Synopsis

Houtarou Oreki is a high school student of Kamiyama Senior High School. He tries to follow his motto of 'If I don't have to do something, I won't, but if I have to, I'll do it quickly,' and is a believer of the so-called 'energy conservatism'. However, his plan is interrupted when his sister forces him to join the school's Classic Literature Club, which is at the risk of being disbanded. Oreki joins the club along with Eru Chitanda, Satoshi Fukube, and Mayaka Ibara.

To Houtarou's dismay, Chitanda gets in the way of his 'energy conservatism' by asking Oreki to solve problems every time her curiosity arises. One day, Eru asks Houtarou to meet at a local cafe. Chitanda informs him the reason she joined the club: her uncle, a former member of the club, went missing in India and is awaiting a funeral as he can be declared as legally dead. She says she does not remember what her uncle said putting her in tears as a child and asks Houtarou for his help. Houtarou reluctantly agrees. After further consideration, Eru asks the other members of the club to assist in the investigation. Houtarou, with evidence given by the rest of the members, reveals Eru's uncle was expelled from the school against his will due to a school protest. He informs the club's traditional anthology "Hyouka", is a pun: translated in English means "I Scream" (Ice cream). This pun is a warning by Chitanda's uncle, where he wanted to tell future club members to voice their opinions.

With Eru's uncle's case resolved, the club members start preparing their annual anthology, "Hyouka". However, they are interrupted by Eru's senior, Fuyumi Irisu. She asks the Classic Lit. Club, specifically Houtarou, to research the true ending of her class' (Class 2-F) independent film, whose author, Hongou, fell ill before completing the script. The two parties end up coming to an agreement the Class 2-F will come up with possible theories and evidence, while Oreki and his friends will make their own interpretation based on the theories given by Class 2-F. Houtarou comes up with the "true" ending of the story, and the movie is played successfully with positive responses. However, other members of the Club pose flaws in his theories, and as Houtarou investigates more, he discovers Irisu's true plan: Irisu never intended to find the "true" ending of the movie, but instead made a cover-up to make Houtarou the new author, since she thought Hongou's script was too boring.

Soon after, the long-anticipated cultural festival, the "Kanya Festival", begins. The Classic Lit. Club prepares to sell the anthology "Hyouka". However, due to a misprint, they end up with 200 copies, instead of 30. Thus, the club members scramble to advertise their club by participating in school events. However, the club members soon realize strange robberies occurring throughout the school. A culprit by the name of "Juumonji" appears, robbing festival supplies from different clubs, in which after always leaving behind a note. Houtarou and the club begin to investigate, and realize the robberies are taking place in alphabetical order, a mock crime of The A.B.C. Murders. Houtarou finds the culprit to be Jiro Tanabe, a member of the school's executive committee. Jiro tried to send a code to the school's Executive Committee President, Muneyoshi Kugayama, who has quit art and the project they were working on despite being talented, which angered him. Houtarou strikes a deal with Jiro to make the final event of "Juumonji" to advertise "Hyouka" in return of Houtarou keeping this fact a secret. Unfortunately, Kugayama is unable to decrypt this code and the incident is passed off as a funny prank.

Months pass and many events happen to the Oreki and his friends. In the New Year Festival, Houtarou and Eru end up getting trapped in a wooden hut but successfully escape after sending a message to Satoshi. On Valentine's Day, a chocolate Mayaka made for Satoshi is stolen. Houtarou realizes something about Satoshi and questions him about the incident, in which Satoshi reveals he stole the chocolate due to his fear of developing strong feelings to Mayaka. Satoshi ends up calling Mayaka. As spring arrives, Eru asks Houtarou to join the Hinamatsuri, which is disturbed by a construction happening early on a bridge used in the festival. With the permission of the neighboring shrine, the route is changed and the Hinamatsuri ends successfully. Eru and Houtarou guesses a young man changed the date of the construction to get better pictures of the festival. On the way home, Eru tells Houtarou she wishes to stay in the quiet town. Houtarou tells her he would like to help with her dream, but quickly stops and says the weather is cold. Eru replies spring has already arrived, and a breeze blows through the cherry blossoms.

Production

The television anime series Hyouka was animated by Kyoto Animation. Honobu Yonezawa provided the source material, being the original author of Hyouka and the adaptation consultant for the anime. Yonezawa also participated in the process of producing the animation, but as he believed that it was more important for Hyouka to be a good anime than a novel, he entrusted Shoji Gatoh and the studio for most of the work. The key staff included Yasuhiro Takemoto as director, Futoshi Nishiya as the character designer, Naomi Ishida as the color designer, Shuhei Okude as the art director, Ryuuta Nakagami as the cinematographer, Hiroshi Karada for setting, Kengo Shigemura as editor, Tsuruoka Yota as audio director, and Kohei Tanaka as the music composer.

Critical response

Hyouka's story was met with favorable reviews for its approach to the everyday aspect of the slice of life genre. Many critics complimented the level of detail to even the less important characters of the story, and also for the show's uniqueness in the mystery genre. THEM Anime Reviews pointed out that the show was unique in the field of mysteries for dealing with "trivial but always personal" mysteries, and Anime News Network's Paul Jensen noted Hyouka's uniqueness genre-wise, claiming that it was the only show combining mystery and slice of life in that way. Others commended the storytelling, with Joshua Stevens from Crunchyroll News commenting that it was a slice of life that engaged him in ways that even K-On! could not making him feel like he was "walking alongside" the two main characters. Paige Villacin from CBR also commended Hyouka's storyline, describing it as "KyoAni's most emotionally mature shows to date". However, some critics described the show as being "dull", and others pointed out that the show lacked unity and a sense of conclusion.

Hyouka’s characters were also met with generally favorable reviews, although some critics, like Beveridge from The Fandom Post, found the characters in the show lifeless. Some critics found the characters unique, with some finding that the characters were "distinctive" and "slipping past" stereotypes. Anime News Network's Nick Creamer found that the character development reached "stunning dramatic peaks", and Joshua Stevens from Crunchyroll News wrote that Hyouka 'truly excelled' in the sense it provided a better understanding of the characters rather than just the "complexity of its mysteries". The main characters were also met with favourable commentary, and some noted that the story's main female protagonist, Eru Chitanda, had a simple persona that drove the story while having the complexity and intelligence to make her more than a "plot device". The male protagonist of the show, Oreki, was complimented for being an entertaining character, with THEM Anime Reviews noting his wit and dynamic attempts to avoid doing anything. However, some critics criticized Oreki's character, with Beveridge describing him as an "absolute downer". Other critics commented on the dynamics within Hyouka's contrasting characters, with Paige Villacin from CBR calling it the "true charm" of the show.

Critics commended Hyouka's art, with some describing it as "probably their (Kyoto Animation's) most beautiful series" and the "most beautiful television anime of all time." Critics also commented on its "eye-catching character designs". Many critics, including Beveridge, who was mostly negative about the show, complimented the show's art for its technical aspects such as lighting and background. Some critics also commeneded the music of the series, with Nick Creamer from Anime News Network claiming that though the show was not a musical standout, it had an "excellent ear for sound design".
