A list of characters that appear in Hyouka
A 1st year high school student with a strict personal policy to never waste more energy than he needs to. As a result, Houtarou's motto is "If I don't have to do it, I won't. If I have to do it, I'll make it quick." Joining his school's Classic Literature Club at the request of his older sister, Tomoe, Houtarou finds his personal policy in constant danger of being broken due to the influence of the ever-curious, Eru Chitanda.
- Adorkable: Due to his frequent inability to socialize properly, especially around Eru, he comes off like this.
- Awesome by Analysis: What seems like irrelevant coincidences are all solid clues and pieces of information to Oreki.
- Brilliant but Lazy: Oreki has a natural talent in identifying clues and details that would pass unnoticed by other people, and is able to almost effortlessly put the pieces of the puzzle together. However, his top priority is to not waste too much energy.
- But Thou Must: Hates using energy, yet can never say no to Chitanda.
- Chaste Teen: For a teen-aged boy who spends his time doing as little physical work as possible, Oreki is quite conscientious of where his mind wanders when he's around Chitanda, often getting flustered and ashamed when his mind does shifts in an impolite direction.
- Deadpan Snarker
- The Drag-Along
- Four Philosophy Ensemble: The Apathetic.
- Genre Savvy: Over time, he can anticipate when Chitanda is getting close to saying her Catch Phrase.
- Great Detective: To his dismay, everyone sees him as this.
- Hates Being Touched: Never makes a scene of it, but subtly flinches every time someone gets close to him. Of course, with Satoshi and Chitanda around...
- Heroic BSOD: Goes through a particularly nasty one in Episode 11, when he realizes that his conclusion, while brilliant, was totally wrong to begin with and he was just being manipulated so the movie could end better.
- Hoist by His Own Petard: Episode 19 ends in this. He tries to prove to Chitanda that anyone can come up with a crazy theory, but the conclusions he draws from a seemingly innocuous school announcement turn out to be completely correct.
- Humble Hero: Thinks he's nothing special.
- Hyper Awareness: From body language to the simple placement of objects, nothing escapes Oreki's notice.
- Manipulative Bastard: Oreki isn't above blackmailing others if it will save him energy in the long run.
- Once he catches on to Tougaito's smoking, Oreki blackmails him into retrieving the Hyouka anthologies from the chemical safebox and delivering them to the Classics clubroom.
- Oreki deduces the identity of the Jumonji thief, Tanabe, and blackmails him into targeting the Classics Club for publicity, buying thirty copies of Hyouka, and using his position as Executive Committee president to sell Hyouka in the school's online store.
- Odd Couple: With Satoshi.
- Perpetual Frowner: For Oreki, it apparently takes more muscles to smile than to frown.
- Red Oni, Blue Oni: The blue to everyone else's red.
- Sherlock Scan: Used in Episode 3 to blackmail an upperclassman, Tougaito, who was smoking illegally in a classroom.
- The Stoic: Showing emotion usually consumes too much energy for Houtarou, however...
- Not So Stoic: When he realizes he was being used by Irisu, he briefly displays rage.
- Tarot Motifs: "The Strength"
- Thinking Tic: He has a habit of playing with his forelock when he's thinking particularly hard about a case.
- The Unsmile: "Damn, I can't smile."
- Vitriolic Best Friends: With Mayaka; they are jokingly referred to as "Kaburaya Middle's best couple". Although they constantly aim snark at each other, it's obvious they get along quite well.
- When He Smiles: Episode 19. It's nice.◊
The daughter of the wealthy Chitanda clan of farmers. An energetic and inquisitive young lady, Eru serves as the Classic Literature Club's president, as well as the source of much frustration in Oreki's life. Due to her insatiable curiosity, Eru can become quite persistent in her effort to understand things and once something has her attention, it's almost impossible for her to take her mind off it.
- Alcohol Hic/Can't Hold Her Liquor: The entire box of whiskey chocolates she eats in Episode 9 put her out of commission in Episode 10.
- Ambiguous Disorder: It's not certain exactly what's up with her, but she's definitely odd.
- Catch Phrase: "Watashi, ki ni narimasu" (I'm curious)
- Moe Stare: Her eyes practically glow, when she says this.
- Constantly Curious: To Oreki's dismay. Chitanda and her curiosity pretty much drives the plot. Without her, we would just be watching Oreki sit around all day.
- Ditzy Genius: She's a top student (ranked 6th in her year after mid-terms) and has an excellent memory, but has trouble cutting through Oreki's snark and is easily distracted, as shown in Episode 12 of the Kanya Festival arc.
- Four Philosophy Ensemble: The Optimist.
- Genki Girl: She certainly has energy to spare.
- Hime Cut
- Manic Pixie Dream Girl: Towards Oreki. One could say Oreki wasn't really alive until Chitanda showed up.
- Nice Girl: A sweet and cuddly bundle of infectious enthusiasm and idealism.
- No Sense of Personal Space: Tends to get really close to people without realizing it once she gets excited.
- Ojou: Being the daughter of an immensely rich and powerful farming clan, though she never expects special treatment.
- Purple Eyes: Her most outstanding trait, identifying her as a main character.
- Raven Hair, Ivory Skin: Chitanda is noticeably paler than most of the other characters and is immediately noted by Oreki and Satoshi to be attractive.
- Savvy Guy, Energetic Girl: With Oreki.
- Super Senses/The Nose Knows: Oreki even compares her to a dog.
- Stupid Sexy Friend
- Tarot Motifs: "The Fool".
Houtarou's best friend and a fellow member of the Classic Literature Club. Unlike Houtarou, Fukube always tries his best to lead a colorful life, and as such, is also a member of the student council as well as the Handicrafts Club. Dubbing himself a "Database," Fukube has a fantastic memory, often reading things just for the sake of gaining knowledge no matter how trivial.
- Anchored Ship: With Mayaka.
- Beneath the Mask: Actually a Sad Clown carefully hiding his obsession issues.
- Bromantic Foil: To Oreki.
- Camp Straight: He's pretty flamboyant and loves getting close to Oreki, but he only has feelings for Mayaka.
- Catch Phrase: "A database can't draw conclusions."
- Chaste Teen: Unlike many other Bromantic Foils, Satoshi shows no signs of being lecherous. This is further justified by his current attitude towards life. See Stepford Smiler below.
- Cloudcuckoolander: A mild example. He's more of a Keet but he also has some strange hobbies, not to mention his costume choices...
- Dismotivation: In some cases actually worse than Oreki in this regard.
- Four Philosophy Ensemble: The Realist.
- Genre Savvy: He realizes that his lack of talent or motivation prevents him from having "main character" capability, which results in him being a Stepford Smiler.
- Guile Hero: Rounds Oreki out by handling social affairs such as promoting the club's anthology. Satoshi is also very good at keeping the club together, being the one who mediates Oreki and Mayaka, and also encourages Chitanda's curiosity, which in turn forces Oreki to be more involved.
- Odd Couple: With Oreki. The two couldn't be any more different, yet maintain a strong friendship.
- Overshadowed by Awesome: Feels this way towards Oreki.
- Photographic Memory: A self proclaimed "Database".
- Real Men Wear Sunflowers: And Saturn, among other things.
- Red Oni, Blue Oni: The red to Oreki's blue.
- Sore Loser: Satoshi tries his best to keep it in check.
- Stepford Smiler: Episode 21 reveals that he used to be very obsessed with winning in middle school. He has since realized that he shouldn't be, so he distanced himself from whatever he truly liked so he'd lead a fabricated but enjoyable happiness. ....this includes Mayaka.
- Sunny Sunflower Disposition
- Tarot Motifs: "The Magician"
