Bocchi the Rock!

Bocchi the Rock! (ぼっち・ざ・ろっく！) is a Japanese four-panel manga series written and illustrated by Aki Hamaji. It has been serialized in Houbunsha's manga magazine Manga Time Kirara Max since December 2017. Its chapters have been collected in six volumes as of August 2023. A spin-off manga series, titled ''Bocchi the Rock! Gaiden: Hiroi Kikuri no Fukazake Nikki'', began publication in July 2023.

An anime television series adaptation produced by CloverWorks aired from October to December 2022. Both the manga and the anime received widespread acclaim for the animation, writing, voice acting, comedy, characters, music, and exploration of social anxiety.

Plot
Extremely anxious and socially awkward Hitori Gotō longs to become a rock musician in spite of her struggles, while fulfilling her desires to one day make friends. She is suddenly given a chance to do so after she is taken in by another girl, Nijika Ijichi, to become a member of her newly formed Kessoku Band.

Kessoku Band


Kessoku Band (結束バンド) is the central band in the series, based in Starry, a live house in Shimokitazawa. The members' family names are derived from the real-life J-rock band Asian Kung-Fu Generation, with their instrumental roles matching as well (for example, the Yamadas of both bands play bass).
 * Hitori Gotō (後藤 ひとり) / Bocchi (ぼっち)
 * The lead guitarist of the Kessoku Band. An extreme introvert who has trouble with most social interactions. Having been inspired by her father, she learned how to play the guitar in her first year of middle school, thinking this would help her make friends. Despite becoming incredibly skilled at playing guitar and having a small fanbase online (under the alias "guitarhero"), she still has not been able to make friends as easily until she was dragged into playing with Kessoku Band. Since then, Hitori has gained a few friends and is learning to interact with other people. She is usually seen wearing a pink tracksuit, which she even wears over her school uniform. Her surname comes from Masafumi Gotoh. Her nickname Bocchi is a reference to hitoribocchi (一人ぼっち), a term for being alone.

Development
After finishing with her first title in Manga Time Kirara Max (Kirari Books Meisouchuu), which was mainly about young girls dealing with moe things, Aki Hamaji considered doing a manga about bands next, as listening to bands is one of her favorite hobbies. However, she did not have any actual experience being in a band or playing an instrument prior to the making of the series, so she conducted extensive research by doing things like asking an acquaintance more familiar with the indie band scene, listening and reading more about the culture, and visiting places that are prominent to the scene (like the live house Shelter in Shimokitazawa, which would end up being the model for the live house Starry).

Being aware of the popularity of K-On!, also a Houbunsha-published series with a band setting, Hamaji intentionally set the story around a live house instead of mainly in school to differentiate it. She also admitted using Beck as a reference in making the series as well. Most of the chapter covers have references to the music videos of Japanese rock bands; most of them would be songs that she liked to listen to, while some others were instead relevant to their respective chapter stories. She also avoided using onomatopoeia or creating lyrics for any of the performance scenes, leaving the finer details of the band's performance to readers' imaginations, although some of the songs do have names originally mentioned in the manga. While the manga is mostly in a four-panel format, in serious moments she intended to have it follow a conventional manga format as well.

In an interview published shortly after the anime finished airing, Hamaji revealed that the designs of most of her characters in the series were purposely done in a simple way; commenting specifically about Bocchi's design, she said she intentionally created a character who doesn't have any fashion sense, and her pink hair color may have been inspired by Kaoruko Moeta from Comic Girls (also a Kirara Max series), although pink-haired characters are common in Kirara titles. She also said that she decided on the color of Bocchi's guitar to be black because of how it made a good balance with the color scheme of her design, but chose a Gibson Les Paul Custom as the exact model of her first guitar because it was the first result when searching for a guitar with that specific color on the internet. She also admitted that Bocchi's personality is a projection of hers and that she relates to Bocchi the most among all characters.

Anime adaptation
Prior to the greenlighting of Bocchi the Rock!'s anime adaptation, character designer and chief animation director Kerorira was a fan of the manga for its comedy, art style, and characters, and in particular Hitori's "unhinged" nature. While meeting with animation producer Shouta Umehara at an illustrator exhibition, Kerorira brought up Bocchi in conversation and expressed a desire to work on an anime adaptation of the series. As it so happened, Aniplex had just recently proposed such a project to CloverWorks, as Umehara learned when he inquired to his superior, Yuichi Fukishima, about the possibility. Kerorira joined the project (becoming the first to do so) as its character designer after expressing his enthusiasm for the series and presenting his drawings of the characters. In addition to the character designs and animation supervision, Kerorira also contributed a significant amount of key animation to the project (estimated by Umehara to amount to somewhere between 500 and 600 cuts of animation, around two episodes' equivalent), which he stated was done to provide the other animators with an understanding of the "platonic ideal" of the anime's production value. Kerorira felt that providing such a baseline as the chief animation director would allow for smoother collaboration, as it would lead to a creatively unified end product while allowing the animation staff to incorporate their own individual expression and limit the number of corrections that would need to be made after the fact.

Series director Keiichiro Saitō, who previously served as episode director on The Idolmaster SideM, and Sonny Boy, came to work on the anime adaptation of Bocchi the Rock! after Kerorira recommended him to animation producer Shouta Umehara. As Umehara was familiar with Saitō's work, having served as an episode director for The Idolmaster, he considered Saitō to be an ideal choice, and Saitō joined the project as director a few days later after discussions with Umehara and Kerorira. Erika Yoshida, the screenwriter in charge of series composition, was recommended on referral from a colleague of Umehara's at Aniplex, who had previously collaborated with Yoshida on Love Me, Love Me Not. As he was aware of Bocchi 's similarity in premise and genre to K-On!, Umehara spoke to Kerorira, asking him what unique qualities Bocchi had that would distinguish it from K-On!, and worked to help ensure that capturing those aspects of the series was a priority of the production.

In reading the manga prior to production, Saitō was attracted to the relationships between Bocchi and the supporting cast, which were not as intimate as relationships depicted in similar works and gave Saitō the impression that "they respect each other’s individuality and personal space." He found this quality of the story to be both personally relatable and distinctive. Saitō also liked the ways in which Hitori's expressions were often exaggerated to perceptibly disturbing extents, in contravention of conventions. This aspect of Hitori's characterization was expanded upon in the anime, as Saitō believed that "girls who are flawlessly beautiful aren’t as cute as girls who are a little mysterious or sometimes make weird faces." Kerorira additionally said that Hitori's withdrawn nature made it more difficult to depict her emotions visually compared to those of the other characters. As such, her basic facial expressions were limited, while the animation relied on the more "slapstick" scenes of exaggeration to depict her emotions. Although consideration was taken to ensure Hitori was consistently cute, even when the animation was exaggerating her facial features, the comedy of such exaggeration was generally prioritized.

In adapting Bocchi the Rock! from its original 4-koma format, Saitō and Yoshida introduced numerous substantial differences from the source material, such as rearranging events and altering some jokes to aid the anime version's pacing and surreal presentation. Saitō and Yoshida added more of a surrealist bent to the anime as they wanted to prioritize comedy and emotion over a wholly realistic depiction and felt that the choice of cutaway gags in the anime allowed them to better convey the story while ensuring that every episode had a clear focus. In integrating these cutaways into the anime, Saitō chose to contrast main character Hitori's thoughts during her instances of introspection and "strange" behavior with the external reactions to and conversations about Hitori among the supporting cast. This was done both for storytelling considerations such as the direction and pacing of certain scenes and also to present Hitori more empathetically by showing that the supporting cast did not regard her as pathetically as she would be wont to believe. Saitō said that whether or not a conversation between the supporting cast occurring during these moments needed to be depicted in detail or not was one of the most difficult aspects of the production.

To create the live concert scenes of the anime, the production team recorded physical actors playing the concerts. The recording was then adapted into a computer-generated previsualization so that the animators could establish their preferred shot direction for the scenes using a virtual camera system. The previsualization was then used as the basis for the final animation. To ensure that the characters were portrayed accurately in these scenes, the actors were given information about the characters and advised on how to convincingly physically act as them. The music production team at Aniplex was consulted by Saitō to ensure that the ambient noise in the concert scenes was accurate to reality, although it was sometimes omitted when Saitō deemed that it would detract from an important dramatic scene.

Stage play
A stage play adaptation at the Theater Milano-Za in Tokyo, titled Live Stage "Bocchi the Rock!", ran from August 11–20, 2023. The play is written and directed by Akira Yamazaki. The Blu-ray and DVD of the stage play was released on February 28, 2024.

A re-performance and the sequel of the stage play, were scheduled to be perform in September 2024.

Popularity
The anime was not as highly anticipated by audiences as many more previously established series airing at the same time, such as Chainsaw Man and Mobile Suit Gundam: The Witch from Mercury. However, as the anime progressed, it gained a larger audience due to clips from the anime going viral online.

The series' sudden growth in popularity following the airing of the anime prompted an unexpected influx of fans who formed an excessive line at mangaka Aki Hamaji's booth at Comiket 101 on December 30, 2022, prompting event organizers to direct Hamaji to a different location. Consequently, Hamaji moved her booth outside of the event hall and published a map directing fans to its new location. Wares at Hamaji's booth were exhausted by 12:51 pm that day.

The manga had also reportedly been sold out in various bookstores both during and after the anime's broadcasting, prompting Houbunsha to announce three rounds of reprints of all of the manga's volumes, including the Anthology Comic, one month after the final episode aired, with added copies printed for each of those rounds. The magazine the manga is published in, Manga Time Kirara Max, also reportedly sold out of its January and February issues on their first days of circulation, helped by the January issue featuring a guitar pick as a bonus to celebrate the anime's airing.

The popularity of the anime also led to skyrocketing demand for musical instruments, especially guitars, where instrument shops recorded a spike of instruments being sold right after the anime ended. Models used specifically by the characters (like the Gibson Les Paul and Yamaha Pacifica guitars used by Bocchi) went out of stock, with no definite restock date. Sales of instruments to beginners also increased (with stocks being depleted in some cases), as many people started to pick up instruments to play due to the series.

Shimokitazawa, particularly the Shelter live house that Starry is based on, also recorded an increase in visitors making otaku pilgrimages to places appearing in the series. However, uneasiness and worries from others, including shelter management, resulted from obtrusive behavior by visitors, which included attempted unpaid viewing of live performances. A sign written in English, Japanese, and Korean was installed by Shelter to discourage visitors from descending the iconic stairs to its side entrance. The official website of the series subsequently issued a reminder to fans to behave properly when visiting such places and to support paid performances.

Despite all the issues, the town still managed to take advantage of Bocchi the Rock! 's popularity. Kessoku Band has been appointed as Shimokitazawa official ambassadors as part of the town promotion of Shimokitazawa Curry Fest 2023, where food premises around Shimokitazawa offer various curry menus and will hold a stamp rally where visitors can redeem merchandise by collecting stamps from purchases, which prizes include Kessoku Band-featured merchandise as well.

Sales
The anime's popularity boosted manga sales as the whole series recorded 202,481 copies sold, earning it twelfth place for most manga sold in the month of December, according to Oricon. Lack of stocks later hampered January sales, but as large reprints replenished stocks in most storebooks, the manga recorded another big sale in February, with 193,348 copies of the whole series sold, the seventh most for that month. The increase in demands and reprints also surged the numbers of circulations of the series, as in January 2023, Houbunsha announced the series had marked one million copies in circulation, not including the digital versions, and subsequently hit 2 million copies in circulation in March. The series hit 3 million copies in circulation in January 2024. It was Yen Press' fifth-best-selling manga title that debuted in 2023.

Critical reception
Christopher Farris complimented the manga's first volume and described Hitori "Bocchi" Gotō: "She's technically the least-suited person to be standing in the spotlight of anything, but that means most of the entertainment value manifests in the way she's a commanding cringe callout post for readers who relate even a little bit to her litany of struggles." Christopher also highlighted the dramatic and humorous moments about not just Bocchi's anxieties and the natural talent but the overall struggles of forming and following the path of a performing band. He concludes: "There's a density to the format that means you feel like you're getting a lot of bang for your buck just in this first volume (including the appearance of everyone's favorite, Kikuri Hiroi), though that can also mean things feel just a little dragged-out in places. But a structural nitpick or two can't stop Bocchi the Rock! from being worth checking out on its own terms."

Accolades
In 2019, the manga series ranked eighth at the fifth Next Manga Awards in the print category, organized by Da Vinci magazine from Media Factory and the Niconico website.

Sales
Blu-ray and DVD sales reached 14,821 and 1,972 copies, respectively, in the first week of the release of the first volume and placed second for the most Blu-ray sales that week. The second volume records 16,205 and 588 copies sold, respectively, for Blu-ray and DVD in the first release week. The third volume records 17,856 Blu-ray and 1,535 DVDs, and the fourth records 17,196 Blu-ray and 1,451 DVDs on their first week of sales.

The album Kessoku Band sold 36,530 copies on release day and subsequently 72,533 copies in the first week, charting first place in Oricon and Billboard Japan for the top album that week and continuing to maintain its performance in the weekly top 10 album sales. It was certified gold in January 2023 and later platinum in May 2024 by the Recording Industry Association of Japan (RIAJ) after it reached more than 100,000 and 250,000 physical sales, respectively. The opening theme, Seishun Complex, was also certified gold in streaming when it reached 50 million listenings on streaming platforms in November 2023, and one of its insert songs, If I Could Be a Constellation follows on June 2024.

The first part of its compilation film, ''Bocchi the Rock! Re:'' saw the film topping the weekend chart of Japan's box office on its opening weekend, with earnings going up to 218 million yen (approximately 1.39 million US dollars) and 140,000 attendees recorded. This was the first time an anime compilation film (with the contents being only a recap of its original series) managed to top the chart.

Critical reception
In Anime News Network's Fall 2022 Preview Guide, the anime received widespread critical acclaim from most contributors. In general, the anime was praised for its writing, characters, animation, and portrayal of social anxiety. Caitlin Moore praised the realistic depiction of Hitori's guitar playing as well as the "slightly acerbic" comedy, which, in her opinion, helped avoid the show becoming "too gentle" and contributed to Hitori's relatability. James Beckett similarly complimented the anime's attention to detail regarding the musical activity, in contrast to other similar anime, which he felt were generally not attentive to such logistical elements. Nicholas Dupree opined that Hitori's character felt "authentic" to "the kind of introverted kid who would wear band merch and carry their guitar to school in a bid to seem interesting" and was particularly enthusiastic about following the show, saying it was "so laser-targeted at my tastes." Rebecca Silverman's response, in contrast, was middling, as while she agreed that Hitori was relatable, she believed that the anime "seems to conflate introversion and social anxiety" and did not like the visuals. In spite of these criticisms, she called the first episode "engaging." Richard Eisenbeis said that the story had "solid lessons being told" but said that the humor (which he called "cringe comedy") was not to his taste, but acknowledged that others who enjoyed the jokes would find the anime more palatable.

In a review for IGN, Rafael Motamayor strongly praised the anime for its story, themes, and visual creativity, comparing it favorably to K-On! and Keep Your Hands Off Eizouken!. Motamayor also highlighted the similarity in the premise between Bocchi and Komi Can't Communicate and opined that the former improved on the latter by not "making light of" Hitori's personality for the sake of its humor. The diversity of the anime's visuals and inclusion of CGI and stop-motion sequences were also praised.

In a feature for Crunchyroll, Adam Wescott praised the narrative and character of Hitori, comparing both positively to Watamote, and also praised the visual inventiveness of the "anxiety attack" sequences.
