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 series centers on Ai Ohto, a teenage who stops attending school following her friend's suicide. After discovering a 'Wonder Egg,' she enters a dream world where she and three other girls—each mourning a lost friend—fight grotesque "Wonder Killers", manifestations of trauma linked to suicides, and their goal is to resurrect their friends by protecting victims in this surreal realm.
Wonder Egg Priority marked Nojima's first anime project, following his work on live-action dramas. Seeking to reach younger audiences and explore stories impractical for live-action, he conceived it as a coming-of-age tale blending live-action realism with anime fantasy. Nippon TV producer-recommended debut TV anime director Wakabayashi assembled a team of mostly inexperienced young animators to realize this vision.
Initially praised by Western critics for its production quality, narrative complexity, and sensitive treatment of difficult themes, Wonder Egg Priority garnered more polarized reviews after its finale. The eleventh episode's focus on a new character's backstory and the special episode's conclusion drew particular criticism. Industry observers noted the production's struggles—an inexperienced team and tight schedule necessitated recruiting foreign hobbyist animators online to complete episodes, with some critics linking these challenges to the inconsistent reception.
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.
Characters Main
A 14-year-old girl with heterochromia, which has led her to be the subject of bullying. In the past, Ai became friends with Koito Nagase, a girl that had newly transferred from another high school. The two became close, as they only had each other. Tragedy ensued when Koito unexpectedly committed suicide by jumping off the roof of their school building. Following Koito's suicide, Ai ceased attending school. Ai is buying Wonder Eggs in order to bring Koito back to life, as well as discover the truth as to why Koito committed suicide. Her weapons of choice are a four-color ballpoint pen that can transform into a giant mace, a long, yellow-colored glowing ribbon-like bladed whip, two yellow penlights (light sticks) that can be used as double-bladed weapons, and prayer beads that allow her to see invisible Wonder Killers.
A quiet and reserved 14-year-old girl who makes no initiatives to get to know people. Despite her age, she is the president of a large company. Sometime in the past, Neiru was hospitalized after being violently stabbed by her sister. While recuperating from stabbing in the hospital she was informed that her sister committed suicide after assaulting her by jumping off of a bridge. The assault left Neiru with painful scars across her back, as well as complex feelings regarding her sister. Neiru is buying Wonder Eggs in order to bring her sister back to life. Her weapon of choice is a compass that can transform into either a great sword, two gigantic pliers with reactors, an assault rifle, a sniper rifle, or a pistol.
A brash and outspoken 14-year-old girl who does not hesitate to say what is on her mind. Rika previously was a junior idol, and amassed a small fanbase. After discovering one of her biggest fans—an overweight girl named Chiemi—was shoplifting in order to give her gifts, Rika tried to stop Chiemi's shoplifting by insulting and lying to Chiemi in an attempt to turn Chiemi on her, claiming that she could not be friends with a fan and "would be embarrassed to be seen with a fatty." She would later discover that Chiemi died after starving herself thin. Rika is buying Wonder Eggs in order to bring Chiemi back to life. Her weapon of choice is a pair of two box cutters that act as swords.
A 14-year-old girl who is often mistaken for a boy due to her androgynous appearance. She is the niece of Ai's homeroom teacher Shūichirō Sawaki. Momoe was once close friends with a girl named Haruka, who was the only one of her classmates that recognized she was a girl and treated her femininely. One day, however, Haruka made romantic advances toward Momoe and requested that she touch her. Momoe rejected Haruka's advances and Haruka later committed suicide, leading Momoe to believe that she may have been responsible. Momoe is buying Wonder Eggs in order to bring Haruka back to life. Her weapon of choice is an umbrella with a spearhead at the end.

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 and 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 Prioritys 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 Prioritys 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.
