It starts as a magical girl show and then refuses to behave like one. Five stolen seeds out of Evergreen, a Queen's agent named Natsuki who can't finish the job himself, and a middle schooler told she's "the only one" who can, which is the kind of line that sounds like destiny until you notice what it costs her. Chihaya becomes Magical Warrior Carmine and the fights stay small, quiet, almost domestic, because the real damage is that the people carrying the seeds are ordinary humans someone loves. Then her mother shows up where a mother has no business being, and the series stops being about retrieval at all. Yes, the source was an erotic game, and yes, this thirteen-episode version spends its runtime on grief and obligation instead, which is exactly why half the audience bails by episode three and the other half never shuts up about it. If you want spectacle, go elsewhere. If you want a transformation sequence that feels like a burden, stay.
A middle school girl named Chihaya receives a shock when Natsuki, a mysterious agent from another world, appears to recruit her for an impossible mission. Five dangerous magical artifacts known as seeds have vanished from Evergreen, a realm hidden beyond reality, and somehow landed on Earth where they're corrupting people from the inside out. Only Chihaya can stop them, Natsuki insists, though he has no explanation for why she alone possesses this power. When danger strikes, Chihaya transforms into Magical Warrior Carmine, wielding abilities she never knew she had. But saving possessed victims becomes the least of her concerns. Her mother's secretive knowledge of Evergreen raises uncomfortable questions. Her memories of a father who died before she was born feel unnaturally real. And her recurring dreams of a beautiful world she's never visited grow more vivid each night. As Chihaya hunts the seeds and confronts supernatural threats, she uncovers a conspiracy woven through her own family's past. The line between her world and Evergreen blurs, forcing her to question everything about her identity and why she was chosen for this role.
