri is female, though she is actively trying to grow close to Matsuri regardless. This doesn’t make them shy away from talking to each other normally, however, with Matsuri saying Suzu is like family. Matsuri realizes he loves Suzu by the third volume, but doesn’t say it aloud, and seems less comfortable acting on his feeling when he’s living as a girl.
    • In a subversion, Yayo thinks Soga and Matsuri are in love but just too shy to act on it. While this is mostly accurate on Soga's side, Matsuri isn't attractive to him and only acts evasive because he's worried Suzu will get the wrong idea.
  • Two Scenes, One Dialogue: After Grandpa Kazamaki (seemingly) explains Shirogane is a fierce ruler of other ayakashi, we cut to Shirogane (still in his small form) trying to explain the same to Suzu as she rubs his belly.
  • Undead Tax Exemption: Thanks to his work as an exorcist, Matsuri's grandfather has the connections to send Matsuri to school under a false female identity, and even make sure he and Suzu will be in the same class.
  • Unsettling Gender Reveal:
    • When Ritta first sees Matsuri as a girl, he’s shocked that a friend of Suzu’s he assumed a boy was actually a girl who grew up to have such a voluptuous figure. However, the audience knows he is mistaken, and that Matsuri actually was male back then.
    • Played with; although Matsuri doesn't hide that he's a boy from Rochka, she still ends up assuming he's always been a girl. This makes her very shocked when she sees his crotch while he'd partially become male again. However, Rochka still believes Matsuri is a girl and offers to freeze off what she treats like some kind of growth. (She's especially confused because it seems her upbringing left her ignorant of human male anatomy.)
      Rochka: I don't have anything like that!
  • Victoria's Secret Compartment: Matsuri keeps the god-sealing scroll tucked between his cleavage while sleeping. He’s not trying to conceal it (it's actually very conspicuously suggestive), just make it harder to steal without waking him up. When he wants to actually hide it, he keeps the scroll under the back of his sports bra, claiming it’s an heirloom when someone notices it anyway as he’s changing.
  • Visible Invisibility: Ayakashi and related things Invisible to Normals are usually fully visible to the audience, as most of the main cast can see them. Otherwise, they’re fully invisible. Notably, this meant it took some time to reveal most people cannot see the exorcist ninja in their battle suits and the gender swap mark on Matsuri’s abdomen. Humourly, the Hot Springs Episode has an ayakashi visible to obscure Yayo and Lu’s nudity from the front, but not from the back.
  • Visual Innuendo:
    • As Suzu gives Shirogane a belly rub, he thinks of the spiritual energy she's giving off, which is visualized as fluid flowing past her fingertips. However, in the same panel, Shirogane calls her a pervert for her "technique", calling attention to it also looking like a closeup of a masturbating woman's genitals.
    • Matsuri sleeps with the god-sealing scroll tucked between his cleavage, which is pretty absurdly phallic-looking.
    • During Lu’s dream during her exorcism in chapter 11, Matsuri’s (male) apparition holds out the tip of his pinwheel, which she suggestively puts her mouth around.
    • Suzu spends one scene bathing, wondering if an invisible Matsuri is staring at her body while keeping guard. Suzu definitely likes the idea, and as she starts describing how the idea makes her feel, the next panel is a dripping showerhead.
    • Matsuri putting his hands up Suzu's shirt sleeve is used as a very over-the-top penetration metaphor. His arms are even trembling as he slowly puts them in.
  • Waking Non Sequitur: After Suzu regains consciousness from her inner ayakashi power taking over, she bolts up and shouts "Oh! My tiramisu!", which assures Matsuri she's back to normal.
  • Wardrobe Malfunction: While playing in a creek, Ponosuke shows off his ability to pluck fish from the water. Then he grabs a fish lodged in Matsuri’s cleavage, exposing one of his bare breasts to Soga, sending the latter falling into the water with shock.
  • Wax On, Wax Off: Matoi’s training for Matsuri involves strengthening his spirit, and thus body and ninjutsu, by creating emotional adversity. Thus, she decides he should take advantage of his transformation to get away with wearing girly underwear specifically because it would make him uncomfortable.
  • Webcomic Time: The series begins in April (the start of the Japanese school year). It takes nearly a real-life year for time to progress to summer.
  • Weirdness Censor: In the modern day, regular humans tend to quickly forget even visible ayakashi and the effects of their actions. Sosuke made quite a stir when he showed up at Hokusai High School as a student, but by the next day no one but Suzu and Matsuri remembered him. (Ironically, people in the past tended to do the opposite.)
    Seigen: It’s difficult for people who don’t believe in ayakashi to remember one that disappeared. That’s how vague of an existence ayakashi have in the modern world.
  • What Measure Is a Humanoid?: The idea of romance between humans and ayakashi has only come up when involving ones that look human:
    • Garaku looks like a human, fell in love with Mei, and Matsuri views him as a romantic rival over Suzu.
    • Shirogane is normally a cat, but when he shapeshifted into Matsuri’s male form, Lu ends up falling in love with “Shiromatsu”.
  • When You Snatch the Pebble: To prove he had not lost his focus, Soga is tasked with making his father Muga spill the sake from his filled-to-the-brim cup. After failing for hours on end, Matsuri is allowed to join in. Though initially faring no better, even when they both attack together, they succeed when Matsuri uses his wind ninjutsu to make Soga fast enough. This convinces Muga that Matsuri isn’t a distraction, and that the two make a fine Battle Couple.
  • "Which Restroom" Dilemma: Matsuri absentmindedly goes to the boys' restroom instead of the girls' in the third chapter. His teacher angrily comes in, informing us this has happened many times before.
  • Wingding Eyes: After Matsuri defends Suzu from an attack in her bathroom, his pupils look like nipples as he stares in shock at her bare chest.
  • The Wild Hunt: A very benign form of hyakki-yakō is shown while Kachofugetsu run laps for gym glass. Matsuri muses on if Yayo and Lu could see the supernatural, and has an Imagine Spot of many different types of ayakashi running alongside them.
  • Word Salad Title: “Ayakashi” are the spirits the series features prominently, but the meaning of “triangle” is far less obvious. The title of the first chapter (“Matsuri, Suzu and the Ayakashi”) suggests it refers to Matsuri, Suzu, and how the ayakashi affect the relationship between them. Others theorize it refers to Matsuri, Suzu, and Shirogane. The author states he wishes to write about “various types of relationship triangles that go beyond just romance” (possibly in response to guesses that the title refers to a Love Triangle), implying a fairly broad meaning.
  • Wrecked Weapon: Matsuri's surprise attack on Shirogane simply breaks his sword on the cat's hide without doing any damage at all. Matsuri replaces it within two chapters, and it's eventually shown they're literally bought off-the-shelf.
  • Wrong Name Outburst: In a twist on the idea of accidentally calling your teacher "mom", Matsuri starts calling his actual mother "mom" when she was disguised as his teacher.
  • You Can Leave Your Hat On: As Matsuri hides under an Invisibility Cloak while guarding Suzu, Suzu starts undressing in front of him. Suzu claims it’s just to sell the idea she’s alone, but it’s quite obvious she’s exploiting the situation to seduce a very uncomfortable Matsuri.
  • You Can Talk?: Yayo is shocked to hear Shirogane talking, affirming to him they have gained the ability to see ayakashi.
  • You Must Be Cold: After Rochka accidentally destroys her clothes, she ends up falling asleep in Matsuri’s lap, and he takes off his shirt to cover her up. Later, Shirogane and Suzu come in and assume it was a Sexy Shirt Switch.
  • You Wouldn't Shoot Me: After being captured, Shirogane is sure Matsuri won't exorcise him, lest he lose his only way of becoming male again. Matsuri is ready to do it anyway, both to protect Suzu and humanity in general. However, Suzu refuses to let him sacrifice himself as such, so Matsuri takes a third option: keep Shirogane as a "pet" until he can be sure he won't harm anyone again.
  • Zig Zag Paper Tassel: A giant butterfly net Matsuri uses to catch wayward ayakashi has a shide tied around the shaft below the net.
