Critical response When it came to the adaptation,
Anime News Network gave the first episode of the
Heavenly Delusion anime a positive response due to its dystopian premise and the amount of characters, and compared in to
Blame!, and the animation of the human and monster designs. They noted the series appears to heavily focus on gender, not on
Kiruko's themes that come across as negative as the reviewer still found the character interesting based on how they are written. The reviewer praised the relationship between
Maru and Kiruko for the way they care for each other, and noted the flashback's incestuous "angle might just be sensationalism for the sake of it, but I don't mind that extra splash of taboo when the full picture is this interesting". Toni Sun Prickett of
Anime Feminist enjoyed the handling of the animation and the dynamic between the two leads, and said Maru looks suspiciously similar to another character in the parallel story. Prickett also mentioned the amount of gender-based violence that occurs when Maru and Kiruko are attacked. With the eventual revelation Kiruko is a young man who had his brain transplanted into his sister's body, the website was optimistic about the handling of the main duo; for Maru still appearing likable when confessing his feelings to Kiruko and not sounding homophobic in response to the twist. Prickett was troubled by the repercussions of this twist on Kiruko's feelings because her early scenes in the first episode now made her look incestuous. Alice Gallo of
Comic Book Resources also noted the series gender norms due to the complexity of Maru's and Kiruko's relationship because Maru seems to retain his affection for Kiruko despite knowing he is male. Gallo also compared Kiruko with a transgender character who is trying to accept the idea of having a female body. Before the series' release,
Polygon stated despite the absence of talented creators in the production staff, aside the studio and the composer Kensuke Ushio, the series looks intriguing and the animation is impressive.
Clarín and
Meristation compared the anime to the video game
The Last of Us for its post-apocalypse setting with the main duo exploring areas like
The Last of Us protagonists
Ellie and
Joel.
NME enjoyed the mystery and lack of exposition dumps, positively comparing the premise to those of
The Leftovers and
Station Eleven.
IGN praised both the animation and the dynamic of the leads as the best pars of the anime.
The Philippine Star praised the series for focusing on
gender dysphoria through the relationship between Maru and Kiruko without
queerbaiting audiences in a manner similar to "switcheroos" like
Ranma ½ and
Sailor Moon. The voice actor for Kiruko,
Sayaka Senbongi, was excited to voice the character because she knew of the manga and liked Kiruko before being cast in the role. According to Ishiguro,
Production I.G made Kiruko more sexually appealing than his own rendering. The scene in which Totori tries to seduce Maru also received Ishiguro's attention because he found it more erotic than the equivalent scene in the manga. Furthermore, Ishiguro claimed that he cried when watching episode 8, much to his surprise as he originally wrote it himself. Ishiguro said Robin was "born in the story out of sheer necessity", and was surprised he became the most-hated character in the series.
