* ''Manga/AsteroidInLove'': [[TheQuietOne Ao]] is usually [[OnlySaneMan sensible]] and [[TheSmartGirl intelligent]], but her relatively frequent [[IdiotBall lapse of common sense]] puts her to this trope, mainly due her interest in astronomy as well of her [[TheSpock Spock]]-ish way of thinking.
* Kirino Chiba of ''Manga/BambooBlade'' is frequently behaving in a ditzy, overexcited manner. She is also ranked 20th in her year at school. Not genius level, but highly respectable nonetheless.
* ''{{Manga/Bartender}}'': The titular character, Ryu Sasakura, is a textbook example. Behind the bar, he is The Glass of the Gods, a walking liquor encyclopedia and the king of customer service, smooth as silk and slick as a silver bullet. Outside his comfort zone, he is a somewhat goofy ManChild with a strange obsession with eating gyoza.
* In ''Manga/BeautyAndTheFeast'', Yamato is mentioned to have excelled at any sport he put his mind to and was even chosen to represent Japan at a junior high level baseball tournament. But he's also air-headed and spacey, often forgetting to respond to his family's texts and failing to communicate himself properly, causing others to make assumptions about him.
* ''Manga/CaseClosed'':
** TeenGenius Hattori Heiji is a brilliant detective who always keeps on par with Shin'ichi's deductions, but can't for the life of him remember to call Shin'ichi "Conan" when they're in public (which shouldn't be that hard, since "Conan" was the first name Heiji knew him by). He also has a bit of a HairTriggerTemper, particularly when talking to his [[VictoriousChildhoodFriend childhood friend]] [[BelligerentSexualTension Kazuha]]. So much so that one [[http://www.fanfiction.net/s/3620272/4/An_Unprofessional_Opinion fanfiction]] diagnosed Heiji with Asperger's Syndrome in a fictionalized psych profile.
** The main protagonist, Shin'ichi Kudo, is introduced as an amazing detective, even given the nickname "The Modern Holmes". However, he is [[NoSocialSkills incredibly socially inept]], which was a major reason why he had little to no friends as a child, the sole exception being Ran.
* ''Manga/ACertainScientificRailgun'': Harumi Kiyama is a very intelligent scientist, but lacks even the most basic shred of common sense. For example, her thought process when it's hot essentially comes down to "It's hot, therefore I should take off some clothes." The fact that she's doing this in public doesn't occur to her. She actually becomes the source of an Urban Legend about a "Stripper Lady" because of this.
* Lloyd in ''Franchise/CodeGeass''. Brilliant mecha designer, does not understand basic human interaction. The characters are shocked to hear that he is engaged. [[spoiler:It's an arranged marriage since Lloyd is an Earl. He was only interested in the match because of his fiancee's vintage GiantRobot]].
* ''Manga/DeathNote'': [[GreatDetective L]] is a Ditzy Genius (compared to [[GeniusDitz Misa Amane]]) as he was stated by the author of ''Death Note'' to be the most intelligent character in the series, and has enough idiosyncrasies and few enough social skills that he can barely interact. Generally hyper-competent, he tends to fail in normal conversations and interpersonal relations.
* ''Manga/DeliciousInDungeon'':
** Laios is incredibly knowledgeable about monsters, surprisingly good at deduction and observation, a decent tactician, and a peerless fighter. He also once tried [[ExtremeOmnivore (successfully!)]] to eat AnimatedArmor.
** Senshi is a keen survivalist, a solid combatant, and a SupremeChef, but spending years underground and eating monsters makes him fairly spacey and dotty. After being kidnapped by orcs and claiming to have a plan, he revealed his plan was that he could use the orc supplies to make bread.
* ''Manga/{{Doraemon}}'': Although Doraemon is the smartest of the main characters and seems to have a vast knowledge of many different subjects, he ended up the clumsiest of his kind due to a problem during his production, and will rarely get anything done when he's nervous.
* ''Franchise/DragonBall'':
** Bulma, especially in the English dub. She's one of the brightest minds in the world, being able to make brilliant inventions out of junk in minutes, however, she tends to make bad judgement calls. This is best shown in the Red Ribbon Army Saga where she invents a high-tech spy drone and sees that Goku is planning to attack the Red Ribbon Army HQ. After the drone gets blown up she realizes they need to call for help, but she complains they don't have a phone. Turtle then points out that if she could make a drone then a phone shouldn't be any trouble for her, to which she gets the point and sets to work making the phone. All this and yet somehow she gets the idea to become a treasure hunter. She gets [[CharacterDevelopment only slightly better at this over the course of the series]], in the sense that she doesn't walk headlong into danger without thinking first so much.
** It runs in the family, because her father, Dr. Briefs, is even worse -- he's a genius in anything mechanical, but has absolutely no common sense.
** While Piccolo is easily the smartest of the Z-Fighters and a good tactical genius, several of his battle plans fail because [[DidntThinkThisThrough he overlooks glaring flaws in them and doesn't notice until it's too late for him to do anything about it]]. For example, when fighting Raditz, he breaks out the Special Beam Cannon to take him down, but it fails the first time because he didn't actually think to ''immobilize'' Raditz beforehand.
* ''Anime/GirlsUndPanzer'': Miho Nishizumi. At first glance, she's shy, socially awkward, and usually clumsy. She is also an expert tactician and commander in the sport of Sensha-do/Tankery, due to being from one of the most prominent families in the sport. The only thing that sets Miho apart from her family is that Miho [[NoOneGetsLeftBehind values the safety and efforts of her team]] which clashes with her family's "win at all costs" belief.
* ''Anime/GunXSword'': Joshua Lundgren is one of the greatest mecha engineers in the world... and doesn't understand why women scream when a guy walks into the girl's bathroom.
* ''Manga/HayateTheCombatButler'': Maria and Nagi have both skipped grades and know multiple languages. When they are split up while on a train, Hayate is torn between protecting his master or staying with the maid until Hinagiku shows up for a [[BigDamnHeroes less-than-fully-heroic rescue]] because they are completely clueless about the world.
* ''Manga/HidamariSketch'': Miyako acts like she has a case of AttentionDeficitOohShiny, but her artistic and academic abilities are levels above the other characters--she's one of the few people who is BrilliantButLazy but not BookDumb. That said, her use of GratuitousEnglish is also quite terrible...
* ''Manga/KaguyaSamaLoveIsWar'':
** Most of the humor in the series comes from Kaguya and Miyuki being this: they're legitimately very bright, but they also suffer from badly warped ideals, weird upbringings, and ComplexityAddiction, resulting in them turning every single exchange into a BattleOfWits. Most of these "battles" end in a stalemate because of them managing to outsmart themselves. Kaguya, for instance, nearly had Miyuki dead to rights in an exchange that would have ended in him admitting he was a virgin, but revealed in the process that she was so sheltered about sex that she thought "your first time" meant ''kissing.''
** It becomes clear as the series goes on that Fujiwara is more flaky than stupid, which isn't helped by her "best friends" sabotaging her test scores by tricking her into not studying. She can speak five languages, design functional games, elaborate scams, is a skilled pianist, and still scores slightly better than average on tests in a very difficult school despite almost never studying.
* ''Literature/LoveChunibyoAndOtherDelusions'': Sanae Dekomori from the anime adaptation may be a {{Cloudcuckoolander}} out of her [[{{Chuunibyou}} delusions]], but she's still the top student of her grade, to Yuuta and Shinka's utter surprise.
* ''Manga/LuckyStar'': Miyuki Takara is extremely smart, talented, gets very high grades, and has a lot of knowledge about different subjects that the other three main characters don't. However, she can be rather clumsy and naive, and is prone to spacing out when she's thinking too much about something. That's probably why Konata is always saying how {{Moe}} she is.
* ''Manga/MonthlyGirlsNozakiKun'': Yuu Kashima is good at almost everything, but she has an off-kilter thought process and can never seem to figure out when the things she does will get her in trouble.
* ''Manga/MyHeroAcademia'': Denki Kaminari. He is considered the dumbest person in class 1-A, but at the beginning of the story we are told that UA is the top Hero school in Japan and perhaps the entire world, and that in order to get in you basically had to ace middle school, showing that literally everyone at UA who is considered "dumb" such as Mina Ashido, Rikido Sato, Tetsutestsu Tetsutestu, and Ejiro Kirishima, are actually all still quite intelligent. Denki is a special case as he does have many real moments of stupidity, but he's still at the top school in the world meaning he is simply the dumbest genius in a school of geniuses.
* ''Manga/{{Nichijou}}'': Professor Shinonome is a technological wunderkind who built a RidiculouslyHumanRobot and a device that allows her cat to speak like a human. She's also 8 years old, and [[InnocentProdigy possesses all the naivete of a kid her age despite her amazing mechanical aptitude]].
* ''Manga/OuranHighSchoolHostClub'': Tamaki Suoh is so ditzy that despite starting a HostClub, he mistakes his romantic feelings for Haruhi as wanting to be her ''father''. He also has the second-highest grades in his year without even trying, to the frustration of some.
* ''Manga/PokemonAdventures'': [[IncomingHam Black]]. Type match-ups, move accuracy, evolutionary lines, detailed information on every Gym Leader and Elite Four member (including their team line-ups), Black studied them all before going out on his quest ToBeAMaster. Pity he has NoSocialSkills and feels that it's appropriate to shout out his dreams to people who are quickly going deaf.
* ''Manga/{{Saiyuki}}'': In ''Gaiden'', Tenpou is shown to be a brilliant strategist, but seems baffled by everyday life and would probably be buried under a pile of books almost permanently if it wasn't for Kenren.
* ''Manga/{{Sekirei}}'':
** Mikogami Hayato graduated from college before the age of 15 and is cunning enough to outsmart the resident ManipulativeBastard. On the other hand, he's a [[{{Keet}} hyperactive teenager]] prone to AttentionDeficitOohShiny moments. He treats the Sekirei Plan like a super-exciting game of ''Franchise/{{Pokemon}}'' and expresses the desire to transform the world into something out of a video game if he wins.
** BigBad Minaka Hiroto was also this before he became TheWonka.
* ''Manga/SleepyPrincessInTheDemonCastle'': When properly motivated, Princess Syalis is scarily competent; she breaks out of her cell so easily that the demons eventually give up on locking her in, she repeatedly manages to {{MacGyver|ing}} sleep aids out of random objects, and it's eventually revealed that she's a well-practiced bureaucrat who's capable of keeping the castle running just as well as (if not better than) the Demon King. However, she also has a tendency for ''extreme'' tunnel vision; getting so focused on her objective that she disregards most of the consequences of her actions, causing her to border on both LethallyStupid (her attempt to use magic as a sleep aid ended up [[NoSelfBuffs knocking out everyone in the castle except herself]]) and TooDumbToLive (using a lethally poisonous mushroom as an impromptu mattress, ''repeatedly'').
* ''Anime/SpaceDandy'': Dr. Gel is said to be the Gogol Empire's greatest scientist, and is even shown building impressive technology and performing complex calculations and equations to back this claim. That said, he suffers from SkewedPriorities and repeatedly fails at his assigned task of capturing the title character. He's so bad at it, in fact, that [[UnknownRival Dandy doesn't even know that Gel exists]] until the final episode. Gel simply assumes that [[SeeminglyProfoundFool everything Dandy does is an ingenious plot to foil him]], and while Dandy [[GeniusDitz is smarter than he looks]], Gel's repeated failures can usually be chalked up to [[BornUnlucky bad luck]] and [[IneffectualSympatheticVillain cartoonish incompetence]].
* ''Anime/TomicaHyperRescueDriveHeadKidouKyuukyuuKeisatsu'': Jou Kurumada. He's a skilled mechanic and brilliant strategist. Other than that, he can be rather clueless. The drama of an entire episode is drawn from the fact that he can't remember the contents of a phone call he had with his wife just the other day.
* ''Manga/{{Yuyushiki}}'': Yui sees Yuzuko as this. She does do well in school, but as Yui points out...
-->'''Yui:''' ''[on Yuzuko's {{def|iedtrope}}ying SmartPeopleWearGlasses]'' She really is pretty smart. It's her ideas that are dumb.
* Kirino Chiba of ''Manga/BambooBlade'' is frequently behaving in a ditzy, overexcited manner. She is also ranked 20th in her year at school. Not genius level, but highly respectable nonetheless.
