The academy provides top-class education for a student body of approximately 2500 students, from age 6 to 19, covers from academic subjects, to sports and fine arts. The admission process is notoriously harsh, which has 2 rounds: the writing exam and the formal family interview. Once enrolled, students are put into one of eight houses and they have the choice to stay in expensive house dormitories or commute. Students are awarded with a Stella Star (星（ステラ）, Sutera, Stella, lit. "Star") for distinctive academic or social achievements, but can also be punished with a Tonitrus Bolt (雷（トニト）, Tonito, short for Tonitrus, lit. "Thunderbolt") for transgressions or failing tests. A student who obtains eight Stella Stars becomes a member of Eden Academy's elite students called Imperial Scholars (皇帝の学徒（インペリアル・スカラー）, Inperiaru Sukarā), while those punished with eight Tonitrus Bolts are automatically expelled.

The Westalia Intelligence Services' Eastern-Focused Division <W.I.S.E.> (西国情報局対東課, Wesutarisu Jōhōkyoku Taihigashika) is the Westalian spy agency Twilight works for, whose main objective is to counter any initiatives within Ostania that may threaten the peace between both countries.

The plan was thwarted by Anya and her friends, for Billy saw his late daughter's spirit in Anya, letting himself to be captured by the state.

Antonio Mireles of The Fandom Post enjoyed the comedy of the title dysfunctional family as well as their personalities. He described the family setup of Loid as the straight man, Yor the "dumb character" and Anya the adorable child "that readers fall in love with," as the perfect recipe for a comedy. However, he felt the humor that comes from Yor being the dumb character was underutilized.[31] As a result, Anime News Network felt that following chapters focused on Yor made her character more enjoyable.[32] Comic Book Resources called the artist's range of facial expressions his" secret weapon" to attract readers, most notably Anya, whom Collins said, "steals every page she appears on."[33] In a review for Polygon, Julia Lee agreed, focusing on the expressive panels that really show the audience the characters are feeling.[34] In a further analysis, Den of Geek finds the Forgers' secrets as another reason for the series' popularity while also highlighting how despite Loid being a competent spy, his mission of becoming a good father is also hilarious.[35]

Anime Feminist also noted that the series' popularity is owed to the artwork, most notably Anya's multiple facial expressions and felt that the first episode was appealing thanks to the bond Loid and Anya form when the former adopts the latter, giving potential for Yor's debut.[36] Morgana Santilli of The Beat enjoyed the chemistry between the arranged family as he notes Anya makes the trio stand out.[37] IGN also enjoyed Anya to the point she could be one of the best characters from 2022, labelling here as the "adorable child character that steals every scene they are in, who will inspire a ludicrous amount of merch" while also addressing how her powers are also a symbolism of how receptive children can be. IGN also praised Yor due to how strong she can be despite early signs of a clumsy woman.[38]

Anya's popularity led to Toho make a music video heavily featuring her.[39] Additionally, a Tamagotchi involving Anya was released in June 2022.[40] In a survey conducted by FinT, Spy × Family and Anya were ranked first and fourth respectively, on the top trending things among Generation Z in Japan for 2022.[41] In the same survey, "Anya likes peanuts" (アーニャピーナッツが好き) was the no. 1 trending phrase of the year in part due to music remixes on TikTok.[41]
