In Episode 1, the story introduces a nurse and a doctor conspiring to murder the nurse's young ward, while a young man grapples with unrequited love, unaware that his affection is directed toward a woman who loves another woman. Kaguya intervenes in these human affairs, delighting in granting people's deepest desires, only to let them face the unforeseen consequences. Her interventions lead to unexpected transformations and chaos, blending dark humor with eroticism.
The episode is noted for its 1990s animation style, with some inconsistencies in character design, particularly in facial features and eye positioning. The voice acting reflects the era's standards, contributing to the overall atmosphere of the series. The mature content is present but not overly explicit, aligning with the storytelling approach of that time.
"Rei Rei" combines supernatural manipulation with human desires, offering a narrative that explores the complexities of wish fulfillment and its repercussions. The series holds a certain appeal for fans of vintage anime, despite its mixed reception and dated animation quality.
