People not thinking things through in anime and manga.
- The Baseball Episode of The 100 Girlfriends Who Really, Really, Really, Really, Really Love You happens because the school's entire girls' baseball club sans Iku Sutou left for America to study baseball for an upcoming championship that will decide the fate of the club... less than a week before the championship begins!
- In Akudama Drive, while convincing the Akudama that she is a legendary Swindler managed to get them to spare the main character's life, it also gets her wound up deeper into their schemes since they consider her part of the gang. They even convinced the police that she managed to swipe her name off the records as part of her shtick before she could explain her situation, further reducing her chances of seeking their help to escape.
- During the second-year barbecue in the thirty-third chapter of Asteroid in Love, Mira tries out a homemade baumkuchen recipe she read. What she doesn't realize is, the nature of baumkuchen means she needs to grill dozens of layers of cake on a spit, making the process more tedious that she thought.note
- In Attack on Titan, the country of Marley were the cause of many of their own problems.
- They harassed the Eldians of Paradis by dumping Titans on the island for a century... meaning that as of the present, it's not safe for them to enter the island and exploit its rich natural resources. Hence, their desperate search for the Coordinate, which would allow them to neutralize the problem they themselves caused.
- Their attempt to gain the Coordinate was quite slapdash, since no normal soldiers would survive on the island and any info they had was 100 years out of date. The four Titan Shifters they sent were Child Soldiers indoctrinated to fight for Marley, but since they were kids and not emotionally prepared for combat and being spies, they end up completely blowing the plan by making rookie mistakes, along with Reiner going insane under the pressure. Not to mention, sending 2/3 of their Titan Shifters to Paradis meant risking them against the one nation in the entire world that had a century to perfect specialized warfare against Titans (not to mention they had a Titan Shifter of their own, but nobody knew that). This leads to...
- They've been making heavy use of the Titans for warfare, but in the aftermath of the horrible mess that was the above plan, they lost access to two Titan Powers and gained a new enemy in the Paradis Eldians, who also now have two Titan Shifters of their own. This embarrassing failure has also emboldened the other nations, who are now taking the opportunity to get some payback.
- Banished from the Hero's Party: Ares' decision to kick Gideon out of the party proves to be a terrible idea on multiple fronts:
- While Gideon's combat skills may have fallen behind the rest of the Party, his non-combat skills such as cooking, medicine, logistics, and negotiation, as well as his position as The Heart of the Party, are all sorely missed after his departure, causing their morale to quickly plummet. As a result, the Party's resentment of Ares soon turns into outright hatred of him.
- Gideon also served as The Strategist of the team, with his keen insight, ability to discern opponents' Blessings, and knowledge of monsters and their strengths and weaknesses often being the key to the party steamrolling their way to victory after victory. Once bereft of his intellect, the Party's tactics quickly devolve into simply bashing their enemies until they die, which would have likely failed but for Ruti's monstrous strength and endurance, and monsters they otherwise would have easily picked apart have become major obstacles.
- One of the main reasons Ares wanted Gideon out of the party was so he could take his place as Ruti's confidant and second-in-command, with the goal of romancing and eventually marrying her as part of his agenda of climbing up the ranks of nobility. Not once did it occur to him that Ruti would rightfully blame him for driving her beloved brother away, to the point where she tells Ares in no uncertain terms how much she hates him for it and would have gladly killed him if her Blessing didn't prevent her from killing anyone who's not a direct threat to her life.
- He also assumed the rest of the party hated Gideon as much as he did, as they were always critical of Gideon's fighting ability, and that they would thank him for getting rid of the "dead weight". Instead, with the party sorely missing his mental and social skills, Yarandrala immediately quit in outrage, Danan left to bring Gideon back to the party, and Theodora would have followed suit but for Danan asking her to stay by Ruti's side so she'd have at least one trustworthy person watching her back.
- Ares never realized (or more likely, refused to acknowledge) that Gideon went out of his way to watch his back during large battles, keeping him covered while he cast his spells. After Gideon's departure, Ares is nearly killed by a monster during a Dungeon Crawl, and Ruti lets him know she has no intention of protecting the man who drove away her beloved brother.
- Bleach: After his Heel Realization from fighting Ichigo, it has been revealed that Renji had been trying to surpass Byakuya ever since Rukia had been adopted by the man. To do this, he focuses on getting his Bankai, which increases the power of one's Zanpakuto tenfold. Upon getting it, he immediately charges off to Byakuya, confident in his victory...not realizing that as a captain, Byakuya has a Bankai as well, which he's trained with for decades as opposed to Renji getting it that very day. Renji has just enough time to realize this before getting shredded.
- In Bokurano, Junji "Katari" Karita decides to pretend to be a Zearth pilot in order to delay or prevent his parents' divorce. In order to "prove" this, he plans on doing a victory dance at the end of the next battle, even though he can't control the robot. Ushiro and Machi lampshade this, noting that he must have assumed the actual pilots would have played along.
- Harumi Kiyama in A Certain Scientific Railgun plays this both ways. On the one hand, she's the only villain who realizes the damage her plot is causing, and actually creates a way to reverse the effects harmlessly once she's finished. On the other hand, she failed to account for what would happen if people randomly fall into a coma — such as if they're driving a car.
- Citrus: While her intentions were pure and her motives noble, Yuzu clearly didn't consider the ramifications of blurting out over a microphone in front of everyone, including her grandfather-in-law, the chairman of the school, during assembly to everyone that she saw Amemiya, one of the school's teachers, kissing Mei. Said incident caused Mei's grandfather to remove her from Yuzu's mother's care and place [Mei] back under his own.
- In Delicious in Dungeon, Team Touden decide to use Senshi's adamant cooking pot as a shield against the Red Dragon's fire...forgetting the main reason Senshi converted his ancestral shield into said pot is because one of its properties is spreading heat fast and evenly. Cue Laios dropping the pot in pain after the first blast of fire burns his hands.
- In a dubbed episode of Digimon Adventure 02 ("Cody Takes a Stand"), the trope is humorously activated when Cody attempts to stop BlackWarGreymon (one of the season's strongest villains) from destroying a Destiny Stone.Cody: Don't take another step or else!
Blackwargreymon: Or else what?
Cody: Um...I haven't figured that part out yet. - Don't Toy with Me, Miss Nagatoro: Naoto (Senpai) attempts to call out Nagatoro's friends for their "harsher than expected" teasing, only to sit back down and continue eating. When asked why he stopped midsentence (apparently leaving them in suspense), he states that he didn't think that far ahead in what he was going to say.
- Dr. STONE: The Kingdom of Science spend an entire year building a telephone to communicate with Taijuu and Yuzuriha who are spying on the Empire of Might. When it's finally time to test the newly-build phone, Kohaku then asks how they are gonna communicate with a single phone. With this realization, Senku announces they're gonna have to build another, which he forgot.
- Dragon Ball has a TON of examples of fighters not thinking their strategy through. If they have done so, then half of the plots would be resolved much quicker:
- Vegeta tends to be a victim of it more than anyone thanks to underestimating the power of his opponents:
- He gets this during the Saiyan battle after Gohan turned into a Oozaru. Escaping being crushed multiple times, he did seem proud of himself for a moment after cutting off the boy's tail, thus shrinking him to normal size. Given that, while Vegeta has taken a considerable beating fighting the various heroes, Gohan was the last one strong enough to present any kind of threat to him, it seems that he's won. Then comes the brief realization that Gohan is still semi-gigantic, not maintaining his place in the air and now falling towards him while semi-gigantic. Since he wasted the last of his remaining power in the blast he used to cut Gohan's tail, he's unable to dodge. Not long after a crushed Vegeta is sitting in a crater, struggling to crawl to his ship.
- Vegeta gets another moment after he forces Dende to heal him to give him a power boost to fight Frieza. Not once did he take into account that Dende would refuse to help him since Vegeta slaughtered an entire village's worth of innocent Namekians earlier in a search for the Dragon Balls, and leave him to die. Piccolo talks him into doing so, only because they need Vegeta to even stand a sliver of a chance against Frieza. Even worse, Frieza notices Dende healing Vegeta, which only provokes more headaches to the heroes, as the first thing Frieza do as soon as he end his transformation is kill Dende.
- After Dende heals him, he starts fighting Frieza himself, only to severely underestimate Frieza's power in his final form. His training in the Hyperbolic Time Chamber boosts his power enough to defeat Semi Perfect Cell, but then he helps Cell attain his Perfect form and gets beaten half to death for it. He also plans to take advantage of Babidi's brainwashing to increase his power to fight Goku only for the energy released to repower Majin Buu. Even his attempt to sacrifice himself to destroy Buu fails because he severely underestimates the creature's regenerative abilities.
- Goku himself falls into this during his plan to pit Gohan against Perfect Cell; while Gohan is the strongest of them all, Goku failed to consider that Gohan is half-human, doesn't have the same love of fighting as his father, and above all else, is Just a Kid. It's only when Piccolo points this out to him that Goku realizes how badly he may have screwed up.
- Cell himself is subject to this in his eponymous saga; his goal is ultimately to force Gohan to awaken his hidden powers by forcing him to watch as his friends get beaten up and a pacifist android is killed right in front of his eyes. Cell eventually gets exactly what he wanted all along, but he never stopped to consider the possibility that he might actually lose.
- This is a key reason why Gohan's warning to Cell about his hidden power backfired; Gohan failed to consider that Cell, being a big-time Blood Knight, is the kind of person who wants him at full power for the sake of a good and challenging fight.
- Babidi does this thrice. First, he tries to keep Piccolo from killing him by pointing out without someone to seal Majin Buu away, he'll destroy the world. Piccolo points out that's what Babidi intends to do anyway, so the end result would be no different and bisects him. Then he has to get Buu to heal him, and later tries to get him to fight Goku under the threat of being sealed away, which Buu points out would leave Babidi without Buu's protection, and then Goku would kill him (luckily for him, Buu's willing to fight Goku anyway). His luck runs out on the third go; he's been abusing Buu and ordering him around under the threat of being re-sealed, but Buu is much faster and stronger than him, and once he finds away to prevent Babidi from using the spell (strangling him — he can't recite the incantation if he can't speak), Babidi does not last long.
- On a fundamental level, Babidi's greatest error was to try and use fear to control Buu: Bibidi had been able to more or less keep control of the massively more powerful Buu by bribing him with cakes (and it's implied he managed to do with Kid Buu, who was otherwise impossible to reason with), but the moment Babidi threatened to seal Buu away he immediately decided to try and murder him and started taking actions that had a great chance to "accidentally" kill him, at least until he figured out how to keep him from using the sealing spell.
- There's also the fact that Babidi continually let his minions die, and they could have helped save him from Buu in his final moments.
- During the Tournament of Power, Belmod has Jiren go after Goku with the explicit intention of showing off his immense power and scaring everyone into submission, as Jiren would often do against his foes to force them to choose between surrender and annihilation. Jiren does his thing, shows off his immense power and that he's the mightiest warrior of all... Except the penalty of a team losing in the Tournament of Power is annihilation, for them, their whole universe, and their very souls, so while Belmod and his Kaioshin counterpart bluster about Jiren's strength, they're quite surprised when the aces of the remaining universes start assembling to just gang up on him.
- Piccolo is one of the smartest characters in the franchise, but he has this as a Fatal Flaw. All of his battle plans fail due to being poorly thought out, and Goku of all people repeatedly and effortlessly outsmarts him:
- His first fight with Goku at the 23rd World Tournament is basically just one long series of Piccolo doing something stupid, Goku telling him exactly why he's an idiot, and Goku then repeatedly punching him in the face. His blunders include nailing himself with his own guided beam, wasting all his energy on an extremely inefficient omnidirectional attack that doesn't faze Goku at all (really messes up the island, though), and turning into a giant after Goku taunts him, which allows Goku to smack him around and free Kami from his stomach. Despite possessing Power Levels equal to Goku's, he only ever had a chance through one cheap shot that only happened because Goku insisted on tournament rules long after Piccolo had disregarded them.
- When he first meets Raditz, he somehow forgets to sense his opponent's ki. As a result he arrogantly talks down to someone way stronger than him and then attacks him, only for Raditz to pull a No-Sell. He's extremely lucky that Raditz deemed him Not Worth Killing. Later, during their fight with Raditz, Piccolo's plan of firing his Special Beam Cannon with Goku as a distraction completely neglects actually immobilizing Raditz, so the first time he fires it, Raditz just easily leaps out of the way. When Goku independently comes up with the idea to put him in a full-nelson after Gohan lands a good sneak attack on him, Piccolo just looks confused until Goku yells at him to hurry up and charge another beam.
- When Nappa plants the Saibamen, Piccolo gets angry with the Saiyans for wasting his time and decides to wipe them all out instantly. It takes Krillin pointing out that the whole reason they're there is to stall for time to get him to back down. Had he actually gotten his wish everyone would have died long before Goku got there.
- His first plan to take down Nappa requires Gohan to unleash his full power at one decisive moment, even though Gohan has never been able to do that at will at this point and is a child without any battle instincts. It doesn't work. Piccolo himself later states he was stupid for thinking it would. His second plan involves trying to grab Nappa's tail, even though Goku outright told him during the fight with Raditz that a Saiyan could detach their tail if they needed to, and that he himself (despite having much less battle experience than Nappa) trained his tail to not be a weakness when he was only a child. Piccolo still puts all of his stock in the tail plan, grabs Nappa's tail... only for Nappa to laugh at him for thinking that would work and knock him out with an elbow to the cranium.
- He demands that Gohan wish him to Namek, despite Krillin's objections (since if Piccolo died the Dragon Balls would turn into stone and the whole trip would be pointless), because he thinks two weeks of training on King Kai's world have made him strong enough to defeat Freeza. When he gets there and senses Freeza's ki, he immediately realizes that no, it didn't, and wonders why he thought that it would. He's damn lucky that Nail just so happened to be near where he spawned to offer a convenient power-up, or else Piccolo would have ruined everything right there.
- He agrees with Vegeta that they should let Gero create his androids instead of killing him because his Blood Knight pride requires he fight them (Goku at least had the "justification" that Gero hadn't done anything wrong yet). Despite Trunks (who is way stronger than Piccolo) explicitly telling Piccolo that these androids would massacre them.
- He toys excessively in his fight with Dr. Gero, allowing him to escape despite Piccolo's drastic power advantage. It gets to the point that Vegeta, no stranger to toying and boasting himself, gets sick of it and just tells Piccolo to finish him off before he pulls out a trick.
- Even after merging with Kami, he has his moments. For example, after a fairly clever Wounded Gazelle Gambit to get Cell to exposit his backstory, Piccolo immediately blows his cover, credits the plan to Kami, and screws it all up to brag. In the process he teaches Cell about his regeneration and gives him a chance to escape.
- Later, he decides to fight Android 17, hoping to destroy either him or Android 18 to prevent Cell from absorbing them to power up. A good plan... except Piccolo forgot to take into account that Cell can sense Ki. The sudden rise in Piccolo's Power Level immediately tips Cell off that he's fighting the Androids, since no one else would make him fight so hard; rather than prevent Cell from finding Androids 17 and 18, Piccolo ends up leading him right to them.
- While Goten and Trunks are training in the Hyperbolic Time Chamber, Piccolo asks Super Buu to go and kill some more humans to buy some more time. Buu agrees... and wipes out the human race with one coordinated barrage of Ki blasts rather than just hunt down a few of them.
- Throughout the manga-exclusive Galactic Patrol Prisoner arc, Piccolo's competency has taken a sharp, noticeable downturn as he repeatedly makes amateurish mistakes. He spares the Macereni Gang after falling for their obvious Wounded Gazelle Gambit and failing to adequately press his suspicions that their arrival on Earth might have something to do with the conflict he sensed in space, a mistake that endangers Earth by drawing Moro's more powerful henchmen to the planet. If Piccolo had remembered his telepathy, none of this would have happened. Later, he gets distracted and leaves himself open to Seventhree's power copying ability that Jaco had warned him about seconds prior, something that even Piccolo admits is sloppy. When even Jaco is calling you out on your blunders, you know you done goofed.
- King Kai makes this sort of blunder in the Saiyan arc; While training Goku for his fight against Vegeta and Nappa, King Kai realizes on the day before the Saiyans arrive on Earth that he forgot to take into account that Goku would have to travel back down the Snake Way before returning to the living world. Luckily, Goku's improved speed meant he would only be a day late...which was enough time for Nappa to mercilessly kill the other Z-fighters except for Krillin and Gohan.
- Vegeta tends to be a victim of it more than anyone thanks to underestimating the power of his opponents:
- In Dragon Quest: The Adventure of Dai, when Dai, Pop, Maam, and Baduck need to go from the island Matoriv is on to the one Flazzard occupies in order to rescue Leona, Matoriv gets them in his own personal boat before sending it flying across the ocean filled with whirlpools using his magic. It does what Matoriv intends, but, as Dai points out while the boat is still flying, the boat can't stop. Cue everyone on the boat panicking as it's closing in on a rocky terrain.note
- Engage Kiss: Shu Ogata makes a deal with the demoness Kisara so that she will assist him in battle and help him find out what happened to his family, and in exchange, he has to regularly sacrifice random memories to feed and power her up. However, losing his memories makes him more and of an Empty Shell, he forgets about his past girlfriends who become really upset when he doesn't recognize them, and some people point out he has no plan for if he eventually forgets about his family. Eventually, Kisara, who had fallen in love with him, refuses to take any more of his memories when she sees what is happening to his personality.
- Failure Frame: [Heroic Sword] beat up Nyaki so hard they nearly kill her. It never once occurs to them that doing so would anger Vicius.
- Falling in Love With the Villainess:
- Queen Sophia decides that having her handmaiden smuggle Rion into the slums and then lying to the king about her child's gender so that any rescue attempts would almost certainly fail is a good idea. To say it isn't would be an understatement, although to be fair she had no way of knowing just how badly Rion would suffer in the slums.
- Captain Frederic offers Rion a chance of becoming the Royal Guard to Prince Arnold. It has to be spelled out to him that Rion working for the guy who drew blades on him no less than three times and is directly responsible for the death of one of the few people Rion cares about is likely to result in the prince's death.
- Prime Minister Saed gets it into his head that forcefully dissolving the marriage between Ariel and Rion and scheduling an Arranged Marriage with Maria is a good idea. Prince Arnold, of all people, has to point out that such a hair-brained scheme would easily trigger a very, very bloody civil war.
- Fate/kaleid liner PRISMA☆ILLYA: Darius Ainsworth surrounds the entire battlefield with a massive dome of ice, then gloats to the heroes that the dome is airtight, so they will soon suffocate. Shortly afterwards, he realizes that since he is inside the dome, he is suffocating as well. Fortunately, Tanaka was able to melt through the ice.
- The Remnants of Sephiroth in Final Fantasy VII: Advent Children are looking for Jenova. After attacking Edge City, fighting Cloud, his friends, Rufus Shinra and the Turks, Kadaj finally gets her head... and has no idea what to do. Cloud lampshades it stating that as a fragment of Sephiroth he's acting on instinct rather than thought.
- Fullmetal Alchemist: Shou Tucker infamously uses alchemy to fuse his own five-year-old daughter with her dog, transmuting an abomination in constant pain in his desperate attempt to keep his State Alchemist certification, since he'd gotten a warning that his results were inadequate in his previous yearly evaluation (his first since becoming a State Alchemist). After doing this, he decides that it's a good idea to show off "a chimera that understands human speech" to the Elric brothers... except that he somehow didn't take into account the fact that a talking chimera can, well, talk and potentially expose his dark secret to his guests who had developed a close friendship with Nina while she was human — which is exactly what happens, and it leads to Tucker's house-arrest, revoking of his State Alchemist certification, and death at the hands of Scar who had heard of his crimes. It doesn't help that this is only a short-term solution, and even if Tucker could come up with an explanation for his daughter's disappearance, he'd be out of family members to use in his experiments by the next time he has to go in for evaluation.
- The first episode of Gate starts with an other-worldly army comprised of Medieval tech that enters the modern-day Ginza District of Tokyo, Japan through the titular "Gate" itself, while obviously succeeding at first as it's nothing more than poor civilian targets along with mild Police combatants, after showing nothing but brutal slaughter as their "First Contact" solution to the people of Japan, the JSDF shortly preps up a retaliatory force that completely annihilates the invading forces and then proceeds to make a Forward Operating Base on the other side of the Gate so that the event never happens again. The main medieval force promptly suffers the same defeat its "scouting force" did, and it just gets better from there in showing the "Empire" new ways of utter humility. Several critics of the Empire like King Duran call them out for trying to invade an unknown land without assessing its strength first.
- In Girlfriend, Girlfriend, during the Hot Springs visit, Nagisa tries to hide her relationship with Naoya by claiming to be rooming with Mirika, who followed them there. When Naoya abruptly shows up while she's bathing with Mirika, she's adamant about not risking the relationship getting outed to Shiho, so she blocks his face with her towel, rushes into the room, and gets changed before leaving. However, she seemingly forgets that Mirika is her roommate and they were both using the bath when Naoya showed up.
- A lot of Rika's plans end up this way, but she manages to make them work by sheer determination.
- In Girls und Panzer, the Oarai student council revives its Tankery program in order to compete in a national tournament which is a lie to cover up the fact that the school will be shut down, but they have made a deal to prevent that if they win. Unfortunately, the student council overestimated how many tanks they had left over, i.e., the ones they weren't able to sell, assuming that the school would have many in reserve from its past participation in tankery. Student Council President Anzu admits that her assumptions were faulty, but she couldn't think of any other way to keep the school open, and at least wanted them to have hope.
- In Gourmet Girl Graffiti, Akira, Ryou's aunt, attempts to surprise her in episode 12 by grabbing her arm as she opens the door to her apartment. However, Ryou is understandably shocked and scared, so her first instinct is to slam the door in the face of the person grabbing her arm. Akira apologizes and sports a bandage on her face in the next scene.
- In The Great Jahy Will Not Be Defeated!, Jahy sets up traps in her apartment for the magical girl and doesn't stop to think how she's going to get out if the magical girl doesn't show up, leaving her stuck in her apartment until Ryou shows up to ask for the rent.
- Gundam:
- In Mobile Suit Gundam ZZ, Judau needs help so Iino decides to join him in the Zeta Gundam. However, the Zeta lost its head during the fight with the Hamma-Hamma, so Iino attaches a Zaku II head onto the Zeta and launches in the "Zeta-Zaku". To Iino's horror, he realizes that the Zaku II's head, being nearly 10 years out of date, has poor visibility due to it being built long before the advent of the 360 degree Panoramic Cockpit.
- A one-episode villain team in the same anime came up with a tactic to blind the enemy with a smokescreen so they couldn't fight effectively. Only after they created the smokescreen did they realize that they didn't have a way of tracking their enemies through the smokescreen either.
- In Gundam Build Divers episode 19, Rose of team Hyakki falls into this trope repeatedly. At the first checkpoint of the Nadeshiko-athlon, when asked to build a Gunpla to complete the checkpoint, she chooses a Master Grade Sazabi Ver. Ka., noted for its complexity, because it's one of her favorites and always wanted one. Emilia of team Avalon nearly falls for it as well with choosing the Master Grade G-Armor, but opts for the much faster Haropla build, which all the other racers choose. At the third checkpoint, Rose chooses a Neue Ziel to go up against Emilia's AGE-1 Titus. However, her match is a Puppet Sumo fight and because her Gunpla has no legs, large shoulders and a massive binder tail, her Gunpla falls over, allowing everyone to beat her. The final choice has her deciding that the wrecked vehicles meant that everyone should use their Gunpla to win the race, which ends up nearly disqualifying everyone.
- In Mobile Suit Gundam: The Witch from Mercury, this is Miorine's Fatal Flaw. The girl can plan stuff out if she has context and an idea of what to do, but if she does something completely on the fly, it leaves her flatfooted and easy to manipulate. Prospera expertly uses this on Miorine during the second half of the series by using her desire to stop Prospera from using Suletta as a pawn to systematically destroy her, ending her engagement with Suletta, forcing her into a loveless one with Guel, destroying her goodwill with the Earthians and leaving her with a company on the verge of being dismantled.
- In Mobile Suit Gundam SEED Freedom, Shinn tries to get in between a fistfight between Kira and Athrun. They both end up socking him in the face and dropping him.
- Hirogaru Sky! Pretty Cure has one that mocks the franchise's habit of tearful farewells and a Time Skip. Sora, Tsubasa and Ellee say their goodbyes to Mashiro and Ageha in a heartfelt and heartwrenching farewell. The very next day, as Mashiro wonders what the others are doing, a portal opens up and there they are. Tsubasa admits that it's kind of embarrassing to have went through all of that and then just suddenly return.
- Hunter × Hunter: In a fit of desperation, Cheetu creates a crossbow-claw weapon to fight Morel for both close combat and long-range attacks. Morel then asks why he would want a power that's slower than he is, leaving Cheetu completely speechless.
- Inuyasha:
- The ogre witch Urasue steals Kikyo's remains and brings her Back from the Dead in a clay body, planning to use the resurrected Kikyo as a slave to gather the Shikon Jewel shards. Instead, the very first thing Kikyo does upon revival is use her spiritual powers to blow Urasue up; Urasue obviously never considered the possibility that the resurrected Kikyo would turn on her, let alone immediately after her resurrection.
- Inuyasha and Sesshomaru's late father, Toga, played the Long Game when it came to his sons' inheritance. While he was obviously hoping that Sesshomaru would take on a Big Brother Mentor role towards his younger half-brother, it backfired when Sesshomaru instead saw being left Tenseiga while Inuyasha was left with Tessaiga as Parental Favoritism on his father's part; it steps up his dislike of his half-brother to actual hate, and he tries to kill Inuyasha several times. It's likely that this would have worked had Toga lived to be able to guide Sesshomaru personally, but without him there was no one up to the task.
- Is It Wrong to Try to Pick Up Girls in a Dungeon?: Bell Cranel enters the dungeon to follow his adoptive grandfather's advice to save a girl in danger to get a Rescue Romance going. It never occurred to him that the only girls who enter the dungeon are trained warriors who don't need saving. Plus, he entered the deeper levels of the dungeon after only two weeks of training, so if Ais Wallenstein hadn't stepped in, he would have gotten himself killed.
- Is the Order a Rabbit?:
- In episode 3, with it raining harder and harder, Rize says she'll call for a cab to take Sharo home. Chiya, remembering Sharo exclaiming she didn't want Rize to know where she lives, instead volunteers to take her. However, she attempts to carry her home, and collapses a short distance from the Rabbit House.
- In episode 7, the girls work on a large jigsaw puzzle. As they get closer to finishing it, Chiya asks where they're going to place it. The girls are then stumped because they didn't consider what to do with it when they were done. In the end they have Chino's father put it up in the coffee shop to replace another picture of a rabbit.
- JoJo's Bizarre Adventure:
- In JoJo's Bizarre Adventure: Stardust Crusaders, the villainous cowboy Hol Horse tries to use his Stand, Emperor (which looks like a revolver and shoots auto-tracking bullets), as a Weapon for Intimidation to threaten some workers into doing what he wants. Unfortunately for him, Stands are Invisible to Normals (only another Stand user would be able to see Emperor), so all Hol Horse does is make a fool of himself, at which his unwilling partner Boingo reminds him of the previous fact.
- In Jo Jos Bizarre Adventure Steel Ball Run, there's a mention early on of a German baron who's looking to participate in the title event, a cross-country horse race, driving an automobile, which Stephen Steel authorizes in the name of innovation. In chapter 6, he realizes why this was a terrible idea when his car runs out of fuel almost immediately.
- Kaguya-sama: Love Is War:
- Ishigami joined the cheer team to improve his demeanor, on the grounds that people on the cheer team always seem happy. It was only after he showed up at the first meeting that he realized the flaw in his logic, the only people who join the cheer team are those that are already too happy with their lives. Subverted in that it does give him a more positive outlook, just not in the way he envisioned.
- Chapter 180 has Ishigami telling Iino about a masterful, large scale Batman Gambit that Fujiwara pulled off on their entire grade... that ultimately screwed over Fujiwara herself. Unlike most schools, the funds for the second years' school trip are managed by the student council and they're usually a huge strain on the yearly budget, but proposing a cheaper local destination is bound to be meet with backslash from the student body. Fujiwara proposed the alternative of putting the trip's destination to a vote, knowing that people wanting to travel overseas would be too divided in their preferences for any of them to get a decisive majority, and that out of the three local options — namely Hokkaido, Kyoto, and Okinawa — the cheapest one was likely to win because Hokkaido is too cold in January and this year's sophomores already visited Okinawa in middle school. What Fujiwara didn't consider in her exercise of giving people a false sense of free will through democracy to silence protests before they can even be voiced is that she didn't want to go to plain old Kyoto herself, but she was in a power trip at the time and when she came down from it, the damage was already done. Ishigami both praises and mocks her at the same time by saying Fujiwara is nearly as talented a politician as she thinks she is, but she's also an idiot at heart.
- Kill la Kill: Satsuki's main reason for destroying Nudist Beach's home base was to remove stragglers from her upcoming assault on Ragyo, stating that any group which cannot defeat her Life Fiber-enhanced army would be useless against Ragyo and COVERS. Not only does her rebellion fail in epic proportions, but she later discovers that Nudist Beach had a secondary base on standby, and it plays a major role in Ragyo's downfall.
- In Lupin III: The Italian Adventure, we have a group of four teachers in the episode "High School Undercover!" who commit so many unthinkable contrived answers to their problems regarding their little mishap with a gang leader. In summary they 1) absolutely disregard asking the police to arrest the thieves (even knowing where they'll meet the gang) and instead face possible death if they don't give him money; 2) they build a bomb to retaliate back but for some reason it needs a diamond to work (never mind the fact one of said teachers asked his wife to lend him a diamond ring but didn't think about just taking it from her when she wasn't looking); 3) they try to defend themselves from Lupin himself after the thief tries to retrieve the stolen diamond jewel he lost, but they all arm themselves with a golden bat, a mop (because his wielder would mop the floor with Lupin), a bass instrument (to drop the bass on Lupin), a bottle of sulfuric acid (perhaps the only real weapon but only gets flung across at a long distance and misses Lupin, who doesn't even try to dodge) instead of, again, asking the police for help; and 4) Lupin questions them on the fact they could have simply pawned the rare diamond they got for money instead of building the damn bomb needing one to work. To cap things off, one of the teachers is actually the vice principal of the school, but he's a much bigger mess of a man than the other three. In the end, the police does come to their aid and arrest the gang about to kill them all because Lupin grew soft and decided to give them a hand from the shadows.
- Maria no Danzai:
- Kiritaka's bullies regularly recorded the various tortures they put him through, and either sent them to him or uploaded them on the internet. Somehow it never occurred to them that Kiritaka would gather the evidence that they conveniently handed over to him and that he would save it up in order to turn them all in one day — which he might've done if they hadn't accidentally killed him after going overboard with one of their pranks. No, instead they now have to deal with Kiri's vengeful mother Maria, who upon finding the videos decides to, rather than turn them in, make them suffer for their sins.
- Using her maiden name to infiltrate the school may not have been Maria's brightest move: when her ex-husband Taiichiro is assigned to investigate the dissapearance of her victims and learns that the local School Nurse's last name is Akeboshi, he starts getting suspicious that she might be related to his ex-wife (even though he admits that it's a common surname).
- Monster Musume:
- Kimihito lies to the Bicycle cop about being Papi's host to keep her from getting in trouble for being outside on her own. This immediately backfires when the Bicycle cop asks to see their paper work, which would have gotten them into even more trouble for lying if Ms. Smith hadn't conveniently arrived.
- Lala visits Kimihito alone after he is hospitalized, in order to avoid everyone trying to fit into his hospital room or causing a scene. This is very good thinking, however, it never occurs to her that her own detachable head, and boasts about being the grim reaper might cause a panic, which they do.
- My Monster Secret: In chapter 184, Youko decides to confront Principal Shirayuki over her treatment of the student body, and of Asahi in particular. Youko being Youko, it isn't until after she's angrily stomped into the office that she realizes she has no idea what she should actually say. Fortunately for her, it turns out to be a case of You Were Trying Too Hard, and she manages to skate through the confrontation on pure dumb luck.
- My One-Hit Kill Sister:
- When Asahi is transported to a fantasy world, something he had always dreamed of doing, he immediately tries to become an adventurer and charges into battle without checking if he had gained any strength, fighting skills, or superpowers. He didn't gain any and is nothing but a wimpy geek. If his sister Maya, who did gain powers, hadn't shown up, he would have gotten himself killed.
- Maya followed Asahi to the fantasy world, but had no plan to return them to Earth.
- Naruto:
- Sakura's attempt to kill Sasuke was not successful. Even if she could have poisoned him as planned, Kakashi points out that he was immune to the poison anyways due to his absorption of Orochimaru.
- Madara Uchiha's plan relies on two other people's actions, and would be ruined if either person died or decided to do their own thing. Obito had to carry out most of the plan, but while he was sufficiently convinced to go through with it there was nothing that made him actually personally loyal to Madara's vision for how the plan should go. The seal on Obito's heart prevented him from directly hijacking the plan, but could be removed through being stabbed in the heart, which Obito tricks Kakashi into doing. He also relies on Nagato resurrecting him at the right time, ignoring that last he saw Nagato, he was an orphan in a war-torn country who could end up dead at any time, and again relies on Nagato actually carrying out the revival and not using it to revive other people, which is exactly what he ends up doing. Black Zetsu, who was actually manipulating Madara himself, had to go through a round-about method to get Madara revived Came Back Wrong, and then to properly revive him to get the plan back on track.
- In the epilogue, we see Tenten open the weapon store she had mentioned wanting to. She's promptly miserable because opening a weapon store during an age of peace will mean business isn't exactly booming.
- Almost happens in Negima! Magister Negi Magi. The cast are discussing ways to retrieve Asuna and the Great Grandmaster Key from the Big Bads and get the idea to use Natsumi's artifact (which makes the enemy completely unable to sense your presence) to get close for an ambush. Unfortunately, the Anti-Magic field coming from Asuna would make that plan useless. They almost go with the plan until Ako realizes the flaw. Cue Yue coming up with a workable solution and a Moment of Awesome for everyone involved.
- One Piece:
- As Jinbe says during the Impel Down Arc, the World Government's decision to execute Ace and have their Navy go to war with Whitebeard was extremely thoughtless. Not only would the Navy be Awakening the Sleeping Giant, but even if they did succeed in killing both Whitebeard and Ace, the immediate Evil Power Vacuum would turn the seas into a bloodbath, as islands under Whitebeard's protection would become open targets for hungry pirates. Sure enough, when the Navy wins the Paramount War, that's exactly what happens. To make things worse, the war cuts the Navy's forces down by more than half. Combined with Whitebeard's Dying Moment of Awesome when he declared that "One Piece is real," an entirely new age of piracy began, effectively making the Navy's victory devastating to their own cause.
- During the Paramount War, the heroes expend an extraordinary amount of effort to get Luffy to Ace's execution platform. Only after he gets there does he — and everyone else — remember that Sengoku is standing right next to their goal.
- The "Fake Straw Hat Pirates" set base in Sabaody Archipelago after the Time Skip. Since Monkey D. Luffy has attained more infamy than ever before due to his part in the Paramount War, one guy going by the name "Three Tongued" Demalo Black got the bright idea of posing as Luffy and setting up a crew to pose as the Straw Hat Pirates. Black usually gets his way by relying on Luffy's fame to threaten people and recruit fearsome pirates into his crew. Unfortunately, around the time they were recruiting, the real Straw Hats come back, and it gets steadily worse when they try to recruit a pair of Ax-Crazy pirate captains who intend to kill the Straw Hats for more fame, and then Marines show up with Pacifistas, with a Marine Captain personally knocking out Demalo Black with his axe for trying to talk smack to him while pretending to be Luffy. Because he forgot that when you're one of the most infamous pirates on the planet, lots of actual strong people want to kill you.
- The key factor in Doflamingo's strategy to conquer and then hold onto Dressrosa is also the biggest flaw — Sugar. Her incredibly dangerous Devil Fruit Power can turn anyone she touches into a toy-like automaton, stripping away their free will and erasing them from the memory of anyone who knew them, also making it near-impossible to fight her or even get close to her. This made it easy enough to conquer Dressrosa and keep any would-be dissenters in line, especially with a guy like Trebol as her bodyguard. One problem: if she ever is killed or even knocked out, the No Ontological Inertia trait common to all Devil Fruits would mean all the toys would go back to normal. When this finally happens, every single victim over ten years is cured, simultaneously restoring all the lost memories associated with them. This results in a mass panic throughout Dressrosa, as families reunite, pirates loot, and wild beasts run amuck, causing Doflamingo's hold on the kingdom to crumble almost overnight.
- Hody Jones assumes that once he becomes king of Fish-Man Island, he'll be able to go to the Reverie and slaughter all the members of the world summit. That's only if the World Government accepts his rule — they could just as well send some agent of theirs to utterly destroy Hody and his army and install a local government sympathetic to their causes instead. Even if the World Government accepts, a high-class event such as the Reverie would surely have top-notch security to prevent any potential global incidents. This is of course, ignoring the fact that Hody was about to send 100,000 pill-popping underlings against both the New World and the World Government, when they stood no chance against a single pirate crew.
- Vinsmoke Judge, the leader of the Germa 66, wishes to reclaim the honor of his kingdom which has been reduced to a nomadic fleet of ships only really staffed by his army of clones. However, he is a firm believer of Might Makes Right, and following this doctrine had pretty much led to his kingdom's ruin. Throughout the Whole Cake Island arc, it's shown he does not have the best grasp on making decisions. To wit:
- He makes a deal with Big Mom to have Sanji, his son, marry into her family so as to bolster his forces and thinks that once Sanji does, they can simply hold his chosen bride, Pudding, as a hostage. Judge doesn't take into account that Big Mom could possibly backstab him. Sure enough, the arrangement turns out to be a trap where they plan to kill the entire Germa 66 on the wedding day and steal their clone technology.
- In the past, he had forced a procedure on his wife to wipe the emotions from her then-unborn sons, feeling that them not having emotions would make for more effective fighters. When the Big Mom Pirates spring their trap and are set to kill them, Judge is begging for his life while his sons show him no sympathy, telling him to suck it up.
- Lastly, by allying with a big named pirate, he didn't take into account that one of her guests, specifically "Big News" Morgans, would be the leader of the One Piece world's biggest newspaper who could possibly report of his alliance. After the Straw Hats escape from Big Mom's territory, Morgans reports of what went on at the wedding, including said alliance. The result: The World Government disowning the Germa 66 from their ranks.
- Pokémon: The Series:
- For his eighth Indigo League badge, Ash finds himself facing off against Team Rocket, since the real gym leader (their boss Giovanni) is away on "business", and assigned the trio as his substitutes. Ash fights Jessie on a platform that's rigged to electrocute him whenever his Pokémon take damage during the battle. James also rigged Jessie's own platform to do the same thing; when Jessie demands to know why he did so, James admits he didn't think Ash would actually turn the tables on them. Also counts as Genre Blindness and general stupidity, because Ash beats them all the freakin' time.
- Another moment earlier in the Kanto arc was in "Attack of the Prehistoric Pokemon", where in a fit of desperation Pikachu tries to deal with a dynamite fuse by electrocuting it. The very next scene before the stack detonates shows Pikachu with this trope written very clearly on his face.
- In the special short Gotta Dance!, Meowth invents the Pokébaton, a device that forces any Pokémon listening to its music to dance. Unfortunately, he and his comrade Pokémon are just as susceptible to its powers as any other Pokémon.
- During the Alola League, Faba uses Hypno's Psychic to force Ash into using Meltan. But Meltan can and will eat anything metal, so when Hypno attempts Hypnosis, Meltan bites a chunk of its pendulum off, leaving it open for a Flash Cannon and giving Ash the victory. Even moreso, Faba assumes that Meltan is Ash's weakest fighter, even though Meltan is very rare and an unknown threat.
- This happens a lot during Gym battles and Elite Four and Champion battles, to the point where the opponents should really know better. This includes Crasher Wake sending out Gyarados (a Water/Flying-type) against Pikachu (an Electric type) which leads to the Atrocious Pokémon getting KO'd in two blows (though averted when he sends out Quagsire (a Water/Ground-type) against Turtwig (a Grass-type) thanks to Quagsire knowing Sludge Bomb and Ice Beam which are super-effective against Grass-types)), Candice sending out Snover and Abomasnow (Ice/Grass-types) against Chimchar (a Fire-type) and Malva Mega Evolving her Houndoom during its battle with Alain's Mega Charizard X which gets rid of Mega Houndoom's Flash Fire, allowing Mega Charizard X to KO the Dark/Fire-type with a Blast Burn.
- In The Flame Pokémon-athon!, one of the racers entered an Electrode because of its ball shape meaning that it can move quickly. Unfortunately, Electrode quickly tuns out to be Too Fast to Stop when going downhill and it and its trainer wind up in a hole thanks to Team Rocket and it causes a massive Explosion which takes many racers out of the race. Averted with Pikachu and Squirtle as initally, they're left in the dust and struggle going uphill, they quickly recover to aid Ash and aren't eliminated until towards the end when Jessie's Arbok uses Glare on them.
- Zigzagged in Psychometrer Eiji. Makihara Kazuma is the son of a high ranking government official as well as the older brother of a recurring character. After making some bad investments, he staged a Faked Kidnapping so that he could use the ransom money to recuperate his losses without anyone knowing. This is actually a relatively good idea - unfortunately instead of using a random thug for the scheme, he hired the world's best Professional Killer who wasn’t too happy about being used like that.
- Happens rather often in Ranma ½:
- The backstory of the Japanese Nannichuan: in the land of Musashi a pack of foxes was causing misery to the people, so a monk from China helped the people to get rid of them by creating a spring that turned them into men when they bathed into it. The story ends by pointing out it made things worse, as now the foxes were men (so they could now blend in) and their hearts had not changed one bit.
- Happosai has forgotten his invincible technique Happodaikarin, and, hoping to use it against him, Genma, Soun and Ranma go to recover the scroll that describes it. Hilarity Ensues:
- They find there's now an outdoor female hot spring around the place the scroll was buried, and to get rid of the girls they quickly decide to paint Genma's panda form to make him look like a bear and scare everyone. Genma painted himself white, as white bears are the biggest and scariest of all bears... Much to Ranma and Soun's bemusement, as there's no white bear in the wilderness in Japan. The girls chase them off immediately.
- After much shenanigans they recover the scroll, only to see it's written in a cipher they don't know how to read. Their solution? Capture Happosai and have him read it to them. Akane points out how incredibly stupid they've been just in time for Happosai to realize he has forgotten that cypher.
- During the Ultimate Weakness Moxibustion Arc, Cologne teaches Ranma the Hiryu Shotenha to defeat Happosai, knowing that, even if it requires the opponent to unleash their fighting spirit and follow the user in a spiral path to be used, it's incredibly powerful. Thing is, about a century before she had used it on Happosai in a fit of anger, and Happosai isn't stupid enough to fall for it again.
- When the Tendo engagement is switched to Nabiki, the greedy girl decides to deal with the other fiancees by starting a bidding war to keep them busy and possibly make some money. Problem is, one of the fiancees is Shampoo. Nabiki can barely ensnare Ukyo and Kodachi in the bidding war that Shampoo arrives and announces her presence by trying to kill her before convincing the others to help her by simply stating "If Nabiki dead, then Ranma is for free!". Nabiki very nearly died that day.
- In Rent-A-Girlfriend, Ruka seems to think that once she drives Chizuru out of Kazuya's life, she'll become the object of his affections and they can be happy together. She doesn't consider the idea that doing so would break Kazuya's heart worse than Mami ever did.
- The Rose of Versailles has pretty much every single important character doing this:
- The most egregious example is the pissing match between Marie Antoinette, at the time merely the dauphine (wife of the heir to the throne), and the Countess du Barry, former prostitute who married into nobility and had become the mistress of king Louis XV. Marie Antoinette, coming from the sober Austrian court, refused to acknowledge a former prostitute's right to be at Versailles and snubbed her for almost two years, not realizing it could be constructed as an offence to the king himself and cause a war between France and Austria (when this was pointed out to her she was properly horrified and finally talked to her in public). Du Barry didn't realize she had engaged a pissing match with the future queen of France while her own power derived from being the lover on an old man who could die soon (and in fact died less than two years after Marie Antoinette had to recognize her presence at Versailles) and started to fear for her own life when this was pointed out to her, making her try (and fail) to improve their relationship (in the end the only reason Marie Antoinette didn't do anything to her was that the King's confessor managed to get the countess exiled first, with the new queen merely confirming the exile). And the king's daughters, who hated du Barry, physically dragged away Marie Antoinette when she first tried to talk to the countess, not caring at all of the possible consequences (luckily, Marie Antoinette was able to get another chance).
- The lone exception is Oscar, with her actions during the above conflict showing it the best: at first she just wanted to enjoy the show from a safe distance (it was well before she became friend with Marie Antoinette), when forced to take a side she choose Marie Antoinette because, as much du Barry could be powerful, any victory of an old king's mistress against the future queen was bound to be reversed the moment the king died (we're even shown her thinking about that before taking her decision), and when du Barry, unable to be satisfied by her victory over the dauphine, tried to frame Oscar's mother for murder she went and delivered a scathing speech in which she pointed out the idiocy of challenging the future queen of France when du Barry's power came from her influence over an old man, getting away with holding the king's mistress at swordpoint in her own apartments. Oscar even sees the French Revolution coming, but, sadly, she's completely unable to prevent it.
- Sailor Moon:
- Chibi-Usa, suffering a Broken Pedestal moment upon learning clumsy crybaby Usagi is Sailor Moon, decides that Usagi is unfit to be Sailor Moon and steals her brooch, intending on taking it and the Silver Crystal back to the future. Not only do the other Sailors have to chase down Chibi-Usa, but so does Reubeus, who takes advantage of the disharmony and tries to capture Chibi-Usa. The end result sees Chibi-Usa's attempt to return fail, the other girls kidnapped and Usagi's legendary forgiveness being strained to the point where Mamoru has to stop her from harming the kid.
- Uranus and Neptune's Fake Defector act in Sailor Stars amounts to absolutely nothing because they failed to realize that Galaxia was wearing the same bracelets as all her minions, so their ensuing backstab attack doesn't work because she has no star seed. All they accomplished was making the final battle even more difficult for Sailor Moon than it should have by depriving her of Pluto, Saturn and themselves.
- In the Sonic X episode "Cracking Knuckles", Eggman has Amy, Tails, and Chris trapped inside one of his robots. He threatens to off them unless Sonic hands over his Chaos Emerald, and to make sure Sonic can't save them, he launches the robot over to the other side of the lake they're next to, knowing that water is Sonic's weakness. Sonic immediately exploits the obvious flaw in this plan by running round the lake and freeing his friends in about ten seconds. (Never mind the fact that Sonic has been shown multiple times to be fast enough to run across water...)
- At points in both the first and second seasons of Strike Witches, Minna pulls a gun on Mio in order to try to stop her from getting herself killed in battle. Mio is quite aware of the flaw in this bluff, and it doesn't work either time.
- To Love Ru: It never occurs to Karman that even if he somehow manages, by some miracle, to succeed in using a drill to "reprogram" Peke into his obedient clothing bot, there's no way Lala is going to be happy about it. In the more likely scenario of causing irreparable harm... the Deviluke people are warriors with planet busting powers.
- Train to the End of the World: Shizuru prepares for her trip to Ikebukuro by learning how to drive the train, but the only supplies she gathers are some junk food and a single bitter melon planter. It's only after they've left town that the other girls point out she doesn't have nearly enough food and also didn't bring any other supplies like bedding or extra clothes.
- Duke Bahurst of Trash Skill Gacha doesn't have very good decision-making skills. He has a 15 or so year history of hating his youngest son, the protagonist Crest and wanting him dead, seeing the boy as a murderer who escaped justice for daring to survive his mother's Death by Childbirth, so when Crest gets a prophetic dream that he'll get the god-given skill [Gacha], sucks up until Crest can't use said skill on command. Naturally, he throws a public tantrum, accuses Crest of lying and takes this "disgrace" as the final straw, that very night deciding to banish Crest into the [Lower World] which is an almost guaranteed death sentence, holding off only because Crest's fiancé wanted to have a chat first and she's from another duke house. After Crest's exile the next morning before dawn, he learns from the king that the pope also had a prophetic message proving what Crest said was true, and that his foolish exile of his hated offspring has probably doomed his kingdom to an invading horde of monsters. In his desperation to try and rectify things before the king utterly destroys his ducal house, his decision making just gets worse, when he's actually able to make decisions at all!
- Being both a complete idiot and supernaturally unlucky, Ataru from Urusei Yatsura has this happen to him repeatedly. A good example is the second episode: fed up of Lum electrocuting him, he asks Cherry for a way to remove Lum's powers, and is given a ribbon to tie round her horns that will neutralise her powers and can only be removed by the person who tied it. He sweet-talks Lum into letting him put the ribbon on her, and it works. Ataru is overjoyed... until the pair run into Shinobu, and Lum brags about the ribbon her "darling" gave her, causing Shinobu to run off in tears. Then, Lum decides that since she can't fly back to her ship without her powers, she'll just have to move in with Ataru permanently, a prospect he hates. On top of all that, once Lum realises what the ribbon actually does, she goes to town on him with her teeth and claws, which Ataru finds even more painful than the Shock and Awe powers he was trying to seal away in the first place.
- In Val × Love, during the School Festival, Itsuyo, Mutsumi and Natsuki make a bet that whoever wins the Miss Hokuou contest gets to be Takuma's partner in the dance party. Only after the contest is over they realize that Takuma had decided on his own who he would dance with because the sisters never told him about the bet.
