This isn't a show that respects you or its protagonist. Yui exists to be consumed, literally and otherwise, and the Sakamaki brothers exist to consume her without consequence. If you're watching it, you're not here for a love story, you're here to see how far the show will go, and it goes further than most anime will admit it wants to.
Yui's father arranges for her to stay with distant relatives while he works abroad, but the house she arrives at holds a dark secret. The six Sakamaki brothers living there are vampires, and they've been waiting for her: a girl whose blood calls to something primal within them. What begins as a confusing, dangerous living situation becomes a twisted game of possession and obsession, where Yui finds herself constantly hunted by men who oscillate between tenderness and menace. As days pass in this gothic household, Yui uncovers fragments of a larger mystery surrounding her own existence. Why did her father really send her here? What makes her blood so special that it captivates these supernatural beings? The brothers themselves harbor secrets, each with their own motivations and darkness. Yui must navigate a precarious balance between survival and understanding while living among predators who claim to care for her. This is gothic supernatural romance with a sinister edge, where vulnerability meets danger and nothing about her new life is what it initially seemed.
