Wonder Egg Priority

Wonder Egg Priority (ワンダーエッグ・プライオリティ), often stylized as WONDER EGG ✦ PRiORiTY, is a Japanese anime television series created and written by Shinji Nojima, and directed by Shin Wakabayashi. Animated by CloverWorks, it is a co-production of Aniplex, Nippon Television, and D.N. Dream Partners, which aired on Nippon TV and other channels from January to March 2021. Additionally, a special episode was released in June of that year. The story follows Ai Ohto, a teenaged hikikomori girl who has ceased attending school after the apparent suicide of a friend. After finding a "Wonder Egg," Ai finds herself in a dream world where she and three other girls whose friends also fell victim to suicide battle to protect various female suicide victims from the monstrous "Wonder Killers," grotesque representations of individuals involved in their trauma. In so doing, the girls hope to revive their lost friends.

Wonder Egg Priority was the first anime project by Nojima, known for writing several live-action television dramas. Nojima became interested in writing an anime series as he desired to reach a younger audience than he had been able to previously and to write a story which would not be feasible to achieve in a live-action production. He conceived Wonder Egg Priority as a coming-of-age drama that would blend the realistic feel of live-action television with the more exaggerated "fantasy" qualities of anime. Series director Shin Wakabayashi, in his first time directing a television anime, was recommended by a producer at Nippon TV as an ideal director to realize Nojima's vision for the series. Wakabayashi recruited numerous other young animators, often with minimal or no experience in directing television anime episodes, to join the production staff.

Upon commencing its broadcast, Wonder Egg Priority received critical acclaim from English-speaking reviewers, with praise for its high production value, elaborate narrative, characters, themes, and handling of controversial subject matter. However, reviews of the series after the conclusion of its broadcast have proven more polarized, with the eleventh episode's focus on the backstory of a previously unseen character and the special episode's conclusion to the story, often seen as unsatisfying, being particular objects of criticism. The series was also widely noted amongst industry experts and anime-focused publications for facing significant production challenges due to its small and inexperienced animation team coupled with an unaccommodating schedule, leading to the production falling behind as the staff struggled to maintain the anime's high production value. Later in the production cycle, hobbyist animators from abroad were recruited via the internet to help finish some episodes on time. Some critics correlated their polarized responses to the troubled production.

Plot
The series follows Ai Ohto, a junior high school student who is temporarily not attending school following the suicide of her close friend Koito Nagase. During a late-night walk, Ai is guided by a mysterious voice to a deserted arcade, where she finds a gachapon machine that dispenses a "Wonder Egg". That night, Ai gets drawn into a dream world where the Wonder Egg cracks open to reveal a girl, whom Ai must protect from a horde of monsters called "Seeno Evils". When the voice tells Ai that saving enough people in this world may bring Koito back, she resolves to continue buying Wonder Eggs and protecting their inhabitants. Along the way, Ai meets three other girls in the same situation as her: Neiru Aonuma, Rika Kawai, and Momoe Sawaki.

Production


Wonder Egg Priority is a co-production between Aniplex, Nippon Television, and D.N. Dream Partners. It was directed by Shin Wakabayashi, written by Shinji Nojima and features character designs by Saki Takahashi. Taracod served as concept artist, Keisuke Kobayashi as core animator, Yūki Funao as art director, and De De Mouse and Mito (Japanese musician) as music composers. The series was Wakabayashi's first time serving as series director for a television anime; he had previously directed the web short series 22/7: The Diary of Our Days. Wonder Egg Priority also marked the first time Kanata Aikawa had been cast in a leading voice role, and De De Mouse had been a music composer of an anime work.

Shinji Nojima, a well-known writer of live-action drama television, first conceived Wonder Egg Priority when he observed that live-action dramas had recently been less popular with the younger audience that he wanted to target with his next story. Nojima was attracted to the medium of anime due to his interest in reaching its engaged fandom that would often express their own interpretations in fan works, and his desire to tell a story that would not be feasible in a live-action production. Feeling that many anime leaned too far towards the fantastical, Nojima desired to find a middle ground between the realism of live-action dramas and the more exaggerated qualities of anime. As Nojima lacked familiarity with the anime industry and did not know who would be best to realize his vision, a producer from Nippon TV connected him with Aniplex, Cloverworks and Shin Wakabayashi, who would come to direct the series. Nojima said he did not consult Wakabayashi and the animation team about the scripts, as he was confident in their ability to realize his scripts as a high quality animation, and placed his complete trust in them to realize the story as they felt best. The difference in the half hour timeslot typical of late night anime as opposed to the one hour timeslots for live-action dramas that Nojima was used to was not a major creative consideration for him, as he was confident in his ability to pace the story effectively and therefore instead focused on the number of episode scripts. However, as the plot grew in complexity, he realized it would not be possible for him to finish all of his envisioned narrative in only twelve episodes, and thus some of the plot was cut from the final scripts as a result.

Wonder Egg Priority's visual style was frequently compared by critics to the works of Naoko Yamada;  Wakabayashi had previously worked with Yukiko Horiguchi, who formerly contributed character designs to K-On! and Tamako Market, both directed by Yamada, as she also provided the character designs for 22/7. Kevin Cirugeda of SakugaBlog said that though many directors, most recently inspired by Yamada's 2018 film Liz and the Blue Bird, had tried to emulate her style, Wakabayashi's collaboration with Horiguchi enabled him to replicate that style more accurately than any other director who had previously attempted such. Cirugeda did note, however, that Kyoto Animation's unique production pipeline inevitably made a perfect replication of Yamada's style nearly impossible, but that for Wonder Egg Priority, Wakabayashi and lead animator Keisuke Kobayashi had settled on a distinct style of "over-articulation" that was perceived as having "raised the volume" to distract from the small imperfections. The series marked many young animators' debuts in certain production roles, as Wakabayashi and his team recruited such new talents as Yuki Yonemori on episode 3, in his first time working as an episode director, and Yuzu Hori and Yuichiro Komuro, performing episode direction and storyboarding duties, respectively, for their first time on episode 4. Episode direction and storyboarding work on most of Wonder Egg Priority's episodes was delegated to a single animator, which Cirugeda believed was ideal as the team "dyed each episode with their own unique flavor," although he noted the possible drawback of overwhelming the inexperienced animation talents recruited to the production.

In planning Wonder Egg Priority's cast of characters, Nojima gave minimal details in the script and outlines to give the animation staff freedom to flesh them out according to their interpretations. Wakabayashi selected Saki Takahashi (who also came to debut in the role of Chief Animation Director on the series), an animator previously known for her work on Darling in the Franxx and Her Blue Sky, to do the character designs, as her initial drafts of the designs were the first to strongly catch his interest. Takahashi enthusiastically joined the project, as doing character designs for an original production had been something to which she had aspired since beginning her career as an animator, and was also intrigued by Nojima's characterizations which she said "highlighted both the darkness in humans as well as their innocence." According to Wakabayashi, the design and characterization of protagonist Ai Ohto was strongly influenced by Miu Takigawa, a character featured in 22/7: The Diary of Our Days (Wakabayashi's previous work). Takahashi's initial designs for Ai were more in line with common media stereotypes of hikikomori individuals, with a moody and dark attitude about her, however Wakabayashi, believing Ai to be a fundamentally curious and cheerful character, asked Takahashi to alter how Ai was drawn in order to further bring out that side of her personality.

There was also a strong attention to detail focused on the clothing worn by the characters, as Wakabayashi felt it was important for their attire to be realistic, as well as deliberately curated in order to express each character's personality and disposition. Rika's outfit was designed to suggest that she was "tired of caring about her looks" as a former idol, while Neiru's was meant to imply that she wore whatever expensive clothing was selected for her by her assistant. Momoe's design was noted by Takahashi as the most challenging to create, due to her androgynous design and the idea that she curated her clothing according to her insecurities about her appearance and gender presentation, coupled with the need for the characters' attire to not be "too fashionable" in the interest of realism. Takahashi noted that she believed Momoe did not have many feminine-coded clothes in her wardrobe, contributing to her choice to wear only a dress when she is asked out on a date in the tenth episode.

The show's "action director," animator Yusuke Kawakami, was previously known for having contributed to the animation of Black Clover and SSSS.Gridman. Wakabayashi had previously invited Kawakami to participate in the production of The Diary of Our Days, an offer he had to turn down due to scheduling conflicts. Kawakami joined the production primarily because he had grown tired of being in charge of action sequences that he felt were too divorced from narrative, and wished to focus not only on action but also scenes of realistic drama and everyday life that the action scenes would be designed to complement, an opportunity he felt that he would be afforded working with Wakabayashi. In collaboration with Wakabayashi and storyboard artist Keisuke Shinohara, Kawakami conceived the grounded everyday settings for the action sequences with this interest in mind. Wakabayashi tried his best to ensure the production "felt like a democratic environment" and that new ideas and communication from the staff were welcome, which Kawakami and assistant director Yuta Yamazaki agreed led to an improved quality of the final work. According to Cirugeda, Wakabayashi's careful sensitivity towards the needs and limits of his team was a strong contributor to the strength of the work's sustained quality despite tight deadlines amidst an unaccommodating production schedule.

Production issues
Information from industry insiders and several broadcast events showcase some of the issues the series faced during its production. In one instance, the staff were unable to complete the 8th episode of the series on time, and so a recap episode was instead aired in order to provide more time for the team. The production falling behind and the airing of the recap episode disrupted the overall broadcast schedule, leaving the originally planned twelfth episode initially unreleased, eventually to be reworked into the special episode aired three months later. Said special episode began with a recap segment that took up the first half of the one hour broadcasting timeslot in which it was scheduled, for which it was criticized,   as the episode had been advertised as a double length installment. While CloverWorks as a company is considered a "freelancing-heavy studio" (indicating that most of the work on the studio's projects come from freelancers, rather than studio employees), the situation became dire enough for the company to reach out to foreigners online, many of them without Japanese-language literacy or experience working on a television anime, for help with the animation production. Freelance translators Blou and Far were originally contracted for episode 10 of the series, initially helping Croatia-based animator Ani communicate with production assistant Hayato Satō. However, they became more involved in the final episodes, being credited for overseas animation assistance (作画海外協力), animation/English translation assistance (作画英語翻訳協力), and overseas animator part production assistance (海外Animator part制作進行協力) for their contributions in helping recruit and assist foreign animators, and bridging the language barrier between them and the domestic production team. The special episode reportedly entered into the second key animation process only five days before it was aired, prompting a displeased animator to air their grievances in a post on Bilibili.

Although the instance of an episode not being finished on time was widely known due to the recap episode having substituted it, the series as a whole was plagued with issues in which episodes were normally finished only hours before being aired. Several times, members of the series' production team were sent to the hospital, most notably series producer Shouta Umehara who was reported to have been hospitalized two times in a since-deleted tweet. Kevin Cirugeda of Sakugablog attributed the struggles to the production's limited pool of animation staff as well as the systemic shortcomings typical of TV anime production processes which he characterized as "incompatible" with the staff's creative ambitions. Cirugeda suggested that such issues in anime tend to occur due to production committees not caring about the "quality of the product [or its staff] beyond its marketability", which he pointed out Aniplex of being guilty of due to "shamelessly ly[ing]" as the lead company of the Wonder Egg Priority production committee, saying "anyone paying attention could notice what they were trying to hide." The troubled nature of the production was acknowledged by multiple English-language critics in discussions and reviews of the show, who attributed several of their criticisms to the production struggles. The production's use of overseas animators led critics Vrai Kaiser and Mercedez Clewis to express concerns that it might pave the way for future anime productions to do the same, which they worried could lead to similar complicity by production committees in the case of other troubled productions. Blou and Far, in being interviewed by Anime News Network about their experience on the production, advised readers that production assistants are "quite desperate" for help, often attempting to recruit foreigners with minimal regard for their skill in animation or art, and cautioned prospective animators to think carefully about their qualifications and be wary of the potential challenges and drawbacks of accepting any such offers.

Broadcast and release
Wonder Egg Priority aired on Nippon TV's AnichU programming block and other channels from January 13 to March 31, 2021. Kanata Aikawa, Tomori Kusunoki, Shuka Saitō, and Hinaki Yano, under the unit name Anemoneria (アネモネリア), performed both the opening and ending songs, respectively titled "" (巣立ちの歌) and "Life Is Cider" (Life is サイダー). Actress Nao makes a special appearance in episode 7 as Rika's mother, Chiaki Kawai. During the last episode broadcast, it was announced that a special episode would be aired on June 30, 2021. The special was scheduled for a 1-hour timeslot, although in reality, half of that time was taken up by a recap of the main series, making its effective runtime constitute a normal length episode.

Funimation licensed the series and streamed it on its website in North America and the British Isles, in Europe through Wakanim, and in Australia and New Zealand through AnimeLab. On March 30, 2021, Funimation announced the series would be receiving an English dub, with the first two episodes premiering the next day. Following Sony's acquisition of Crunchyroll, the series was moved to Crunchyroll. GaragePlay licensed the series in Southeast Asia and streamed it on Bilibili. The series received a North American Blu-ray release on April 26, 2022.

Reception


In English-language coverage, Wonder Egg Priority received near immediate acclaim upon beginning its airing. Reviews in Polygon, Anime News Network, Anime Feminist, and other outlets, were widely euphoric, strongly praising the high quality animation, soundtrack, music, voice acting, and narrative, as well as the handling of sensitive thematic material such as bullying, sexual assault, and suicide, which was generally seen as effective and captivating. The series was commonly described as one of the best new anime of 2021. Comparisons were positively drawn to the work of such directors as Naoko Yamada, Satoshi Kon, and Kunihiko Ikuhara, among others. However, the darker story elements received some criticisms, with some reviewers expressing discomfort with the anime's difficult themes, or voicing concerns that the story could fumble the handling of such topics further down the line. Discussing the production of the first few episodes, Kevin Cirugeda of SakugaBlog praised the quality of the animation, saying that director Shin Wakabayashi had made the most of his team's limitations in emulating Naoko Yamada's work at Kyoto Animation. Noting the "enchanting" first episode as one of the "best premieres" he had seen in recent memory, Cirugeda said it was unsurprising it had immediately attracted an enthusiastic audience.

In a feature for Polygon, Kambole Campbell strongly praised Wonder Egg's refreshing take on magical girl genre tropes, positively highlighting the use of magical realism and flower language (a point at which another comparison to Yamada was drawn) as well as the perceived attention to the "systemic root" of the social issues at the center of the narrative. Numerous other critics have drawn similar comparisons to the magical girl genre, citing such anime as Flip Flappers and Puella Magi Madoka Magica. However, series creator Shinji Nojima has rejected this classification; though Nojima acknowledged the similarity, he has referred to it as a fantasy series. Writing for The A.V. Club, Juan Barquin (reviewing the series' main 12 episodes) called Wonder Egg "spellbinding" and praised it for its perceived interest in catharsis for the abuse victims portrayed within the story, comparing it to rape revenge films.

As Wonder Egg Priority continued its weekly airing, the series garnered a more mixed critical response. A dialogue in the fourth episode, wherein the characters of Acca and Ura-Acca explain that the "Wonder Eggs" only contain girls because motivations of suicides supposedly differ between genders, was widely criticized,  prompting Wakabayashi to say on Twitter that a dissenting line of dialogue from Neiru had been cut for time. However, Kevin Cirugeda commented in a later Sakuga Blog post that Nojima, in an interview, had echoed the same sentiment as Acca and Ura-Acca had done in their dialogue, which he criticized as being incongruous with the perceived themes of the story, and said gave the impression that "not everyone is on the same thematic page". Steve Jones of Anime News Network initially called the series a "slam dunk," commending the explorations of idol culture and transgender themes, but described later episodes as "uneven" and having "rough patches". In commenting on the perceived declining quality of the series, Jones attributed it partially to the production difficulties faced by the animation staff. Episode 10, in particular, was praised for its heavy focus on transgender issues through the development of Momoe and introduction of one-off trans male character Kaoru, both by Jones and But Why Tho? contributor Mercedez Clewis, who said it prompted a "full-on ugly cry" due to their emotionally relating to the story as a non-binary woman. However, some criticism was directed at the choice to follow up Momoe's story, widely read as expressing validation of her gender identity as a trans woman, with the "traumatic" conclusion of her being forced to eat her animal companion.

The eleventh episode garnered particular criticisms for its late introduction of the character of Frill and the dedication to her backstory, which was seen as disrupting the show's already developing narrative arcs. While Jones enjoyed the episode, he opined it was not "the one Wonder Egg Priority needed right now." Jones called the shift in focus from the core cast to Acca and Ura-Acca a "grave miscalculation," and said that while he saw the potential for Frill's character to enrich the story, it only served to complicate the ongoing plot and deflate any potential for a satisfying finale. Clewis felt that episode 11 turned to "grimdark" territory, despite appreciating the narrative depth and sustained production value. Though they called Frill an "interesting" character who "I desperately wish I could hug," Clewis said her late introduction was "strange," and criticized the choice to tell her story from the point of view of Acca and Ura-Acca, in the perceived role of Frill's abusive parents, as "hurtful" and removing nuance from her arc. They also expressed confusion as to if Frill's "popping" tic was meant to carry sexual connotations, describing it as "uncomfortable" and out-of-place considering that the series had not previously appeared interested in sexualizing its female characters.

Reception to the airing of episode 12, the series' final contiguously aired episode, was overall polarized. Jones' review was positive, with praise for the open-ended conclusion to Ai's character arc. While he expressed cautious optimism concerning the announcement of the eventual end to the series in its special episode, he said he "would not have minded this being the final word" and that the show had, at the least, remained "interesting" throughout. Michael Goldstein of Otaku USA felt differently, saying that the incomplete nature of the story made it impossible for them to decide whether to give it a recommendation until they had seen the special. While Clewis enjoyed episode 12, they opined the series was becoming "too plotty" and said that they were deeply saddened to hear of the production crunch that the animation staff had endured, concluding their review with trepidatious anticipation for the special episode. Chris Cimi of Otaquest, while praising the show, expressed that despite its quality, they felt that knowing of the production crunch made it difficult to enthusiastically recommend. Reviewing the contiguous 12 episodes, Siliconera's Dani Maddox was mixed, praising the main characters and the series' illustration of their lack of agency as children, but felt that the anime did not give the same weight to the suicide victims seen in the Egg World segments, calling them "fodder" and opining that they were "treated horribly".

Reviews of the special episode were generally negative, with both the story and animation seen as failing to live up to the standard set by the main series. It was often said that it failed to satisfyingly conclude the story and even actively made the series worse, with criticism usually directed at the conclusion to the subplot surrounding Koito and Sawaki. Calling the episode a "disaster," Jones said, "I just can't fathom the amount of tone-deafness it takes to spin an uncomfortably creepy relationship between a teacher and student into a situation where the student shoulders all the blame for her suicide." He described it as the "single worst" way that arc could have ended, and otherwise found little to praise. Despite Jones' criticism, he said the special did not ruin the show for him, and in a "Worst Anime of 2021" list said he still felt "a lot of affection" towards it, and hoped its creators would "move onto better things." Clewis, on the other hand, said the special had negated most of what they felt was special about the anime, disappointing them so deeply that "all of my good faith for the series is burnt out" and they would not want to engage with a sequel. Writing for Fanbyte, Vrai Kaiser called the special "grossly irresponsible," and felt that it, alongside episode 12's retroactively observed implications that Ai's parallel world counterpart was mistaken about Sawaki, ruined the series overall by casting doubt on the stories of the other suicide victims previously seen in the Egg World. In contrast, writing for CBR, Xianwei Wu said the special episode was "good" despite the perceived impossibility of a satisfying resolution to the overall narrative, and expressed hope for a second season. Reviewing the full series for The Outerhaven, Josh Piedra responded positively, saying it had been worthwhile and overall "fantastic," with the caveat that the special episode did not satisfyingly wrap up the story. However, Piedra also said that he felt the special did not take away from the quality of the other 12 episodes, and nonetheless recommended the series.

Writing for Anime Feminist after the series' completion, Alex Henderson called the series "deeply disingenuous", believing it had undermined its themes of social ills and overcoming trauma by positioning Frill as "the root of all evil". Though they saw Frill as a victim of abuse from Acca and Ura-Acca, they expressed disappointment with the story's apparent siding with the latter's point of view, which they characterized as "a double-punch of victim-blaming." Pointing out the conclusion to the Koito/Sawaki subplot in the special episode, which they similarly perceived as dismissive of the relevant social issues, Henderson expressed that they were disappointed in Wonder Egg's perceived failure to offer any satisfying conclusion to its social critiques, and concluded by saying that "A discussion about the systemic violence against vulnerable young people cannot simply stay a spectacle about monsters and maidens."

In a "Best Anime Dubs" feature for Anime News Network, AJ of The Cartoon Cipher praised Wonder Egg Priority 's English dub and its "reserved" performances, which they felt suited the tone of the show well, and in particular complimented Mikaela Krantz's "carefully manipulated" vocal performance as Ai Ohto, while criticizing some minor flaws such as the inconsistent sound quality of the recording and "slight linguistic hitches".
