Unprovoked Pervert Paybacks in Anime and Manga.
- Baka and Test: Summon the Beasts:
- Aiko shows the main cast, girls included, her new cellphone. She then explains clearly it can mix and match voice bites to make new sentences. Akihisa says a perfectly normal phrase in front of everyone and Aiko uses it right there to make it sound like Akihisa just said something naughty. Somehow, that makes Minami and Mizuki, who were present the entire time and clearly should know what's going on as they were paying attention, completely buy that's something Akihisa has said and take him off to painfully torture him.
- The entire second season is filled with this, as well as the male characters being tortured for anything that offends the girls. The closing credits have the male characters fleeing in terror from the kanji for female. Though the first season was worse at points.
- Ben-To: Though Ume Shiraume frequently abuses Yoh Satou for any perceived perverted slight, it's primarily because of her Clingy Jealous Girl crush on Oshiroi, who's always accompanying him. It gets to the point where she'll attack him when he's shown to already be injured or unconscious.
- Early on in Black Clover when Magna gives Asta and Noelle a ride on his broom he tells Asta to hold on, so he innocuously grabs Noelle's waist and she elbows him in the face, nearly causing him to plummet into the lake below. And she was still angry with him after almost killing him for no reason.
- A Certain Magical Index:
- Touma is very good at accidentally walking in on girls changing. This leads to a few examples in the second season where he does absolutely nothing out of the ordinary and still ends up bitten by a furious Index.
- Even when he's unconscious, he can't escape. As demonstrated when his hand is used to destroy the enchantments on Angeline and Lucia's clothes. Which happens to destroy them entirely.
- Once, he gets smacked because a girl walks in on him changing.
- By New Testament 9, he's finally gotten smart enough to stay on completely the opposite side of the store from the changing rooms when the girls drag him along swimsuit shopping. He manages to avoid getting beat up, but due to Hilarity Inevitably Ensuing, ends up mistakenly making the girls think he's into dressing up in girls' swimsuits, which just weirds them out rather than making them angry.
- In A Certain Magical Index: Miracle of Endymion, Index and Arisa are bathing together in Touma's apartment when Arisa suddenly gets inspiration for a new song. The two rush to the living room without bothering to dress so she can write it down. When Touma comes home, they freak out and a furious Index bites him, even though he had no way to know they would be naked in his own living room.
- Happens in Digimon Frontier; two of the Tamers fall down a pit into a heap leading to the following exchange:Zoe: I'm alive! I could just kiss you!
Takuya: Uh...
Zoe: O.O (slaps him) Get offa me!!
Takuya: You're the one who grabbed me in the first place!!! - Full Metal Panic! plays it straight most of the time, most prominently early in the story where Sosuke catches a classmate trying to steal some of Kaname's panties (because some upperclassmen were forcing him to). The two start talking, find common ground, and are having a friendly chat when Kaname finds them...and Sosuke has the panties in his hand. Cue baseball bat to the head. It starts getting averted later on, especially when it comes to Sosuke's CO Tessa, who has a huge crush on him and does things like sneaking into his bed; once Kaname catches them like this and, when a panicked Sosuke insists it's Not What It Looks Like, Kaname says that she knows it isn't and tells Tessa off.
- Girls Bravo has this happen in the first episode - Yukinari gets up and goes into the bathroom, only to accidentally walk in on Kirie when she's naked, so she attacks him. Why is it this trope? Because it's his house and his bathroom, which she has no right to use and didn't even get permission to use. She also expects him to remember that she was gonna come over to use the bathroom again like yesterday. To make things worse, when he explains that it was an accident and how, because of his allergies to girls, he wouldn't even want to see her naked, she attacks him regardless for not wanting to see her naked. Kirie has a tendency in general to overreact to anything she perceives as sexual in nature - heck, the reason he's allergic to girls is because she assaults him so often!
- Gleipnir: A classmate is sitting lewdly on a desk and making her panties visible, but Shuichi Kagaya has his head down and doesn't even notice. The girl still attacks him and calls him a pervert.
- Gonna Be the Twin-Tail!!: Averted with Aika, despite her character archetype. Rather, she always goes for Twoearle, who's usually responsible for the antic Souji ends up in.
- Guilty Crown: Shu's alone in a room wearing only a Modesty Towel in episode 5 after being knocked out by Ayase. Then, Ayase suddenly enters without knocking or anything and shocks Shu into dropping his towel, who gets embarrassed and tries to cover himself. Cue an Oh, Crap! and then a slap from Ayase.
- Heaven's Lost Property has this happen at the start of the first episode; Tomoki's neighbor Sohara comes into his house to wake him up for school, tears off his blanket, and then screams and karate chops him in the face after seeing his morning wood when he was barely even awake.
- High School D×D
- This is one of the very few anime out there that subverts this trope despite high amounts of Fanservice. The shining example would have to be Koneko wanting to make out with Issei and Rias walks in. Issei expected that he was going to get smacked by Rias, but instead Rias just takes a look at Koneko's condition and says that she's sick. The only time Issei even gets beaten is if he actively does anything perverted.
- Sadly played straight in the DVD extras, where an obvious accident involving Marshmallow Hell with Rias and Asia means Koneko gets to smash his head like a watermelon. Then again, the extra was a large Out-of-Character Moment for everyone. (It's implied to be a Dream Sequence for Issei, whose pre-Character Development brain is running on unfiltered Harem Anime tropes.)
- The series actually deconstructs this trope at one point. When Rias starts getting bitter and passive-aggressively shaming Issei when she catches him with another girl, even when they're obviously the ones coming onto him, it's deliberately shown to be irrational (especially since she's been nothing but fair to him up to that point) and hinting at bigger issues.
- Played straight in the fourth season of the anime, where Koneko punches Issei in the gut for saying he didn't like "little girls" (which was a no-win situation for Issei, since he was denying getting friendly with a young kitsune because she had good genes). It actually ties into her characterization in the Light Novel, which is a subversion; Koneko is deeply insecure about being a completely flat member of a harem for someone who openly believes in the Buxom Beauty Standard and tends to lash out when he says something that suggests she's not sexy, she's aware how unfair this is and she's not proud of her behavior.
- Ichika from Infinite Stratos sometimes gets attacked by the girls for things that are clearly not his fault. For example, it's initially thought that he knew that "Charles" was actually "Charlotte" and deliberately kept quiet so he'd have a cute girl for a roommate.
- Inuyasha: The title character gets hit on the head several times after accidentally walking in on Kagome bathing to the point that it's a running gag. Bonus points for the time when Inuyasha and Miroku stumble onto Kagome and Sango bathing in some hot springs and they both get smacked. Inuyasha is pissed, but Miroku, an actual pervert, is pleased with what he got to see.
- Is It Wrong to Try to Pick Up Girls in a Dungeon?: In the final episode of Season 4, Bell and Ryuu are rescued from the Dungeon and sent to the hospital. When Ryuu wakes up, she immediately gets up and looks for Bell. When she finds him, her hospital gown falls apart leaving her naked and embarrassed. Before Bell can even process what is going on, Hestia and Liliruca punch him simultaneously and knock him out. At the very least, the nurse scolds and lectures the two for attacking an injured person.
- Is This A Zombie? In the beginning of one episode, Haruna ends up having a dream where Ayamu is about to have his way with her. Fortunately for her, she wakes up and realizes that it's just that, a dream. Unfortunately, she goes and attacks the real Ayamu for it, while he's still sleeping. Even more unfortunate, the other girls are on Haruna's side, despite the real Ayamu having nothing to do with what Haruna dreamt.
- KonoSuba: Being a Hikkikomori and Otaku, Kazuma is familiar with this trope and hates it. He's warned on several occasions that if something like that ever happened in real life, he'd have no qualms fighting back with equal violence with the argument it's self defense. By the same measure, he's actually okay with being punished if he actually does do something, like the time he tried to peek on Megumin and Darkness in the bath and they retaliated by pelting him with bathing implements. His only complaint was that poor Chomusuke happened to be in a basin they tossed at him.
- Love Hina is (in)famous for this trope.
- In one chapter, Naru punches Keitaro when he walks in on her changing. Later in the same chapter, she walks in on him changing, and he's still the one who gets punched.
- One time, she tries to hit Keitaro on the grounds that he must be thinking something perverted.
- Another time, Tama-chan the turtle has gone missing, and Naru and Keitaro are looking for it. Shinobu has just got home and is changing her clothes when she is scared by Tama-chan and comes running up to them clad only in her camisole, grabbing Keitaro in panic. He's too busy trying not to choke to notice her, yet Naru still hits him "just in case".
- Thankfully averted in Magikano, where whenever Ayumi gets close to Haruo, Maika pretty much gives her a piece of her mind. This is a slapstick-based kind of series, after all.
- During episode 2 of Majikoi! Love Me Seriously!, the five girls are lounging in the bath, and catch sight of a dog they were hired to catch. They proceed to chase after it, all five of them butt naked, and eventually come crashing into Yamato's room. Yamato, who was minding his own business, is beaten to a pulp for just being there. Even worse considering one of them is Miyako, who is a pervert and a tease, so she has no business doing something like this, more so since earlier in that very same episode she was thinking out loud to herself that if Yamato wanted to see her naked body, that she would gladly show it to him.
- Maken-ki!:
- In the second episode, Inaho climbs into Takeru's bunk after he's fallen asleep. Yet, the following morning, Haruko slapped him for it, rather than chastise Inaho, since Takeru's perverted antics is Haruko's Berserk Button.
- About midway in episode 3, Takeru and Kengo are chased by a bear during the Maken-Ki's visit to a hot spring. The bear quickly catches up and swats them into the girls' side of the bath, where Himegami and Azuki respond by intercepting them in mid-air with a kick that knocks them right back into the bear's path!
- The manga version differs by having them actually run into the girls' side of the hot spring, to hide from the bear, where they end up fondling Himegami and Haruko's breasts.
Making the girls' subsequent reaction completely justified.
- Mayo Chiki! ends up running into this by default, as main guy Kinjirou has gynophobia or fear of GIRLS, yet other characters are quick to forget this. Even then, there's one instance that stands out: the very naughty, perverted and dominant Kanade is on top of the table and leaning on top of a sitting down Kinjirou, trying to kiss him as he tries to avoid her lips, when her female Battle Butler Subaru walks into the room and yells at Kinjirou "What are you doing at Mistress Kanade?", even though it was impossible to think anything but that Kanade was the one being a pervert here, as it was extremely obvious! And yes, Subaru is fully aware of Kanade being pervy and Kinjirou scared of women, so it seems someone slipped one Idiot Ball into her pocket before that scene. Or twelve.
- M×0: The hero Kuzumi manages to avert this. His chivalrous, life-saving actions and good behavior save him twice in otherwise compromising situations.
- When he falls into the girls' shower after a class match, he did so because some guys in his class took a magic camera-ball and were trying to spy on the girls. He was just trying to get rid of it by removing it from the window and fell through.
- Later, during summer break, he disguised himself as a girl to get into the pool where the girls were hanging out. He ended up saving several of their lives from a giant whirlpool two had accidentally created. The girls accepted him being there just to watch and help them. Though, he was turned into an errand boy for them for the rest of the day.
- My Monster Secret has a deliberate example in the Animated Adaptation. Through a complicated series of events, protagonist Asahi is mistaken for a pervert when he was actually trying to protect his classmate Nagisa Aizawa's secret. In order to sell the act, he asks Aizawa to beat him up and tell the people chasing him that she "punished" him for his actions. Aizawa goes along with it because there's no other choice, but she feels incredibly guilty for doing so and tries to make up for it by telling their classmate Youko (for whom Asahi has feelings) what really happened so she won't think less of him.
- In Neon Genesis Evangelion, Asuka makes her debut by slapping Shinji, Kensuke, and Touji for the crime of seeing the wind blow her dress up. Touji immediately gets revenge by flashing her... and gets slapped again.
- In Rebuild of Evangelion, she instead kicks Shinji in the face for the crime of seeing her naked when she freaks out after seeing Pen Pen and runs into the living room nude. The very next day, she does the same to another boy for simply trying to talk to her in homeroom.
- Kalifa in One Piece takes this concept to its logical extreme: As a Running Gag, she accuses her boss Spandam of sexual harassment from things that are not even remotely related to it, such as talking to her. At one point, she calls him out on sexual harassment for just standing there, doing absolutely nothing at all.Kalifa: Sir?
Spandam: Yes?
Kalifa: That's sexual harassment.
Spandam: My existence is?!- In the Punk Hazard arc, Nami and Sanji switch bodies. After finally getting her body back, Nami quickly realizes she's not wearing the same jacket as before. She clobbers Sanji, assuming he took another opportunity to ogle at her body while they were apart. While Sanji had certainly given her precedent to think so, he actually discarded the jacket while trying to rescue Kin'emon's torso from underwater; clothing created from Kin'emon's power disappears upon removal.
- Averted in Rosario + Vampire, which actually has the girls hit each other simply to get to closer to Tsukune.
- Tsukune lampshades it when on a date with Inner Moka saying he feels he might get hurt if he touches her (she asked to hold hands). As soon as he does, the rest of his Unwanted Harem attack him and Moka.
Inner Moka: "What's wrong? You don't want to hold my hand?"
Tsukune: "I do, but I'm afraid I might get kicked or something like that." - Satirized in The Sacred Blacksmith:Luke: You're sorry? You have a wardrobe malfunction and beat the crap out of me, and you expect sorry is gonna cut it?
- In the Onsen Episode of Samurai Harem: Asu no Yoichi, Chihaya jokingly tells main guy Yoichi he should bathe with her and her sisters. Everyone (That is, Yoichi and the sisters) stare in disbelief for a second before Tsundere Ibuki hits... Yoichi, on the basis he might have been thinking something perverted, even though he was just as shocked as the girls were. And Chihaya, who actually said the perverted comment? Nothing happens to her, not even a "Don't say those things, you might give him ideas!" or something.
- Subverted in Sayonara, Zetsubou-Sensei, when Itoshiki goes to a hot spring, only to realize that his female students are on the girls' side. When Maria accidentally knocks over the divider, the girls don't really care all that much, while Itoshiki covers himself, turns around and lets out a girlish shriek.
- Surprisingly averted in SHUFFLE! ep 7: Due to a broken lock, Rin walks on Asa while she's in the toilet. They both apologize to each other and agree to forget about the incident. No violence whatsoever.
- At one point in the Starship Troopers OVA, Rico encounters Carmen on the Moon and, following the example of a training mate who got a nude pic from his girlfriend, asks her for a picture, making sure to not mention the "nude" part. Before she can answer, the training mate arrives and, not noticing her, asks Rico if he got that nude pic, resulting in Carmen slapping Rico.
- Student Council's Discretion ends up falling into this, as Ken acts extremely perverted and deserving of the payback. However, he soon shows himself to be a much nicer and more caring person than he first appears, and even though the girls know this, he's constantly receiving a lot of abuse. One egregious example comes from the episode where he has to take care of the Wise Beyond Their Years little sister of the newspaper club president. She pulls out some dolls and starts playing with them, but gives them a rather perverted story. She then tells him to join in, which he reluctantly does. As soon he says ONE line, the girls jump in and start lynching him and saying he's a bad influence on the little sister, even though they were around the whole time. This case was an Invocation, as the little girl was intentionally probing at their jealousy: The girls are all attracted to him to some extent, but can't actually admit it and thus blame him. Of course, this doesn't stop the girls from looking like they have a personal vendetta against Ken and are looking for excuses to berate him since nobody normal would have blamed him for this, invoked or not.
- Sword Art Online: Kirito has memorized a number of placating lines just in case he ever finds himself in a compromising situation. When he accidentally gropes Asuna (she was running and crashed into him), he promptly forgot all of them, and she throws him into a wall.
- To Love Ru: Yami absolutely hates perversion, and constantly beats up Rito for it no matter the circumstances. One extreme example is when Yami gets groped and gets pissed at Rito for it. Rito desperately points out that he was standing really far away from her, then Oshizu reveals that the grope came from her out of control telekinesis. Yami still attacks him.
- The Unpopular Mangaka and the Helpful Onryo-san: In Chapter 23, Onryo-san wakes up to find Senai next to her (in his bed), and punches him.
- Vandread does this once with the main character bumping into a girl and then getting a slap for being a pervert.
- There is the slight matter of this being a case of Men and Women are warring SPECIES and (In general...) each thinks the other is going to do horrible horrible things to them at the slightest provocation.
- In The World God Only Knows, Keima is helping Haqua make an After-Action Report with a supernatural simulation device that uses dolls to represent people. Annoyed with Keima, Haqua tells the simulation that Keima is a pervert. When, in response, doll-Keima starts molesting doll-Haqua, Haqua starts beating up the real Keima.
